Abstract
Objective To evaluate the clinical effect of the ProTaper rotary Nickel-Titanium file on preparation of morlar root canals. Methods 80 patients were randomly divided into two groups.78 curved root canals in experiment group (group PT) were managed by ProTaper nickel-titanium rotary instruments using crown-down technique;while 76 curved root canals in control group (group SS) were prepared by stainless steel K files.AII teeth were obturated with lateral condensation method.The curve level of root canals was measured by X-ray taken before the preparation;the operating time cost for each root canal was recorded during the preparation;the postoperative pain measure was performed after a week.At last,X-ray was taken to evaluate the preparation and obturation of root canal. Results The mean operation time was significantly shorter in group PT than that in group SS (P<0.05).The incidence rate of postoperative pain was significantly lower in group PT than that in group SS (P<0.05).And the right filling of root canals was higher in group PT than that in group SS (P<0.05). Conclusion The ProTaper nickel-titanium rotary instruments can prepare curved root canals effectively and quickly.lt is recommended to be applied in clinical practice.关键词
