A Systematic Review of the Relationship between Serum Vitamin D Levels and Caries in the Permanent Teeth of Children and Adolescents. Dent J (Basel) 2024; 12:117. [PMID: 38668029 PMCID: PMC11048958 DOI: 10.3390/dj12040117] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Revised: 03/18/2024] [Accepted: 04/19/2024] [Indexed: 04/28/2024] Open
Abstract
This systematic review critically evaluates the association between serum Vitamin D levels and dental caries incidence in the permanent teeth of children and adolescents. The search strategy comprised three databases (PubMed, Scopus, Embase), up to November 2023, targeting studies on the correlation between Vitamin D and dental caries in permanent dentition. The eligibility criteria focused on observational studies involving children and adolescents aged 12 to 19 years with permanent dentition. The screening process, guided by the PRISMA guidelines and the Newcastle-Ottawa Scale for quality assessment, resulted in the inclusion of eight studies conducted across various global regions from 2013 to 2023. The analysis revealed that Vitamin D insufficiency and deficiency were prevalent among the study populations, ranging from 17.3% to 69.4%. Specifically, children and adolescents with Vitamin D insufficiency (<50 nmol/L) were found to have significantly higher odds of developing caries, with odds ratios (ORs) ranging from 1.13 to 2.57. Conversely, two studies indicated a protective effect of higher Vitamin D levels, with an OR of 0.80 and 0.59, respectively, for caries among children and adolescents with serum levels ≥ 50 nmol/L, suggesting an inverse relationship between Vitamin D status and caries risk. The results indicate both the protective role of adequate serum levels of Vitamin D above 20 ng/mL and the increased risk associated with insufficient levels below this threshold. However, the variations in study quality, methodologies and geographic settings underscore the challenges in drawing universal conclusions. Despite these limitations, our review suggests that improving Vitamin D status could be a beneficial component of preventive strategies against dental caries in children and adolescents, warranting further research to clarify the clinical significance of our findings.

Comprehensive Multidisciplinary Management of Bilateral Cleft Lip and Palate. Cureus 2024; 16:e52643. [PMID: 38380192 PMCID: PMC10876923 DOI: 10.7759/cureus.52643] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Accepted: 01/20/2024] [Indexed: 02/22/2024] Open
Abstract
Cleft lip and palate (CLP) represent a multifaceted congenital deformity encompassing skeletal, dental, and functional discrepancies. This case report presents the management of a 13-year-old female with bilateral CLP, focusing on the challenges associated with permanent dentition and retained deciduous teeth. The patient's history included prior lip and palate repair surgeries, leading to poor aesthetics and functional concerns. A multidisciplinary approach involving orthodontics, oral surgery, and prosthodontics was implemented. Clinical examinations revealed dental abnormalities, oro-nasal fistula, and skeletal discrepancies, necessitating a comprehensive treatment plan. The orthodontic intervention aimed at aligning the dentition, followed by surgical closure of the oro-nasal fistula and alveolar bone grafting (ABG) to facilitate permanent canine eruption. Prosthetic replacement of missing maxillary lateral incisors was accomplished, enhancing aesthetics with minimal invasiveness. Results demonstrated significant improvements in profile, dental alignment, and functional stability. Cephalometric and dental parameter analyses confirmed the corrections and enhancements achieved, affirming the success of the multidisciplinary treatment. This case report emphasizes the importance of a collaborative multidisciplinary approach in effectively addressing the complexities of bilateral CLP in patients with permanent dentition and retained deciduous teeth. The comprehensive treatment strategy rectified dental and skeletal issues and positively impacted the patient's overall well-being and self-confidence.

Experience, Prevalence, and Severity of Dental Caries in Mexican Preschool and School-Aged Children. Cureus 2023; 15:e51079. [PMID: 38269237 PMCID: PMC10806378 DOI: 10.7759/cureus.51079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/25/2023] [Indexed: 01/26/2024] Open
Abstract
Objective Dental caries in Mexico continues to be a public health problem, indicated by it is high prevalence and incidence in children. This disease is associated with pain in preschool and school children, with large-scale consequences for the individual, society, and health systems. The objective of the present study was to determine the experience (mean of caries indices), prevalence, and severity of caries in children 2-12 years of age who sought dental care at a dental school in Mexico. Material and methods A cross-sectional study was carried out on 826 clinical records of patients ages 2-12 years. The dependent variable was caries, in terms of experience (mean primary teeth (dmft) and permanent teeth (DMFT) indices), prevalence (dmft and DMFT greater than 0), and severity (cutoffs of caries indices at various levels). The independent variables were age and sex. The data were analyzed in Stata 14 (StataCorp LLC, College Station, Texas). Results The average age was 7.2±2.3; 52.4% were boys. In the primary dentition, the caries experience (mean dmft) was 3.01±3.30, the prevalence of caries was 65.8%, and the severity dmft>3=37.3% and dmft>6=15.6%. In the permanent dentition, the caries experience (mean DMFT) was 0.99±1.88, the prevalence of caries was 31.5%, and the severity DMFT>3=12.5% and DMFT>6=1.6%. The percentage of caries-free children in both dentitions was 26.1% (n=216/826). The experience, prevalence, and severity of caries were statistically different by age (p<0.001). Only in the severity of dmft>3 were differences observed across sex (p<0.05). Among children with mixed dentition, primary teeth were more affected than permanent teeth (2.46±2.87 vs 0.88±1.61; p<0.0001). Conclusions About seven out of 10 children were affected by cavities in either or both dentitions. It was observed that age was positively associated with dental caries, equally affecting girls and boys. In this sample, the primary dentition was impacted more than the permanent dentition. Despite being preventable, dental caries continues to be a health problem in children.

Dental Maturation in Two Groups of Children Born in 1969-1973 and 2005-2010. Dent J (Basel) 2023; 11:248. [PMID: 37999012 PMCID: PMC10670476 DOI: 10.3390/dj11110248] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Revised: 10/12/2023] [Accepted: 10/20/2023] [Indexed: 11/25/2023] Open
Abstract
This study compared differences in dental maturation and dental age in Scandinavian children born in 1969-1973 and 2005-2010. The study was based on 130 ethnic Scandinavian children, who were divided in two groups corresponding to the time periods and matched on age and sex. Each group consisted of 65 children (30 girls, 35 boys, mean age 9.29 years and 9.30 years, respectively). Dental maturation was analysed by orthopantomographs, in accordance with Demirjian and Haavikko. Dental age was analysed by orthopantomographs in accordance with Demirjian. Boys and girls were analysed separately by linear regression analysis adjusted for age. For the children born in 2005-2010, teeth matured significantly earlier (Demirjian: 0.21 maturities, CI 95% 0.11-0.31, p < 0.000. Haavikko: maxilla: 0.39 maturities, CI 95% 0.21-0.56, p < 0.000. Mandible: 0.42 maturities, CI 95% 0.17-0.67, p = 0.001) and the dental age was significantly higher (Demirjian: 6.04 months, CI 95% 0.23-0.77, p < 0.000) in comparison with the children born in 1969-1973. In conclusion, the teeth of Scandinavian children born 2005-2010 matured significantly earlier than those of children born in 1969-1973. The results may prove valuable in forensic dentistry, pedodontics, and for the timing of pedodontic and orthodontic treatment.

Evolution of the Terminal Plane from Deciduous to Mixed Dentition. CHILDREN (BASEL, SWITZERLAND) 2023; 10:1708. [PMID: 37892371 PMCID: PMC10605751 DOI: 10.3390/children10101708] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Revised: 10/17/2023] [Accepted: 10/18/2023] [Indexed: 10/29/2023]
Abstract
(1) Introduction: Correct development and growth of the dental arches and occlusion in the deciduous dentition is crucial for physiological occlusion in the permanent dentition. The present study evaluates the evolution of the terminal plane and canine occlusion class in the same children from deciduous to mixed dentition. (2) Materials and methods: The study included 257 children (164 girls and 93 boys) aged 3-5 years in the first phase and 8-10 years in the second phase. The chi-square test was used for the comparison of qualitative variables, while analysis of variance (ANOVA) or the Mann-Whitney U-test, Kruskal-Wallis test, and Wilcoxon test were used in the case of quantitative variables, as applicable. Statistical significance was considered for p < 0.05. (3) Results: The most common terminal plane in the first phase of the study was a bilateral flush plane (70%), followed by distal and mesial, with few differences between them. In the second phase, the most common terminal plane was mesial, followed by bilateral flush and distal. There were no statistically significant differences according to gender. Canine occlusion in the first phase was predominantly bilateral class I, followed by class II and class III. Similar results were recorded in the permanent dentition, except for a lesser percentage of children with canine class II. Molar occlusion in the second phase was predominantly class I, followed by half cusp class II and full cusp class II and class III. (4) Conclusions: The present study shows that knowing the age range in which maximum dental development and growth in both arches occurs may contribute to avoiding malocclusions and the possible need for orthodontic-orthopedic treatment, resulting in improved outcomes and greater stability.

