Abstract

Background:  The aim of present in-vivo study was to evaluate and compare the working length obtained by conventional radiography and electronic apex locator in primary molars.  Material and Method: 120 canals from 40 mandibular primary molars were selected and working length was estimated using radiographic and electronic apex locator (iPex) and compared for clinical accuracy between both the methods. The mean of working length of individual canal (mesiobuccal, mesiolingual and distal canal) of each mandibular primary molar was also compared. Data were statistically analyzed by using paired t test.  Result: The overall mean working length (13.02±1.25mm) determined by electronic apex locator method was slightly greater and accurate than determined by using conventional radiographic method (12.95±1.27mm). When the mean of working length of individual (mesiobuccal, mesiolingual and distal) canals was compared, working length of the overlapped canals (mesiobuccal and mesiolingual) were found to be more accurate by electronic apex locator (iPex) than that of by radiographic method. Conclusion: Though no statistical significant difference (p=0.28) was obtained between working length determined by electronic apex locator and radiographic method; working length determined by electronic apex locator was found to be more accurate.
