The Munce Discovery Burs (CJM Engineering) look like surgical length contra-angle burs that are readily available in many brands at a much lower cost. I have been using these conventional burs for endo since dental school. Are the Munce Burs any better?
I see that the shafts on the Munce Burs are very slender. Is this any real advantage? I have seen advertisements for ultrasonic tips that do the same thing and are even more expensive. So what is the story here? Are Munce Burs or ultrasonics that much better than the conventional surgical length burs? What is everybody using, especially to trough for the MB2 in maxillary molars?
According to CJM Engineering, the manufacturer of the Munce Discovery Burs: “Every maxillary molar should be explored for the virtually ever-present MB2 canal, and the isthmus between MB and ML canals of mandibular molars should be troughed to remove necrotic debris. These one-of-a-kind 31mm-long narrow stiff-shafted burs are the ideal instruments for “brushing” away structure on the chamber floor – or just beyond – to debride isthmus areas, to reveal and accentuate hidden orifices and to “dress” the chamber floor and walls.”
