This research aims to evaluate the clinical and histological parametric differences concerning keratinized tissue that result from two regeneration techniques, the subepithelial autologous connective tissue graft (ACTG) and the acellular dermal matrix (MD) of porcine origin, performed on surgical beds on edentulous spaces in an animal model. The parameters of the MD and ACTG groups were compared with samples of the control group (CG) after 15, 45, and 90 days. Nine female white pigs (Sus scrofa domestica) were used, and each animal provided 20 study areas (12 MD and 8 ACTG). At 15 days, the keratin layer thickness in the MD group was greater than those of the ACTG (25.27 vs. 19.95 μm) and the CG (21.2 μm). After 45 days, the MD and ACTG thickness values decreased but were higher than the CG. At 90 days, MD (19.46 μm) obtained a value close to that of CG, and the ACTG decreased to CG (15.53 μm, p < 0.001). The use of an MD may be a viable alternative to the ACTG because of its ability to provide increased keratinized tissue in comparison to the ACTG.

Objective: This study aims to evaluate periodontal clinical conditions after treatment for gingival recession (GR) using subepithelial connective tissue graft (SCTG) and acellular dermal matrix (ADM).Methods: Ten patients with Miller’s Class I and II recessions that had been treated with SCTG or ADM at the Periodontics Outpatient Department at Universitas Indonesia were selected for this study. The pre-operative data for GR, clinical attachment levels (CAL), and attached gingiva (AG) were retrieved from the patients’ medical records. The patients were recalled and the post-operative data were recorded.Results: The application of SCTG and ADM yields significant changes to GR, CAL, and AG levels. A comparison of two groups at the post-operative assessment stage showed no statistically significant differences, in terms of GR, CAL, and AG.Conclusion: SCTG and ADM yield similar outcomes in the treatment of GR. As such, ADM may be suggested as an alternative to SCTG for root coverage.

Abstract Aims “Gingival recession is a condition reported to occur due to abnormal periodontal anatomy, poor hygiene, excessive occlusal forces, toothbrush abrasion, and even iatrogenic or factitious causes. Though various surgical techniques are available to treat this problem, the most common is the palatal soft tissue autograft. Recently, an acellular dermal matrix allograft (ADMA) has been available as a substitute for the palatal tissue harvest. The aim of this study is to compare the ADMA with the conventional subepithelial connective tissue graft (SCTG) in the treatment of gingival recession.” Methods and Materials Fourteen patients with 20 gingival recessions of Miller's grade I and II were selected and randomized in two groups of control (SCTG) and test (ADMA). In each group ten recession defects were treated. The following parameters were measured at baseline and then at six months post surgery: recession height (RH), recession width (RW), probing depth (PD), attached gingiva (AG), keratinized gingiva (KG), and clinical attachment level (CAL). All parameters were analyzed using the two-sample t-test. Data analysis was performed using SPSS (version 11) software. Results The following mean changes (mm) occurred in SCTG and ADMA, respectively: 2.60±0.97 and 2.90±0.81 decrease in RH; 1.70±1.01 and 1.65±0.67 decrease in RW; 2.50±0.97 and 2.95±0.69 increase in KG; 2.25±0.92 and 2.65±0.85 increase in AG; 2.60±1.08 and 2.75±0.92 decrease in CAL; and finally 0.05±0.50 and 0.10±0.46 decrease in PD for the SCTG and ADMA groups, respectively. The percentage of root coverage for the two groups was 70.12%±22.81% and 72.08%±14.12%, respectively. The changes from baseline to the six-month visit were significant for both groups in terms of all parameters but PD. However, the differences in mean changes were not significant between the two groups in any of the parameters. Conclusion These findings imply the ADMA and SCTG techniques could produce the same results when used for the successful treatment of gingival recessions. In addition the ADMA could be used as an adequate alternative treatment modality for conventional techniques. Citation Rahmani ME, Lades MAR.
