Comparison of digital radiography and apex locator with the conventional method in root length determination of primary teeth

AimsThe purpose of this study was to evaluate the accuracy of a new-generation electronic apex locator (iPex) to determine working length in primary teeth with or without root resorption as compared with the conventional radiographic method.Materials and methodsA sample of 30 primary posterior teeth which are indicated for pulpectomy were selected for the study. After obtaining the informed consent from the parents, local anesthesia was administered. Access cavity was prepared with no.10 round bur. Initial exploration of the canals was done with no.10 K-file. Pulp was extirpated with a barbed broach followed by thorough irrigation of the canals with 0.9% saline. Initially, working length was obtained with iPex (new-generation by Nakanishi International) apex locator using no.10 K-file, which was then compared with conventional radiographic method (Ingle’s method).ResultsA total of 65 canals were available for the measurement. The data were analyzed using Statistical Analysis system and t-tests were carried out. There was no statistically significant difference found when using iPex apex locator for working length determination as compared with that of conventional radiographic method (p = 0.511).ConclusionWorking length determined by iPex apex locator is comparable with that of conventional radiographic method, hence, can be used as an alternative in determining the working length of primary teeth.How to cite this articleBhat KV, Shetty P, Anandakrishna L.

Aims:The aim of this clinical study was to evaluate the clinical accuracy of two electronic apex locators (EALs).Materials and Methods:A total of 120 patients with 283 roots were randomized into three groups including, traditional radiographic method, EAL (Root ZX mini), and apex locating endodontic motor (VDW Gold) for working length (WL) determination. Root canals were instrumented to a size ProTaper F3 nickel titanium file. The obturation quality of matched tapered master cone (ProTaper F3) was determined for the accuracy of WL.Statistical Analysis Used:Descriptive statistics were expressed as numbers and percentages. Pearson Chi-square test was used to determine for differences between groups. P < 0.05 was considered statistically significant for all tests.Results:There was no statistically significant difference between the three tested groups (P = 0.894).Conclusions:The success of both apex locators was similar to the radiographic WL determination technique.

“…The terms root canal length (RCL) and working length (WL) have been used (Neena et al, 2011). However, the former refers to actual measurements made with the direct method or the estimated measure obtained from an initial radiograph (Mello-Moura et al, 2010), whereas the latter refers to the length at which chemo-mechanical preparation and sealing should be performed, usually reducing 1 mm from the RCL (Nelson-Filho et al, 2011).…”

“…Clinically, RCL estimates have been conventionally performed by pre-operative radiographic evaluation (Rodd et al, 2006;Neena et al, 2011;Nelson-Filho et al, 2011;Chougule, Padmanabhan, & Mandal, 2012;Saritha et al, 2012;Ahmad & Pani, 2015). However, anatomical variation in the apical foramen as well as superimposition of structures and periapical lesions may hinder appropriate RCL determination (Haffner, Folcwaczny, Galler, & Hicckel, 2005).…”

Background: The root canal length (RCL) estimates is an essential step for total endodontic therapy procedures. The aim of this study was to measure the RCL in a sample of extracted primary anterior teeth and compare the data obtained with the literature for educational and clinical purposes. Materials and methods: Seventy extracted primary anterior upper and lower teeth were selected according to the following inclusion criteria: absence of root resorption and/or internal root canal anatomy complications, and no previous root canal manipulation. The teeth were assigned to six groups: upper central incisors (UCI; n = 15), upper lateral incisors (ULI; n = 13), upper canines (UC; n = 20), lower central incisors (LCI; n = 6), lower lateral incisors (LLI; n = 3), and lower canines (LC; n = 13). RCL was measured by the direct method after insertion of a #15 K-file with a silicone stopper in the root canal until the root apex and measuring with a millimetre rule. Results: Mean RCL values (mm) obtained were UCI = 14.33 ± 1.69; ULI = 14.00 ± 1.63; UC = 16.07 ± 2.43; LCI = 15.41 ± 3.20; LLI = 15.00 ± 1.73; and LC = 16.38 ± 1.51. Conclusions: The RCL direct measurement method and the results obtained were in accordance with the literature reports and can be useful for educational purposes aiming at knowledge of dental anatomy and the clinical determination of root canal treatment viability and treatment of primary teeth, as RCL is one of the parameters for the indication/contra-indication of this therapy.
