Economic analysis of the different endodontic instrumentation techniques used in the Unified Health System.

Background: To assess the financial impact of incorporating a new (reciprocal) technology into endodontic treatments in the public health system (SUS).

Methods: This was a economic evaluation study (comparing the 3 different endodontic instrumentation techniques-manual, rotary and reciprocating), allocative efficiency analysis to optimize existing resources in the SUS, and financial contribution impact analysis of incorporation of a new technology. Thirty-one (31) 12 years-old volunteers were evaluated.
