Traumatic dental injuries over an 8-year period at a German dental center: a retrospective overview and cross-sectional analysis.

BACKGROUND/AIM: The aim of this study was to analyze a population of patients who had suffered from traumatic dental injuries (TDIs) by using different patient-, trauma- and treatment-related parameters. MATERIAL AND METHODS: All dental records of patients ≥ 3 years old who had presented at the dental emergency service between Jan 1, 2009 and Dec 31, 2016 for the treatment of dental trauma were analyzed. A total of 2758 patients were invited for a recall examination at the Department for Dental Surgery and Implantology, ZZMK Carolinum, Goethe University Frankfurt, Germany; of these, 269 patients attended their recall appointments. RESULTS: The enrolled patient population consisted of 1718 males and 1040 females, with a mean age of 19.63 years (median 12.00 ± 17.354 years). A total of 4909 injured teeth were assessed, with a mean of 1.78 injured teeth per patient (median 2.00 ± 1.279). Males were found to be more frequently affected by TDIs compared to females (1.65:1). The majority of these injuries occurred in the first two decades of life (66.1%; n = 1824). The majority of the patients presented for initial treatment within 24 h of their accident (95.7%). The most frequent TDIs were isolated luxation injuries 49.4% (n = 2426) and isolated crown fractures 30% (n = 1472). Combination injuries were diagnosed in 20.6% of the cases (n = 1011). CONCLUSIONS: Based on the findings of the present analysis, it can be concluded that males were more frequently affected by TDIs than females. Most patients had suffered from TDI before they had turned 10 years of age. Overall, the enamel-dentin fracture was found to be the most frequent injury, followed by concussions and lateral luxations.

Dental and Dentoalveolar Injuries in the Pediatric Patient.

Dental and dentoalveolar injuries are common in the pediatric population. Management is predicated on the type of tooth injured (primary or permanent), extent of injury, the dental and behavioral age of the patient, and ability of the patient to tolerate treatment. Although many dental injuries occur in isolation, a systematic evaluation of the patient is mandatory to confirm the absence of basal bone fractures of the maxilla or mandible, traumatic brain injury, cervical spine injury, and/or facial soft tissue injury. Long-term follow-up is paramount to achieving a functional occlusion and optimal dental health following injury.

Epidemiology and severity of traumatic dental injuries in permanent teeth: A 20-year retrospective study.

This study aimed to assess the traumatic dental injuries (TDIs) in permanent dentition among patients who attended at the outpatient clinic of a Brazilian dental school, during the last 20 years, and to investigate factors associated with the severity of these injuries. Clinical records of patients who attended a specialized center for dental trauma care in Brazil presenting at least one TDI in a permanent tooth, between the years 2000 and 2019, were reviewed. The data recorded were sex, age, affected arch, etiology, number, and type of the teeth affected, and classification and severity of the TDIs. The diagnosis and classification of the TDIs were based on the guidelines of the International Association of Dental Traumatology (IADT). The severity of each patient's injuries was defined as mild, moderate, or severe. Descriptive statistics, chi-square and multinomial regression analyses were used to evaluate the results. The significance level was set at 5%. A total of 837 clinical records were included, totaling 2357 teeth. Males were more prevalent than females. The patients' age ranged from 5 to 71 years. The most common traumas were avulsion (n=512) and uncomplicated enamel-dentin fracture (n=488). Univariate analyses showed that there was a statistically significant association between age group (p=0.004), etiology (p=0.000) and number of teeth affected (p=0.000) with severity of dental trauma. In conclusion, TDIs that occurred in Piracicaba and region are epidemiologically similar to those found worldwide, and that more severe injuries are related to age range, etiology and number of teeth affected.

Emergency Facial Injuries in Athletics.

