Fracture Toughness of Nanohybrid and Hybrid Composites Stored Wet and Dry up to 60 Days
Conclusions:Wet storage adversely affected the fracture toughness of almost all materials. Keeping the restoration dry in the mouth may increase their fracture toughness. Therefore, using a coating agent on the surface of restoration may protect them from early water uptake and increase their strength during a time period.Key words:Nanohybrid, Hybrid Composite,Fracture Toughness,Wet/Dry Storage (Source: Journal of Dental Biomaterials)

Antimicrobial Effect of Copper Oxide Nanoparticles on Some Oral Bacteria and Candida Species
Conclusions:With respect to the potential bactericidal activity of CuO NPs on various cariogenic bacteria examined in this study, these NPs could be introduce as a candidate control agent for preventing dental caries or dental infections. In our study, on the other hand, Nano copper oxide had a weak effect on the candida species.Key words: Nanoparticle,Oral Streptococcus, Lactobacillus, Yeast, Dental Caries (Source: Journal of Dental Biomaterials)

Colour Stability of Various Types of Acrylic Teeth Exposed to Coffee, Tea and Cola
Conclusions:Despite the significant colour change in the three groups, ΔE in Ivoclar group was within the clinically acceptable range of ≤ 3.3. A slight colour change was expected regarding the Apple and PolyDent acrylic teeth clinically.Key words:Colour Stability, Acrylic Teeth, Spectrophotometer, Colouring Solutions (Source: Journal of Dental Biomaterials)

Laboratory Comparison of the Anti-Bacterial Effects of Spearmint Extract and Hypochlorite Sodium on Enterococcus Faecalis Bacteria
Conclusions:Considering the limitations of an experimental study, it seems that spearmint extract does not have any anti-bacterial effect against Enterococcus faecalis bacteria, in contrast to hypochlorite sodium 5.25%.Key words:Hypochlorite Sodium, Spearmint Extract, Root Canal Irrigation, Enterococcus faecalis (Source: Journal of Dental Biomaterials)

Comparison of Microtensile Bond Strength of Silorane-Based Composite with the Conventional Methacrylate Composite to the Dentin of Primary Teeth
Conclusions:As the second group (etch + silorane bond system + composite Filtek P90) exhibited higher microtensile bond strength, it may prove that using composite Filtek P90 is preferable to be used in primary dentin in comparison with composite Filtek Z250, and using etch + silorane bond system is more advantageous than single bond system.Key words: Microtensile Bond Strength, Silorane Adhesive System, Methacrylate Composite, Self-etch Primer (Source: Journal of Dental Biomaterials)

A One-Year Evaluation of a Free Fissure Sealant Program
Conclusions:Many factors affect the success rate of a fissure sealant therapy program. The type/brand of the material remained significantly related to the success rate of the fissure sealant even after adjustments for other influencing factors. In this study, ClinproTM Sealant (3M/ESPE, USA) showed better longevity after one year of application.Key words:Pit and Fissure Sealants, Preventive Dentistry, Molar (Source: Journal of Dental Biomaterials)

Combination Effect of Hemostatic and Disinfecting Agents on Micro-leakage of Restorations Bonded with Different Bonding Systems
Conclusions:Hemostatic agent contamination had no significant effect on micro- leakage of total- and self-etching adhesive systems. Application of chlorhexidine after the removal of hemostatic agent increased micro-leakage in self-etching adhesives but did not affect when total-etching was used.Key words:Chlorhexidine, Hemostatic Agent, Micro-leakage, Self-etching Adhesive,Total-etching Adhesive (Source: Journal of Dental Biomaterials)

The Effect of Bulk Depth and Irradiation Time on the Surface Hardness and Degree of Cure of Bulk-Fill Composites
Conclusions:The DC of the investigated bulk fill composite was better than the universal type in all the irradiation times and bulk depths. The studied universal and bulk fill RBCs had an appropriate DC at the 2 and 4 mm bulk depths respectively and using the recommended curing time of 40s can led to the slightly better value of DC in both composites.Key words: Bulk-fill Composites, Irradiation Time, Microhardness, Degree of Cure (Source: Journal of Dental Biomaterials)
