Successful retreatment of a maxillary central incisor with a wide-open apex using MTA to fill the entire canal: 24-year follow-up.

Managing teeth with open apices can be a challenging scenario for clinicians. This case report describes the 24-year follow-up of a maxillary central incisor that failed to develop after a traumatic injury resulting in a wide-open apex. A 10-year-old girl presented complaining of discomfort in her upper teeth. Tooth #9 had received a traumatic blow several years before and was discoloured with a resin composite restoration on the mesio-incisal edge. The tooth was painful to percussion and palpation. An inadequate root canal filling and incomplete root formation were observed on the initial periapical radiograph. Root canal retreatment was initiated, and the canal filled entirely with mineral trioxide aggregate (MTA) because of the extremely wide canal and open apex. The patient was asymptomatic at the 24-year follow-up with the cone beam computed tomography and periapical radiographs demonstrating the stability of the MTA.

Pulp Canal Obliteration Following Traumatic Dental Injury in an Upper Lateral Incisor: A Case Report with 3-year Follow-up.

Endodontic management of teeth afflicted with pulp canal obliteration faces a challenge due to the heightened risk of complications including excessive wear, perforation, and suboptimal chemomechanical preparation. This report aims to elucidate the clinical endodontic strategy employed in addressing pulp canal obliteration after a history of dental trauma and an associated periradicular lesion in an upper lateral incisor. A patient visited the dental emergency department with symptoms of apical swelling, acute persistent pain, and discoloration of tooth 22. Following comprehensive clinical evaluation and cone-beam computed tomography, the diagnosis of pulp canal obliteration involving the cervical and middle thirds of the tooth, alongside an acute periradicular abscess was established. Root canal was accessed using tomographic image planning, augmented by loupe magnification and ultrasonic instrumentation. Precise identification of the access cavity was radiographically confirmed, preceded by thorough irrigation with 2.5% sodium hypochlorite and subsequent cervical and middle third preparation. Verification of the working length by an electronic apex locator ensured precise apical preparation, followed by passive ultrasonic irrigation to optimize disinfection and to enhance penetrability of intracanal calcium hydroxide medication, administered for 15 days to eliminate microbial invasion. Upon resolution of symptoms, root canal obturation employing thermo-mechanical compaction and coronal sealing with composite resin was accomplished. Radiographic assessment after a one-year interval presented evidence of lesion regression and bone repair. Subsequent cone-beam computed tomography imaging at the three-year follow-up confirmed complete healing of the periradicular tissues, attesting to the efficacy of the endodontic intervention.

The effect of sleep disorders, school jet lag, and anxiety in students 8-10 years of age on traumatic dental injuries.

BACKGROUND/AIM: Traumatic dental injuries (TDI) constitute a public health problem. The aim of the present study was to investigate whether sleep disorders, school jet lag, and anxiety are associated with TDI in schoolchildren 8-10 years of age. METHODS: An analytical, cross-sectional study was conducted with 739 pairs of parents/guardians and children enrolled in public and private schools. The parents/guardians answered a socioeconomic questionnaire, the Sleep Disturbance Scale for Children, Circadian Energy Scale, and Revised Children's Manifest Anxiety Scale. Four examiners underwent calibration exercises for the diagnosis of TDI (K > 0.80) using the criteria proposed by Andreasen (2007). A directed acyclic graph was used for the formulation of the theoretical model and statistical adjustments. Unadjusted and adjusted robust binary logistic regression analyses were performed (α = 5%). RESULTS: The prevalence of TDI was 16.2%. The following variables remained associated with the outcome in the final model: family income less than or equal to the minimum monthly wage (OR = 1.77; 95% CI: 1.09-2.88; p = .02), child's height >137.6 cm (OR = 1.68; 95% CI: 1.06-2.64; p = .02), the occurrence of school jet lag (OR = 2.12; 95% CI: 1.27-3.53; p = .004), anxiety (OR = 1.77; 95% CI: 1.04-3.00; p = .04) and sleep disorders (OR = 1.63; 95% CI: 1.38-1.93; p = .05). CONCLUSION: Children from families with a lower income, taller children, those with school jet lag, those with anxiety and those with sleep disorders had a greater occurrence of TDI.

