BACKGROUND: A unified framework for assessing temporomandibular disorder (TMD) pain and dysfunction across multiple symptom dimensions is beneficial.
OBJECTIVES: The study explored the associations between TMD symptom subtypes and dimensions with emotional distress, jaw function and oral health-related quality of life (OHRQoL). Additionally, it examined factors linked to high jaw functional limitation (JFL) and low OHRQoL.
METHODS: Participants, recruited from a major university, completed a survey that included demographics, the four-dimensional five TMD symptoms (5Ts-4D) screener, depression, anxiety and stress scales-21 (DASS-21), JFL scale-8 (JFLS-8) and oral health impact profile for TMDs (OHIP-TMD). Data were analysed using Chi-square and nonparametric tests, along with logistic regression (α = 0.05).
RESULTS: Among the 414 participants (mean age 22 years, 77.8% women), 23.4% reported no TMD symptoms (NT), while 15.7%, 22.2% and 38.6% experienced pain-related (PT), intra-articular (IT) and combined (CT) symptoms respectively. Notable differences in global TMD severity (CT>IT/PT>NT), global distress (CT>IT, NT), JFL (CT>PT, IT, NT) and global OHIP (CT>IT/PT/NT; IT>NT) scores were observed. Moderate correlations were found between global TMD severity and both JFL and global OHIP in the PT and CT groups (rs 0.41-0.64), and between global distress and these factors in the CT group (rs 0.59-0.61). High JFL was associated with symptom interference (OR 1.38) and anxiety (OR 1.20), while low OHRQoL was related to symptom duration (OR 1.26) and interference (OR 2.09).
CONCLUSIONS: Individuals with CT show elevated symptom severity, emotional distress, jaw function and OHRQoL impairments. Tailored interventions targeting TMD duration, interference and anxiety could improve outcomes.
