Abstract

Background: Evaluating the anteroposterior position of the maxillary incisors is an important step in the diagnosis and treatment planning in order to get better facial and dental esthetics. This study aimed to evaluate and compare the anteroposterior position of the maxillary central incisors in both genders and to find out whether there is a relation between this position relative to the forehead inclination.

Samples and methods: Eighty dental students (40 males and 40 females) having normal dental and skeletal relationships and pleasing profile agreed to participate in this study. Standardized profile photograph on smiling was taken for each student and analyzed by AutoCAD program to assess the anteroposterior position of the maxillary central incisors and the inclination of forehead. Independent sample t-test and Pearson's Chi-square were used to assess the gender difference, while Pearson's correlation coefficient was used to assess the relationship.

Results: Males showed maxillary central incisors positioned significantly more anteriorly relative to the forehead in comparison with females. In most of the studied sample, the maxillary central incisors were located anterior to the point glabella. Moderate to strong, direct, high significant correlations were found between maxillary central incisors position and forehead inclination in both genders.

Conclusions: The forehead is considered as a helpful landmark for assessing the facial profile as it correlated significantly with the anteroposterior position of the maxillary central incisors.
