An assessment of Brazilian dentists' knowledge about tooth fragment reattachment: A cross-sectional study.

BACKGROUND/AIM: Crown fractures are common traumatic dental injuries and tooth fragment reattachment is a viable option for restoring a fractured tooth. The aim of this study was to assess the knowledge and experience of dentists in the Federal District regarding the tooth fragment reattachment technique for enamel and dentin fractures. MATERIALS AND METHODS: For the cross-sectional observational study, an electronic form was designed with objective and self-report questions for dentists. The data were analyzed using descriptive statistics, with their absolute and relative frequencies. For the analysis of categorical variables, the nonparametric chi-squared or Fisher exact association tests were used in the statistical software R (version 4.2.1). RESULTS: A total of 416 dentists participated in the study (58.9% female and 41.1% male). Of these, 70% declared they knew about fragment reattachment, but only 42.3% reported previous experience with this procedure. The most common storage medium used for the fractured fragment was milk (78.1%), and the bonding material used for reattachment was light-cured composite resin (86.3%). A majority (66.3%) reported that for a patient with enamel and dentin fracture, with the crown fragment in good condition, they would choose to do the reattachment. CONCLUSION: Dentists demonstrated that they had adequate knowledge about the tooth fragment technique, although many did not have previous experience with this procedure.

Qualitative research in dental traumatology-A narrative review.

This review highlights the recent contributions of qualitative research in advancing understanding of dental trauma injury and the barriers and enablers to guide policy for improved patient-centred care including transitional care. It summarises the common approaches and methods used and outlines the key factors that guide the appraisal of qualitative studies. It highlights the importance of the application of qualitative research methods in dental research to generate rich and detailed data to provide explanations and insights into people's experiences, beliefs and attitudes and the complexity of human decision-making and behaviour. In the past decade while there have been a growing number of publications of qualitative studies in dental journals, qualitative studies remain a small percentage of the published dental traumatology research. This may be because of limited understanding about the background, methods and rigour of qualitative research.

Methods and applications of finite element analysis in dental trauma research: A scoping review.

Finite Element Analysis (FEA) is vital for understanding dental traumatology (DT) biomechanics, aiding diagnosis, treatment planning, and outcome prediction. This review explores FEA applications in DT research, evaluates their quality and outcomes, and assesses methodological aspects. Accordingly, recommendations for future researchers are provided. The study adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for scoping reviews and registered in Open Science framework. A comprehensive search using relevant text-words and MeSH terms was performed in established databases. The inclusion criteria encompassed all Finite element analysis (FEA)-based Dental traumatology (DT) studies without language or publication year restrictions. Risk of bias was assessed with the Risk of bias tool for the use of finite element analysis in dentistry (ROBFEAD) tool. Forty-six studies published from 2001 to 2023 were included in the qualitative synthesis. The studies were categorized into five domains and six subdomains based on objectives. Maxillary central incisors and surrounding structures were commonly modelled (n = 27). Most studies utilized Computed tomography (CT), Cone Beam CT, or micro CT. Traumatic injury forces ranged from 100 N to 2000 N, and occlusal forces ranged from 150 N to 350 N. All studies were rated as high risk of bias. Fory-six studies were categorized, with most focusing on stress distribution and fracture patterns in dento-alveolar structures under various conditions, while few assessed displacements. Methodological quality lacked robustness in model development and substructure properties. Future studies should address these limitations and enhance reporting practices.

Comparative assessment of scientific reach and utilization of the International Association of Dental Traumatology 2020 guidelines: An altmetric and citation analysis.

