Introduction: Esthetics has great importance in restorative dentistry. It is important to obtain standardized anthropometric data to increase both treatment and esthetic success. A harmonious facial appearance is the most important goal of successful treatment in the esthetic field. It is a steady fact that human faces contrast from each other based on gender, race and ethnicity.
Objectives: This study was aimed to analyze the macro-esthetics of the face and the micro-esthetics of the maxillary anterior teeth to establish the normative values of Egyptian adults and detect possible gender differences.
Materials and methods: The sample consisted of 126 Egyptian dental students (63 males and 63 females) aged (18-24) years. Each student was clinically examined, and then extra-oral and intra-oral photographs were taken. The facial and dental measurements obtained using 2D Adobe Photoshop® CS5 software. Descriptive statistics were applied to the measured parameters and independent samples t-test was performed to assess gender differences.
Results: The results showed that for the linear and vertical facial variables (macro-esthetic appearance) the males have larger facial dimensions than females with highly significant gender differences. While for most of the maxillary anterior teeth proportions (micro-aesthetic appearance), the females have larger proportions than males with statistically significant gender differences.
Conclusion: Based on 2D digital photogrammetry, the macro-esthetic appearance, maxillary anterior teeth measurements and, the micro-esthetic appearance of Egyptian adults were analyzed and data were obtained. In most of the parameters, there was a statistically significant gender difference (P≤0.05).
