Provides precise, efficient canal access and exploration. Patented, conical shaped micro-diameter tip acts as a self-centering guide, permitting straight-line access to canals while conserving vital peri-cervical dentin. Blade design efficiently cuts in vertical and lateral directions, leaving a polished dentin surface as it cuts. Diminutive bur size and shape is ideally suited for microscope-enhanced endodontics, allowing for a less obstructed view of the pulp chamber and canal orifice.
