“…Post‐instrumentation area was also greater in comparison with Lightspeed preparation (224), following ultrasonic preparation or rotary Canal Master preparation and equal to hand preparation using the stepback technique (49). A comparison of NiTi K‐files used in Balanced forces motion to current rotary instrument systems indicated similar shaping abilities (50).…”

“…Roane & Sabala (48) themselves and further studies (49, 50, 131, 185, 203, 207, 208, 213–217) described good results for the preparation of curved canals without or with only minimal straightening. However, others reported a relatively high incidence of procedural problems such as root perforations (218) or instrument fractures (219).…”

“… While currently available hand instruments have been used for almost a century, no definitive mode of use has emerged as the gold standard. However, the Balanced force technique (48) may be cited as such a gold standard for ex vivo and clinical studies (49–51). In the majority of experimental studies published in the literature only a small number of rotary systems or rotary techniques are investigated and compared.…”

Preparation of root canal systems includes both enlargement and shaping of the complex endodontic space together with its disinfection. A variety of instruments and techniques have been developed and described for this critical stage of root canal treatment. Although many reports on root canal preparation can be found in the literature, definitive scientific evidence on the quality and clinical appropriateness of different instruments and techniques remains elusive. To a large extent this is because of methodological problems, making comparisons among different investigations difficult if not impossible. The first section of this paper discusses the main problems with the methodology of research relating to root canal preparation while the remaining section critically reviews current endodontic instruments and shaping techniques.

“…The most ap]3ropriate canal shape restilted from a combination of a reaming motion (1 10° clockwise rotation) with size 15 and 20 instrtiments followed by the "balanced fbrcc" technique (180° clc)ck\vise rotation followed by a 180° counterclockwise rotation) with the subsequent instrument sizes tip to size 35 (23). Tlie canals were not straightened and material was removed from the inner curve of the canal except in some instances in the f mm closest to the a In accordance with otir results, several atithors have reported better instrtimeiUatic:)n of curved canals with the "balanced force-" techniqtie as compared to the "step-back" technicitie (24,25).…”

-In an assessment of the usefulness of diffcrcnl root canal instruments, two aspects arc of particular interest fbr the endodontist: the cutting efficiency of the instrunieiUs and their ability to enlarge cun^ed canals without undesirable changes of the canal shape such as the fbnriation of zips and elbows. This review pajUM" is based on own investigations on the cutting elliciency and iiistrumentaUon of curved canals. Addilionally, two parameters which arc described in ISO 3630-1, resistance to bending and resistance to fracture, are discussed. With regard to cutting eflicicncy in rotaiy motion, flexible stainless steel reamers and K-filcs clearly display the best results and are superior to conventional stainless steel as well as titanium-based reamers and K-files. Regarding cutting efficiency in linear motion, stainless steel Hedstrom files made by certain manufacturers are significantly superior to stainless steel and titanium-based Hedstrom files of other brands. Flexible stainless steel instruments with modified noncutting tips clearly produce the best canal shape in curved canals. With only rare exceptions, all the instruments tested fulfilled the requirements of the ISO standard concerning resistance to fracture and resistance to bending.
