Interpersonal violence in a city of Paraná: a study about the epidemiological profile of victims and characterization of dental trauma / Violência interpessoal em cidade paranaense: um estudo do perfil epidemiológico das vítimas e caracterização dos traumas dentais

The socioeconomic context and population vulnerability are directly associated with violence in the country. In Brazil, the Criminal Code provides the illicit act and punishes the aggressor who offends the physical aggression from a person. Interpersonal violence is an illegal act and is associated with the vulnerability of victims. Therefore, the study of the epidemiological profile of victims of interpersonal violence is needed to alert the population about their susceptibility. The present study aimed to design the epidemiological profile of victims of bodily injury from interpersonal violence in the region of Maringá, in the state of Paraná, and to study the characterization of dental injuries in terms of permanent weakness and deformity. Four thousand nine hundred sixty-two reports performed between 2018 and 2020 were analyzed using descriptive statistics. Data collected included: sex, age, marital status, the region affected by the bodily injury, type of dental trauma, and responses to "weakness" or/and "permanent deformity". During the period studied, there was a prevalence of female victims (57.8%), white skin color (80.2%), aged between 21 and 30 years (24.9%), single (54.9%), and the most affected region was the upper limbs (32.1%). Regarding bodily injuries with dental involvement, 67 cases were reported, male victims were prevalent (60.3%), and dental fracture was highlighted with 54.4% of examined injuries.The implementation of the Forensic Dentistry Centre took place in August 2019 at the Medico-Legal Institute of Maringá. Also, with the interruption of expert activities in 2020 - due to the COVID-19 pandemic ­ relevant outcomes regarding permanent weakness were observed. The epidemiological profile of victims is characterized by the female sex, white skin color, the age group from 21 to 30 years old, and singles. Regarding dental trauma, male victims, and dental fractures were prevalent. Furthermore, there was an increase in the classification of "permanent weakness", as well as a slight increase in cases of "further assessment required" for permanent deformity (AU).

O contexto socioeconômico e a vulnerabilidade da população estão diretamente associados à violência no país. No Brasil, o Código Penal (CP) prevê o ato ilícito e pune o agressor que atentar contra a integridade física de outrem. A violência interpessoal constitui um ato ilícito e está associada à vulnerabilidade das vítimas. Sendo assim, o estudo do perfil epidemiológico de vítimas de violência interpessoal se faz necessário para alertar a população quanto à suscetibilidade dessas. O presente estudo objetivou traçar o perfil epidemiológico de vítimas de lesão corporal por violência interpessoal na região de Maringá, no estado do Paraná, e estudar a caracterização das lesões dentais quanto à debilidade e deformidade permanente. Foram analisados 4.962 laudos pertencentes aos anos de 2018 a 2020 por estatística descritiva. Dados coletados incluíram: sexo, idade, estado civil, região afetada pela lesão corporal, tipo de trauma dental e respostas para "debilidade" ou/e "deformidade permanente". Durante o período estudado, houve prevalência de vítimas do sexo feminino (57,8%), cor de pele branca (80,2%), com idade entre 21 e 30 anos (24,9%), solteiros (54,9%), e a região mais afetada foi a dos membros superiores (32,1%). Em relação às lesões corporais com envolvimento dental, 67 casos foram relatados. Vítimas do sexo masculino foram prevalentes (60,3%) e a fratura do elemento obteve destaque com 54,4% das lesões periciadas. A implementação do Núcleo de Odontologia Legal ocorreu em agosto de 2019 e, ainda com a interrupção das atividades periciais no ano de 2020 ­ devido à pandemia da COVID-19 ­ resultados quanto à debilidade permanente foram evidentes. O perfil epidemiológico das vítimas é caracterizado pelo sexo feminino, cor de pele branca, faixa etária de 21 a 30 anos e solteiros. Quanto aos traumas dentais, vítimas do sexo masculino e fraturas dentais foram prevalentes. Além disso, houve um aumento na classificação de "debilidade permanente", bem como um leve aumento nos casos de "necessidade de avaliação complementar" para deformidade permanente (AU).