Seeking treatment for traumatic dental injuries in schoolchildren: A multilevel analysis

ABSTRACT To investigate individual and contextual factors associated with seeking treatment for traumatic dental injuries. A cross-sectional study was conducted with 739 pairs of guardians and children. Guardians answered a questionnaire addressing sociodemographic characteristics, seeking treatment for a tooth injury in the child, and the Oral Health Literacy-Adult Questionnaire. Descriptive analysis and unadjusted and adjusted multilevel Poisson regression analysis (p<0.05). The prevalence of seeking treatment for traumatic dental injury was 44.7%. Sociodemographic variables associated were white skin of the child (PR = 1.30; 95% CI: 1.08-1.76), mother's age older than 35 years (PR = 1.70; 95% CI: 1.50-1.90), married parents (PR = 1.93; 95% CI: 1.70-2.23), guardians with more than eight years of schooling (PR = 2.00; 95% CI: 1.76-2.23), with adequate oral health literacy (PR = 3.33; 95% CI: 3.01-3.62) and the daily use of electronic devices by the child (PR = 1.26; 95% CI: 1.02-1.50). On the contextual level, attending a private school (PR = 1.77; 95% CI: 1.02-3.05) and the number of primary care units with oral health teams in the school district (PR = 1.78; 95% CI: 1.12-2.38) remained associated. Among the children who suffered TDI, adequate oral health literacy on the part of the parents stood out among the factors associated with seeking treatment.

Resumo Investigar fatores individuais e contextuais associados à busca de tratamento para lesões dentárias traumáticas. Foi realizado um estudo transversal com 739 pares de responsáveis e crianças. Os responsáveis responderam a um questionário abordando características sociodemográficas, busca por tratamento para traumatismo dentário na criança e o Questionário de alfabetização em saúde bucal para adulto. Análise descritiva e análise de regressão de Poisson multinível não ajustada e ajustada (p<0,05) foram realizadas. A prevalência de busca de tratamento para lesão dentária traumática foi de 44,7%. As variáveis sociodemográficas associadas foram a pele branca da criança (RP = 1,30; IC 95%: 1,08-1,76), idade da mãe maior que 35 anos (RP = 1,70; IC 95%: 1,50-1,90), os responsáveis casados (RP = 1,93; IC 95%: 1,70-2,23), com mais de oito anos de estudo (RP = 2,00; IC 95%: 1,76-2,23), com alfabetização adequada em saúde bucal (RP = 2,00; IC 95%: 1,76-2,23) e uso diário de dispositivos eletrônicos pela criança (RP = 1,26; IC 95%: 1,02-1,50). No nível contextual, frequentar uma escola particular (PR = 1,77; IC 95%: 1,02-3,05) e a quantidade de unidades básicas de saúde com equipes de saúde bucal no distrito sanitário da escola (PR = 1,78; IC 95%: 1,12-2,38) permaneceram associados. Entre as crianças que sofreram TDI, a alfabetização em saúde bucal adequada dos pais foi um fator que se destacou na busca por tratamento.

Association of the prevalence and severity of untreated traumatic dental injuries with body mass index among Brazilian preschool children.

BACKGROUND/AIM: Children with excess weight may be more predisposed to traumatic dental injuries (TDI). The aim of this study was to investigate the association between overweight/obesity and TDI presence and severity in Brazilian preschool children. MATERIAL AND METHODS: A cross-sectional study was conducted of 347 children aged three to five years. The main exposure was evaluated based on the body mass index (BMI). Socioeconomic-demographic characteristics and harmful oral habits were investigated using a questionnaire sent to the parents/guardians. Oral clinical examinations were performed to determine overjet (criteria proposed by Foster and Hamilton), and the presence and severity of TDI (criteria proposed by Andreassen). Descriptive statistics were performed. Univariate and multivariate Poisson regression analyses were conducted for each outcome. RESULTS: The prevalence of TDI in the sample was 41.5% and 16% of the children had enamel and dentin fractures. In the multivariate analysis, BMI and overjet were associated with the presence and severity of TDI (PR: 2.04 and 1.78, respectively) of TDI (PR: 2.27 and 2.24, respectively) (p < .001 for all associations). CONCLUSION: Overweight/obesity was associated with both the presence and severity of TDI in early childhood.