Dental and oral injuries are a common occurrence in sport. Initial evaluation should always begin with an assessment of the patient's airway, breathing, circulation, as well as identification of associated injuries. Tooth avulsions are the only true dental emergency. Oral lacerations frequently do not require repair; however, special attention should be paid to lip lacerations involving the vermillion border. Most tooth and oral lacerations can be treated on the field with urgent referral to a dentist.

Factors associated with the survival of primary maxillary anterior teeth after intrusive luxation: a retrospective longitudinal study.

PURPOSE: To evaluate the survival rate of primary maxillary anterior teeth following intrusive luxation and identify associated factors. METHODS: A retrospective longitudinal study was conducted at a primary dental trauma centre using 88 dental records of children with intrusive luxation between 2007 and 2018. The variables of interest were time the tooth remained in the alveolus, degree of intrusion, accentuated overjet, lip protection, visible plaque, compromised germ of the permanent successor, clinical signs of infectious and inflammatory processes, endodontic treatment, pulp canal obliteration, sex, age at the time of trauma, family income, mother's schooling, and immediate care. Descriptive, bivariate, and Cox regression analyses were performed (p < 0.05; 95% CI). RESULTS: The 88 dental records of children with intrusive luxation included 128 teeth. Survival rate throughout the follow-up period was 65.6% (n = 84). Age older than three years and eight months (HR 2.28; 95% CI 1.04-4.99; p = 0.039), the development of an infectious process (HR 3.51; 95% CI 1.39-8.86; p = 0.008), development of an inflammatory process (HR 2.35; 95% CI 1.17-4.71; p = 0.016) and compromised germ of the permanent successor (HR 4.38; 95% CI 1.99-9.61; p < 0.001) were associated with a lower survival rate of intruded primary maxillary anterior teeth. CONCLUSION: The survival rate during the follow-up period of intruded primary maxillary anterior teeth was considered high. A significantly lower survival rate was associated with age, the occurrence of an infectious process and inflammatory process, and the compromised germ of the permanent successor.

Resumen Introducción: Los traumatismos dentoalveolares (TDA) son eventos que ocurren frecuentemente, llegando a comprometer órganos dentarios, sus tejidos de soporte, los maxilares y los tejidos blandos de la cara. Las estadísticas revelan cifras significativas en cuanto a la incidencia y prevalencia de estos accidentes, por lo que son considerados como un problema de salud pública global. Objetivo: Determinar la prevalencia de trauma dentoalveolar (TDA) en la parroquia urbana Hermano Miguel del cantón Cuenca- Ecuador en el año 2019. Materiales y Métodos: La investigación forma parte del proyecto "Macro estudio epidemiológico del trauma dentoalveolar en niños, adolescentes y adultos, del Cantón Cuenca, 2019" de la Universidad Católica de Cuenca. El diseño de investigación fue descriptivo/analítico y retrospectivo. Se utilizó un cuestionario validado por expertos, obteniendo información de 320 personas en 78 viviendas de entre 2 y 11 habitantes (M=4; DE=2) en 11 cuadras escogidas de forma aleatoria. Resultados: La prevalencia de trauma en la muestra fue del 8.1% (n=26); en el 28.2% (n=22) de viviendas visitadas se registraron una (23.1%) o dos (5.1%) personas con golpes en los dientes. Conclusión: El traumatismo dentoalveolar, por la frecuencia con que se presenta, se considera una urgencia odontológica de suma importancia para mantener en boca la pieza dentaria afectada y los tejidos involucrados; se considera que la arcada superior recibe más traumatismos y las causas más frecuentes suelen ser las caídas.

