“…DA estimation is commonly used worldwide and is thought to correlate with CA better than other maturity indicators of a child’s development. 21 Several methods have been introduced to estimate DA depending on either calcification (tooth development) 7,20,22,23 or eruption patterns. 24 Relying on eruption dates when attempting to assess DA is complicated by the fact that tooth emergence may be significantly affected by local exogenous factors, such as infection, obstruction, crowding, and premature extraction of the deciduous predecessor or adjacent permanent teeth.…”

AimsThe aims of this study were to evaluate the applicability of Demirjian’s method for dental age assessment in a group of Egyptian children in Minia city and to develop an age predictive equation suitable for the studied group.Subjects and methodsIn this retrospective, blind, cross-sectional study, 160 dental panoramic radiographs (DPTs) were selected from 420 DPTs from healthy children aged between three and 10 years old from the archived medical files of patients attending Minia University Dental Hospital (MUDH) and evaluated to estimate dental ages.ResultsAge was overestimated for almost all of the studied subjects with an accuracy range from 0.18 to 1.19 years for males and from 0.08 to 0.87 years for females, with the exception of two age subgroups (9–10-year-old males and 10–11-year-old females, for which the mean difference values were −0.06 and −0.008 years, respectively). A Logistic regression was used to generate a suggested formula for dental age estimation.ConclusionsDemirjian’s method may be unsuitable for Egyptian children living in Minia city. Development of a predication equation and the introduction of adaptable conversion tables to transform the maturity score into a dental age for Egyptian children may be suitable alternatives. The validity of the newly developed prediction equation must be tested among all Egyptian children.

“…In Brazil, for example, criminal liability starts at 18 years of age, as determined by articles 228 of the Federal Constitution (Brasil, 1988), 27 of the Brazilian Penal Code (Brasil, 1940), and 104 of the Child and Adolescent Statute (Brasil, 1990 b). Thus, age assessment in situations that cannot determine chronological age is a mandatory procedure (Mohd Yusof et al, 2017). The scientific literature presents different methods to estimate age, especially in young people, and dental analysis stands out in this context (Kanchan-Talreja et al, 2012;Yassin et al, 2020).…”

“…The age estimation procedure in situations that cannot determine chronological age, especially in legal cases, is mandatory (Mohd Yusof et al, 2017). The most reliable and accurate way to correlate the development and growth of an individual is through the degree of dental development (Koshy & Tandon, 1998;Kanchan-Talreja et al, 2012;Figueira Júnior & Moura, 2014).…”

Age is an important factor in the formation of the uniqueness of individuals. The procedure for assessing age in situations that cannot determine chronological age, especially in court cases, is mandatory. The literature presents different methods to estimate the age of individuals because civil and criminal majority at 18 years is a milestone in Brazil and other countries. Thus, age estimation through the analysis of dental mineralization stages is important, as it is rarely affected by exogenous or endogenous factors. This study evaluates different methods used to estimate age through dental mineralization and its forensic contribution. The following databases were used: PubMed, Medline, Scopus, Web of Science, and Google Scholar, using the descriptors "age estimation", "dental age estimation", and "forensic dentistry", both isolated and combined. It was verified the reliability of the analysis of dental mineralization stages for age estimation. Some of the methods used for this purpose have not been tested in Brazilian individuals. There are no up-to-date data on mineralization stages of permanent teeth for this population. Thus, current and specific data from the Brazilian population are required because the results to be obtained from new studies could benefit society, assisting the clarification of Justice in real-life situations.

“…The scientific literature recommends calculation of dental age as the best method for age estimation in children, for whom there is a high correlation between chronological age and tooth growth [ 2 ]. Furthermore, dental age estimation has the least error in children [ 3 ] and has been found to be more useful than chronological age when planning orthodontic treatment [ 4 ].…”

Age estimation based on Willems method versus country specific model in Saudi Arabia children and adolescents

et al. 2021

Background The aims of this study were to create a method for estimation of dental age in Saudi children and adolescents based on the Willems model developed using the Belgian Caucasian (BC) reference data and to compare the ability of the two models to predict age in Saudi children. Methods Development of the seven lower left permanent mandibular teeth was staged in 1146 panoramic radiographs from healthy Saudi children (605 male, 541 female) without missing permanent teeth and without all permanent teeth fully developed (except third molars). The data were used to validate the Willems BC model and to construct a Saudi Arabian-specific (Willems SA) model. The mean error, mean absolute error, and root mean square error obtained from both validations were compared to quantify the variance in errors in the sample. Results The overall mean error for the Willems SA method was 0.023 years (standard deviation, ± 0.55), indicating no systematic underestimation or overestimation of age. For girls, the error using the Willems SA method was significantly lower but still negligible at 0.06 years. A small but statistically significant difference in total mean absolute error (11 days) was found between the Willems BC and Willems SA models when the data were compared independent of sex. The overall mean absolute error for girls was slightly lower for the Willems BC method than for the Willems SA method (1.33 years vs. 1.37 years). Conclusions The difference in ability to predict dental age between the Willems BC and Willems SA methods is very small, indicating that the data from the BC population can be used as a reference in the Saudi population.
