2.2.2. Analysis of the width and depth of wrinkles by optical coherence tomography (OCT).

Before treatment and after 1 month, molds of the frontal lines will be made with light condensation silicone (Clonage, DFL Indústria e Comércio, RJ, Brazil). The silicone mold obtained will be poured into special plaster in a short time. Plaster models will be sent for OCT analysis and wrinkle width and depth measured before treatment and after 1 month. The models will be made of a special type of plaster, which has greater resistance and fidelity in the reproduction of details when compared to other types (Fig. Face impression with condensation silicone. Pg 11.Silicone and plaster casts for optical coherence tomography analysis. Pg 11.The OCT-CALLISTO tomograph from the Multiuser Center of the Federal University of ABC will be used to obtain the images by OCT. The plaster models obtained before and after the treatment will be evaluated with the technique. First, a visual assessment of the molds will be performed to select a visible wrinkle. The wrinkle position for analysis will be flagged to ensure that the same wrinkle and region will be analyzed before and after treatment. From the selected point, an image will be obtained with the OCT technique (Fig. Image of the wrinkle impression obtained by OCT. Pg 12. OCT = optical coherence tomography.
