Apparatus and methods for treating tooth root canals
First Claim
1. A tooth root canal treatment system comprising:
- a manifold having a base member sized and configured to rest on a crown of a tooth and a top member sized and configured to couple with the base member to define an inlet chamber and an outlet chamber,means for preventing fluid communication between the inlet chamber and the outlet chamber,an opening between the inlet and outlet chambers,a needle having a proximal end and a distal end, the distal end of the needle sized and configured for passage through the opening between the inlet and outlet chambers and extending distally beyond the base member and in fluid communication with the outlet chamber, the proximal end of the needle including an opening in fluid communication with the inlet chamber,a fluid supply source coupled to the inlet chamber, andmeans for increasing the efficacy of the system.

Abstract
Systems and methods provide for automated, cyclic delivery and evacuation of a treatment or irrigation solution from a tooth root pulp chamber and pulp canals. A manifold has a base member sized and configured to rest on a crown of an instrumented tooth and a top member sized and configured to couple with the base member to define an inlet chamber and an outlet chamber. The distal end of a needle is passed through an opening between the inlet and outlet chambers and extended distally beyond the base member into a pulp canal. The proximal end of the needle includes an opening in fluid communication with the inlet chamber. A solution is transferred from a fluid supply source to the inlet chamber and through the needle into the pulp chamber and pulp canals. The spent solution is evacuated from the pulp chamber and pulp canals through the outlet chamber. The system further includes additional devices, such as a light source, an electrical source, a heat source, for increasing the efficacy of the system.
