COMPARISON OF THE DENTAL MATURATION BY DEMIRJIAN’S METHOD AMONG THE THREE SAGITTAL FACIAL PATTERNS

Abstract

Objective: To compare the dental maturation by Demirjian‘s method among the three sagittal facial pattern.

Material and Methods: A cross sectional study was conducted at Orthodontics department of Khyber College of Dentistry from the January 2017 to June 2017 using a sample of 75 subjects who had all their permanent teeth excluding third molars visible on the panoramic radiographs, regardless of the developmental stages of the teeth, having age between 8 and 16 years were included this study. Each Skeletal class comprised of 25 subjects. Cephalometric parameter ANB and Witt’s appraisal were used to classify sagittal classification. Dental maturity score and dental age determination were made by a single examiner, using the method suggested by Demirjian et al using Panoroma. Data were analyzed using SPSS version 20.0. ANOVA test was applied to compare dental age among three sagittal classes of malocclusion.

Results: Out of total 75 participants, n=33(44%) were males andn n=42(56%) were females. The age range was 9 to 15 years with mean age of 11.706±2.058 years. The most common age was 9 and 12 years followed by 11 and 13 years. Mean dental age was 6.1 years in skeletal class I and 5.8 years in skeletal class II while 5.7 years in skeletal class III. So the mean and standard deviation of dental age were closer to each other. There was no difference in three sagittal class of malocclusion which was statistically non-significant (P=0.574).

Conclusions: Dental maturation does not differ in various sagittal classes of skeletal malocclusion.
