Tools of the trade: V-Taper 2H files

endo files

by Dr Simon Basha, Jetty Dental, Coffs Harbour, NSW

These files are heat-treated NiTi so they are flexible and follow the natural contours of the canal. The big advantage is that they’re much narrower towards the coronal portion, making them more conservative of dentine in the coronal parts of the canal.

What’s good about it

I primarily use these files in molar situations in order to preserve as much structure as possible and to reduce the risk of over-instrumentation and strip perforation. When treating molars, I find that calcified or narrower canals are very common. These files can also be used for larger canals but they’re not as efficient as the canal will need to be enlarged anyway.

The files have been designed to have plenty of fracture resistance to torsional loading, which is pretty much the same for all modern NiTi files. I dispose of them after each use.

I’ve been using them for about a year and while I’ve had really good results with molars, they’re useful in any case where you’re attempting to preserve radicular dentine in the coronal region. While they are less useful in large canals, they work extremely well in fine-rooted teeth with narrow canals.

What’s not so good

Obturation is more difficult than with some of the more common file systems. If you use the matched size with them, then the GP tends to sit a little bit shorter with pretty poor tug back. You need to step down your GP point size by a single size in order to get it all the way to length with adequate tug back.