Association between obesity and traumatic dental injuries in pre-school children-A case-control study.

BACKGROUND/AIM: Obese children are more prone to accidents due to poorer motor skills which increase the likelihood of falls and the occurrence of traumatic dental injuries (TDIs). The aim of this study was to determine the association between overweight/obesity and TDI in pre-school children. MATERIAL AND METHODS: The case group was formed by children with TDI identified during a clinical examination (n = 262). Each pre-school child identified as a case was matched by a peer of the same age, gender and pre-school but without TDI to form the control group (n = 262). TDI was evaluated using the criteria proposed by Andreasen. The weight and height of the children were measured for the calculation of the body mass index which was plotted on the growth curve established by the World Health Organization. Socio-demographic variables were collected through questionnaires sent to the parents/guardians. Data analysis involved the determination of frequency distribution, the chi-square test and logistic regression analysis. RESULTS: The sample was composed of 253 children in each group. Among the children in the case group, 15.4% (n = 39) were overweight and 15.8% (n = 40) were obese. In the control group, 13.8% (n = 35) were overweight and 8.3% (n = 21) were obese. Children with trauma were more likely to be obese than children without trauma (OR = 2.05; 95%CI: 1.14 to 3.67; p = .016). In contrast, TDI was not associated with being overweight. A greater odds of TDI was also associated with an open bite (OR = 3.61; 95% CI: 1.64 to 7.96; p = .001) and accentuated overjet (OR = 2.19; 95% CI: 1.37 to 3.50; p = .001). CONCLUSIONS: Pre-school children with a history of dental trauma were more likely to be obese than those without a history of dental trauma whereas being overweight was not associated with TDI.

Impact of traumatic dental injury treatment on the Oral Health-Related Quality of Life of children, adolescents, and their family: Systematic review and meta-analysis.

BACKGROUND/AIM: Measures of oral health-related quality of life (OHRQoL) are useful in clinical trials to evaluate treatment outcomes. To detect the treatment impact of traumatic dental injuries (TDI) on OHRQoL is extremely relevant. The aim of this study was to assess whether there is scientific evidence of the impact of TDI treatment on OHRQoL of children, adolescents, and their families. MATERIAL AND METHODS: A systematic review and meta-analysis were conducted selecting articles from PubMed, Web of Science, Scopus, Cochrane Library, and Virtual Health Library until May 22nd, 2020. The gray literature, clinical trial registers, and a manual search were performed. Two independent reviewers selected the studies, extracted the data, and assessed the ROBINS-I risk of bias. A meta-analysis was performed using RevMan 5.4 program. The certainty of the evidence was evaluated using the GRADE system. RESULTS: In the electronic search, 413 abstracts and one registered study were found. After removing the duplicates and eligibility application, six studies were included. Individually, the studies presented low to moderate risk of bias and they found that TDI treatment reduces the negative impact on OHRQoL. In the meta-analysis, TDI treatment improved OHRQoL for 8- to 10-year-old children (p = .03; CI 5.19 [0.62, 9.75]) (detected by CPQ 8-10 questionnaire). In the perception of parents, the children, and adolescents who had suffered TDI also had their OHRQoL improved (p = .04; CI 14.77 [0.95, 28.60]) (detected by PPQ and P-CPQ questionnaire) but both evaluations had very low certainty of evidence. CONCLUSION: Treatment of traumatic dental injuries reduces the impact on the OHRQoL of children and adolescents. However, more studies are necessary to detect the TDI treatment influence on OHRQoL of preschoolers and in the family as well to estimate the effects due to outcomes that had a very low certainty of evidence (#CRD42018091210).

The impact of traumatic dental injury on sensory perception and oral health-related quality of life of a child/adolescent before and after the treatment with aesthetic prosthesis: case report.