BACKGROUND/AIM: The updated version of the International Association of Dental Traumatology (IADT) guidelines was published online in May 2020 in the form of four papers. They are extensively used in dental trauma education in textbooks, undergraduate and postgraduate programs, and clinical workshops. Hence, this study aimed to assess the impact, global scientific reach, and utilization of these guidelines through altmetric and citation analysis. MATERIAL AND METHODS: The protocol was prepared after an expert group discussion. Dimensions database was used to derive the altmetric and citation data on April 10th, 2023. The data was extracted by using a self-designed pre-piloted form by two authors independently. The citing articles were further categorized into the type of study and the domains and subdomains of dental traumatology. The VOSviewer program was utilized to explore the correlation between the subdomains and the overlap of citations was assessed by creating a citation matrix. RESULTS: A total of 552 citations had been collectively received by the four papers. The highest was seen for the guidelines for fracture and luxation in permanent teeth (FL), avulsion in permanent teeth (AV), general introduction (GI), and primary teeth (PT). Dental Traumatology had the maximum number of citing papers for each guideline. They were from 52 countries with English being the commonest language. Overall, the maximum number of citations had been received in narrative reviews (n = 104) and the majority of cited papers were categorized in the therapeutic domains. The most common subdomain for the papers that cited GI, FL, and AV was "treatment protocols in permanent teeth", while it was "awareness of prevention and emergency management of traumatic dental injuries" for the papers that had cited PT. CONCLUSIONS: This analysis highlighted that the IADT 2020 guidelines are globally popular resources, which are widely used by the researchers across specialities and are intended towards clinical application.

Computer-aided design and computer-aided manufacturing poly (methyl methacrylate) interim veneers for immediate esthetic restoration of autotransplanted teeth.

Autotransplanted teeth in the maxillary anterior region should be restored or reshaped as soon as possible for functional and esthetic reasons as well as the well-being of the patient. However, such tooth restorations are frequently not carried out immediately after tooth transplantation because the process could have a negative impact on the healing process. The development of a simple, immediate, and atraumatic esthetic interim restoration would be of great benefit to both the clinician and patient and address all the concerns caused by immediately preparing the tooth postoperatively and cementing a permanent restoration. This report describes the use of CAD-CAM technology to create poly (methyl methacrylate) veneers preoperatively that can be cemented extraorally on the extracted donor tooth for the immediate and interim recontouring of autotransplanted anterior teeth.

A 3-year Retrospective Analysis of Dento-Alveolar Injuries at the University Children's Hospital Zurich (2018-2020).

Children and adolescents are vulnerable to dental trauma due to their active lifestyles, lack of coordination, and inexperience in recognizing potentially dangerous situations. Early recognition and proper management of dental trauma is crucial in order to minimize the risk of complications and ensure optimal outcomes. The aim of this study was to perform a retrospective analysis of all dento-alveolar injuries in children and adolescents who were treated at the University Children's Hospital Zurich from 2018-2020 by the resident physicians of the Centre of Dental Medicine of the University of Zurich. All information concerning age and sex distribution, seasonal and weekly variations, as well as aetiology, types of trauma and co-affected structures in the head and neck area from 389 patients was analysed. For data extraction, a parameterised Excel list was created, enabling a continuous data collection. In the study, 65% of the patients were male and 35% female. The average patient age was 7 years and 4 months. The highest frequency of trauma occurred in mixed dentition (49%), followed by deciduous dentition (36%) and permanent dentition (15%). Most of the accidents occurred in the second quarter of the year, especially in the month of May slightly more injuries were reported. The most common injuries were increased tooth mobility (40%) and tooth fractures without pulp exposure (34%). Less frequent were tooth fractures with pulp exposure (12%), lateral dislocations (29%), avulsions (21%), intrusions (8%), extrusions (6%) and root fractures (4%). As in many studies the upper central incisors were most often affected. Main causes of dental trauma were falls, especially by bike (18%) or scooter (14%). Soft tissue injuries or fractures, in the area of the head and neck occurred in 59% and 10% of the cases simultaneously accompanied by dento-alveolar trauma.

Evaluation of problem-based learning in dental trauma education: An observational cohort study.