Dental trauma and oral health-related quality of life among 7th-grade students of public elementary schools

Dental trauma is a public health problem because of its high prevalence rates and treatment costs and for affecting mainly younger individuals. Aim: This cross-sectional study aimed to investigate the variables associated with dental trauma and its influence on oral health-related quality of life among 7th-grade students of public elementary schools. Methods: The data was collected with semi-structured and self-administered questionnaires and an intraoral clinical examination (n = 204). The variables collected regarded dental trauma, lip coverage, overjet, oral health-related quality of life (Child Perceptions Questionnaire - CPQ11-14 ISF: 8), and sociodemographic profile. Association tests and the Mann-Whitney test were performed at a 5% significance level. Results: Dental trauma occurred in 12.3% of students, 94.6% had adequate lip coverage, and the mean overjet was 2.7 mm (±2.0). Sex was the only variable with a statistically significant association with dental trauma (p = 0.021). There was no statistically significant difference in the CPQ11-14 ISF: 8 score between students with and without dental trauma (p = 0.136). Conclusions: Dental trauma was significantly associated with sex and did not impact the oral health-related quality of life of the students

This retrospective observational study aimed to analyze cases assisted at the Dentoalveolar Trauma Clinic of the School of Dentistry of the Federal University of Rio Grande do Sul (FO-UFRGS) from March 2015 to March 2018, according to the treatments performed on traumatized permanent teeth and the results after one year of follow-up. The sample was based on information collected from clinical records of 92 patients, referring to a) data before treatment, b) data on the diagnosis and proposed treatment, and c) data on the follow-up period. Descriptive and inferential statistical analyses were performed. Most patients were male (56.5%) and aged six to 11 (30.4%) and older than 18 (29.1%) years. The prevalent cause of trauma was falling, and 59% of patients were first assisted within 24 hours. The most frequent traumas were enamel and dentin fractures with and without pulp exposure (6.3%), lateral luxation (1.4%), and avulsion (1.9%). Endodontic treatment was usually performed on traumatized teeth (7.2%). Of the 92 patients, 58 returned for maintenance visits with a mean follow-up of one year. Most patients had successful treatments. Prompt care and patient follow-up were essential for the good prognosis of traumatized teeth.(AU)

Clinical analysis of children and adolescents emergency dental trauma cases / 北京大学学报(医学版)

OBJECTIVE@#To analyze the etiological and clinical characteristics of oral emergency patients under 18 years with dental trauma, and to provide guidance on the prevention and treatment in children and adolescents.@*METHODS@#A retrospective study on the intact data of the dental trauma patients under 18 years from January 2016 to December 2018 in the Department of Oral Emergency in Peking University School of Stomatology was conducted, and the distribution of the patients' gender, age and visiting time, as well as the number and position of traumatic teeth, diagnostic classification, and multiple injury with dental trauma were analyzed.@*RESULTS@#During the period, 54.2% of the first visit dental trauma patients (10 164) were children or adolescents (5 506). The two peak ages were 3-4 and 7-9 years. The incidence of the male was higher than the female in every age group (Wilcoxon test, P < 0.001). From May to June and September to November, there were more cases of dental trauma. The peak time of daily dental trauma cases was from 19:00 to 20:00 (Jonckheere-Terpstra test, P < 0.001). The positions of traumatic teeth in both sides were approximate symmetrical, and maxillary central incisors were the most affected. 52.3% of the patients suffered multiple teeth injuries. Among the permanent teeth trauma, enamel and dentin fracture was the most common (24.7%), followed by concussion (20.5%), sub-luxation (17.9%) and complicated crown fracture (14.4%). And among the primary teeth trauma, subluxation was the most common (31.1%), followed by concussion (14.5%) and lateral luxation (9.5%). 19.7% of the children and adolescent dental trauma patients were also suffered maxillofacial soft or hard tissue injury.@*CONCLUSION@#The incidence of dental trauma in children and adolescents is higher than that in adults. There were two age peaks among the children and adolescents patients. Primary teeth and young permanent teeth were usually suffered. Clinical treatment should be considered along with the characteristics of child tooth growth. In order to prevent the occurrence of dental trauma, early orthodontic intervention should be carried out in children with severe overjet. Families, schools and nursery institutions should strengthen the protection against dental trauma.

Prevalence and Associated Factors of Dental Trauma in Six-Year-Old School-Children

ABSTRACT Objective: To estimate the prevalence and associated factors of dental trauma in 6-year-old school children in the city of Palhoça, Brazil. Material and Methods: Cross-sectional study nested in a cohort study. It involved a representative sample of school children born in 2009, residing in the municipality and regularly enrolled in public and private schools (n = 1,102). Clinical data were obtained through oral exams. To evaluate the incisal overjet, the distance in millimeters was measured horizontally from the labial surface of the lower central incisor to the labial surface of the upper incisor. Bivariate analyses were performed using the Chi-square test, with a p-value <0.05 considered statistically significant. Multivariate analyses using Poisson Regression were performed to identify independent associations between the prevalence and the independent variables studied. Results: Prevalence of dental trauma was 4.2% (95% CI 3.0-5.4). Dental trauma was statistically associated with studying in a private school (PR = 1.03; 95% CI 1.01-1.06) (p=0.016) and with inadequate lip coverage (PR = 1.08; 95% CI 1.01-1.14) (p=0.016). Conclusion: The prevalence of 4.2% of dental trauma in six-year-old children, associated with inadequate and greater lip coverage in children from private schools should be taken into account, since most teeth at this stage are newly erupted.

