Effect of diode laser-assisted flap surgery on postoperative healing and clinical parameters: A randomized controlled clinical trial

Abstract

Background and Objectives:Lasers have been widely used because of several potential benefits such as antibacterial effect and stimulation of wound healing. In addition, lasers help in hemostasis and delaying epithelial migration which may facilitate the outcome of flap surgery. Hence, this study is aimed to investigate the adjunctive effect of diode laser irradiation on conventional access flap surgery in the treatment of periodontal disease.Materials and Methods:A total of 23 patients requiring periodontal flap surgery in two sextants with probing pocket depth ≥5 mm in at least three teeth post-phase I therapy were selected for a split-mouth study. Flap surgery with adjunctive diode laser irradiation was performed in the test quadrant while conventional access flap surgery was done in the control quadrant. Procedural pain and tissue response of the patients were evaluated at 3, 7, and 14 days postoperatively. Clinical parameters including probing depth, clinical attachment level, plaque index, and gingival index were recorded at baseline, 3 months, and 6 months following treatment.Results:There is no significant difference between the groups with respect to healing response of tissues; however, patients experienced more pain in test sites compared to control sites. Intragroup comparisons showed a statistically significant reduction of all clinical parameters from baseline to 6 months without any significant difference between the groups.Conclusion:Overall within the limitations of the study, diode lasers did not show any significant added benefits over conventional access flap surgery.

Comparative evaluation of the efficacy of diode laser as an adjunct to modified Widman flap surgery for the treatment of chronic periodontitis: A randomized split-mouth clinical trial

“…Our study showed an insignificant reduction in gingival inflammation for both the groups from baseline. Similar results were reported by Jonnalagadda et al [ 28 ] The decrease in GI can be attributed to the effective removal of calculus and diseased granulation tissue leading to reduction in gingival inflammation.…”

“…However, there are insufficient evidences to support the adjunctive use of diode laser in periodontal flap surgery. [ 28 29 30 31 32 ] Hence, this study was designed to evaluate the same.…”

Clinical and microbiological evaluation of 940-nm diode laser as an adjunct to modified Widman flap for the management of chronic periodontitis: A 6-month randomized split-mouth clinical trial

“…A recent study reported no additional advantages for DL with conventional access flap debridement than periodontal flap alone. 19 Moreover, Lobo and Pol 20 reported more gingival inflammation reduction in DL associated with flap surgery than flap surgery alone; however, their study did not show any difference in PPD and CAL in the intergroup comparison.…”

Patient-reported outcomes of laser-assisted pain control following non-surgical and surgical periodontal therapy: A systematic review and meta-analysis

“…During the first stage, 104 studies were excluded based on the evaluation of titles and abstracts (inter-reviewer agreement, kappa statistic = 0.92). Second, after screening the full-text articles of the remaining 23 studies, 13 studies were excluded because of inappropriate study design [15][16][17][18][19][20] and irrelevant outcome measurement [21][22][23][24][25][26][27] (S1 Table) and 10 eligible studies [28][29][30][31][32][33][34][35][36][37] (five for HLLT, four for PBMT, and one for both HLLT and PBMT) were included in this systematic review (interreviewer agreement, kappa statistic = 0.91). Of these, four studies [29,31,33,34], which showed adequate continuous data concerning the pain level measured with VAS score, were included in the meta-analysis.…”
