Abstract
ABSTRACT Objective Investigate the prevalence of dental traumas in participants of two contact sports (Judo and Taekwondo) and characterise some related factors. Methods Cross-sectional pilot study of observational nature, conducted by observing and collecting data and information. The sample consisted of 60 individuals of both genders aged between 5 and 15 years old, participants of Judo or Taekwondo. The statistical analysis involved descriptive and inferential statistical measures. Results The prevalence of dental trauma in the studied sample was of 38,3%, with the majority occurring outside the practice of sport (82,6%). Only 4 children suffered trauma whilst playing their sport, corresponding to a prevalence of 6,67%. In addition, all 4 cases pertained to the practice of Judo. The most affected teeth were the primary maxillary central incisors followed by the permanent maxillary central incisors, with only one injured tooth in most cases. The lips were the soft tissue with greatest number of registered traumatic lesions. A statistically significant relationship was observed between risk factors and the occurrence of trauma. Conclusion A high prevalence of dental trauma in the studied population was found. Despite no record of traumatic lesions in Taekwondo, this prevalence was particularly noticeable in Judo.
Highlights
The proper maintenance of removable dental prostheses is required for users of complete denture base in order to have a pleasant aesthetics, dentures free from odors and good oral health[1].The increase in health expectancy of people was followed by an increased interest in dental treatment on the part of elderly patients who were concerned with aesthetics and with oral health[2,3]
Objetivo Avaliar a microdureza de corpos de prova das resinas acrílicas VipiCril® e Bosworth New Truliner®, antes e após, a imersão em soluções de digluconato de clorexidine a 0,12 %, hipoclorito de sódio a 1%, Corega Tabs® e água, testando a hipótese nula de que os enxaguatórios bucais e substâncias químicas utilizadas na desinfecção de próteses totais não interferem na microdureza superficial, podendo assim, serem utilizados como coadjuvantes na higiene bucal de pacientes desdentados
Métodos Foram confeccionados 60 corpos de prova da resina VipiCril® e 60 corpos de prova da resina Bosworth New Truliner® com 16mm de diâmetro por 6mm de altura, estes foram divididos randomicamente em quatro grupos de 15 amostras cada, sendo submetidos a testes de microdureza Knoop (KHN), antes e após, ciclos de imersões em soluções de digluconato de clorexidine a 0,12%, hipoclorito de sódio a 1%, Corega Tabs® e água
Summary
The proper maintenance of removable dental prostheses is required for users of complete denture base in order to have a pleasant aesthetics, dentures free from odors and good oral health[1].The increase in health expectancy of people was followed by an increased interest in dental treatment on the part of elderly patients who were concerned with aesthetics and with oral health[2,3]. Many elderly subjects are affected by diseases that limit their manual ability[3,4], requiring complementation of the mechanical cleaning with chemical substances in order to avoid the accumulation of dental microbial plaque on the oral mucosa membrane and on the surfaces of dentures, what may lead to the development of several diseases, such as candidiasis[5,6]. The chemical disinfection methods available for partial and complete denture bases may cause alteration of physical and mechanical properties of the materials used in the composition of such denture bases. Clinical characteristics such as rugosity, hardness, dimensional stability of color and bending properties can be changed after immersion in those solutions[1,11,13]
