AIM This study compared several traditional culture-based media and chairside cultural assays for ability to recover mutans streptococci (MS) from pure cultures and from saliva samples. METHODS AND RESULTS When pure cultures were used with traditional culture-based media, mitis-salivarius bacitracin (MSB) agar demonstrated less support for bacterial(More)
BACKGROUND One strategy for treating dental caries is to suppress oral mutans streptococci, or MS, with chlorhexidine, or CHX, mouthrinse. Oral MS levels, however, tend to quickly return to baseline values without further intervention. In this clinical study, the authors evaluated the effect of xylitol chewing gum on MS regrowth. METHODS The authors(More)
OBJECTIVE To determine whether there is a difference in the oral/dental health in older persons with different life styles and medical status. STUDY DESIGN Survey (cross-sectional study) included four groups: (1) subjects (n = 123) living in a residential retirement home or community dwelling; (2) subjects (n = 218) seeking dental treatment at a Veterans(More)
The effect of multiple treatments with chlorhexidine mouth guards on salivary levels of mutans streptococci (MS) was studied. Eleven subjects with salivary MS > or = 10(5) CFU/ml were randomly assigned to an experimental or control group. Complete-arch mouth guards were coated internally with one of two ethylcellulose varnishes, one containing 30% dry w/w(More)
Xylitol-sweetened chewing gum has cariostatic properties, but is not suitable for all patients. This study evaluated the effect of xylitol rinse on mutans streptococci (MS) levels in the mouth. One hundred and five subjects with high salivary MS levels were randomly assigned to one of three groups. Subjects in the positive control group (N = 35) chewed two(More)
