A Black Pigmented Strain: Porphyromonas Endodontalis and Its Role in Endodontics

Introduction: Anaerobic gram-negative bacteria play essential role in the development of periodontal and endodontic diseases. Anaerobic, black-pigmented Porphyromonas endodontalis (previously Bacteroides endodontalis) is a rod of Gram-negative bacteria linked to endodontic inflammation.

Materials and Methods: Using keywords like P. endodontalis, periapical periodontitis, gram-negative anaerobic bacteria pigmented in black, endodontic inflammation and more, pertinent publications about P. endodontalis were gathered and chosen from PubMed, google scholar.

Results: It has been identified from submucous abscesses of endodontic origin as well as infected dental root canals. It has been observed that the presence of P. endodontalis in infected dental root canals is associated with acute infection symptoms. The present paper is to review and evaluate the literature on P. endodontalis, including information on virulence factor, diet, epidemiology, detection, and treatment.
