Metallic materials have widespread use in dentistry for clinical treatment and restoration of teeth. Major areas of usage are: (1) restorative dentistry and prosthodontics (dental amalgam and gold alloy restorations for single teeth, metallic restorations for multiple teeth, including metal-ceramic restorations, removable partial denture frameworks, and dental implants), (2) orthodontics (wires...

Clinicians are frequently challenged by endodontically treated teeth that have obstructions, such as hard impenetrable pastes, separated instruments, silver points or posts in their root canals. Intracanal separation of endodontic instruments may hinder cleaning and shaping procedures within the root canal system, with a potential impact on the outcome of treatment. Broken instruments usually p...

INTRODUCTION The performance and mechanical properties of nickel-titanium (NiTi) instruments are influenced by factors such as cross-section, flute design, raw material, and manufacturing processes. Many improvements have been proposed by manufacturers during the past decade to provide clinicians with safer and more efficient instruments. METHODS The mechanical performance of NiTi alloys is s...

Considering that many individuals hesitate to visit the dental clinics and hence they tend to avoid visiting dental clinics. This hesitation is due to the stomatological anxiety. Therefore, anxiety may often lead to severe oral health issues. Anxiety of the patients sometimes may result in the failure to provide excellent dental care by the dental health care providers. Studies have shown that ...

Due to its pseudo elastic behavior, the nickel-titanium (nitinol) alloy has been used in the manufacture of endodontic instruments in recent years, being especially useful for curved canals preparation. Extensive research has been carried out to improve the wear resistance of the nitinol instruments without create modifications in the bulk of the files. The purpose of this work was to measure t...
