HYALURONIC ACID LIP AUGMENTATION AND ITS EFFECT ON HUMAN IDENTIFICATION BY CHEILOSCOPY: A CASE REPORT

Resumo

Cheiloscopy is a human identification technique that consists of studying the lips and their characteristics, such as their thickness, the arrangement of the labial commissure, the position of the grooves and their classifications, as well as recording the impressions produced by them on various supports. Lip augmentation with hyaluronic acid (HA) fillers has become very popular in recent years, especially since facial harmonization was included as a dental specialty. The aim of this study was to verify whether lip fillers with HA have implications for cheiloscopic studies, by means of a clinical case report. A 37-year-old female patient with leukoderma took part in the study. Photographs were taken and measurements of lip thickness, lip commissure layout and lipstick impressions were taken before the lip filler, 15 days after the application of 1 ml of HA and 15 days after the full 2 ml of HA filler. The results of the study suggest that lip filling with HA can interfere with the cheiloscopic method, as there was a change in the architecture of the lips, the layout of the labial commissure, improved contour, cupid's bow and filter, with a significant change in the thickness of the upper and lower lips of approximately 42% in relation to the previous volume. As for the pattern of the lip furrows, there was no change in the designs, however, the quality of the lip impression was affected due to the effect produced by the HA
