[PMID: 37960738 PMCID: PMC10637491 DOI: 10.1097/md.0000000000035750] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Accepted: 10/02/2023] [Indexed: 11/15/2023] Open
Abstract
The aim of this study was to analyze the causes, clinical characteristics, social factors, and current status of treatment of traumatic dental injury (TDI) in the primary dentition. A retrospective analysis was performed on 144 children (213 teeth) with TDI in the primary dentition from our hospital between December 2017 and June 2020. Data were analyzed using the chi-square test and the Mann-Withney-Wilcoxon test. Boys accounted for 68.1% (98/144) and girls for 31.9% (46/144) of all 144 children with TDI in the primary dentition, with a boy-girl ratio of 2.13:1. The primary age of TDI in deciduous teeth was 2 to 4 years old, accounting for 59% of all cases. Collision with others and fall were the 2 main causes of trauma to the deciduous teeth, making up 52.1% and 44.4% of all causes, respectively. Crown fracture injury was the most common type of TDI in the primary dentition, accounting for 37% of all cases (53/144). Of the 144 cases, 17.4% (25/144) was accompanied by soft tissue laceration, while 22.2% (32/144) by swelling or contusion of tissue. Maxillary teeth (92.4%) were more vulnerable to injury than mandibular teeth (7.5%), with maxillary incisor being the most vulnerable 1 (91.5%). The percentage of children arrived at the hospital for treatment 24 hours after the injury was the highest (57.0%, 82/144). After the hospital visit, 74.3% of children received treatment for the dental trauma. In terms of the treatment modalities, extraction of the traumatized teeth (27.1%) and pulpectomy + resin filling (or preformed crown) restoration were predominant. Approximately 28.5% (41/144) of cases were reviewed within 2 years, with the proportion of children with pulpitis or periapical infection being the highest (29.3%, 12/41). Age, gender, collision, and fall are the factors linked to a higher risk of TDI in the primary dentition in children under the age of 7. Resin filling (or preformed crown) restoration and pulpectomy are effective in preserving the affected tooth and controlling infection. However, the preservation of the affected tooth and the prevention of infection may be hampered by late visits and low follow-up rates.

Abstract
This study was performed to report the dental abnormalities encountered in immature dogs with a history of mandibular fracture. Dogs were included in the study if mandibular fractures were diagnosed by means of oral examination and diagnostic imaging, they were treated with non-invasive or minimally invasive methods, and there was a follow-up examination of at least 90 days after the initial presentation with the last follow-up visit occurring at 6 months of age or older. Eleven dogs met the inclusion criteria. Dental abnormalities occurred exclusively in those dogs that had sustained fracture of the mandibular body or fracture at the transition of mandibular body and mandibular ramus. A high number of developing permanent teeth located in or near the mandibular fracture were affected (73.5%). The most common dental abnormalities were failure of eruption or partial eruption (29.0%), resorption (22.6%), abnormal shape (19.4%), and enamel hypoplasia (16.1%). The majority of deciduous teeth (64.3%) in or near the mandibular fracture exfoliated uneventfully. Ten out of 11 dogs needed a surgical procedure to treat dental abnormalities after mandibular fracture healing. The development of the tooth germs located in or near a mandibular fracture is frequently affected. Radiographic evaluation of the area of trauma is recommended until eruption and full development of the teeth are completed.

Factors Involved in the Perception of Enamel Dyschromic Lesions-A Questionnaire-Based Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19020900. [PMID: 35055723 PMCID: PMC8775837 DOI: 10.3390/ijerph19020900] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/18/2021] [Revised: 01/11/2022] [Accepted: 01/12/2022] [Indexed: 11/24/2022]
Abstract
Dyschromic lesions (DLs) of tooth enamel are common disorders, with multiple etiologies and various clinical forms, that raise public health concerns. This study aimed to determine the factors that influence the perception of DLs and to assess the perceived need for dental treatment in various clinical cases. A paper-based questionnaire with attached images of frontal teeth exhibiting different DLs was distributed to patients, dental students, and dentists. A total of 383 volunteers participated in this study, and their answers were statistically described and analyzed. This study found that in cases with multiple, well-demarcated areas of opacities associated with diffuse opacities on neighboring teeth, most respondents noticed and reported only the most severe lesions, disregarding the minor ones. The contrast of the lesion with the color of the substrate influenced the overall perception and a significant correlation between these two variables was found. However, the color of the DLs did not significantly impact the overall perception of the lesions. A higher overall perception of DLs was significantly correlated with a favorable opinion regarding the need for treatment. Furthermore, gender and medical background were significantly associated with the overall perception of DLs.

