Impact of supragingival scaling on the outcomes of subgingival instrumentation completed after 1 week: a split-mouth randomized clinical trial.

Objective: To investigate the impact of supragingival scaling on the clinical outcomes of subgingival instrumentation completed after 1 week.

Method And Materials: In 27 patients with Stage II and Stage III periodontitis, pairs of contralateral quadrants were randomly assigned into test group 1 (single sitting scaling and root planing) and test group 2 (supragingival scaling followed by subgingival instrumentation after 1 week). Periodontal parameters were recorded at baseline, 2, 4, and 6 months; Gingival crevicular fluid vascular endothelial growth factor (VEGF) estimation was done at baseline in both groups and 7 days after supragingival scaling in test group 2.
