Brief summary: The goal of this cross-sectional study is to state the inter relation between anthropometric parameters of pristine maxillary anterior teeth and facial index and their correlation with recurring esthetic dental proportion (RED) using 3D digital software (Medit) with intra intraoral scanner.The study comprised of 20 adult out patients with an equal number of males and females who had 20-35 years old.

Detailed description: The research focuses on analyzing the proportions of maxillary anterior teeth in relation to facial measurements, particularly within the Egyptian population. It evaluates how closely these dimensions align with the Recurring Esthetic Dental (RED) proportions, which suggest that the width of anterior teeth should decrease by a constant ratio moving distally. Using advanced digital tools such as the BELLUS 3D face scanner and MEDIT i700 intraoral scanner, the study collected detailed facial and dental measurements from participants to explore the correlation between facial index and tooth dimensions. The sample consisted of 20 participants (10 males and 10 females), with data analyzed using statistical methods to assess symmetry and gender variations in these proportions.). Moreover the results were statistically analyzed using the Independent t-test or an equivalent non-parametric test was used for comparison between the two groups, and the Pearson's correlation coefficient (r) test was used for correlating different parameters.
