The purpose of this study was to estimate and compare the maturation stages of permanent teeth in different facial patterns in Rajasthan population. Pre-treatment lateral cephalograms and orthopantomogram of 90 subjects (30 horizontal, 30 vertical and 30 average growth patterns with subgroup of male and female in horizontal, vertical and average growth pattern), with 8 – 16 years of age, were selected from the patients records who had reported to the Department of Orthodontics & Dentofacial Orthopaedics, Darshan Dental College and Hospital, Udaipur. Lateral Cephalograms were traced manually and orthopantomogram were used to get the overall dental maturity score by adding the value of left eight mandibular teeth. Student’s t test was used to compare the maturation of chronological age and dental age in horizontal, vertical and average growth patterns and Pearson’s correlation test was used to found correlation between the group. The results suggest a difference in dental age and chronological age in subject with vertical growth patterns. Vertical female growers showed early dental age maturation compared to chronological age. There was insignificant difference present in dental age and chronological age in horizontal growth patterns and average growth patterns. Insignificant intergroup difference was found in dental age between horizontal vs vertical, horizontal vs average and vertical vs average growth patterns. Subjects with vertical female growth patterns shows early dental age maturation than chronological age. Sn-Go-Gn, lower anterior facial height and Jara back’s ratio are highly significant in determining growth patterns. There also exists strong correlation between dental age and chronological age in horizontal, vertical and average growth patterns in male and female subgroup.
