Evaluating the Effect of Diode Laser as an Adjunct to Open Flap Debridement in Association with Photobiostimulation with 970nm Diode Laser in Treatment of Chronic Periodontitis: A Randomized Clinical Trial

Abstract

Background: To evaluate the effect of diode laser as an adjunct to open flap debridement in association with photo bio-stimulation with 970nm diode laser in the treatment of chronic periodontitis.

Material and Methods: Five subjects aged 25 - 55 years with moderate to severe chronic periodontitis, who required periodontal flap surgery, were randomized and included in this study. The present study is a prospective comparative study. It is categorized under a randomized control trial.  All the subjects with 20 sites were randomly divided into 4 groups, which are as follows: Group I consisted of 5 sites for conventional flap surgery, Group II consisted of 5 sites for conventional flap surgery and laser, Group III consisted of 5 sites for conventional flap surgery along with laser and biostimulation, Group IV consisted of 5 sites for conventional flap surgery with biostimulation. The assessment of clinical parameters,probing pocket depth (PPD), clinical attachment loss (CAL), and visual analog scale (VAS) was evaluated at 3 months.

Result: The results of this study demonstrated a statistically significant improvement in clinical parameters such as probing pocket depth (PPD) reduction, clinical attachment level (CAL) gain, and reduced bleeding on probing (BOP) in the test group (OFD + 970 nm diode laser + PBM) compared to the control group (OFD alone). These findings support the adjunctive use of diode lasers in enhancing the clinical efficacy of periodontal therapy.

Conclusion: The adjunctive use of 970nm diode laser in combination with photo-biostimulation contributed to improved tissue repair and reduced postoperative inflammation.
