Results: 31 out of the 40 subjects taken in the study exhibited bruxism .Nail biting  habit was found to be present more in first and second time prisoners and almost absent in three or more timers with a significant value (p=0.009). Results showed a level of significance (p=0.008) indicating more bruxism in crime against person as compared to crime against property. Also, bruxism was significantly correlated to the emotional state of anger (p = 0.006).
