[Effects of fertilization on fine root diameter, root length and specific root length in Larix kaempferi plantation].

Ying yong sheng tai xue bao = The journal of applied ecology, 2007
With 16 years old Larix kaempfersoil plantation in the mountainous area of eastern Liaoning Province as test object, this paper studied the effects of fertilization on the fine root diameter, root length, and specific root length (SRL) of the first to fifth order roots. The results showed that with ascending root orders, the mean fine root diameter and

Complete control of root length preparation in endodontics

The Journal of the American Dental Association, 1967
Without a stop to control the depth of pene­ tration of the root canal file in the canal dur­ ing endodontic treatment, periapical irritation and an overfilled canal that may not be her­ metically sealed may result. The new stop discussed in this paper and the new point of reference, the floor of the pulp chamber, en­ able the dentist to use ...

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 ...

[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