Developmental Dental Defects in Permanent Teeth Resulting from Trauma in Primary Dentition: A Systematic Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19020754. [PMID: 35055575 PMCID: PMC8775964 DOI: 10.3390/ijerph19020754] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Revised: 01/04/2022] [Accepted: 01/07/2022] [Indexed: 01/27/2023]
Abstract
The objective was to determine whether trauma in primary dentition causes alterations in the development of permanent dentition. Searches were made in May 2020 using PubMed, MEDLINE, MEDES, Scopus, Lilacs, and Embase. Papers in English, German, and Spanish, without restrictions in the year of publication, were included. The quality of the studies was analyzed using the NOS Scale. The search retrieved 537 references, and seven studies were included for a qualitative analysis. The results showed that trauma to a deciduous tooth can damage the bud of the permanent tooth. Enamel discoloration and/or hypoplasia were the most common sequelae in the permanent teeth after trauma to the primary predecessor. The type and severity of sequelae in the permanent tooth are associated with the development phase of the bud. Children with trauma of their primary teeth should receive checkups until the eruption of the permanent teeth for the early diagnosis and treatment of possible sequelae. Intrusion of the primary tooth was the trauma that caused the most damage and enamel alterations the most frequent sequelae.

Abstract
OBJECTIVES The aim of this study was to retrospectively identify the prevalence, patterns, and accident types of traumatic dental injuries (TDIs) in children with primary teeth in Vienna, Austria. MATERIAL AND METHODS The investigation was conducted as a retrospective overview study including all children with TDIs in primary teeth at the University Dental Clinic of Vienna (Austria) between 2014 and 2016. Dental records including age, gender, location of trauma, type of trauma, cause of TDI, and location of traumatic incident were obtained. Furthermore, the time of presentation and the time span between TDI and initial treatment were evaluated. RESULTS The sample comprised TDIs in 243 patients with 403 primary teeth. In a ratio of 1:1.45, boys were significantly more involved than girls. Upper central and lateral incisors were most frequently affected (n = 371, 92.1%). Dislocations were the most common type of injury (n = 298, 74%) with subluxations being the most prevalent form (n = 85, 28.5%). In 23% (n = 92), fractures were observed. The majority of traumatic incidents occurred at home (88.5%). CONCLUSION The injury characteristics are comparable to what has previously been reported in other studies in pediatric populations. CLINICAL RELEVANCE TDIs are a prevalent event in children worldwide and incisors are the most affected teeth in the primary dentition. Thus, dental practitioners should be able to handle these injuries.

Abstract
BACKGROUND/AIM Dental trauma is a highly prevalent problem worldwide. The aim of this study was to describe characteristics of trauma to anterior primary teeth and its sequelae for primary and successor teeth over a 10-year period of assistance at the paediatric dental traumatology clinic in the State University of Rio de Janeiro, Brazil. MATERIALS AND METHODS The data were obtained from the dental records of children assisted from 2006 to 2016. Inclusion criteria were trauma to anterior primary teeth; aged <1 to 9 years at the time of trauma; and at least one follow-up appointment. The data concerning traumatized teeth, child's age, soft tissue injuries, types of traumatic dental injuries and sequelae in both dentitions were collected. RESULTS Of the 1230 dental records, 483 (39.3%) were eligible, consisting of 815 teeth. The mean age at the time of trauma was 37.4 months (239 males and 244 females). The most important characteristics were: tooth 51 was most affected; falls, at home, on a ceramic floor, were the main cause; gingival laceration, enamel fracture and intrusive luxation were the most frequent types of trauma; premature tooth loss of primary teeth and enamel discoloration in their successor were the most frequent sequelae; and injuries in the periodontal tissue were demonstrated as the highest risk for sequelae in successors (OR, 3.798; p< 0.001). CONCLUSIONS Most traumatic injuries occur in young children, in their home environment. Consequences for the primary teeth were more frequent compared to the permanent successor tooth. Traumatized primary teeth involving periodontal tissue have more chances to result in sequelae to their successor teeth.

