Dental age is important for treatment planning in the specialities of pedodontics and orthodontics. Although, Demirjian\'s method was considered standard for dental age estimation, it may not be reliable for all population.
Aim: The goal of the study was to evaluate the reliability of Demirjian\'s, Haavikko\'s and Willems method of dental age estimation methods in Visakhapatnam (Andhra Pradesh, India) children.
Study design: One hundred and two children of 6 to 14 years old who underwent panaromic digital radiography for routine diagnostic purposes were included. Dental age was calculated using Demirjian\'s, Haavikko\'s and Willems methods and compared with chronologic age for each patient.
Results: Dental age showed a significant overestimation by Demirjian\'s method with a mean difference of 0.55 year and underestimation by Haavikko\'s and Willems methods with a mean difference of 1.95 and 0.20 year respectively when compared with chronologic age. The mean difference between dental age and chronologic age was not significant in Willems method which shows a close relation between dental and chronologic ages.
Conclusion: The dental age estimation by Willems method is found to be more accurate than Demirjian\'s and Haavikko\'s methods in Visakhapatnam children.
