A retrospective study of dento-alveolar injuries of children in Ankara, Turkey

Evaluation of Nursing Students' Knowledge on Dental Injuries

BACKGROUND/AIMS

Emergency department visits for dental issues are mainly related to traumatic injuries. Knowledge of emergency department staff regarding diagnosis and treatment of dentofacial injuries is quite significant for prognosis of teeth and peripheral tissues. The aim of this study is to assess attitude, knowledge, education and self-confidence of undergraduate nursing students, who will work at emergency departments in the future, regarding diagnosis and treatment of dental traumatic injuries.

MATERIALS AND METHODS

This survey was prepared by modifying questions of the previous survey that had been internationally published. It was a face-to-face survey consisting of 15 questions regarding management of the dental traumas. Questions addressing participants' genders and year of study were added to the survey form. The survey was distributed to 1st, 2nd, 3rd and 4th-year undergraduate nursing students. Analysis results were presented in the form of frequencies. Pearson's chi-squared test and the Fisher-Freeman-Halton test were used for analysis of the categorical data. Multiple comparisons were made using the Bonferroni-correction Z test. The level of significance was set at p < 0.05.

RESULTS

The survey was responded by a total of 297 participants, including 47 men and 250 women. Participants consisted of 35.4% first-year, 28.6% second-year, 15.5% third-year, and 20.5% fourth-year nursing students. The third-year undergraduate students believed that they had adequate knowledge, and they were also the group that most strongly supported for administration of tetanus vaccine (p < 0.05). No significant difference was observed among nursing students regarding other topics. Students' knowledge and awareness levels respecting particularly avulsion injuries were found to be inadequate regardless of their year of study.

CONCLUSIONS

Knowledge of most undergraduate nursing students regarding diagnosis and treatment of dentofacial traumatic injuries were insufficient. An additional education is required for students during and after their formal education to manage dental traumas following graduation.

Risk of Healing Complications Following Alveolar Process Fractures in the Primary Dentition: A Retrospective Clinical Cohort Study

BACKGROUND/AIM

Alveolar bone process fractures in preschool children are not well documented in the literature. Alveolar process fractures are located very close to primary teeth and permanent tooth germs. This study investigates the risk of healing complications following alveolar process fractures in the primary dentition and potential sequelae in the permanent dentition.

MATERIALS AND METHODS

A retrospective cohort study was conducted involving 21 patients with 49 primary teeth involved in an alveolar fracture. The follow-up protocol included clinical and radiographic examinations at specified intervals up to the age of 6 years. Healing complications in the primary teeth such as pulp necrosis, pulp canal obliteration, ankylosis, infection-related resorption and premature tooth loss were examined. Sequelae in the permanent dentition was also registered when the permanent incisors had erupted.

RESULTS

Over a 3-year follow-up, the incidence of premature tooth loss was 51.2% [95% CI: 34.1%-68.4%], pulp canal obliteration was 42.5% [95% CI: 27.1%-57.8%], and pulp necrosis was 8.9% [95% CI: 0.6%-17.3%] following an alveolar process fracture. No cases of ankylosis were observed. Sequelae in the permanent dentition primarily included demarcated opacities and hypoplasia with a risk estimated at 24% [95% CI: 13%-39%] and 9% [95% CI: 2%-21%] respectively.

CONCLUSION

Alveolar process fractures in primary dentition are associated with several healing complications in the primary teeth. Although the likelihood of severe complications in the permanent dentition is low, young children are still susceptible to developing sequelae in their permanent teeth. These results highlight the importance of awareness of dental injuries following alveolar process bone fractures in the primary dentition.

Oral and maxillofacial literature from Middle East: a bibliometric analysis and list of top-100 most cited articles

OBJECTIVES

The aim of this work is to perform a bibliometric analysis on Middle Eastern oral and maxillofacial surgery through years and to compare the data with previous studies. A list of the top 100 most cited articles was generated.

METHODS

A Pubmed bibliographic search for literature journals specialized in oral and maxillofacial surgery in the Middle East was performed. A graphic representation of authorship and keywords was created with VOSviewer. Mendeley and Microsoft Excel were used for tabulation and data visualization. A list of the top 100 most cited articles was created using Web of Science. Some statistical tests were performed with a 95% confidence interval, which was considered significant.