BACKGROUND/AIM: Problem-based learning (PBL) allows higher thinking among dental students and has improved first-time pass-rates in predoctoral pediatric dentistry education. The aim of this retrospective observational cohort study was to evaluate the impact of PBL-based, traumatic dental injuries case discussions on predoctoral dental trauma education. MATERIALS AND METHODS: Student performance and perceptions after receiving dental trauma curriculum with or without PBL-based dental trauma case discussions were evaluated. All the students challenged their simulated patient-based assessments. Three recall-based, objective structured clinical examinations, and critical thinking competencies assessed student knowledge about management of traumatic injuries affecting primary or permanent dentition including avulsion. The scores and number of attempts for each competency were compared between the study cohorts using t-tests. Student's self-perceived learning outcomes were measured through a voluntary, five-question survey. Mantel-Haenszel ordinal Chi-square tests were used to assess for differences in rates of agreement on survey responses from the students. Linear regression was used to assess effect of training on scores adjusting for student type (predoctoral or advanced standing). Pearson's correlations were used to assess association between scores. Significance was set at 0.05. RESULTS: For the PBL cohort, there was a significant (p > 0.05) improvement in the first-time pass-rates and scores in three out of four competencies. A higher proportion of students in the PBL cohort perceived that their dental trauma education improved their radiographic and diagnostic skills compared to the cohort that did not receive PBL (p > 0.05). There was no correlation between recall-memory versus critical thinking competencies (r < 0.5). CONCLUSION: The PBL-based dental trauma case discussion had a positive impact on predoctoral student learning and perceived benefits while managing simulated traumatic dental injuries. Due to a lack of correlation between recall-memory and critical thinking assessments, evaluation of predoctoral student's dental trauma competencies should involve multi-model assessment.

Heat Shock Proteins in Tooth Development and Injury Repair.

Heat shock proteins (HSPs) are a class of molecular chaperones with expression increased in response to heat or other stresses. HSPs regulate cell homeostasis by modulating the folding and maturation of intracellular proteins. Tooth development is a complex process that involves many cell activities. During tooth preparation or trauma, teeth can be damaged. The damaged teeth start their repair process by remineralizing and regenerating tissue. During tooth development and injury repair, different HSPs have different expression patterns and play a special role in odontoblast differentiation and ameloblast secretion by mediating signaling pathways or participating in protein transport. This review explores the expression patterns and potential mechanisms of HSPs, particularly HSP25, HSP60 and HSP70, in tooth development and injury repair.

Head injuries caused by contact with teeth during sports and exercise activities in Japanese schools during the period 2012-2018.

BACKGROUND/AIM: During sports activities, teeth-related contact can cause injury to both ally and opponent players, which can lead to potential infections and aesthetic problems. However, the extent of such injuries remains unclear. This study aimed to clarify the frequency and situation of head injuries caused by teeth (HICBT) occurring under the supervision of schools in Japan. MATERIAL AND METHODS: HICBT records were extracted from the Japan Sport Council data on head injuries occurring reported during the 7-year period from 2012 to 2018 under the supervision of schools in Japan. RESULTS: Of the total 463,527 head injury cases during the study period, 4495 cases (approximately 1%) were HICBT. Of the HICBT cases, 3650 (81.20%) were related to sports and athletic activity. Such injuries were reported to occur most often during basketball with a rate of 57.07% and 50.43%; soccer/futsal was the next most common sport with a rate of 13.38% and 24.01% in junior high school and high school students. Tag games were responsible for a similar number of HICBT cases at 22.73% and 39.03% in kindergartens and elementary school students. CONCLUSIONS: A total of 4495 cases of HICBT were identified, accounting for about 1% of all head injuries under the supervision of schools in Japan during the study period. This result reminds us that our teeth could be the weapon against the players during sports events. HICBTs occurring during basketball and soccer/futsal, in which mouthguards are not mandatory, were conspicuous among junior and senior high school students. Active use of mouthguards in various sports will protect players as well as their teammates and opponents. Sports dentists should encourage the revision of rules, such as mandating the use of mouthguards, in popular sports with a high incidence of HICBT, such as basketball and soccer/futsal.

