Abstract

Creating a database of anatomical features  of the anterior maxillary region including gum tissue, bone tissue, sagittal root position... for each ethnicity, gender, and age group is crucial. Objectives: To analyze and compare the characteristics of the buccal bone and soft tissue in the anterior maxilla between males and females, as well as among different age groups in Vietnamesme people, based on CBCT images. Materials and ethods: The study analyzed 100 CBCT images that met the selection criteria. Measured parameters included buccal bone thickness at various distances from the alveolar crest, gum thickness, the distance from the cemento-enamel junction to the alveolar crest, and the classification of root position. The values were compared between genders and among three age groups. Results: When comparing males and females, most indices in the central incisors of males were statistically higher than those of females. Regarding age, the buccal bone thickness at point C and the buccal soft tissue thickness in the central incisors decreased with age, CEJ-AC increased with age, and GM-AC in the lateral incisors decreased with age. Conclusion: In general, the thickness of the buccal bone and soft tissue in the anterior teeth was higher in males than in females and decreased with age.
