In recent years lot of research is being done on its application in the field of medicine and particularly in restorative dentistry. These materials found to be successful for restoration of teeth in esthetic, function and to maintain the integrity of masticatory muscles. Some of the dental materials, the biocompatibility and application has been discussed and reviewed.

Materials and Methods: Conventional posterior glass ionomer restorative cement- Fuji IX was used as the control group (control-GIC). Experimental group was prepared by incorporating zinc oxide nano particles of size <50nm into the powder of Fuji IX at 3% W/W concentration with P/L ratio 3.6:1. The antibacterial activity of the set material against Streptococcus mutans was assessed using the agar diffusion test. The compressive strength and shear bond strength were measured using the Universal testing machine. Data was analyzed using Independent T test.
Results: Experimental group showed significant increase in antibacterial properties for both set and unset specimens. Incorporation of ZnO nanoparticles has no significant difference over the mechanical properties of set Glass Ionomer Cement.
Conclusion: The study showed significant increase in antibacterial property of set GIC with ZnO nanoparticles without modifying the mechanical properties. Thus incorporation of ZnO nanoparticles in glass ionomer cement can be considered as a better alternative to conventional GIC.

adhesives by using meta-analysis.
Materials and Methods: Potential papers that were selected according to inclusion and exclusion criteria from articles were
published in 13 peer-reviewed journals using “PubMed data base”. From each report, means and standard deviations of bond
strengths were extracted and tabulated with corresponding experimental conditions.
Results: All the studied parameters showed no significant difference, except for dentin origin/site and bonding area. In
addition, statistical analysis done with ANOVA showed statistical significance between the one-step and two-step self-etch
adhesives.
Conclusions: Our analysis has showed that two-step self-etch adhesive system showed a superior in vitro performance in
comparison to one-step self-etch system. Nevertheless, certain factors such as dentin origin, site and area of bonding affect
the bond strength of adhesives.
