Microbiological Profile in Endodontic-periodontal Lesion

Abstract

Endodontic-periodontal lesion is a clinical manifestation of the pathologic intercommunication between pulpal and periodontal tissues. In general, these lesions are multifaceted in nature and can have a varied pathogenesis. Fundamental to our understanding of the pulpoperiodontal lesions is the key role of the pathogenic ecosystem that exists within this complex structure. Evidence suggests that there exists a wide range of microbial species in the periapical and periodontal tissues and that their concurrent pathogenesis is constantly linked to the bacterial interrelations between the two tissue types. Understanding the microbial involvement is of utmost significance as it offers a rationale for differential diagnosis and subsequent management of such lesions. This review has attempted to provide a basic insight on the microbiome or the microbial flora entailed in the bidirectional pathogenesis of endodontic-periodontal lesions.