Prevalence of facial trauma in contact sports practitioners in the Federal District of Brazil

Abstract Aims: The purpose of this study is to assess the prevalence of oral and dentoalveolar trauma among contact sports practitioners in the Federal District of Brazil. Methods: A cross-sectional descriptive study was conducted using a questionnaire developed specifically for this research regarding the occurrence of facial trauma, site of injuries, how they occurred, the approach is taken to solve the problem, and the use of several types of mouthguards. Data were analyzed using the SPSS 20.0 software, and the chi-square test (X2) was chosen to examine the differences between categorical variables. The results were considered statistically significant for p<0.05. Results: A total of 141 athletes were interviewed, with a prevalence of facial trauma of 65.2%, which was higher in professional athletes (71.1%). Lesions ranged from soft tissue lacerations to combined trauma; and the most frequent injuries were soft tissue laceration (53.3%), combined trauma (16.3%), and dental fracture (9.8%). Only 20.6% of the participants required treatment for related injuries. Regarding the use of mouthguards, 34% of the athletes reported regular use of this device, and Type II mouthguard was the most used (39.7%). Dentists participate in the process of production and dissemination of mouthguards in 17.1% and 10.5% of cases, respectively. Conclusion: The data showed that most athletes are not aware of the importance of using mouthguards. The dentist must be more present in the area of sports dentistry, both for awareness and production of these devices, which support the safe practice of contact sports.

Introducción: El desgaste dental es un proceso insidioso y acumulativo que lleva a la destrucción del esmalte y la dentina; conocido como lesiones dentales no cariosas y son: Atrición, Abrasión, Abfracción y Erosión. En Cuba estas lesiones han sido poco estudiadas. Objetivo: Identificar las lesiones dentales no cariosas y sus formas clínicas en pacientes atendidos en la Clínica Estomatológica Siboney. Métodos: Se estudiaron 876 pacientes escogidos al azar de la población que fue atendida durante un período de 10 meses en dicha clínica estomatológica. A los mismos se les realizó un examen estomatológico para determinar si eran portadores o no de tales lesiones y cuál o cuáles variedades de las mismas presentaban. Resultados: Se comprobó que 102 de los 876 pacientes examinados eran portadores de lesiones dentales no cariosas para un 11,43 por ciento; de los cuales el 42,15 por ciento presentaron un solo tipo de lesión; 50 pacientes mostraron dos tipos de lesiones, para un 49,01 por ciento, en todas las combinaciones posibles, siendo la combinación más frecuente Atrición y Abfracción seguida por la Atrición y la Abrasión. Por último, nueve pacientes presentaron tres tipos de lesiones, para un 8,82 por ciento; en este caso la combinación más frecuente fue Atrición, Abfracción y Erosión. Conclusiones: El porcentaje de pacientes con lesiones dentales no cariosas fue relativamente elevado; pudiendo presentarse una lesión aislada o combinaciones de dos o tres; siendo las formas clínicas más frecuentes: Abfracción, en el caso de una lesión; Atrición y Abfracción en el de dos y Atrición, Abrasión y Erosión, en el de tres(AU)

Introduction: Dental wear is an insidious and cumulative process that leads to the destruction of enamel and dentin; Known as non-carious dental injuries and are: Attrition, Abrasion, Abrasion and Erosion. In Cuba these injuries have been little studied. Objective: To identify non-carious dental lesions and their clinical forms in patients treated at the Siboney Stomatology Clinic. Methods: We studied 876 patients chosen at random from the population that was attended during a period of 10 months in said stomatological clinic. They underwent a stomatological examination to determine if they were carriers or not of such injuries and which one or which varieties of them they presented. Results: It was verified that 102 of the 876 patients examined were carriers of non-carious dental lesions for 11.43 percent; of which 42.15 percent presented a single type of injury; 50 patients showed two types of injuries, for 49.01 percent, in all possible combinations, with the most frequent combination being Attrition and Abfraction followed by Attrition and Abrasion. Finally, nine patients presented three types of injuries, for 8.82 percent; in this case the most frequent combination was Attrition, Abrasion and Erosion. Conclusions: The percentage of patients with non-carious dental lesions was relatively high; being able to present an isolated lesion or combinations of two or three; the most frequent clinical forms being: Abfraction, in the case of an injury; Attrition and Abrasion in the two and Attrition, Abrasion and Erosion, in the three(AU)

