“…It measures the degree of the curvature in order to categorize root canals as straight (51 curvature or less), moderately or severely curved (4201). More advanced techniques (115)(116)(117)(118)(119) aim to determine degree and radius as well as length and location of the curve(s), since all of these factors may influence the treatment/preparation outcome.…”

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.

“…Precise knowledge about the root canal morphology is essential, both for root canal filling and for possible placement of post systems (7,9). Different studies and various techniques have examined the configuration of root canal systems (1,13), the root canal path (15) morphological variations (2,9,25) as well as the angles of root canal curvatures (7,18,22). Despite root canal treatment possibilities, such as electronic working length determination, little data exists concerning distances and localization of root curvatures to be used as a guide for the actual straight distance of the root canal when considering post insertion.…”

“…Measurement ofthe thickness of dentine wall and canal diameter were only possihle in the X y axes which may not he a true reflection of the situation in a curved canal. Mayo et al (1986) and Gullickson & Montgomery (1987) have proposed radiographic analysis hy a computerized video image processing program. This method was used to obtain root canal volume, cross-section of the root at any level from the apex and line drawings representing the cut surface.…”

This study introduced an in vitro model which was designed to observe the effects of instrumentation on the shape of curved root canals. The model may be accurately rotated through 90 degrees allowing reproducible radiographs to be taken from two different angles. The root canals were filled with a radiopaque contrast medium before radiographs were taken. Two-dimensional evaluation of the shape of the root canals, before and after preparation was made on enlarged photographic prints obtained from the radiographs. A custom-made grid was used as a guide for measurement and accurate transfer from the pre- to postpreparation prints. Reproducibility of measurement was within 4 per cent. This method is feasible for quantitative comparison of the effect of instrumentation on the shape of root canals.