The ability of mouthguards to protect veneered teeth: A 3D finite element analysis.

BACKGROUND/AIMS: Professional and amateur athletes might have veneer restorations. The aim of this study was to investigate the protective effect of mouthguards on veneered anterior restorations. METHODS: A nonlinear dynamic analysis was performed to simulate conditions during an impact with or without a custom-made mouthguard. Using a computer-aided design (CAD) software, a slice of a human maxilla was designed containing an upper right central incisor. The model was composed of mucosa, cortical bone, trabecular bone, periodontal ligament, dentin, enamel, and pulp tissue. The enamel was prepared (feather design), restored with an indirect veneer (1.0 mm thickness), and duplicated to simulate both conditions with or without a mouthguard (4 mm thickness). Both models were subdivided into finite elements using the computer-aided engineering (CAE) software. Frictionless contacts were used, and an impact was simulated in which a rigid sphere hit the model at 1 m s-1 . Fixation was defined at the base of the bone. The elastic modulus of the veneer was assessed by using five different restorative materials (resin composite, hybrid ceramic, zirconia-reinforced lithium silicate, lithium disilicate, and zirconia). Von Mises stress, minimal principal stress, and maximum principal stress (in MPa) were obtained and plotted for visual comparison. RESULTS: Von-Mises results showed higher stress concentrations in the veneer's cervical labial region for models without a mouthguard. Observing the quantitative results for each model, the highest compressive (709 MPa) and tensile (58 MPa) stresses occurred in the situation without a mouthguard with a zirconia veneer, while the lowest occurred in resin composite veneer with a mouthguard (8 and 5 MPa). The mouthguard was able to reduce the stresses in the tooth structure and it also reduced the risk of fracture in all conditions. CONCLUSIONS: Mouthguards were beneficial in reducing the effects of dental trauma regardless of the restorative material used to manufacture the indirect veneer, since they act by dampening the generated stresses during the trauma event. Equal impact stresses on a mouthguard will lead to higher stresses in veneered teeth with more rigid restorative materials leading to a less protective effect.

Head and dental injuries among farriers and hoof care practitioners: A nationwide survey in Switzerland.

BACKGROUND/AIM: There is a paucity of evidence on injuries sustained by farriers and hoof care practitioners, two professions exposed to unique occupational hazards. The aim of this study was to collect and examine data on occupational head/face and dental injuries among farriers and hoof care practitioners in a nationwide survey in Switzerland. MATERIALS AND METHODS: Data on occupational head/face and dental injuries were gathered in a questionnaire-based, voluntary survey, which was mailed to all farriers and hoof care practitioners in Switzerland. The statistical analysis comprised multiple regressions with a nested design (α = 0.05). RESULTS: The survey included 278 respondents (response rate of 78.1%). Head/face injuries were more frequently reported by farriers than hoof care practitioners (60.6% and 20.7%, respectively). Among full-time workers, farriers had a higher chance of an occupational head/face injury compared with hoof care practitioners (p = .007). The rate of dental injuries, mainly related to a horse kick, was 11.1% and 1.9% among farriers and hoof care practitioners, respectively. Negligence in wearing mandatory eye protection was reported by 37.5% of respondents. CONCLUSIONS: Farriery and hoof care management entail a significant risk of occupational head/face and dental injuries. Preventive safety measures-eye protection in particular-and knowledge in dental first aid should be promoted among farriers and hoof care practitioners to decrease the frequency and severity of work-related injuries.

General and dental injuries sustained at concerts: A questionnaire-based study.

