Obturation of Primary Teeth: Time to Redefine Objectives and Techniques

Obturation creates a seal along the root canal, preventing fluid movement and blocking potential entry points for bacteria found between the periodontal tissues and the root canal system. Several techniques are used for obturating primary tooth canals, including tuberculin syringe, disposable injection technique, manual incremental lateral condensation, Jiffy tubes, Navi-tip, lentulo spiral (hand-held or rotary), past inject, and endodontic pressure syringe. These methods only prioritize cost-effectiveness, ease of use, and material control for successful outcomes. However, to date, no classification has been proposed for the method of material placement in the root canal. Thus, this article highlights the obturating methods in the direction of placement of material and proposes a newer classification for the criteria of obturation, which can significantly influence the success rate of the endodontic therapy.
