[Investigation of relation between anxiety and TMJ dysfunction in dental students]

In this study relation between Temporomandibular Joint Dysfunction (TMJD) and anxiety was investigated. For this purpose 2 different questionnaires were given to a total of 360 students (192 girls and 160 boys) aiming to determine the anxiety levels and their tendency to develop TMJD. After obtaining the results from the questionnaire for TMJD, the students are first divided into 2 main groups according to have TMJD or not, then into 5 consisting of "bruxism", "occlusion", "trauma", "combined" and "normal" groups. The groups were compared with each other for the relation between anxiety, TMJD and age. A positive relationship was demonstrated between anxiety and TMJD but statistically significant correlation wasn't found between age and TMJD. Also, the results didn't show any correlation between bruxism and anxiety levels.
