METHODOLOGY It was a cross sectional, analytical study conducted in Art, Business and Dental Schools. Ninety 90 students (3 groups of 30 each)were selected by non probability, purposive sampling. 24 pictureswere run in front of the participants as power point presentations. The pictures were of two individual smiles, a male and a female, with changes made to colour of teeth and skin, inAdobe Photoshop. The participants were asked to grade each picture on a rating scale. SPSS 17.0 was used for data analysis. Frequency distribution of all variables was determined. Association of smile attractiveness with gender and profession was determined using Chi-square test. Mean ranks and score (of the 24 pictures) of smile attractiveness as perceived by the 3 groupswere compared using Kruskall-Wallis test.Level of significancewas set at 0.05 Results The sample size consisted of 34.1%males and 64.8%females. For the dental group smile attractiveness was very important as opposed to the business and art students. For females, smile attractiveness was more important than theirmale counterparts. Fair skinwith bright andmoderately bright teeth rated as themost attractive smile,whereas fair skinwith dark teeth rated as the least attractive smile.