Abstract Introduction: Dentoalveolar trauma (DTA) are events that occur frequently, compromising dental organs, their supporting tissues, the jaws and the soft tissues of the face. Statistics reveal significant figures regarding the incidence and prevalence of these accidents, which is why they are considered a global public health problem. Objective: To determine the prevalence of Dentoalveolar Trauma (TDA) in the urban parish of Hermano Miguel in the canton of Cuenca- Ecuador in 2019. Materials and Methods: The research is part of the "Macro epidemiological study of dentoalveolar trauma in children, adolescents and adults in Cuenca Canton, 2019" of the Catholic University of Cuenca. The research design is descriptive/analytical and retrospective. A questionnaire validated by experts was used, obtaining information from 320 people in 78 dwellings of between 2 and 11 inhabitants (M=4; SD=2) from 11 randomly selected blocks. Results: The prevalence of trauma in the sample was 8.1% (n=26); in 28.2% (n=22) of the dwellings visited, one (23.1%) or two (5.1%) persons were recorded with blows to the teeth. Conclusion: Dentoalveolar trauma, due to the frequency with which it occurs, is considered a dental emergency of utmost importance to keep the affected tooth and the tissues involved in the mouth; it is considered that the upper arch received more trauma and the most frequent causes were falls.

Nivel de información sobre protectores bucales y avulsión dentaria en entrenadores deportivos / Level of information on oral protectors and dental avulsion in sport trainers

Introducción: La práctica deportiva conlleva un alto riesgo de traumatismos dentoalveolares, por lo que es necesario que los entrenadores y deportistas conozcan sobre el uso adecuado de los protectores bucales y el procedimiento de urgencia ante la aparición de un trauma dental. Objetivo: Determinar el nivel de información sobre protectores bucales y avulsión dentaria en entrenadores deportivos. Métodos: Se realizó un estudio descriptivo de corte transversal, durante el mes de febrero de 2020, en la Escuela de Iniciación Deportiva Escolar Provincial Lino Salabarría Pupo de Sancti Spíritus. Para ello se seleccionó una muestra probabilística, representativa y aleatoria de 25 entrenadores de los deportes de combate y juego con pelotas, a los cuales se le aplicó una encuesta estructurada sobre protectores bucales y avulsión dentaria. Resultados: Entre los integrantes de la serie, 76 % eran universitarios y 52 % poseían más de 10 años de experiencia profesional. Asimismo, se obtuvo que 88 % recomendaran el uso del protector bucal a sus deportistas, pero la mayoría desconocía sus características, funciones y tipos, así como la conducta a seguir ante la ocurrencia de una avulsión dentaria. Conclusiones: El nivel de información sobre protectores bucales y avulsión dentaria en los entrenadores deportivos fue deficiente, lo que demostró que es necesaria la educación en dicho tema. De hecho, los estomatólogos tienen la tarea de realizar campañas para incentivar y educar en el uso de los protectores bucales y en el procedimiento correcto de urgencia si ocurriera un trauma dentoalveolar.

Introduction: The sport practice bears a high risk of dentoalveolar trauma, reason why it is necessary that trainers and sportsmen know on the appropriate use of oral protectors and the emergency procedure in view of the emergence of a dental trauma. Objective: To determine the level of information on oral protectors and dental avulsion in sport trainers. Methods: A descriptive and cross-sectional study was carried out during February, 2020, in the Lino Salabarría Pupo Provincial Initiation Sport School in Sancti Spíritus. A probabilistic, representative and random sample of 25 trainers from combat sports and ball games was selected, to whom an structured survey on oral protectors and dental avulsion was applied. Results: Among the members of the series, 76 % were university students and 52 % had more than 10 years of professional experience. Also, it was obtained that 88 % recommended the use of the oral protector to their sportsmen, but most of them ignored its characteristics, functions and types, as well as the way to behave considering the occurrence of a dental avulsion. Conclusions: The level of information on oral protectors and dental avulsion in the sport trainers was poor, what demonstrated that the education on this topic is necessary. In fact, dentists have the task of carrying out campaigns to motivate and educate in the use of oral protectors and in the correct emergency procedure in case a dentoalveolar trauma happened.

Traumatic injuries in primary dentition and their immediate and long-term consequences: a 10-year retrospective study from the State University of Rio de Janeiro, Brazil.

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.

