MARTINS, Ronald Jefferson; GARCIA, Alício Rosalino; GARBIN, Cléa Adas Saliba  and  SUNDEFELD, Maria Lúcia Marçal Mazza. The relation between socio-economic class and demographic factors in the occurrence of temporomandibular joint dysfunction. Ciênc. saúde coletiva [online]. 2008, vol.13, suppl.2, pp. 2089-2096.

Different factors like stress and occlusion can decrease the adaptive capacity of the stomatognathic system and lead to the occurrence of temporomandibular dysfunction (TMD). The objective of this study was to verify the relation of the variables socio-economic level, schooling, sex and age with the occurrence of temporomandibular dysfunction. The population of this study consisted of a statistically significant sample of subjects of both sexes belonging to different socio-economic classes living in the urban area of the city of Piacatu, São Paulo, Brazil. The Criterion of Economic Classification Brazil (CCEB) was used for the economic stratification of the population. Fonseca's Questionnaire was applied to samples collected from each extract to verify the level of TMD. The data collected were statistically analyzed using the Chi-square Test, with a significance level of 5%. In total, 354 heads of families participated in the research. No statistically significant relation was found between socio-economic class, schooling, age group and temporomandibular dysfunction (TMD). There was a relation between sex and TMD (p<0,02). The variables socio-economic class, schooling and age group had no influence upon the occurrence of TMD, however there is a significant relation with the sex of the individual.
