Conclusion Adhesion to the prosthesis base is improved with surface treatments .
Rough surfaces and changes in hardness compromise the material 's serviceability
Purpose The objective of this systematic review is to compare results concerning the properties of adhesion , roughness , and hardness of dental liners obtained in the last ten years .
Biofilm formation on denture liners in a randomised controlled in situ trial.
OBJECTIVES This r and omised clinical trial assessed how biofilm development and composition is affected by time and denture material type in denture wearers with and without denture stomatitis . METHODS Specimens of acrylic resin ( control ) and denture liners ( silicone-based or acrylic resin based , depending on the experimental phase ) were inserted into the surface intaglio of 30 denture wearers . Biofilm was formed in two phases of 21 days , and counts of viable micro-organisms in the accumulating biofilm were determined after 7 , 14 and 21 days of biofilm formation . Data were analysed by three-way ANOVA followed by Tukey test to assess differences among health condition ( healthy or with denture stomatitis ) , material s and time point . RESULTS Non-albicans C and ida species counts were higher in diseased patients with silicone-based denture liners ( p=0.01 ) . Denture stomatitis patients showed higher mutans streptococci counts after 7 days ( p=0.0041 ) . CONCLUSIONS Longer biofilm formation time periods did not result in differences on biofilm composition . The denture liners evaluated in this study accumulate greater amount of biofilm , and therefore their use should be carefully planned . CLINICAL SIGNIFICANCE The silicone-based denture liner tested should be used cautiously in patients with denture stomatitis as it showed increased non-albicans species counts , known to be difficult to treat
