Preclinical and Clinical Students’ Perception of Smile Line and Buccal Corridor on Smile Esthetics Selen Elif Uz1, Zeliha Şanıvar Abbasgholizadeh1, Buket Evren1 1 Marmara University Faculty of Dentistry Department of Prosthodontics Objective: Physical appearance plays an important role in human behavior and social interaction in most cultures and among different age groups. Since the center of communication on the face is the mouth area, the attractiveness of the face and smile are closely linked to each other. The aim of this study is to assess if students’ perception of smile line and buccal corridor on smile esthetics are associated with their stage of studies (precilinical or clinical). Material and Methods: A frontal smile photo of a model was taken who presented with a Class I incisor relationship, aligned teeth, healthy periodontal tissues and no anterior restorations or staining. For the purposes of the study, this smile was identified as “ideal”. A set of 8 digital images were created; one image was the ideal smile and the remaining seven were modified using Adobe Photoshop to alter one feature of the smile in terms of buccal corridor and smile line. Flat, parallel and reverse smile lines were created and alterations made on buccal corridor width from 1 mm to 4mm. Dental students in year 1 and 2 (preclinical) and year 4 and 5 (clinical) were asked to complete the questionnaire according to their esthetic preferences. Results: A total of 500 questionnaires were completed. The analysis showed the perception of dental students changes across preclinical and clinical grades for both smile line and buccal corridor on smile esthetics. Clinical students prone to rank the ‘ideal smile’ as more pleasing and identify it as the “best” in terms of smile esthetics from the pair of images. Conclusion: The findings corroborate the results of previous studies regarding the effect of dental education on the smile esthetic perception of students. Keywords: Smile esthetics, Esthetic Perception, Buccal Corridor, Smile Line
