Coincidence Between Bipupillar Midline Bisector and Incisor Medial Face

Objective: Symmetry is one of the factors that contribute to facial harmony and in oral rehabilitation it determines the success of aesthetic treatment. The aim of this study was to analyze the axial symmetry between the bipupillar midline and maxillary central incisors of 102 dentistry students (both genders) distributed throughout five Brazilian dental schools.

Methods: Students were leucoderm without dental loss and had never been submitted to orthodontic/orthopedic treatment. Photographs were taken with a Dental Eye III camera with macro objective 100 mm and ratio of 1: 10 of natural size, recorded on Ektachrome ASA/ISO 100 film. The images were developed and applied to Microsoft Office Power Point 2007 software. The results were analyzed by ANOVA and Student's-t test (á = 5).

Results: There was no significant correlation between bipupillar midline and maxillary central incisors of the pupil secant and incisal edge of maxillary central incisors, irrespective of gender.

Conclusions: The interpupillar distance and its relationship with other anatomic structures can be use as a reference in treatments, but measurements must be assessed individually.
