ABSTRACT Aim To evaluate the effects of a preflaring method on the determination of working length in the curved mesial canals of mandibular molars. Materials and methods Ninety mandibular molars with apical curvature of 30 to 40° were selected and randomly divided into two groups; each containing 45 teeth. In the first group, the initial instrumentation was performed with preflaring on the mesiobuccal canal (preflared group), and in the second group; the instrumentation was performed without preflaring on the mesiobuccal canal (nonpreflared group). A size 15 K-file was inserted in the mesiobuccal canals until the apical constriction could be felt by tactile sensation and a radiograph was taken to identify the distance between the file tip and radiographic apex. The location of the tip was classified as (a) within 1 mm of the radiographic apex, (b) more than 1 mm of the radiographic apex, or (c) overextended beyond the radiographic apex. The collected data was statistically analyzed and probability value was set to be ≤ 0.05. Results The file tip was significantly closer to the true working length in the canals with early preflaring compared to the canals without early preflaring (p < 0.005). In the preflared group; 75.5% of the cases had the file tip in location ‘a’, 13.3% in location ‘b’, and 11.1% in location ‘c’. In the nonpreflared group; 33.3% of the cases had the file tip in location ‘a’, 53.3% in location ‘b’ and 13.3% in location ‘c’. Conclusion Preflaring the coronal portion of curved canals greatly improved the access to the apical constriction, and thus enhanced correct working length determination. If the coronal portion of the curved canals is not preflared, the clinician cannot discern the accuracy of what they feel apically. Thus, preflaring is a highly recommended procedure especially in curved canals for better determination of correct working length. How to cite this article Iqbal A, Akbar I, AL-Omiri MK.

ABSTRACT AIM Working length determination in primary teeth endodontics using intra oral digital radiovisiography, and compare it with conventional method for accuracy. METHODOLOGY This in vivo study was conducted on 30 primary teeth which were indicated for pulpectomy in the patients of the age group of 5-11 years All experimental teeth had adequate remaining tooth structure for rubber dam isolation and radiographicaly visible canals. Endodontic treatment was required due to irreversible pulpitis or pulp necrosis. A standardized intraoral periapical radiograph of the tooth was taken using conventional method by paralleling technique. The distance between the source and the tooth, tooth and the films were standardized using X-ray positioning device. RESULT From the results obtained we can conclude that intraoral digital radiography methods of determining the root canal length in primary teeth can be considered reliable and safe in endodontic treatment of children. CONCLUSION The following conclusions were drawn from this present study Intraoral digital radiography also proved to be safest method in determining working length with significant reduction in radiation dosage. Hence this techniques can be safely used as an alternate to conventional radiographic method in determining working length in primary teeth.

Abstract The aim of this study was to evaluate in vivo the accuracy of the Raypex 5 and Root ZX electronic foramen locators (EFLs) in the presence of blood in the root canal space. Forty single-canal teeth scheduled for extraction were selected. Access cavity was prepared and coronal enlargement was carried out. Approximately two drops of blood were collected by finger prick and injected into the root canal space. The electronic working length (EWL) of each tooth by each device was established twice before (NB group) and after (WB group) injecting blood into the root canal. The tooth was extracted and the actual working length (AWL) was determined. Data were analyzed using McNemar's test. The accuracy rates of Raypex 5 and Root ZX within 0.5 mm in the NB group were 88.9% and 91.5%, with 83.3% and 86.2% in the WB group, respectively. There were no significant differences between the accuracy of each EFL in the two groups (p>0.05). Considering the NB and WB groups, there were no statistically significant differences in the accuracy of the EFLs (p>0.05). The presence of blood in the root canal space did not influence the accuracy of the EFLs.