RESULTS

A total of 6,536 articles were retrieved in fifteen selected oral and maxillofacial journals. A moderate correlation between number of publications and total population (R = 0.6052), low correlation with area (R = 0.302291), and a negligible correlation with the Human Development Index (HDI) were found (R = 0.1747). A disparity can be seen in the number of publications by country, leaded by Turkey (46.30%), Israel and Iran (13.68% each). The more common studied topic was oral surgery (25.77%), maxillofacial trauma (16.13%) and oral pathology (10.25%).

CONCLUSIONS

A useful list of the top 100 most cited articles on oral and maxillofacial surgery from Middle East has been created. Middle East publications on oral and maxillofacial surgery can be considered high quality (IF = 1.879). Some issues on performing an adequate selecting of MeSH keywords were discussed.

A retrospective study of emergent traumatic dental injuries in permanent teeth in Xi'an, China

Traumatic dental injury is one of the common injuries seen in the emergency department. To determine the distribution features of emergency traumatic dental injuries in Xi'an, China, data from the medical records of 623 patients (aged 6-78 years) were evaluated and analyzed according to age, gender, etiology, factors predisposing teeth to injury, and types of teeth traumatized. The patient records of 397 males (63.7%) and 226 females (36.3%), with a 1.8:1 male-to-female ratio, were included. The total number of traumatized teeth was 1475. The highest frequency of dental trauma was found in the 19- to 30-year age group (30.7%). The greatest frequency of dental trauma injuries was in May (13%). Over one-third of patients with traumatic injuries to permanent teeth (n = 218, 35%) injured 2 permanent teeth. The most commonly affected teeth were the maxillary central incisors (59.3%). The most common type of trauma was concussion (20.4%). There was statistically significant difference among the type composition ratio of age groups (P < .05). The most common causes of dental trauma were falls (50.2%). There was statistically significant difference among the etiological composition ratio of age groups (P < .05). Combined injuries were present in 120 teeth in 103 patients (16.5%). The epidemiological characteristics of dental trauma in Xi'an shows that the occurrence of dental trauma is closely related to the age, sex, time, type of injury, and cause of injury. There exists cross-correlation among the epidemiological factors. The most common type of trauma is concussion and the most common cause of dental trauma is fall. High incidence of combined injuries needs extra attention.

Regenerative endodontic therapy for external inflammatory lateral resorption following traumatic dental injuries: Evidence assessment of best practices

BACKGROUND

External inflammatory lateral resorption (EILR) following dental trauma is a severe complication that can lead to significant root loss and tooth extraction.

OBJECTIVE

The aim of this project was to review current evidence in the literature on regenerative endodontic therapy (RET) for EILR following traumatic injuries and assess the best treatment practices.

METHODS

Publications appearing in PubMed, from January 1, 2001 to January 9, 2022 were studied. Inclusion criteria were: (a) Publications in English; (b) Publications on RET and EILR; (c) Teeth subjected to dental trauma; and (d) Presence of intracanal bleeding and blood clots. Exclusion criteria were: (a) Conference proceedings; (b) Lectures; (c) Abstracts; and (d) Letters to editor; (e) Non-English publications.

RESULTS

355 publications were analysed. Nine met all inclusion criteria. In 10 (58.8%) teeth, triple antibiotic paste was used for an average of 26 days. Double antibiotic paste was used in 3 (17.6%) teeth for an average of 14 days. In 3 (17.6%) cases, calcium hydroxide (Ca(OH)₂ ) was used for 14 days and negative pressure irrigation was applied once on 1 (6%) tooth.

DISCUSSION

Using RET to treat EILR has some advantages compared to long term CA(OH)₂ dressing. RET requires shorter dressing time compared to CA(OH)₂ . This can significantly improve patient compliance. Additionally, in immature teeth, RET helps to arrest root resorption leading to continued root maturogenesis and revascularization. It is recommended that a meticulous follow-up should be conducted when RET is performed to assure early detection of treatment failure.

CONCLUSIONS

RET appears to be a good treatment modality producing biologic repair and improving prognosis in cases of EILR in post-traumatic tooth/pulp injuries. The key limitation of this study is that all publications included were either case reports or case series that usually tend to report successful outcome.

