This university extension project aimed to verify the knowledge of athletes about dental trauma, the prevalence and type of trauma that occurred in sports, previous use of mouthguards and to evaluate the impact of educational/preventive actions implemented in this population. The study was divided into 1) Application of Questionnaire 1 (n=94); 2) Clinical examination and manufacture of mouthguards; 3) Lecture on trauma; 4) Application of questionnaire 2 (n=40). The data were submitted to descriptive analysis and Fisher's exact test, with a significance of 5%. Athletes showed little knowledge about dental trauma. The prevalence of trauma and previous use of the protector were higher in athletes in the fighting sports category (p<0.05). After the lectures, the athletes showed improvement in knowledge about trauma and high adherence to the use of custom-made mouthguards. These results show how extension projects have a positive impact, changing the reality of the population.
Several radiographs are taken during endodontic treatment, thus providing a large number of images with individual characteristics that can be used for forensic identification of an individual. This study aimed to review the literature related to the use of endodontic radiographs in the identification of cadavers. A bibliographic search was carried out in the following databases: PubMed, Scielo, Periódicos Capes, and Web of Science. The keywords used were: forensic dentistry, endodontics, dental radiography, forensic identification. In total, 24 articles related to radiography in the identification of cadavers were found. Among them, 8 studies were selected for including endodontic radiographs for this purpose, comprising different types of studies: case reports of forensic identification through endodontic radiography (4); “in vitro” studies on the influence of high temperatures on endodontic materials and their radiographic images (2); a literature review on how radiographs can be used for identification (1); a comparative study between antemortem and post-mortem endodontic radiographic images (1). Overall, the present study showed that endodontic radiographs have a significant amount of information that can be used to identify a cadaver. Therefore, it is important to perform and store radiographs properly and for long periods. Literature related to the subject is still scarce and further studies are needed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
