RESUMO
BACKGROUND: Scaling and root planing is the gold standard non-surgical therapy in patients with periodontitis. However, mechanical debridement alone may not eradicate all periopathogens from subgingival niches. Adjunctive use of diode laser in pocket therapy may improve tissue healing by its bactericidal and detoxification effects in subgingival areas. The objective of this study was to evaluate and compare effectiveness of scaling and root planing alone and scaling and root planing along with diode laser in chronic periodontitis patients. METHODS: This is a prospective comparative study conducted in which 30 chronic periodontitis patients with at least one site with clinical attachment loss ?3mm in each contralateral quadrant were included and divided into Site A (control) scaling and root planing only and Site B (test) scaling and root planing with diode laser therapy. Clinical parameters (Plaque Index, Gingival Index, Probing Pocket Depth and Clinical Attachment Level) were recorded at baseline, one month and three months postoperatively and compared. Student's t-test was used to analyze intra and inter site mean variation. RESULTS: Site A and Site B showed significant improvements in clinical parameters at three months postoperatively (p ?0.05) with better improvement observed in Site B (p ?0.05). Conclusions: The use of diode laser as an adjunct to scaling and root planing can be considered as an effective treatment modality for the management of chronic periodontitis than scaling and root planing alone.
