Aim: Assessment of patient's motivations requesting orthodontic treatment can help clinicians in meeting the needs and expectations of patients and attain a successful treatment result.
Objective: The present study was carried out in 2008 to provide data regarding motives of patients coming to specialized orthodontic clinics of Qazvin for treatment.
Materials and Methods: In this descriptive study, 300 patients aged 12 years old and more (27.3% males, 72.7% females, the mean age: 19.61 years) were studied. Age, gender, parents’ level of education, and father’s occupation, motives for improving teeth and face components; and the location of pain and discomfort were evaluated. The correlation between motives and different socioeconomic factors were assessed using Spearman and Pearson correlation coefficients.
Results: Alignment of the anterior teeth was the most frequent motive regarding the teeth (89.3%). However, for face components ,it was improving teeth and gingival view during smiling (18.7%). Significant correlations were noted between patients' gender and motivation to align anterior teeth (p<0.009), movement of the lip (p<0.01), change of the nose length (p<0.002) and position (p<0.03) while females had higher motivation for these changes. As mothers’ level of education increased, the motivation to change the height of anterior teeth (p<0.03), improving the teeth and gingival appearance during smiling (p<0.001), decreasing the lip or chin tension in the closure of the lips (p<0.05) and decreasing the prominence or width of the mandible toward the mouth (p<0.01) decreased significantly. 
Conclusion: Alignment of anterior teeth and improving the teeth or gingival appearance during smiling were found to be major motives for requesting orthodontic treatments.
