Methods: Twenty-six subjects with probing depth ≥5 mm and bleeding on probing participated in a split-mouth trial. At baseline, the patients received full-mouth scaling and root planing followed by placement of chlorhexidine chips. Test sites still ≥5 mm deep at 3 and 6 months were retreated with another chlorhexidine chip.
Results: Improvements of bleeding scores, probing depths and clinical attachment levels were observed for both test and control sites at 6 weeks compared to baseline. No differences in improvements were found comparing test and control sites.
Conclusions: This study did not observe any significant adjunctive effect of subgingival placement of chlorhexidine chips after scaling and root planing.