Abstract
BACKGROUND/AIMS Traumatic dental injuries (TDIs) in the primary dentition are a significant public health problem, which has been neglected worldwide. Despite its high prevalence, limited studies address this injury. The aim of this study was to determine the characteristics and treatment modalities of TDIs affecting primary teeth, along with accompanying medical co-morbidities and attendance at follow-up appointments. MATERIAL AND METHODS This retrospective analysis included all TDIs affecting primary teeth from January 2014 to January 2017. Data abstraction included demographics, time lapse prior to arrival at hospital, trauma etiology, classification of TDIs, soft tissue and supporting bone injuries, medical co-morbidities, emergency treatment, follow-up appointments and prognosis. RESULTS Records of 283 children with 536 traumatized primary teeth were reviewed. The median age was 2 years and the maxillary right central incisor (35.1%) was the most frequently injured tooth. Almost half the patients, 46.3%, sought treatment after 24 h. Periodontal tissue injuries (97.2%) predominated TDIs for which fall accidents (82.0%) were the most encountered cause. Most patients (177/283) had accompanying soft tissue/supporting bone injuries and 67.2% had multiple traumatized teeth. Seventy percent of the patients were examined only or were prescribed medication. Survival time following TDIs was unknown in 67.7% of traumatized teeth due to non-attendance at follow-up appointments. Most patients (55.1%) did not attend the follow-up appointments. CONCLUSIONS TDIs occurred in the primary dentition with the predominance of periodontal tissue injuries. When TDI was the presenting problem to hospital, accompanying systemic injury was rare. Treatment modalities were mostly limited to examination or extraction. The follow-up appointments were poorly attended.

Abstract
White spot lesions on teeth present as white opacities due to enamel surface and/or subsurface demineralisation. Unfortunately, dentistry has seen a marked jump in prevalence and severity of white spot lesions over the past decade. In response to the rise in white spot lesions, the dental industry has been pushed to create less invasive alternatives for the removal of these lesions, particularly when located anteriorly. There are numerous different causes of white spot lesions that influence how the enamel substructure is affected and which treatment option is selected. Once, the only treatment option for white spot lesions was drilling the defects away, but with a better understanding of the science and the aetiology, we have now been able to create minimally invasive, preventive alternatives. It is vital that the cause, size and depth of the white spot lesions are ascertained before providing treatment options to a patient, as treatment results will vary depending on the enamel substructure available. This paper will explore the main causes of white spot lesions and the recommended treatments for them.

Abstract
BACKGROUND/AIM Visual acuity and stereopsis both play an important role in developing posture and balance in children. The aim of this study was to investigate whether children with traumatic dental injuries (TDI) have abnormal stereopsis, due to a reduction in visual acuity, compared to children with good dental health. MATERIAL AND METHODS A total of 140 participants (75 with traumatic dental injuries resulting from falls and crashes, and 65 age-matched controls without dental trauma) were enrolled in this prospective, cross-sectional study. The participants underwent complete dental and ophthalmologic examinations. After the ophthalmologic examination, the stereo acuities were assessed by a Titmus stereo test at 40 cm. RESULTS Titmus test scores were significantly worse in the TDI group (mean score 252.46 ± 629.12 seconds of arc) compared to the control group (mean score 56 ± 27.39 seconds of arc) (P < .05). The percentage of subjects with abnormal Titmus test scores was higher in the TDI group (28%) than in the control group (3.1%). The mean anisometropia value was 3.03 ± 2.37 D and 0.55 ± 0.41 D in the TDI group and the control group, respectively (P < .001). The severity of anisometropia correlated with the degree of stereopsis (r = .83, P < .01). CONCLUSIONS The presence of abnormal stereopsis may lead to postural instability which can lead to traumatic dental injuries. The prevalence of abnormal stereopsis in children with TDI was higher than in children with good binocular vision and stereopsis.