Effectiveness of revitalization in treating apical periodontitis: A systematic review and meta-analysis. Int Endod J 2023; 56 Suppl 3:510-532. [PMID: 35579093 DOI: 10.1111/iej.13778] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Revised: 05/10/2022] [Accepted: 05/11/2022] [Indexed: 11/26/2022]
Abstract
BACKGROUND Revitalization procedures primarily aim to eliminate clinical symptoms and heal periapical lesions. OBJECTIVES The objective of the study was to elucidate the effectiveness of revitalization in treating apical periodontitis in necrotic mature and immature permanent teeth based on the following PICO question: In patients with permanent immature or mature teeth and pulp necrosis with or without signs of apical periodontitis (P) what is the effectiveness of revitalization (I) in comparison with calcium hydroxide apexification, apical plug and root canal treatment (C) in terms of tooth survival, pain, tenderness, swelling, need for medication (analgesics and antibiotics), radiographic evidence of reduction of apical lesion size, radiographic evidence of normal periodontal ligament space, radiographic evidence of increased root thickness and length (not for mature teeth), tooth function (fracture and restoration longevity), need for further intervention, adverse effects (including exacerbation, restoration integrity, allergy and discolouration), oral health-related quality of life (OHRQoL), presence of sinus tract and response to sensibility testing (O). (T) = Defined as a minimum of 1 year and maximum of as long as possible for all outcome measures, except 'pain, tenderness, swelling, need for medication (analgesics)', which is a minimum of 7 days and maximum of 3 months and OHRQoL which is minimum of 6 months and a maximum of as long as possible. METHODS Three databases (PubMed, Embase and Cochrane Library) were searched for human, experimental and observational studies in English, complemented with hand search, until 31/10/2021. Studies recruiting teeth with pulp necrosis (with/without apical periodontitis), with minimum 10 teeth/arm at the end of the study and with a follow-up of at least 1 year, were included. Records without an abstract and a full text were excluded. The qualitative analysis of the included (non-) randomized controlled clinical trials was performed with the Revised Cochrane risk-of-bias tools (RoB 2 and ROBINS-I). Meta-analysis for survival and success (including a subgroup analysis for mature/immature permanent teeth) was performed using the Mantel-Haenszel method. The certainty of evidence was assessed using GRADE (Grades of Recommendation, Assessment, Development and Evaluation). RESULTS From the 365 identified records, five met the inclusion criteria. The 12 months survival rate was 100% for all (im)mature permanent teeth in all groups (3 studies). The success rate at 12 months was 100% for immature permanent teeth for I and C (1 study), however, reduced to 92% and 80% for mature teeth in I and C respectively (1 study, p > .05). The risk of bias for the most critical outcome (survival) was high for two studies and low for one. For the critical outcome success, all assessed studies were highly biased. Meta-analyses provided pooled relative risk with no statistically significant difference between I and C for both survival (RR = 1.00, 95%CI = 0.96-1.04, p = 1.00) and success (RR = 1.06; 95%CI = 0.83-1.35, p = .66). The evidence level for survival was kept 'low' and for success was downgraded to 'very low' due to inconsistency and imprecision. DISCUSSION The survival and success rates were favourable in all included studies and for all groups; however, these outcomes are not reliable due to the low certainty level. Clinically, the most reported adverse event was tooth discolouration, hence the application of bismuth oxide containing calcium silicate cements should be avoided in revitalization. Radiographically, caution is needed when assessing periapical bone healing and further root development with periapical radiographs, due to multifactorial inaccuracies of this imaging technique. Methodological and assessment concerns need to be addressed in future clinical trials. Long-term results are necessary for studies reporting revitalization of mature permanent teeth, as they seem to be experimental so far. CONCLUSIONS No robust evidence was discovered to support that revitalization is effective to treat apical periodontitis in (im)mature permanent teeth. The success and survival rates of revitalized and fully pulpectomized (im)mature permanent teeth did not differ significantly. REGISTRATION Prospero: CRD42021262466.

Erosive Tooth Wear in Subjects with Normal Occlusion: A Pioneering Longitudinal Study up to the Age of 60. J Clin Med 2023; 12:6318. [PMID: 37834962 PMCID: PMC10573230 DOI: 10.3390/jcm12196318] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 09/23/2023] [Accepted: 09/29/2023] [Indexed: 10/15/2023] Open
Abstract
The aim of this study was to assess the erosive tooth wear (ETW) at early and mature adulthood in subjects with natural normal occlusion. The sample consisted of 23 untreated subjects with normal occlusion. Dental models were taken longitudinally from the same subjects at 13 (T0), 17 (T1) and 60.9 years of age (T2) at a university. Evaluation of ETW was performed using a modified Basic Erosive Wear Examination (BEWE) index. Interphase changes were evaluated using Friedman and Dunn's test. Ordinal logistic regression was used to assess the influence of sex, dental arch, tooth and dental surfaces on the erosive tooth wear. Linear regression was used to evaluate whether the ETW degree at T1 could discriminate the degree of ETW at T2. The significance level adopted was 5%. ETW showed a significant increase with aging. The median ETW index at T0, T1 and T2 was 2, 4 and 7, respectively. ETW was greater in males in the incisors and canines and on the incisal/occlusal and lingual tooth surfaces. No significant differences were found between the maxillary and mandibular arches. Subjects with severe ETW at mature adulthood had greater tooth wear at age 17. In conclusion, ETW significantly increased during aging in subjects with normal occlusion. The greater the degree of tooth wear at early adulthood, the greater the tooth wear at mature adulthood. Preventive care should be recommended during early adulthood in patients demonstrating erosive tooth wear in order to avoid worsening with aging.

Effect of two types of charcoal toothpaste on the enamel surface roughness of permanent teeth. Dent Res J (Isfahan) 2023; 20:98. [PMID: 38020261 PMCID: PMC10630542] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 04/30/2023] [Accepted: 06/06/2023] [Indexed: 12/01/2023] Open
Abstract
Background Charcoal in the composition of some kinds of toothpaste has created concerns regarding abrasiveness and subsequent complications. Considering the popularity of charcoal toothpaste, and the manufacturers' claims that no porosity is caused by activated carbon, this study aimed to compare the effects of two charcoal kinds of toothpaste and three conventional tubes of toothpaste on enamel surface roughness of permanent primary teeth. Materials and Methods This in vitro experimental study evaluated 75 teeth mounted in acrylic resin. Teeth were divided into five groups (n = 15). The primary surface roughness of teeth was measured by a profilometer. The teeth were then subjected to wear test in a V8 cross-brushing machine with Bencer and RP charcoal toothpaste, Crest 7, Colgate Optic White, and Bencer fresh mint toothpaste. After rinsing and drying specimens, their secondary surface roughness was measured. The mean changes in the roughness profile of specimens were analyzed by a one-sample Kolmogorov-Smirnov test at a 0.05 significance level. Results There was no significant difference in the mean surface roughness of specimens before and after the wear test (P > 0.05). The difference in the mean wear of five types of toothpaste was not significant either (P = 0.597). The mean changes in surface roughness were 0.0685 μm for Bencer charcoal, -0.0620 μm for RP charcoal, 0.0765 μm for Crest 7, 0.1137 μm for Colgate Optic White, and 0.1052 μm for Bencer fresh mint toothpaste. Conclusion Numerous kinds of toothpaste investigated in this study did not reveal any difference in terms of wear index; however, more studies are needed to evaluate the effectiveness and efficiency of these types of toothpaste.

Abstract
Supernumerary teeth form at an incidence of about 3% in the population, with differences among races and various clinical consequences. Information on detailed patterns, and especially on white subjects, is scarce in the literature. Therefore, we aimed to investigate the patterns of non-syndromic permanent supernumerary teeth in a white European population. A record review was performed in different orthodontic clinics and identified 207 eligible individuals with 258 supernumerary teeth. Approximately 80% of the subjects had one supernumerary tooth, while 15% had two. Supernumerary tooth formation was more often evident in males (male/female: 1.65). However, there was no sexual dimorphism in its severity. The following pattern sequences, with decreasing prevalence order, were observed in the maxilla: 21 > 11 > 12 > 18 > 28 and in the mandible: 34 > 44 > 35 > 45 > 42. Supernumerary teeth were most often unilaterally present, without sexual dimorphism. In the maxilla, they were more often anteriorly present, whereas in the mandible, an opposite tendency was observed. Supernumerary teeth were consistently more often observed in the maxilla than in the mandible; 74% were impacted, 80% had normal orientation (13% horizontal, 7% inverted), and 53% had normal size. The present thorough supernumerary tooth pattern assessment enables a better understanding of this condition with clinical, developmental, and evolutionary implications.

Abstract
The aims of this study were to develop a new classification for pre-eruptive intracoronal resorption(PIR) with different resorption areas and sizes and to compare the new classification scores among observers from different specialities and professional experience. The PIR was evaluated according to the new classification by two dentomaxillofacial radiologists and two endodontists. Information regarding the patient's age, gender, systemic diseases, the number of PIR, the affected tooth area and the size of the PIR was recorded. The new classification system showed that PIR six and seven defects were the most detected. Regarding jaw regions, the highest reliability was seen in the maxillary central teeth between observers I and IV, and maxillary premolar-molar teeth between observers II and III. This study revealed that PIR can be found in both root and crown dentine. Professional experience and specialty and awareness of the PIR defect may affect the diagnosis.

