Tensile Bond Strength, Fit Accuracy and Failure Types of Zirconia and Cast Gold Root Copings for Overdentures.

Aim: To compare the tensile strength, dislodgement forces, marginal gap and failure types between digitally fabricated zirconia root copings and conventionally manufactured cast gold root copings.

Methods: Extracted human teeth (N=30) were prepared for the root copings and randomly divided into 2 groups: (1)zirconia root copings(ZC) and gold root copings(GC). The specimens were tested for tensile bond strength and dislodgement forces in a universal testing machine and the types of the coping failures modes were analyzed.

Effect of a novel irrigation regimen and root canal filling material versus conventional endodontic protocols on dentin wettability.

The purpose of this study was to compare the effect of different irrigation regimens on the dentin wettability of root canal sealers. The occlusal surfaces of human molar teeth (N = 90) were removed, polished, and divided into three groups (n = 30) based on the irrigation regimen: control group (SAL), standard irrigation group (NES), and test group (ODC). Each group was randomly divided into three subgroups according to the root canal sealer: AH Plus (AHP), Total Fill BC Sealer HiFlow (TOT), and OdneFill (ODF).

Analysis of the Cranial Aperture of the Optic Canal in Patients with Chiari Type-I Malformation.

Aim: To examine the morphological properties of the cranial aperture of the optic canal (CAOC) in patients with a Chiari type-I malformation (CIM).

Material And Methods: Radiological images of 40 patients with CIM (24 females/16 males, mean age: 20.75 ± 14.

Assessment of the Anterior Clinoid Process and Optic Strut in Chiari Malformation Type I: A Computed Tomography Study.

 This study aimed to evaluate morphological features of the anterior clinoid process (ACP) and the optic strut (OS) in Chiari malformation Type I (CM-I).  The study universe consisted of computed tomography images of 41 CM-I patients and 45 normal subjects. Comparison of the parameters for CM-I and the control group was performed with the Student's -test.

Analysis of the Prechiasmatic Sulcus in Chiari Malformation Type I.

Objective: To assess morphologic features of the prechiasmatic sulcus (PS) in Chiari malformation type I (CM-I).

Methods: Computed tomography images were obtained in patients with CM-1 (mean age: 21.26 ± 16.
