Correlation of prosthetic status with the GOHAI and TMD indices.

This study sought to find a correlation between the prosthetic status and TMD and between the prosthetic status and self-perception of oral health in a Brazilian elderly population (n = 400). Prosthetic status was recorded in clinical examinations, and TMD was determined by applying the Helkimo index. Self-perception of oral health was evaluated based on the Geriatric Oral Health Assessment Index (GOHAI). The most prevalent prosthetic status was edentulous using complete dentures (47.5%). Absence of subjective TMD symptoms was found in 69.5%, and of clinical TMD signs in 38.3% of the population. The average GOHAI score was 33.02 +/- 2.85. A correlation was found between prosthetic status and TMD subjective symptoms (P = 0.017), but prosthetic status and TMD objective signs were uncorrelated (P = 0.061). Prosthetic status and self-perception of oral health were positively correlated (P = 0.001).
