Comparative evaluation of microleakage in class II cavities restored with Ceram X and Filtek P-90: An in vitro study

open access: yesContemporary Clinical Dentistry, 2012
Context: Polymerization shrinkage in composite resins is responsible for microleakage. Methacrylate-based composite resins have linear reactive groups resulting in high polymerization shrinkage.

Shear Bond Strengths of Methacrylate- and Silorane-based Composite Resins to Feldspathic Porcelain using Different Adhesive Systems

open access: yesJournal of Dental Research, Dental Clinics, Dental Prospects, 2015
Background and aims. Use of porcelain as inlays, laminates and metal-ceramic and all-ceramic crowns is common in modern dentistry. The high cost of ceramic restorations, time limitations and difficulty of removing these restorations result in delays in ...
