Linking periodontal pathogens with endoperio lesions.

Endodontic-periodontal diseases pose difficulties for the practitioner in diagnosing and predicting the success of the affected teeth. Therefore, it is of interest to correlate between periodontal infections and endodontic periodontal disorders. 50 patients of both sexes were included in this study. 28 of the 50 patients were men and 22 were women. Participants with a history of endodontic and periodontal lesions on the same tooth were chosen. A polymerase chain reaction experiment was carried out and relationships were formed. Data shows that isolates of Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans and Tannerella forsythia were identified in 91% of the periodontium, 12% of the endodontium, and 51% of the endodontium, respectively. Targeted bacterial species were associated with periodontal and endodontic disorders that occurred concurrently. Therefore, it is plausible to speculate that dentinal tubules serve as a channel for the dissemination of microorganisms.