Retrospective Analysis of Dento-alveolar Injuries at a Swiss University Clinic (2011-2015).

The aim of this study was to evaluate all dento-alveolar injuries occurring within a period of 5 years that were examined at the Department of Oral Surgery and Stomatology at the University of Bern. The case histories of 852 patients (522 males and 330 females) were assessed retrospectively. The mean age was 17 years and 9 months. The youngest patient was 10 months old, the oldest was 91 years old. Most accidents were recorded in the months of March and July. Friday was observed as the weekday when accidents were at their peak. 54% of trauma patients were first examined on the day of the accident. The most frequent causes of accident were falls, cycling or sports accidents. Injury types included concussion (72.4%), subluxation (14%) and luxation (7.7%). Crown fractures without pulp exposure were recorded in 522 teeth (10.7%). Rare types of trauma were crown fractures with pulp exposure (3.7%), and avulsion injuries (3.2%). The most frequently affected teeth were central incisors (40%), followed by lateral incisors (35.6%) and canines (19.5%). 71.5% of the patients with dento-alveolar trauma also had soft-tissue injuries (from abrasions to lacerations), mostly lip (51.6%), gingival (19%), and chin injuries (10.9%). The multivariate analysis showed that age had a significant impact on concussions, subluxations, intrusions, crown fractures, root fractures and non-oral injuries. For concussions and subluxations, the probability of an injury was the highest for the mixed dentition group. For intrusions, the probability of an injury decreased with age, but it was vice versa for crown fractures, root fractures and non-oral injuries. It was found that bicycle injuries had the highest injury probability for avulsions, luxations, subluxations, soft tissue - and non-oral injuries.

Traumatic dental injuries and pulp sequelae in an adolescent population.

BACKGROUND/AIMS: Traumatic dental injuries (TDI) occur frequently and may result in pulp sequelae. This includes pulp necrosis with infection, pulp canal obliteration and root resorption. The aim of this study was to assess the prevalence and risk factors of pulp sequelae after TDI among Norwegian adolescents. MATERIAL AND METHODS: A retrospective longitudinal study, including historical clinical data, was conducted with 16-year-old pupils in western Norway. All first-grade pupils, born in 1997 (n = 5184), attending public high schools, were invited to participate and to respond to an electronically administered closed-ended questionnaire (response rate 39.6%, n = 2055). Consent was given to access the dental records in the Public Dental Health Service in Hordaland, where information regarding TDI (diagnosis and treatment) and radiographs were interpreted. Only TDIs to anterior teeth were recorded (canine to canine in the maxilla and mandible). Outcome variables of TDI were registered and analysed using logistic regression, Kaplan-Meier survival estimates and log-rank test. RESULTS: The prevalence of TDI in the sample population was 16.4% (338 pupils), with a total of 637 teeth involved. The number of included teeth for analysis was 571 (90.5%). The prevalence of pulp necrosis with infection was 7.5%. Moderate and severe TDI was associated with a higher frequency of pulp necrosis with infection. Pulp canal obliteration and root resorption were found in 2.8% and 2.3% of teeth with TDI, respectively. Dental hard tissue injuries were more prone to the development of pulp necrosis than luxation injuries and combination injuries. The relationship between root development stage and development of pulp necrosis with infection was not statistically significant. CONCLUSIONS: Occurrence of different pulp sequelae among teeth affected with TDI was low. Moderate and severe TDI were more at risk of developing pulpal complications and hard tissue injuries were at higher risk of developing pulp necrosis with infection.

Complex Dentoalveolar Fractures: Main Clinical Variables Description and Analysis.

