Propolis extract as an adjuvant to periodontal treatment.

Purpose: The aim of this study was to evaluate the effect of subgingival irrigation with propolis extract by clinical and microbiological parameters.

Materials And Methods: Twenty patients diagnosed with chronic periodontitis presenting three non-adjacent teeth with deep pockets were selected. After scaling and root planing, the selected periodontal sites were submitted to one of the following treatments: irrigation with a hydro alcoholic solution of propolis extract twice/week for two weeks (group A); irrigation with a placebo twice/week for two weeks (group B); or no additional treatment (C).
