Effects of combining CBCT technology with visual root canal recurrence in treatment of elderly patients with dental pulp disease.

OBJECTIVE The aim of this study is to analyze the effects of combining cone beam computed tomography (CBCT) technology with visual root canal recurrence in the treatment of elderly patients with dental pulp disease. PATIENTS AND METHODS 56 cases of elderly patients with dental pulp disease were contiguously selected, and randomly divided into the control group (70 teeth from 27 patients) and the observation group (77 teeth from the rest 29 patients). We adopted CBCT technology combined with conventional root canal therapy in control group and CBCT technology combined with visual root canal recurrence in observation group to compare the clinical effects. RESULTS It was found that there was no statistical difference in duration of operation between the two groups (p>0.05). The operation times and the VAS during and after operation of the observation group were significantly less than that of the control group (p<0.05). The duration of follow-up of the two groups was both about 18 months. Successful rates of treatment for 6 months and by the end of follow-up visit in the observation group were both significantly higher than those in the control group (p<0.05). The correct filling rate, good filling rate and fair filling rate in the observation group were significantly higher than those of the control group (p<0.05). CONCLUSIONS CBCT technology combined with visual root canal recurrence can significantly improve the near and long-term treatment effects of elderly patients with dental pulp disease.
