Statement Of The Problem: Recently allogenic mesenchymal stem cells are proposed to have multipotential progenitor cell capabilities to differentiate into cementoblasts, osteoblasts, and periodontal ligament fibroblasts.
Purpose: The aim of the present study was to compare the efficacy of human umbilical stem cells cultured on polylactic acid (PLA), polyglycolic acid (PGA) membrane with PLA/PGA membrane alone in the treatment of multiple gingival recession defects.
Materials And Method: A total number of 14 cases of multiple gingival recession (Miller's Class I or II) located in the anterior region were randomly selected and divided into test (stem cells in combination with PLA/PGA membrane) and control group (PLA/PGA membrane alone). Clinical parameters including gingival recession, probing pocket depth, clinical attachment level, and width of keratinized gingiva were recorded at baseline, and at 6 months postoperative.
Results: At baseline, there was 2.28 mm and 2.14mm mean gingival recession at 16 sites and 14 sites in test and control groups respectively. At 6 months post-surgery, test group showed 1.57 mm mean reduction of gingival recession indicating 66% root coverage, while the control group showed 1.24mm mean reduction of gingival recession indicating 57% root coverage.
Conclusion: In the present study, the stem cell with PLA/PGA membrane showed significantly higher mean root coverage compared to only PLA/PGA membrane group.

Objectives: The purpose of this study was to propose a new difficulty score for the treatment of multiple gingival recessions (GRs) with Modified Coronally Advanced Tunnel (MCAT), and to test the score's reliability.
Material And Methods: A difficulty score was developed for the assessment and grading of 13 relevant anatomical parameters at baseline. Six experienced dental practitioners evaluated existing GRs in three patients.

Objective: To compare the influence of different emergence profile of implants in mandibular molar on the peri-implant soft tissue.
Methods: Forty-four implants were divided into two equal groups by mucosal thickness, ≥2 mm (group A) or < 2 mm (group B), and were randomly included in the test group and the control group. In the control group, the patients were treated by a prosthesis with no transmucosal modifications (subgroups A1 and B1).

Orthodontic treatment aims to correct malocclusions and ensure the overall health and stability of the periodontium. The relationship between orthodontic therapy and periodontal health is intricate and multifaceted, and a comprehensive approach is often required to achieve optimal outcomes. Firstly, this article delves into the impact of orthodontic mechanics on periodontal tissues, emphasizing the importance of minimizing iatrogenic effects such as root resorption and gingival recession.

Insufficient keratinized mucosa is a common clinical problem. Although there is no consistent data on the long-term success of implant restorations relative to the presence or absence of peri-implant keratinized mucosa, it is widely accepted that the presence of keratinized mucosa width<2 mm is associated with increased biofilm accumulation, soft-tissue inflammation, and mucosal recession. Free gingival graft (FGG) is the standard surgical intervention for augmenting the width of keratinized gingiva.

Background: Injectable platelet-rich fibrin (i-PRF) has the capacity to release great amounts of several growth factors, as well as to stimulate increased fibroblast migration and the expression of collagen, transforming growth factor β, and platelet-derived growth factor. Consequently, i-PRF can be used as a bioactive agent to promote periodontal tissue regeneration.
Objective: We aim to compare and evaluate the effectiveness of i-PRF in periodontal tissue regeneration.
