The aim of this study was to find out the least acceptable malocclusion trait among crowding, spacing with overjet, open bite and deep bite. Materials and methods:The one hundred and nine college students were shown frontal photographs of four patients having severe crowding, spacing with increased overjet, open bite and deep bite. They were asked to rate their perception on visual analog scale. The data obtained was analyzed by SPSS.Results: In this study it was found that crowding of teeth was the least acceptable malocclusion trait followed by spacing and increased overjet, open bite and deep bite. Conclusion:Crowding malocclusion and spacing with increased overjet created the worst impression and were among the most disliked malocclusion traits. People having these malocclusion traits are easily noticed for their compromised esthetics and have to face discrimination.
