Prevention of root canal treatment of infected

The many factors that lead to root canal treatment failure, the root canal re-infection is a very important factor, and easily ignored by clinicians. Open the pulp, the beginning canal preparatory to the completion of root canal filling, dentistry, and surgery should always have to prevent the awareness of the root canal infection and reinjection, and the corresponding measures.

First, the use of rubber dam is a very important tool. It can effectively avoid the surgical procedure, the oral environment on the recontamination of the root canal system. Of course, the benefit of using a rubber dam is far more than this also prevention devices fall into the mouth or swallowing aspiration. To protect the adjacent soft tissue, to avoid being accidentally scratched or drugs burns, repeat do not do this. If subject to conditions, it can not do a root canal treatment carried out under the protection of the rubber dam. Then maybe focus on whatever things will be more practical significance. Began to root canal treatment, pre-need to do is to completely remove all caries detritus. Such a request has two meanings: first, before you come into contact with the root canal orifices, anywhere on the crown are not there in caries detritus, even if it is not directly related to opening the chamber whole, far away; do root canal therapy, while retaining the original backfill or full crown restoration, this approach should not be dental equipment encouraged.

Second, usually the apical 4 mm of filling closed root canal filling. This does not mean you can ignore the tight filling of the root canal. Root canal the previous paragraph filling internal voids, or root filling material and root canal wall is not close, or destruction of a closed root canal prosthesis, are prone to root canal recontamination. Thereby increasing the risk of failure of root canal treatment.

At the same time, the poor crown fillings or temporary closure of the sealing material can lead to root canal recontamination. The teeth in the environment of saliva for Extraction method and steps a long time, any material of any technology can not fundamentally avoid repair body micro leakage of root canal moment suffering from threats of pollution. Surgery tooth after root canal treatment, rehabilitation design, you must give full consideration to the appropriate choice of repair time, repair materials and repair techniques, and prevention to reduce the chance of reinjection of the root canal.
