Comparison of Dentinal Defects Formation in Straight, Moderate and Severely Curved Canals by Three Distinctive Nickel Titanium Instruments: An in vitro Study [PDF]

Journal of Dentistry, 2023
Statement of the Problem: It is stated that engine-driven instruments might cause dentinal defects during root canal preparation. These defects might spread and progress into greater fractures or vertical root fracture.

The impact of clinical use on the torsional behavior of Reciproc and WaveOne instruments [PDF]

Journal of Applied Oral Science, 2016
The aim of this study was to assess the influence of clinical use, in vivo, on the torsional behavior of Reciproc and WaveOne instruments considering the possibility that they degraded with use.Diameter at each millimeter, pitch length, and area at 3 mm from the tip were determined for both types of instruments.

The Influence of a Glide Path on the Lifespan of WaveOne Reciprocating Files [PDF]

International Journal of Dental Sciences and Research, 2014
Background: Nickel-titanium instrument separation is a serious concern in endodontic therapy. A significant reduction of rotary instrument separation could be obtained when use of rotary file is anticipated by an initial manual preflaring and glide path. Normally this procedure is carried out by stainless steel hand files but new rotary nickel-titanium
