Although not a life-threatening condition, chronic bruxism often impairs the quality of life of affected individuals. In advanced stages, the condition might be accompanied by tooth sensitivity, abrasion, fractures, mobility, or loss, dental caries, alveolar bone loss, headaches, earaches and adverse cumulative, irreversible effect on dental implants and aesthetic restorations. Diminished facia...

Iatrogenic mandible fracture is a rare complication of tooth extraction with an incidence between 0.0033–0.0034%. This study retrospectively analyzes total 8 patients who underwent lower molar associated during removal in the period from April 2006 to March 2019. The assessed parameters were age and sex patients, method extraction, side distribution fracture, type extracted tooth, position thir...

INTRODUCTION Comparing the epidemiology of fractures originating in the cervical and apical regions may help to understand the causes and risk of a vertical root fracture. We aimed to determine the frequency of vertical root fractures in different fracture sites and how the fracture site relates to fracture direction and post length. METHODS Teeth diagnosed with a vertical root fracture were ...

Through an energy analysis of the cleavage cracking in a constant-K sample, the analytical solution of the dynamic fracture resistance for a brittle, homogeneous material is obtained. The dependence of the crack behavior on the accumulated continuum dissipation associated with the dynamic effect is analyzed. The relationship between the critical energy release rate of crack arrest and the appli...

Background: This report presents a case of a patient with multiple tooth fractures in posterior teeth that were diagnosed several months following an emergency intubation. Findings: A 68-year-old woman, with a history of an emergency intubation during ascending aorta dissection repair performed 7 months ago, presented with a complaint of long lasting pain in the right side of her face, and a re...

The chemical, physical, and mechanical characteristics of nickel-based superalloys are reviewed with emphasis on the use of this class of materials within turbine engines. The role of major and minor alloying additions in multicomponent commercial cast and wrought superalloys is discussed. Microstructural stability and phases observed during processing and in subsequent elevated-temperature ser...

PURPOSE The aim of this study was to investigate the accuracy of cone-beam computed tomography (CBCT) in the diagnosis of vertical root fractures in a tooth with gutta-percha and prefabricated posts. MATERIALS AND METHODS This study selected 96 extracted molar and premolar teeth of the mandible. These teeth were divided into six groups as follows: Groups A, B, and C consisted of teeth with ve...