Abstract
The study aims to investigate and compare the success rate of concentrated growth factor (CGF) and blood clot (BC) as scaffolds in regenerative endodontic procedures (REPs). Immature permanent necrotic teeth treated by REPs with at least a 6-month follow-up were included. These teeth were divided into the CGF (53 teeth) and BC (68 teeth) groups. Treatment outcomes were assessed using a combined clinical and radiographic scoring system. The total success rate was 91.74% over a mean follow-up period of 23.15 months. There was no significant difference between the CGF group (86.79%) and BC group (95.59%). The success rate of traumatic teeth (84.31%) was significantly lower than that of teeth with developmental dental anomalies (98.39%) (p < 0.05). CGF may be a suitable alternative scaffold in REPs when adequate bleeding cannot be achieved. Moreover, compared to developmental dental anomalies, traumatic teeth treated by REPs may be more vulnerable to failure.

Time and sequence of the replacement of the deciduous by the permanent dentition in dogs and its applicability for age estimation. Anat Histol Embryol 2023; 52:460-489.

Abstract
This study investigated the influence of several covariates on the time and sequence of permanent dentition emergence following exfoliation of the deciduous teeth in puppies. The aim was to determine whether the emergence of permanent dentition can be used to assess whether a puppy that is traded across borders in the EU has reached the legally required minimum age of 15 weeks. The events were evaluated in a longitudinal study, with some cross-sectional observations, of 440 puppies belonging to 82 breeds. No significant differences were found between the left and right sides of a puppy's dentition nor between male and female puppies. Breed size and skull type had a significant impact: both the appearance and the completion of tooth eruption occurred considerably later in small or toy breeds and brachycephalic skull type breeds. The sequence of emergence differed little between maxillary or mandibular quadrants or between breeds. The first emerging elements were the maxillary first premolars or first incisors or the mandibular first incisors. The emergence of a permanent tooth usually occurred within 3 days before or after exfoliation of its precursor, except for the canines, which demonstrated a wider tooth replacement interval. This study presents standards for age assessment based on the emergence of permanent dentition for breeds of different sizes, using median ages or cumulative emergence percentages. However, the legal age determination of puppies with an assumed age of 15 weeks cannot be performed based on permanent dentition emergence, as this occurred at a later age in a large proportion of dogs (at least 95%) in our studied population. The probability of being at least 15 weeks old when at least one maxillary tooth has emerged was at least 72.25%, depending on breed size.

Dental Caries, Dental Erosion and Periodontal Disease in Children with Inflammatory Bowel Disease. Int J Med Sci 2023; 20:682-688. [PMID: 37082734 PMCID: PMC10110475 DOI: 10.7150/ijms.83075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Accepted: 03/28/2023] [Indexed: 04/22/2023] Open
Abstract
Background: There is reportedly a higher prevalence of dental caries and periodontal disease in adults with inflammatory bowel disease (IBD) than in healthy adults. Similar data for children are lacking in the literature. We aimed to evaluate the prevalence of dental erosion, dental caries, and periodontal disease in children with IBD. Methods: This was a cross-sectional comparative study. Using the established criteria of the World Health Organization, oral investigations and detailed questionnaires that covered nutritional habits were completed by the same pediatric dentist for 32 patients with IBD, aged 11 to 18 years (15.53 ± 2.00), and 32 healthy controls. Results: The decayed, missing, and filled tooth index showed no significant difference between the groups (p = 0.072). The frequency of consumption of salad, lemon gum, candy and sweetened milk was significantly higher in the control group (p = 0.041, 0.012, 0.001, and 0.001, respectively) than in the IBD group. No dental erosion was observed in the IBD group. Oral mucosal history determined that 20/32 patients with IBD (62.5%) had at least one oral extraintestinal manifestation. Despite no significant differences in plaque scores between the two groups, the gingival evaluation showed a much higher mean value of gingival index scores in the IBD group than in the control group (p = 0.003). Conclusion: Although the number of patients included in the study is small, we can conclude that oral extraintestinal manifestations and periodontal disease are more prevalent in paediatric patients with IBD than in healthy populations.

Developmental defects of enamel (DDEs) are widely observed in children and are related to the appearance of dental caries, malocclusion, tooth sensitivity, and unfavorable esthetic conditions. The objective of this cross-sectional study was to determine the prevalence and distribution of enamel defects present in children aged 6 to 12 years in the provinces located in southern Ecuador. A total of 1606 schoolchildren were examined under the World Health Organization criteria for diagnosis of DDEs. The results are presented using percentage frequency measures and chi-square associations. Some types of DDEs were presented by 50% of the schoolchildren, mainly diffuse opacity, with no statistical differences according to place of residence and/or environment, sex, and age (p > 0.05). In Ecuador, it is necessary to carry out studies on the factors that trigger enamel defects, since they may be associated with the high prevalence of caries already reported in other studies in the country.

Double facial talons on maxillary incisor-A rare case report and new proposed classification system. J Oral Maxillofac Pathol 2022; 26:423. [PMID: 36588837 PMCID: PMC9802516 DOI: 10.4103/jomfp.jomfp_43_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Revised: 05/09/2022] [Accepted: 05/10/2022] [Indexed: 01/03/2023] Open
Abstract
Background Double facial talon's cusp is a rare developmental anomaly affecting the deciduous or/and permanent dentition. The major complications associated with facial talons of maxillary incisors include poor esthetic appearance with increased susceptibility to caries and, sometimes, even soft tissue irritation, thereby needing early detection and precise management. Case Report We report a case of a 10 year-old female patient with a large double talon's cusp on the permanent left maxillary central incisor who presented with issues of soft tissue irritation and esthetic concern. One of the highlighting feature of this documented case was the difference in the extent of both talon's cusps on the facial surface of 21 teeth. As per Mayes' classification system, the talon towards the midline belonged to stage 2 and the talon away from the midline belonged to stage 3. Highlights Based on the previous literature search on classification systems, we intended to propose a new classification system for double facial talons depending on their size (equal/unequal) and presence of developmental grooves (separate or fused). The aim of this new classification system is to enlighten a new area of research that can be conducted on the treatment aspect by studying the difference in the structure of enamel rods, dentin, especially in case of double talons of unequal size (as the direction of enamel rods/dentinal tubules of the talons with that of the direction of enamel rods/dentinal tubules of the underlying tooth will vary) and their compatibility with choice of dental materials, to be used for proper adaptation and develop new treatment protocols of tooth preparation and restoration for such cases.

Collum angle of the anterior teeth: A systematic review and meta-analysis. J ESTHET RESTOR DENT 2022; 34:604-619. [PMID: 35156761 DOI: 10.1111/jerd.12886] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Revised: 01/24/2022] [Accepted: 01/27/2022] [Indexed: 11/30/2022]
Abstract
OBJECTIVES To assess and evaluate the collum angle (CA) of the anterior teeth of the permanent dentition. METHODS A search in seven databases for articles that had measured the CA in sagittal malocclusions was conducted until November 30, 2021. The risk of bias was assessed using the Modified Newcastle Ottawa scale. CA measurements using Cone Beam Computed Tomography or lateral cephalograms were included. The CA data were summarized by random-effects inverse generic meta-analyses. RESULTS Qualitative analysis of the 17 selected articles revealed that four were rated as "very good," 12 as "good" and 1 as "satisfactory." CA was 4.7° (95% CI of 3.1 to 6.4) and 2.0° (95% CI of 0.1 to 3.9) greater in Class II division 2 and Class III malocclusions respectively, than in Class I malocclusion cases. CONCLUSION Majority of the studies were rated as good or very good. Most studies evaluated the CA of the maxillary central incisors in Class II division 2 malocclusion. Studies assessing other maxillary anterior and mandibular anterior teeth are required. CLINICAL SIGNIFICANCE Practice of esthetic dentistry for teeth with increased CA is of clinical importance since the angle would determine the longevity and esthetic/cosmetic success of the rehabilitation. Placement of dental implants in areas of missing teeth with increased collum angle leads to excessive stress between the fixture and abutment leading to gingival recession. Thus, knowledge about the collum angle of anterior teeth and its variations in sagittal malocclusions would enable precise treatment planning in the field of esthetic dentistry.

Abstract
Regional odontodysplasia (RO), also called ghost teeth, is a rare nonhereditary developmental dental anomaly affecting the epidermal and mesenchymal tissues associated with the development of tooth which can affect both primary and permanent dentition. It can affect the child's overall quality of life and sometimes may lead to skeletal malocclusion. Management of such patients requires a multidisciplinary approach. Essix retainers are being widely used as retention appliances. Various modifications of this appliance are also being attempted. Thus, this article aims to focus on the use of Essix retainer as an interim prosthesis by modifying it with the incorporation of pontics to manage partial edentulousness and mild orthodontic corrections in a 7-year-old child diagnosed with bilateral RO.

