Clinical Study of Cone Beam CT and Root Canal Microscopy in Patients with Complex Root Canals
To explore the clinical value of cone beam CT and root canal microscopy in complex root canal patients. Ninety
patients with complicated root canals admitted to our hospital from January 2018 to November 2019 were
randomly divided into observation group (cone beam CT examination) and control group (root canal
microscopy) with 45 patients each. The number of root canals detected, root canal dredging and the effect of
root canal treatment were compared between the two groups. Compared with the control group (84.17%), the
root canal detection rate in the observation group (93.33%) was higher with statistical significance (P<0.05); the
root canal dredging rate in the observation group (93.75%) was higher than that in the control group (81.46%)
(P<0.05).At the same time, the treatment success rate in the observation group (95.56%) was higher than that in
the control group (77.78%) (P < 0.05), with statistical significance. None of the patients had root canal deviation,
root canal steps, or separation of instruments during the treatment. In complex root canal therapy, cone beam CT
and root canal microscopy can play an assistant role in detecting and locating the root canal accurately. At the
same time, it plays a guiding role in the process of root canal dredging to ensure smooth root canal treatment.
Compared with root canal microscopy, cone beam CT can improve the detection rate and root canal dredging
rate, and its treatment success rate is also high.
