Descriptive cross-sectional study was conducted on 93 students from VNU University of Medicine and Pharmacy. For each student, maxillary alginate impression was taken, a diagnostic cast was poured with dental stone, digital impression was taken. Some parameters are measured in DentOne Software: mesial and distal papilla height, clinical crown height, mesial and distal papilla proportion of each maxillary anterior tooth
determine position of the gingival curve characteristic point. The result is the mesial and distal papilla proportion for the maxillary anterior dentition was 41.49% and 41.72%, respectively. In CI, the distance from the gingival curve characteristic point (IP) to x and y axis were 1.12 ± 0.31mm, 2.12 ± 0.53mm in mesial
in distal were 1.07 ± 0.21mm and 1.46 ± 0.30mm. In LI, the distance from IP to x and y axis were 0.87 ± 0.23mm, 1.59 ± 0.39mm
in distal were 0.90 ± 0.21mm and 1.40 ± 0.37mm. In CI, the distance from IP to x and y axis were 1.03 ± 0.23mm, 1.51 ± 0.33mm, in distal were 1.06 ± 0.26mm and 1.94 ± 0.40mm.Nghiên cứu mô tả cắt ngang trên 93 sinh viên trường Đại học Y Dược nhằm khảo sát tỷ lệ giữa chiều cao nhú lợi và chiều cao thân răng lâm sàng và vị trí điểm uốn đường cong nhú lợi vùng răng trước hàm trên.
