Objective: This study aimed to compare the clinical efficacy, aesthetic outcomes, and perceived pain levels of current subgingival debridement methods used in the treatment of Stage I-II periodontitis. Materials and Methods: Ninety patients (52 females, 38 males) diagnosed with mild to moderate periodontitis (Stage I–II) were randomly assigned to one of three treatment groups: Conventional Therapy (CT), involving Gracey curettes and sonic scalers followed polishing; Guided Biofilm Therapy (GBT); and Plaque-Disclosed Conventional Therapy (PDCT).
Each patient received non-surgical periodontal treatment with the goal of achieving periodontal health (defined as probing depth 0.05). All three methods were comparably effective in achieving the desired periodontal health status. There were no statistically significant differences in pain perception among the groups during treatment.
Conclusion: Current non-surgical periodontal treatment methods provide similar clinical outcomes in the management of mild-moderate periodontitis when monitored over 6 months. GBT may be preferred for patients with greater aesthetic concerns. The use of plaque disclosing agents to visualize biofilm appears to offer advantages during therapy.
