Revolutionizing Dental Polymers: The Versatility and Future Potential of Polyetheretherketone in Restorative Dentistry.

Polyetheretherketone (PEEK) has emerged as a revolutionary material in modern dentistry because of its unique combination of mechanical strength, biocompatibility, and versatility. This literature review examines the current applications and future potential of PEEK in various dental disciplines. PEEK's favorable properties, including its low specific weight, high strength-to-weight ratio, and ability to be easily machined, have led to its adoption in prosthetics, implantology, and dental esthetic restorations.

Assessment and Evaluation of Consumer Awareness and Self-Medication Use Practices Towards Over the Counter (OTC) Analgesics. A Cross-Sectional Study in Abha-Saudi Arabia.

Objectives: To assess and evaluate consumer awareness and common medication use practices towards OTC analgesics, with a focus on the impact of irrational drug use and its implications for public health and safety. This includes identifying gaps in knowledge, evaluating the potential consequences of misuse, and discussing how these findings can inform future educational initiatives and policy development to promote safer medication practices.

Methods: This was a cross-sectional, semi-quantitative survey of 750 Saudi volunteers both males and females aged between 18 and 65 years.

Relative Survival, Conditional Survival, and Causes of Death in Patients with Early Gastric Cancer, with a Focus on Differences Between Cardia and Non-Cardia Cancer.

: Many researchers believe that cardia (CGC) and non-cardia (NCGC) are two different types of tumors, having different features like incidence rate, risk factors, geographical location, and socioeconomic status. This study aims to investigate the causes of death (COD) survival rates among early gastric cancer patients with a focus on differences between CGC and NCGC. : This retrospective study employed SEER*stat software (version 8.

Comparing distal and proximal radial access for percutaneous coronary intervention and angiography: a comprehensive meta-analysis and systematic review of randomized controlled trials.

Background: Distal radial access (DRA) through the anatomical snuff-box is a novel technique for coronary procedures. Emerging evidence suggests that DRA is associated with a lower risk of certain complications compared to proximal radial access (PRA).

Methods: A systematic review was conducted to compare clinical and procedural outcomes between both access sites for coronary angiography and percutaneous coronary intervention.