Children and adolescents are most frequently affected by Traumatic Dental Injuries (TDIs). Scientific evidence shows that TDIs have a negative impact on the oral health-related quality of life (OHRQoL) of children/adolescents and their families. This article aimed to report two cases of avulsion and how the treatment influenced the oral sensory perception and OHRQoL. Two patients (8 and 14 years) from a "Dental Trauma Care Program" (DTCP) presenting avulsion were evaluated. The stereognosis test assessed oral sensory perception. This test obtains the average of right and wrong answers, as well as the time spent to perceive 6 silicone objects with different geometric shapes. Child Perceptions Questionnaire (CPQ) was applied to evaluate the OHRQoL through interviews. Based on the two reports, it was possible to observe a satisfactory improvement in the OHRQoL of the child/adolescent and their families. TDI influenced negatively the oral sensory perception of both patients. Since the aesthetic prosthesis did not entirely improve the patients' oral tactile perception, it may be considered a temporary solution.

Oral health outcomes: the association of clinical and socio-dental indicators to evaluate traumatic dental injury profile in low income Brazilian children.

OBJECTIVE: To use clinical and socio-dental indicators to evaluate traumatic dental injury (TDI) profile in Brazilian preschool children with low income. METHODS: A cross-sectional study was carried out with children of low-income families, from 2 to 6 year-old, who attended public preschools. A clinical indicator to evaluate TDI and a socio-dental indicator to detect the impact on Oral Health-Related Quality of Life (OHRQoL) for preschoolers (Early Childhood Impact Scale - ECOHIS) were used. Impact means were obtained, and the chi-square test and odds ratio were used in order to evaluate the variables (P<0.05). RESULTS: Of the 606 children evaluated, the results were obtained from a final sample of 446 children. The prevalence of TDI was 17%. Children from 37 to 60 months (P=0.04; OR=0.59 95% CI 0.34-1.01) were associated with TDI. The mean impact on OHRQoL in the group with or without TDI was low without a statistical difference (P=0.97). CONCLUSION: Based on these findings, the association of clinical and socio-dental indicators showed low prevalence of TDI and the impact on OHRQoL was indifferent between groups with or without TDI.

Impact of complicated and uncomplicated traumatic dental injuries on oral health-related quality of life of preschoolers and their family.

The severity of a traumatic dental injury (TDI) can influence the prognosis of deciduous teeth and the formation of permanent successors. Consequently, it can have a negative influence on the daily lives of children and their parents. The present study aimed to evaluate the impact of complicated and uncomplicated TDI on the oral health-related quality of life (OHRQoL) of preschoolers and their families. A cross-sectional study was carried out according to the Strengthening the Reporting of Observational Studies in Epidemiology guidelines. After sample calculation and application of the eligibility criteria, 76 children from public preschools (aged 2 to 5 years) with TDI were selected during a period of 5 months. TDI was diagnosed using the Dental Trauma Index and classified according to the severity as complicated or uncomplicated. The Brazilian version of the Early Childhood Oral Health Impact Scale (ECOHIS) was used to determine OHRQoL. The Poisson regression model and Poisson regression model with robust estimates were calculated according to p-values <0.05. The complicated group and the uncomplicated group presented low average impact according to ECOHIS scores and there was no significant difference in the total scale, subscale, and domains (P>0.05) according to the type of TDI. Based on these findings, it can be concluded that severity of TDI did not influence the OHRQoL of preschoolers and their families.

Epidemiology of facial fractures: incidence, prevalence and years lived with disability estimates from the Global Burden of Disease 2017 study.

BACKGROUND: The Global Burden of Disease Study (GBD) has historically produced estimates of causes of injury such as falls but not the resulting types of injuries that occur. The objective of this study was to estimate the global incidence, prevalence and years lived with disability (YLDs) due to facial fractures and to estimate the leading injurious causes of facial fracture. METHODS: We obtained results from GBD 2017. First, the study estimated the incidence from each injury cause (eg, falls), and then the proportion of each cause that would result in facial fracture being the most disabling injury. Incidence, prevalence and YLDs of facial fractures are then calculated across causes. RESULTS: Globally, in 2017, there were 7 538 663 (95% uncertainty interval 6 116 489 to 9 493 113) new cases, 1 819 732 (1 609 419 to 2 091 618) prevalent cases, and 117 402 (73 266 to 169 689) YLDs due to facial fractures. In terms of age-standardised incidence, prevalence and YLDs, the global rates were 98 (80 to 123) per 100 000, 23 (20 to 27) per 100 000, and 2 (1 to 2) per 100 000, respectively. Facial fractures were most concentrated in Central Europe. Falls were the predominant cause in most regions. CONCLUSIONS: Facial fractures are predominantly caused by falls and occur worldwide. Healthcare systems and public health agencies should investigate methods of all injury prevention. It is important for healthcare systems in every part of the world to ensure access to treatment resources.

