[Natural head position's reproducibility on photographs]

Abstract

Introduction: The purpose of this study is to evaluate the reproducibility of natural head position with time on profile photographs.

Materials and methods: Our sample is composed of 96 students (20-30 years old) at the department of dentistry of Saint Joseph University in Beirut. Two profile photographs were taken in natural head position about a week apart.

Results: No significant differences were found between T0 and T1 (E = 1.065°).

Discussion: Many studies confirmed this reproducibility with time. Natural head position can be adopted as an orientation for profile photographs in orthodontics.
