RESUMEN

BACKGROUND: The study was aimed to assess and compare hard and soft tissue augmentation clinicoradiographically with and without advanced platelet-rich fibrin + (A-PRF+) block for the treatment of multiple gingival recession using vestibular incision subperiosteal tunnel access (VISTA). METHODS: A total of 24 patients, exhibiting multiple Miller's Class I or II recessions in the maxillary esthetic zone were included. Participants were divided into two groups, Group 1 was treated with VISTA & A-PRF+ block whereas Group 2 was with VISTA technique alone. Clinical parameters probing depth, width of keratinized gingiva, gingival biotype, recession depth, and clinical attachment level were recorded at baseline and the end of 6 months. The radiographic cone beam computed tomography measurements of labial plate thickness were taken at baseline and 6 months postoperatively. RESULTS: From baseline to 6 months both the groups showed a clinical and statistical improvement in the parameters. However, a statistically significant difference between the treatment modalities was not observed. In the inter-group comparison radiographically, labial plate thickness was statistically significant at the end of 6 months when compared to the baseline. CONCLUSION: A-PRF+ block along with the VISTA technique can be an alternative effective root coverage procedure for the management of multiple gingival recessions in the maxillary esthetic zone. KEY POINTS: Why is this study new information? To the best of our knowledge, this is the first study using advanced platelet-rich fibrin plus block for the treatment of multiple gingival recession with a thin labial plate. What are the keys to the successful management of these types of cases? Minimally invasive vestibular incision subperiosteal tunnel access technique, and avoidance of second surgical site morbidity are important factors for treatment and for patient compliance. What are the primary limitations of this study? Short study duration, small sample size, and no histological correlation can be considered as limitations of the study.

RESUMEN

Background: Several bone grafting formulations have been given clinically acceptable outcomes in treating intrabony defects. Platelet rich fibrin (PRF), an autologous platelet concentrate holds potential to be used for regenerative treatment. The purpose of this study was to evaluate clinical and radiographic outcomes in periodontal intrabony defects treated with advanced-PRF block (A PRF + i PRF + nanohydroxyapatite [nHA]) compared to nHA alone. Methods: Twenty-eight sites in chronic periodontitis patients having probing pocket depth (PPD) ≥6 mm and 3 walled intrabony defects (depth of ≥3 mm) were selected, randomly allotted into two groups: Group A was treated with A-PRF block and Group B with nHA (Sybograf™). Clinical parameters including plaque index (PI), gingival index (GI), PPD, relative attachment level (RAL) and radiographically linear and volumetric defect fill were assessed using cone beam computed tomography at baseline and 6 months postoperatively. Results: Intragroup comparison using paired t-test and intergroup comparison using unpaired t-test was done. Group A demonstrated significantly higher reduction in PPD and gain in RAL when compared to Group B (P ≤ 0.05) at the end of 6 months. Similarly gain in bone volume was greater in Group A (0.1 ± 0.05) as compared to Group B (0.04 ± 0.02) (P ≤ 0.05). Conclusion: Advanced-PRF block showed significant clinical and radiographic improvement as compared to nHA alone which depicts that, it may be an ideal graft to be used for the treatment of periodontal intrabony defects.
