Hajer Ibraheem, Ola Ali Khalaf


The aim of the study was to assess the prevalence of temporomandibular disorders (TMD) and oral parafunctions, as well as their correlation with psychoemotional factors among dental students by using diagnostic criteria (DC/RDC).the sample’s size of 407 students (169 males and 238 females) of dental college (100 fifth stage , 102 fourth stage ,99 third stage and 106 second stage ) . Firstly students subjected for stress questionnaire (perceived stress scale -10) , secondly they subjected to different clinical and questionnaire measures according to diagnostic criteria of temporomandibular disorders DC/TMD (axis1) which have standerized series of diagnostic tests based on clinical signs and symptoms , finally the dental students subjected for oral parafunctions ques- tionnaire using oral behavior checklist.the results obtained from this study showed that the prevalence of TMDs was significantly greater among students with oral parafunctions . We also observed that the prevalence of TMDs according to DC/TMD was higher among students with headache .in this study, the prevalence of psycho-emotional stress , TMD according to DC/TMD and oral parafunctions were higher in females than males and in fifth stage greater than other stages.the prevalence of TMDs according to DC/TMD were significantly higher among females than males.
