Introdução:
A prática de instrumentos de sopro pode provocar forças excessi vas que
influenci am a dentição. Os instrumentos de sopro podem ser divididos em quatro classes,
de acordo com o tipo de embocadura. Assim, consoante a posição adoptada para a prática,
diferentes forç as ser ão exercidas e diferentes más oclusões dentárias poderão ocorrer.
O
bjetivo: Avalia r se as diferentes classes de sopro influenciam o mau posicionamento
dentário e o desenvolvimento da má oclus ã o.
Métodos
e Materiais: Foi realizado um estudo transversal, descritivo e observacional,
comparando parâmetros o clusais de 40 alun os de sopro. Os participantes foram agrupados
em quatro grupos consoante o tipo de instrumento que praticavam. Foram realizadas
impressões em alginat o, fotografias intra e extraorais. Os parâmetros oclusais foram
avaliados nos modelos de estudo. Os dados f oram analisados estatisticamente com recurso
ao SPSS ® Em todos os testes foi considerado um valor de p 0,05 como estatisticamente
significativo.
Resultados:
Dos ind ivíduos observados, 22 pertenciam ao género feminino e 18 ao género
masculino, apresenta ndo uma média de idades de 13,6 2,3 anos. O estudo incluiu 16
alunos de classe A, 11 de classe B, 4 de classe C e 9 de classe D. Verificou se uma relação
estatisticamente significativa entre as diferentes classes de sopro e a classe molar I direita
p 0,016) bem como com a classe molar II incompleta direita p 0,036) No que diz
respeito a o overject overbite classe canina, mo rdidas cruzadas e mordida aberta, es tes
não apresenta m significância estatística entre as diferentes classes.
Conclusões:
A prática de instrumentos de sopro não aparenta influencia r o overject
overbite mordida cruzada e mordida aberta. Relativamente à classe molar, observou se
uma maior prevalência de classe molar I direita nas classes de sopro B e D, e uma maior
prevalência de classe molar II incompleta direita nos instrumentistas de classe C.
Introduction: Playing wind instruments can cause excessive forces that influence the dentition Wind instrume nts can be divided in four groups according to the mouthpiece. Depending on the position adopted for the instrument, different forces can be exerted, and different malocclusions can occur. Objective: E valuate if the different groups of wind instruments ha ve influence on teeth position and if influences the development of malocclusions. Methods and Materials: This is a cross sectional, descriptive and observational study, comparing the occlusion of 40 wind instruments students The players w ere divided in four groups according to the type of instruments they played. Impressions, intraoral and extraoral photographs were taken. The occlusal parameters were assessed on the study casts. The data was treated statistically using SPSS ® In all the statistical anal yses a p value of 0. 05 was considered as statistically significant. Results: From the observed individuals, 22 were female and 18 were male, presenting a mean age of 13.6 2.3 years. The study included 16 class A students, 11 class B students, 4 class C students and 9 class D students. This study showed a statistically significant relation between the different classes of wind instruments and the right molar class I p 0. 016) as well as the right molar class II i p 0. 036) However, the overject, o verbite, canine class, crossbites and open bites did not present significant statistical evidence. Conclusions: The practice of wind instruments does not seem to influence the overject, overbite, cross bite s and open bite. However, there i s a higher preva lence of right class molar I among the players of class B and D, and a higher pr evalence of right class molar II i in players from class C.
