| Abstract: | Objective To study the influence of salivary lipids on the adherence of cariogenic bacteria (S.mutans Ingbritt and BF; S.sobrinus OMZ176 and 6715). Methods Mixed saliva was collected from 10 healthy subjects (5 males and 5 females, aged 21～23). The salivary lipids was depleted under nondenatural condition (-10℃, ethanol∶ether 3∶2 V∶V ). The adherence of S.mutans and S.sobrinus to the experimental pellicles formed from mixed saliva or lipids-depleted saliva was investigated with 3H-TdR incorperation assay. Results The amount of S.mutans Ingbritt and BF adhered to lipids-depleted pellicle were significantly increased (P<0.05). The amount of experimental bacteria adhered to lipids-depleted pellicle or mixed salivary pellicle were following the regular pattern: Ingbritt>BF>OMZ176>6715. Conclusion Salivary lipids significantly decreased the number of S.mutans adhered to pellicle. |
