Abstract Introduction: Working length estimation is one of the important factors for biochemical preparation and obturation of root canal system. Some patients were unable to film toleration (in intra oral technique) or were Sensitive in (digital radiographic technique). Objective: The goal of this study was comparison kind of extra oral radiographic technique (that Conventional P.A Film was out of mouth) for patient who were unable in film toleration in intraoral technique with intraoral method in estimation of working length of molar teeth in endodontics. Materials and Methods: In this descriptive cross sectional study, two images with conventional P.A film were provided from 33 volunteer patients that their molars teeth followed by RCT and were in primary file step. First image was taken by intra oral method and parallel technique, (XCP) second image was taken by extra oral method. Then, length of canal was estimated, twice in 0.5 and 1 mm from the radiographic apex, randomize by an endodontist in two weeks period. Data was analyzed with SPSS statistical software and Pearson correlation test was send to compare two variables effect on working length Estimation in molar teeth. Results: As the results, working length estimation of molar teeth in both extra and intra oral radiographic method was correlated (p<0.001, r>0.59). Also agreement percentage of working length estimation were different in both intra and extra oral radiographic method (at least 25% in palatal root from 0.5 mm to apex up to 75% distal root from 1mm to apex). Conclusion: Extra oral radiographic technique with conventional periapical film could be effective in patients who were unable to tolerate or sensitive to film.
