Oral behaviors, bruxism, malocclusion and painful temporomandibular joint clicking: is there an association?

The present cross-sectional case-control study aimed to determine if there is an association between specific oral behaviors, sleep bruxism (SB), awake (AB), and painful temporomandibular joint (TMJ) clicking. Ninety individuals were dived into three groups; Group 1 (n = 30): TMJ clicking; 2 painless 3 control group. following clinical data studied: behaviors (unilateral chewing, gum nail biting, foreign objects leaning with jaw against the hand, sleeping in a position that pressures jaw), SB, AB (including frequency 10 days, evaluated by ecological momentary assessment), malocclusions investigated based on inspections (anterior open bite, posterior cross-bite, abnormal overbite/overjet, occlusal guidance, mediotrusive and/or laterotrusive interferences, retruded contact maximum intercuspation slide, missing teeth). All statistical tests (Kolmogorov-Smirnov, chi-square, one-way ANOVA) performed 5% significance level. had highest of significant jaw, (p<0.05). Gum associated only when compared No difference among groups was found for other chewing biting), all (p>0.05). It can be concluded patients clicking higher some harmful AB.
