Assessment of Orofacial Esthetics among Different Specialists in Dental Medicine: A pilot study

Little is known whether specialists in different dental fields assess orofacial esthetics differently due to various focus of their interest. The aim was to find out if there is a difference in judgement of orofacial esthetics among specialists in three different fields of Dental Medicine, i.e. specialists in Prosthodontics (S-Prosthod), Periodontology (S-Perio), and Orthodontics (S-Ortho).

A total of 69 specialists (23 participants in each group) assessed the same 60 photographs of the lower third of the face of young healthy people with Angle Class I and natural teeth while smiling. Moreover, the assessed anterior teeth on the photographs of similes had to be without any restorations. The assessments were made using 7 out of 8 Items of Orofacial Esthetic Scale (OES). A face profile assessment was not performed. A Likert 1-5 scale was used for assessments (1-the worst score; 5-the best score). Mean values of summary scores as well as of each OES item were calculated for each specialist for further statistical analysis. One-sample Kolmogorov-Smirnov test, descriptive statistics, one-way ANOVA, and Sheffe post-hoc tests were performed.

The specialists in Periodontology gave significantly lowest scores to all 7 items related to orofacial esthetics, while the specialists in Prosthodontics gave the highest scores (p<0.05).

Assessments of orofacial esthetics differ significantly among specialists in Prosthodontics, Periodontology and Orthodontics. Further study is needed to clarify the factors which influence the judgement, and to find out if specific education in certain specialties can modify the assessment.
