A 3-year clinical evaluation of a compomer, a composite and a compomer/composite (sandwich) in class II restorations.

American journal of dentistry, 2003
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 ...

Analysis of surface roughness of glass-ionomer cements and compomer

Journal of Oral Rehabilitation, 2003
summary  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, 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 ...
