Long-term effect of the combined use of powered toothbrush and triclosan dentifrice in periodontal maintenance patients
: Blackwell Synergy
Aim: To test the hypothesis of a superior clinical and microbiological effect of the
combined use of powered toothbrush1triclosan-containing dentifrice compared with
manual toothbrush1regular fluoride-containing dentifrice in periodontal maintenance
Material and Methods: A total of 128 periodontitis subjects involved in recall
programmes were randomized to use either powered toothbrush with triclosandentifrice
(test) or manual toothbrush and standard dentifrice (control). Supportive
periodontal treatment was provided at baseline and every 6 months. Plaque, bleeding
on probing (BoP), probing pocket depth (PPD) and relative attachment level (RAL)
were scored at baseline, 1, 2 and 3 years. Subgingival plaque samples were taken and
analysed for their content of 40 bacterial species at each examination interval. All
analyses were performed by Ã¢â‚¬ËœÃ¢â‚¬Ëœintention-to-treatÃ¢â‚¬â„¢Ã¢â‚¬â„¢ protocol.
Results: Both groups showed significant reduction in BoP, PPD and in mean total
counts of the 40 bacterial species between baseline and 3 years, while plaque score and
RAL remained almost unchanged. No significant differences between the two
prevention programmes were found for any of the clinical outcome variables or
in mean counts of the various bacterial species.
Conclusions: The study failed to demonstrate superior clinical and microbiological
effects of powered toothbrush1triclosan dentifrice compared with manual
toothbrush1standard fluoride-dentifrice in periodontitis-susceptible patients on
regular maintenance therapy.
