Recurrent spontaneous abortions (RSA) is defined as a loss of two or more consecutive clinically recognized pregnancies before the 20th week of gestation. In RSA, several causative maternal factors are known, but still, 50% of the cases remain unexplained. Evidence suggests that paternal factors are also equally important.

Statement Of The Problem: During endodontic therapy, irrigation solutions applied in the root canal may affect the physicochemical properties of the dentinal wall, thereby changing its microhardness. This may adversely affect the sealing ability and adhesion of dental materials. Therefore, many studies have focused on the search for an ideal root canal irrigant that has a minimal effect on dentinal microhardness.

Introduction: The need to perform restorations with a natural appearance is one of the most challenging aspects of dentistry, and reproducing the colour of natural teeth in restorations is a clinical challenge due to the complex optical characteristics of dentition. Various procedures have been advocated in the literature to correct dental anomalies, particularly in the aesthetic region, such as tooth discoloration due to fluorosis or dentition spacing due to changes in tooth shape, such as peg laterals.

Clinical Applications: Veneer are one of the most commonly used treatment modalities in such cases.

Lumbar radiculopathy, characterized by pain radiating along a nerve root, significantly diminishes the quality of life due to its neuropathic nature. Patients' understanding of their illness and the coping strategies they employ directly influence how they manage their condition. Understanding these illness representations from the patient's perspective is crucial for healthcare providers seeking to optimize treatment outcomes.

Article Synopsis
  • The study aimed to evaluate how different designs and metals of endodontic rotary files distribute stress against the root canal walls using finite element analysis.
  • A total of 60 rotary files were categorized into four groups based on their metallurgy and design, then analyzed for stress impact during root canal simulation.
  • Results showed that while XP-endo Shaper files produced the least stress and F360 files produced the most, no significant differences were found among the groups, suggesting advancements in file design could reduce stress and the risk of breakage without compromising performance.
