Abstract
Objective:The calcified block root canals have greatly influenced the curative effect to the root canals.To observe the EDTA paste in the application of calcified block root canal preparation,evaluate its clinical efficacy.Method:One hundred and twenty-four patients in our department from March 2009 to March 2012 were selected,140 back molar teeth,165 calcified block root canals and then divide them randomly into the group A and the group B,62 cases in each group.There were 62 cases,68 back molar teeth and 83 calcified block root canals in the group A.The group A was treated with the EDTA paste into root canal occlusion for root canal preparation,or temporary seal root canal EDTA root canal preparation a week later.There were 62 cases,72 back molar teeth and 82 calcified block root canals in the group B.The group B was treated with chloramine into the calcified block root canals and then had a root canal preparation.The preparatory effect of the root canals according to the X-ray and clinical examination were evaluated. Result:Eighty-three calcified block root canal in the group A with 72 root canal expansion,prepared well,the success rate was 86.75%.82 calcified block root canal in the group B only 18 root canal in root canal expansion,the success rate was 21.95%,and the breakage rate increased,the difference was statistically significant(P<0.01).Conclusion:The effect that EDTA paste has been used in the calcified block root canals is very good.It can raise remarkably the successful rate of root canal preparation.关键词
