[Curative effect of warm gutta-percha filling technique combined with different sealers in root canal filling].

PURPOSE: To evaluate the clinical curative effect of warm gutta-percha filling technique combined with different sealers in root canal filling.

METHODS

Ninety-five patients with pulpitis who underwent root canal filling from June 2015 to June 2017 were selected. They were randomly divided into group A (n=30), group B (n=33) and group C(n=32). Group A was treated with warm gutta-percha filling technique + iRoot SP, group B was treated with warm gutta-percha filling technique + AH plus, and group C was treated with warm gutta-percha filling technique + Vitapex. The quality of root canal filling at 7 days after surgery was compared among the three groups, and the pain degree was assessed. Statistical analysis was performed using SPSS 19.0 software package.

RESULTS

There was no significant difference in the rate of suitable filling among the three groups (P>0.05). The rates of level 1 pain in group A and group B (6.7% and 6.1%) were significantly lower than that in group C (28.1%) (P<0.05).

CONCLUSIONS

The root canal sealing effects of warm gutta-percha filling technique combined with iRoot SP or AH plus or Vitapex are good. However, compared with Vitapex, iRoot SP and AH plus can relieve symptoms of pain after root canal treatment more effectively. They are suggested as the preferred sealers in root canal filling.
