Calculation of colour resulting from composite/compomer layering techniques
Journal of Oral Rehabilitation, 2004summary This study determined the influence of optical properties of constituent layers on the colour of double‐layer aesthetic filling materials. Multiple regression equations for the Commission Internationale de I'Eclairage (CIE) L*, a* and b* of layered materials were calculated from the optical values of the covering and underlying layers ...

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 ...

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).

Effect of enamel pretreatments on bond strength of compomer
Dental Materials, 2001The objective of this study was to evaluate the effect of various enamel surface treatments on the bond strength of a compomer to enamel.Ground bovine enamel specimens were divided into four groups. A compomer (F2000, 3M) was bonded to the specimens using different enamel surface treatments.

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 ...

Polymerization contraction stress in light-cured compomer restorative materials
Dental Materials, 2003The magnitude and kinetics of polymerization contraction stress build-up may be potential predictors of bond failure of adhesive restorations. The present study determined these properties of seven commercial compomers (Dyract, Dyract AP, F2000 Rasant, Hytac, Compoglass F, Luxat, Glasiosite).Polymerization shrinkage was generated by 40 s light curing ...

Discoloration of a compomer by stains.
The Journal of the Greater Houston Dental Society, 1998This study evaluated the color stability of a polyacid-modified composite (compomer) upon exposure to stains. Five disks were prepared for immersion in each of five stains: coffee, chlorhexidine, cola, red wine, and water as a control. Color measurements were made on a reflection spectrophotometer at baseline, after 24-hour incubation, and after 24, 48,

Compomer materials and secondary caries formation.
American journal of dentistry, 2002To 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.

[Amalgam, composite and compomer: microbiological study].
Odonto-stomatologie tropicale = Tropical dental journal, 2012Restorative materials have different consequences on the periodontium. The surface of these materials may influence gingival health and cause in some instances gingival inflammation. The purpose of this study was to investigate and compare, in a healthy periodontium, intracrevicular plaque bacteria (Aggregatibacter actinomycetemcomitans, Porphyromonas ...

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.
