Desinfección foto activada frente al enterococcus faecalis en la irrigación de conductos radiculares. Revisión narrativa

Abstract

ABSTRACT

The main objective of endodontic preparation is the cleaning and disinfection of the root canals. The irrigation and shaping of the root canals are considered very important phases to achieve the success of endodontic therapy. Enterococcus faecalis (E. faecalis) is a Gram positive anaerobic cocco with the ability to survive in the root canal, it can invade the dentin tubules and resist the action of antimicrobial substances, it is the main microorganism related to the failure of endodontic therapy. One of the current techniques for root canal disinfection includes photodynamic therapy (PDT). OBJECTIVE: To determine the antibacterial effect of photo-activated disinfection against Enterococcus faecalis in the irrigation of the root canals, through a literature review. MATERIALS AND METHODS: A qualitative study of an informative documentary type based on the review of documents, 40 articles were approved and reviewed. RESULTS: it can be shown that sodium hypochlorite and photo-activated therapy could be an effective complement for the 100% elimination of E. faecalis. CONCLUSIONS: photoactivation and sodium hypochlorite are effective for the elimination of E. faecalis, sodium hypochlorite is effective in eliminating the smear layer allowing a higher level of penetration depth in the dentinal tubules, the diode laser and Nd: YAG lasers are the types of laser most used in endodontics for the elimination of E. faecalis. KEY WORDS: E. faecalis, photo activation, photodynamic therapy.