Abstract
This case report out lines a rare complete intrusion of a permanent, maxillary central incisor (tooth 11) into the nasal cavity, with a late diagnosis and treatment. An eight-year-old boy was referred to an oral and maxillofacial surgery service with absence of tooth 11 after an episode of a fall from his own height. Approximately 50 days after the trauma, the patient presented, with a complaint of obstruction of the right nostril. The clinical examination and tomographic evaluation showed that the tooth had been intruded into the nasal cavity on the right side. The tooth in question was removed under general anesthesia by direct approach through the right nostril. The patient was followed up for approximately one year without complications. This case demonstrates the importance of a detailed evaluation during the first examination after intrusive luxation so the correct diagnosis is made and the correct treatment is performed to avoid greater morbidity and complications for the patient.

Abstract
Background and Aim Dental caries is one of the most common diseases seen in the oral cavity in all periods of deciduous, mixed, and permanent dentition. A comprehensive study of the oral microbiome is required to understand its polymicrobial etiology. The aim of this study was to reveal the plaque microbiome of caries-active and caries-free adults. Materials and Methods A total of 52 samples were collected from 26 caries-active patients and 26 caries-free controls. Dental supragingival plaque samples were collected from each subject and the bacterial 16S rDNA, expanded V3-V4 region, was amplified using next generation sequencing. Results The core microbiome was defined with 235 shared bacteria in genus level, and among all microbiome 14.8% of all bacteria showed significant difference (P < 0.05). The bacteria responsible of caries may be listed as Anaeroglobus, Atopobium, Bifidobacterium, Centipeda, Cryptobacterium, Desulfobulbus, Filifactor, Howardella, Lactobacillus, Leptotrichiaceae (unclassified), Megasphaera, Mycoplasma, Olsenella, Phocaeicola, Propionibacterium, Pseudoramibacter, Scardovia, Schwartzia, Treponema, and Veillonellaceae (unclassified). Conclusion The present study provides comprehensive knowledge of the microbiological etiology of caries in permanent dentition.

Dental trauma in primary dentition and the importance of its preservation until the eruption of permanent successor: a 6-year follow-up case report. INTERNATIONAL JOURNAL OF BURNS AND TRAUMA 2021; 11:424-429.

Abstract
Traumatic dental injuries (TDIs) are a public health concern that requires special attention in primary dentition due to the sequel that can be originated in permanent dentition. This paper aims to report a dental trauma injury highlighting the importance of follow-up the traumatized primary tooth until the eruption of its permanent successor. A 3-year-old female patient referred to a Dental Trauma Care Program (DTCP) in a Brazilian Public University after falling from her own height with the involvement of the deciduous maxillary left central incisor. The child's mother did not seek immediate care. The patient did not have any complaint and the tooth presented an enamel fracture during the clinical examination without radiographic alterations. The procedure performed was occlusal wear and insertion of the patient into the DTCP. After a 6-months clinical and radiographic follow-up, the primary maxillary left central incisor presented crown discoloration and periapical bone rarefaction. The treatment was pulpectomy followed by restoration of the tooth. In the 3-year follow-up, prolonged retention occurred and tooth extraction was the treatment of choice. After a 6-year follow-up, the permanent teeth erupted without any sequelae. TDIs are frequent in the primary dentition and, in some circumstances may interfere with the normal development of the permanent tooth causing irreversible sequelae. This case report reinforces the importance of seeking immediate care whenever dental traumas occur. Besides, a long-term follow-up of the traumatized tooth is essential for successful outcomes. Clinical and radiographic monitoring is fundamental to help dental professionals to decide the best treatment and to minimize potential complications.

Abstract
BACKGROUND Charcoal toothpastes can whiten teeth through abrasion. The purpose of this study was to determine the level of whitening and abrasiveness of charcoal toothpastes in permanent teeth. MATERIALS AND METHODS In this in vitro study, 30 premolars were polished, sectioned, mounted, and stored for 5 days in a coffee solution at 37°C. The color and surface profile of the teeth were measured by spectrophotometry and a profilometric device, respectively. The specimens were divided into 3 groups of 10 and were brushed 2000 times (equivalent to 3 times a day for 1.5 months) in a brushing machine using 20 g of each toothpaste (Bencer, Beverly, and Colgate) mixed with 40 ml of distilled water. The color and surface profile were remeasured. Bonferroni test and repeated measures analysis of variance (ANOVA) were used to examine the abrasion. One-way ANOVA was used to assess the whitening. RESULTS The three toothpastes caused changes in the surface profile (P = 0.0001). ΔE was equal to 3.3 (within the acceptable range) in all groups (95% confidence interval). There was no significant difference in abrasion (P > 0.05) and color change (P = 0.884) among toothpastes. CONCLUSION The results of this study showed that all the three used toothpastes have the abrasive and whitening effect on the samples significantly. The differences between the toothpastes were not significant.

Abstract
BACKGROUND Unlike many vertebrates with continuous dental replacement, mammals have a maximum of two dental generations. Due to the absence of dental replacement in the laboratory mouse, the mechanisms of the mammalian tooth replacement system are poorly known. In this study, we use the European rabbit as a model for mammalian tooth development and replacement. RESULTS We provide data on some key regulators of tooth development. We detected the presence of SOX2 in both the replacement dental lamina and the rudimentary successional dental lamina of unreplaced molars, indicating that SOX2 may not be sufficient to initiate and maintain tooth replacement. We showed that Shh does not seem to be directly involved in tooth replacement. The transient presence of the rudimentary successional dental lamina in the molar allowed us to identify genes that could be essential for the initiation or the maintenance of tooth replacement. Hence, the locations of Sostdc1, RUNX2, and LEF1 vary between the deciduous premolar, the replacement premolar, and the molar, indicating possible roles in tooth replacement. CONCLUSION According to our observations, initiation and the maintenance of tooth replacement correlate with the presence of LEF1+ cells and the absence of both mesenchymal RUNX2 and epithelial Sostdc1+ cells.

Abstract
Gemination is a morphologic anomaly of the tooth characterized by the formation of a macrodont. Bilateral presentation is rarely reported in permanent canines. Talon's cusp is an accessory cusp projecting lingually from the cingulum to the incisal edge and may be seen facially sometimes. Simultaneous occurrence of facial and lingual talons on the same tooth is rare. Concurrent occurrence of all the three entities has not been reported. These anomalies can cause unpleasant esthetic appearance due to irregular morphology. The presence of deep grooves on these teeth increases the susceptible to caries and periodontal disease requiring an endodontic intervention. Proper clinical and radiographic examination provides an accurate diagnosis and helps the clinician in the proper treatment planning and avoiding further complications. This article presents a unique case of simultaneous occurrence of bilateral gemination in the permanent maxillary canines with labial and palatal talon's cusps, which has not been reported in the literature till date.

Abstract
Objectives: Adequate gingival thickness provides a stable base for appropriate oral hygiene maintenance and mucogingival lesion prevention. The study aim was to assess attached gingiva thickness in relation to its width, probing depth, crowding, and tooth position in the arch during the early transitional dentition phase. Method and materials: A cross-sectional study in 193 children aged 7 years with healthy mucogingival complex was conducted, and PIROP ultrasonic biometer measurement of gingival thickness of mandibular incisors was applied. To compare qualitative variables across different dentition groups, chi-square test or Fisher exact test were used, and for quantitative variables Kruskal-Wallis test plus post-hoc analysis (Dunn test). Spearman correlation coefficient was used to correlate gingival thickness with width of attached gingiva, as well as Kruskal-Wallis test and post-hoc analysis to assess the relationship between gingival thickness and tooth position in the arch, type of incisor, and eruption phase. Results: The mean gingival thickness value was less than 1 mm in all incisor type groups. The thinnest gingiva was noticed at permanent newly erupted incisors (0.72 ± 0.36; P < .001). Thickness of attached gingiva positively correlated with its width and with probing depth (r = 0.164, P < .001). Gingival thickness was significantly thinner at incisors positioned labially. No correlation of attached gingiva thickness with transitional crowding in mandibular incisor segment was observed. Conclusions: The results revealed thin gingiva at mandibular incisors in white children during the early transitional dentition phase. Objective, ultrasound measurements were used for the first time in a pediatric population, and the device was simple and well tolerated.

