ABSTRACT
OBJECTIVE: To compare the accuracy of digital radiography method for root canal working length determination compared withactual root canal length in patients presenting at Isra University Hospital Hyderabad.
STUDY DESIGN: A Cross sectional comparative study
PLACE AND DURATION: At Operative Department/College of Dentistry Isra University, Hyderabad. Study duration was from 13thAugust 2012 to 13th August 2013.
METHODOLOGY: A total fifty patients of either gender who were advised extractions of teeth for orthodontics or any other reasonswere selected. The access opening was performed, after which a stainless steel wire was inserted in the canal. The Digora system andaid of a device were used and all digital radiographs were taken by the paralleling technique. The radiographic images were sent andsaved in a computer and working length was calibrated according to the Bregman's formula. The included teeth were extracted. Theroot canal endodontic file was inserted into the root canal and visibility of tip of the file was checked at the apical foramen and actualworking length was determined.
RESULTS: Among total of fifty patients, the mean difference between the calibrated working length and actual length was measuredfor each tooth. The mean difference was .030 mm with the standard deviation of ±1.29524. There was an insignificant differencebetween the two groups (p=.871) with the confidence level of 95%.
CONCLUSION: There is an insignificant difference between digital radiographic working length by Bregman's method and actualworking length of root canal of teeth.
KEY WORDS: Root canal treatment, digital radiographic working length, actual working length, Digora system, parallelism technique
