OBJECTIVE: To study the therapeutic effect of Bispacx paste on refractory apical periodontitis. Methods: Eighty patients with refractory periapical periodontitis who received treatment in our hospital from December 2012 to December 2013 were randomly divided into treatment group and control group. Forty patients in the treatment group were treated with Tapacox paste in the root canal, while in the control group, 40 cases were treated with iodoform in the root canal. Results: The total effective rate of the 40 patients in the treatment group was 97.5% much better than that of the control group (82.5%), the difference was statistically significant (P <0.05). CONCLUSION: The treatment of refractory periapical periodontitis by Bispacz paste can inhibit the growth of residual germs in root tip and sinus tract, and effectively avoid recurrence of clinical symptoms and re-infection. The curative effect is particularly satisfactory.
