Introduction: The radiographic method is widely used to calculate the working length (CT). However, it presents limitations that, to overcome them, apical electronic locators (LEAs) were developed to allow greater accuracy and reliability in determining the CT. Objective: The present study aims to perform an integrative systematic review and gather the available scientific evidence on the method that allows greater accuracy in determining the CT between the radiographic method and the electronic localisation method (LEA). Materials and Methods: The literature search was performed on the PubMed platform using keywords combined through the Boolean operator AND as follows: ("endodontics" AND "electronic apex locator" AND "radiographic measurement") and ("endodontics" AND "electronic apex locator" AND "radiographic measurement" AND "odontometry"). Results: 68 articles reporting comparative studies performed between the methods, radiographic and LEA, were identified. Eleven studies were included, of which, in some cases, LEAs showed better results than non-digital periapical radiographs. The studies indicate that although there are differences between the two methods, with greater accuracy in determining LEA, the differences did not prove to be statistically significant. In the presence of irrigating solutions, sodium hypochlorite revealed more significant discrepancies in CT determination with the LEA method. Conclusion: The two methods, radiographic and LEA, should be used in association since each has particularities that present more significant benefits enhancing the success of endodontic treatment and a better and more complete treatment for patients.

Aim:Compare the measurement of working length with three different methods manual tactile sensation, digital radiography and Mutidetector computed tomography(MDCT).Materials and Method:40 human premolar extracted for orthodontic purpose were selected. Teeth were store in sodium chloride (0.9%) during the study. Access cavity was prepared and canal patency was seen with no 10 file in each tooth. Manually no 15 K file was inserted from access cavity until the tip was visible at the foramen, a silicon stopper was adjusted to the corresponding buccal cusp tip and the root canal length was measured. After that in each tooth with no-15 K file inserted from access cavity with stop at tip of buccal cusp until tip appear at foramen and x-ray was taken with digital radiograph (RVG,Satelac) and canal length was measured. After that all teeth are mounted in wax block,MDCT scan was done and in the scan images of teeth, root canal length is measured from buccal cusp tip to root end. After taking measurement of working length with all three methods and the data was stastically analyzed with One Way Analysis of variance (ANOVA) followed by Turkey's Test.Results:ANOVA and turkeys test showed that there was no significant difference in the measurements by the three procedures (p>0.05).Conclusion:Working length measurement with MDCT scan and other two conventional methods does not show significant difference in measurement. Use of newer 3D imaging technique is useful in root canal treatment for measuring working length.

Background: Determination of appropriate or exact working length measurement with radiovisiography (RVG) during root canal treatment (RCT) is an essential for the long-term success. As, there are several controversies with the distortion of RVG image in assessing the working tooth length (WTL) during RCT compared to actual tooth length (ATL). So, this study was aimed to assess the frequency of distortion of radiovisiographical tooth length (RTL) compared to actual tooth length (ATL). Methods: An analytical (in-vivo and in-vitro) study was conducted at Department of Conservative Dentistry and Endodontics, BSMMU. The patient indicated for extraction purpose of orthodontic treatment was considered as the study population. Human premolar teeth (n=20) were selected as study sample by purposive sampling technique which met the inclusion and exclusion criteria. The RTL measurements were carried out with RVG images before and after tooth extraction (in-vivo and in-vitro setting). Then the ATL measurements of extracted tooth samples were carried out with both Inch Architectural Scale Ruler and Endodontic Ruler individually three concordant times. Statistical analysis: The data was analyzed using T test and presented in frequency and percentages with tables. Results: For 95% of study samples, the differences from actual and radiovisiographical tooth length were <0.5 mm. Total 19 tooth samples (out of 20) showed acceptable level of coincidence except one sample showed non-acceptable level of coincidence. There was no sample revealed exact level of coincidence. There was a significant difference between the distortion category; yes (95%)/ no (5%) (P 0.001). The radiovisiological tooth lengths among all samples were same in both in-vivo and in-vitro setting. Study results also revealed the average distortion of RTL to ATL was 2.61±0.97 mm when RVG was done without using RVG sensor positioner. Conclusion: RVG tooth length images exhibited no distortion with the exact anatomical tooth lengths when the RTL was carried out with RVG sensor positioner. It’s recommended that to overcome the RVG image distortion, the RTL measurement ought to be carried out with RVG sensor positioner allowing RVG sensor/film parallel to long axis of tooth; RVG beam position perpendicular (900) to long axis of tooth.
