Advancements in Obturating Materials for Pulpectomy of Primary Teeth: A Comprehensive Review

Abstract A healthy, intact primary tooth acts as the most effective and natural “space maintainer”. Primary teeth preserve arch length and function until physiological exfoliation. So, pulpectomy is a crucial treatment for maintaining primary teeth affected by irreversible pulpitis or having a necrosed pulp. Correct choice of obturating material is of paramount importance for the success of pulpectomized teeth. The obturating material must be biocompatible, resorbable at a rate similar to root resorption, it should be non-toxic and radiopaque. This comprehensive review aims to provide an updated overview of the advancements in obturating materials specifically developed or investigated for pulpectomy in primary teeth.
