Özet

AİM:

The aim of this study was to evaluate the outcome of single-visit and 2-visit non-surgical root canal retreatments of teeth with asymptomatic periapical lesions and the influence of various predictors on treatment outcome.

SUMMARY

A total of of 40 patients with asymptomatic root canal-treated teeth in need of retreatment were randomly divided into 2 groups (n=20). Patients in group 1 were treated in a single visit. Patients in group 2 were treated in two visits using calcium hydroxide as an intracanal medicament for one week. For each included tooth the gender of the patient, length of the root canal filling and restoration type were recorded. Treatment outcomes were assessed radiographically according to Periapical Index(PAI). One tooth was lost to follow-up, remaining 39 teeth assessed by two calibrated examiners for outcome as healed (periapical index score-PAI≤2; no signs and symptoms) or diseased (presence of apical periodontitis-PAI >2; signs or symptoms). The follow-up period was 12-24 months in both groups and the last follow-up data were analysed using the chi-square tests and Fisher tests. The Kaplan-Meier analyses were used to analyse the cumulative survival time. All tests were performed at a significance level of 0.05.

Thirty-nine of the 40 patients were available for final analysis. In one-visit group, 14 (70%) teeth considered as healed, 6 teeth considered as diseased (30%). In two-visit group, one tooth was lost to follow-up and 15 (79%) teeth considered as healed, and 4 teeth (21%) considered as diseased. Mean observation time for one-visit group was 15,9 months and two-visit group was 14,8 months. There were no significant differences in success and survival rate among the groups after the follow-up periods (p>0.05). Gender did not have a significant impact on treatment outcome (p>0.05). Length of root canal filling and restoration type had significant effect on the retreatment outcome (p<0.05).

KEY LEARNING POINTS

·             This study showed that one-visit and two-visit retreatment had similar treatment outcome.

·             Due to the advantage of decreased treatment time, one-visit retreatment appears as an efficient alternative to two-visit retreatment in asymptomatic teeth with periapical lesions.
