Microbiological aspects of endoperiodontal lesion

Resumo

The endoperiodontal lesion occurs when a tooth
undergoing endodontic disease is united to a periodontal lesion with
apical progression. Many times, the differential diagnosis between
the endodontic and periodontal disease can be of difficult execution
and the correct diagnosis and planing of the treatment is of main
importance for a good prognosis Objective: To identify the main
microorganisms within the lesion of endodontic and periodontal
origin and correlate them with the endoperiodontal lesion. Literature
review: The search strategy comprised the electronic studies of
databases such as PubMed and Cochrane on the microbiology of
the endodontic and periodontal systems through employing the
following keywords: microbiology, endodontics, periodontal pocket.
Results: There were similarities in the endodontic and periodontal
microflora. However, the number of microorganisms within the cross
infection is limited, including Bacteroides, Eubacteria, Fusobacteria,
spirochaetes, Wolinella. The bacterias forming the red complex are
closely related to the severity of the periodontal disease and can
also participate in the pathogenesis of the periradicular abscesses.
Conclusion: There are many communication routes between the
periodontium and pulpal tissue, therefore the contamination from
um tissue to another can occur, existing a microbiological interrelationship between these tissues.
