INTRODUCTION:Esthetics has great importance in restorative dentistry. It is essential to obtain standardized anthropometric data to increase both treatment and esthetic success. A harmonious facial appearance is the most essential aim 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 determine the normative values of Egyptian adults and investigate possible gender differences. MATERIALS AND METHODS:The sample size was 126 Egyptian dental students (63 males and 63 females) aged between (18-24) years. All students were clinically examined, and then extra-oral and intra-oral photographs were taken. The measurements of faces and teeth were obtained using 2D Adobe Photoshop® CS5 software. Descriptive statistics were applied to the measured parameters and independent samples ttest was used to assess gender differences. RESULTS: The results showed that for the linear and vertical facial measurements (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. CONCLUSIONS: Based on 2D digital photogrammetry, the macro-and micro-esthetic appearances of Egyptian dental students were analyzed, and data were obtained. In most of the parameters, there were statistically significant gender differences (P≤0.05).
