Objective This study was designed to investigate the effect of certain pathological alterations of the dental structures (diminishing bone support, internal resorption, root perforation, periapical lesion) on stress distribution during root canal filling procedures by the warm vertical compaction technique.

In this study, the stress distribution in a maxillary central incisor subjected to an endodontic treatment was determined by using a three-dimensional finite-element method, The tooth had a variable root canal cross-sectional area, and the canal was assumed to be filled with vertical condensation. The Clinical practice was simulated by considering the obturation in successive stages, The main aim of the study was to investigate the possibility of fracture due to the obturation process, It was found that, wi...

Objectives/Hypothesis: To evaluate airway sufficiency and airflow dynamics in a group of patients who underwent a posterior transverse laser cordotomy (PTLC) procedure.
Design and mechanical analysis of a new dental implant that would mimic natural tooth with a periodontal ligament
Pektaş, Ömer; Tönük, Ergin; Department of Mechanical Engineering (2012)
Dental implant is an artificial dental root that is used to construct dental restorations, similar to the original teeth, in order to regain the function of missing teeth of patients experiencing tooth loss. At the interface between the jawbone and the roots of natural teeth, a thin, elastic, shock absorbing tissue, called the periodontal ligament (PDL), forms a cushion which provides certain mobility to the natural teeth. The restorations supported by dental implants, however, involve completely rigid stru...

The objective of this study was to predict time-dependent bone remodeling around tissue- and bone-level dental implants used in patients with reduced bone width. The remodeling of bone around titanium tissue-level, and titanium and titanium-zirconium alloy bone-level implants was studied under 100 N oblique load for one month by implementing the Stanford theory into three-dimensional finite element models. Maximum principal stress, minimum principal stress, and strain energy density in pen-implant bone and ...
Evaluation of Threshold Values for Root Canal Filling Voids in Micro-CT and Nano-CT Images

While several materials and techniques have been used to assess the quality of root canal fillings in micro-CT images, the lack of standardization in scanning protocols has produced conflicting results. Hence, the aim of this study was to determine a cutoff voxel size value for the assessment of root canal filling voids in micro-CT and nano-CT images. Twenty freshly extracted mandibular central incisors were used. Root canals were prepared with nickel titanium files to an ISO size 40/0.06 taper and then fil...
