This research aimed to test the applicability of The London Atlas of human tooth development and eruption in children of the Malaysian population aged 4 to 16.99 years old. The study sample included 523 panoramic radiographs of healthy patients who had attended the Dental Paediatrics Department Hospital Tunku Azizah, Malaysia, between May 2019 and December 2019. The intra- and inter-observer errors were analysed by taking 53 radiographs and evaluating them over 14 days using the interclass correlation and Cohen's Kappa index. A paired t-test was used to compare chronological and estimated age ANOVA F-tests were used to establish if the difference is statistically significant between chronological and estimated age. The range of age estimation fell within a year due to the mean absolute difference of 0.60 years.

In these circumstances, the properties and characteristics of teeth make them incredibly useful for human identification. Dental morphological traits, commonly studied in anthropology, exist in the population with varying frequencies, which makes them very informative. Thus, everyone has their own dental trait profile, that may manifest with greater or lesser frequency in the population. We propose a discriminative method by exclusion for the identification of individuals, based on the evaluation of dental traits, using intraoral 3D images. For this purpose, a group of 10 dental traits was chosen to obtain a personal profile in a population group of 76 individuals. Various scenarios were created to analyze different problem cases, by using matching-exclusion tables. Three individuals (problem cases) with dental trait profiles of very low (1/27703 individuals), medium (1/136 individuals), or high frequency in the population (1/42 individuals) were randomly chosen for the experiment. Using a conservative approach, the most likely candidate for positive identification was determined in eight steps for problem case 1, five steps for problem case 2, and two final candidates were identified in problem case 3, with only one achieving 100% similarity. In contrast, the less conservative approach identified the most likely candidate in four steps for case 1, three steps for case 2, and four steps for case 3. The rarest dental profile did not necessarily require fewer steps. Our work suggests that using the well-known dental morphological traits and recent 3D imaging technology could significantly improve the efficient triage and identification of victims, especially in cases of closed mass disasters.</p>","PeriodicalId":35728,"journal":{"name":"Journal of Forensic Odonto-Stomatology","volume":"43 1","pages":"33-43"},"PeriodicalIF":0.0,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12083885/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144027417","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}

The regulation of this activity goes beyond following these precepts because, in the legal relationship that is established whenever an agreement is made with a patient to carry out the treatment deemed appropriate, a series of duties and obligations begin for each party, translated into a reciprocal contract, in which the non-compliance of one of them may result in a legal claim. The objective of this study was to research most court decisions delivered in this century, in Portugal, regarding the activity of dentists when faced with patient claims and to outline a framework that better allows us to understand the regulation of this activity within the scope of the contracts established with them. This includes identifying the patients' sex, the judicial instance, the area of dentistry, the location of the injury, the type of liability, the characterization of the obligation, the basis of responsibility, the alteration of biological assets, and the outcome of the action while also not neglecting the identification of trends and jurisprudential evolutions, should they arise. A survey of judgments from the Portuguese Superior Courts was carried out, which focused on decisions from the Supreme Court of Justice, Court of Appeal of Porto, Court of Appeal of Lisbon, Court of Appeal of Coimbra, Court of Appeal of Guimarães, and Court of Appeal of Évora. To understand the judgments analyzed in this study, a brief approach to various legal concepts and institutions of interest was conducted. A summary characterization of the factual basis of the injured party's claim and the legal framework applied, as well as subsequent decisions by higher courts regarding the activity of dentists, was also elaborated. It was impossible to identify any relationship between the field of dentistry and the characterization of the obligation and the basis of responsibility, nor between the outcomes of the actions and these two parameters mentioned.
