Abstract(s)
Objetivo: Este estudo piloto teve como principal objetivo avaliar os conhecimentos e a perceção dos médicos dentistas sobre os materiais e peças dentárias sujeitas a altas temperaturas, contribuindo para a sua elucidação e sensibilização acerca de possíveis lacunas existentes na área da Medicina Dentária Forense, essencialmente no método de identificação humana.
Metodologia: Estudo transversal, aprovado pela Comissão de Ética da Universidade Fernando Pessoa. Foi desenvolvido um questionário de autopreenchimento através do Google Forms, divulgado em plataformas digitais. O questionário abrangeu dados sociodemográficos, opinião sobre registos clínicos, sobre peças e materiais dentários numa perspetiva forense e o momento de contacto com a Medicina Dentária Forense. A análise foi realizada com testes não paramétricos e significância de 0,05.
Resultados: Dos 300 inquiridos, a maioria era do sexo feminino (66,3%), com média de idade de 38,7 anos. Portugal e Brasil foram os países com maior número de respostas. Os registos clínicos completos foram considerados extremamente importantes por 92,3% dos médicos dentistas. Os profissionais com menos tempo de experiência valorizam mais as fotografias, enquanto os mais experientes prezam os moldes/modelos. A resina composta e o ionómero de vidro foram considerados mais suscetíveis a alterações de forma e cor. A amálgama foi considerada a mais estável, seguida das coroas cerâmicas e metalocerâmicas. A dentina foi percecionada como mais vulnerável a alterações de cor e forma do que o esmalte.
Conclusão: A opinião dos inquiridos está alinhada com a literatura, exceto na resistência do esmalte face à dentina. O estudo destaca a importância de registos clínicos padronizados e da formação contínua em Medicina Dentária Forense para reforçar o papel do médico dentista na identificação humana.
Aim: The main aim of this pilot study was to assess dentists' knowledge and perception of dental materials and parts subjected to high temperatures, helping to clarify and raise awareness of possible gaps in the area of forensic dentistry, essentially in the method of human identification. Methodology: This cross-sectional study was approved by the Ethics Committee of Fernando Pessoa University. A self-completion questionnaire was developed and distributed via Google Forms. It covered sociodemographic data, opinions on clinical records, dental parts and materials from a forensic perspective, and contact with forensic dentistry. Data analysis used non-parametric tests, with a significance level of 0.05. Results: Among 300 respondents, most were female (66.3%), with an average age of 38.7 years. Most responses came from Portugal and Brazil. Complete clinical records were deemed extremely important by 92.3% of dentists. Less experienced professionals valued photographs more, while experienced ones favored moulds/models. Composite resin and glass ionomer were seen as most susceptible to form and color changes, while amalgam was perceived as the most stable, followed by ceramic and metal-ceramic crowns. Dentin was perceived as more vulnerable to color and form changes than enamel. Conclusion: Respondents' opinions are largely consistent with the literature, with some discrepancies regarding enamel resistance. The study emphasizes the need for standardized clinical records and continuous training in forensic dentistry to strengthen the role of dentists in human identification.
