Antibacterial Effects of a Novel Stannous Fluoride Toothpaste Stabilized With Nitrate and Phosphates (SNaP): In Vitro...

Area of Science:

• Oral microbiology
• Dental formulations
• Antimicrobial agents

Background:

• Stannous fluoride (SnF2) is a known antimicrobial agent in oral care but has historically faced stabilization challenges.
• A new formulation, SNaP (stannous fluoride stabilized with nitrate and phosphates), offers prolonged therapeutic benefits without compromising product aesthetics.
• This innovation addresses previous limitations in SnF2 stability for toothpaste applications.

Purpose of the Study:

• To evaluate the in vitro and in vivo antibacterial performance of the novel SNaP toothpaste.
• To compare the efficacy of SNaP toothpaste against control toothpastes and no treatment.
• To assess the sustained antibacterial effect of SNaP toothpaste on various oral microenvironments.

Main Methods:

• In vitro assessment of dentifrice antibacterial activity using bacterial bioenergetics (oxygen consumption, extracellular acidification).
• A double-blind, randomized, controlled clinical trial with 98 subjects using SNaP toothpaste or a non-antibacterial control.
• Analysis of bacterial load in plaque, tongue, cheek, gum, and saliva at baseline, 2, and 4 weeks post-treatment.

Main Results:

• SNaP toothpaste significantly suppressed bacterial respiration and glycolysis in vitro biofilms compared to controls.
• Clinical trial showed significantly lower bacterial loads in all oral sites 12 hours post-brushing with SNaP toothpaste after 2 and 4 weeks.
• SNaP toothpaste demonstrated significant reductions in bacterial counts from baseline in multiple oral microenvironments by week 4.

Conclusions:

• The SNaP formulation provides superior and sustained antibacterial activity compared to other tested toothpastes.
• Stabilized stannous ions in SNaP toothpaste are crucial for its enhanced antibacterial performance.
• SNaP toothpaste offers potential benefits for oral hygiene, including reduced risk of decay, gum disease, calculus, and halitosis.