AIMS AND OBJECTIVES: To analyze and evaluate clinical features that define complex dentoalveolar trauma. MATERIALS AND METHODS: Forty-five patients, with a mean age of 36.1 years, were included in the study; most patients were male (82.2%). The main clinical features defining dentoalveolar fractures were evaluated, including the status of the tooth, alveolar socket and adjacent soft tissues and their relationships with tooth loss. The relationship between splinting and tooth loss was also studied. The data were analyzed using descriptive and statistical methods. RESULTS: A significant relationship was observed between the different clinical variables and tooth loss, in particular the status of the alveolar socket as the most relevant clinical factor; there was also a significant relationship between splinting and tooth loss, as this was the main protective factor. CONCLUSIONS: Tooth loss prognosis following complex dentoalveolar trauma is related to the clinical features of the fracture, particularly the status of the alveolar socket and the possibility of using splinting as treatment.

Awareness of Parents About the Emergency Management of Avulsed Tooth in Eastern Province and Riyadh.

Objective: To assess the level of parents knowledge about the emergency management of tooth avulsion in Eastern Province and Riyadh. Methods: A cross-sectional study was carried out by means of a questionnaire-based internet survey in which 1201 parents from Eastern Province and Riyadh participated. The questionnaire contained 10 closed-ended questions and was used to assess the knowledge of parents about the emergency management of avulsed teeth in Eastern Province and Riyadh. Chi-square test was used for data analysis. Results: In response to closed-ended questions, the statistically significant result was obtained for the history of child dental trauma in which 35% (P=0.04) of parents reported history of dental trauma in their children. These parents were belong to Eastern province (51%) and Riyadh (49%). Furthermore, only 31.3% of the parents were aware of possible storage media for transportation of avulsed tooth while 68.7% (49.5% in Eastern Province and 50.5% in Riyadh) were unaware (P=0.02) of it. Conclusion: That the majority of the parents were unaware of emergency management for tooth avulsion in two densely populated regions of Saudi Arabia. Education of parents should be initiated at a national level.

Tooth avulsion accidents due to urgent and emergency orotracheal intubation

BACKGROUND: Intubation is necessary during critical situations to reduce the risk of death. In Brazil, a need exists to determine the prevalence of tooth avulsions in emergency and urgent care. The objective of this study was to identify the causes of orotracheal intubation (OTI), the number of tooth avulsions, and the avulsed teeth that result from urgent and emergency intubation. MATERIAL AND METHODS: The sample consisted of 116 patients (total group) in intensive care units (ICUs) distributed across Group 1 (G1), which was composed of 71 patients from an urgent-care hospital, and Group 2 (G2), which was composed of 45 patients from an emergency hospital. Clinical examinations showed dental alveolus with signs of recent exodontia in the upper and lower anterior regions. Sociodemographic data and the reason for intubation were evaluated. The Shapiro-Wilk normality test, chi-square test, Fisher's exact test, Mann-Whitney U test, and univariate logistic regression were performed with a significance level of 5%. RESULTS: The avulsion prevalence was 4.3%, with more cases receiving emergency intubation (n = 4). All avulsions occurred in adults, and a significant difference (p = 0.011) was observed with regard to the elderly. A 1-year reduction in age increased the chance of tooth avulsion during intubation by 1.09 times; being female increased the chance by 2.88 times. CONCLUSION: Pulmonary problems were the major causes of intubation, with the highest tooth avulsion prevalence observed during emergency intubation. The avulsed teeth were 11, 12, 13, 22, 32, and 33 across all cases

Primeros auxilios en la avulsión dentaria. Conocimiento de profesores, entrenadores y padres / First aid measures in dentary avulsion. Knowledge of teachers, coaches and parents

