“…The skulls were collected in and around Kolkata from the early 1970s to the late 1980s, and were imported legitimately from India for academic research and education. As the identity of the specimens were not known; sex and age were estimated using forensic anthropological methods: sex, according to Krogman and Iscan (1986) and Singh et al (2015), and age, according to Gazge et al (2018). The GAs of these mandibular specimens were measured using a mandibulometer (GPM Anthropological Instruments, Zurich, Switzerland) and categorized into two groups: the L-GA group, where GA ≤ 120° (n = 13 mandibles), and the H-GA group, where GA ≥ 125° (n = 16 mandibles).…”

This study aimed to reveal differences in the mandibular corpus and ramus measurements, volume (VOM), and gross weight of the mandible (GWOM) between the low and high gonial angles (L-GA and H-GA, respectively) in adult mandibles, and to evaluate the correlations between GAs and the measurement variables. Twenty-nine dried adult human complete dentate mandibles (L-GA ≤ 120°: 13 mandibles; H-GA: 125° ≥ GA: 16 mandibles) were measured using a lateral radiograph image-processing system, digital Vernier calipers, and an electric balance. The total length of the mandible (TLOM), corpus length (mental foramen– gonion [MeF’-Go’], mental foramen–mandibular foramen [MeF’-MaF’], and mandibular foramen–gonion [MaF’-Go’]), inter-ramus (bicondylar, bicoronion, and bigonion) widths (BiCoW, BiCorW, and BiGoW), GA width (GAW), condylar perpendicular height (CPH), the VOM, and GWOM were measured. Data were assessed using the exact binomial test, Mann–Whitney U test and Pearson’s correlation coefficient test. The MeF’- Go’ and MaF’-Go’, three inter-ramus widths, GAW, CPH, VOM, and GWOM in the L-GA group were significantly larger than those in the H-GA group. Significant negative correlations were found between GA size and multiple variables other than TLOM and BiCorW. Therefore, GA size was closely related to the enlarged morphometric dimensions of both the GA and the mandibular ramus in the posterior region of the mandibular corpus, as well as the volume and weight of the mandible, but it was not related to TLOM. These results indicate that the evaluation of GA size is useful for strategic dental treatment.

Background Age estimation has been an integral part of forensic science, and age estimation by dental means is by far the most commonly employed method. Dental age estimation in children is more accurate and straightforward as most methods use the chronological stages of odontogenesis that are highly systematic, reducing the chances of dispersed results. In contrast, estimation of age in adults becomes tricky and less accurate with varied approaches since tooth formation is already complete. Main body The methods of adult dental age estimation have come a long way from a calculated guess based on crude visual observation of teeth to radiological methods and to more recent sophisticated methods. Technological advances have opened up molecular and genetic methods by utilizing DNA methylation and telomere length to improve the accuracy of age estimation by reducing error chances. Conclusions Although dental age estimation methods in children and adolescents have been extensively reviewed, various adult age estimation methods are not reviewed as a whole. The aim of this review is to appraise the evolution of dental age estimation methods in adults over the years from mere visualization of dental attrition to employing more sophisticated means such as radioactive carbon dating and genetics. This comprehensive review also attempts to add an account of the accuracy and suitability of various adult dental age estimation methods.

“…As long as dental age estimation is concerned, several methods have been proposed for assessing dental development, which is generally referred to as dental age 16 . Morphologic and radiographic methods (Cameriere’s, Schour-Massler’s, Demirjian’s, and Kvaal’s method) are useful in living humans 17 , whereas biochemistry methods (Gustafson’s and Johanson’s method, Bang and Ramm method, aspartic acid racemization and cemental annulation technique) are useful in dead victims 18 .…”

BackgroundInability to predict dental age accurately has long been the Achilles heel of pediatric dentistry. Whilst dental age has an important aspect in clinical practice, saliva can be one of the most practically important diagnostic tools to estimate biological age.AimsThis study was aimed to analyze a correlation between chronological age, dental age, and salivary alkaline phosphatase in Indonesian children aged 8-14 years.MethodsThis study was an observational study with cross-sectional design. Twenty healthy children (10 boys; age 10.504 ± 1.895 years) were selected by a consecutive sampling. Chronological age was assessed by recording date of birth. Dental age was assessed by orthopantamogram following Demirjian’s method. Salivary samples were collected by passive drool method and estimation of alkaline phosphatase was done by autoanalyzer.ResultsNormality test was assessed using Kolmogorov-Smirnov and Shapiro-Wilk test. Statistical analyses were assessed using Spearman’s rank-order correlation coefficients. Results are presented as mean ± standard deviation (SD). Mean chronological age was10.504 ± 1.895 years, mean Demirjian’s score was 91.74 ± 5.972, and mean salivary alkaline phosphatase was 291.563 ± 115.135 pg/ml. There is a very strong positive correlation between chronological age and dental age (r=+0.804; p<0.001). On the contrary, levels of salivary alkaline phosphatase was negatively correlated to dental age (r=-0.780; p<0.001) and chronological age (r=-0.508; p=0.022).ConclusionsThis study showed a strong correlation between dental age, chronological age, and salivary alkaline phosphatase; hence, estimation of dental age and salivary alkaline phosphatase in Indonesian children during early and late childhood has significant meaning to chronological age.
