Research
Restoration Deterioration Related to Later Failure.
Clinical Relevance:
Replacement of restorations based on traditional signs thought to be associated with impending failure seems unnecessary.
Adhesive Interface between Resin and Etched Dentin of Cervical Erosion/Abrasion Lesions.
Clinical Relevance:
A thinner hybrid layer is seen in the occlusal portion of erosion/abrasion lesions. Further research is needed to determine the clinical relevance.
Composite Resin Bond Strength after Enamel Bleaching.
Clinical Relevance:
The shear bond strength of composites to enamel can be significantly reduced after bleaching. Delaying bonding procedures or grinding the superficial bleached enamel prior to bonding is recommended.
Clinical Trial to Evaluate the Retention of a Silver Cermet-Ionomer Cement Used as a Fissure Sealant.
Clinical Relevance:
Cermet-ionomers function well as dental sealants.
Effects of Design Features and Restorative Techniques on Marginal Leakage of MO Composites: an In Vitro Study.
Clinical Relevance:
Attention to preparation design and to restorative technique may not be sufficient to prevent marginal leakage of MO composites.