Orofacial injuries in children and adolescents (2009-2013): a 5-year study in Porto, Portugal

Abstract The aim of this study was to verify the prevalence of acts of aggression to the head, face and neck towards victims of Physical Violence against Children and Adolescents (PVCA) who were examined at the National Institute of Legal Medicine and Forensic Sciences Delegation North (INMLCF-DN) in Porto, Portugal. A study was carried out on 2,148 complaints of physical aggression against children and adolescents (0 to less than 18 years old) occurred between 2009 and 2013 and which were retrieved from information about violence held on INMLCF-DN data files. Continuous variables were described and the association between them was verified by Chi-square or Fischer's Exact tests with 5% significance level. Within the 5-year timespan, 1,380 cases were identified with clinical relation with physical aggression. Most subjects evaluated were male adolescents and the most affected body region was the face, to which 747 injuries (24.7%) were recorded, with statistically significant association between sex and region (head and face). Victims in 15-17-year-old age group are more susceptible to violence than those in the 0-14-year-old age range. Dentists routinely examine the face, neck and skull, which make them the most appropriate health professionals to identify cases of aggression early.

Resumo O objetivo deste estudo foi verificar a prevalência de atos de agressão à cabeça, face e pescoço em relação às vítimas de Violência Física contra Crianças e Adolescentes (PVCA) que foram examinadas no Instituto Nacional de Medicina Legal e Delegação de Ciências Forenses Norte (INMLCF -DN) no Porto, Portugal. Um estudo foi realizado em 2.148 queixas de agressão física contra crianças e adolescentes [0 a menores de 18 anos] ocorridas entre 2009 e 2013 e que foram recuperadas de informações sobre violência mantidas em arquivos de dados do INMLCF-DN. Variáveis contínuas foram descritas para verificar a suas correlações foram usados os testes do Chi-Quadrado e o Teste Exato de Fisher em um nível de significância de 5%. Nestes 5 anos, foram detectados 1.380 casos que apresentam nexo clínico com agressão física. As vítimas mais acometidas eram adolescentes do sexo masculino, a região do corpo mais atingida foi a face com 747 das lesões (24,7%) registradas. Há significância estatística no teste do qui-quadrado de Pearson na relação de gênero com a cabeça e o rosto. Dentistas rotineiramente examinam o crânio, rosto e pescoço que os torna os profissionais mais adequados para identificar casos de agressão precoce. Os adolescentes são mais suscetíveis à violência do que as crianças menores de 12 anos.

What increases the risk of dental traumatism in patients with developmental disabilities?

Abstract This study investigated risk factors for tooth injuries in individuals from a dental clinical reference service for patients with special needs in Belo Horizonte, MG, Brazil. This is a retrospective cohort study that evaluated 493 dental charts of individuals with or without tooth injuries at their first dental appointment. The dependent variable was the time of occurrence of new dental traumatic injuries and was measured in months. Gender, age, International Code of Diseases, mother's education, mouth breathing, hyperkinesis, pacifier use, thumb sucking, psychotropic drug use, tooth injuries at the first dental examination, involuntary movements, open bite, having one or more siblings and reports of seizures were the covariates. The Cox proportional hazards regression model was used to estimate the unadjusted and adjusted hazard ratios and their respective 95% confidence intervals. The average time that individuals remained free of dental traumatism was 170.78 months (95% CI, 157.89-183.66) with median of 216 months. The incidence of new events was 11.88%. The covariate associated with an increased risk of dental traumatism was a history of tooth injuries at the first dental appointment. The increase in dental trauma risk was 3.59 (95% CI, 1.94-6.65). A history of traumatic dental injury was the risk factor for the dental trauma found in this group of individuals with developmental disabilities.

