In cases of dysphonia, the voice is unable to play its basic role of transmission of verbal and emotional messages of an individual. Conversely, temporomandibular dysfunctions (TMDs) are originated from abnormal functioning of the masticatory muscles, temporomandibular joint (TMJ), associated structures or both. Considering that several studies have been conducted to understand the relationship between the emotional condition and situations of dysphonia and TMD, yet the studies seldom address individuals who present both conditions, this study aimed to verify if women with dysphonia present greater rates of TMD than women without dysphonia, as well as to check the influence of these disorders on the quality of life, and correlate the severity of TMD and dysphonia. The study will be conducted on sixty women aged 20 to 40 years, who will be divided into 2 groups with 30 subjects each. Group I will comprise patients of the Speech Therapy Clinic of Bauru Dental School presenting dysphonia, and Group II will include women without dysphonia living at the city of Bauru. All selected women will be submitted to evaluation of quality of life related to dental and speech therapy aspects, by application of the questionnaires Oral Health Impact Profile-14 (OHIP-14) and Quality of Life in Voice (QVV). The anamnestic questionnaire directed to classification of the severity of TMD will also be applied. A speech therapy evaluation related to the vocal quality will be applied by using the GRBAS scale, as well as dental assessment addressing the oral health condition.The results achieved will be recorded on Excel worksheets for later statistical analysis.