Acting and knowledge of emergency rescue teams in dental trauma / Atuação e conhecimento de equipes de resgate de emergência em casos de trauma dental

Objetivo: O traumatismo dentário é regularmente freqüente em pacientes atendidos por equipes de resgate em locais de acidentes e por equipes de emergência em hospitais. No entanto, esses profissionais recebem pouca ou nenhuma informação sobre como cuidar e atuar em casos de lesões traumáticas em tecidos duros e moles. O objetivo deste estudo foi avaliar o nível de conhecimento dos profissionais das equipes de resgate e emergência (médicos, enfermeiros e paramédicos) sobre o atendimento do traumatismo dentário. Material e métodos: 196 profissionais das unidades de resgate e emergência receberam um questionário padronizado de 5 questões referentes ao atendimento do traumatismo dentário e preservação de tecido dentário avulsionado (um dente ou seu fragmento). Resultados: os resultados mostraram um alto nível de atendimento de pacientes de traumatismo dentário por paramédicos, enfermeiros e médicos, com conhecimento muito baixo sobre como lidar com esses casos, e com resultados moderados sobre o melhor meio para preservar o dente avulsionado, e as ações tomadas durante o processo de resgate. Conclusão: há uma alta ocorrência de casos de traumatismos dentários atendidos por equipes de resgate e emergência, com falta de conhecimento, o que sugere a necessidade de mais campanhas educativas para esses profissionais com acompanhamento a longo prazo.

Traumatismo orofacial em crianças e adolescentes e fatores associados / Orofacial trauma in children and adolescents and factors associated

Objetivou-se estudar o traumatismo orofacial em crianças e adolescentes por meio da avaliação de(a): (I) fatores clínicos, características individuais e fatores ambientais relacionados à saúde bucal na qualidade de vida de crianças e adolescentes; (II) literatura sobre os fatores de risco para os Traumatismos dentários (TD) na população brasileira; (III) evidências científicas que suportem a presença de cárie dental como um fator predisponente aos TD; (IV) frequência e dos fatores predisponentes ao TD nos dentes decíduos (DD); (V) intrusões, ocorrência de sequelas, tratamentos e fatores predisponentes; (VI) injúrias aos tecidos moles decorrentes de traumatismo orofacial em crianças e adolescentes; (VII) conhecimento dos responsáveis e pacientes, entre 9 e 15 anos, sobre protetores bucais. Foram confeccionados 2 revisões, sendo uma narrativa e outra sistemática e 5 estudos observacionais. Os resultados encontrados foram: (I) qualidade de vida é influenciada direta e indiretamente por características ambientais, pela saúde bucal e pelas características individuais dos pacientes; (II) fatores de risco para TD no Brasil são semelhantes aos de outras populações, no entanto não existe um consenso sobre a predisposição por gênero e fatores socioeconômicos nos DD; (III) a cárie teve uma correlação positiva com TD em dentes permanentes (DP) (OR=1,490; 95%, IC:1,209­1,835; p<0.001) e uma correlação negativa em DD (OR=0,706; 95%, IC:0,550­0,906; p=0.006); (IV) A fratura de esmalte / dentina com exposição da polpa (n = 51) e intrusão (n = 131) foram as lesões mais comuns no tecido dentário e de suporte, respectivamente. Meninas (OR= ,822; IC=1,050-3,164; p=0,033) na faixa etária de 4­6 anos (OR = 2,15; IC =1,239­3,747; p=0,007) possuíram mais chances de sofrer concussão. Crianças, entre 4-6 anos, possuem menor chance de sofrer intrusão (OR=0,496; IC=0,278­0,886; p=0,018); (V) DP possuem significativamente mais sequelas do que DD (p=0,004), além disso, o nível de intrusão e a direção da coroa não influenciaram a ocorrência de sequelas (p>0,05); (VI) Meninos (65,6%) e crianças de 0 a 3 anos (39,7%) apresentaram mais lesões em tecidos moles. A busca pelo cuidado imediato foi estatisticamente influenciada pela presença dessas injúrias (p <0,05); (VII) 54,9% dos cuidadores não sabiam o que era um protetor bucal e nenhum dos adolescentes entrevistados utiliza protetor bucal durante atividade esportiva. Conclui-se que a qualidade de vida é influenciada direta e indiretamente por características ambientais, pela saúde bucal e pelas características individuais dos pacientes; os fatores de risco para o Brasil são semelhantes aos encontrados ao redor do mundo, com exceção do gênero e fatores socioeconômicos para DD; a cárie possui uma relação positiva com TD nos DP e negativa com os DD; o gênero e a idade são considerados fatores de risco para concussão e intrusão nos DD; o nível de intrusão e deslocamento da coroa não influenciaram as sequelas, porém DP possuem mais sequelas do que DD; as injúrias aos tecidos moles influenciou a busca por cuidado imediato, sendo mais frequentes em meninos e crianças mais novas; cuidadores e adolescentes possuem pouco conhecimento sobre protetores bucais.

