Abstract
Introduction: Periodontitis is an inflammatory disease of the periodontium. The most commonly used treatment modality involves scaling and root planing. However, complete removal of bacterial deposits is not always possible. Thus, adjunctive therapeutic strategies like systemic antibiotics and laser therapy have evolved.
Objective: To evaluate the clinical effect of diode laser compared to systemic antibiotics in the treatment of chronic periodontitis.
Methods: A non-randomised clinical trial was conducted in the department of Periodontics and Oral Implantology, People’s Dental College and Hospital from 2022 April to 2023 March after ethical approval. Thirty-two patients with chronic periodontitis were assigned into two groups using convenience sampling. Group A received diode laser (980 nm) applications, and Group B received adjunctive systemic Amoxicillin 500 mg three times daily and Metronidazole 400 mg three times daily for seven days. Clinical parameters: probing depth, clinical attachment level, plaque index, and gingival index were evaluated at one month, three months, and six months post-treatment. Data were analysed in SPSS v.20.
Results: Mean values of probing depth, clinical attachment level, plaque index, and gingival index reduced significantly after treatment in both treatment groups, with more clinical improvement in the diode laser group. However, for the intergroup comparison, the clinical parameters were not significant.
Conclusions: The findings of the current study showed significant improvement in all clinical parameters as compared with baseline in both treatment groups. However, no significant differences between the treatment modalities were found regarding an increase in periodontal probing depth and clinical attachment level.
