Evaluation with Micro-CT of the Canal Seal Made with Two Different Bioceramic Cements: GuttaFlow Bioseal and BioRoot RCS.

Aim: The aim of this work is to investigate the quality of root canal seals obtained by comparing two bioceramic cements, GuttaFlow bioseal and BioRoot RCS, focusing on the presence of voids created during the canal obturation procedure.

Materials And Methods: The voids are analyzed using a micro-computed tomography (micro-CT) device. The study will be performed using images of the endodontic space before and after filling of a selected group of elements.

Cone-beam computed tomography accuracy in pulp chamber size evaluation: An ex vivo study.

This study aimed to assess ex vivo the accuracy of cone-beam computed tomography (CBCT), as compared to operative microscope, for evaluating pulp chamber size. A total of forty teeth were extracted for periodontal reasons and a horizontal section was done at the most apical level of the cement-enamel junction. The pulp chamber was photographed using a digital camera connected to an optical microscope.

Digital Orthopantomography vs Cone Beam Computed Tomography-Part 2: A CBCT Analysis of Factors Influencing the Prevalence of Periapical Lesions.

Aim: Cone beam computed tomography (CBCT) is the most refined and affordable method available today for the examination of an incoming patient for different dental pathologies. The aim of this paper is to evaluate the significance of some factors influencing the prevalence of apical periodontitis.

Materials And Methods: An ortopantomography (OPT) and CBCT scan of the dental arches were examined for each of the selected 45 patients.

Digital Orthopantomography vs Cone Beam Computed Tomography-Part 1: Detection of Periapical Lesions.

Aim: Digital orthopantomography (OPT) is usually the first examination step in supervising an incoming patient. Cone beam computed tomography (CBCT) is the most refined and affordable method to search for different dental lesions. The aim of this paper is to evaluate the effectiveness of OPT and CBCT in detecting periapical lesions in different dental groups.

A Micro-computed Tomography Evaluation of the Shaping Ability of Two Nickel-titanium Instruments, HyFlex EDM and ProTaper Next.

Introduction: The aim of this study was to evaluate and compare, by means of micro-computed tomography imaging, the shaping ability of ProTaper Next (PTN) and the novel HyFlex EDM (HFEDM) instruments.

Methods: Forty teeth were randomly divided into 2 groups and prepared with PTN or HFEDM. Root canal transportation and centering ratio were evaluated in mesiodistal and buccolingual directions at 5 levels (at the midpoint of the apical, middle, and coronal thirds and at the boundaries between them).