Abstract
Data concerning the prevalence of developmental enamel defects and their association with dental caries in individuals with intellectual disability are scarce. This paper aims to evaluate the prevalence and distribution of developmental enamel defects and dental caries in the permanent dentition of special-care school children from Poznan (Poland). Out of 1091 students attending all special-care schools in the city, the study covered 268 subjects with intellectual disability (mild, moderate, severe, and profound) with permanent dentition, aged 10-20. One calibrated dentist performed dental examinations. The Statistica Software v10 was used for statistical analysis, assuming the level of statistical significance p ≤ 0.05. Among the subjects of the study, 19.40% presented developmental enamel defects. The number of teeth with changes ranged from 1 to 28, with maxillary incisors most frequently affected. Students without developmental enamel defects had more teeth observed with active caries compared to those with such changes (10.92% vs. 7.82%, p < 0.01). The highest number of students with developmental defects of enamel was observed in the group of individuals with mild intellectual disabilities. The present study revealed that in special-care students from Poznan, enamel defects and dental caries were frequently observed. However, individuals with developmental enamel defects did not show higher dental caries indices.

Abstract
Traumatic injuries to the primary dentition are critical events in dentistry not only due to the need for urgent care, but also since they have potential sequelae in the permanent dentition, with a prevalence ranging from 12% to 74%. The aim of this article was to provide an overview of the prevalence, etiology, and clinical and radiographic characteristics as well as the management of permanent teeth sequelae resulting from traumatic injuries to their deciduous predecessors. An extensive literature review was performed to reveal the current evidence on enamel discoloration with or without hypomineralization/hypoplasia, crown dilaceration, odontoma-like malformation, root anomalies, partial or complete arrest of root formation, sequestration of the permanent tooth germ, and eruption disturbances.

Abstract
This case report describes the interdisciplinary treatment of an ectopic horizontally placed maxillary right central incisor with severe root dilaceration. The root was distally angulated and entrapped by the root of the maxillary right lateral incisor. The initial force system was aimed at an occlusal displacement and applied to the crown. During the second phase, a button was cemented onto the apex of the impacted tooth. A force from the apex to a temporary anchorage device in the palate moved the root toward the midline. Finally, a root canal and an apectomy were performed and the central incisor could be moved to its ideal position. The treatment generated a normal height of the alveolar bone and an ideal occlusion with a healthy periodontium.

Abstract
Objective: This controlled study investigated the occurrence of sequelae to permanent successors (SPS) following traumatic dental injury in primary teeth (TDIp). Additionally, this study evaluated whether TDIp is a risk factor for SPS, with a focus on an association between SPS and the child's age and type of trauma. Materials and methods: The trauma group (TG) consisted of permanent teeth, whose antecessors had suffered TDIp, in a population of children with complete eruption of permanent teeth. The control group (CG) consisted of permanent teeth from the same individuals, whose antecessors had not suffered TDIp. There were 214 cases of TDIp with their respective permanent teeth. In the CG 247 permanent teeth, whose antecessor had not suffered TDIp, were included. Data concerning such teeth and when TDIp occurred (in terms of the child's age) and types of SPS were collected. The chi-square test, regression logistic with generalized estimating equations (GEE) test, and risk analyses were applied to investigate the associations. Results: Overall, 29% of the permanent teeth in the TG presented SPS. This was compared to the development disturbances in the CG, which was 7%. The TG demonstrated the highest risk for SPS (OR, 5.388; p = .0001). The discolouration of enamel (37%) was the most common type of SPS found. SPS was more prone to occur in permanent teeth whose antecessors had been intruded (39%; p < .001). TDIp when the child was 1-year old was associated with SPS (p < .001). Moreover, children who had TDIp had a 4.1 times higher risk of presenting SPS. Conclusions: TDIp is a risk factor for the development of SPS. All types of TDIp caused SPS in this research. Additionally, the younger ages at the time of the injury and intrusions were related to SPS.

