There are few studies comparing xenogeneic acellular dermal matrixes (XDMs) with connective tissue graft (CTG) to treat single gingival recession (GR). The present study involved a reanalysis of previous studies and comparison of CTG or XDM to treat single RT1/GR.Fifty patients from three previous randomized clinical trials treated either by CTG (n = 25) or XDM (n = 25) were evaluated after 6-month. Clinical, patient-centered, and esthetic parameters were assessed. Pearson's correlation and regression analyses were also performed.Greater recession reduction (RecRed), percentage of root coverage (%RC), and complete root coverage (CRC) were observed in the CTG group (p ≤ 0.02). Gingival thickness (GT) and keratinized tissue width (KTW) gains were higher in the CTG group. The CTG group showed better esthetic at 6-month. Logistic analyses reported that GT([OR] = 1.647CTG was superior for treating RT1/GR, providing better root coverage outcomes and tissue gains over time. GT, PH, and graft type were classified as predictors of CRC.CTG presented better outcomes to treat single RT1 gingival recession when compared to the XDM.

This study compared the use of two types of XM (collagen matrix [CM] and xenogeneic acellular dermal matrix [XDM]) associated with the coronally advanced flap technique (CAF) to treat single gingival recessions. Methods: Seventy-five patients presenting single RT1 gingival recession were treated by CAF (control group, n = 25), CAF+CM (test group 1, n = 25), or CAF+XDM (test group 2, n = 25) and completed 6-month follow-up. Clinical, patient-centered, and esthetic assessments were performed and intra- and intergroup differences were analyzed. Results: At 6 months, the mean recession reduction for CAF, CAF+CM, and CAF+XDM was 2.4 ± 0.8 mm, 2.4 ± 0.9 mm and 2.1 ± 0.8 mm, respectively (P > 0.05). The corresponding mean percentage of root coverage was 78.9% ± 26.2% for CAF, 78.0% ± 28.5% for CAF+CM, and 65.6% ± 26.9% for CAF+XDM (P > 0.05). Dentin hypersensitivity and esthetic conditions showed significantly improvements in all groups. Test groups presented significant gains in gingival thickness (GT; CAF+CM: 0.4 ± 0.3 mm; CAF+XDM: 0.4 ± 0.2 mm) compared to the control group (CAF: 0.0 ± 0.1 mm; P

No. of bitstreams: 0 Previous issue date: 2020-12-16 Introduction: Gingival recession (GR) is a prevalent problem that is related to esthetic demands and dentin hypersensitivity. Frequently, GR is associated with non-carious cervical lesion (NCCLs) forming a combined defect (CD), which requires restorative and surgical treatment. Connective tissue graft procedures allow predictable root coverage but can result in patient discomfort. Case Presentation: This first case report describes multiple GRs associated with B+ NCCL at teeth #4 and #6 of a 27-year-old patient with a thin periodontal phenotype. The aim of this report was to evaluate the 6-month outcome of a new volume-stable collagen matrix (VCMX) combined with modified coronally advanced flap (MCAF) and partial restoration to treat CDs. After 6 months, significant improvement was observed regarding CD coverage (69.05%), recession reduction (2.25 mm), gingival thickness gain (0.74 mm), and keratinized tissue width gain (0.75 mm). In addition, excellent esthetic evaluation and patient comfort were achieved by using the biomaterial. Conclusion: VCMX associated with MCAF and partial restoration may be an option to treat multiple recession defects plus B+ NCCLs.

No. of bitstreams: 0 Previous issue date: 2020-01-01 Background: This study was conducted to assess the clinical, immunological, and patient-centered outcomes of microcurrent electrotherapy on palatal wound healing. Methods: This was a parallel, double-masked randomized clinical trial, in which 53 patients with ridge preservation indications were selected and randomly assigned to one of two groups. In the control (sham) group (n = 27), palatal wounds, after free gingival grafts (FGG) harvest, received sham application of electrotherapy. In the test (electrotherapy treatment [EE]) group (n = 26), palatal wounds, after FGG harvest, received application of microcurrent electrotherapy protocol. Clinical parameters, patient-centered outcomes, and inflammatory markers were evaluated, up to 90 days postoperatively. Results: The EE group achieved earlier wound closure (P
