What is a "compomer"?

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 ...

Dyes for caries detection: influence on composite and compomer microleakage

Clinical Oral Investigations, 2002
The 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.

Localized wear of compomer restorative materials.

American journal of dentistry, 2002
To 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, 2004
A 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), 2001
A 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, 2004
This 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, 1999
The 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).

Compomer materials and secondary caries formation.

American journal of dentistry, 2002
To evaluate the role of compomers in secondary caries formation in vitro.36 human teeth with caries-free enamel (coronal) and root surfaces underwent a fluoride-free prophylaxis. Class V cavities were prepared in buccal and lingual coronal and root surfaces.

Bond strength of compomers to human enamel.

Operative dentistry, 2001
The study evaluated the tensile bond strength between human enamel and seven compomer restorative systems under different bonding conditions. Seven compomers were bonded to human tooth structure with and without phosphoric acid etching of the bonding surface, with and without the use of their recommended combined primer and bonding agent and with both ...

Solubility and fluoride release in ionomers and compomers.

Quintessence international (Berlin, Germany : 1985), 1999
The degree of solubility and the fluoride release of glass-ionomer cements and "compomers" were determined as a function of time.Three conventional glass-ionomer cements, three hybrid ionomers, and two compomers were included in the study. Disk-shaped specimens were prepared and immersed in a lactic acid solution.
