Abstract

Beauty with health is the motto of today’s world. This has made the focus of Dentistry nowadays, not only on preventing and curing diseases, but rather on meeting the demands for better esthetics
The Aim of this cross-sectional study was to establish reference data for facial dimensions of and the R/C ratios for the maxillary anterior dentition with complete root formation in the Egyptian population by using CBCT.
Subjects and methods: 600 CBCT scans 300 males and 300 females were collected between (2020–2024) from the archive of the radiology department in faculty of dentistry, The British University in Egypt and examined with two Oral Radiology specialists .
Results: The average root length of maxillary central incisors was 14.2 mm in males and 14 mm in females, while the lateral incisors measured 12.2 mm in males and 12.1 mm in females. For maxillary canines, the root length was 13.2 mm in males and 14 mm in females. The mean R/C ratios for maxillary anterior teeth ranged from 1.4 to 1.9 in both males and females
Conclusions: Males not only have broader anterior dentition but also slightly taller crowns than females. Interestingly, the maxillary central incisors exhibited the highest AI dimension in men, whereas the maxillary canines were the longest in women.