INTRODUCCIÓN: La avulsión dentaria es el traumatismo dental más severo y grave requiriendo atención inmediata. Las medidas que se adoptan en los primeros momentos de la urgencia determinarán el pronóstico del diente afectado. OBJETIVO: Determinar el conocimiento de padres, profesores, personal no docente de colegios y entrenadores deportivos sobre los primeros auxilios que se deben adoptar ante una avulsión dental. METODOLOGÍA: El presente estudio analizó un total de 546 encuestas de padres, personal de centros de primaria y secundaria y entrenadores deportivos de la Comunidad de Madrid entre octubre de 2018 y febrero de 2019.Resultados y Discusión: El reimplante inmediato fue la opción elegida por el 0,8% de los encuestados (p= 0,001). Solo el 3,47% respondió que el diente avulsionado "debe cogerse por la corona, no cepillarse, guardarlo en leche, suero fisiológico o saliva del propio paciente y acudir a un dentista antes de una hora", medidas que pueden favorecer el pronóstico del diente reimplantado. CONCLUSIONES: Los padres, profesores, entrenadores y personal no docente de las escuelas no presentan la capacitación adecuada para actuar ante una avulsión dental

INTRODUCTION: Dental avulsion is the most severe and severe dental trauma and requires immediate attention. The measures adopted in the first moments of the emergency will determine the forecast of the piece. OBJECTIVE: Determine the knowledge that parents, teachers, non-teaching staff of schools and sports coaches have about the first aid that must be adopted in the event of a dental avulsion. METHODOLOGY: This study analyzed a total of 546 surveys of parents, staff of primary and secondary schools and sports coaches of the Community of Madrid between October 2018 and February 2019. Results and Discussion: Immediate reimplantation was the option chosen by 1% of the respondents (p= 0,001). Only 3,47% responded that the avulsed tooth "should by taken by the crown, not brushed, stored in milk, saline or saliva from the patient and go to a dentist within one hour" measures that may favor the prognosis of the reimplanted piece. CONCLUSION: Parents, teachers, coaches and non-teaching staff of the schools do not have the adequate training to act against a dental avulsión

How does orofacial trauma in children affect the developing dentition? Long-term treatment and associated complications.

Each year, millions of children are injured and live with the consequences of those injuries. Through infancy and childhood, orofacial trauma caused by falls or being struck by or against objects occurs in children. The long-term implications on the developing permanent teeth are little known, even when the oral region is the second most frequently injured body area in children under 6 years of age. During this period, the developing permanent teeth may be directly involved after trauma, causing mild to severe hypoplasia, displacement, damage to the tooth germ, or an extended range of morphofunctional disturbances. In some cases, the effects of oral and dental injuries caused by trauma appear later with the eruption of the permanent incisors when ectopic eruption, malalignments, and other developmental disturbances become visible. Therefore, long-term follow up of the patient in order to diagnose and treat associated complications becomes essential. Critical points for facing the consequences of orofacial trauma on the developing dentition are to recognize the impact of orofacial trauma in young children and the dentist's role in providing anticipatory guidance to parents and health care professionals, differentiate between mild and severe disturbances affecting the developing permanent teeth after oral injuries in early childhood, recognize the importance of follow-up controls, and recognize the importance of early referral to a pediatric dentist and orthodontist for diagnosis and treatment planning.

Traumatic dental injuries in preschool-age children: Prevalence and risk factors.

This study examined the prevalence, socio-demographic correlates, and clinical predictors of traumatic dental injuries (TDIs) in the primary dentition among a community-based sample of preschool-age children. The sample comprised 1,546 preschool-age children (mean age 49 [range: 24-71] months) in North Carolina public preschools, enrolled in a population-based investigation among young children and their parents in North Carolina. Information on socio-demographic, extraoral, and intraoral characteristics was collected and analyzed with bivariate and multivariate methods, including logistic regression modeling and marginal effects estimation. The prevalence of dental trauma was 47% and 8% of TDI cases were "severe" (pulp exposure, tooth displacement, discolored or necrotic tooth, or tooth loss). In bivariate analyses, overjet and lip incompetence were significantly associated with TDI. Overjet remained positively associated with severe trauma in multivariate analysis, OR = 1.4, 95% confidence interval (CI) [1.2, 1.6], corresponding to an absolute 1.3%, 95% CI [0.7, 1.8], increase in the likelihood of severe trauma, per millimeter of overjet. Children with increased overjet (>3 mm) were 3.8, 95% CI [2.0, 7.4], times as likely to have experienced severe TDI compared with those with ≤3 mm. Overjet is a strong risk factor for TDIs in the primary dentition. Incorporating and operationalizing this information may help TDI prevention and related anticipatory guidance for families of preschool-age children.

