Adhesion of a compomer to dental structures.
Quintessence international (Berlin, Germany : 1985), 1998The objective of this study was to evaluate the bond strength of a compomer to dental enamel, dentin, and cementum. Flat surfaces of these tissues were obtained from recently extracted human teeth. The different substrates were either treated with PSA (a primer and adhesive) or acid etched (35% phosphoric acid gel) and treated with PSA.

Journal (Canadian Dental Association), 1999
"Compomers" are recently introduced products marketed as a new class of dental materials. These materials are said to provide the combined benefits of composites (the "comp" in their name) and glass ionomers ("omer"). Based on a critical review of the literature, the author argues that "compomers" do not represent a new class of dental materials but ...

To compare the clinical performance of Dyract, Spectrum-TPH and Dyract layered with Spectrum-TPH (sandwich) in Class II restorations of permanent dentitions.23 adult patients aged 25-62 were selected at random in a general dental practice. Each patient had 3 bicuspid teeth restored with Dyract, Spectrum-TPH and a "sandwiched" combination where Dyract ...

Dyes for caries detection: influence on composite and compomer microleakage
Clinical Oral Investigations, 2002The aim of this study was to evaluate the influence of caries-detecting dyes on the microleakage of adhesive materials. Sixty cubic class V cavities were prepared on buccal and lingual surfaces of 30 human third molars. Coronal margins were located in enamel and gingival margins in cementum.

Analysis of surface roughness of glass–ionomer cements and compomer
Journal of Oral Rehabilitation, 2003summary The purpose of this study was to evaluate the surface roughness of two glass–ionomer cements (Vitremer and Chelon‐Fil), and one compomer (Dyract) when submitted to different finishing/polishing procedures at different times. A hundred 80‐sample discs were made of each material and randomly divided into six finishing/polishing groups: mylar ...

Localized wear of compomer restorative materials.
American journal of dentistry, 2002To determine and compare the localized wear of six compomer restorative materials.Ten specimens of Dyract, Dyract AP, F2000, Compoglass F, Elan and Hytac were prepared in a custom fixture and polished. A pretest surface profile was generated using an MTS 3-D surface profilometer and the specimens were subjected to 400,000 cycles in a Leinfelder wear ...

Multi-colored dual-cured compomer.
Pediatric dentistry, 2004A new polyacid-modified resin-based composite (compomer) restorative material has been introduced. Unlike other compomers, this material undergoes both chemical polymerization and photocuring hardening reactions. The new compomer is called MagicFil, and its chief attraction to children is that it is manufactured in 4 different colors, all with glitter ...

Simplified adhesion of compomers in pediatric dentistry.
Quintessence international (Berlin, Germany : 1985), 2001A self-etching adhesive agent for bonding polyacid-modified resin-based composite materials ("compomers") to enamel and dentin is now available. The Prompt L-Pop system simplifies and hastens dental bonding procedures and has proved itself useful in many adhesive dentistry applications.

Fracture resistance of compomer and composite restoratives.
Operative dentistry, 2004This study evaluated and compared the fracture toughness of compomers and composites. Three compomer (Compoglass F [CG], Vivadent; F2000 [FT], 3M-ESPE; Dyract Posterior [DP], Dentsply) and three composite (Tetric Ceram [TC], Vivadent; Z250 [ZT], 3M-ESPE; Esthet X [EX], Dentsply) restoratives were selected for the study.

Mechanical properties of compomer restorative materials.
Operative dentistry, 1999The purpose of this study was to measure the compressive strength, flexural strength, microhardness, and surface roughness of three compomers (Compoglass, Dyract, and Hytac) and compare the values to the ones obtained for a resin-modified glass-ionomer cement (Vitremer) and a resin composite (Z100).
