[Management of apicectomy and root canal obturation completed one time under direct vision].

Abstract

PURPOSE:

To evaluate the clinical effect of apicectomy and root canal obturation completed one time under direct vision on chronic periapical periodontitis of anterior teeth.

METHODS:

34 cases(40 teeth) with RCT failing or larger periodontal lesion, which couldn't be cured depending on RCT only, were chosen for this clinical study. They were randomly divided into two groups with 20 teeth in each group. Root canal obturation was done after apicectomy under direct vision(group A),or apicectomy was done after RCT(group B).The time of filling process, the ratio of postobturation pain, the obturation quality and short-term efficiency of the treatment were assessed. The data were separately subjected to t test, Chi-square test, Mann-Whitney U test with SPSS12.0 software package.

RESULTS:

The time of filling process in group A was significantly less than group B (P<0.05); No statistically significant difference was found between group A and group B in the ratio of postobturation pain, obturation quality and clinical therapeutic efficiency.

CONCLUSIONS:

The method of apicectomy and root canal obturation completed one time under direct vision is rapid, simple and effective in treating chronic periapical periodontitis of anterior teeth.The short-term clinical therapeutic efficiency is similar to that of apicectomy done after RCT.