Changes in the epidemiology and aetiology of dental traumatic injuries in permanent teeth in children before and after German unification.

AIM: To evaluate the longitudinal occurrence of traumatic dental injuries in permanent teeth comparing recent data from 2014 to 2016 in Greifswald after German unification with a historic sample from socialist times (1974-1989). MATERIALS AND METHODS: In this retrospective study, traumatic dental injury parameters as type, date, location, and cause of injury as well as tooth affected were extracted from the trauma records of patients from 1974 to 1989 and 2014-2016. RESULTS: The descriptive analysis of 444 teeth in 245 patients revealed that the recent and historic samples had a very similar pattern of dental trauma (201/243 teeth in 117/128 patients, respectively): Maxillary permanent central incisors were affected in 70.7% and 68.3%, respectively. Enamel-dentine fractures were the most prevalent fracture injury in both recent and historic samples (64% and 43.1%, respectively) followed by enamel fractures (20.7% and 36.9%, respectively). Subluxations were the most common luxation traumatic dental injury (44.7%) followed by lateral luxation (39.8%) as reported in the historic sample while in the recent sample subluxation constituted 42.9% of luxation injuries followed by concussion (36.2%). CONCLUSION: This study detected a very stable pattern of dental traumatic injuries over 40 years, even after the change from a socialistic society to a market economy.

Atitudes imediatas dos praticantes de artes marciais frente à avulsão dentária / Immediate attitudes of martial arts practitioners against dental avulsion

Objetivo: O objetivo do presente estudo foi avaliar o nível de conhecimento dos praticantes de artes marciais da cidade de Juazeiro do Norte, Ceará, sobre avulsão dentária e como proceder mediante aos cuidados imediatos frente à ocorrência de avulsão dentária.Métodos: Um estudo transversal de carácter exploratório foi realizado com uma amostra de conveniência de 60 praticantes de artes marciais. As informações sobre avulsão dentária, experiências e condutas emergenciais frente a avulsão dentária e uso de protetores bucais e equipamentos de proteção foram coletadas através de um questionário autoaplicado. As análises dos dados envolveram estatísticas descritivas de frequência absoluta e relativa de todas as variáveis do estudo. Resultados: A média de idade dos participantes foi de 26,88 anos (DP ± 5,06), sendo 73,3% (n = 44) pertencentes ao sexo masculino. Do total de praticantes de artes marciais entrevistados, 48% praticavam Muay Thai e 18% Taekwondo. O estudo mostrou que apesar de 61,7% do total de entrevistados terem relatado saber o que era traumatismo dentário e 23,3% destes terem presenciado algum tipo de trauma dentário, 85,0% relataram não saber como proceder mediante os casos de avulsão. Entretanto, 95,0% consideraram esta informação como necessária para a prática de esportes. A maioria dos indivíduos praticantes de artes marciais (63,3%) relatou utilizar protetores bucais. Conclusão: A maioria dos praticantes de artes marciais entrevistados relatou saber o que o era traumatismo dentário, mas desconheciam como proceder diante dos casos de avulsão. A maioria dos entrevistados reconhecem a importância e afirmaram utilizar protetores bucais e equipamentos de proteção individual durante as práticas desportivas. (AU)

