Setting Reaction of Polyacid Modified Composite Resins or Compomers
The hardening of modified polyacid composite resins (compomers) and glass-ionomers have been studied using infrared spectroscopy. The acid-base reaction in Ketac-fil, a glass ionomer, was followed by the ratio between the COOH band located around 1715 cm⁻¹ and that corresponding to COO⁻ located around 1570 cm⁻¹. The combination of infrared analysis and band narrowing treatments enable us to pro...
متن کاملSurface hardness properties of resin-modified glass ionomer cements and polyacid-modified composite resins.
In this study the top and bottom surface hardness of two polyacid-modified composite resins (PMCRs), one resin-modified glass ionomer cement (RMGIC), and one composite resin were evaluated. The affect of water storage on their hardness was also investigated. The study was conducted using four different groups, each having five specimens obtained from fiberglass die molds with a diameter of 5 mm...
متن کاملPolyacid-modified composite resins ("compomers") and their use in clinical dentistry.
OBJECTIVES This paper describes the chemistry and properties of polyacid-modified composite resins ("compomers") designed for use in clinical dentistry, and reviews the literature in this area. METHODS Information has been obtained from over 50 published articles appearing in the dental and biomaterials literature, with studies being principally identified through MedLine. RESULTS Published...
متن کاملThe Interaction of Polyacid-modified Composite Resins ("compomers") with Aqueous Fluoride Solutions
OBJECTIVE The aim of this study was to investigate how the release of fluoride from two compomers and a fluoridated composite resin was affected by exposure to KF solution. MATERIAL AND METHODS Two compomers (Dyract AP and Compoglass F) and one fluoridated composite (Wave) were prepared as discs (6 mm diameter and 2 mm thick), curing with a standard dental lamp. They were then stored in eithe...
متن کاملLongevity of a resin-modified glass ionomer cement and a polyacid-modified resin composite restoring non-carious cervical lesions in a general dental practice.
BACKGROUND Long-term prospective survival studies of resin-modified glass ionomer cements (RMGICs) and polyacid-modified resin composites (compomers) placed in non-carious cervical lesions (NCCLs) are lacking from general dental practice. Short-term studies have shown an unsatisfactory clinical performance for several materials. METHODS One practitioner placed 87 compomer (Compoglass, Vivaden...