This study aimed to study orofacial trauma in children and adolescents by evaluating (a): (I) clinical factors, individual characteristics and environmental factors related to oral health in the quality of life of children and adolescents;; (II) literature on the risk factors for dental trauma (DT) in the Brazilian population; (III) scientific evidence to support the presence of dental caries as a predisposing factor to DT; (IV) frequency and factors predisposing to DT in primary teeth (pT); (V) intrusions, occurrence of sequels, treatments and predisposing factors; (VI) soft tissue injuries due to orofacial trauma in children and adolescents; (VII) knowledge of those responsible and patients, between 9 and 15 years, on mouth guards. Two reviews were made, one narrative and one systematic and five observational studies. The results were: (I) quality of life is influenced directly and indirectly by environmental characteristics, oral health and individual characteristics of patients; (II) risk factors for DT in Brazil are similar to those of other populations, however, there is no consensus on the predisposition for gender and socioeconomic factors in pT; (III) caries had a positive correlation with TD in permanent teeth (PT) (OR = 0.496, 95%, CI: 1.209-1.835, p <0.001) and a negative correlation in pT (OR = 0.706, 95%, CI 0.550-0.906, p = 0.006); (IV) Enamel/dentine fracture with pulp exposure (n=51) and intrusion (n=131) were the most common injuries of dental and support tissues, respectively. Girls (OR = 822, CI = 1.050-3.164, p = 0.033) in the 4-6 year age group (OR = 2.15, CI = 1.239- 3.747, p = 0.007) were more likely to suffer concussion; (V) PT have significantly more sequelae than pT (p = 0.004), in addition, the level of intrusion and the direction of the crown did not influence the occurrence of sequelae (P> 0.05); (VI) Boys (65.6%) and children 0-3 years old (39.7%) had more soft tissue lesions. The search for immediate care was statistically influenced by the presence of these injuries (p <0.05); (VII) 54.9% of caregivers did not know what a mouthguard was, and none of the adolescents interviewed used a mouthguard during sports activities. It is concluded that the quality of life is influenced directly and indirectly by environmental characteristics, oral health and individual characteristics of patients; The risk factors for Brazil are similar to those found around the world, except for gender and socioeconomic factors for pT; Caries has a positive relationship with DT in PT and negative with pT; Gender and age are considered risk factors for concussion and intrusion in pT; The level of intrusion and displacement of the crown did not influence the sequelae, but DP had more sequelae than pT; The soft tissue injuries influenced the search for immediate care, being more frequent in boys and younger children; Caregivers and adolescents have little knowledge about mouth guards.