Aim:The present study sought to evaluate the level of knowledge of martial arts practitioners in the city of Juazeiro do Norte, Ceará, against dental avulsion and how to proceed through immediate care in the event of dental avulsion. Methods:A cross-sectional study was conducted with a convenience sample of 60 martial arts practitioners. Information on dental avulsion, experiences, and emergency behaviors against dental avulsion, as well as the use of mouth guards and protective equipment, were collected through a self-administered questionnaire. Data analysis involved descriptive statistics of the absolute and relative frequency of all variables in the study. Results: The mean age of the participants was 26.88 years (SD ± 5.06), of which 73.3% (n = 44) were males. Of the total number of martial arts practitioners, 48% practiced Muay Thai and 18% Taekwondo. The study showed that 61.7% of the respondents said they had knowledge about what dental trauma was, although only 23.3% had witnessed some type of dental trauma. In addition, 85.0% have never received guidance on how to proceed in cases of avulsion, but 95.0% consider this information to be necessary for the practice of sports. The majority of the individuals who practice martial arts (63.3%) use mouth guards. Conclusion: It was concluded that most of the martial arts practitioners interviewed in the present study do not have knowledge about dental avulsion and about the necessary immediate procedures in the event of dental avulsion. However, most of participants use mouth guards, wear personal protective equipment, and recognize the importance of these during sports practices. (AU)

Profile of intrusive luxation and healing complications in deciduous and permanent teeth - a retrospective study.

OBJECTIVE: This retrospective study analyse the profile of intrusion in deciduous (DT) and permanent teeth (PT), the occurrence of healing complications (HC), type of treatments and predisposing factors. METHODS: The records of patients attended from 2005 to 2011 were analysed. Records of patients who had one or more intruded DT or PT were included in the study. Data collected from dental records included age, gender, attendance (immediate/mediate), healing complications and type of treatment. A Chi-square test and Logistic regression (p ≤ .05) were performed to evaluate the associations between the type of teeth and presence of HC, as well as to explore the interactions between predisposing factors. RESULTS: The intrusion prevalence was 9.98% in DT and 2.45% in PT. Partial intrusion (57.3%) with palatal direction of the crown (61.8%) was most prevalent in DT, while complete intrusion (56.7%) with buccal direction of the crown (58.1%) was predominant for PT. Mobility was the most common HC in DT compared to root resorption in PT. Minimally invasive treatments were the most common therapy for DT compared to invasive treatments for PT. PT demonstrated increased HC when compared to DT (p = .004). A logistic regression illustrated that the level of intrusion and crown direction during the trauma did not influence the occurrence of HC (p > .05). CONCLUSION: Intrusion's profile in DT and PT are different. PT showed more HC than DT, however the level of intrusion and crown direction were not associated with the presence of HC.

A 12-Year Retrospective Study of Avulsion Cases in a Public Brazilian Dental Trauma Service.

This study assessed the epidemiological characteristics and management of the permanent teeth avulsion cases attended in a Brazilian dental trauma service from December 2005 to August 2016. A retrospective study was conducted of case records of 93 patients involving 139 avulsed teeth. Data included sex, age, trauma etiology, location of the accident, number and position of avulsed teeth, and presence and type of associated traumatic lesions. Management of the avulsed teeth was addressed as: time elapsed until teeth were retrieved from the accident's location; teeth's cleaning method and storage media; time elapsed until seeking treatment and replantation. The majority of the patients were children from 6-10 (31.2%) and 11-15 years old (26.9%). Male patients were more affected than female. Bicycle accident was the main etiological factor (31.2%). In 56 (60.2%) cases, traumatic lesions to neighboring teeth were present. In 55 (59.1%) cases, lesions to adjacent soft tissues were reported. In 82 (88.2%) cases, patients requested treatment at the same day of the accident. Sixty-four teeth (46.0%) were immediately retrieved and 28 (20.1%) were not found. Forty-two teeth (30.2%) were kept dry. Only one tooth (0.7%) was immediately replanted at the accident's site, while 51 teeth (36.7%) were not replanted. Numerous avulsed teeth were inappropriately managed and immediate replantation was not frequent. Public policies must be created to raise awareness towards the particularities of avulsion cases.
