Resumo
Introdução: Pesquisas por métodos biométricos auxiliares em perícias têm crescido na Odontologia Legal. Objetivo: Este estudo avaliou a eficácia da rugoscopia palatina na identificação humana. Material e método: Foram utilizados 184 modelos de gesso de estudantes voluntários em Niterói-RJ, para delineamento de suas rugosidades palatinas, sendo classificadas segundo quantidade, direção (sistema de Carrea) e formato individual (sistema de Silva), e comparadas às variáveis demográficas sexo, cor da pele e idade. A análise estatística foi realizada com o teste qui-quadrado para amostras independentes, considerando-se p<0,05. Resultado: Houve maior prevalência de 2-7 rugas em homens. O tipo IV de Carrea e o tipo 1 de Silva foram mais evidentes, porém sem diferenças intergrupos significativas, de acordo com as variáveis propostas. Conclusão: A rugoscopia palatina é uma ferramenta biométrica viável e fornece informações morfológicas individuais relevantes, embora sua análise cega e em tempo único não exiba acurácia na estratificação populacional.

Abstract
Introduction: Researches by auxiliary biometric methods for skills have grown in Forensic Dentistry. Objective: This study evaluated the effectiveness of palatal rugoscopy in human identification. Material and method: They were used 184 plaster models of students volunteers in Niterói, RJ, performing the design of their palatal rugae sorted by amount, direction (Carrea’s pattern) and individual format (Silva’s pattern) and compared to the demographic variables gender, skin color and age. Statistical analysis was performed using chi-square test for independent samples and considering p<0.05. Result: There was a higher prevalence of 2-7 rugae in men. Carrea’s pattern IV and Silva’s pattern 1 were evident, but no significant intergroup differences in accord to the proposed variables. Conclusion: The palatal rugoscopy is a practicable biometric tool and it provides relevant individual morphological information, although its blind and one-time analysis not displays accurancy in population stratification.
