Aim: A successful orthodontic treatment depends on a variety of Factors such as patient cooperation. Prediction of patient cooperation could be helpful for anticipating problems that might arise during treatment and alleviating them before they can interfere with treatment. Thus the aim of present study was to determine the relationship between psychological factors and cooperation of orthodontic patients.Methods and Materials: In this cross-sectional study, 48 Class I female fixed orthodontic patients (13-17 years old) were selected. For all patients Eyesenck questionnaires were completed and personality status of each patient for extroversion, neuroticism, psychoyicism and lie was determined. Patients' cooperation was also assessed through evaluating patients' folders in the first year after treatment using Orthodontic Patient Cooperation Scale. Finally, Spearman correlation test and t- test were used for statistical analysis.Results: The results of present study revealed that there exists a negative relationship between Extraversion (E), Neurosis (N) and Psychosis(P) traits of the Juvenile Eyesenck Personality Test(See Appendix) with patients' cooperation in the girls and a positive relationship between Lying trait(L) of the test and the cooperation. However, the results of Spearman correlation test showed there were no significant differences between patients' cooperation and PEN and L trails of the Juvenile Eyesenck Personality Test (p-value> 0.05).Conclusion: Orthodontic patients' psychological features could not predict their cooperation exactly.

The purpose of the present study was to assess lip line in deep bite patients in comparison to the normal situation.Materials and methods: Twenty young (18-24 years) females with anterior deep bite (vertical overlap of upper teeth was more than one third of lower teeth height) participated in this study. Two Standard photographs in frontal view were taken in rest position and posed smile. Incisor show was measured in these two gestures in photoshop program. Descriptive statistical methods were used to analyze data.Results: The average incisor show in our deep bite patients was 76.5% of central tooth crown total height. In 35% of our patients less than 70% of the incisor height was exposed during posed smile, and in 75% of the cases incisor teeth were not seen in rest position.Conclusion: Incisor show was less than minimum level of smile attractiveness in 35% of deep bite patients and the incisors were not seen at rest in 75% of these patients.
