Assessing the fatigue resistance of NiTi instruments: A DSC-based approach to understanding temperature effects. [PDF]

Int Endod J
Abstract Aim This study aims to demonstrate that phase transformation analysis, assessed via differential scanning calorimetry (DSC), offers a more comprehensive understanding of NiTi instruments' mechanical behaviour than traditional fixed‐temperature fatigue testing by evaluating phase transformation temperatures and their impact on cyclic fatigue ...

Microbiome of Apical Intracanal and Extraradicular Biofilms From the Same Roots of Teeth With Persistent Apical Periodontitis: An Observational Study. [PDF]

Int Endod J
ABSTRACT Aim Bacterial biofilms around the apex are crucial in disease progression and persistence of apical periodontitis. While intracanal biofilms initiate infection, extraradicular biofilms contribute to treatment resistance and persistence. Thus, a comprehensive understanding of these biofilms may help elucidate mechanisms underlying persistent ...

Individualidad y conciencia en Plotino

Tópicos, 2022
La cuestión de la individualidad en Plotino es una de las más debatidas. A lo largo de las Enéadas, la problemática del sujeto individual se ve atravesada por la complejidad en la comprensión del hombre y del alma.

Role of the flat-designed surface in improving the cyclic fatigue resistance of endodontic NiTi rotary instruments [PDF]

, 2019
The aim of this study was to investigate the role of the flat-designed surface in improving the resistance to cyclic fatigue by comparing heat-treated F-One (Fanta Dental, Shanghai, China) nickel-titanium (NiTi) rotary instruments and similar prototypes,

Influence of Cavity Designs on Fracture Resistance: Analysis of the Role of Different Access Techniques to the Endodontic Cavity in the Onset of Fractures: Narrative Review. [PDF]

ScientificWorldJournal
Objectives. In recent years, new endodontic access techniques have been proposed with the aim of preserving as much dental tissue as possible for subsequent prosthetic rehabilitation. It has indeed been demonstrated that the success of this therapy is essential and dependent on the proper execution of endodontic cavity access.

Efficacy of imaging techniques for the diagnosis of apical periodontitis: A systematic review

International Endodontic Journal, Volume 56, Issue S3, Page 326-339, October 2023., 2023
Abstract Background Apical periodontitis (AP) is a chronic inflammatory response of microbial aetiology. Pathological changes associated with AP may not be visible on radiographic images and may linger without causing any symptoms. Clinicians rely mostly on clinical examination and imaging techniques to establish a diagnosis. Objectives The aim of this
