Introduction: Post and core has been considered for endodontically treated tooth, especially in cases with severe damage crowns. Recently fiber reinforced composite posts (FRC post) have been used in the treatment of endodontically treated teeth. Because the length and diameter of posts are effective in stress distribution, the purpose of this study is to evaluate the effect of length and diame...

-----------------------------We show that the (interim) fine core of an atomless exchange economy with differential information is a subset of the ex-post core of the economy. Moreover, the interim fine core may be empty, and therefore it may be a proper subset of the ex-post core. The inclusion relation does not hold for economies with a finite number of traders.

OBJECTIVES Aim of the study was to measure the adhesion between two types of translucent prefabricated FRC posts (FRC Postec, Ivoclar-Vivadent, FRC; Light-Post, RTD, LP), and two types of flowable composites used as core materials (UnifilFlow, GC, UF; Tetric Flow, Ivoclar-Vivadent, TF), with or without the application of a silane (Monobond-S, Ivoclar-Vivadent, S) on the post surface. METHODS ...

AIM To review the literature on the sealing ability of esthetic post systems with different cementation techniques. BACKGROUND An important factor for successful root canal treatment is the development of a coronal seal to the treated root canal system. Review result: The current literature describes promising results using fiber posts with a dual-cure, self-etch resin cement system. However,...

Abstract Introduction & Objective: A stroke is a chronic disease and has a lot of complications following a reduction in the quality of life from the common problems of these patients. The aim of this study was to Comparison of the effect of Core stability exercises with Otago exercises on quality of life in patients with stroke. Materials & Methods: This study is a clinical trial in which th...

OBJECTIVES The aim of this study was to integrate existing knowledge of in vitro strength of post-and-cores and masticatory loading to arrive at longevity estimates for post-and-core restorations when subjected to clinically relevant loads. METHODS A biomechanical model was developed to predict the in vivo longevity. This method was applied to direct post-and-core restorations with amalgam or...
