This study was undertaken to identify whether personality traits had any relationship with patients' satisfaction with their dentition in tooth wear cases. One hundred tooth wear patients and one hundred controls were recruited into the study. A Dental Impact on Daily Living questionnaire was used to assess impact of tooth wear on day to day life and satisfaction with the dentition. An ordinal scale was used to assess tooth wear severity in tooth wear patients. The NEO Five Factor inventory was used to assess personal profiles. Tooth wear patients were less satisfied with their dentition, had higher Neuroticism, lower Extraversion, and higher Openness than the controls.
