新型生物陶瓷材料iRoot FM作为乳牙根管充填材料的动物实验研究
An animal study of a novel bioceramic cement iRoot FM used as root canal fillings in primary teeth
摘要
Abstract
Objective To study the therapeutic effect of a novel bioceramic cement iRoot FM as a root canal filling material in the primary teeth of Beagle dog,and to assess the consistency of the resorption rate of root canal filling material and primary teeth root.Methods Totally 22 primary teeth (32 root canals)of beagle dogs were divided into two experiment groups (iRoot FM group,Vitapex group)and a normal control group.The teeth in the experiment groups were conducted by root canal therapy.The oral and radiographic examination was assessed by three senior dentists and radiographic experts blindly every two weeks postoperatively.Statistical analysis was performed by SPSS 18.0 software.Data were analyzed using Fisher's exact test to compare the success rates.Results The oral and radiographic examination assessment indicated that the success rates of iRoot FM was 100％ (10/10).The success rate of Vitapex group was 100％ (10/10) at the end of 8 weeks,and then declined to 80％ (8/10).There was no statistically significant difference between these two groups (P ＞ 0.05).There was no statistical difference between the iRoot FM group and the Vitapex group on the consistency of resorption rates of the root canal filling material and primary teeth root 2-14w after operation (P ＞ 0.05).Conclusion iRoot FM can be resorpted with the physiological resorption of primary teeth after root canal therapy.It can be a new option for root canal filling material in primary teeth.关键词
