Abstract
Summary
Objective: To assess the characteristics of midpalatal suture ossification using cone-beam computed tomography (CBCT) in Vietnamese people. Subject and method: In the present cross-sectional study, the CBCT images of the maxilla in 120 Vietnamese subjects (60 males, 60 females) with an age range of 5 to 65 years, were evaluated. The CBCT images were evaluated in the axial cross-sectional slice at 1mm intervals to determine morphology and the maturation stage of the suture and its degree of ossification. The five developmental stages that were observed were as follows: Stage A, a direct line without disturbances; stage B, a scalloped appearance in the suture; stage C, two parallel lines with a scalloped appearance that were connected at some points; stage D, ossification only in the palatine bone; stage E, complete ossification of the suture. Descriptive statistics were used to analyze the data. Result: This study was determined in 60 males and 60 females with the mean ages of 24.90 ± 13.89 and 24.47 ± 14.34 years, respectively. Stage B was noted in the early childhood period (group I: Under 15 years old) at the rate of 45%. Stage C, D was present mainly in group II (from 15 to 30 years of age) with 37.5% and 35%, respectively. Stage D, E were the most common in group III (over 30 years), without any patient at stage A, B. The average length of the midpalatal suture was 44.72 ± 4.11mm, there was a significant difference between groups in gender. Conclusion: The midpalatal suture ossification increased with age. In group 15 - 30 years, this rate was approximately 40%, but in group over 30 years, this rate was significantly higher, at the rate of 92%.