BACKGROUND/AIM: Evidence on the risk of injury at concerts is scant. The aim of this study was to collect data on general and dental injuries incurred by concertgoers in Switzerland and to investigate whether the frequency of accidents was related to music genre, gender and consumption of alcohol. MATERIALS AND METHODS: A questionnaire-based, cross-sectional study comprising 451 concertgoers in Switzerland was conducted on the timeframe January 2019 to February 2021. The survey gathered data on general and dental injuries, alcohol consumption and drug use. The statistical analysis included Fisher's exact tests, chi-squared tests, rank sum tests and logistic regressions (α = .05). RESULTS: There were 28.8% of respondents who reported an injury incurred at a concert. Contusion was the most prevalent injury, accounting for 33.8% of all injuries. Legs were the most commonly injured body part (34.6%). Injuries to their mouth/lips/teeth were reported by 17.7% of respondents. Dental injuries, accounting for 4.6% of all reported injuries, comprised four tooth fractures, one lateral luxation and one avulsion. The risk of injury while attending punk rock concerts was 8.6 times higher than for pop concerts (p < .001). In comparison with pop concerts, metal and rock concerts had an increased risk of injury by factors of 5.1 and 2.3, respectively (p ≤ .029). Neither gender nor drug use had a significant effect on the injury risk (p ≥ .3). Heavy alcohol consumption (>5 standard glasses) increased the risk of injury by a factor of 2.3 (p = .028). CONCLUSIONS: This study suggests that concert attendees at rock, metal and punk concerts face an increased risk of injury, which is likely due to the frequency of aggressive dance styles such as moshing. Heavy alcohol consumption leads to a greater risk of injury at concerts.

Sequelae in permanent dentition after trauma in primary dentition in patients assisted at hospital base Valdivia, Chile / Secuelas en dentición permanente por trauma en dentición temporal en pacientes atendidos en el hospital base Valdivia, Chile

Aim: To determine the type and frequency of sequelae in permanent teeth as a result of traumatic dental injuries in primary teeth in pediatric patients attended to at the Hospital Base Valdivia, between 2007 and 2012. Material and Methods: A descriptive study was conducted. The medical records of pediatric patients who were affected by traumatic dental injuries in primary teeth and went to the Sub-department of Dentistry of the Hospital Base Valdivia, Chile, were selected according to inclusion and exclusion criteria. The recorded data was: age of the child at the time of the accident, gender, affected primary tooth, type of traumatic dental injuries, and diagnosis of the permanent successor tooth. Descriptive statistics were performed. A chi-square test was used to establish differences between type of traumatic dental injuries and condition of the permanent tooth. Results: The most frequent diagnosis of traumatic dental injuries in primary dentition was subluxation. The primary tooth with the highest frequency of traumatic dental injuries was the right maxillary central incisor; 58.2% of the permanent successors presented some developmental disturbances. The most frequent sequelae observed in permanent teeth were chronological alterations of the eruption. Conclusion: There is a high frequency of sequelae in permanent dentition as a result of trauma in primary dentition. The most frequent sequel observed was chronological alteration of the eruption. It is fundamental to inform parents about the possible consequences that could arise and emphasize the importance of attending periodic follow up in order to prevent or minimize possible sequelae in permanent teeth.

Objectivo: Determinar el tipo y frecuencia de secuelas en dientes permanentes como consecuencia de lesiones dentales traumáticas en dientes temporales en pacientes pediátricos atendidos en el Hospital Base Valdivia, entre los años 2007 y 2012. Material y Métodos: Se realizó un estudio descriptivo. Se seleccionaron las historias clínicas, según criterios de inclusión y exclusión, de pacientes pediátricos que sufrieron lesiones dentales traumáticas en dientes temporales y que acudieron al sub-departamento de Odontología del Hospital Base Valdivia, Chile. Los datos registrados fueron: edad en el momento del accidente, sexo, diente temporal afectado, tipo de lesiones dentales traumáticas y diagnóstico del diente sucesor permanente. Se realizó estadística descriptiva. Se utilizó la prueba de chi-cuadrado para establecer diferencias entre el tipo de lesiones dentales traumáticas y el estado del diente permanente. Resultado: El diagnóstico más frecuente de lesiones dentales traumáticas en dentición temporal fue subluxación. El diente temporal con mayor frecuencia de lesiones dentales traumáticas fue el incisivo central superior derecho. El 58.2% de los dientes sucesores permanentes presentó alguna alteración del desarrollo. Las secuelas más frecuentes observadas fueron alteraciones cronológicas de la erupción. Conclusión: Existe una alta frecuencia de secuelas en la dentición permanente como consecuencia de traumatismos en la dentición temporal. La secuela más frecuente observada fue la alteración cronológica de la erupción. Es fundamental informar a los padres sobre las posibles consecuencias que podrían surgir y enfatizar la importancia de realizar un seguimiento periódico para prevenir o minimizar posibles secuelas en los dientes permanentes.

