Abstract

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

Claims (20)

1. A kit comprising:

a syringe comprising:

a barrel comprising a proximal end, a distal end, and a sidewall therebetween defining an interior configured to receive an ampule;

a plunger received at least partially within the interior; and

a metal needle tip attached to the distal end of the syringe barrel, and

an ampule, the ampule holding therein a composition consisting essentially of 90% aqueous TCA.

2. The kit of claim 1 , wherein the composition further includes one or more buffers or excipients.

3. The kit of claim 1 , wherein the barrel is configured such that no rubber material and/or no corrosion-susceptible plastic material contacts the composition.

4. The kit of claim 1 , wherein the composition consists of 90% TCA.

5. The kit of claim 1 , wherein the needle is a 30-gauge needle.

6. The kit of claim 1 , wherein the syringe barrel and the plunger are configured to deliver aliquots of the composition when the plunger is depressed.

7. The kit of claim 6 , wherein the volume of the aliquot is approximately 0.5 ml.

8. The kit of claim 1 , wherein the syringe barrel or ampule is formed of glass or a corrosion-resistant plastic.

9. The kit of claim 1 , wherein the syringe sidewall is angled.

10. The kit of claim 1 , wherein the needle is angled relative to the syringe sidewall.

11. The kit of claim 1 , wherein the needle is about 10 mm to about 15 mm in length.

12. The kit of claim 1 , wherein the kit further comprises sodium hypochlorite.

13. The kit of claim 12 , wherein the sodium hypochlorite is provided in an additional ampule.

14. The kit of claim 1 , wherein the kit further comprises EDTA and an alcohol in one or more additional ampules.

15. The kit of claim 14 , wherein the alcohol is isopropanol, ethyl alcohol, and/or absolute alcohol.
