Population studies on the prevalence of TMD (Temporomandibular Disorders) and their associations with quality of life (QoL), emotional states and sleep quality in Southeast Asian youths are not available. This cross-sectional study assessed the presence of TMD and their relationships to QoL, depression, anxiety, stress and sleep quality in a cohort of Southeast Asian adolescents / young adults. Three hundred and sixty two students from a polytechnic were enrolled in the study and completed an on-line questionnaire consisting of the Fonesca’s Anamnestic Index (FAI), Oral Health Impact Profile for TMD (OHIP-TMD), Depression, Anxiety and Stress Scales-21 (DASS-21) and Pittsburgh Sleep Quality Index (PSQI). The FAI appraises TMD severity while OHIP-TMD determines the effect of TMD on oral health related QoL. Statistical analysis was done using chi-square test for categorical data whilst one-way ANOVA / post-hoc Bonferroni tests were employed for numerical scores (p<.05). Of the 244 participants who completed the questionnaires in their entirety (37 males; 207 females, mean age 20.1±3.2 years), 32.4% had mild TMD, 9.4% had moderate TMD and 58.2% were TMD free. The total prevalence of TMD was 41.8% (n=102) and most OHIP-TMD domains including functional limitation (p=.000), physical pain (p=.000), handicapped (p=.000) and psychological discomfort (p=.001) showed significant differences in mean scores depending on TMD severity. A similar trend was observed for DASS-21. The majority of participants with TMD (69.6%; n=71) had poor sleep quality (p=.004). TMD appear to be prevalent in Southeast Asian youths with varying severity. Severity of TMD had some bearing on quality of life, emotional states as well as sleep quality.
