Description
Strand, Laegreid, and Fristad compare in 2026 four rinse needles for cleaning curved root canals in the lab. Cleaning the tip third of a canal is a hard part of root canal care, above all in curves. They used ten clear resin blocks with canals curved near thirty degrees.
Canals were filled with a blue dye and rinsed with plain water in a set dynamic way. Left over dye was measured by light absorption. A flexible plastic needle cleaned best, tied by a notched metal needle. A double vented metal needle left the most dye. Needle design shaped cleaning a great deal, a point dentists can use when they pick tools.
