Pertinence of the Tactile Controlled Activation(TCA) technique in the management of severely curved root canals - A report of two cases.

Canal curvatures such as dilacerated canals, bayonetshaped canals, and acute curvatures in the apical third pose a therapeutic challenge to the clinician. Pretreatment determination of the degree of curvature, usage of scrupulous instrumentation techniques facilitate successful negotiation of the bends and enhance the quality of the treatment. The following case series chronicles the application of a novel instrumentation technique known as Tactile Controlled Activation(TCA) technique in the management of sharp apical curvatures in a molar and a premolar, thus upholding its accountability in the management of canal curvatures without any iatrogenic mishaps, besides maintaining the original trajectory of the canal.