Abstract
OBJECTIVE The purpose of this study was to determine the prevalence and clinical effect of untreated dental caries in Roma children from eastern Slovakia using dmft/DMFT index and SiC index, association between dental caries development and oral hygiene, dietary habits and preventive dental care. METHODS Dental caries were assessed by recording the dmft index (for primary dentition) and the DMFT index (for permanent dentition) that are used to assess the state of teeth, which expresses the current state of teeth or its development in an individual or the entire population. The SiC index was calculated as the mean dmft of one-third of the population with highest caries scores. The normality of data distribution was tested by Shapiro-Wilk test. P-value < 0.05 was considered statistically significant. Chi-square test was used to compare proportions (oral hygiene, dietary habits and preventive dental visit). Data were analysed using ordered logistic regression and t-test. The study includes questionnaire containing 5 questions about dietary habits, oral hygiene and preventive dental visit. RESULTS The results of presented study confirmed higher average values of DMFT (3.24) in the population of 12-year-old Roma children and lower average values of dmft (2.5) in the second group (p < 0.05). The value of SiC index represented 6.10 in the group of six-year-old and 7.66 in twelve-year-old children. Logistic regression was performed to test the magnitude of the association between dental caries and related factors. There was statistically significant association between average value dmft/DMFT and dietary habits, oral hygiene, and preventive dental visit in both study groups. CONCLUSION The study revealed insufficient oral hygiene of the Roma children population. Systematic implementation of preventive examinations for oral hygiene and health programmes are needed to promote oral health. The study represents a pilot study of the SiC index values in Roma minority population from eastern Slovakia.

Abstract
The long-term effects of secondhand smoke (SHS) on dental caries among Japanese young adults remain unclear. The purpose of this cross-sectional study was to evaluate whether household exposure to SHS is associated with dental caries in permanent dentition among Japanese young adults. The study sample included 1905 first-year university students (age range: 18–19 years) who answered a questionnaire and participated in oral examinations. The degree of household exposure to SHS was categorized into four levels according to the SHS duration: no experience (−), past, current SHS < 10 years, and current SHS ≥ 10 years. Dental caries are expressed as the total number of decayed, missing, and filled teeth (DMFT) score. The relationships between SHS and dental caries were determined by logistic regression analysis. DMFT scores (median (25th percentile, 75th percentile)) were significantly higher in the current SHS ≥ 10 years (median: 1.0 (0.0, 3.0)) than in the SHS—(median: 0.0 (0.0, 2.0)); p = 0.001). DMFT ≥ 1 was significantly associated with SHS ≥ 10 years (adjusted odds ratio: 1.50, 95% confidence interval: 1.20–1.87, p < 0.001). Long-term exposure to SHS (≥10 years) was associated with dental caries in permanent dentition among Japanese young adults.

Abstract
BACKGROUND/AIM Greek dentists are facing a new era of a globally continuous effort to improve the first-aid management and long-term treatment outcome of traumatic dental injuries (TDI). In Greece, where the basic and clinical research in the field of dental trauma has been limited until recently, assessing the attitudes and therapeutic strategies of Greek dentists for dental trauma is of great importance. The aim of this study was to evaluate the knowledge attitudes and therapeutic approaches of Greek dentists in different clinical scenarios of TDI. MATERIALS AND METHODS A cross-sectional study was conducted among 448 dentists. A questionnaire-based survey of demographic characteristics, attitudes, and a scenario-based knowledge test, of TDI, which was used to formulate a "Dental Trauma Knowledge Score" with a 0-8 score range, was administered. Mann-Whitney U tests (for two categories variables) and Kruskal-Wallis tests (for more than two categories variables) were performed. RESULTS The median knowledge score was 5.0 (IQR: 4-7), a level considered as "Acceptable." Knowledge scores were found to significantly differ by age group, with the younger dentists presenting the highest scores. Dentists with a self-evaluation as "Acceptable" had significantly higher scores. Most of the dentists would refer for CBCT in severe trauma cases. A significant association was found between younger ages and on awareness of the mobile application ToothSOS. Female dentists had significantly higher scores compared to males when asked about avulsion management. CONCLUSION An acceptable level of knowledge on TDI management was revealed among dentists in Greece. Higher knowledge scores were observed among younger dentists.

Abstract
BACKGROUND Dental erosion is the dissolution of dental hard tissues caused by acids of a non-bacterial origin. Dietary acids are considered the predominant and most controllable factor. AIM To synthesise the literature on the effects of dietary acids and habits on dental erosion in the permanent dentition of 10- to 19-year-old adolescents. MATERIALS AND METHODS An electronic literature search was undertaken in Cochrane, MEDLINE, CINAHL, Dentistry & Oral Sciences Source via EBSCOhost, and Embase with no restriction on the date of publication. RESULTS The initial search identified 449 articles, and 338 remained after removal of duplicates. Seventy-seven articles remained after screening of titles and abstracts, and 52 were eligible for the full-text review. A considerable variety of beverages, food, and dietary habits were reported as risk factors for dental erosion. The most consistent findings implicated the erosive potential of carbonated beverages and the consumption of acidic drinks at bedtime. CONCLUSIONS Although results were not consistent between cohort and cross-sectional studies, this review suggests certain dietary risk factors may contribute to dental erosion in adolescents. There is a need for more high-quality cohort studies to establish more conclusive evidence on the role of dietary acids and habits on dental erosion.

Abstract
BACKGROUND Dental trauma can determine the occurrence of sequelae in the deciduous tooth and due to the anatomical proximity to the germ of the successor permanent tooth, it frequently causes changes to the developing teeth. AIMS The objective of this study was to analyze clinically and radiographically traumatized primary teeth and permanent successors in children aged 0-8 years. MATERIALS AND METHODS Initially, a sample selection of medical records was made, designating the patients who fit the requirements; 247 patients were analyzed, totaling 379 traumatized primary teeth and 162 successive permanent teeth. STATISTICAL ANALYSIS The results were developed using the Proportion Test and the Chi-square test at the 5% significance level. RESULTS Injuries to hard tissue prevailed (57%), with emphasis on coronary enamel fracture (49.1%). After clinical and radiographic examinations, 78% of traumatized primary teeth maintained pulpal vitality. At the clinical evaluation, the frequency of the developmental disorders observed in permanent successors was 10.5%, with enamel hypocalcification being the most common sequela. 17.3% of the clinical changes in the successor permanent teeth were caused by trauma to the supporting tissue, with the intrusive dislocation being responsible for the largest number of damages (37.5%). CONCLUSION Based on the results found, it was concluded that the trauma occurring in the primary dentition were recorded and monitored more precisely and about the evaluated successive permanent teeth, except for the prevalence of sequelae found, the other factors are in agreement with the findings in the literature.

Abstract
INTRODUCTION The global objectives of WHO in the field of oral health by 2020 include the average intensity of caries among 12-year-old children no more than 1.5 by the DMFT index. In Samara the value of the DMFT among the adolescents at age 12 is 3.5. AIM To identify the appropriate timing for a launching of community-based schemes of dental caries prevention of permanent teeth for children of Samara. MATERIAL AND METHODS In a cross-sectoral multisample research from March to May 2017, the time of eruption and intensity of caries of the first permanent molars among children in Samara were studied. A total of 405 children aged 5 to 8, attending preschool and school educational institutions were examined. The quantity and the stage of eruption of the first permanent molars were assessed; the initial and manifest forms of caries were considered during the calculation of indexes of caries intensity of teeth and surfaces. RESULTS One to four first permanent molars were erupted among 26.3% of children aged 5, at an average 0.6±0.14 per one surveyed, the prevalence of caries of the first permanent molars was equal to 1.3%, including 1.3% of the initial carious defeats. In 6-year-old children - 65% had the first permanent molars, at an average of 2.38±0.199, and the prevalence of caries in these teeth was 29.63%, including initial forms of caries 27.16%. The results among 7-year-old children - 87.18% and 3.12±0.156, 60.3% and 51.28%, respectively. In 8-year-old children these figures were equal: 97.26%, 3.79±0.091, 68.49% and 60.27%, respectively. The rate of eruption of the first permanent molars and the prevalence of their carious lesions among girls was significantly higher than among boys. CONCLUSION The optimal age of children of Samara for inclusion in the regional programs of dental caries prevention is the age of 4 years - the age of the beginning of the first permanent molar eruption.

Abstract
To determine the treatment needs and the care index for dental caries in the primary dentition and permanent dentition of schoolchildren and to quantify the cost of care that would represent the treatment of dental caries in Mexico.A secondary analysis of data from the First National Caries Survey was conducted, which was a cross-sectional study conducted in the 32 states of Mexico. Based on dmft (average number of decayed, extracted, and filled teeth in the primary dentition) and DMFT (average number of decayed, extracted, and filled teeth in permanent dentition) information, a treatment needs index (TNI) and a caries care index (CI) were calculated.At age 6, the TNI for the primary dentition ranged from 81.7% to 99.5% and the CI ranged from 0.5% to 17.6%. In the permanent dentition, the TNI ranged from 58.8% to 100%, and the CI ranged from 0.0% to 41.2%. At age 12, the TNI ranged from 55.4% to 93.4%, and the CI ranged from 6.5% to 43.4%. At age 15, the TNI ranged from 50.4% to 98.4%, and the CI ranged from 1.4% to 48.3%. The total cost of treatment at 6 years of age was estimated to range from a purchasing power parity (PPP) of USD $49.1 to 287.7 million in the primary dentition, and from a PPP of USD $3.7 to 24 million in the permanent dentition. For the treatment of the permanent dentition of 12-year-olds, the PPP ranged from USD $13.3 to 85.4 million. The estimated cost of treatment of the permanent dentition of the 15-year-olds ranged from a PPP of USD $10.9 to 70.3 million. The total estimated cost of caries treatment ranged from a PPP of USD $77.1 to 499.6 million, depending on the type of treatment and provider (public or private).High percentages of TNI for dental caries and low CI values were observed. The estimated costs associated with the treatment for caries have an impact because they represent a considerable percentage of the total health expenditure in Mexico.

