Abstract

Objective: To evaluate the current status of occlusion and its characteristics among high school students. Methods: A cross-sectional descriptive study was conducted on 12th-grade students at Hermann Gmeiner Inter-level School, Hanoi. Results and Conclusion: The prevalence of malocclusion and occlusal abnormalities among students was relatively high. Most participants demonstrated Angle Class I molar and canine relationships on both the right and left sides. Maxillary midline deviation was observed in 13.2% of students, including 7.1% deviating to the right and 5.1% to the left. Mandibular midline deviation was found in 53.2% of students, with 25.6% to the right and 27.6% to the left. The majority of dental arches (both upper and lower) were oval-shaped. Deep bite was present in 23.1% of students, open bite in 30.5%, increased overjet in 17.9%, dental crowding in 47.4%, and reverse bite or crossbite in 19.2%. The prevalence of tooth number anomalies was low, accounting for only 6.4%.
