The purpose of this study was to evaluate the interfacial strength and microleakage pattern of paired light-cured restorations. Two small particle (SP), two pure hybrid (HB) and two microfilled materials (MF) were selected. Cylindrical molds were used to prepare double layer specimens for the groups SP-HB, SP-MF, HB-MF and the controls. The last group was comprised of double layer specimens respectively. All the samples were immersed in normal saline at 37 degrees C and divided in two series. The first series included samples immersed in normal saline for 24 h and accelerated aged for 1 h in saline at 37 degrees C plus 1000 times thermal cycling between 5 degrees-60 degrees C. These samples were sheared off at 0.005 inch/min cross-head speed.

Although posterior composites have evolved considerably, both clinical studies and experience have confirmed that several problems still remain concerning their clinical properties and the relative complexity of handling the material. In order to resolve these problems, two different manufacturers have introduced composite resin systems for the fabrication of direct or indirect resin inlays and onlays which are cemented into the acid-etched preparation with a modified composite resin. Both systems are based on the same concept: the polymerization of the resin takes place out of the mouth in a special oven where a specific heat-curing procedure is followed. There is an essential difference between the two systems. When the direct resin system is used, the inlay is formed and partly light-cured into the tooth preparation, then it is removed for further polymerization. When the indirect system is used the procedure takes place in the lab where the inlay is formed on the die.

In this study, the thermal diffusivity of three types of dental cements, were measured. Thermal diffusivity was determined by the following method. Two thermo-couples were used and connected to a chart record, the first was embedded in the cylindrical block of the cement specimen and the other in a mixing of ice and water (reference thermocouple). All them were set in a apparatus consisting of a double cooling bath. Calculation of thermal diffusivity were based on the curve provided of the record during cooling of the cement and a theoretical mathematic model. Values were ranged from 2,985 to 3,934 cm2.sec-1. ZOE cement exhibited the highest value, the glass-ionomers the lowest and the poly-carboxylates were average.
