Abstract

Abstract:

Objective

This retrospective study aims to evaluate the clinical outcome of root canal treatment filling with single-cone technique and iRoot SP sealer and to identify factors associated with success or failure.

Methods

There are 110 teeth with a minimum of 1-year recall included in this retrospective study, which received root canal therapy and were filled with single-cone technique and iRoot SP sealer in the hospital of Stomatology affliated to Sun Yat-sen University from 2014 to 2018. According to the clinical examination and radiographic examination at recall, the outcome of the treated teeth was classified as success and failure. For statistical analysis, chi-square test with Yate′s correction and Fisher′s exact test were used to identify which prognostic factors would influence the clinical outcome of the treated teeth. Eight prognostic factors such as the presence of periapical lesion, size of periapical lesion and extruding sealer were evaluated in this study.

Results

The overall success rate of the 110 treated teeth included in our study was 95.5%. The success rate of 83 treated teeth with periapical lesions was 96.4%, and 68.7% were healed. The success rate of 27 treated teeth without periapical lesions was 92.6%. There was no significant difference found in success between teeth with and without periapical lesions (χ² = 0.084, P = 0.772) . The successful rate of the 53 treated teeth with periapical lesions less than or equal to 5 mm in diameter, was 98.1%. There were 30 teeth with periapical lesions lager than 5 mm in diameter and the success rate was 93.3%. No statistical difference was noted between the two groups (χ² = 0.259, P = 0.611) . Besides, Forty-four treated teeth exhibited postoperative sealer extrusion, the success rate of which was 97.7%. No significant difference was found in success between the presence or absence of postoperative sealer extrusion (χ² = 0.218, P = 0.640) .

Conclusion

Single-cone obturation with iRoot SP sealer is a viable root canal filling technique.

Key words: Root canal obturation, Treatment outcome, Single-cone obturation, iRoot SP
