INTRODUCTION The aim of this in vitro study was to compare the effect of Gates-Glidden and Peeso reamer drills on residual dentin thickness during post space preparation in order to discover which method has minimum root structure damage. MATERIALS AND METHODS Thirty extracted human maxillary premolars with bifurcations at root middle were horizontally cut 15 mm coronal to the apical end afte...

this study is aimed to evaluate the effect of covering exposed root surface by collagen membrane and to compare this method with coronoally advanced flap covering. 26 teeth in 20 patients (12m/8f) with miller1 gingival recession were selected. 14 teeth were allocated into test group and 12 teeth in control group. following first phase of treatment, clinical parameters including the height and w...

The paper discusses the interaction of ex ante and ex post institutional convergence in the post-Soviet world, i.e. 12 members of the Commonwealth of Independent States. It starts with analysing empirical evidence for institutional convergence in the CIS, and then considers two channels of convergence: institutional competition for mobile capital and ex ante harmonization via interaction in pol...

INTRODUCTION To evaluate the effect of two different post space diameters and related resin cement film thicknesses on the bond strength of a polyfiber post. MATERIALS AND METHODS A total of 48 premolars were randomly divided into two according to the post space diameter: 1.1 mm and 1.5 mm. Then each group was divided into three sub-groups according to luting cement used: RelyX U100, Panavia ...

systems rehabilitation steps on the strain and temperature rise on apical and cervical root dentin regions. Twenty-one extracted human canine teeth had two strain gages attached to the distal root surface and two thermocouples attached to the mesial root surface (cervical and apical). The strain and temperature rise were recorded during the following procedures: root canal preparation, final ri...
