Avaliação de rugosidades palatinas através de fotografias intraorais e de modelos de gesso em gêmeos monozigóticos

Abstract

Palatal Rugoscopy is a method that studies the patterns of palatal rugae to establish the identity of a person, based on biological parameters of uniquenes, perenniality and immutability and to the criteria of classifiability and practicality. The general purpose of this study was to demonstrate the existence of the differences of palatal rugae in human identification, considering distinct systems of classification of a sample with monozygotic twins, utilizing intraoral photographs analysis and plaster models photographs. Thus, the rugae were outlined through digital method, according to Carrea System and Martins dos Santos Classification and the photographs of the twins were superimposed. In general, the palatal rugae of monozygotic twins were different from each other. However, the Carrea system presented limitations in the classification of the differences between twins and genres. It is suggested the use of more than one classification technique or analysis methodology (intraoral photographs, model photographs and superimposition of images) aiming to provide more amount of data to conclude more trustful results. Furthermore, this study suggests the realization of new studies with larger samples for verification of associations, as example between genres and other variables.
