Stainless Steel

which file types are sterilized and come with blister packs recommended for single use?

Single use

Endodontic files exhibit signs of wear during normal use, which increases dramatically with multiple use. _______ therefore reduces the risk of file breakage and thus increases patient safety.

cutting efficiency

Research has shown that using files for multiple cases reduces their __________ and therefore leads to a poorer performance. ___________ is therefore achieved when a new instrument is used for each patient.

bacteria and tissue remnants

Research shows that certain __________may remain on the instrument, post-sterilization. Single patient use will therefore eliminate such risk.

PROTAPER NEXT

features a patented off-center, rectangular core that adds greater strength as the file tracks down the canal

ProTaper Universal SX

•recommended for radicular access prior to canal shaping.

•Single length - 19 mm

ProGlider Rotary Glide Path File

•The root canal path is lined with twists & curves that require flexibility in a file to create a predictable glide path. This file cuts this path with precision, creating a free fall to the apex for shaping file systems

Friction Grip Round

•Come in Standard Length and Surgical Length

•Used in high speed handpiece for initial access preparation

Endo-Z

•Used for finishing internal walls of access preparation

•Long, tapered bur creates a funnel shape for easier access in the pulp chamber

•9 mm cutting surface length with a non-cutting tip

Gates Glidden

•You will use #2 and 3

•Comes in sizes 1-6

•Enlarges the coronal portion of the canal for bulk removal of tooth structure

•Used for orifice shaping prior to instrumentation
