ROOT CANAL DEBRIDEMENT EFFECTIVENESS DEVICE AND METHOD

摘要

A method for continuously evaluating the effectiveness of debridement of a root canal (24) of a tooth (18), the tooth (18) having an open access cavity (25) and an apex end (26), includes delivering a fluid to the open access cavity (25) of the tooth (18), evacuating the fluid near the apex end (26) of the tooth (18) such that the fluid flushes most of the root canal (24) before being evacuated, and continuously evaluating the evacuated fluid for at least one of a presence of debris (86), a concentration level of the debris (86), or a type of the debris (86). An apparatus (10) for use in debriding a root canal (24) of a tooth (18) includes a microcannula (38) or a macrocannula configured to evacuate a fluid in the root canal (24), and a sensing mechanism (14) fluidically coupled to the microcannula (38) or the macrocannula.
