Title: Reducing microleakage in composite resin restorations: an in vitro study. Author: Unlu N, Krakaya S, Ozer F, Say EC. Journal: Eur J Prosthodont Restor Dent; 2003 Dec; 11(4):171-5. PubMed ID: 14737794. Abstract: The purpose of this in vitro study was to evaluate the effect of a resin lining on microleakage around composite resin restorations. Standard slot cavities were prepared on the approximal surfaces of 48 extracted human molar teeth. The cavities were restored with two conventional or two condensable composite resins, placed with or without a flowable composite resin lining. The teeth were subjected to thermal stress and immersed in dye solution. Dye penetration was viewed with both a stereomicroscope and a scanning electron microscope. Flowable resin lining material under condensable composites may be beneficial in reducing microleakage around cervical margins.[Abstract] [Full Text] [Related] [New Search]
