Universal Versus Glass Ionomer –Based Adhesive: Effect On Shear Bond Strength And Micro-Morphological Analysis Of Resin Modified Glass Ionomer Restorative Material /Dentin Interface, Gehad Mohamed Kassem, Huda Abed El -Haliem Mohammed, Ashraf Ibrahim Ali

Mansoura Journal of Dentistry

Objectives: : To evaluate universal versus glass ionomer –based adhesive, effect on shear bond strength and micro-morphological analysis of resin modified glass ionomer restorative material /dentin interface.

Materials and methods: 120 sound human molars were selected for our study. Subsequently, teeth were prepared by removing the occlusal enamel and exposing mid dentin. The roots of teeth were fixed to the base of a tube filled with acrylic resin. Teeth were divided into two groups according to type of RMGI (n=60) and then each group was subdivided into three subgroups according to adhesive use (n=20). Cylindrical tubes were built by the …

Effect Of Manufacturing Techniques And Surface Treatment Of Custom-Made Polyetheretherketone Posts On The Shear Bond Strength To Resin Cement Versus Customized Fiber Posts, Manar H. Emara, Marwa M. Wahsh, Mostafa M. Nour

Mansoura Journal of Dentistry

Objective

To study the impact of two surface treatments (air abrasion and piranha solution), and different manufacturing techniques of Polyetheretherketone (PEEK) compared with Fiber Post as a controlled group on the shear bond strength of the endodontically treated teeth.

Methods

35 single-rooted maxillary incisors were divided into five groups of 7 each. The fiber post was silanated according to manufacture and then bonded with dual-cure resin cement. While PEEK posts were made using various fabrication methods (Computer-aided design/computer-aided manufacturing (CAD/CAM) and Press), and were exposed to two surface treatments (air abrasion and piranha solution).

Results

The study materials did not …