Abstract
PURPOSE This case report presents the management of molar incisor hypomineralization (MIH) from the mixed to the permanent dentition stage. Shortly after eruption of hypomineralized teeth, masticatory forces frequently cause rapid enamel breakdown. The MIH Treatment Need Index (MIH-TNI) provides guidelines for the treatment of MIH in relation to how severely the teeth are affected. Clinical considerations: An 11-year-old patient with permanent teeth affected by MIH was referred to us by his orthodontist for conservative dental treatment before planned orthodontic treatment. The restorative treatment varied according to the degree of severity of the affected teeth and included indirect composite resin restorations on teeth #17 (MIH-TNI 4c), #35 (MIH-TNI 4c) and #37 (MIH-TNI 4b), direct composite resin fillings on teeth #26 (MIH-TNI 2b), #27 (MIH-TNI 2a) and #16 (MIH-TNI 4c) and fissure sealants on teeth #16, 15, 14, 24, 25, 34, 36, 44, 45, 46 and 47. Orthodontic treatment was already started during the restorative phase with a bite-jumping appliance. With the conclusion of the second phase of mixed dentition at age 12, the orthodontist was able to start fixed orthodontic treatment of the maxillary and mandibular arches with all of the child's permanent teeth adequately restored. Orthodontic treatment was completed at age 14. At present, 6 years after initiation of dental treatment, all teeth are still free of decay. CONCLUSION A carefully supervised recall program with early comprehensive care at frequent intervals and adequate, defect-driven restorations depending on how severely the teeth are affected are the basis for a favorable long-term prognosis in patients with MIH.

The effect of pulp inflammation and premature extraction of primary molars on the successor permanent teeth. A retrospective study. Int J Paediatr Dent 2020; 30:18-26. [PMID: 31393632 PMCID: PMC7386925 DOI: 10.1111/ipd.12568] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2019] [Revised: 07/04/2019] [Accepted: 08/01/2019] [Indexed: 11/30/2022]
Abstract
BACKGROUND Untreated caries on primary molars often leads to pulp inflammation and extraction. AIM To retrospectively investigate the effect of pulp inflammation and extraction of primary molars on their successors regarding alignment in the dental arch and developmental enamel defects (DED). DESIGN The participants in this study were children at public schools in Petropolis (Brazil), who participated in a 3-year longitudinal clinical trial. Children (N = 44) were selected for the present study if they had at least one erupted premolar of which the predecessor primary molar presented pulp inflammation at baseline or during any of the 6-month follow-up assessments. All premolars were examined for DED and misalignment. Distinction was made between extraction performed before (E <8) or after the age of 8 years (E ≥8). Distinction was also made between pulp inflammation occurred before (P < 7) or after the age of 7 years (P ≥ 7). A logistic regression analysis was performed, and the odds ratio was calculated. RESULTS AND CONCLUSIONS Misalignment occurred more frequently in E <8 as compared to E ≥8 (OR = 2.85; P = .03). There was no significant difference in DED between P < 7 and P ≥ 7. CONCLUSION Misalignment of premolars occurs more frequently when the predecessor primary molars are extracted before the age of 8 years.

Tooth crown mesiodistal measurements for the determination of sexual dimorphism across a range of populations: A systematic review and meta-analysis. THE JOURNAL OF FORENSIC ODONTO-STOMATOLOGY 2019; 37:2-19. [PMID: 31187738 PMCID: PMC6875240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/09/2023]
Abstract
OBJECTIVE The aim of this study was to determine whether the tooth crown sexual dimorphism pattern reported in previous small studies can be generalized for a broader range of populations. LITERATURE REVIEW A systematic literature review was performed by two independent examiners. The following databases were searched from October 2015 to July 2016: PubMed, Scopus, Lilacs, ScienceDirect, Medline, and Cochrane Reviews. No language restrictions were applied to the search. SELECTION CRITERIA The inclusion criteria comprised original studies investigating mesiodistal permanent teeth that reported the sample population and standard deviation. All right-sided teeth, except the third molars, were measured and separated by sex in the included studies. Thirty-one studies were included in the quantitative data synthesis and meta-analysis. Studies of non-human teeth, skeletal remains, or an overly specific study population were excluded. MAIN RESULTS Thirty-one trials, involving 6481 participants, provided data for the meta-analysis of teeth. Sexual dimorphism in mesiodistal crowns was found in all teeth across a range of populations, principally in lower canines (5.73%) and maxillary canines (4.72%), followed by the lower second molars (3.54%) and upper second molars(3.20%), and finally in the lower first molars(3.14%) and upper first molars(2.64%). CONCLUSIONS A small degree of sexual dimorphism exists in all human teeth. Second molars and canines show the greatest sexual dimorphism. Additionally, smaller racial differences are present in mesiodistal crowns among groups living in different geographic areas; however, it is not possible to establish a single value applicable for all populations.

Is Adhesive Bond Strength Similar in Primary and Permanent Teeth? A Systematic Review and Meta-analysis. THE JOURNAL OF ADHESIVE DENTISTRY 2019; 20:87-97. [PMID: 29675511 DOI: 10.3290/j.jad.a40296] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 11/06/2022]
Abstract
PURPOSE To systematically review the literature on laboratory studies to determine whether the bond strength of adhesives to primary teeth is similar to that to permanent teeth. MATERIALS AND METHODS This systematic review was conducted according to PRISMA and registered in PROSPERO (CRD42014015160). A comprehensive literature search was conducted considering in vitro studies published up to June 2015 in the PubMed/MEDLINE database, with no limit on year of publication. Two reviewers independently selected papers, extracted data and assessed the risk of bias. From 422 eligible studies, 42 were fully analyzed. Thirty-seven studies were ultimately included in the systematic review and meta-analysis. A global comparison was performed with a random-effects model at a significance level of p < 0.05, expressed by the difference of means between the groups. The mean bond strengths and standard deviations were tabulated and statistical analyses were conducted in RevMan 5.1 (The Cochrane Collaboration). RESULTS There was a significant difference between groups, with permanent teeth presenting higher bond strength than primary teeth (p = 0.0005). When the enamel and dentin substrates were considered separately, dentin presented the same trend (p = 0.002), while for enamel there was no significant difference between the dentitions (p = 0.11). The majority of the studies had a high bias risk. CONCLUSION Adhesives have higher bond strengths when applied to permanent than to primary teeth. This difference was also valid when the comparison was made between permanent and primary dentin.

Ethnic differences in the root to crown ratios of the permanent dentition. Orthod Craniofac Res 2019; 22:99-104. [PMID: 30650237 DOI: 10.1111/ocr.12288] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2018] [Revised: 12/13/2018] [Accepted: 01/06/2019] [Indexed: 11/29/2022]
Abstract
OBJECTIVE Root resorption due to orthodontic tooth movement may adversely affect the root-crown (R/C) ratios of permanent teeth, especially in patients with Short Root Anomaly (SRA), a poorly understood disorder affecting root development. Evaluation of SRA R/C ratios to normal dentition would facilitate diagnosis and orthodontic treatment planning. However, reference values are not available for all ethnicities. Our goal was to determine R/C ratios of permanent teeth and their relationship to gender and ethnicity. SETTING/SAMPLE A retrospective study of 333 patients (109 Caucasians, 112 African Americans and 112 Hispanics) from the University of Alabama at Birmingham School of Dentistry. MATERIALS/METHODS Root lengths and crown heights were measured from panoramic radiographs of 6241 teeth using modified Lind's method. A linear mixed model was used to compare the R/C ratios of teeth among subgroups (gender, ethnicity). RESULTS The mean R/C ratios varied from 1.80 to 2.21 for the maxillary teeth and 1.83-2.49 for the mandibular teeth. Gender differences in R/C ratios were found to be significant only for the lower central incisors (P < 0.05). Hispanics showed significantly lower ratios for most teeth compared to the other two groups (P < 0.05). There were significant differences in R/C ratios between African Americans and Caucasians in the upper lateral incisors, lower central incisors and lower first premolars (P < 0.05). CONCLUSION Our results suggest that ethnicity is an important factor in determining the R/C ratios of permanent teeth. Therefore, when diagnosing developmental conditions such as SRA, ethnic group-specific reference values should be considered.

