Abstract：AIM:To investigate the effects of chewing xylitol-containing gum on the microbial composition in oral cavity.METHODS:60 volunteers aged 18-22 years were included and randomly divided into 3 groups ( n=20):45 min chewing after lunch (group A), 15 min chewing after lunch (group B) and non-chewing control (group C) .Saliva was collected on day 21 and cultured on BHI, MSB and Rogosa agar plates for colony enumeration.RE-SULTS:Chewing xylitol-containing gum significantly decreased the level of total bacteria in saliva.However, no sig-nificant difference was observed between different duration of gum chewing.CONCLUSION:Chewing xylitol-contai-ning gum for 15 min is sufficient to suppress oral bacteria, further prolonging the duration of chewing may not necessari-ly enhance the inhibitory effect on oral microflora.
