The Effect of Failure Root Canal Treatment on the Tooth: A Systematic Review

Abstract

The failure of root canal treatment occurs due to lack of standards or aspects of procedure were not followed accurately. Root canal treatment’s failure can be justified by response ratio of teeth and procedural errors that limits the intracanal endodontic infection, but not control it properly as preventive measure. Although there was very little evidence regarding the predictive factors for tooth preservation, effects of failure of root canal system and tooth survival was investigated. Very few studies have been conducted to evaluate the clinical outcomes of failure of root canal treatment on tooth survival. Therefore, we will aim to design a systematic review to evaluate clinical outcomes of failure of root canal treatment on tooth survival. We conducted a systematic review by following “Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)” guidelines related to title which was “The effect of failure root canal treatment on the tooth” according to study aims. The study selection criteria (as including both inclusion and exclusion criteria) were designed for screening and selection of collected data in recent systematic review. For recent systematic review, we collected about 67 studies related to the effect of failure root canal treatment on the tooth through searching from above mentioned databases About 7 out of remaining papers were up to the standard and met the above-mentioned criteria. The above included 7 studies were relevant to study aims and evaluated the effects of failed toot treatments or root canal treatment (RCT) on tooth survival, tooth health and safety. All included studies coded the major effects of failure root canal treatment as the swelling, (Topçuoğlu & Topçuoğlu, 2017 & Ulin et al., 2020) prospective pain, (Ballal et al., 2020, Wang et al., 2010 & inflammation, (Verma et al., 2019) and microbial attack (Chen et al., 2017 & Jordan et al., 2014) intensity. However, all studies have evaluated different root canal treatment with different non-surgical treatments. Overall, the clinical effects of failure of root canal treatment are severe and should be overcome with retreatment.