Evaluation of primary teeth affected by dental trauma in patients visiting a university clinic, Part 1: Epidemiology

OBJECTIVES

The retrospective study reported herein was the first of three that investigated dental trauma in primary teeth. This article discusses the study that aimed to reveal the epidemiology of trauma with data such as prevalence, risk factors, and types of injuries, and to highlight prevention.

MATERIALS AND METHODS

The records of 320 patients aged 0-9 years who visited the Erciyes University Faculty of Dentistry Pedodontics Department due to dental trauma were evaluated according to the age, gender, medical condition, season, oral habits, trauma environment/type/cause, personal characteristics, and number of siblings. The chi-square test was used to compare the categorical variables by group.

RESULTS

Of the patients, 25.9% were aged 24-35 months at the time of study, 62.8% were male, 38.1% had two siblings, 37.2% had a sucking habit, 93.4% had a healthy medical condition, 41.3% experienced the trauma in summer, and 26.3% were aged 30-34 months at the time they incurred the trauma. Of the traumas, 54.1% were caused by falling, 60% occurred at home, 23% pertained to lateral luxation, and 70% were incurred when the patients were with their mother.

CONCLUSION

Given the results of this study, mothers with low education levels should be informed about their children's risk of incurring injuries from falling at home, especially in summer. Parents should also be warned that their children's oral habits increase their risk of trauma.

CLINICAL RELEVANCE

This study can help increase the knowledge level of clinicians, can raise social awareness, and can guide plan formulation for preventing risks.

Management of a Complex Dentoalveolar Traumatic Injury with Multiple Avulsions

Background

Dentoalveolar trauma is a major cause of tooth loss in children. Avulsion, luxation, crown, and root fracture are the injuries to primary and permanent dentition. The incidence of trauma for maxillary anterior teeth ranges for 4%-91%. Many case reports have been published regarding the treatment of trauma to anterior teeth; however, case reports comprising multiple avulsions including canines and premolars are rare in literature.

Method

After mouth rinsing was done with 2% betadine solution, the luxated teeth numbers 31 and 42 were repositioned into the tooth socket and were secured with the composite resin-wire splint. Tooth number 32 was extracted because it was disarticulated from the socket, and the socket was disrupted because of the alveolar fracture. The maxillary avulsed teeth could not be reimplanted because of the alveolar socket damage which was due to the alveolar bone fracture.

Results

The patient was reevaluated for the removable prosthesis in recall visits; the patient was well adapted to the appliance with no complaints regarding mastication and speech. The patient was advised to report periodically for further adjustments in the prosthesis and for radiographic evaluation.

Conclusions

This case report includes proper history taking, diagnosis, and treatment of a complex dentoalveolar trauma along with short-term prosthetic rehabilitation for improvement of aesthetics, phonetics, and mastication of growing child.

Traumatic intrusion of primary tooth: a case Report

Introduction: Anterior teeth are of utmost importance with regard to chewing, speaking, and beauty. Therefore, any traumatic dental injury has psychologically undesirable effects on children and their parents. The present study reported a case of a traumatic dental injury induced by falling off a chair and referral to an emergency department as well as measures taken for dental reconstruction and patient's improvement. Case Report: Parents with a 3-year-old girl came to the Clinic for Pediatric and Preventive Dentistry at University Dental Clinic Center "St. Panteleimon", Skopje with injuries to her face and oral structures resulting from a fall from a chair. The extraoral examination revealed a laceration on the submental skin surface and an injury to the upper lip. The child was examined and it was found that the maxillary left primary central incisor was compressed in the alveoli. The surrounding soft tissue was injured. Intraorally, the anterior segment of the maxilla showed injury consistent with low-velocity blunt-force trauma, including several lacerations of the gingival tissues. The patient's maxillary left central incisor was intruded from the socket. Conclusion: The prognosis of many cases of dental injuries is time-dependent. The intrusion of a tooth can have ramifications and the possibility that it has been fully intruded should be considered. The use of a radiograph is of great importance for the correct diagnosis of deciduous tooth intrusion.

