The relative efficacy of NaF silica toothpastes containing 1000 ppm fluoride and 1500 ppm fluoride in the control of dental caries is not clear-cut. Also, it has not been established that incorporation of trimetaphosphate (TMP) improves the anticaries activity of NaF toothpastes.

Forty-three children living in North Wales, an area with a temperate climate, were involved in this study from September 1990 until June 1991 inclusive. By standardizing the method and timing of collection the effect of external factors on the salivary flow rate was minimized. Flow rate was assessed once a month. Of the original group of 43, 18 attended at(More)
Calcium, phosphate and buffering capacity were measured in children's (n=43) unstimulated saliva between September 1990 and June 1991 inclusive. Saliva samples were collected in the afternoon, once a month, on 10 consecutive occasions. Buffering capacity was assessed immediately after sample collection using the Dentobuff strip method. The remainder of the(More)

Although many older studies used unreliable indices, there is some evidence that clinically significant periodontitis is now restricted to between 15 and 20% of the population with(More)
