Electronic determination of root canal length

Journal of Endodontics, 1980
Root canal length was measured in an experimental model composed of the severed halves of porcine mandibles, using an electronic device for locating the apical foramen. The measurements, each taken independently by two or three observers, were compared with radiographic working length determinations, and with direct visual measurements made after the ...

Seasonal dynamics of fine root biomass, root length density, specific root length, and soil resource availability in a Larix gmelinii plantation

Frontiers of Biology in China, 2006
Fine root turnover is a major pathway for carbon and nutrient cycling in terrestrial ecosystems and is most likely sensitive to many global change factors. Despite the importance of fine root turnover in plant C allocation and nutrient cycling dynamics and the tremendous research efforts in the past, our understanding of it remains limited.

[Length measurement of the root canal].

Deutsche zahnarztliche Zeitschrift, 1977
Twenty-five years of experience in the field of length measurements of the root canal are summarized. It must be concluded that there is no absolutely accurate method to measure the length of the root canal in vivo because of the specific anatomic conditions and the sources or error inherent in all methods.

[Electronic determination of the length of the root canal].

Revue belge de medecine dentaire, 2003
The endpoint of an endodontic treatment must be situated at the cemen-to-dentinal junction to preserve the biological potential of the periapical area and to realize a complete disinfection of the principal root canal system. Thus, the determination of working length is a crucial factor in endodontic therapy. The conventional radiographic method cannot
