Objective: The purpose of this study was to evaluate the maturation of mid-palatine suture (MPS) in Indian adolescents between 11 and 18 years using cone-beam computed tomography (CBCT).
Materials and methods: Cone-beam computed tomography (CBCT) images in axial sections of MPS from 80 adolescents (43 males and 37 females) were classified using a scale denoting the maturation stage of MPS (A, B, C, D, and E). The Chi-squared test was applied to evaluate suture stages by sex and age-groups.
Results: Stage A was observed in only four subjects of 11 years. Stage B was present in all age subjects but was more prevalent in subjects <14 years of age. Stage C was the most prevalent in subjects up to 16 years of age. Stages D and E showed low prevalence rates and were found more in subjects in the 17–18-year age-group.
Conclusion: Although the maturation of MPS increases with age, age cannot be considered the only factor. The satisfactory prognosis of orthopedic expansion mechanics can be expected up till stage C, as the bony fusion of MPS begins from stage D.
