AI Article Synopsis

  • * Measurements of MGL, keratinized and attached gingiva width, and clinical attachment were taken at 3, 6, and 12 months post-surgery in 19 patients with Miller class I or II defects.
  • * Results showed the MGL shifted upward during surgery but moved back down closer to its initial position after a year, while there was a notable increase in the width of keratinized and attached gingiva.

Article Abstract

Aim And Objective: The aim of this study is to evaluate the positional changes that occur in mucogingival line following the use of subepithelial connective tissue graft (SCTG).

Materials And Methods: In 19 Miller class I or II gingival recession defects, distance between mucogingival line (MGL) and cemento-enamel junction, also width of keratinized and attached gingiva, and clinical attachment level were measured. SCTG were used for covering the exposed roots. A fore mentioned parameters were repeated at 3, 6 and 12 months after surgery and alterations were measured. Paired t test was used to analyze the results.

Results: MGL had been moved in coronal direction (4.39 +/- 0.77 mm on average) during surgical approach. After 1 year, MGL shifted 2.11 +/- 0.7 mm apically. In accordance with this apical shift, a significant increase in the width of keratinized and attached gingival width (2.89 +/- 0.63 mm and 2.82 +/- 0.5 mm, respectively) was seen (P < 0.05).

Conclusion: MGL tended to revert back to its original position following the use of SCTG, and this reversion is accompanied with an increase in the keratinized and attached gingival width.

This study aimed to investigate factors that influence the 12-month outcomes after the treatment of multiple gingival recessions (GRs) with a modified coronally advanced tunnel (MCAT) and a subepithelial connective tissue graft (SCTG), with cross-linked hyaluronic acid (HA, tests) or without (controls). : Twenty-four patients with 266 GRs were treated. A logistic regression model was set to identify the baseline parameters that could predict the 12-month outcomes.

Objectives: To assess the differences between adjunctive therapy with Concentrated Growth Factor (CGF), Platelet-rich Fibrin (PRF) membranes, and available control groups in the clinical outcomes of root coverage.

Materials And Methods: Randomized controlled clinical trials (RCTs) were identified in Pubmed/Medline, Scopus, and ISI Web of Science databases to assess the treatments after 6 months using a Bayesian random-effect network meta-analysis (NMA) framework regarding reduction in pocket depth (PD), clinical attachment loss (CAL), recession depth (RD), and width (RW), as well as, keratinized tissue width (KTW) and thickness (KTT) gain, and complete (CRC) and mean (MRC) root coverage percentages.

Results: Thirty-two RCTs were included, from which 27, 18, 12, eight, one, and one studies investigated PRF, connective tissue graft (CTG), flap alone, CGF, enamel matrix derivative (EMD), and dehydrated amniotic membrane, respectively.

Assessing the effectiveness of advanced platelet rich fibrin in treating gingival recession: a systematic review and meta-analysis.

BMC Oral Health

Oral Medicine, Periodontology, Diagnosis and Oral Radiology Department, Faculty of Dentistry, Mansoura University, Mansoura, 33516, Egypt.

Objectives: The literature lacks comprehensive evidence on the efficacy of advanced platelet rich fibrin(A-PRF) in treating gingival recession. Therefore, this systematic review and meta-analysis aimed to evaluate the effectiveness of A-PRF in the treatment of gingival recession.

Materials And Methods: We adhered to the guidelines of PRISMA in searching the following databases: PubMed/MEDLINE, Embase, Cochrane Library, Web of Science, and Scopus to include all the eligible studies according to the prespecified inclusion and exclusion criteria.

Primary simple conjunctival cysts are congenital, non-neoplastic, fluid-filled lesions lined by non-keratinizing squamous epithelium without dermal appendages. They are usually located in the anterior superonasal or superotemporal orbit and are typically managed with complete surgical excision.

Background: Drug-induced gingival enlargement (DIGE) is a common side effect of medications such as anticonvulsants, calcium channel blockers, and immunosuppressants. The treatment of choice for the condition is drug withdrawal or substitution in combination with the nonsurgical phase. In some cases, additional internal or external bevel gingivectomy is needed to achieve periodontal health.
