Platelet Rich Fibrin in double lateral sliding bridge flap procedure for gingival recession coverage: An original study

Background: Gingival recession is a common occurrence in periodontal disease leading to an unaesthetic appearance of the gingiva. The effect of platelet-rich fibrin (PRF), when used along with double lateral sliding bridge flap (DLSBF), remains unknown. The aim of this study is to evaluate the effect of PRF in conjunction with DLSBF for multiple gingival recessions. Materials and Methods: Twenty systemically healthy individuals exhibiting Grade II gingival recession on their mandibular central incisors were recruited in this study. These patients were randomly assigned into two groups: DLSBF and PRF + DLSBF. The clinical parameters that were evaluated in this study were gingiva recession height, gingiva recession width, width of keratinized gingiva, clinical attachment level, and probing depth. PRF was procured from the patient's blood at the time of the surgery and used for the procedure. The follow-up was performed at 12 and 24 weeks postsurgery. Results: Statistically significant difference was observed between the clinical parameters at baseline and 12 and 24 weeks within the groups. There was no statistically significant difference, between the groups. Mean root coverage (RC) was 80% ±29.1% in the DLSBF group and 78.8% ±37.6% in the DLSBF + PRF group with no statistically significant difference. Conclusion: From the results obtained in this study, the addition of PRF to DLSBF gives no additional benefits to the clinical parameters measured in RC

Anesthetic efficacy of 4% articaine and 2% lignocaine in achieving palatal anesthesia following a single buccal infiltration during periodontal therapy: A randomized double-blind split-mouth study

Background: The aim of this randomized split-mouth double-blind study was to evaluate whether 4% articaine hydrochloride with 1:100,000 epinephrine administered as a single buccal infiltration in the maxillary posterior sextant can provide palatal anesthesia when compared with 2% lignocaine with 1:100,000 epinephrine during scaling and root planing and access flap surgery (AFS). Material and Methods: A total of 40 patients with chronic generalized periodontitis requiring periodontal therapy in the maxillary posterior sextants were recruited in this study. About 4% articaine and 2% lignocaine were administered as buccal infiltration in a split-mouth design randomly. The pain scores in the palatal aspect were recorded during scaling and root planing and open flap debridement using Heft-Parker visual analog scale. The onset of anesthesia was also recorded and compared. Results: The success rate for maxillary buccal infiltration to induce palatal anesthesia using articaine was 90% during scaling and root planing and 82.5% during AFS and for lignocaine solution was 20% and 15%, respectively. The difference between the two agents was statistically significant (P < 0.05). The onset of anesthesia between articaine and lignocaine was also found to be statistically significant (P < 0.05). Conclusion: In this study, we observed that the efficacy of 4% articaine was superior to 2% lignocaine to induce palatal anesthesia following maxillary buccal infiltration in maxillary posterior sextants
