A Test of the Demirjian method of dental ageing using a mixed population sample from Northern Ontario

摘要: AbstractDentition is commonly used to determine age because disease and nutritional factors minimally impact dental maturation. This study evaluated the use of Demirjian’s method estimating for a population from Sudbury, Ontario, Canada. A sample 245 panoramic radiographs, taken male female children aged 5–16 years varying ancestries, was collected two local practices. Eight radiographs were excluded due distortion or congenitally missing teeth. The results indicate general over-estimation across all ages, with only significant under-estimation evident in 15 16 year-olds. Inter- intra-observer agreement has been documented both boys girls. yielded Sudbury-specific set standards applying ageing.
