Evaluating the Reliability of Three Different Dental Age Estimation Methods in Visakhapatnam Children

Abstract

ABSTRACT%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 Demir-jian'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.How to cite this article: Patnana AK, Vabbalareddy RS, Vanga NRV.

Dental age estimation of Omani children using Demirjian's method

“…The Omani laws and penal codes associated with children are set at certain age thresholds, but there are cases where the actual age is unknown and age assessment of the victim is required by the courts to make decisions. It is hoped that the findings of the current study can inform efforts at forensic age determination by the Omani Government in either employment- or marriage-related situations (Patnana et al, 2014, Panchbhai, 2011, Nik–Hussein et al, 2011, Smith and Brownlees, 2011, Karaarslana et al, 2010), or in determining the age of crime victims.…”

“…Moreover, the current geopolitical status of the world has resulted in a rise in the cases of children with no proof-of-identity documents such as a certificate of birth (Ritz-Timme et al, 2000). Different methods have been developed to estimate age; these include using skeletal age, morphological age, secondary sex characteristics age and dental age (Patnana et al, 2014). Of these methods, the latter is seen as the most valid method for age estimation (Bolanos et al, 2000).…”

Age estimation of teenagers from Monterrey (Mexico) by the evaluation of dental mineralization after multi-slice helical computed tomography

“…This was an observational, cross-sectional, and analytical study, which evaluated teenagers and adolescents (age [14][15][16][17][18][19][20][21][22], with residency in the metropolitan area of Monterrey (Nuevo Leon, Mexico), of either gender, and who had at least one third molar formed. Monterrey is a cosmopolitan city in north-eastern Mexico, with over 4 million inhabitants.…”

Demirjian approach of dental age estimation: Abridged for operator ease

“…[2] The calcification of a tooth is divided into eight stages, and each stage has been designated a particular score which is different for boys and girls. [2] Although numerous studies have been done utilizing this method in different ethnic populations,[6789] the most commonly witnessed drawback is that the method is time consuming[2] and less user friendly as numerous tables have to be referred to. Thus, the authors felt the need to simplify this tedious process and prepare a comprehensive chart compiling data from all the original tables of Demirjian (DAEcc) and test its interpretation and ease of applicability by undergraduate BDS students.…”
