The study aims to find out the preferable maxillary incisor inclination in the smile profile of a female subject with respect to altered mandibular positions and to elucidate whether the rater’s profession plays a role in assessment of optimally esthetic facial profiles. Methods: A smiling profile photograph of a female patient with average facial profile was altered artistically to obtain 3 different mandibular positions in decrements, normal and increments of 4 mm and in each positions the incisors inclinations have been altered to different positive and negative inclinations. A total of 37 evaluators including panel of Professionals and Non-professionals were asked to score each photograph using a Likert-type scale. Mann-Whitney and Kruskal–Wallis tests is done for statistical analysis. Results: In retruded mandible normal incisor inclination is favoured by the Professionals and +5˚ incisor inclination by the Non-professionals. In orthognathic mandible +5˚ of incisor inclination is favoured by Professionals and +10˚ by Non-professionals and in protruded mandible normal incisor inclination is favoured by Professionals and +10˚ by Non-professionals. Conclusions: There is a youthful quality of establishing a slight protrusive maxillary denture for a woman in cases of mandibular deficiency or excess.
