Association of horizontal and vertical overlap with a prevalence of temporomandibular disorders

The aim of the study was to evaluate the relationship between horizontal (HO) and vertical overlap (VO) and prevalence of temporomandibular disorders (TMD) in a non-patient population. Out of the total number of subjects (230), 65, 7% subjects were classified as asymptomatic, 5, 7% subjects had muscle disorders (MD) (myalgia), 9, 1% subjects had disc displacement with reduction (DDR), while 19, 6% subjects had disc displacement with reduction associated with muscle disorder (DDR + MD) (myalgia). The HO equal to or greater than 5 mm was significantly more prevalent in the symptomatic patients (MD, DDR, DDR + MD) than in the asymptomatic group (P < 0, 001). The VO equal to or > 5 mm also demonstrated statistically significant difference (P < 0, 006) between the symptomatic (suffering from DDR, and DDR + MD) and asymptomatic subjects. Conclusion of the study is that the HO and VO equal to or > 5 mm was more present in the group of subjects with diagnosis of a TMD (DDR and MD), what distinguishes this group from the group of asymptomatic subjects.
