Introduction: Psychology and personality traits have proven impacts on patients` satisfaction with dento-facial aesthetics and appearance. Neuroticism {N} and Extroversion {E} are the most psychological traits that affect satisfaction with dento-facial appearance. Some tooth wear patients were found to be satisfied with their dental appearance despite severe effects of wear on dental appearance, others were found to be dissatisfied despite minimal effects of wear on dental appearance.

Objectives: Identification of the relation between psychological traits and satisfaction with dental appearance in tooth wear patients.

Methods: 50 patients were recruited into this study. Dental Impact on Daily Living and NEO PI-R questionnaires were used to assess Patient perception of dental aesthetics and personality traits respectively. 50 subjects who have no dental problems and matching the main tooth wear group by age, sex and level of education were used as a control group. Same tests were used with the control group.

Results: we found that all tooth wear patients who scored low in E were dissatisfied with dental appearance {p=0.0} and that all those who scored high N (except 1 patient) were also dissatisfied {p<0.05}. Control group subjects had no significant relation between psychological traits and perception of dental aesthetics.

Conclusion: We concluded that in tooth wear patients, low E scores and high N scores are associated with negative perceptions of dento-facial aesthetics and dissatisfaction with dental appearance.
