Abstract

Objective: Determination of mesiodistal and crown height dimensions of teeth in both arches among Muong adults aged 18–25 in Nho Quan District, Ninh Binh Province in 2025. Subject and methods: A cross-sectional descriptive study of 158 Muong individuals (76 males, 82 females) using 3D scan models and the automatic measurement tool of the 3Shape software. Results: The dimensions of permanent teeth in both arches were determined, with no significant differences between the right and left sides. All measured dimensions including mesiodistal width and crown height of the incisors, canines, premolars, and first permanent molars were greater in males than in females. These differences were statistically significant (p<0,05). Conclusions: The mesiodistal width and crown height of the incisors, canines, premolars, and first molars in both arches among the Muong population showed bilateral symmetry and were larger in males than in females. These measurements were comparable to those of the Kinh population. However, permanent tooth dimensions differed among various ethnic groups across broad geographical regions.
