Efficacy of mouthrinse spray in inhibiting cariogenic biofilm formation on toothbrush bristles|
Nascimento, Andresa Piacezzi; Faria, Gisele; Watanabe, Evandro & Ito, Izabel Yoko
The aim of this study was to evaluate the efficacy of Periogard®
(Colgate-Palmolive) and Plax® (Colgate-Palmolive) in inhibiting
biofilm formation of mutans streptococci (MS) on toothbrush bristles
used just once for 2 minutes with no dentifrice.
This study was performed into 3 phases in which mouthrinses and sterile
distilled water (control group) were sprayed 6 times (to standardize
the method) on toothbrush bristles used by 53 university students.
Toothbrushes were kept at room temperature for 3 hours and put
into test tubes each containing bacitracin sucrose broth (selective
enrichment for MS). After incubation at 37°C for 3 to 4 days, MS
biofilm on the bristles were analyzed and colony-forming units (CFU)
were counted by stereomicroscope under reflected light.
41 students completed the 3 phases of this study and 38 (92.7%)
control group toothbrushes had CFU of MS that varied from 1 to
uncountable. Periogard® and Plax® inhibited biofilm formation on the
bristles of 97.4% and 84.2% toothbrushes, respectively.
Periogard® and Plax®, in spray, reduced/eliminated biofilm formation
of MS on the toothbrush bristles. However, Periogard® was more
efficacious than Plax® for this purpose.
