Performance
Ferooz M, Basri F, Negahdari K, Bagheri R; Fracture Toughness Evaluation of Hybrid and Nano-hybrid Resin Composites after Ageing under Acidic Environment; Journal of Dental Biomaterials, 2015;2(1), Shiraz University.
Aim: To compare the fracture toughness (KIC two types of resin composites under tensile loading and to assess the effect of distilled water and latic acid on the resistance of the restoratives to fracture after three months of immersion.
Results:
The results of two-way ANOVA did not show a significant combined effect of material, time, and storage medium on fracture toughness (p=0.056). However, there was a strong interaction between materials and time ((p=0.001) when the storage medium were ignored. After 24h of immersion in distilled water, Paradigm revealed the highest Klc values followed by Rok, Luna and Estelite. Immersion in either distilled water or lactic acid significantly decreased the fracture toughness of almost all materials as time interval increased.
Conclusion:
As time increased, Klc significantly decreased for almost all resin composites except for LUNA which showed a slight decrease after one month of immersion in distilled water.

Aim: To investigate the load-beraing capacity of hybrid and nano-hybrid resin composites stored dry or wet up to 30 days, using Hertzian indentation test.
Conclusion: After seven days of immersion in distilled water, the load capacity of Filtek Supreme had significantly lower values than those of Rok and Luna.
Invitro performance
Kreitzer M et al; Strength Testing of Various Cements and Restorative Materials; Boston 2014 IADR Abstract # 1124, Tufts University.
Aim: To investigate the shear bond strength, compressive strength and flexural strength for select cements and composites
Conclusion: Luna composite has the highest flexural strength.
