Abstract

Purpose: To investigate the effect of different root canal filling materials on the change of failure of the endodontic treatment of necrotic primary teeth.

Methods: A literature search was carried out in PubMed/MEDLINE, CENTRAL, Scopus databases, and grey literature up to July 2022 selecting randomised clinical trials related to research question. Two reviewers independently selected the studies, extracted the data, and assessed the bias risk. Root canal filling materials were grouped according to the main component [iodoform (IOD), calcium hydroxide (CAOH), zinc oxide (ZO) or mix (IOD plus CAOH plus ZO) pastes]. Pairwise and network meta-analyses using the mixed treatment comparisons method were performed to compare the number of events (failure) among treatments. Odds ratio and 95% confidence intervals (CI) for calculated. Post-probabilities among treatments were also calculated and interpreted.

Results: From 1186 potentially relevant studies, 17 were selected for full-text analysis, and 7 were included in the meta-analysis, totalizing 263 teeth. In the direct evidence, ZO pastes resulted in a higher chance of failure than IOD pastes (OR 7.07 95% CI 1.02, 62.59). In the indirect evidence, there was no difference between the materials. The IOD pastes presented a high probability (81%) of being the treatment associated to lowest number of failures among all treatments. The CAOH pastes presented the highest probability of being the worst option. Studies showed high bias risk.

Conclusion: There is currently no scientific evidence of the superiority of any one root canal filling material for endodontic treatment of necrotic primary teeth.
