Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 17, Issue 2
Abstract
AIM AND OBJECTIVE: To check the validity of Demirjian’s method by comparing the chronological age to dental age estimated by Demirjian’s method in Mangalore population. MATERIALS AND METHODS: This retrospective study was done using 62 panoramic radiographs which were collected in the age group of 3- 16 years from the archives. Dental age was calculated using Demirjian's method, and it was then compared with the chronological age of the study population. The obtained data were statistically analysed using paired t test, intra class correlation coefficient and a regression analysis was done using SPSS 13 software. RESULTS: Average chronological age obtained was 11.3081 ±2.57308. Average dental age estimated by Demirjian’s method was 11.2210 ±2.45115. The intraclass correlation coefficient showed excellent agreement between the two. Statistical analysis indicated no significant difference between chronological age and age obtained by Demirjian’s method. The present study indicated that Demirjian’s method is reliable for age estimation in Mangalorean population. Age of subjects can be estimated with a good degree of accuracy using regression equation which was obtained after statistical analysis
