| Desfecho esperado 1: The objective of this study is to qualitatively evaluate the somatosensory sensitivity of areas that received subepithelial connective tissue grafts, of areas palatal donors of these grafts and assess whether there is a correlation with lifestyle. The evaluation will be verified using the qualitative sensory evaluations test, the Douleur Neuropathique 4 questionnaire and the Two-point Acuity Test. Qualitative sensory evaluations (QualST) were conducted in grafted areas compared to adjacent non-grafted areas and in donor areas compared to adjacent areas without intervention at three time points (baseline and after 3 and 6 months). Assessments of adjacent non-intervened areas are essential for intrapersonal comparison of somatosensory characteristics, validating the methodology employed. The protocol was performed using a flexible cotton swab, bristles of a toothbrush, a metal spatula (previously immersed in a container of ice-cold water), and a wooden stick. These instruments assessed dynamic tactile, cold thermal, and painful sensations. Participants were asked to report hypo (hyposensitive: -1), hyper (hypersensitive: +1), or normosensitivity (normosensitive: 0) when comparing the surgical areas (donor and recipient sites) to adjacent non-intervened areas. The Douleur Neuropathique 4 questionnaire was administered at 3 and 6 months postoperatively to assess items related to painful or non-painful sensations, using descriptive terms such as burning, painful cold sensation, electric shock, prickling, and tingling. For non-painful sensations, descriptors such as burning, electric shock, tingling, numbness, and itching were also employed. Furthermore, in the case of a positive response to painful or non-painful sensations, the frequency and duration were reported, as well as whether induced by brushing or chewing. The questionnaire also included a visual analog scale regarding the impact of these painful or non-painful sensations on the ability to | — |
