Verificação da praticabilidade e da unicidade na queiloscopia e na palatoscopia como métodos de identificação humana

Abstract

Introduction: In forensic dentistry, the oral cavity plays a very important role because of the unique anatomy. The cheiloscopy and palatoscopy are self and accurate methods of identification. Objectives: The objectives of this research were: a)assess the feasibility of techniques b) assess the uniqueness of the sample c) draw a profile of wrinkles and furrows lip palate of students of Dentistry, UERN. Methods: Impressions on the palate were made with stocks trays and alginate and making the study model was made with plaster type III. To obtain the lip prints were used lipstick red color, a sheet of white paper and a glass plate. To sort the lip prints it was used the classification system of Suzuki and Tsuchihashi. For the classification of palatal rugae was the system used Martin dos Santos. Results: Altogether 60 samples were collected, with 30 lip prints and 30 models with palatal rugae. The palatal rugae winding type were found with higher occurrence. The highest occurrence labial furrows were bifurcated type. Conclusions: The cheiloscopy and palatoscopy are applicable human identification techniques, but it is necessary that more studies be conducted so that they are used more frequently among competent organs of investigations. The techniques were feasible and the samples were singular. A higher occurrence of winding palatine rugae and a predominance of bifurcated labial grooves were found.
