The actual mechanism of fluoride action is still a subject of debate. A dogma has existed for many decades, that fluoride has to be ingested and acts mainly pre-eruptively. However, recent studies concerning the systemic effect of fluoride supplementation concluded that the caries-preventive effect of fluoride is almost exclusively posteruptive. Moreover, epidemiologists have cast doubt on the ...

This study was performed to compare the remineralizing effects of various concentrations of fluoride containing dentifrices against artificial demineralization of primary enamel. One hundred twenty primary incisors were partly covered with a nail varnish, leaving a 1 x 1 mm window, then placed in demineralizing solution for 96 hours to produce artificial carious lesions 60-100 microm in depth. ...

Fluoridated toothpastes were designed to produce a topical caries-preventive effect. Many studies have shown their effectiveness. Recently, researchers have expressed concern that fluorosis may be increasing in the American population. There is speculation that fluoride (F) from fluoridated toothpastes might be a contributing factor when the toothpaste is accidentally swallowed by small childre...

BACKGROUND Surface microhardness is a physical property which access the effect of chemical and physical agents on hard tissues of teeth, and a useful way to examine the resistance of fluoride treated enamel against caries. The purpose of this study was to evaluate microhardness of enamel following pH-cycling through demineralization and remineralization using suspensions of dentifrices with di...

OBJECTIVE To obtain information on the level of total fluoride intake from food, beverages and toothpaste by children at the age of 22-25 months of low and high socioeconomic status (SES) in major Colombian cities. METHODS Daily fluoride intake was assessed by the duplicate plate method and by recovered toothpaste solution during a 3-day period and afterwards analysed by the microdiffusion me...

AIM The present study was conducted to evaluate the effcacy of commercially available herbal toothpastes against the different periodontopathogens. MATERIALS AND METHODS Six herbal toothpastes that were commonly commercially available were included in the study. Colgate herbal, Babool, Meswak, Neem active, Dabur red toothpastes were tested for the study whereas sterile normal saline was used ...
