Maternal Lead Exposure Induces Glandular Alterations in the Salivary Glands of Rat Male Offspring

Environmental Toxicology, EarlyView.
ABSTRACT Lead (Pb) is a widely distributed environmental pollutant that is highly noxious due to its toxicokinetic characteristics. Pb exposure can damage vital organ systems, including the central nervous and stomatognathic systems. As salivary glands play an important role in oral homeostasis, this study aimed to investigate the effects of maternal ...