Abstract
BACKGROUND Dental caries is considered as one of the most serious dental diseases that results in localized dissolution and destruction of the calcified tooth tissues. As possible alternatives to conventional techniques of caries removal, chemomechanical caries removal systems have emerged. This study aims to clinically observe the advantages of chemomechanical method of caries removal over conventional technique. MATERIALS AND METHODS Inthis randomized controlled trial a total of 60 children with Class 1 open carious lesions were selected for the study. They were divided into two equal groups according to a method of caries removal (30 chemomechanical and 30 conventional on permanent molars). In Group A, caries was removed using the Carie-Care system and in Group B with the conventional drill and were restored equally with glass ionomer cement. The visual analogy face scale was used to determine the level of anxiety in children at baseline, during treatment and after treatment. RESULTS The results were subjected to statistical analysis using Student's unpaired t-test. It showed that though chemomechanical technique took a marginal increase in time compared to the conventional technique, it was found to be more comfortable for all the children. CONCLUSION Chemomechanical technique though time-consuming is definitely superior compared to the conventional technique provided we use a less technique sensitive restorative material which retains in the oral cavity for longer period. It is definitely a better treatment protocol in school-based dental treatment and atraumatic restorative dentistry compared to the conventional technique.

Membrane proteome characterization of periodontal ligament cell sets from deciduous and permanent teeth. J Periodontol 2018; 90:775-787. [PMID: 30499115 DOI: 10.1002/jper.18-0217] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2018] [Revised: 09/24/2018] [Accepted: 09/30/2018] [Indexed: 01/09/2023]
Abstract
BACKGROUND Physiological roles for the periodontal ligament (PDL) include tooth eruption and anchorage, force absorption, and provision of proprioceptive information. Despite the advances in understanding the biology of PDL cells, there is a lack of information regarding the molecular signature of deciduous (DecPDL) and permanent (PermPDL) PDL tissues. Thus, the present study was designed to characterize the membrane proteome of DecPDL and PermPDL cells. METHODS Primary PDL cells were obtained (n = 6) and a label-free quantitative proteome of cell membrane-enriched components was performed. Proteome findings were validated by quantitative polymerase chain reaction and Western blot assays in fresh human tissues (n = 8) and primary cell cultures (n = 6). In addition, confocal microscopy was used to verify the expression of target factors in the PDL cell cultures. RESULTS Comparative gene ontology enrichment analysis evidenced that most stickling differences involved "endomembrane system" (PICALM, STX4, and LRP10), "hydrolase activity" (NCSTN and XRCC6), "protein binding" (PICALM, STX4, GPNMB, VASP, extended-synaptotagmin 2 [ESYT2], and leucine-rich repeat containing 15 [LRRC15]), and "isomerase activity" (FKBP8). Data are available via ProteomeXchange with identifier PXD010226. At the transcript level, high PICALM in DecPDL and ESYT2 and LRRC15 in PermPDL were confirmed in fresh PDL tissues. Furthermore, Western blot analysis confirmed increased levels of PICALM, LRRC15, and ESYT2 in cells and/or fresh tissues, and confocal microscopy confirmed the trends for PICALM and LRRC15 expression in PDL cells. CONCLUSION We report the first comprehensive characterization of the membrane protein machinery of DecPDL and PermPDL cells, and together, we identified a distinct molecular signature for these cell populations, including unique proteins for DecPDL and PermPDL.

Abstract
INTRODUCTION The aims were: evaluation of the correlation between the Dental Aesthetic Index (DAI) and Index of Complexity, Outcome and Need (ICON); the assessment of orthodontic treatment need for schoolchildren in a population with two indices, separately for schoolchildren with mixed and permanent dentition; the estimation of the population share that could not receive orthodontic treatment because of the presence of caries and/or gingivitis. METHODS A total of 2652 Zagreb school children (7 - 19 years old, 52.4% of them were females) completed a questionnaire regarding previous orthodontic treatment and the type of appliance used. Their oral cavity was also inspected. The DAI and ICON indices were used for the assessment of malocclusion prevalence. RESULTS The subjects with mixed dentition had a greater need for orthodontic treatment, when compared to subjects with permanent dentition, when using the DAI index (p<0.001). When using the ICON index, 11.7% of subjects with mixed dentition had very severe malocclusion, as opposed to 5.8% of subjects with permanent dentition. The DAI and ICON scores correlated positively linearly (r=0.521; p<0.001). A higher prevalence of both gingivitis and caries was recorded more often in boys; caries more often in the group with the mixed dentition, and gingivitis in the group with permanent dentition (p<0.05). CONCLUSION The DAI and ICON indices have moderate agreement in assessment of malocclusion severity scores. One third of all schoolchildren with various degrees of both ICON and DAI indices have gingivitis, and half of them have caries.

Abstract
Although a link between dietary changes, caries, and dental development has been observed, the literature provides little insight about this relationship. The aim of our study was to investigate the association between dental caries and dental development in a clinical sample of Albanian children and adolescents. In total, 118 children and adolescents, born between 1995 and 2004 and aged 6-15 years, were included. Dental caries in the deciduous dentition was assessed using the Decayed, Filled Teeth (dft) index and dental caries in the permanent dentition was assessed using the Decayed, Missing, Filled Teeth (DMFT) index. Dental development during the permanent dentition was determined using the Demirjian method. Linear and ordinal regression models were applied to analyze the associations of dental caries with dental age and developmental stages of each left mandibular tooth. Dental caries in the deciduous dentition, estimated as a median dft of 2.0 (90% range, 0.0-9.1), was significantly associated with lower dental age (β = -0.21; 90% CI: -0.29, -0.12) and with delayed development of the canine, both premolars, and the second molar. Untreated dental caries (dt) was associated with lower dental age (β = -0.19; 90% CI: -0.28, -0.10). Dental caries in the permanent dentition, estimated as a median DMFT of 1.0 (90% range, 0.0-8.0), was not significantly associated with dental age (β = 0.05; 90% CI: -0.04, 0.14). However, the DMFT was associated with the advanced stages of development of both premolars and the second molar. The untreated dental caries in the deciduous dentition delays the development of permanent teeth.

Abstract
Objectives Recent literature suggested that higher vitamin D concentrations in childhood are associated with a lower prevalence of molar incisor hypomineralization (MIH). As tooth development already starts in utero, we aimed to study whether vitamin D status during foetal, postnatal and childhood periods is associated with the presence of hypomineralized second primary molars (HSPMs) and/or MIH at the age of six. Methods Our study was embedded in the Generation R Study, a population‐based, prospective cohort from foetal life onwards in Rotterdam, the Netherlands. HSPMs and MIH were scored from intraoral photographs of the children at their age of six. Serum 25(OH)D concentrations were measured at three points in time, which resulted in three different samples; mid‐gestational in mothers’ blood (n = 4750), in umbilical cord blood (n = 3406) and in children's blood at the age of 6 years (n = 3983). Results The children had a mean (±SD) age of 6.2 (±0.5) years at the moment of taking the intraoral photographs. After adjustment for confounders, no association was found between foetal 25(OH)D concentrations and the presence of HSPMs (OR 1.02 per 10 nmol/L higher 25(OH)D, 95% CI: 0.98‐1.07) or MIH (OR 1.05 per 10 nmol/L increase, 95% CI: 0.98‐1.12) in 6‐year‐olds. A higher 25(OH)D concentration in umbilical cord blood resulted in neither lower odds of having HSPM (OR 1.05, 95% CI: 0.98‐1.13) nor lower odds of having MIH (OR 0.95, 95% CI: 0.84‐1.07) by the age of six. Finally, we did not find higher 25(OH)D concentrations at the age of six to be associated with a significant change in the odds of having HSPM (OR 0.97, 95% CI: 0.92‐1.02) or MIH (OR 1.07, 95% CI: 0.98‐1.16). Conclusions 25(OH)D concentrations in prenatal, early postnatal and later postnatal life are not associated with the presence of HPSMs or with MIH at the age of six. Future observational research is required to replicate our findings. Furthermore, it is encouraged to focus on identifying other modifiable risk factors, because prevention of hypomineralization is possible only if the causes are known.

Abstract
Background. Stem cells have contributed to the development of tissue-engineered-based regenerative periodontal therapies. In order to find the best stem cell sources for such therapies, the biologic properties of stem cells isolated from periodontal ligaments (PDL) of deciduous (DePDLSC) and permanent (PePDLSC) teeth were comparatively evaluated. Methods. PDL stem cells were isolated from six sound fully erupted premolars and six deciduous canines of healthy subjects. In vitro biologic characteristics such as colony formation, viability, stem cell marker identification and osteogenic differentiation (using alkaline phosphatase analysis and Alizarin red staining) were comparatively assessed using one-way ANOVA and post hoc Tukey tests using SPSS 13.0. Results. Stem cell populations isolated from both groups were CD105+ and CD90+ and CD45‒. No statistically significant differences were found in stem cell markers, colony formation and viability. Both groups were capable of osteogenic differentiation. However, alkaline phosphatase activity test showed a statistically significant difference, with PePDLSC exhibiting higher alkaline phosphatase activity (P=0.000). No statistically significant difference was seen in quantitative alizarine red staining (P=0.559). Conclusion. Mesenchymal stem cells of PDL could successfully be isolated from permanent and deciduous teeth. A minor difference was observed in the osteogenic properties of the two cell types, which might affect their future clinical applications.

