Subchronic Exposure to Cannabis‐Based Nanoemulsions Induces Histopathological and Molecular Alterations in the Rat Submandibular Gland

Journal of Applied Toxicology, EarlyView.
ABSTRACT The increasing therapeutic incorporation of cannabis has expanded phytocannabinoid application, yet peripheral adverse effects like xerostomia raise concerns regarding emerging biotechnological formulations. This study evaluated the effects of cannabis‐based lipid nanoemulsions on the rat submandibular gland parenchyma.

Microbial burden of periodontal diseases and its clinical application: The stage, grade, and furcation matter

Journal of Periodontology, EarlyView.
Abstract Background Periodontal diseases are associated with dysbiotic oral microbial communities, but clinically applicable measures that reflect microbial burden across disease severity and progression remain limited. This study aimed to assess the oral microbial burden of periodontal diseases by evaluating salivary and subgingival lipopolysaccharide
