Sekonder endodontik enfeksiyonlarda, enterococcus faecalis'in rolü ve tedavisi

Kök kanal dolgulu dişlerde %29den %70e değişen oranda E. faecalis görülme sıklığı vardır. Yüksek alkali pH ve tuz konsantrasyonu içeren sert ortamlarda bile hayatta kalabi- lir. Litik enzimler, cytolsin, agregasyon maddeleri, fenomen, lipoteyik asit gibi E. faecalis belirli virulans faktörleri içerir. Uygun bir aseptik teknik kullanma, apikal preparasyon boyutunu artırma, sodyum hipoklorit ve %2lik klorheksidin irrigasyon solüsyonlarının ilave edilmesi, E. Faecalisi yok etmede en etkili yöntemlerdir. Medikaman ve dolgu patının kullanılması başarısız kök kanal tedavilerinin yenilenmesi sürecinde E.faecalisi tamamen yok etmede önemli rol oynar. Bu çalışma E. Faecalisi ve dirençli endodontik enfek- siyonlara neden olan mekanizmasını daha iyi anlamamıza yardım etmektedir.

Role and treatment of the enterococcus faecalisin secondary endodontic ınfections

E. faecalis has been frequently found in root canal-treated teeth in prevalence values ranging from 29% to 70% of the cases. E. faecalis survive very harsh environments including extreme alkaline pH and salt concentrations. E. faecalis possesses certain virulence factors including lytic enzymes, cytolysin, aggregation substance, pheromones, and lipoteichoic acid. Currently, use of good aseptic technique, increased apical preparation sizes, and inclusion of sodium hypochlorite and 2% chlorhexidine irrigants are the most effective methods to eliminate E. faecalis. Recent study has helped us better understand E. faecalis and the mechanisms that enable it to cause persistent endodontic infections.
