Effect of Thermo-mechanical Load Cycling on Microleakage in Class II Ormocer Restorations
OBJECTIVES The objective of this in vitro study was to evaluate the marginal sealing ability of an ormocer in comparison with a hybrid composite when using thermocycling and load cycling procedures together in the study design. METHODS Modified proximal Class II cavities were prepared on the mesial and distal surfaces of twenty-two human premolars. Each tooth was restored with Admira and cont...
متن کاملEffect of Three Light Curing Protocols and Load Cycling on Microleakage of Class V Composite Restorations
Objective: Different methods have been suggested to overcome the polymerization shrinkage of composite restorations. Changing the light curing protocol to improve polymerization by using new light curing units is among these methods. The new devices are more efficient, portable and durable and produce less heat. This study aimed to assess the marginal microleakage of class V composite restora...
متن کاملEffect of mechanical load cycling on class V glass- ionomer and composite restorations; a microleakage and scanning electron microscopic evaluation
Received: 9 June 2011 Accepted: 29 August 2011 Abstract Background and Aim: Microleakage is an important problem with direct restorations and familiarity with its contributing factors is of utmost importance. The aim of this study was scanning electron microscopic evaluation of marginal integrity in three types of class V tooth-colored restorations and the effect of load cycling on their microl...

متن کاملEffect of Thermocycling and Type of Restorative Material on Microleakage of Class II Restorations
Objectives: Microleakage is a major cause of failure of dental restorations and results in development of secondary caries, tooth hypersensitivity and pulp pathosis. This study aimed to compare the microleakage of class II cavities filled with two types of composite resins and a compomer and subjected to thermocycling. Methods: In this in vitro experimental study, class II cavities with a gi...
