Late failure of root canal therapy: a diagnostic and treatment planning challenge. Case report.

This report describes a case in which failure of conventional root canal therapy presented 17 years following initial treatment. The apical pathology was curetted, the tooth root resected and a root-end filling placed. The possible reasons for failure of the initial orthograde root canal therapy are discussed with the conclusion that the cause may not have been addressed fully by surgical intervention. The case highlights the challenge facing clinicians when assessing failed root fillings, not only in determining the exact cause of failure but deciding the appropriate treatment for the individual tooth and patient.

[The effect of left bacteria in the root canal on prognosis of the root canal therapy].

OBJECTIVE: To study the effect of the left bacteria on the root canal therapy. METHODS: 50 single-rooted teeth with chronic apical periodontitis were divided into two groups, one was instrumented with step-back technique and 2.5%NaOCl ultrasonic irrigation for 3 min, then filled with Thermafil. Samples were taken after instrumentation to culture. The other was treated with traditional RCT at three visits. RESULTS: In 24 months the apical radiolucency were greatly reduced in all cases. There weren't significant relationship among the postoperative pain and the left bacteria, the degree of the obturation or the pre-operative symptoms (P > 0.05). CONCLUSION: The effect of left bacteria in root canal filled with Thermafil wasn't observed.

[Root canal therapy opportunity in replanted teeth due to injury.].

PURPOSE: To investigate the opportunity of different root canal therapies in replantation of tooth due to injury. METHODS: 49 cases with teeth luxation were randomly divided into three groups. In group A, the pulp was removed before replanted, and calcium hydroxide was filled in root canals and condensated routinely after half a year. In group B, the pulp was removed one week after being replanted. In group C, the pulp was removed until pulp disease. RESULTS: The effect of group A(81.25%) and B (94.44%) was better than group C (53.33%), P<0.05. And the effect of group A and B was similar. CONCLUSION: It's an ideal method to replant luxated tooth within 3 hours with removal of pulp tissue, root canal filling with calcium hydroxide one week after replantation of tooth and condensated routine root canal therapy after half a year.

[Complications in root canal therapy].

Several factors prior to, during and after treatment may complicate root canal therapy. In this article several of these complications are discussed together with their possible solutions to these problems.
