QUEILOSCOPIA: CASO PERICIAL SIMULADO EMPREGANDO EVIDENCIAÇÃO COM PÓ DE GESSO TIPO IV

Abstract

The cheiloscopic study is a tool used in the field of forensic dentistry, whose objective is to analyze, record and classify human lip characteristics. They are unique characteristics of each human being, which remain unchanged through lifetime. The present study aims to use dental stone type IV to reveal the lip impression of a volunteer patient. The volunteer patient from the Dental Clinic of FSG Centro Universitário was invited to participate in this research by signing the informed consent form. The patient’s lips were photographed and pressed against a black plastic cup. Then, the dental stone type IV was deposited on the surface of the cup. The lip impression was fixed by a transparent adhesive tape on the cheiloscopic sheet adapted from Stamm (2014). The confrontation was made with the photo of the patient's lips and with the photo of the evidence impression. It was possible to identify 35 matching points between the two images. The dental stone type IV powder deposited on the latent lip impression was successful in its disclosure. It was possible to conclude, through this study, that the dental stone type IV powder deposited on a latent lip impression on a black substrate was able to make its disclosure viable and susceptible to a cheiloscopic comparison.
