AI Article Synopsis
- - The study investigates the modified apically repositioned flap (MARF) technique, which can result in discomfort due to exposed periosteum and potential bone loss, and proposes using platelet-rich fibrin (PRF) to enhance healing.
- - In a trial with 10 patients, one group received the MARF plus PRF treatment while the control group only received MARF; both groups showed increased attached gingiva, but the PRF group experienced better outcomes.
- - Results indicated that the PRF group had a greater increase in gingival width and thickness, less wound shrinkage, and similar postoperative pain compared to the MARF-only group, suggesting that PRF can improve the MARF technique’s effectiveness.
Article Abstract
Objectives: One of the simplest methods to increase keratinized gingiva is the modified apically repositioned flap (MARF) technique. In this method, the periosteum remains exposed, which may lead to postoperative pain and discomfort. In the presence of bone dehiscence, bone resorption and gingival recession may occur. Hence, this study aims to use platelet-rich fibrin (PRF) to promote wound healing in the MARF technique and overcome its disadvantages.
Material And Methods: In this randomized controlled trial study, 10 patients (six males and four females with a mean age of 33.9 ± 11.13) with less than 2 mm of attached gingiva bilaterally were treated by the MARF + PRF membrane (test group), on the one hand, whereas, on the other hand, it was treated only by MARF (control group). Clinical parameters of keratinized gingiva include thickness, width, and vestibule depth before and 8 weeks after the intervention were measured.
Results: The attached gingival width increased significantly in both groups (1.7 mm in the MARF and 2.3 mm in the PRF) and this was greater in the PRF group (p < .05). Gingival thickness in the PRF method was significantly higher than in the control group (p < .05). Probe depth, vestibular depth, and postoperative pain were not different in both groups. Wound shrinkage in the MARF group (51%) was significantly higher than in the PRF group (30%) (p < .05).
Conclusion: Using PRF with the MARF method significantly increased the width and thickness of the gingiva and reduced shrinkage compared to MARF only. Postoperative pain and vestibular depth changes were similar in both groups.

: This study aimed to evaluate the role of A-PRF (advanced platelet-rich fibrin) in the enhancement of wound healing and protecting the periodontal health of mandibular second molars after the extraction of mandibular third molars. Additionally, the study assessed the levels of pro-inflammatory cytokines in the gingival crevicular fluid (GCF) of mandibular second molars as markers of inflammation. : Twenty-five systemically healthy adult patients with bilateral removal of impacted mandibular third molars were included.

The objective of this study was to compare single-needle arthrocentesis with the conventional two-needle arthrocentesis, as well as the additional intracapsular injection of hyaluronic acid or platelet-rich fibrin. A total of 96 patients with established osteoarthritis (OA) ( = 48) or with internal de-arrangement (DD) ( = 48) were assigned single-needle arthrocentesis with distension of the joint or conventional two-needle arthrocentesis with or without intracapsular injection of the medication (hyaluronic acid (HA) or platelet-rich plasma (PRP)) performed every month over a period of 6 months. The maximum mouth opening and pain, as measured by the visual analog scale (VAS), were compared.

Dental implants are essential for the prosthetic rehabilitation of edentulous patients, requiring adequate bone volume and density for osseointegration and load support. The posterior region of the maxilla, commonly deficient in bone quality and quantity, represents a clinical challenge. This case series reports an analysis involving 69 dental implants in the atrophic maxilla of nine patients.

Article Synopsis
- A systematic review and meta-analysis were conducted to assess the impact of platelet-rich fibrin (PRF) on the secondary stability of delayed dental implants, as prior research on this topic was insufficient.
- Twelve trials involving 456 dental implants were analyzed, revealing that while PRF may improve stability at different time points, the certainty of evidence remains low due to varying biases in the studies.
- The findings suggest that more high-quality randomized controlled trials with longer follow-up periods are necessary to provide clearer guidance for clinicians regarding the use of PRF in delayed dental implant placements.
