Abstract

Purpose: Dental age assessment is one of the most reliable methods of chronological age estimation used for criminal, forensic and anthropologic purposes. This study aimed to determine how accurate it was to estimate the chronological age by looking at the dental age measured with the Nolla and Demirjian methods in a Turkish sample, based on the variables of gender and age-group.

Materials and methods: A retrospective study was performed on panoramic radiographs of 1587 subjects (774 females and 813 males), aged 3-17 years. The mean dental age according to the Demirjian and Nolla methods were compared to the mean chronological age (CA). Also, the percentage value of prediction of CA was determined by using the both methods.

Results: An under-estimation of the chronological age was observed by using Nolla's method (males -0.003, females -0.32, both -0.16) and an over-estimation of the dental age was observed by using Demirjian's method (males 0.61, females 0.75,both 0.68).

Conclusion: Nolla's method was more accurate in the CA estimation than Demirjian's method in Eastern Turkish population.

Demirjian和Nolla方法在东土耳其3-17岁儿童年龄估计的准确性。

目的:牙龄评估是一种最可靠的实足年龄估计方法，用于刑事、法医和人类学目的。这项研究的目的是根据性别和年龄组的变量，通过观察用Nolla和Demirjian方法在土耳其样本中测量的牙齿年龄，来确定估计实足年龄的准确性。材料与方法:对年龄3-17岁的1587例患者(女性774例，男性813例)的全景x线片进行回顾性研究。将Demirjian法和Nolla法测定的平均牙龄与平均实足年龄(CA)进行比较。并通过两种方法确定了CA预测的百分比值。结果:Nolla法对实足年龄的估计偏低(男性-0.003，女性-0.32，均为-0.16)，Demirjian法对牙龄的估计过高(男性0.61，女性0.75，均为0.68)。结论:在东土耳其人群中，Nolla法比Demirjian法估算CA更准确。
