Abstract
Objective:To compare the accuracy of static navigation technology-guided root canal therapy and tradi-tional microscopic root canal therapy in clearing single-rooted non-curved calcified root canals.Methods:This study selected a total of 56 single-rooted anterior teeth and premolars extracted due to orthodontic or periodontal diseases at the oral outpa-tient clinic as the research subjects.After simulating the morphology of calcified root canals,the teeth were randomly divided into two groups and arranged in resin base models according to the shape of the dental arch.In the experimental group(n=28),utilizing static navigation technology for root canal therapy,while the control group(n=28),utilizing traditional micro-scopic root canal therapy.CBCT scans and digital optical surface scans were performed before and after treatment,and the du-ration of root canal treatments,the amount of hard tissue loss,and the deviation values of the root canals between the two groups were compared.Results:In this experiment,four teeth in the control group experienced lateral perforation or apical de-viation.The average treatment duration for the experimental group and the control group was(6.92±1.65)min and(14.67±3.72)min respectively,the difference was statistically significant(P<0.05).The average amount of hard tissue loss for the experimental group and the control group was(10.58±1.50)mm3 and(12.95±2.88)mm3,respectively,the difference was statistically significant(P<0.05).The differences in apical deviation(0.40±0.10 mm vs 0.48±0.15 mm)and axial angle(2.04±0.48° vs 4.59±1.89°)between the experimental and control groups were statistically significant(P<0.05),respec-tively,while the difference in coronal deviation(0.29±0.06 mm vs 0.33±0.08 mm)was not statistically significant(P>0.05).Conclusion:The differences in apical deviation and axial angle of root canal therapy guided by static navigation tech-nique are smaller than those of traditional microscopic root canal therapy,the treatment time is shorter,and the loss of tooth hard tissue is less.Root canal therapy guided by static navigation technique is superior to traditional microscopic root canal therapy in the dredging of single non-curved calcified root canals.关键词
