Abstract Dental age estimation is required in various clinical and scientific disciplines including Paediatric Dentistry, Orthodontics, Archaeology, Palaeontology and Forensic dentistry. The aim of the study was to assess and compare the accuracy of Willems, London atlas and Cameriere methods for age estimation among children and adolescents based on degree of teeth development, stage of teeth eruption combined with pattern of teeth development and degree of apex closure. The study was conducted on panoramic radiographs of 400 healthy Egyptian children and adolescents (200 boys and 200 girls) aged 5 to 15 years, who were selected from outpatient clinics, Faculty of Dentistry, Tanta University. chronological age for each participant was calculated by subtracting date of birth from date of radiograph and the real age was blinded from the researcher. In Willems method, panoramic images were recorded on computer files then the seven mandibular left teeth excluding the third molar had been scored as ‘0’ for absence of calcification, and ‘A’ to ‘H’, depending on the stage of calcification. Each letter corresponds to a score which is the dental age fraction using tables for boys and girls then by summing the adapted scores for the seven left mandibular teeth directly had resulted in the estimated dental age. |
