Can anti-erosion dentifrices also provide effective plaque control?

چکیده
OBJECTIVE While gingivitis and caries continue to be prevalent issues, there is growing concern about dental erosion induced by dietary acids. An oral hygiene product that protects against all these conditions would be beneficial. This study investigated the potential of two anti-erosion dentifrices to inhibit plaque. METHODS This was a randomized, three-period, two-treatment, double-blind, crossover study evaluating a stannous chloride/sodium fluoride dentifrice (SnCl(2)/NaF, blend-a-med(®) Pro Expert) and a popular anti-erosion dentifrice (NaF, Sensodyne(®) ProNamel(™)). During Period 3, subjects were randomized to repeat one treatment to evaluate any product carryover effects. Each treatment period was 17 days. Test dentifrices were used with a standard manual toothbrush. Digital plaque image analysis (DPIA) was employed at the end of each period to evaluate plaque levels (i) overnight (am prebrush); (ii) post-brushing with the test product (am post-brush); and (iii) mid-afternoon (pm). Analysis was conducted via an objective computer algorithm, which calculated total area of visible plaque. RESULTS Twenty-seven subjects completed the study. At all time points, subjects had statistically significantly (P ≤ 0.0001) lower plaque levels after using the SnCl(2)/NaF dentifrice than the NaF dentifrice. The antiplaque benefit for the SnCl(2)/NaF dentifrice versus the NaF dentifrice was: am prebrush = 26.0%; am post-brushing = 27.9%; pm = 25.7%. CONCLUSIONS The SnCl(2)/NaF dentifrice provided significantly greater daytime and overnight plaque inhibition than the NaF toothpaste. When recommending dentifrice to patients susceptible to dental erosion, clinicians can consider one that also inhibits plaque.

Randomized controlled trial to study plaque inhibition in calcium sodium phosphosilicate dentifrices.
OBJECTIVES To evaluate the effect of three calcium sodium phosphosilicate (CSPS)/sodium monofluorophosphate containing dentifrices, compared to positive and negative controls on plaque re-growth in a non-brushing model, after 4 days of twice daily use, as determined by plaque area and Turesky plaque index (TPI).

متن کاملEffects of a Novel Dental Gel on Enamel Surface Recovery from Acid Challenge
BACKGROUND Objective was to evaluate the in vivo effects of a novel dental gel (Livionex gelR) vs. a comparison dental gel on the surfaces of pre-eroded enamel chips. METHODS On days 1-5, after toothbrushing with dentifrice, nine subjects each wore 8 enamel chips mounted on a palatal appliance for 4 h. Enamel blocks were pre-demineralized daily. After 2 day washout, subjects repeated the prot...

Background and Objectives Herbal dentifrices are fast gaining popularity in most parts of Asia and Europe. Although effects of dentifrices on pathogenic plaque microorganisms has been documented, little or no evidence exists with regard to their effects on the useful microflora, which help to keep the pathogenic strains at bay. The present study was attempted to evaluate and compare these effec...
