Summary: This umbrella review critically assesses the level of evidence of sex determination in forensic dentistry and provides an overall comprehensive view. The review identifies low-quality systematic reviews and emphasizes the need for well-designed clinical trials and high-standard reviews to corroborate the accuracy of different sex determination procedures in forensic dentistry.

Summary: This study used biometric analysis to accurately determine the sex of Bonelli's eagles using just two measurements. The study included 137 eagles sampled in eastern Spain from 2015 to 2022. The results showed that the lateral tarsus length and dorso-ventral tarsus length were the most effective measurements for sex determination. This non-invasive method has multiple applications in conservation efforts.

Summary: This study analyzed gender differences in the size of permanent maxillary canines using a three-dimensional digital method and tested the accuracy of gender estimation using discriminant function analysis in a Saudi population sample. The results showed that males had larger maxillary canines in terms of mesiodistal width and intercanine distance compared to females, and the difference was statistically significant. Discriminant function analysis demonstrated an overall accuracy of 80.5% in gender prediction, with intercanine distance being the most accurate predictor.

Summary: This study developed and validated a new method for sex estimation using dental morphometric geometric analysis and artificial neural network. By training and validating a classification model based on the sexual dimorphic traits of multiple maxillary teeth, the study achieved a high accuracy rate of 82%.

Summary: For many vertebrates, a single genetic locus initiates a cascade of developmental sex differences, resulting in adults with two phenotypically distinct sexes. However, species with polygenic sex determination have multiple interacting sex determination alleles, allowing for more than two genotypic sexes. In the cichlid fish Metriaclima mbenjii, polygenic sex determination produces modular variation in morphological and behavioral traits, and the evolution or introgression of a newly acquired sex determiner creates additional axes of phenotypic variation.

Summary: Sex estimation is crucial for individual identification in forensic applications. This study developed an artificial intelligence model based on a deep learning network to estimate sex using orthopantomograms (OPG) in northern Chinese subjects. The accuracy of sex estimation using the CNN model was higher for adults (90.97%) compared to minors (82.64%). This model shows promise for automated morphological sex-related identification in forensic science for adults in northern China and provides a reference for minors.

Summary: This study combines geometric morphometric analysis (GMA) and an artificial neural network (ANN) to classify the sex of premolar teeth in Caucasian Italian adults. The method achieved a classification accuracy of 90% for females and 73% for males. GMA combined with ANN showed better sex classification ability compared to previous methods.

Summary: This study aims to determine the role of the mandibular ramus in gender determination using digital orthopantomographs (OPGs). Measurements were performed on 600 OPGs, and the results showed significant sexual dimorphism in the mandibular ramus. Therefore, analysis of the ramus on OPGs can be a valuable aid in gender determination for forensic odontology and anthropology.

Summary: The study introduced a novel Adjusted binary classification (ABC) algorithm that could improve the accuracy of classification in forensic settings while reducing the possibility of incorrect classifications. The experimental results showed that the ABC models achieved accuracy of 95% or above in both the training and testing samples, effectively classifying specimens with specific posterior probability cut-off thresholds for each group.

Summary: This research created an improved metric method using three-dimensional geometric morphometrics to determine sex from human pubic bones. Results showed high accuracy in sex prediction for both whole bones and simulated fragmented remains, with specific landmarks around the ventral arc of the pubic bone performing the best. These results indicate that three-dimensional geometric morphometrics is a valid method for sex determination in forensic anthropology.

Summary: This study demonstrates the use of genome-wide DNA methylation (DNAm) patterns to investigate temperature-dependent sex determination (TSD) species, specifically American alligators, in the face of climate change. Through analyzing DNAm in blood cells of hatchling alligators, sex-associated differentially methylated cytosines (DMCs) and temperature-associated DMCs were identified. DNAm-based models were developed to accurately predict hatchling sex and past incubation temperature.
