Comparison Of Radiovisiography And Apex Locator With The Conventional Method In Root Canal Length Determination Of Primary Teeth
Journal Title: National Journal of Medical and Dental Research - Year 2017, Vol 6, Issue 1
Abstract
Purpose: The purpose of this study was to assess whether Radiovisiography and Apex locator can be used as an alternative to Conventional method of radiography for determination of working length in pulpectomy of primary molars. Methods: This in vivo study was conducted on 50 primary teeth indicated for pulpectomy. A standardized periapical radiograph was taken using conventional method by paralleling technique and E speed film. Measurement from digital radiography was obtained by modifying the method to minimize overprediction. Fourth generation apex locator, Ipex was used for the estimation of working length. The measurements were then compared with the conventional method of root canal measurement technique for accuracy. Results: The mean values between Radiovisiography and conventional method showed non-significant p value of 0.851. The pearson correlation between Radiovisiography and conventional method (0.911) was more than correlation between apex locator and conventional method (0.862). RVG showed over prediction of working length while Apex locator showed shortest working length among the three methods. Conclusion: Radiovisiography showed more correlation with conventional method than apex locator. Inspite of giving short working length, apex locator is recommended in pediatric endodontics because of the presence of physiologic resorption. Therefore, apex locator can be recommended in conjunction with RVG to accurately determine the working length in primary teeth.
