The overall correct sex estimation was achieved in 58.5% of the cases. The predictive accuracy or assessment was higher for females compared to males. Consequently, the posterior ramus of mandible or mandibular ramus flexure can be considered as supplementary rather than a definitive means of sex determination.

Results showed that forensic dentists are more psychologically or emotionally affected by child abuse cases and least affected by age estimation cases. Most experienced forensic odontologists reported the lowest scores of discomforts. Males were more comfortable than women in dealing with stress. 80.77% (n= 21) of the students have not experienced any behavioural changes following mortuary sessions but 19.2% (n= 5) witnessed stress.

A pilot study.","authors":"E Alvarado Muñoz, S Rm Requena Calla","doi":"","DOIUrl":"","url":null,"abstract":"Introduction: Age estimation is an important forensic resource in human identification. Amongst the different methods of dental age estimation, root dentin transparency (RDT) is considered a reliable parameter, as well as an indicator of chronological age at time of death in human adult remains. The aim of this study was to estimate the age of individuals using the Bang and Ramm method and to derive a new formula suitable for age estimation in the Peruvian population by assessing the length and percentage length of RDT.Materials and methods: The sample consisted of 248 teeth collected from 124 deceased individuals, between the ages of 30 and 70 years. RDT length was digitally measured from sectioned and photographed teeth. Linear and quadratic regressions were made to derive Peruvian formulae and the new formulae were applied to another group of samples (n=30).Results: Data showed a significant correlation (p<0.01) between chronological age and translucency length (Pearson´s correlation=0.775) and percentage length (Pearson´s correlation=0.778). Linear and quadratic regressions for obtaining Peruvian formulae showed that quadratic equations expressed greater determination coefficients. Comparisons between estimated age using Peruvian formulae showed that dental age from percentage of length of RDT a higher percentage of estimates with errors <± 05 and <± 10 years. The accuracy of the new Peruvian formula using the percentage of length of RDT (MAE=7.83) can be considered acceptable.Conclusion: As shown in the results, age estimation using the Peruvian formula derived from the percentage of length of RDT has proven to be more accurate than estimates using the Bang and Ramm method. Thus, it could be used in age estimation for Peruvian individuals, as it is the most accurate methods and provides a larger number of acceptable estimates.","PeriodicalId":35728,"journal":{"name":"Journal of Forensic Odonto-Stomatology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10319099/pdf/JFOS-41-1-19.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9907716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fire is a destructive force capable of inflicting significant damage. Destruction of soft tissue in fire disasters makes victim identification nearly impossible.

Analyzing the precise morphological, stereomicroscopic, histological, and gravimetric findings can extract valuable information from dental evidence in forensic investigations.Materials and methods: Thirty-six mandibular premolar teeth extracted for therapeutic purposes were exposed to high-temperature gradients. Macroscopic, stereomicroscopic, histological, and dry weight analyses were performed at each temperature gradient.Results: The colour of teeth changed from yellowish orange to metallic black bronze to chalky white. Stereomicroscopy showed intact teeth at 100°C, gradual micro-cracks at 500°C, and a fully fractured crown at 900°C. Decalcified sections revealed dilatation of dentinal tubular pattern at 300°C. Dentinal tubules showed appearance of vapour bubbles at 400°C, resulting in loss of typical architecture. In the ground sections, alterations in scalloping nature of dentino-enamel junction, coalescing radicular dentinal tubules, and sand cracking appearance of teeth were noted at 100°C, 300°C, and 900°C, respectively. Significant reductions in the weight of the teeth samples were observed with higher temperatures.Conclusion: From the morphological, histological, and gravimetric changes in a tooth caused by fire, it might be possible to determine the temperature and duration of fire exposure, and the cause of the fire.","PeriodicalId":35728,"journal":{"name":"Journal of Forensic Odonto-Stomatology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10266701/pdf/JFOS-40-3-52.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10007961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
