An experimental study of reality enhancement technology in root canal treatment with open pulp access
AIM:To evaluate the accuracy of reality-enhanced technology-assisted pulp opening.METHODS:Sixty premolar teeth were randomly divided into two groups and fixed in plaster models.The experimental group underwent the creation of pulp opening access with the assistance of the AR program,while the control group underwent pulp opening using the conventional pulp opening method.The pulp-opened teeth were again subjected to cone-beam computed tomography(CBCT)scanning to assess the success of the pulp-opening access creation,the angular deviation of the actual access from the planned access,the deviation of the horizontal distance between the crown and root,and the amount of material loss were calculated.RESULTS:A total of 60 isolated premolar root canals in the experimental and control groups were successfully localized,and the pulpal approach was successfully created as assessed by postoperative CBCT.The mean values of material loss in the experimental and control groups were 6.66 mm3 and 22.74 mm3,respectively;the mean values of the overall angular deviation of the access were 13.96° and 21.69°,respectively;and the deviation of the horizontal distance between the crowns and roots were 1.19 mm/0.91 mm and 2.77 mm/1.75 mm,respectively.The amount of material loss and access angle deviation produced by the experimental group were significantly different from those of the control group,and the deviation of the horizontal distance between the crown and the root was also significantly smaller in the AR-assisted pulp-opening group than in the conventional pulp-opening group.CONCLUSION:The use of AR-assisted pulpotomizing resulted in better access angles and less material loss.
