Canal Prep Gels & Lubricants

About canal prep gels and lubricants

Canal prep gels come as a gel rather than a solution: EDTA is supplied in both forms, which differ in flow and in how they meet the canal wall. A solution spreads through the canal readily, while a gel keeps contact with the dentine over longer periods.

Thick enough to stay where it is put, rather than running through the canal. One study reported the solution forms diffusing better than the viscous gels.
