Purpose: The abutment teeth of removable partial dentures are susceptible to root surface caries and secondary caries, and such caries sometimes result in crown destruction. In particular, in aged patients, this risk increases due to age-associated gingival recession, periodontal disease, decreased amount of saliva, and inadequate brushing caused by decreased finger motor function. Fluoride-rel...
BACKGROUND Saliva has a high nitrite concentration, derived from the enterosalivary recirculation of dietary nitrate, and is the main source of nitrite entering the acidic stomach. Acidification of nitrite in the presence of secondary amines or amides generates potentially carcinogenic N-nitroso compounds. The reaction is inhibited by ascorbic acid and catalysed by thiocyanate. AIM To determi...

A bacterial agglutinin specific for strains of Streptococcus mutans was isolated from human saliva. Physiochemical analyses showed the agglutinin to be a glycoprotein with a molecular weight of 60,000. The agglutinin aggregated four of the eight strains of Streptococcus mutans tested but did not aggregate the strains of Streptococcus salivarius, Streptococcus sanguis, and Streptococcus mitis te...