Este é um estudo de coorte retrospectivo que avaliou 493 prontuários de indivíduos com ou sem traumatismo dentário em sua primeira consulta odontológica. A variável dependente foi o tempo de ocorrência de novas lesões traumáticas e foi mensurada em meses. Sexo, idade, Código Internacional de Doenças, educação materna, respiração bucal, hipercinese, uso de chupeta, sucção digital, uso de medicação psicotrópica, lesões dentárias no primeiro exame odontológico, movimentação involuntária, mordida aberta, ter um ou mais irmãos e relatos de convulsões foram

Evaluation of cases of concussion and subluxation in the permanent dentition: a retrospective study

Abstract Objectives This study evaluated the evolution of cases of concussion and subluxation through a retrospective study of 20 years. Material and Methods Were examined clinical and radiographic records of 1,309 patients who underwent treatment of dentoalveolar trauma in the discipline of Integrated Clinic of the School of Dentistry of Araçatuba, UNESP, of which we selected 137 whose patients had concussion and subluxation injuries, with average age of 23.3 (SD - 10.96). The variables collected were: gender, age, history of previous and actual trauma, treatments performed, the presence of necrotic pulp, and time elapsed until the same trauma. The concussion and subluxation groups were subjected to statistical analyses using the SPSS 16.0 version software (α=0.05), Chi-square, and t-tests. Results Of the 301 teeth involved, 49 (16.3%) suffered concussion and 252 (83.7%), subluxation, being the upper anterior teeth the most affected (75.1%) for both conditions. Subluxation and concussion traumas were more prevalent in men aged 10 to 20 years, most caused by cycling accidents (36.2%). There was a concomitant presence of crown fracture in 21% of cases of concussion and 34.7% of subluxation. Pulp necrosis was detected in 16.3% (concussion) and 27.1% (subluxation) (p=0.12), and most occurred within 6 months after the trauma (p=0.29). The pulp necrosis shows a positive correlation with motorcycle accidents (p=0.01), direct impact (p≤0.0001), crown fracture with pulp exposure (p≤0.0001), darkening of the crown (p=0.004) and spontaneous pain (p≤0.0001); and negative correlation with indirect impact (p≤0.0001). Conclusions Although concussion and subluxation traumas are considered of minor degrees, they must be monitored, since the possibility of pulp necrosis exists, and its early treatment favors a good prognosis.

Prevalence and etiology of dental trauma in schoolchildren aged 6 to 12 years

Aim: To investigate the prevalence and etiological factors of dental trauma in school-age children aged 6 to 12 years. Methods: A study was developed in children and adolescents between the ages of 6 and 12 of both genders enrolled in 3 municipal public schools. An oral examination of the permanent or deciduous incisors was performed, if they were still present in the oral cavity, to evaluate the presence of dental trauma, need for treatment and sequels, and the method of examination and classification of dental trauma of O'Brien. Results: The prevalence of dental trauma was 4.03% (n=29). The most verified traumas were enamel crack / enamel fracture and enamel / dentin fracture without pulp exposure. It was observed that the most affected teeth were the permanent upper central incisors and the age at which trauma was most observed was 11 years, the main etiological factor was fall from a height, in 65.3% of schoolchildren (n=19). Conclusion: The prevalence of dental trauma was 4.03%, with no statistically significant difference between genders. The permanent right upper central incisor was the most affected, occurring predominantly at home and at school. The dissemination of information about dental trauma and emergency protocols to parents and teachers need to be encouraged

ABSTRACT: The aim of this study was to carry out a retrospective study of cases seen at the Child and Adult Dental Traumatology Clinic, Faculty of Dentistry, Universidad de Chile, Santiago. A retrospective study was carried out analysing the records of patients seen at the Dental Traumatology Clinic, Faculty of Dentistry, Universidad de Chile from January 2012 to March 2017. The inclusion criteria was that patient complaint was due to dental trauma. Data were tabulated indicating age and sex of the patient, cause, day, and tooth involved and the initial diagnosis of the dental trauma. Chi-square, Shapiro Wilk normality test and Mann-Whitney test were used for frequency analyses. A total of 117 dental records were analysed, 90 of these met the inclusion criteria. The age range of the sample was 5 to 60 years, and the average age was 14.3 years. Most injuries occurred in patients during the first and second decades of their life. Of the patients, 59.3 % were men and 40.7 % were women. The most frequent dental traumas were complicated and uncomplicated crown fractures, followed by root fractures. In the majority of the cases analysed, only one tooth was affected, and the tooth most frequently traumatized was the right upper central incisor, followed by the left upper central incisor. The most frequent dental trauma of the cases treated at the Child and Adult Dental Traumatology Clinic, Faculty of Dentistry, Universidad de Chile, Santiago, between 2012 and 2017 were crown fractures.
