BISECTING VERSUS PARALLELING CONE TECHNIQUE IN THE ACCURACY OF WORKING LENGTH DETERMINATION-INVITRO STUDY
Dr Shalini, Dr Ramaprabha
Abstract :
Introduction: The aim of this clinical study is to compare two radiographic techniques for determining working length of root canals namely bisecting and paralleling cone technique and to analyse whether the method of working length determination (Ingle/Grossman) or the technique of radiographic imaging plays a significant role in accurately determining root canal length. Methods: A total number of 22 extracted teeth with 29 roots was collected and cleaned. Paralleling and bisecting angle techniques were used both preoperatively and postoperatively. Working length was evaluated using both Ingle’s and Grossman’s methods. The values were compared before and after reducing the saftey factor using the Chi–square test. Results: Both the techniques and methods were statistically significant.Ingle’s method overestimated the length less frequently in bisecting angle technique irrespective of safety factor while Grossman’s method overestimated less frequently with paralleling technique when safety factor was not considered. Conclusion: Bisecting angle technique gave more number of accurate values with Grossman’s method when safety factor was considered. Paralleling technique gave more number of accurate values with Ingle’s method when safety factor was considered.
