Smile beauty is considered the main goal in many cosmetic or orthodontic dental treatments. However many objective and sujectives methods were developed to evaluate smile attractivesness depending on many variables. The purpose of this study was to develop a new method based on digital smile design teeth outlines ratios for smile esthetic evaluation and to correlate this method with Q-sort assessment method and smile mesh variables. Frontal posed smile photograph of 48 individuals were subjected to smile mesh measurments, digital smile design (DSD) and Q-sort assessment method. The areas of DSD teeth outlines were measured using image J software in addition to the teeth areas lie in the outlines to calculate the ratio of each individual tooth area to its outline area and the total teeth areas to totsl outlinrs area. The results showed a significant correlation between the new method and Q-sort asseseement method, additionally there was a significant difference in individual and total teeth outlines ratios between the pleasant and unpleasant smile groups. Conclusions It was found that Digital smile design teeth outline ratios method could be considered as a valuable tool for evaluation of smile esthetics.
