Frontal smile and Lateral profile photographs were digitally altered at full-face view and close-up view of adult men and women aged 15-30 years were used. The patient wase made to sit with a natural head position. Six incisal labial and lingual inclinations of the central incisors were simulated with changes of 5 degree. Alterations in the labially inclined direction were labeled as positive and those in the palatally inclined direction were labeled as negative. The positions were denominated as follows: 5 ͦ, 10 ͦ, 15 ͦ, ‐5 ͦ, ‐10 ͦ and –15 ͦ, according to incisal inclination changes of the central incisors. To simulate the different incisal inclinations adobe Photoshop CS 8.0 was used. The top limit of the full-face image was a region little above the top of the head and the bottom limit was the base of the neck. The images were randomly assembled in an album that were presented to 40 orthodontists, 40 general dentists and 40 laypersons who evaluated the attractiveness of the images by using Visual Analogue Scale. 10was found to be most attractive incisal inclination.
