Effectiveness of iodoform-based filling materials in root canal treatment of deciduous teeth: a systematic review and meta-analysis.

Iodoform-based filling materials showed better clinical and radiographic performance when compared to non-iodoform-based filling materials in the short term, and similar performance in the long term. However, most of the studies exhibited unclear or high risk of bias and the overall certainty of the evidence ranged from low to very low. Therefore, new randomized clinical trials must be accomplished to corroborate this conclusion.
