A study was conducted to evaluate the changes in the attractiveness and acceptance of a posed smile with computerised variations of the smile parameters and head types. Two adults, one male and one female were selected. Their posed smile photographs were taken, which were morphed into different images [by using Adobe Photoshop Version 7 and Adobe Photoshop CS2 soft wares] . The judges in our study were educated and uneducated males and females and dental professionals. Results of our study showed that, the smile parameter acceptable for a particular head type was more or less acceptable to the other head types. The overall acceptance of smile parameters showed that an acceptable smile should have minimum buccal corridor space, an upper lip that elevates till the marginal gingiva and a lower lip that is coincident with the upper incisaledges. https://biomedpharmajournal.org/vol7no2/an-evaluation-of-the-attractiveness-of-a-posed-smile-with-computerised-variations-of-the-smile-parameters/ Acceptable smile parameters buccal corridor space posedsmile Smile arc
