In 1976, a three-year study was started in Biddeford, Maine, a non-F city, to compare the cariostatic effect of weekly use of a 0.2~ NaF rinse with daily use of a 0.05~ NaF rinse in a public health program. Participants in grades 5-7 (ages 10-12) in public and parochial schools were randomly assigned to the weekly F rinse, daily F rinse or control group that rinsed weekly with a placebo solutio...

More and more scientific evidence show that fluorides have a cariostatic action to the plaque-saliva-tooth interface during cariogenous dissolution. Fluorides slow down demineralization and enhance remineralization. Their action is optimal, in the oral environment, when used at low concentrations on a continuous basis. The use of the fluorinated toothpastes during brushing of the teeth is a sim...

BACKGROUND Propolis is a natural resinous mixture produced by honeybees, which exhibits anti-microbial, anti-inflammatory, cytostatic and cariostatic properties. The aim of the study was to evaluate the anti-bacterial efficacy of a propolis based dentifrice on Mutans Streptococci colonizing the oral cavity of young patients using Dentocult® SM strip mutans test. METHODS Screening of 367 male ...

Studies have shown the cariostatic effect of Er,Cr:YSGG (2.78 mm) laser irradiation on human enamel and have suggested its use on caries prevention. However there are still no reports on the intrapulpal temperature increase during enamel irradiation using parameters for caries prevention. The aim of this in vitro study was to evaluate the temperature variation in the pulp chamber during human e...

OBJECTIVES Laser irradiation has been suggested as an adjunct to traditional caries prevention methods. But little is known about the cariostatic effect of diode laser and most studies available are on permanent teeth.The purpose of the present study was to investigate the effect of diode laser irradiation combined with topical fluoride on enamel surface microhardness. MATERIALS AND METHODS F...

This study investigated fluoride release, acid resistance and shear bond strength (SBS) of new 4-META/MMA-TBB-based fluoride-containing resin adhesive (Super-Bond/F3). Super-Bond, Transbond Plus and Fuji Ortho LC were selected for comparison. Fluoride release into distilled water during 6-month period was measured using disk-shaped specimens. Brackets were bonded to human premolars with each ma...

The low concentration of available calcium (Ca) in oral fluids limits the formation of Ca-mediated fluoride deposits that maintain oral fluoride (F) after a topical F treatment. The purpose of this study was to examine if a high concentration of Ca would increase salivary F when used before a F rinse or dentifrice. We found that a Ca pre-rinse (150 mmol/l Ca lactate) or Ca dentifrice (0.084 g C...

background. hemostatic agents are applied to prepare an isolated bleeding-free condition during dental treatments and can influence adhesive restorations. this study evaluated the effect of a hemostatic agent (viscostat) on microleakage of contaminated dentinal margin of class v composite resin restorations with three adhesives. methods. sixty freshly extracted human molars were selected and cl...
