Purpose: The purpose of this study was to assess the association of vocational interest and personality with temporomandibular disorders (TMD). Methods: Four hundred and fourteen college students in Gyeonggi-do completed Vocational Preference Inventory L form and a questionnaire and collected data were analyzed by R program. Results: The percentage of subjects who responded that they had at least one contributing factor for TMD was significantly different among 27 two-letter Holland codes (p<0.05). The two-letter Holland codes of which the first-letter was social (S) (S artistic [A], S investigative [I], S realistic [R], S conventional [C], S enterprising [E]) or C (CE, CS, CA, CI) had tendency of having the relatively higher prevalence of symptoms and contributing factors for TMD. Among 6 one-letter Holland codes, the prevalence of a symptom of frequent fatigue in the jaw and a habit of gum chewing showed the significant difference (p<0.05). E code seemed to have lower prevalence of a symptom of frequent fatigue in the jaw than other codes. S code appeared to use chewing gum more frequently than other codes. High scorers on emotional instability showed the significantly higher prevalence of TMD symptoms (p<0.05) and contributing factors for TMD (p<0.001) than low scorers. Furthermore, high scorers on emotional instability had significantly higher mean scales of the number of positive answers of TMD symptoms (p<0.01) and of contributing factors for TMD (p<0.001) than low scorers. Conclusions: Symptoms and contributing factors for TMD were related to emotional instability. Vocational Preference Inventory L form might be utilized in assessing emotional factors of persons with TMD symptoms.
