Assessment of Pulp Vitality in Multirooted Teeth With Advanced Periodontal Disease: A Clinical and Histological Study.

Background/purpose: The relationship between endodontic and periodontal lesions remains a controversy. Their diagnosis is often difficult and requires an interdisciplinary approach to rule out the cause and provide appropriate treatment. Periodontitis as an etiology of pulpal necrosis and irreversible pulpitis has been a hypothetical concept.

Estimation of salivary lactate dehydrogenase in oral squamous cell carcinoma, oral leukoplakia, and smokers.

Introduction: Lactate dehydrogenase (LDH) is an enzyme seen within every cell during their normal metabolic function. It is always confined within the cell cytoplasm and it becomes extracellular only when a cell dies. The extracellular presence of LDH is related to cell necrosis and tissue breakdown.
