Objectives This study investigated the association between the apical surface area measurement (ASAM) of impacted mandibular third molars (IMTM) and chronological age at varying impaction levels, as well as ASAM differences among levels. Methods A total of 446 IMTM (227 right, 219 left) from 257 Malaysian patients aged 15.0 to 25.9 years were included and grouped into 0.9-year intervals. All CBCT images were analysed using Mimics and 3-matic software (Materialise NV, Belgium, version 21.0) to calculate the apical surface area. Impaction level was categorised according to the Pell and Gregory classification system. Spearman’s correlation and Welch’s ANOVA were conducted to assess the relationship between ASAM and age and to compare ASAM across the four levels (A, B, modified B/C, and C). Differences between left and right IMTM were assessed using an independent t-test, and analysed with SPSS (version 26). Result ASAM showed an inverse correlation with age (ρ = −0.89, ρ 2 = 0.79), with a median of 4.86 mm2 (IQR: 2.35–11.92). The steepest decline was observed between 17–18 years, followed by a plateau from 21 years onwards. Left and right IMTM were not statistically different (p = 0.53) and subsequently pooled. ASAM increased with impaction depth; however, only level C exhibited significantly larger ASAM than levels A and B (p < 0.001), with an effect size of ω 2 = 0.13, indicating a notable delay in maturation. Conclusions This study demonstrates the relationship between ASAM in IMTM and age, with potential applicability in dental age estimation. However, caution is advised for level C impactions, as the estimated age may be biased.

Background Fire disasters have emerged as one of the most prevalent causes of morbidity and mortality worldwide. Under these conditions, individuals may be exposed to extremely high temperatures. Identifying such human remains in forensic investigations, particularly those subjected to extreme temperatures, is challenging yet crucial. This study aimed to investigate the impact of different temperatures on the morphological and histological features of the human dental cementum, with an emphasis on the agglomeration patterns of tooth cementum annulation (TCA). Results Extracted mandibular premolar teeth (n = 30) were divided into two groups, direct and protected exposure groups. The samples were heated at 300 °C, 600 °C, and 1200 °C for 40 min. Post-exposure morphological measurements and histological examinations were performed to assess the effects of thermal exposure. Distinct temperature-dependent changes in the tooth morphology and cementum structure were observed. At 300 °C, both direct and protected exposure samples exhibited minimal morphological changes with intact and countable TCA. Samples directly exposed to 600 °C exhibited significant structural damage and became extremely fragile, whereas the protected samples demonstrated partial preservation with agglomerated TCA. At 1200 °C, severe fragmentation and micro-fractures were observed, particularly in the directly exposed samples, rendering the TCA counting impractical. The differences in morphological changes between the direct and protected exposure groups were statistically significant (p < 0.05). Conclusions This study highlights the resilience of the posterior teeth and the differential impacts of direct and protected thermal exposure. These results highlight the utility of TCA as a pathobiological marker for assessing the degree of thermal exposure in forensic settings. Moreover, understanding the morphological and histological alterations in dental cementum under varying temperatures can facilitate fire investigations by forensic odontologists.

This study assessed the potential of the foramen magnum (FM) in the Malaysian juvenile population to estimate sex using computed tomography (CT) data. A total of 200 (male = 100; female = 100) CT images of Malaysian individuals aged between 8 and 16 were retrieved. The maximum length (FML) and width (FMW), area (FMA 1 and FMA 2), and index (FMI) of the three-dimensional image of the FM were measured and analysed using Mimics software version 20 (Materialise N.V., Heverlee, Belgium). These metric data were then used to develop sex estimation models through discriminant function analysis (DFA) and binary logistic regression (BLR). The results showed that all measurements in males were significantly higher than in females ( p < 0.001), demonstrating a high potential for accurate sex classification. Additionally, females exhibited a wider FM than males, as indicated by the FM index. Based on univariate DFA analysis, FML and FMA 2 were identified as reliable variables for sex estimation, achieving an accuracy of 68.5% with a low sex bias rate of 1.2%. The multivariate DFA yielded a higher accuracy of 70.5% compared to the univariate analysis. Similarly, univariate and multivariate BLR analyses demonstrated comparable accuracies of 68.5%. Overall, the DFA showed greater accuracy and lower sex bias across all cases, including original and validation samples. This study suggests that FM parameters can complement existing sex estimation methods and be integrated with other techniques to improve skeletal sex determination.
