Abstract :
Objective Interpupillary line has been used to guide the arrangement of upper anterior teeth in prosthodontics works. The occlusal plane of upper anterior teeth should be parallel to the interpupillary line. However, in reality, these two planes may not be parallel. This study was designed to investigate the relationship between the occlusal plane of upper anterior teeth and interpupillary line.
Materials and methods Sixteen male students and twenty-nine female students who never received orthodontic treatment were participated in this study. By using the digital camera, the photos of their eyes and plane of upper anterior teeth while biting balsar wood stick were taken. The photos were then transferred to computer and measured by computerized program. The data were analyzed by Paired Sample Statistics.
Result There is statistically significant difference between the angle of interpupillary line against horizontal plane and the plane of upper anterior teeth within the group of Thai dental students (P<0.05)
Conclusion The interpupillary line is not parallel to the plane of upper anterior teeth.
