Impacto de tratamentos para recobrimento radicular com tecido conjuntivo e uma matriz de colágeno em fatores centrados nos pacientes com recessões gengivais

Abstract

Gingival recessions may cause dentin cervical hypersensitivity and esthetical discomfort, may having an adverse impact over the quality of life related to oral health and a social, psychological and emotional impact over the daily life of each patient. AIM: This study aims to evaluate the impact of root coverage treatments using subepithelial connective tissue graft and collagen matrix on patient-related factors whom lodge Miller´s gingival recession class I and II with 6 months of support. METHOD: This clinical trial, controlled, randomized, doubleblind, split-mouth, evaluated 32 patients with Miller´s bilateral gingival recession class I or II subjected to a root coverage procedure with subepithelial connective tissue (control) and to a collagen matrix (test). The evaluated baselines were post-surgery pain, dentin cervical hypersensitivity, esthetic, degree of satisfaction and quality of life after 03 and 06 months of the procedure. The data were statistically analyzed through Split-Plot Analysis of Variance and One-Way Analysis of Variance followed by Bonferroni test as a post-test, being pre-established with a significance level of 5%. RESULTS: The patients reported an average age of 29.53 years-old (22-53, ± 7.12) and were equally distributed in terms of sex. It was observed significant differences statistically on the parameters of post-surgery pain, dentin cervical hypersensitivity, esthetical and patient satisfaction, inside each group of treatment by the evaluated periods (p<0.001), although, without any significant differences between the groups. The analysis revealed improvements on the quality of life of the patients after 03 and 06 months of the surgical procedure (p<0.001), having the measures of physical pain and psychological discomfort with the best results. CONCLUSION: Both treatments resulted in a significant difference on the adverse impacts in the quality of life and in the patient-related factors after 06 months. It has not been found significant differences statically between both root coverage techniques correlated to any evaluated parameter. The collagen matrix represents a possible alternative to subepithelial connective tissue graft.
