MACHADO, Ilza Maria et al. Association between voice disorder and self-reported temporomandibular dysfunction symptoms in teachers. Audiol., Commun. Res. [online]. 2014, vol.19, n.1, pp.75-80. ISSN 2317-6431.


: To verify the relationship between voice disorder and temporomandibular dysfunction (TMD) in elementary and middle school teachers.


: The participants of this study were 138 teachers - 96 women and 42 men, with a mean age of 38 years. The teachers responded to a questionnaire with five questions on voice disorder and temporomandibular dysfunction symptoms. The data were analyzed using an association test (Chi-square) to verify the association between voice disorder and temporomandibular dysfunction symptoms, as well as the relationship of the symptoms with sex and age.


: The temporomandibular dysfunction symptoms reported by the teachers, from the most to least frequently mentioned, were as follows: headache or facial pain, pain at the end of the day, and pain when speaking excessively. The results showed a statistically significant difference for the symptom pain when speaking excessively, pain at the end of the day, and temporomandibular joint snap in teachers without voice disorder. A statistically significant difference was observed for the female sex, regarding temporomandibular dysfunction. Temporomandibular dysfunction was more frequently reported than voice disorder, with higher incidence in female than in male teachers.


: The findings showed a statistical association between voice disorder and temporomandibular dysfunction in teachers. Further studies with integrated clinical assessment on the relationship between voice symptoms and TMD in different age groups are warranted.
