Abstract
Background: Chemo-mechanical treatment concepts have been developed to improve the outcome of non-surgical periodontal therapy. Recently, the clinical additive value of a supersaturated chlorhexidine varnish was shown when used as an adjunct to staged scaling and root planing. The aim of this study was to investigate the clinical effects of a treatment strategy for chronic periodontitis based on a combination of same-day full-mouth root planing and subgingival chlorhexidine varnish administration. Methods: A randomized, controlled, single-blind, parallel trial was conducted on 33 non-smoking chronic periodontitis patients. The control group received oral hygiene instructions and same-day full-mouth root planing. The test group received the same instructions and treatment; however, all pockets were disinfected using a chlorhexidine varnish. Clinical response parameters were recorded at baseline and after 1, 3, and 6 months. Results: Both groups showed significant reductions in probing depth following therapy (P < 0.001). There was no significant difference in full-mouth probing depth between the groups at any examination point. However, when a site-specific comparison was made, additive effects were found in the test group; an extra pocket reduction of 0.93 mm (P = 0.044) for initially deep pockets ( >= 7 mm) was found at study termination. Additive clinical attachment gains seemed to be temporary. Impermanent extra pocket reductions and clinical attachment gains were found for initially medium-deep pockets (4 to 6 mm). Conclusion: The outcome of same-day full-mouth root planing may benefit from the subgingival administration of a highly concentrated chlorhexidine varnish, at least in terms of pocket reduction in initially deep sites ( >= 7 mm)Keywords
