Apical actinomycosis as a continuum of intraradicular and extraradicular infection: case report and critical review on its involvement with treatment failure

Journal of Endodontics
Domenico Ricucci, José F Siqueira

Abstract

This article reports a case of extraradicular actinomycosis that clearly formed a continuum with the intraradicular infection. Histobacteriologic and histopathologic analyses of the root tip and attached apical periodontitis lesion obtained by surgery from a tooth with persistent disease were performed to look for the possible reasons for persistent disease. Although no stainable bacteria were observed in the apparently well-treated main canal, apical ramifications were clogged with dense bacterial biofilms that were contiguous to extraradicular actinomycotic aggregates. A critical review of the literature revealed that there is no clear evidence that apical actinomycosis is indeed an independent entity leading to persistent apical periodontitis lesions.

Biofilm formation is a key virulence factor for a wide range of microorganisms that cause chronic infections.Here is the latest research on biofilm and infectious diseases.

Antifungals

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.

Biofilms

Biofilms are adherent bacterial communities embedded in a polymer matrix and can cause persistent human infections that are highly resistant to antibiotics. Discover the latest research on Biofilms here.

Actinomycosis

Actinomycosis is a rare, chronic, and slowly progressive granulomatous disease caused by filamentous Gram positive anaerobic bacteria from the Actinomycetaceae family (genus Actinomyces). The disease is characterised by the formation of painful abscesses in the mouth, lungs,breast or gastrointestinal tract. Discover the latest research on actinomycosis here.
