The Impact of Two Cordless Retraction Materials on Inflammatory Biomarkers Interleukin-1 Beta and Tumor Necrosis Factor-Alpha in Gingival Crevicular Fluid: An In-Vivo Study.

Introduction: This study aimed to evaluate and compare the inflammatory responses of two cordless gingival retraction systems by assessing the levels of interleukin-1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) in gingival crevicular fluid (GCF).

Association of Mast Cell Activity With Chronic Gingivitis, Chronic Periodontitis, and Aggressive Periodontitis in Adults: A Histochemical Observational Study.

Introduction: Periodontal diseases, including chronic gingivitis, chronic periodontitis, and aggressive periodontitis, are driven by complex immune responses, with mast cells (MCs) playing a pivotal role through the release of mediators during degranulation. Although MC involvement in chronic periodontal conditions has been documented, its role in aggressive periodontitis and the relationship between MC degranulation and inflammation intensity remain poorly understood. This study aimed to quantify MCs and assess their degranulation in gingival tissues across healthy gingiva, chronic gingivitis, chronic periodontitis, and aggressive periodontitis using histochemical staining to elucidate their role in periodontal inflammation and disease progression.

Two-Point Versus Three-Point Fixation in Zygomaticomaxillary Complex (ZMC) Fractures: A Narrative Review.

Zygomaticomaxillary complex (ZMC) fractures are among the most prevalent facial injuries encountered during maxillofacial surgery because of the anatomical prominence and structural significance of the zygoma. These fractures often result from high-energy impacts, such as road traffic accidents, assaults, falls, and sports injuries, predominantly affecting males in their third to fourth decades of life. The management of ZMC fractures requires restoring facial aesthetics, orbital integrity, and masticatory function while minimizing surgical morbidity.
