Abstract
Objective To evaluate the clinical effect of cone beam computed tomography (CBCT)as an adjunctive therapy of endodontic treatment for calcified canals,and discuss the clinical significance.Methods Three hundred and seventy-four teeth were selected,which needed to get the root canal therapy,and all of them were blocked with calcification completely in x-ray.The 185 calcified canals that could not be negotiated during the conventional root canal therapy were treated under the endodontic microscope combined with ultrasonic instruments.The negotiation rates were calculated.After that,the 46 canals which could not be negotiated continued to be treated with the help of CBCT,and the negotiation rates were calculated.Results During the conventional root canal therapy,374 teeth were treated;185 root canals were not negotiated.After that,these blocked canals were treated under the endodontic microscope combined with ultrasonic instruments.Totally 139 canals were negotiated and the negotiation rate was 75.14％;27 root canals were seen in the CBCT images,and 19 root canals were not.The former included 11 thin root canals,9 canals whose orifices were blocked and 7 canals whose negotiating direction was deviated.With the help of microscope and ultrasonic instruments,all of the 27 blocked canals were treated successfully.The success rate was improved to 89.72％.Conclusion CBCT images can assist to locate the root canal orifice,and show the direction of calcified canal and canal morphology.To some extent,it can improve the negotiation rate of the calcified root canals.关键词