Trauma dental e protetor bucal: conhecimento e atitudes em estudantes de graduação em Educação Física / Dental trauma and mouthguard: knowledge and attitudes in Physical Education undergraduates

Resumo Este estudo objetivou avaliar o conhecimento e as atitudes de estudantes de Educação Física de Universidades públicas do Estado do Rio de Janeiro, Brasil, em relação ao traumatismo dentário e uso de protetor bucal. Foram entrevistados 373 graduandos de três universidades públicas do Rio de Janeiro, através de questionário semiestruturado e padronizado. Os dados foram tabulados e analisados (SPSS 16.0), sendo obtida a frequência (%) e a relação dos mesmos (Teste qui-quadrado, p < 0,05). Apenas 3,21% dos entrevistados haviam recebido informação sobre traumatismo dentário e utilização do protetor bucal durante a graduação. Com relação à atitude dos graduandos, responderam corretamente apenas 19,83% a conduta frente a uma avulsão; 54,69% ao manuseio do dente avulsionado e 7,77% ao transporte do dente avulsionado. Ao se comparar essas atitudes em razão do período de graduação (< 5º período ou ≥ 5º período), informações prévias de trauma e experiências prévias de trauma, não se observou diferença significativa (p > 0,05). Tratando de prevenção, 89,81% conheciam o protetor bucal, embora apenas 17,96% o utilizavam durante atividades esportivas. Conclui-se que os alunos não recebem tais informações durante a graduação, mesmo possuindo em sua grade curricular a disciplina de primeiros socorros. Cabe aos cirurgiões dentistas desenvolver ações para que este conhecimento supra as necessidades dos futuros profissionais de educação física.(AU)

Abstract To evaluate the knowledge and attitudes in a group of Brazilian physical education undergraduate students, relative to dental trauma and use of mouthguard. A total of 373 undergraduates from three public universities of Rio de Janeiro were interviewed by means of a semi-structured standardised questionnaire. The data were tabulated and analyzed using the statistical program SPSS, 17.0. Frequency was performed and it was also applied the qui-quadrado (p < 0.05) test, to establish a relation between variables of interest. Only 3.21% of the interviewees had been given information on dental trauma and use of mouth protector during their undergraduate course. With regard to their attitudes, only 19.83% responded correctly about how to act towards a tooth avulsion; 54.69% about how to manage the avulsed tooth, and 7.77% about how to transport the avulsed tooth. By comparing these attitudes in relation to the undergraduate period (before or after the 5th semester), previous information and experience on dental trauma, it was observed no significant difference (p > 0.05). With regard to prevention, 89.81% knew mouthguard although only 17.96% wore it during sport activities. The students were given no information during their undergraduation course, even though the curriculum has the discipline of first aid. The dentist are supposed to develop actions so that such knowledge meets the needs of the future physical education practitioners.(AU)

Tooth injury in anaesthesiology / Lesão dentária na anestesiologia

BACKGROUND AND OBJECTIVES: Dental injury is the most common complication of general anaesthesia and has significant physical, economic and forensic consequences. The aim of this study is to review on the characteristics of dental injury associated with anaesthesiology and existing methods of prevention. CONTENTS: In this review, the time of anaesthesia in which the dental injury occurs, the affected teeth, the most frequent type of injury, established risk factors, prevention strategies, protection devices and medico-legal implications inherent to its occurrence are approached. CONCLUSIONS: Before initiating any medical procedure that requires the use of classic laryngoscopy, a thorough and detailed pre-aesthetic evaluation of the dental status of the patient is imperative, in order to identify teeth at risk, analyze the presence of factors associated with difficult intubation and outline a prevention strategy that is tailored to the risk of dental injury of each patient.

JUSTIFICATIVA E OBJETIVOS: A lesão dentária é a complicação mais comum da anestesia geral e apresenta importantes consequências físicas, econômicas e médico-legais. O objetivo deste estudo é fazer uma revisão sobre as características da lesão dentária associada a anestesiologia e os métodos de prevenção existentes. CONTEÚDO: Nesta revisão são abordados o momento da anestesia em que a lesão dentária ocorre, os dentes acometidos, o tipo de lesão mais frequente, os fatores de risco estabelecidos, as estratégias de prevenção, os dispositivos de proteção e as implicações médico-legais inerentes à sua ocorrência. CONCLUSÕES: Antes de iniciar qualquer procedimento médico que exija o recurso à laringoscopia clássica é imperativa uma avaliação pré-anestésica minuciosa e detalhada do estado dentário do doente, de forma a identificar os dentes em risco, analisar a presença de fatores associados a dificuldades de intubação e delinear uma estratégia de prevenção que seja adaptada ao risco de lesão dentária de cada doente.