Abstract
Traumatic dental injuries (TDIs) such as subluxations of primary teeth can have significant consequences on their developing successors. The purpose of this report is to present a 3-year-old boy who encountered subluxation injuries to his primary incisors which subsequently had an unusual consequence on the permanent successor. On the day of the TDI, based on clinical and radiographic examinations, a diagnosis of subluxation of teeth 52, 51 and 61 was made. By age 5, the patient reported that tooth 51 had exfoliated, and consequently, tooth 11 had erupted into the oral cavity, but it was very loose. Eventually, the patient lost the crown of tooth 11 during his routine daily activities. Furthermore, radiographic examination at age 11 revealed a small root-like structure in the tooth 11 region. It is very unusual to have premature loss of a permanent incisor following subluxation to its predecessor. Therefore, the present case serves as a good example to emphasize that even minor TDIs are of considerable importance as they may lead to unexpected consequences.

Abstract
BACKGROUND Dental trauma is a relatively common occurrence in childhood, with an impact exceeding that of periodontal diseases. It places a significant burden on the public health system because of its high frequency, impact on quality of life and consumption of resources. OBJECTIVES To identify changing trends of dental injury in patients between 0-18 years of age in Canada and provide a detailed assessment of dental injury patterns in patients attending a large pediatric tertiary care hospital. METHODS This retrospective study was carried out in two parts. Firstly, data from patients who presented to the emergency departments of the 15 Canadian hospitals involved in the Injury Reporting and Prevention Program (CHIRPP) from 1st January 1990 to 31st December 2013 was collected. Secondly, at the Hospital for Sick Children, charts of patients identified from the aforementioned database from the years 2008, 2012 and 2015 were accessed for additional clinical data. RESULTS Based on CHIRPP data there appears to be an increasing incidence in dental injuries presenting to emergency departments nationally. Participation in sports and cycling contributed to the majority of dental injuries. The use of safety equipment such as helmets with a face-grill and mouth-guard was low. CONCLUSIONS Our study demonstrates a rising incidence of dental injuries in young patients. Most dental injuries occurred during sports and playground related activities. The low rate of use of safety equipment and playground safety measures suggests that Canadian Standards Association standards for playgrounds could be more effective if strengthened by mandatory legislation.

Abstract
AIM To explore the profile of articles on traumatic dental injuries (TDI) in the primary dentition published in Dental Traumatology in the last 15 years using bibliometric analysis. METHODS Three researchers read all titles and abstracts of articles published in Dental Traumatology between 2000 and 2014 (excluding editorials and letters) and selected all articles on TDI in the primary dentition. The articles were categorized according to year of publication, country in which the study was conducted, study design, and topics addressed. Divergences were resolved by consensus between the researchers. RESULTS Among a total of 1257 articles published, 98 were initially excluded. Among the remaining 1159 articles, 152 (13.1%) focused on TDI in the primary dentition. The articles were conducted in 29 countries, with Brazil (38.8%) and Turkey (11.8%) accounting for the largest numbers. Cross-sectional studies (36.2%) and case report/case series (33.6%) were the most frequent study designs. Only two systematic reviews were published. The most commonly addressed topics were frequency/etiology/associated factors (36.8%), treatment (30.9%), and prognosis (19.7%). Among the articles addressing treatment, two-thirds were case reports or case series. The effects of TDI in primary teeth on their permanent successors were addressed in 20.4% of the articles (31/152). CONCLUSIONS The number of articles on TDI in the primary dentition has increased, but remains low. The evaluation of study designs and topics addressed identified gaps that could contribute to the development of new studies on TDI in the primary dentition, especially cohort studies that evaluate risk factors, prognosis, and treatment.

