Setting Reaction of Polyacid Modified Composite Resins or Compomers [PDF]

The Open Dentistry Journal, 2009
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

Compomers Reinforced with Bioactive Glass and Hydroxyapatite Particles.

Oral health & preventive dentistry, 2019
To understand the effect of the addition of hydroxyapatite (HA) and bioactive glass (BAG) to compomer restorative materials on the remineralisation capacity of the material.1%, 2%, 3% and 4% w/w HA and BAG particles were added mechanically to the compomers. To examine the resistance to demineralisation, Class V cavities were prepared in extracted teeth

Systematic Reviews Comparing Direct and Indirect Restorations: An Umbrella Review That Examines Restoration Type and Confidence in Results

Clinical and Experimental Dental Research, Volume 11, Issue 3, June 2025.
ABSTRACT Objectives There are two technologies for restoring individual structurally defective teeth. A direct restoration is applied chairside in one appointment, while an indirect restoration needs to be lab‐produced before application. This umbrella review of previous English systematic reviews was conducted to determine if there was any difference ...