Abstract
In the case reports, two different approaches have been described to treat the developmental disturbances in the maxillary central incisors due to trauma to its predecessor. The treatment plan was chosen according to the type and severity of the malformations, the exact location and the morphology of the involved teeth. In the first case, the disimpaction of the maxillary right central incisor was achieved with the combined of surgical and orthodontic therapy, that was planned in two consecutive stages. In the second case the severe root angulation and the failure of the previous orthodontic traction made impossible the repositioning of the upper right central incisor, which was surgical removed.

Abstract
Objective: The aim of this research project was to determine whether the sizes of the first molars allow clinicians to achieve the first goal of an ideal clinical outcome. Material and Methods: Seventy-eight sets of dental casts that have been presented to the American Board of Orthodontics were evaluated. A Boley gauge was used to measure the length from the mesiobuccal cusp to the distobuccal cusp of the maxillary first molar and the length from the mesiobuccal groove of the mandibular first molar to the occlusal embrasure between the mandibular first and second molars. These two measurements were taken on both sides of each set of dental casts for a total of four measurements per set. Results: The maxillary measurements ranged from 3.6 to 6.9 mm with an average of 5.2 mm. The mandibular measurements ranged from 5.0 to 8.0 mm with an average of 6.5 mm. The data were tested for normality and found to be equally distributed. A t-test revealed significant differences in tooth sizes between maxillary and mandibular first molars on both sides. On average, the mesiodistal length measured on maxillary first molars was about 80% of that of their mandibular counterparts. Only 5 of the 78 sets of dental casts evaluated had equal maxillary and mandibular measurements on one side (either left or right), and none of them had equal measurements on both sides. Conclusion: Clinicians have to understand that tooth size discrepancies do exist in patients and that these discrepancies make the completion of a perfect case challenging.

Abstract
Although children with oral clefts have a higher risk for dental anomalies when compared with the general population, prior studies have shown conflicting results regarding their dental decay risk. Also, few studies have assessed dental decay risk in unaffected relatives of children with clefts. Thus, the question of increased risk of dental decay in individuals with oral clefts or their unaffected relatives is still open for empirical investigation. This study characterizes dental decay in the largest international cohort to date of children with nonsyndromic clefts and their relatives, as compared with controls, and it addresses whether families with oral clefts have a significantly increased risk for dental decay versus the general population. A total of 3,326 subjects were included: 639 case probands, 1,549 unaffected relatives, and 1,138 controls. Decay was identified from in-person dental examinations or intraoral photographs. Case-control differences were tested with regression analysis. No significant differences were shown in percentage decayed and filled teeth and decayed teeth in the primary dentition (dft, dt) and permanent dentition (DFT, DT) in cases versus controls. In the cleft region, no significant differences were seen in primary or permanent decay (dt, DT) when compared with controls. No difference was found with regard to cleft type and percentage dft, dt, DFT, and DT in case probands. Nonsignificant differences were found in unaffected siblings and parents versus controls (primary and permanent dentitions). Collectively, these findings indicate that individuals with nonsyndromic oral clefts and their families do not have a higher dental decay risk as compared with the general population. These results suggest that either genetic or environmental factors underlying a higher susceptibility for dental anomalies do not increase caries risk or that the seemingly higher risk for dental decay associated with increased dental anomalies in case probands may be superseded by possible greater access to dental care.

Salivary Immunoglobulin Gene Expression in Patients with Caries. Open Access Maced J Med Sci 2017; 5:236-243. [PMID: 28507635 PMCID: PMC5420781 DOI: 10.3889/oamjms.2017.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2017] [Revised: 01/14/2017] [Accepted: 02/07/2017] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND: Immunoglobulins mediate the host’s humoral immune response are expressed in saliva. AIM: To quantify the FcαR, FcγRIIB, and FcαμR gene expression in the saliva of Mexican patients with caries in mixed and permanent dentition. SUBJECTS AND METHODS: This was a comparative cross-sectional study. mRNA was isolated from 200 μL of saliva following the RNA III Tissue Fresh-frozen protocol of the MagNA Pure LC Instrument 2.0 (Roche Diagnostics GmbH, Nederland BV) and the FcαR, FcαμR and FcγRIIB were quantified through TaqMan Assays. RESULTS: One hundred individuals, 50 with mixed dentition and 50 with permanent dentition, were included in the study. Statistically, it was found a significant difference (p = 0.025) in the IgG (FcγRIIB) expression between the studied groups. CONCLUSION: Although we confirmed the existence of FcαR, FcγRIIB and FcαμR gene expression in saliva, only a significant difference in the expression of FcγRIIB between the mixed dentition and permanent dentition was found.

Abstract
The aim of this study was to examine the association between the bone mass (bone mineral content [BMC]) and hypomineralized second primary molars (HSPMs)/molar incisor hypomineralization (MIH) in 6-y-old children. This cross-sectional study was embedded in the Generation R Study, a population-based prospective cohort study, starting from fetal life until adulthood in Rotterdam, Netherlands. The European Academy of Pediatric Dentistry criteria were used to score the intraoral photographs on the presence or absence of HSPMs and MIH. Bone mass was measured with a dual-energy x-ray absorptiometry (DXA) scan. Intraoral photographs and DXA scans were available in 6,510 6-y-old children. Binary logistic regression models were used to study the association between the bone mass and HSPMs/MIH. In total, 5,586 children had their second primary molars assessed and a DXA scan made; 507 children were diagnosed with HSPM. Of 2,370 children with data on their permanent first molars, 203 were diagnosed with MIH. In the fully adjusted model, children with lower BMC (corrected for bone area) were more likely to have HSPMs (odds ratio, 1.13; 95% confidence interval, 1.02 to 1.26 per 1-standard deviation decrease). A lower BMC (corrected for bone area) was not associated with MIH (odds ratio, 1.02; 95% confidence interval, 0.87 to 1.20 per 1-standard deviation decrease). We observed a negative association between BMC (corrected for bone area) and HSPMs. No association was found between BMC (corrected for bone area) and MIH. Future research should focus on investigating the mechanism underlying the negative association between the bone mass and HSPMs. Our study, in a large population of 6-y-old children, adds the finding that BMC (corrected for bone size) is associated with HSPMs but not with MIH in childhood.

Abstract
Aim: The purpose of this retrospective study was to determine the prevalence of hypodontia and to ascertain the need of interdisciplinary treatment for ensuing esthetic and functional problems in a target population of Al-Jouf Province, Saudi Arabia. Subjects and Methods: Using a dental administration software tool, a total of 1267 patients who presented to the outpatient clinics of the Orthodontic and Prosthodontic Departments between March 2015 and January 2016 were identified. Of those, 694 were females and 573 were males. All permanent teeth were investigated, except third molars. Results: The prevalence of hypodontia was 6.1%. The difference between genders was not statistically significant (P = 0.597) although female hypodontia prevalence was higher than males (6.6% and 5.5%, respectively). The majority of patients had one or two missing teeth. There were no significant differences between right and left sides for any particular tooth. The most commonly missing teeth were mandibular second premolar (40.1%), followed by the maxillary lateral incisor (20.4%) and then the maxillary second premolars (12.6%). Conclusions: The prevalence of hypodontia in Al-Jouf Province, Saudi Arabia, was within the average values portrayed in the majority of the published literature. The majority of affected individuals had one or two missing teeth. None of the patients examined had more than four missing teeth. There were no significant differences in the distribution of hypodontia between the affected jaws according to gender. Although less prevalent, considerable cases of bilateral missing teeth were found in the present study which necessitates the need for urgent interdisciplinary intervention and management.

Restoring crown fractures by direct composite layering using transparent strip crowns. Dent Traumatol 2015; 32:156-60. [PMID: 26450763 DOI: 10.1111/edt.12233] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/09/2015] [Indexed: 11/27/2022]
Abstract
Traumatic dental injuries are mostly seen at childhood and adolescence. The most common fracture in permanent anterior teeth is crown fracture. Esthetic and easy rehabilitation of these anterior teeth is possible using layering techniques and direct composite resin restorations. Shape, color and surface texture are the most important factors in restoring crown fractures esthetically. This article illustrates how to perform an esthetic composite resin restoration of crown fractures using strip crowns. The technique suggests using a strip crown as a mold for direct resin composite restoration. This provides a cost-effective treatment with operator friendly approach where most outstanding advantage is the minimum chair-side time with a single visit that is very important for young trauma patients.

Root Resorption a 6-Year Follow-up Case Report. Open Dent J 2015; 9:103-5. [PMID: 25870717 PMCID: PMC4391216 DOI: 10.2174/1874210601509010103] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2014] [Revised: 02/20/2015] [Accepted: 02/26/2015] [Indexed: 11/22/2022] Open
Abstract
This paper describes the clinical course of a pediatric patient developing cervical external root resorption (CERR). An 11-year old male patient had sustained dental trauma and was diagnosed with crown fracture affecting the incisal and middle thirds of the maxillary right permanent central incisor and the maxillary right permanent lateral incisor with pulp exposure and CERR after 24 months. Diagnosis and treatment of CERR are a challenge for dental practitioners. In this case, preservation of natural dentition is shown as a successful treatment in a 6-year follow-up.
