The Clinical Effect Comparison of Hot Gutta-Percha Filling and Cold Gutta-Percha Lateral Condensation in the Teeth Root Canal Filling

Objective: To observe the clinical effect of hot gutta-percha filling and cold gutta-percha lateral condensation in the teeth root canal filling.Methods: Collect 62 patients with the acute pulpitis and apical periodontitis,they were divided into the hot gutta-percha group and the cold gutta-percha group,then compare the teeth root canal filling time,the postoperative patients with the periodontal pain,the filling quality and the clinical effect after 3 months.Results: There was no statistical significant(P0.05) in the postoperative patients with the periodontal pain,there was a statistical significant(P0.05) in the remaining aspects,the hot gutta-percha group's clinical effect were better than the cold gutta-percha group's.Conclusion: We should use hot gutta-percha filling in the teeth root canal filling first,it could significantly improve the clinical effect and did not increas the incidence of postoperative periodontal pain.
