“…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).…”

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.

“…This risk may be reduced by performing coronal enlargement and by creating a manual and/or mechanical glide path before using NiTi rotary instrumentation [8, 15, 16]. Following this initial shaping, using the Protaper System in a different protocol from that recommended by the manufacturer was able to promote a better overall result in cases of constricted canals.…”

Negotiation of constricted canals can be a challenge during endodontic treatment. Over the years, several strategies have been presented in order to overcome the difficulties imposed by this anatomical feature. This paper presents three cases using a different protocol from that recommended by the manufacturer of the Protaper System in order to facilitate the negotiation of constricted canals. These cases suggest that the modified protocol shown is able to perform the shaping process with less resistance, reducing the risk of instrument separation and performing an effective process to reach the apical thirds in constricted canals.