Changes in admission laboratory tests in patients with maxillofacial fractures and the influence of dento-alveolar trauma

BACKGROUND/AIM

There are few studies in the literature evaluating possible alterations in laboratory tests in patients with maxillofacial fractures. The aim of this study was to analyze the changes in admission laboratory tests of patients with maxillofacial fractures with indications for surgical treatment, including the influence of dento-alveolar trauma.

MATERIAL AND METHODS

Data from complete blood counts, blood coagulation tests, blood chemistries, and urinalysis results were obtained. The occurrence of concomitant dento-alveolar trauma was noted. The medical records were also re-evaluated later to verify the treatment outcome and the occurrence of complications. Statistical analyses were performed using the likelihood-ratio test to verify significant changes in the evaluated parameters (P ≤ .050).

RESULTS

There was a prevalence of males (78%) with a mean age of 35.9 years. Lower erythrocyte counts, hemoglobin levels, and/or hematocrit were observed in males with associated fractures and with simultaneous dento-alveolar fractures. Higher mean neutrophil, segmented neutrophil, and lymphocyte counts were observed in patients with simultaneous dento-alveolar trauma. A higher mean activated partial thromboplastin time (aPTT) ratio was also observed. Lower potassium levels were observed for patients in the fourth decade of life. Higher leukocyte counts not associated with trauma were observed in the urinalysis results of females and in the group of patients aged 20 or younger. Verification of treatment outcome showed two cases of infections and two cases that needed re-operation after mandible fractures. These four cases showed no significant changes in laboratory tests regarding the predisposition for complications.

CONCLUSION

Patients with maxillofacial fractures had neutrophilia, increased aPTT, and non-traumatic leukocyturia. There was an influence of associated fractures and dento-alveolar trauma on the decrease in red blood cell parameters, neutrophilia, and lymphocytosis and of age on hypokalemia.

Changes in the aetiological factors of dental trauma in children over time: An 18-year retrospective study

BACKGROUND/AIM

Dental trauma causes significant aesthetic, functional and psychosocial problems that often require emergency attention in children. The aim of this retrospective study was to assess the factors related to dental injuries in children. A secondary aim was to better understand how to improve the education given to children, parents and teachers in schools regarding dental trauma.

MATERIALS AND METHODS

Records of children who were referred to the Department of Pedodontics at Suleyman Demirel University were reviewed. A total of 1971 patients with a history of dental trauma who attended the clinic from 1999 to 2017 were evaluated. The following information was recorded: age, gender, year, aetiology, location, season and time elapsed after trauma. Results were evaluated using the Pearson chi-square test.

RESULTS

The patients' average age was 8.56 ± 0.08. Dental injuries were frequent in the 7- to 12-year age group (55.9%). Children in the 0- to 6-year age group attended the clinic more frequently during the years 2013 and 2017 compared to previous years. Boys had a higher frequency of trauma than girls (P < 0.05). The most frequent cause of trauma was falls (46%). The accidents occurred predominantly in the street (41.8%). Trauma that took place at home increased in the later years of the study period, whereas the percentage of injuries occurring in schools decreased. The ratio of patients who attended the clinic within the first two days after trauma was 33.4% between 1999 and 2007, and this increased to 59.8% between 2013 and 2017. The majority of the injuries occurred during the summer.

CONCLUSIONS

The aetiological factors related to trauma in children, and the number of patients who attended the clinic, have not changed over the 18-year period but the elapsed time to attend the clinic has changed. Education will increase the awareness regarding the importance of emergency intervention immediately following dental trauma.

Retrospective evaluation of patients admitted to Karadeniz Technical University Pediatric Dentistry clinic due to trauma

Purpose:

Traumatic dental injuries are among the commonly observed problems in the primary and permanent teeth. The rate of prevalence of dental trauma varies globally. In this study, we investigated the type of dental trauma, related factors, and treatment procedures in children.

Subjects and methods:

During a 5-year period (January 2011–January 2016), 416 children aged in the range of 1–15 years were admitted to our clinic with dental trauma. The cause and type of the dental trauma in the primary and permanent teeth and their relation with gender and age were evaluated using the chi-square test, and their distribution by age was evaluated using regression analysis.

Results:

Overall, girls and boys comprised 37% and 63% of the study population, respectively. The mean age was 8.5 years. Falls (61.1%) were the most common cause of traumatic dental injuries, and enamel–dentin fracture (26%) was the most common dental trauma type.