Prognosis of primary teeth following intrusive luxation according to the degree of intrusion: A retrospective cohort study.

BACKGROUND/AIM: The degree of intrusion is an important aspect to be evaluated when treating children following intrusive luxation. The aim of this retrospective cohort study was to evaluate re-eruption rates and the occurrence of sequelae in intruded primary teeth according to the degree of intrusion. MATERIAL AND METHODS: A total of 238 teeth from 168 patients diagnosed with and treated for intrusion over a 16-year period at a specialized trauma center in South Brazil were included in this study. Patient details, including demographic characteristics, tooth affected, presence of sequelae of trauma during the follow up (pulp necrosis and infection, crown discoloration and abnormal mobility), and any effects on the permanent successors, were collected from their records. Photographs were analyzed to determine the degree of intrusion (Grade I, II, or III) and spontaneous re-eruption during follow up. Re-eruption and occurrence of sequelae according to the degree of intrusion were evaluated using the chi-squared test. The level of significance was set at 5%. RESULTS: Most teeth were maxillary central incisors (87.8%) with Grade I intrusion (32.8%). In the first 30 days, 13.1% had signs of re-eruption. After 3-6 months, the frequency of re-eruption increased to 58.7%. Of the teeth evaluated 6 months or more after intrusion, 68% had re-erupted. Total intrusion (Grade III) was associated with pulp necrosis and infection (p = .002), but the degree of intrusion was not associated with the presence of crown discoloration or abnormal mobility. Of the 78 permanent successors evaluated, 52.6% had developmental disturbances. CONCLUSION: Most intruded primary teeth re-erupted spontaneously, and the degree of intrusion was associated with a worse prognosis.

The association of inadequate lip coverage and malocclusion with dental trauma in Brazilian children and adolescents - A systematic review and meta-analysis.

BACKGROUND/AIM: Dental trauma (DT) occurs frequently in children and adolescents. Therefore, understanding the factors associated with its occurrence in these age groups is important to establish specific preventive measures. The aim of this study was to investigate the relationships of lip coverage, overjet, and open bite to dental trauma in Brazilian children and adolescents. MATERIAL AND METHODS: The review protocol was registered in the PROSPERO database (CRD42020156290) and the bibliographic search was performed in nine electronic databases until July 2020. The studies included were observational, performed in Brazil, with healthy children and adolescents (0-19 years old), and without the restriction of date or language. Two reviewers assessed the individual risk of bias of the eligible studies with a standardized checklist. The meta-analyses were stratified by dentition stage and age range using fixed or random effects, odds ratio (OR) as the effect measure, and 95% confidence interval. The heterogeneity across studies was assessed with the I² test and the GRADE approach assessed the certainty of evidence. RESULTS: The search presented 2493 initial results, from which 55 met the eligibility criteria and were included. Most studies (67%) presented a low risk of bias and were published between 2000 and 2019. Children and adolescents with inadequate lip coverage are 1.86-2.36 times more likely to suffer from DT, while those with increased overjet are 1.94-3.11 times more likely. Children with primary dentitions and anterior open bites are 1.76 (95% CI: 1.20-2.59) times more likely to suffer from DT. The certainty of evidence varied from very low to moderate. CONCLUSIONS: Inadequate lip coverage, increased overjet, and anterior open bite are associated with the occurrence of dental trauma in Brazilian children and adolescents.

Dental trauma in primary dentition and the importance of its preservation until the eruption of permanent successor: a 6-year follow-up case report.

