Practitioners can uncover hidden canals and expose separated instruments with Munce Discovery Burs 31 mm Shallow Troughers and original 34 mm deep troughers in six round durable carbide head sizes — #¼, #½, #1, #2, #3 and #4. Also available is the #6 Endodontic Cariesectomy Bur.
The elongated 1 mm diameter shaft design opens a view corridor between the handpiece and the crown, preventing impingement on deep access cavity walls while preserving shaft stiffness for troughing and excavation control.
These burs are heatless and create a more readable surface than ultrasonic tips while providing familiar tactile feedback of slow-speed round burs without the expense of spontaneous breakage.
