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.

Lymph Node Yield/Ratio, Neutrophil-Lymphocyte Ratio: Prognostic Factors in cN0 Laryngeal Carcinoma.

Objectives: The aim of this study was to investigate the role of lymph node yield (LNY), lymph node ratio (LNR), and neutrophil to lymphocyte ratio (NLR) as prognostic factors, their impact on survival in patients with advanced laryngeal squamous cell carcinoma (LSCC).

Methods: This multicentric retrospective study included 195 patients with clinical N0 advanced laryngeal carcinoma who underwent total laryngectomy and/or total pharyngolaryngectomy over 5 years. The number of lymph nodes extracted (LNY) and the number of positive nodes were counted.

Tracheal resection anastomosis for rare tracheal inflammatory lesions mimicking malignancy: report of 2 cases.

Background: Tumor-like lesions of the trachea are rare and challenging in diagnosis and management. Inflammatory myofibroblastoma, also known as Inflammatory pseudo tumors (IPTs), as well as Rosai Dorfman Disease (RDD) are inflammatory lesions that may involve the central airways with variable non-specific clinical features mimicking tumors.

Case Presentation: In this study 2 cases with tumor-like lesions are presented.