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.

Dental Trauma at a University Dental Clinic in Milan including the SARS-CoV-2 Period.

The aim of this study i.e., is to present the distribution of traumatic dental injuries (TDI) in 306 patients registered at the Unit of Dental Emergencies at a University Dental Clinic in Milan, Italy, between June 2019 and May 2021. This time frame includes the beginning of the SARS-CoV-2 pandemic. Information regarding age, gender, number and type of injured teeth, type of traumatic injury, and data on where or how the injury happened were recorded. Seventy-nine percent of patients can be classified as pediatric (under 14 years old), and in all age groups, male patients were found to be more susceptible (1.6:1). A total of 480 teeth were involved, 59% of which were deciduous, and 41% permanent. The most affected teeth in both dentitions were upper central incisors. In deciduous teeth, periodontal lesions were more common, whereas in permanent dentitions, dental fractures were diagnosed more often. Most data found in this study confirms the results found in the literature. The biggest difference, due to changes in daily routine during the SARS-CoV-2 pandemic, can be found by analyzing the incidence and etiology. As a matter of fact, there was a decrease in school accidents, whereas domestic falls remained constant.

Infraposition or infraocclusion- Is it time to rename?

Dental infraposition and dental infraocclusion, hereinafter referred to as infraposition and infraocclusion respectively, are terms that are often used interchangeably. This can be noted in the International Association of Dental Traumatology guidelines for the management of traumatic dental injuries, where infraocclusion is listed as an injury-specific outcome following avulsion of permanent teeth. Infraposition and infraocclusion are terms that have been used in the dental literature to describe teeth that interfere with the normal eruption and development of the permanent dentition. While teeth described in this manner share certain clinical characteristics that give rise to these terms being used interchangeably within the dental traumatology field, this may not necessarily be correct and may be confusing. The aim of this short communication is to start a discussion in the dental trauma community regarding the need for a more adequate term, particularly in relation to replanted teeth.

Aesthetic-functional reconstruction of dental fracture and its impact on the psychosocial aspect.

Traumatic dental injury (TDI) constitutes a public health concern. This injury occurs mainly in anterior teeth and brings disadvantageous psychosocial consequences that affect adolescents, as well as impairing their speech and eating habits. A healthy smile and facial aesthetic have an influence on social interaction, especially in the way individuals are seen, felt, and perceived by other people. Therefore, this paper aimed to report a dental trauma injury and its impact on the Oral Health-Related Quality of Life (OHRQoL). A 14-years old boy was referred to a Dental Trauma Care Program in a Brazilian Public University after falling from his own height. The patient had a crown fracture involving enamel and dentin without pulp exposure in the upper left central incisor. The oral rehabilitation was performed by using a composite resin associated with the silicone guide technique. Taking into account the integrality of the patient, the OHRQoL was assessed before and after the rehabilitation treatment with the application of the Brazilian version of the Child Perceptions Questionnaire (CPQ11-14)-Impact Short Form (ISF: 16). TDI in the anterior tooth had a negative impact on the social wellbeing of this adolescent. After the oral rehabilitation, the patient showed improvement on OHRQoL demonstrating autonomy and self-confidence in his reintegration into the social environment.

Conservative Treatment of Complicated Crown Fracture and Crown-Root Fracture of Young Permanent Incisor-A Case Report with 24-Month Follow-Up.

The complicated crown-root fracture of young permanent teeth is an uncommon traumatic dental injury that is usually treated in a complex way and is demanding not only for the dentist but even for the treated child. In this case report, we present the conservative treatment of a maxillary central incisor in a 10-year-old boy after a traumatic dental injury. Treatment included partial pulpotomy and adhesive fragment reattachment after reflection of the mucoperiosteal flap. The patient was fully asymptomatic at 24-month follow-up, with an aesthetically acceptable outcome. Vital pulp therapy and adhesive fragment reattachment can be a viable treatment option for complicated crown-root fractures, especially when treating immature permanent teeth.
