RESUMO
This study was conducted to evaluate the effects of platelet-rich fibrin (PRF) on palatal wound healing after free gingival graft (FGG) harvesting. A total of 125 patients were randomized after FGG: PRF with butyl-cyanoacrylate (BC) adhesive (PRF group; n = 42), BC adhesive alone (BC group; n = 42), and sterile wet gauze compression (WG group; n = 41). Bleeding, pain, epithelialization, feeding habits, and sensation scores were recorded for different time points. Statistically significant differences were found for all parameters in favor of the PRF group (P = .0001). PRF may provide significant benefits for wound healing parameters and patients' postoperative course after palatal graft harvesting.

The aim of this study was to evaluate the laterally moved coronally advanced flap (LMCAF) technique in which magnified vision was used in conjunction with microsurgical instruments (LMCAF-M), and to compare the results with conventional LMCAF technique (LMCAF-C) in Miller Class III isolated recession-type defects. A total of 50 patients with recessions located at incisors and canines were treated with LMCAF-M or LMCAF-C. Outcome parameters (complete root coverage [CRC] and mean root coverage [MRC]) were assessed 6 months postoperatively. Of the 25 defects in each group, 13 in the LMCAF-M (92.0%) and 17 in the LMCAF-C group (68.0%) exhibited CRC (P < .007). MRC scores were 90.48% for the LMCAF-C group and 97.64% for the LMCAF-M group (P < .04). Patient satisfaction with esthetics and postoperative morbidity were better in the LMCAF-M group (P < .032). This study indicates that performing LMCAF with microsurgical instruments offers definite advantages in terms of CRC and MRC, decreased postoperative morbidity, and increased acceptance by patients.
