Lentulo spiral

Overview
A Lentulo spiral is a dental instrument used to properly distribute root canal sealer and cement evenly throughout the root canal system, as when performing endodontic therapy or a post and core cementation.

Maillefer’s Lentulo spiral, produced by Dentsply, is the only one licensed to use the Lentulo name; however, the term is generally used to refer to any of the various brands of root canal sealer and cement distributing spirals.
