Abstract: Tooth formation is widely used to assess maturity and predict age.Within clinical dentistry this formation aids in diagnosis and treatment planning. Chronological age, as recorded by registration of birth date, is referred to throughout an individual’s life. Thisinformation is relevant in medical and dental practice for evaluating developmental progress, for educational purposes and in legal matters, particularly in the application of criminal law. Thepanoramic radiographs of 75 healthy children (40 boys and 35 girls) aged between 5-14 years were selected. Demirjian, Nolla, Haavikko, Williams and Cameriere methods were applied for estimation of age. Theresult of our study have shown that Williams method is more accurate followed by Haavikko, Cameriere, Nolla and lastly Demirjian method. Key words: Age determination % teeth % accuracy % panoramicradiograph INTRODUCTION It is accepted generally that somatic development is related to chronological age and, as a result, measurements of somatic maturity, for example bone age, menarche and height,have been used to estimate chronological age in the absence of accurate age data [1]. Tooth development shows less variability than other developmental features and also low variability in relation tochronological age [2]. Various odontological methods have also been carried out to estimate age, assessing eruption phases within acceptable error limits. Basically, these method define the stages ofmineralization of teeth observed in radiographs and code them according to scores. The most common method for age estimation was published in 1973 by Demirijian, Goldstein and Tanner and subsequently...
