皆さんこんにちは。

ようやく外も涼しくなってきてましたね。

天気も良いので今年の秋は勉強だけでなく、

スポーツの秋にもしたいものです。

さて、今回の論文は嫌気性放線菌であるActinomyces

israeliiの根管感染についてです。

A case report is presented of a periapical lesion that was impossible to treat successfully by conventional endodontic therapy. A strain of A israelii was repeatedly isolated, in pure culture, from bacteriologic specimens collected during treatment. There was uncomplicated healing and good bone regeneration after the root of the tooth was filled and periapical surgery was performed. No antibiotics were given.

The current case of periapical actinomycotic infection, and those diagnosed earlier by histologic technique, indicate that infections with Actinomyces are a challenge to successful conventional endodontic therapy and that supporting periapical surgery is necessary for the efficient elimination of the infection.

つまり、A israeliiは根尖孔外に持続的に感染する為、

通常の根管治療では除去が難しく、

外科的歯内療法が必要になってくる場合もあるということです。
