Five-year Clinical Evaluation of Universal Adhesives in Noncarious Cervical Lesions.

Objectives: To compare the clinical performance of mildly acidic universal adhesives Scotchbond Universal (SU, 3M Oral Care, St Paul, MN, USA) and Prime & Bond Elect (PBE, Dentsply Sirona, Charlotte, NC, USA) in the restoration of noncarious cervical lesions (NCCLs).

Methods And Materials: A total of 63 patients in need of 203 NCCL restorations participated in this randomized controlled clinical trial. Notch-shaped lesions were restored with Kalore (GC Corporation, Tokyo, Japan) after application of either SU or PBE, following the etch-and-rinse (ER) or self-etch (SE) techniques.

Effect of immediate dentin sealing on load-bearing capacity under accelerated fatigue of thin occlusal veneers made of CAD-CAM glass-ceramic and resin composite material.

Objective: The objective of this study was to assess the influence of immediate dentin sealing (IDS) on the fatigue behavior of laminate occlusal veneers fabricated with CAD/CAM lithium disilicate ceramic and resin composite.

Methods: Forty sound human molars were prepared and randomly divided into 4 groups (n = 10): RC-IDS+ (IDS and resin composite occlusal laminate veneer); RC-IDS- (resin composite occlusal laminate veneer without IDS); LD-IDS+ (IDS and lithium disilicate laminate veneer); LD-IDS- (lithium disilicate occlusal laminate veneer without IDS). The restorations were obtained using a digital workflow.

Three-year clinical evaluation of universal adhesives in non-carious cervical lesions.

Purpose: To compare the performance of universal adhesives containing different monomers, namely 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) and dipentaerythritol penta-acrylate monophosphate (PENTA), in the restoration of non-carious cervical lesions (NCCLs).

Methods: This was a randomized controlled clinical trial involving 63 subjects in need of restorations of 203 NCCLs. Notch-shaped lesions were restored with Kalore (GC Corporation) after application of Scotchbond Universal (SU) or Prime&Bond Elect (PBE) following the etch-and-rinse (ER) or self-etch (SE) technique.

Eighteen-month Clinical Study of Universal Adhesives in Noncarious Cervical Lesions.

Objective: To evaluate the clinical performance of Scotchbond Universal (3M Oral Care) and Prime & Bond Elect (Dentsply Sirona) in the restoration of noncarious cervical lesions (NCCLs).

Methods And Materials: This was a randomized controlled clinical trial involving 63 subjects. Two hundred and three NCCLs were restored using Scotchbond Universal and Prime & Bond Elect using both an etch-and-rinse and a self-etch technique.

Effect of Surface Sealants and Polishing Time on Composite Surface Roughness and Microhardness.

The objective of this study was to evaluate the effect of surface sealants and polishing delay time on a nanohybrid resin composite roughness and microhardness. Eighty disc specimens were made with a nanohybrid resin (Esthet-X HD, Dentsply). The specimens were divided into two groups (n=40) according to polishing time: immediate, after 10 minutes; delayed, after 48 hours.

Color Match Between Composite Resin and Tooth Remnant in Class IV Restorations: A Case Series.

Rehydration of the tooth remnant and complete polymerization of the composite resin are aspects that should be considered in shade selection of composite resin. This article presents a case series of Class IV restorations performed to evaluate the color match between the composite resin and the tooth remnant. Thirteen Class IV restorations were performed in maxillary central incisors and evaluated according to the period following the restorative procedure: 10 minutes (baseline), 48 hours before and after finishing and polishing, and seven, 14, and 28 days.

A Conservative Technique for Repairing Class IV Composite Restorations.

Composite resin may make a restoration noticeable as time passes, on account of its color instability. The repair technique is a minimally invasive treatment for class IV composite resin restorations that show unsatisfactory coloration. Thus, the objective of the present article was to report a clinical case involving a conservative technique used for repairing a class IV composite resin restoration in the left maxillary central incisor and the replacement of a class IV restoration in the right maxillary central incisor.

Enamel hypoplasia: challenges of esthetic restorative treatment.

Enamel defects, such as white or yellow-brown spots, usually cause problems that are more esthetic than functional. Enamel hypoplasia may be the result of hereditary, systemic, or local factors. Dental trauma is a local etiologic factor.

Silorane adhesive system: a case report.

Silorane-based composite resin requires a specific adhesive system: a 2-step self-etching adhesive. Clinical protocols are well established and are based on the principles of adhesion to mineralized dental tissues. In this paper, we present a clinical application of the silorane adhesive system in a class-II restoration using silorane-based composite resin.

Influence of external and internal surface roughness modifications on ceramic flexural strength.

Statement Of Problem: After the occlusal adjustment of a ceramic restoration, polishing is necessary to promote surface smoothness and increase the ceramic flexural strength. However, the internal adjustment procedure may affect ceramic flexural strength.

Purpose: The purpose of this study was to evaluate the effect of external adjustment with or without the polishing procedure and of internal adjustments on the surface roughness and flexural strength of a ceramic.
