Abstract(s)
As infecções endodônticas são influenciadas pela localização, composição do biofilme e características dos materiais dentários utilizados. Os canais radiculares com periodontite apical associada pós-tratamento, persistente/secundária, indicam que houve uma falha na desinfecção durante o Tratamento Endodôntico Não-Cirúrgico. Neste caso, os microrganismos podem ter tolerado os procedimentos químicos-mecânicos (infecção persistente) ou invadido o espaço canalar por preenchimento radicular tridimensional deficitário (infecção secundária). Este trabalho revê os aspectos microbiológicos da infecção endodôntica, especialmente quando a lesão ocorre após o Tratamento Endodôntico Não-Cirúrgico do canal radicular. Oferece perspectivas para futuras investigações bem como orientações na prevenção desta patologia.
Endodontic infections are influenced by the location, biofilm composition and features of the dental materials used. Root canals with post-treatment associated apical periodontitis, persistent/secondary, indicate that disinfection failed during Non-Surgical Endodontic Treatment. In this case, the microorganisms may have tolerated the chemico-mechanical procedures (persistent infection) or invaded the pulpal space by deficient three-dimensional root filling (secondary infection). This work reviews the microbiological aspects of endodontic infection, especially when the lesion occurs after non-surgical endodontic treatment of the root canal. It offers prospects for future research as well as guidance in the prevention of this pathology.
