Abstract
Bacteria invading the pulp cause pulpal necrosis and the need for endodontic treatment. If bacteria are present after treatment, the root canal may fail. For the root canal to be successful in necrotic cases or retreating failing cases, the bacteria in the root canal walls must be removed and the canal sterilized with calcium hydroxide.
摘要
侵入牙髓的细菌会导致牙髓坏死，进而需要进行根管治疗。如果治疗后仍有细菌存在，根管治疗可能会失败。为了使根管治疗在坏死病例或失败病例的再治疗中取得成功，必须清除根管壁上的细菌，并用氢氧化钙对根管进行消毒。
