“…The results of the present study compared with those of many other previous studies. [15][16][17][18][19][20][21] Seidberg et al (1975), 15 in a clinical study compared the sonoexplorer with digital tactile senses in determining the working length of the root canals, and found that the digital tactile sense was more satisfactory than the sonoexplorer.…”

Objective: The purpose of this in vivo study was to compare the ability of digital tactile, digital radiographic and electronic methods to determine reliability in locating the apical constriction. Materials and methods:Informed consent was obtained from patients scheduled for orthodontic extraction. The teeth were anesthetized, isolated and accessed. The canals were negotiated, pulp chamber and canals were irrigated and pulp was extirpated. The working length was then evaluated for each canal by digital tactile sensation, an electronic apex locator (The Root ZX) and digital radiography. The readings were then compared with post-extraction working length measurements. Results:The percentage accuracy indicated that EAL method (Root ZX) shows maximum accuracy, i.e. 99.85% and digital tactile and digital radiographic method (DDR) showed 98.20 and 97.90% accuracy respectively.Clinical significance: Hence, it can be concluded that the EAL method (Root ZX) produced most reliable results for determining the accurate working length.

“…Nevertheless, many authors prefer X-rays and tactile sense possible to locate the apical constriction or root canal length accurately [14] [15]. On the other hand, Pratten and McDonald [16] suggested that the true apex can be determined using a calibrated apex locator even where radiography and tactile determination are lacking. This corroborates with the study of Mutu Shanmugaraji et al 2007 [17] indicating that the fifthgeneration apex locator showed the highest accuracy and the highest reliability (86.7%) compared to the radiograph (76.6%) and tactile sensation (33.3%).…”

Background: There is paucity of literature on the determination of the root canal length of Bantu subjects in dental professional practicing in Africa and Democratic Republic of Congo in particular. Aims: The aim of the present study was to determine the root canal length of teeth of Bantu patients extracts attending the Teaching Hospital of Kinshasa University. Methods and Material: Prospective cross-sectional study was carried out in the service of Conservative Dentistry. The patients suffering with pulpitis of permanent teeth which were selected for root canal treatment during the period of January 2014 to December 2016 were included. All patients whose main root canals were inaccessible, teeth carrying prosthesis, teeth with large coronal decay, teeth having periapical periodontitis, supernumerary teeth, wisdom and primary teeth were excluded. Results: The upper canines presented some significant longer canals compared to the lower canine (23.4 ± 2.3 mm and 21.6 ± 1.8 mm). Palatal canals of the first and second molar were respectively longer as compared to the superior teeth canals (21.5 ± 1 mm, 21.3 ± 2 mm). The distal canals of the first and second molar were the longest in the mandibular arch respectively measuring 20.7 ± 2.0 mm and 21.5 ± 1.7 mm. Conclusion: Data obtained from Bantu patients show slightly shorter roots compared to How to cite this paper:

“…13 Both in vitro and in vivo have confirmed the accuracy of apex locators. [14][15][16] But the use of apex locators along with a pre-and postoperative digital radiograph is advised in most of the circumstances. This study aims to compare the accuracy of measurements obtained through these methods in comparison with the actual working length estimated from extracted tooth.…”
