Xylitol and the bactericidal effect of chlorhexidine and fluoride on Streptococcus mutans and Streptococcus sanguis.

The present study was made to investigate the effect of xylitol on the bactericidal and bacteriostatic action of chlorohexidine diacetate (CHX) and sodium fluoride (F) in ATCC strains of Streptococcus mutans and S. sanguis. Standardized bacterial cell suspensions were used in tests for bactericidal effect and for inhibition of growth and sucrose fermentation.

The effect of an experimental chewable antiplaque preparation containing chlorhexidine on plaque and gingival index scores.

This clinical cross-over trial investigated the effects of a chewable preparation containing chorhexidine-fluoride-xylitol, xylitol control tablets, or chlorhexidine mouthwash, twice daily, on plaque and gingival index scores of subjects refraining from mechanical cleaning of their teeth. Both preparations containing chlorhexidine were found to be efficient antiplaque agents when compared with the control. There was no statistically significant difference between the tablet preparation and conventional chlorhexidine rinsings with respect to the recorded parameters.

The effect of a combination of chlorhexidine diacetate, sodium fluoride and xylitol on plaque wet weight and periodontal index scores in military academy cadets refraining from mechanical tooth cleaning for 7-day experimental periods.

45 subjects participated in a double-blind cross-over mouthwash study where a new tablet-form combination of chlorhexidine, fluoride and xylitol (XYLIHEX) was studied together with solutions of chlorhexidine (CHX) and sodium fluoride (NaF). The preparation XYLIHEX was developed as a dental chemotherapeutic that could easily be added to the soldiers' kit to be used under circumstances where practising normal oral hygiene habits is restricted. For comparative purposes, XYLIHEX was prediluted in this study to make a solution.

Effect of caries in mentally handicapped children of addition of fluoride and bicarbonate-phosphate to dietary sugar products.

Mentally handicapped children, aged 5--15 years and living in institutions, received fluoride supplement in several sugar products of their diet; in candies, marmalades, jams, fruit juices and in sweet desserts corresponding to 10 mg F as NaF per kg of the sugar (sucrose or glucose) of each product. To two of the four daily candies was also added a NaHCO3 + KH2PO4 mixture (mole ratio 9.8/l, resp.
