This study evaluated Vickers hardness, flexural strength and flexural modulus of two flowable composites (ESTELITE FLOW QUICK, Tokuyama Dental Corp; Filtek Flow, 3M ESPE) when light cured using a halogen light (optilux501, Kerr Corporation) and two LED lights (L.E.Demetron1, Kerr Corporation; Flashlite, Discus Dental). Working times were also compared.
Recently, new self-etching resin cements have been introduced into the dental market. The purpose of this study was to determine the bond strength of three dual-cured, self-adhesive cements (Embrace WetBond Universal Resin Cement, Pulpdent; Maxcem, Kerr Corporation; RelyX Unicem Self-Adhesive Universal Resin Cement, 3M ESPE) using light- and self-cured modes to bond pre-cured composite to […]

THE DENTAL ADVISOR recently completed a four-year recall of over 1500 restorations cemented with 3M ESPE RelyX Unicem Self-Adhesive Universal Resin Cement (3M ESPE). At four-year recall, less than 1% of the restorations require recementation, less than 5% of the restorations had evidence of microleakage, and less than 2% of the patients reported occasional temperature […]
3M ESPE RelyX Unicem Self-Adhesive Universal Resin Cement (3M ESPE) has adequate bond strength for the cementation of veneers but THE DENTAL ADVISOR does not recommend this technique. RelyX Unicem can undergo a color change with aging that could affect the esthetics of thin veneers. THE DENTAL ADVISOR has observed slight discoloration/microleakage at the margins […]
Self-adhesive resin cements are well suited for any cementable dental restoration. This would include ceramic-metal, all-metal, and high-strength ceramic inlays, onlays, crowns or bridges, and posts of all types. This type of cement is not recommended for restorations such as feldspathic or pressble ceramic crowns and porcelain veneers. There are many self-adhesive products on the […]
Yes, Impregum Penta Soft Quick Step (3M ESPE) is a quick setting version of their proven polyether impression material. Polyethers are known for their stiff, accurate, and water-friendly (hydrophilic) properties. The impression material is sold in three viscosities: light, medium, and heavy. The medium body is used in a monophase technique. Heavy- and light-bodied materials […]
Yes, THE DENTAL ADVISOR has reported four-year results of an ongoing clinical evaluation of 3M ESPE Filtek Supreme Plus (3M ESPE), a nano-filled light-cured composite for anterior and posterior direct restorations.

Alginate substitutes [AlgiNot (Kerr), 3M ESPE Position Penta Quick (3M ESPE), Silgimix (Sultan HealthCare), StatusBlue (Zenith Dental/DMG)] are addition silicone impression materials that provide improved handling and properties as compared to traditional alginates.
Alginate substitutes [AlgiNot (Kerr Corp.), 3M ESPE Position Penta Quick (3M ESPE), Silgimix (Sultan HealthCare), StatusBlue (Zenith Dental/DMG)] can be used for any procedure for which alginates are usually used. Examples of uses include pre-operative provisional impressions; impressions for diagnostic casts, night guards and bleaching trays; and duplicate impressions of existing diagnostic casts. Alginate substitutes […]
3M ESPE Lava Crowns and Bridges (3M ESPE )are a milled zirconia coping (using CAD/CAM technology) overlaid with feldspathic ceramic for optimal strength and esthetics. They are indicated for anterior or posterior crowns and for 3- and 4-unit bridges (maximum span 38 mm). They can be cemented with traditional crown and bridge cements. In a […]
Use of the unfilled resin component of a bonding agent as a “wetting” agent appears to be a common practice. Choose the unfilled resin portion of a 4th-generation bonding agent [3M ESPE Adper Scotchbond Multi-Purpose Plus Adhesive System (3M ESPE)] rather than an adhesive system with a primer. Use a small amount so that surface […]
The sandwich technique involves the use of glass ionomer [GC Fuji II (GC America)] or resin-modified glass ionomer [GC Fuji II LC (GC America); 3M ESPE Vitrebond Plus Light Cure Glass Ionomer Liner/Base (3M ESPE)] as a base with posterior composite restorations and is popular outside of the United States. Because the glass ionomer has […]
Yes, alginate substitutes [AlgiNot (Kerr Corp.), 3M ESPE Position Penta Quick (3M ESPE), Silgimix (Sultan HealthCare), StatusBlue (Zenith Dental/DMG)] have improved properties that can result in impressions that are more accurate than alginate impressions. Alginate substitutes have higher tear energy and do not tear as easily when removed from thin sulcular areas of the mouth. […]
Adper Single Bond Plus (3M ESPE) is a 5th-generation (total-etch) adhesive that includes 10% by weight silica nanofiller particles. Nanofillers can potentially strengthen the adhesive layer. The adhesive comes in either a bottle or unit-dose packaging. The unit-dose delivery system includes a foil blister pouch, which must be pressed to deliver the material to the […]
The tooth structure of anterior teeth is too thin to mask the darkness of the oral cavity with a translucent composite. Always use a kit with opaque shades [3M ESPE Filtek Supreme Plus Universal Restorative (3M ESPE); Estelite Sigma (Tokuyama Dental Corp./Tokuyama America Inc.)]. Use an opaque composite as the base on the lingual side […]
Alginate substitutes (Alginot/Kerr Corp., 3M ESPE Position Penta Quick/3M ESPE, Silgimix/Sultan HealthCare, Status Blue/Zenith Dental Products/DMG) are addition silicone elastomers that are much more dimensionally stable than alginates (irreversible hydrocolloids) because they do not absorb or evaporate water. Alginate substitutes are packaged for quick and easy dispensing. They are also packaged for automatic mixing, which […]