Conclusion:

Traumatic dental injuries in children are common. A large proportion of patients without any clinical symptoms (15.8%) did not seek any treatment after the trauma. Teachers, parents, and children should be informed about the action to be taken when dental trauma occurs and about the importance of immediately taking the child to a dentist after the trauma to ensure an accurate diagnosis, an optimal treatment plan, and positive outcome.

Dental injuries in patients associated with fracture of facial bones

PURPOSE

To assess different types of dental injuries associated with facial bone fractures.

METHOD

One hundred dentate patients were selected randomly of all age and gender who had maxillofacial trauma only and having dental injury in association with facial bones fractures were included. They were thoroughly examined for injury/fracture to facial region as well as for dental injuries (teeth). Tooth injuries were noted according to Ellis classification. The data was collected, compiled, and put to statistical analysis.

RESULTS

Dental injuries were more in females than males found to be statistically significant with (p < 0.05).Crown fracture of maxillary teeth was more as compared to mandibular except molars found to be statistically significant (p < 0.05). Root fracture was more in maxillary incisors followed by canine as compared to mandibular incisors and canines found to be insignificant. Avulsion, extrusion and luxation were more in maxilla as compared to mandible found to be significant.

CONCLUSION

Different types of tooth injuries associated with facial bone fracture found more in females and maxillary teeth.

Clinical Performance and Epidemiologic Aspects of Fractured Anterior Teeth Restored with a Composite Resin: A Two-Year Clinical Study

PURPOSE

To investigate the etiologic factors, effect of age and gender on dental trauma, and to evaluate the performance of composite resin on the fractured crown of permanent anterior teeth.

MATERIALS AND METHODS

Over a 2-year period, 73 permanent teeth from 51 patients with dental trauma were treated with direct composite resin restoration. Informed consent and standardized trauma forms were completed by the patient; teeth were restored with a submicron hybrid composite resin (Spectrum TPH) and respective adhesive system (Prime&Bond NT). Sixty-nine teeth were directly restored without fiber posts, while four were treated with fiber posts. Two experienced clinicians, besides the operator, evaluated each restoration at 6-, 12-, and 24-month follow-ups according to US Public Health Service (USPHS) criteria for the following characteristics: anatomical form, marginal adaptation, color match, marginal discoloration, surface roughness, and caries. Data were analyzed using the Wilcoxon Signed Rank, Kruskal-Wallis, Mann-Whitney U, and Siegel and Castellan tests.

RESULTS

A total of 73 traumatized teeth in 51 patients aged from 14 to 64 years (mean age 25.47 ± 14.058 years) were assessed according to the Ellis classification and restored over a 2-year period. Crown fractures were more common in the maxilla (84.9%) and caused by falls (58.8%). At the end of 24 months, a total of ten restorations were lost. The survival rate after 24 months was 82.14%. There were statistically significant differences in marginal adaptation between the 6-, 12-, and 24-month follow-ups. Although changes in marginal discoloration over time were not significant (p = 0.194), changes in color match were significant (p = 0.029).

CONCLUSION

Within the limitations of this study, direct composite restorations were accepted as clinically satisfactory.

Prevalence of anterior dental trauma and its associated factors among children aged 3-5 years in Jaipur City, India - A cross sectional study

OBJECTIVE

To study the prevalence of anterior dental trauma and its associated factors among 800 preschool children aged 3 to 5 years in Jaipur City, Rajasthan, India.

MATERIALS AND METHODS

A cross-sectional survey was conducted among children aged 3-5 years, who were enrolled in various private and public schools in Jaipur. Parents were asked to fill a form addressing socio-demographic data and clinical examinations were performed by a single dentist. Traumatic dental injuries (TDI) were assessed and recorded based on Andreasen's classification. Associated factors such as sex, socioeconomic status (SES), and the type of injury were also analyzed. The data were analyzed statistically using Statistical Package for the Social Sciences software (version 20).

RESULTS

An overall 10.2% prevalence of TDI was observed among the study population. TDI were reported to be more among male children (11.87%) compared to female children (8.14%). Enamel fractures (69%) were the most prevalent type of anterior dental trauma. Upper central incisors were the most frequently affected. The SES of the parents had little influence on the prevalence of TDI.

