Context: Different techniques are used for periodontal therapy, viz. scaling and root planing, subgingival curettage, gingivectomy, and full- or split-thickness flap procedures with or without osseous recontouring. Most of the said periodontal surgeries are invasive and associated with pain and secondary discomfort, thus leading to a quest for newer techniques such as laser-assisted closed pocket debridement techniques for periodontal therapy. The present study was designed to compare the efficacy of closed pocket debridement with diode laser and periodontal open flap debridement as assessed by clinical and microbiological parameters. Materials and Methods: Twenty patients in an age range of 20–54 years and with pocket depth of ≥5 mm and ≤7 mm were included in the study. The plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment level (CAL), and colony forming units (CFUs) of the periodontal pathogens namely Porphyromonas gingivalis, Fusobacterium nucleatum, Aggregatibacter actinomycetemcomitans, and streptococci were compared in patients undergoing closed pocket debridement with diode laser (Group I) against open flap debridement (Group II) at baseline and after 3 months of the procedure. Results: There was a statistically significant difference between the PD reduction in Group I and Group II (P = 0.02), with Group II showing greater reduction in PD. Furthermore, the mean value of CFUs after 3 months of the procedures in Group I was significantly less as compared to Group II. Conclusion: The laser-treated group (Group I) was found to be better in terms of decrease in clinical PD as compared to Group II. The bactericidal effect of the diode laser was, also, clearly evident by a greater reduction of CFUs of periodontal pathogens in Group I as compared to Group II.
