Abstract:
Objective To investigate the clinical effects of single-file root canal preparation combined with iRoot sp single-tip root canal filling in the treatment of chronic periapical inflammation.
Methods A total of 100 patients with chronic periapical periodontitis scheduled by one-time root canal treatment were randomly divided into the study group (group W) and control group (group P), with 50 patients (teeth) in each group. The group W was treated with root canal preparation of single-file system Wave one Gold combined with iRoot sp single-tip method. The group P was treated with Protaper Gold root canal preparation combined with AH Plus hot glue vertical compression method. The success rate of one-time root canal preparation, single canal preparation time, single canal filling time, root canal filling quality and postoperative pain between two groups were compared. Two groups were re-examined after 6 months of surgery, and the effectiveness of root canal treatment was compared between two groups.
Results The success rate of root canal preparation in the group W was significantly higher than that in group P (P < 0.05). The root canal preparation time in the group W was significantly less than that in group P (P < 0.01). The filling rate in the group W was higher than that in group P (P < 0.01). The required time of single canal filling in the group W was significantly less than that in group P (P < 0.01). There was no statistical significance in the VAS scores after 24 h of operation between two groups (P > 0.05). The VAS scores in the group W were lower than those in group P at 48 h and 72 h after operation (P < 0.01). Six months later, the effective rate in the group W was higher than that in group P (P < 0.05).
Conclusions Compared with Protaper Gold root preparation and AH Plus hot glue filling, the single-file system Wave one Gold root preparation combined with iRoot sp single-tip method for one-time root canal treatment for teeth with chronic periapical inflammation takes less time in the root canal preparation and filling, has good filling rate and low and mild postoperative pain incidence, and the treatment results are better at 6 months after surgery.