CONCLUSIONS

The prevalence rate of dental trauma among children aged 3-5 years was 10.2%. Associated factors, such as SES, were observed to be not significantly correlated to dental trauma among the studied preschoolers.

Association between Traumatic Dental Injury, Obesity, and Socioeconomic Status in 6- and 13-Year-Old Schoolchildren

Obesity and poverty are independent risk factors in trauma-related morbidity in children as well as adolescents. The main objective of this study was to investigate the association between traumatic dental injury, obesity, and socioeconomic status in 6- and 13-year-old schoolchildren in Davangere city, Karnataka, India. Data were obtained from 1,550 schoolchildren. Dental trauma was classified according to Andreasen's criteria. The medical evaluation assessed the Body Mass Index. Overjet was considered a risk factor when it presented values higher than 3 mm, whereas lip coverage was classified as adequate or inadequate. With appropriate sample weighting, relationships between traumatic dental injury and other variables were assessed using the chi-squared test and multivariable logistic regression. Overall prevalence of dental injuries was 10.52% (3.6% in 6-year-olds and 17.2% in 13-year-olds). Boys experienced more injuries than girls, 11.03% and 9.97%, respectively (p>.05). There was a statistically significant difference between traumatic dental injury and overjet (95% confidence interval [CI] [2.06, 4.78], p < 001) and between traumatic dental injury and inadequate lip coverage (95% CI [1.23, 4.65], p < .001). When adjusted for covariates, the logistic regression model showed that there was a significant association between obese children (p < .05) and dental trauma prevalence. Children from low socioeconomic status had an odds ratio 2.33 (95% CI [1.05, 3.97]) times higher likelihood of having dental trauma than children from medium and upper socioeconomic status. To conclude the results of this study support an association between traumatic dental injuries, obesity, and poverty.

Multidisciplinary management of an unusual case of multiple developmental defects in lateral incisor followed by intrusive injury to primary incisors

Dental traumatic injuries occur frequently in children. The close relationship between the apices of primary teeth and germ of the permanent successors can lead to developmental disturbances in the permanent dentition. Developmental disorder can occur in any tooth. One of the most common teeth affected is lateral incisor. These developmental anomalies can cause various clinical problems. Clinical and radiographic characteristics of these anomalies may sometime present confusing picture. Therefore, recognition of this condition, early diagnosis, and treatment are important to avoid complications. High prevalence of dental trauma in young children emphasizes the need of educational and preventive programs in schools. Dentist plays important role in early diagnosis of disturbances in the permanent successor teeth by rigorous clinical and radiographic follow-up examination.

Management of maxillary alveolar bone fracture and severely intruded maxillary central incisor: report of a case

An 11-year-old male who injured his maxilla and right maxillary central incisor and lip during a fall was presented to our hospital. His lower lip and upper gingiva were lacerated with swelling and epistaxis, and he had a maxillary alveolar bone fracture and severe intrusion of the right maxillary central incisor, which had penetrated the floor of the nasal cavity with avulsion. Under local anesthesia, we repositioned the incisor and bone segment and fixed them with a titanium micromesh plate and self-tapping screws and splints. The incisor was also treated by root canal 3 days after the operation and was restored with a crown. We performed root canal filling 1 month later. Five months later, the plate and screws were removed. In prognosis of our case, no symptoms of inflammatory root resorption or ankylosis have observed for more than 1 year and 6 months of follow up based on both clinical and radiographic findings.

Management of intrusive luxation with immediate surgical repositioning

Intrusive luxation is one of the most severe forms of traumatic injuries in which the affected tooth is forced to displace deeper into the alveolus. As a consequence of this type of injury, maximum damage occurs to the pulp and all the supporting structures. This report presents a case of severe intrusive luxation of mature maxillary central and lateral incisor in a 40-year-old male. The intruded tooth was immediately repositioned (surgical extrusion) and splinted within hours following injury. Antibiotic therapy was initiated at the time of repositioning and maintained for 5 days. Pulp removal and calcium hydroxide treatment of the root canal was carried out after repositioning. Splint was removed 2 months later. Definitive root canal treatment with Gutta percha was accomplished at a later appointment. Clinical and radiographic examination 6, 12 and 24 months after the surgical extrusion revealed satisfactory progressive apical and periodontal healing.

