Description
Özden and co-authors compare operator skill and four file systems for redoing root canal work in curved canals. Eighty acrylic blocks with a thirty-degree curve were treated first. Half went to a specialist and half to a trainee, each using four file brands.
The specialist finished faster, with a median time of 120 seconds versus 145. Problem rates did not differ clearly between operators. The ProTaper Universal system showed the lowest overall problem rate. The team also logged ledges, stray paths, and file damage such as unwinding or tip bending. Results guide training and tool choice for tricky canals.
