ABSTRACT Objective: The aim of this study was to establish reference data on third molar morphology/development for age estimation in Western Saudi adolescents, between ages 14 and 23 years of old. Materials and Methods: The orthopantomograms of 130 individuals (males and females), were examined, and the stage of third molar development were evaluated. Results: Mean ages, standard deviations, and percentile distributions are presented for each stage of development. The mean estimated age for all participants (n = 130) was 219.7 months, and this differed significantly (P < 0.05) from the mean chronological age (226.5 months). Deviations of predicted age from real age showed 28.5% of all participants had their age estimated within 1 year (±12 months) of their chronological age. Most (43%) had their age underestimated by more than 12 months and the remaining 28.5% had their age overestimated by more than 12 months of their chronological age. Differences in left-right symmetry information of third molars were detected and were higher in the maxilla (92%) than in the mandible (82%). For all molars reaching stage “H” most individuals (males and females) were over the age 18 years of old. Males reach the developmental stages earlier than females. Conclusion: Third molar tooth development can be reliably used to generate mean age and the estimated age range for an individual of unknown chronological age. Further studies with large populations are needed for better statistical results.

Background: The evaluation of the chronological age is a practical method in crime investigation field that assists in identifying individuals to treat them as underage or adult. This study aimed to assess the stages of third molars mineralization in relation to chronological age of Iraqi individuals, determine the gender differences and arches (maxillary/mandibular) differences. Materials and Methods: A total of 300 orthopantomograms of orthodontic patients were collected according to specific criteria and evaluated visually. The developmental stages of maxillary and mandibular third molars were determined according to Demirjian method. The chronological age was recorded according to the particular mineralization stages at which it reached considering genders, sides and jaws. Comparisons were done using paired sample and independent sample t-tests. Results: Results showed that there was no statistically significant difference (P>0.05) between maxillary and mandibular third molars. The maxillary third molars reached earlier than mandibular one in stages F and G. There was no significant difference between the mean ages of males and females at each given developmental stage in the maxillary and mandibular third molars except for the stage D in the maxilla and stages D and E in the mandible. The development of third molar teeth on the right and left sides was similar except for the maxillary arch in males when there was a significant difference in stage C and D and stage E in the mandibular arch. Conclusion: The Demirjian method is an excellent approach for age assessment using Orthopantomogram. All of the differences between the current study and other studies could be because of the difference in the populations who were chosen from different geographical areas. Keywords: Age estimation, Demirjian method, third molar, Orthopantomogram, chronological age.

Qualitative Methodologies

Human teeth are among the most distinctive and long lasting features of mammal species. Various quantitative and qualitative methodologies have been developed by the researchers in order to establish an assessment format to determine the correlation between the dental age and the chronological age. The morphological and radiological examinations of third molars make up a part of the orthodontic, pedodontic, forensic odontology and oral surgical treatments and remain the most reliable biologic indicator available for age estimation during the middle teens and early twenties. This age calculation requirement is not only for differentiating the juvenile from the adult status in criminal law cases, but also for chronological age estimation in relation to school attendance, social benefits, employment and marriage.

The Relationship

Molar development is widely accepted as a reliable indicator of chronological age in a forensic context. A quantitative method for age estimation has been proposed by Cameriere et al. based on the relationship between chronological age and the third molar maturity index (I3M), which is the ratio between the two apical pulp widths and the total tooth length. Cameriere’s cut off value of 0.08 was found to be a reliable tool in assessing the threshold of 18 years of age. The aim of this study was to evaluate the accuracy of the I3M in different ethnic populations focusing on its specificity (subjects correctly classified as <18 years based on I3M >0.08) and sensitivity (subjects correctly classified as ≥18 years based on I3M <0.08). A review of 22 scientific articles was performed, representing data from panoramic radiographs of 12,286 individuals (5723 males and 6563 females) from all over the world, including some ethnical subgroups. The I3M showed an overall sensitivity for both sexes ranging from 51.8% to 93.4% and a specificity ranging from 86.2% to 100%. The proportion of correctly classified individuals ranged from 74% to 95%. These results can be useful to refer the age estimation with the margin of error of subjects correctly classified as minors (specificity) or adults (sensitivity), according to sex, ethnicity and geographical distribution. The I3M can be considered a suitable method for estimating adulthood in forensic settings, regardless of sex. However, ethnic group can affect the accuracy.

Dental Radiographs

Unaccompanied migrant children seeking asylum status in the United States are often forced to undergo dental radiographs, or x-rays, to verify that they are younger than 18 years. The application of third molar dental radiographs is methodologically flawed and should not be employed as a determinant of chronological age. Furthermore, the use of such tests without obtaining informed consent from either the youth or an objective advocate is unethical. Finally, the legal and health consequences of these inappropriately applied tests are severe and jeopardize the safety and security of these vulnerable minors.
