Abstract
Objective: To investigate the effects of TF and Protaper nickel-titanium instruments on root canal treatment. Method: 90 teeth with pulpitis or periapical that need rootcanal treatment were divided into 3 groups: Group T were prepared by TF nickel-titanium instrument with crown-down technique. Group P were prepared by Protaper nickel-titanium instrument with crown-down technique,and the above two groups were filled with warm qutta-percha vertical condensation technique.Group k wre prepared by manual stainless steel K file with step-back technique (control group),and filled with cold lateral condensation technique. Record 3 groups of root canal preparation time and the number of broken equipment. Evaluation based on the effect of preparation and root canal treatment according before,during and after the x-ray. Result: With TF and Protaper nickel-titanium instrument were able of root canal,and the operating time was shorter than Group K. There were 3 cases of broken equipment with Protaper nickel-titanium files,but in the Group T,there wasnit. Conclusion: The shoping abilty of TF and Protaper nickel-titanium files are better than stainless steel K-files,and the time of preparation of root canal is shortened,the TF nickel-titanium files have the higher fracture resistance ,and the TF nickel-titanium files are especially suitable for the treatment of curved root canals.关键词
