Abstract

Provided herein are compositions and kits including trichloroacetic acid, and methods of using the same for debridement during endodontic treatment.

Claims (29)

1. A method of removing a medicament, a sealing material, and/or a filling material from a root canal, comprising applying to the medicament, sealing material, and/or filling material a composition comprising trichloroacetic acid (TCA).

2. The method of claim 1 , wherein the composition consists essentially of TCA.

3. The method of claim 1 , wherein the composition consists of 90% TCA.

4. The method of claim 1 , wherein the composition is applied to the filling material for no longer than five minutes.

5. The method of claim 1 , wherein the medicament, sealing material, and/or filling material comprises calcium hydroxide.

6. The method of claim 1 , wherein the medicament, sealing material, and/or filling material is one or more selected from the group consisting of rubber, gutta percha, plastic, hydroxyl apatite, resin, tricalcium silicate, and a bioceramic.

7. A method of performing endodontic treatment, comprising:

a. performing endodontic access;

b. performing coronal flaring, thereby opening one or more root canals and exposing dental pulp within the one or more canals;

c. applying a composition comprising trichloroacetic acid (TCA) to the exposed dental pulp;

d. applying a composition comprising sodium hypochlorite to the exposed dental pulp;

e. applying a medicament, sealing material, and/or filling material to the one or more root canals;

f. applying a composition comprising TCA to the medicament, sealing material, and/or filling material;

g. cleaning and shaping the one or more root canals;

h. flushing the one or more root canals with a first flushing solution; and

i. drying the one or more root canals.

8. The method of claim 7 , further comprising, after applying the composition comprising TCA to the exposed dental pulp, a step of dispersing the composition comprising TCA toward an apex of the one or more root canals.

9. The method of claim 8 , further comprising repeating the steps of applying the composition comprising TCA to the exposed dental pulp, dispersing the composition comprising TCA, and applying the composition comprising sodium hypochlorite to the exposed dental pulp one or more times, until apical patency is established.

10. The method of claim 7 , further comprising, after flushing the one or more root canals with the first flushing solution, flushing the one or more root canals with a second flushing solution comprising an alcohol.

11. The method of claim 10 , further comprising, after flushing the one or more root canals with the second flushing solution, flushing the one or more root canals with a third flushing solution comprising EDTA.

12. The method of claim 11 , further comprising, after flushing the one or more root canals with the third flushing solution, flushing the one or more root canals with a fourth flushing solution comprising an alcohol.

13. The method of claim 7 , wherein step h. comprises flushing the one or more root canals with EDTA and then flushing the one or more root canals with an alcohol.

14. The method of claim 7 , wherein the composition comprising TCA consists essentially of TCA.

15. The method of claim 7 , wherein the composition comprising TCA consists of 90% aqueous TCA.

16. The method of claim 7 , wherein step c. is performed for not more than five minutes.

17. The method of claim 7 , wherein step f. is performed for not more than five minutes.

18. The method of claim 7 , wherein the medicament, sealing material, and/or filling material comprises calcium hydroxide.

19. A method of removing dentin debris from a root canal, comprising applying a composition comprising trichloroacetic acid (TCA) to the dentin debris.

20. The method of claim 19 , wherein the composition comprising TCA consists of 90% aqueous TCA.
