ABSTRACT
Objective To explore the effects of chlorhexidine aeetate and trielosan on inhibition of microorganism adhesion on soft denture-lining materials. Methods Silicone rubber soft denture- lining material and resin soft denture-lining material were soaked in 0. 2% chlorhexidine acetate and 0. 1% trielosan for 5 minutes. Then the colony numbers of three different microorganisms (streptococcus mutans, actinomyces viscosus, candida albicans) adhering to soft denture-lining materials were counted. Results The colony numbers of candida albicans were (121.0±7. 0) × 105 cfu/ml in resin soft denture-lining material and (208. 8±8. 6) × 105cfu/ml in silicone rubber soft denture-lining material (P<0. 05). But there were no differences in colony numbers of streptococcus mutans and actinomyces viseosus. After soaked in chlorhexidine acetate and triclosan, the colony numbers of streptococcus mutans were significantly reduced to (87.1±4. 3)× 105cfu/ml, (61.6± 7.9) × 105cfu/ml, (42.1±8.2) × 105cfu/ml and (21.3±4.3)× 105cfu/ml, and the colony numbers of candida albicans were significantly reduced to (11.6±3.6) × 105cfu/ml, (11.1±3. 7) × 105cfu/ml, (41.6±3.0) × 105cfu/ml and (44. 6±4.1)× 105cfu/ml(all P<0. 01). However, chlorhexidine acetate and triclosan had no effects on actinomyces viscosus. There were no significant differences in the action effects between the two detergents (P>0. 05). Conclusions Chlorhexidine acetate and trielosan can effectively inhibit the adhesion of microorganism on denture-lining materials, which are useful in clinic.