Abstract
BACKGROUND Trauma to primary teeth may have consequences. AIM To study frequency of enamel defects in permanent successors after luxation injuries, and to report carers' experiences. METHODS Children 8-15 years (n = 170) suffering luxation injury to primary dentition in 2003 were reexamined in 2010. Permanent successors (n = 300) were clinically examined and photographed. Data from dental records, registration form and a questionnaire were analysed by cross-tabulation and tested by chi-square and t-test. RESULTS Enamel defects were registered in 130 successor teeth, 22% due to trauma, 21% due to other aetiological factors (MIH, dental fluorosis, idiopathic). Successors with enamel defects were after concussion 8%, subluxation 18%, lateral luxation 41%, intrusion 38% and avulsion 47%. Enamel defects were associated with the child's age and severity of the injury (P < 0.05). Six children had enamel defects in successors of non-injured primary teeth. Anxiety recorded by carers was associated with severity and number of injured teeth (P < 0.05). According to carers eight children developed dental fear, seven were younger than 3.5 years and had had their injured teeth removed. CONCLUSION Minor luxation injuries and indirect trauma may cause enamel defects in permanent successors. Lower age at injury, severity and number of injured teeth affect carer and child negatively.

Abstract
OBJECTIVES The objectives of this study are to determine the effect of fluoride exposure on permanent tooth eruption patterns as well as to understand its effect on caries attack rate by accounting for the number of erupted tooth surfaces. METHODS We analyzed data from the 1986-1987 National Survey of Oral Health of US Schoolchildren to determine the mean number of erupted permanent teeth and permanent first molars according to fluoride level in drinking water. The analysis included 13,348 children aged 5-17 years with a history of single residence. We also estimated the attack rate (decayed, missing, and filled surfaces/surfaces at risk) for fluoride deficient, suboptimal, and optimally fluoridated areas adjusting for covariates. Multivariable statistical analyses were performed to control for potential confounders. RESULTS By age 7, almost all permanent first molars had erupted. The adjusted mean number of erupted permanent first molars per child were 3.81, 3.67, and 3.92 in areas with <0.3, 0.3-<0.7, and 0.7-1.2 ppm of fluoride, respectively. The adjusted caries attack rate in the first permanent molars among 5- to 17-year-old children was 93, 81, and 78 per 1,000 surfaces in fluoride deficient, suboptimal, and optimally fluoridated areas, respectively (P < 0.0001). This pattern of higher first molar attack rate among children in the fluoride-deficient communities was also observed in all erupted teeth. CONCLUSION Exposure to fluoride in drinking water did not delay the eruption of permanent teeth. The observed difference in dental caries experience among children exposed to different fluoride levels could not be explained by the timing of eruption of permanent teeth.

Abstract
STATEMENT OF PROBLEM New light-polymerized resin composites optimized for rapid infiltration of enamel lesions with resin light curing monomers are commercially available today to prevent enamel lesions from further demineralization and provide a highly conservative therapy. In addition, this technique has proved to be effective treatment for blending white spot lesions because the microporosities of infiltrated lesions are filled with resin. PURPOSE This clinical report presents and describes cases in which the minimally invasive infiltrant resin technique was used for blending different microporous lesions, mild-to-moderate fluorosis, and hypoplasia stains related to traumatic dental injuries. RESULTS The fluorosis stain showed visually perceptual improvements. In the cases of hypoplasia, stains were not completely blended. However, the general clinical outcomes of these cases were considered successful and recovered the patients' self-esteem. CONCLUSION Based on the results obtained, it could be concluded that the resin infiltration technique shows promising results and could be considered a minimally invasive procedure for mild-to-moderate fluorosis and hypoplasia stains. CLINICAL SIGNIFICANCE This case study allows a better understanding of the concept of the resin infiltration technique applied in other types of porous lesions, increasing its use as a therapeutic alternative for esthetic purposes in the philosophy of minimally invasive dentistry.
