p-Value was obtained from χ2 test and the mean difference between groups was obtained by post hoc analysis with Boneferroni test. p-Value significance was set at <0.05.
wTMD–pTMD, when the proportion of the presence of variable was significantly different between wTMD and pTMD groups; wTMD–iTMD, when the proportion of the presence of variable was significantly different between wTMD and iTMD groups; pTMD–iTMD, when the proportion of the presence of variable was significantly different between pTMD and iTMD groups; n.s., when there was no significant difference between groups; TMJ, temporomandibular joint.