Management of intrusive luxation in the primary dentition by surgical repositioning: an alternative approach

Intrusive luxation is the most common trauma during early infancy which results in the displacement of the tooth into its alveolus. Depending on the severity of the intrusion, the American Academy of Pediatric Dentistry recommends either extraction or spontaneous re-eruption for the primary tooth. This case report provides a brief insight into surgical repositioning as an alternative treatment option for the management of intruded primary tooth in a 4-year-old girl.

Reattachment of an Autogenous Tooth Fragment in Complicated Crown Fracture

The occurrence of dental traumas in children is on the rise, according to the literature, and require correct and adequate treatment specific to each fracture in order to preserve the remaining tooth. This article reports a case of a complicated crown fracture of maxillary right central incisor. It describes the reattachment of the original tooth fragment to the fractured tooth, provides benefits of maintaining the tooth's shape, color texture and translucency of the restoration.

Traumatic anterior dental injuries in 7- to 12-year-old Brazilian children

The aim of this study was to determine the prevalence and risk factors of dental trauma in the permanent anterior teeth of schoolchildren in Campina Grande, Brazil. A sample of 448 schoolchildren, 228 boys and 220 girls, aged 7-12 years, were randomly selected from 17 public schools in an urban area. The sample selection was carried out in two stages: first, schools were selected by simple sampling and then children were chosen using a proportionality coefficient. Data were collected through clinical examinations and interviews, after examiner calibration. Overjet (OJ) was considered a risk factor when it presented values higher than 3 mm, while lip coverage was classified as adequate or inadequate. Yates' chi-squared test verified the association between the variables and odds ratio. Significance level was set at 5%. The prevalence of dental injuries was 21%. Boys experienced more injuries than girls, 21.9% and 20%, respectively (P > 0.05). Falls and collisions were the main causes of dental trauma, 63.8% and 24.5%, respectively. There was a statistically significant difference between traumatic dental injuries (TDI) and OJ (95% CI 0.22-0.63) (P < 0.001) and between TDI and inadequate lip coverage (95% CI 9.16-34.93) (P < 0.001). Data indicated that boys presenting an OJ size >3 mm and inadequate lip coverage were more likely to have TDI in Campina Grande, Brazil.

The restoration of a maxillary central incisor fracture with the original crown fragment using a glass fiber-reinforced post: a clinical report

This report describes an esthetic, conservative, and economical alternative restoration technique for a fractured central incisor using the patient's own tooth crown piece and a bondable reinforcement glass fiber. Although the long-term durability of this adhesive post core restoration remains unknown, it remains successful after 1 year.

A retrospective evaluation of crown-fractured permanent teeth treated in a pediatric dentistry clinic

A retrospective study was carried out on the dental trauma records of 93 patients (55 boys, 38 girls) with 129 crown-fractured teeth. The patients' average age was 9.57 years (SD 1.57), ranging between 7 and 15 years. Uncomplicated crown facture (comprising enamel-dentin) was the most observed type of injury (n = 107, 83%). Only 15 patients (16.13%) sought treatment in less than 24 h following the injury. Of 41 injured teeth (31.79%) the apices were open at the time of presentation at the clinic. The initial treatment of these injured teeth were interim restoration with acid-etch and composite (69%), Cvek amputation (2.33%), fragment reattachment (1.55%), apexification (APX, 10.07%), and root-canal treatment (RCT, 17.05%). Out of 94 teeth, which were diagnosed as vital on admittance, 23 (24.46%) later developed pulp necrosis and required APX or RCT depending on their apical status. In 66 teeth (51.16%) definitive treatment was provided with only esthetic restoration (ER), while in 15.50% and 26.68% of injured teeth ER was carried out following APX and RCT, and RCT, respectively. Definitive treatment was provided in 3-6 months for 29.45% of the injured teeth, while 27.13% and 20.16% of teeth received definitive treatment within 1-3 months and 6 months to 1 year, respectively. Type of crown-fracture, elapsed time following injury, and vitality of the tooth on admittance and pulp necrosis observed were significantly related to the total time spent for definitive treatment (P < 0.05).
