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.
