Research
In Vitro Caries Inhibition Effects by Conventional and Resin-modified Glass-Ionomer Restorations.
Clinical Relevance:
Fluoride release and fluoride uptake by dentin from conventional and resin-modified glass-ionomer restorations gave dentin resistance to the development of recurrent wall carious lesions.
Diffusion Behaviour of Eugenol from Zinc Oxide-Eugenol Mixtures through Human and Bovine Dentin In Vitro.
Clinical Relevance:
Materials containing eugenol should not be applied to deep cavities.
Marginal Adaptations of Composite Fillings versus Hybrid Ionomer/Composite Sandwich Fillings.
Clinical Relevance:
Hybrid ionomer/composite sandwich fillings have good marginal qualities and may be an alternative to composite fillings using a dentin bonding system.
Contouring, Finishing, and Polishing Class 5 Restorative Materials.
Clinical Relevance:
None of the polishing techniques tested could reproduce matrix smoothness and gloss.
4-META Polymethyl Methacrylate Shear Bond Strength to Titanium.
Clinical Relevance:
The application of 110um alumina air abrasive to titanium frameworks prior to processing with head-cured PMMA (Meta-Dent) will increase the shear bond strength by more than three times over the nonair-abraded titanium surface.

Research
Shear Bond Strengths of 10 Adhesive Resin/Amalgam Combinations.
Clinical Relevance:
The combination of a filled adhesive resin with a spherical amalgam alloy may produce improved bond strengths.
The Effect of a Training Program on the Reliability of Examiners Evaluating Amalgam Restorations.
Clinical Relevance:
The training program improved the reliability of examiners evaluating the clinical serviceability of the amalgam restorations.
Postoperative Pain Following Bonded Amalgam Restorations.
Clinical Relevance:
This double-blinded clinical trial using OptiBond was unable to substantiate claims that a dentinal adhesive liner used in conjunction with amalgam restorations nearly elimates postoperative sensitivity to cold.
Five-Year Treatment Outcomes for Teeth with Large Amalgams and Crowns.
Clinical Relevance:
Large amalgams (four and five surfaces) exhibited more favorable 5-year outcomes than generally assumed.
Strength Properties of Visible-Light-cured Resin-modified Glass-Ionomer Cements.
Clinical Relevance:
The strength properties of various brands of light-cured resin-modified glass-ionomer cements depend greatly upon their curing conditions and chemistry.
A Comparison of Antimicrobial Activity of Etchants Used for a Total Etch Technique.
Clinical Relevance:
Intentional treatment with disinfectants or antimicrobials may not be necessary in light of the antimicrobial activity of phosphoric acid etchants.

Research
Surface Roughness and Cutting Efficiency of Composite Finishing Instruments.
Clinical Relevance:
Finishing diamonds were best suited for gross removal and contouring of structured composite surfaces; for finishing, the tungsten-carbide burs achieved the best results.
Computer-Assisted Densitometric Image Analysis (CADIA) of Previously Sealed Carious Teeth: A Pilot Study.
Clinical Relevance:
Occlusal dental caries can be arrested by sealing the lesions without decay removal, and the teeth can be maintained up to 10 years.
The Anticariogenic Effect of Fluoride in Primer, Bonding Agent, and Composite Resin in the Cavosurface Enamel Area.
Clinical Relevance:
The use of glass-ionomer cement may prevent the initial caries on the cavosurface enamel margin, whereas composite resins that include fluoride in the primer, bonding agent, or composite resin may not prevent it.
Fit of Veneers Made by CAD-CAM and Platinum Foil Methods.
Clinical Relevance:
The fit of CEREC CAD-CAM glass-ceramic veneers was very slightly inferior to platinum foil porcelain veneers.
Fracture Resistance of Complex Amalgam Restorations.
Clinical Relevance:
Amalgambond Plus combined with pins provided significantly greater resistance to fracture than pins or Amalgambond Plus alone.
A Comparison of Two Teaching Simulations in Preclinical Operative Dentistry.
Clinical Relevance:
Ceramic-coated teeth are an acceptable alternative to human teeth in teaching preclinical operative dentistry.

Research
Biocompatability of Compomer Restorative Systems on Nonexposed Dental Pulps of Primate Teeth.
Clinical Relevance:
Compomers are not irritating to pulp when bacterial microleakage is excluded by a proper clinical seal.
Resin-Dentin Shear Bond Strength and Interfacial Ultrastructure with and without a Hybrid Layer.
Clinical Relevance:
Shear bond strengths were significantly enhanced by removing the collagen network with NaOCl after conditioning the dentin with phosphoric acid for All-Bond 2 dentin adhesive and were not significantly different for Scotchbond Multi-Purpose.
Comparison of Aesthetic Properties of Tooth-colored Restorative Materials.
Clinical Relevance:
Composite resins had better hue-chroma, value, and translucency match to the Vita shade guide than the other materials evaluated, although none was rated good or excellent.
Literature Review
Detection of Microleakage around Dental Restorations: A Review.
Clinical Relevance:
Dentists can better evaluate marginal integrity of restorative materials if they understand how microleakage studies are conducted.

Research
Shear Bond Strengths of One-Bottle Dentin Adhesives Using Multiple Applications.
Clinical Relevance:
Multiple applications of one-bottle adhesives had little effect on composite shear bond strength to dentin.
Comparison of Retentiveness of Amalgam Bonding Agent Types.
Clinical Relevance:
Amalgam bonding agents with greater film thickness exhibited the greatest retention.
In Vitro Corrosion Behavior and Microstructure Examination of a Gallium-based Restorative.
Clinical Relevance:
The gallium-based restorative material tested is more corrosion prone than a high-copper amalgam and may undergo accelerated corrosion when placed adjacent to a high-copper amalgam.
The Effect of Internal Bevel on Marginal Leakage at the Approximal Surface of Class 2 Composite Restorations.
Clinical Relevance:
An internal bevel of the cervical margins of class 2 composite restorations reduces marginal leakage compared to a conventional butt-joint cavity preparation.
Progression of Dental Demineralization with and without Modified Tunnel Restorations in Vitro.
Clinical Relevance:
Modified tunnel restorations utilizing glass-ionomer cement may inhibit the progression of demineralization.

Marginal Adaptation of Dental Composites Containing Prepolymerized Filler.
Clinical Relevance:
Complete marginal adaptation to the cylindrical dentin cavities was observed in two commercially available composites (Estelite and Silux Plus).
The Effect of Alcoholic and Nonalcoholic Mouthwashes on Heat-treated Composite Resin.
Clinical Relevance:
Heat-treated composites soaked in mouthwashes containing alcohol gained significantly more weight than those soaked in nonalcoholic mouthwashes.
