Title: Compared study of root canal length measured by Root ZX endometer and Triple-united method on the quality of root canal obturation
Abstract: Objective To investigate the clinical value of electronic method and triple-united method on the of root canal obturation.Methods 320 permanent teeth with single root canal which need root canal therapy were selected randomly,and divided into two groups,their work length were measured with Root ZX and triple-united method,after root canal clotted temporary,the teeth were imaged with X-ray,then their accuracy was compared.Results There was different significantly in results of X-ray photos between the two groups.The rate of best root canal obturation in experiment group was 91.41%,in comparison group was 68.71%.Experiment group was better than comparison group obviously.Conclusion Root ZX is an effective method of measuring the canal length.
