Title: Clinical Evaluation on the Preparation of Molar Root Canals with ProTaper Rotary Instruments
Abstract: Objective: To evaluate the quality of molar root canal preparation using ProTaper rotary instruments.Methods: From July 2007 to December 2010,109 adult patients with 128 affected molars who were diagnosed to receive root canal treatment were divid-ed into two groups based on the randomly-paired principle.There were 64 teeth in each group.In group A,root canals were prepared with rotary ProTaper files in crown-down mode,and in group B root canals were prepared with traditiona1 stainless stee1 K files by hand.All root canals were obturated with lateral condensation method.The time consumed in preparation of each canal was recorded.The outcome of root filling and side effects occurred after the operation were also noted.1 year later all the cases were revisited and the therapeutic results were verified.Results: Time consumed in the preparation of group A was significantly less than group B.Exact filling rate of canals prepared with rotary ProTaper files was higher than with k files and side effects after the operation such as tooth ache and swelling less occurred.One year post operational follow-up survey showed better therapeutic effects of root canal treatment in the group using rotary ProTaper files.Conclusion: Compared with instrumentation with traditional stainless steel K files by hand,molar root canal preparation with rotary ProTaper files is 1ess time consuming and more convenient.The occurrence of side effects was less and the out-come of root filling was more satisfactory.
