Frequência de reabsorção radicular inflamatória decorrente de trauma em dentes anteriores / Inflammatory root resorption frequency due to trauma in anterior teeth

Objetivo: a reabsorção radicular inflamatória é uma das consequências do traumatismo dentário, sendo a detecção e o tratamento precoces determinantes na limitação de seus danos. Assim, o objetivo deste estudo foi investigar, em dentes anteriores permanentes traumatizados, a prevalência de reabsorção radicular inflamatória, relacionando-a com os diferentes tipos de traumatismos nos tecidos de sustentação e dentários. Sujeitos e método: os dados relativos à reabsorção inflamatória foram coletados a partir de 111 dentes, nos prontuários de 74 pacientes de um serviço de tratamento de trauma dental da FO/UFPel, no período de 2005 a 2011. Foram registrados, ainda, o sexo e a idade dos pacientes, os dentes envolvidos no trauma, a presença de rizogênese completa ou não e o tempo inicial para o aparecimento da reabsorção. A avaliação dos dados foi realizada por estatística descritiva e teste qui-quadrado, com correção de Yates, ao nível de significância de 5%. Resultados: a reabsorção radicular inflamatória foi mais frequente em pacientes do sexo masculino, em incisivos superiores, em dentes com rizogênese completa e nas lesões de menor gravidade nos tecidos dentários e de sustentação. Ainda, as lesões nos tecidos de sustentação, quando não combinadas às fraturas dentárias, apresentaram maior frequência de reabsorção. O tempo inicial para o aparecimento da patologia foi dentro dos primeiros trinta dias após o trauma. Conclusão: é importante diagnosticar detalhadamente os traumas nos tecidos dentários, a fim de verificar o comprometimento dos tecidos de sustentação, devendo a proservação desses casos ser sistemática e contínua para interceptar a reabsorção radicular.

Objective: inflammatory root resorption is one of the consequences of dental trauma so its early detection and treatment are crucial in limiting their damage. Thus, this study aimed to investigate the prevalence of inflammatory root resorption in traumatized permanent anterior teeth, relating it to the different types of trauma in support and dental tissues. Subjects and method: data concerning inflammatory resorption were collected from 111 teeth, in medical records of 74 patients of a dental trauma care in UFPel’s Dentistry School, from 2005 to 2011. Gender and age of patients, teeth involved in the trauma, presence or absence of full rooting, and the initial time of root resorption emergence were also registered. Data assessment was performed by descriptive statistics and chi-square test with Yate’s correction, at significance level of 5%. Results: inflammatory root resorption was most frequent in male patients, in upper incisors, in teeth with complete root formation, and in minor injuries of dental and support tissues. Also, the supporting tissues injury presented higher resorption frequency when not combined with dental fractures. The starting time for pathology emergence was within the first thirty days after the trauma. Conclusion: it is important to thoroughly diagnose the trauma in dental tissues to verify the impairment of support tissues, since the proservation of these cases should be systematic and continuous to intercept root resorption.

Orofacial injuries in sports and use of mouthguards among university students

Aim: To evaluate the prevalence of orofacial injuries during practice of sports and the use of mouthguards by university students in the southern region of Brazil. Methods: In this cross sectionalstudy, 700 undergraduates from the University of West Santa Catarina, Brazil, filled out a questionnaire with multiple-choice questions addressing social and economic status, education level of parents, orofacial injuries from sport practice, knowledge, importance and use of mouthguards. The collected data were entered into the EpiData 3.2 program, and were analyzed by descriptive statistics and the chi-square test using STATA 8.0 statistical software package with a significance level set at 5%. Results: Out of the total number of students surveyed, 37.02%claimed to have already sustained some kind of orofacial injury. Out of these, only 9.90% sought dental assistance after trauma. The most common injuries were: bleeding 54.55%, swelling23.72%, and dental fractures 16.21%. Among the interviewees, 19.24% had already used mouth guard and 44.89% considered its use as important. Conclusions: The prevalence oforofacial injuries during sport activities was high in the studied sample and only few of the interviewed university students used individual protection measures to avoid these injuries.

Nivel de información sobre traumatismos dentoalveolares en padres y educadores / Information level about dentoalveolar traumatisms in parents and educators

Los traumatismos dentoalveolares (TD) son eventos que suceden frecuentemente. Las cifras son significativas en cuanto a la incidencia y prevalencia, se considera como un problema de Salud Pública Global. Objetivo: evaluar el nivel de información sobre traumatismos dentoalveolares en padres y educadores, en la escuela “Josué País García”’ de la ciudad de Camagüey. Método: se realizó un estudio transversal y descriptivo desde Septiembre de 2006 a Mayo de 2007. El universo se conformó por los padres y educadores de la escuela y la muestra quedó constituida por sesenta padres y veinte educadores, se evaluó un cuestionario de forma cuantitativa y cualitativa. Resultados: la conducta a seguir ante un traumatismo fue evaluada de insuficiente con 76,6% en los padres y los educadores con 85%. Las variables de años de experiencia de los educadores fueron evaluados de insuficientes con cifras de 50, 30, 20%. Conclusiones: la evaluación general de la información sobre traumatismos dentoalveolares fue de regular e insuficiente en la mayoría. Las necesidades sentidas y reales coincidieron y se centraron en los temas de: factores de riesgo, características clínicas y conducta a seguir.

The dentoalveolar traumatisms (DT) are events that frequently happen. The figures are significant as for the incidence and prevalence, it is considered as a Global Public Health problem (1). Objetive: To evaluate the information level about dentoalveolar traumatisms in parents and educators, in the school “Josué País García” of Camagüey city. Method: A cross-sectional and descriptive study from September 2006 to May 2007. The universe was conformed by parents and educators of this school and the sample was constituted by sixty parents and twenty educators, a questionnaire in a quantitative and qualitative way was evaluated. Results: The conduct to follow in the face of a traumatism was evaluated of insufficient with 76,6% in parents and 85% in educators. The variables of years of the educators' experience were evaluated of insufficient with figures of 50, 30, 20%. Conclusions: The general evaluation of the information about dentoalveolar traumatisms was regular and insufficient in the majority. The felt and real necessities coincided and they were centered in the topics of: risk factors, clinical characteristics and conduct to follow.
