The Influence of Saliva, Artificial Saliva and Propolis Extract on the Wettability of Heat−Cured and Visible Light−Cured Denture Base Material

Aims: To evaluate and compare the effect of human saliva, artificial saliva and propolis extract on the wettability of heatcured and visible light cured denture base material .Materials and Methods: A total of 80 samples were prepared , 40 samples prepared from heat cured resin and the other 40 samples were prepared from light cured resin. These two groups were divided into four subgroups, control group, human saliva, artificial saliva and propolis. Contact angle measurements by sessile drop method with a micropipette using digital camera to determine the wettability of these samples. Mean values were compared statistically with one way analysis of variance (ANOVA),Duncan's multiple range test and ttest to determine the significant difference among the tested groups. Results: There is a signifi-cant differences of the mean values of the contact angle among the tested groups. The contact angle significantly decreased in all the treated samples. Conclusion: Heat cured resin has more wettability than light cured resin. Human saliva, artificial saliva and propolis increased the wettability of both heat cured and light cured resin
