Objective: Repair of an indirect restoration is usually preferred over its replacement. This study aimed to evaluate the effect of silane in different surface preparation techniques on the bond strength of direct to indirect composite resin.   Methods: For this in vitro experimental study, 48 indirect composite cubes were fabricated, divided into 4 groups of 12 and subjected to the following ...

introduction: before placing or cementing a restoration into a cavity preparation, the clinician must decide whether a cavity base, liner or a protective cavity sealer should be placed. while this seems simple, the decision is complicated by an ever-increasing number of products available. in addition, the clinical success of an indirect restorative procedure depends, to a great extent, on the ...

Ceramics have been widely used for esthetic and functional improvements. The resin cement is the material of choice for bonding ceramics to dental substrate and it can also dictate the final esthetic appearance and strength of the restoration. The correct use of the wide spectrum of resin luting agents available depends on the dental tooth substrate. This article presents three-year clinical re...

The purpose of this in vitro study was to compare the microleakage of occlusal resin composite and three glass ionomer/ resin composite techniques. Class I occlusal preparations were initiated on forty molar teeth. Teeth were randomly assigned to four groups of ten. Groups were restored as follow: 1) Solo Plus / Point 4 resin composite, 2) Fuji IX/ Fuji Bond LC/ Point 4, 3) Fuji IX/ Experimenta...

In general excellent results cannot be guaranteed when using resin-based composites for posterior restorations. This is due to polymerization shrinkage which can still be regarded as the primary negative characteristic of composite resins. A review of available literature regarding the polymerization process, its flaws, and suggested strategies to avoid shrinkage stress was conducted. Several f...

Replacement of a restoration leads to excessive cutting of the otherwise healthy tooth structure which affects the integrity of teeth. Repairing existing glass ionomer restorations may appear to be a good alternative to complete replacement of the restoration which presents no evidence of failure on clinical exam. The objectives of the study were to determine the proportion of faculty advocatin...

AIM To compare the fracture resistance of thin-walled roots after restoration with different types of post systems. METHODOLOGY One hundred and sixty-five decoronated maxillary central incisors were root filled and randomly assigned to three groups with respect to the remaining dentine thickness of root (1.0 mm, 1.5 mm, 2.0 mm). Each group was randomly divided into five equal subgroups. The s...
