0.1%/0.2% commercial chlorhexidine solutions as subgingival irrigants in chronic periodontitis
The aim of this study was to compare the effects of two common British chlorhexidine solutions in a subgingival irrigation system, as adjuncts in the treatment of chronic adult periodontitis. Eight men and 11 women used either Corsodylor (0.2% CH) or Eludril (0.1% CH) for 28 days with a Max-I-Probe delivery system applied twice daily. Gingival and bleeding indices were established as well as probing pocket depth and probing attachment levels. No control, such as distilled water, was used as an irrigant. Improvements with both concentrations of chlorhexidine were demonstrated to occur equally by days 28 through 84 as shown by reduction in loss of attachment and reduction in pocket depth.
This study has limitations such as small population size, single-blinded design, and no control. Thus it falls into the category of a pilot study, suggesting that local irrigation with either a 0.1% or 0.2% chlorhexidine solution used twice daily for a duration of four weeks might be of benefit to patients with chronic moderate periodontitis.
