Abstract
Abstract Objective The aim of this study was to compare clinical findings obtained in the treatment of gingival recessions using subepithelial connective tissue graft (SECT), acellular dermal matrix (ADM), and enamel matrix proteins (EMP). Material and method Twelve patients with Miller class I and II recession in the canines or upper premolars were randomly divided into groups to receive treatments using SECT, ADM, or EMP. Clinical measurements were performed before and three months after surgical procedures. The data evaluated were as follows: percentage of root coverage, height and width of gingival recession, probe depth, clinical attachment level, and height and thickness of keratinized gingiva. The Kruskal-Wallis test complemented by Dunn’s test was used to perform the between-group, analysis and the Wilcoxon test was used to perform the within-groups analysis. The tests were applied at the 95% confidence level. Result The SECT and ADM groups had a higher percentage of root coverage and greater reduction in the height and width of gingival recessions compared to the EMP group (p<0.05). Conclusion The SECT and ADM are more effective in treating gingival recessions than EMP.
Highlights
Recession of the marginal gingiva tissue is one of the most common periodontal diseases and is defined as atypical migration of the gingival margin with respect to the cementoenamel junction[1]
The objective of this study was to evaluate and compare the clinical findings obtained from treating gingival recessions with subepithelial connective tissue grafts (SECT), acellular dermal matrix (ADM), and enamel matrix proteins (EMP)
Regarding within-group analysis, it was verified that the SECT and ADM groups had a statistically significant reduction in the height and width parameters of the gingival recessions in the three--month period compared with the baseline (p
Summary
Recession of the marginal gingiva tissue is one of the most common periodontal diseases and is defined as atypical migration of the gingival margin with respect to the cementoenamel junction[1]. Gingival recession occurs frequently in young people and adults and is caused by various etiological factors such as inadequate brushing, plaque accumulation, occlusal problems, orthodontics, and tooth loss, among others[1,2]. The acellular dermal matrix is obtained from human skin that has undergone antigen neutralization treatment; it is a non-vital graft that provides architectural support and allows cellular migration to the recipient bed when surgically applied[7]. Another alternative to using a connective tissue graft is to use enamel matrix proteins as a means to increase clinical attachment[8]. The objective of this study was to evaluate and compare the clinical findings obtained from treating gingival recessions with subepithelial connective tissue grafts (SECT), acellular dermal matrix (ADM), and enamel matrix proteins (EMP)
