Abstract(s)
Introdução: A mandíbula desempenha um papel crucial na identificação forense devido à sua robustez e características morfológicas que fornecem dados sobre sexo, idade e afinidade populacional. Meios auxiliares de diagnóstico como radiografias panorâmicas e a análise métrica têm sido amplamente utilizadas para estudar essas variações, apesar das limitações de precisão. Com o avanço das tecnologias assistidas por computador, novos métodos quantitativos, como a geometria morfométrica, têm revolucionado a área forense, permitindo uma identificação mais precisa em casos de restos fragmentados ou desastres.
Objetivo: Este estudo teve como objetivo determinar diferenças morfológicas entre os sexos em pacientes adultos através da análise métrica de ângulos em radiografias panorâmicas realizadas na Clínica Dentária da Universidade Fernando Pessoa, com o intuito de obter informações úteis para a identificação humana e novas possibilidades de diagnóstico do sexo.
Métodos: O presente estudo visa analisar radiografias panorâmicas digitais e dados sociodemográficos de pacientes adultos atendidos nas Clínicas Pedagógicas de Medicina Dentária da Universidade Fernando Pessoa nos últimos seis anos, com o objetivo de identificar relações métricas mandibulares associadas ao sexo e à idade. O estudo foi autorizado pela Comissão de Ética da Universidade Fernando Pessoa e pela Direção das Clínicas Pedagógicas.
Resultados: Com uma idade média de 46 anos, variando entre 18 e 91 anos, as mulheres apresentaram um ângulo gónico significativamente maior do que os homens. Também apresentaram ângulos do processo coronoide-côndilo externo e interno estatisticamente maiores. As tendências gerais revelaram que o ângulo gónico e os ângulos externo e interno do processo coronoide-condilar aumentavam com a idade.
Conclusão: O estudo métrico da mandíbula radiograficamente pode ser útil para estimar o sexo de um indivíduo em comparação com normas populacionais já conhecidas.
Introduction: The mandible plays a crucial role in forensic identification due to its robustness and morphological characteristics that provide data on sex, age and population affinity. Techniques such as panoramic radiography and metric analysis have been widely used to study these variations, despite limitations in accuracy. With advances in computational technologies, new quantitative methods such as geometric morphometrics have revolutionised forensic science, allowing more accurate identification in cases of fragmented remains or disasters. Objective: The aim of this study was to determine morphological differences between the sexes in adult patients through the metric analysis of angles in panoramic radiographs taken at the Fernando Pessoa University Dental Clinic, with the aim of obtaining useful information for human identification and new possibilities for diagnosing sex. Methods: The present study analysed digital panoramic radiographs and socio-demographic data of adult patients attending the Clinical Dentistry of the University of Fernando Pessoa during the last six years. The aim was to identify mandibular metric relationships associated with sex and age. The study was approved by the Ethics Committee of the University of Fernando Pessoa and the management of the Clinic. Results: With a mean age of 46 years, ranging from 18 to 91 years, women had a significantly larger gonial angle than men. They also had statistically larger external and internal coronoid-condylar process angles. The general trends showed that the gonial angle and the external and internal coronoid-condylar process angles increased with age. Conclusion: Metric radiographic analysis of the mandible may be useful in estimating an individual's gender when compared to already known population norms.
