In upper molars, the entrance to the second mesiobuccal canal is often hidden under dentine. No. 2 is the Start-X tip Dentsply Sirona designed for locating it: an active tip that removes that dentine, with active sides to open a straight path to the canal.

› Active tip – Dentsply Sirona: removes the dentine that often conceals the MB2 access in upper molars.
› Active lateral part – creates a straight access to the canal.
› Dentsply Sirona's directions give it one indication: locating the MB2 canal, the second canal of the mesiobuccal root.
Dentsply Sirona developed the five Start-X tips with Professor Berutti, Professor Cantatore and Dr Castellucci on a simple principle: one tip, one clinical indication, to facilitate and optimise the preparation of the access cavity.
In Dentsply Sirona's words: “higher control and precision with ultrasonic inserts specifically designed for access cavity refinement and canal orifice location.”
› Micro-milled active part – in Dentsply Sirona's words, minimising the risk of diamond grit loss in the patient's mouth.
› Resistance to fracture – Dentsply Sirona describe it as excellent.
› Satelec thread – M3 x 0.6 mm. Need the other fitting? This tip is also made with an EMS thread.

› Secure the tip to the handpiece with the key before use.
› Start at a lower power setting and only increase it if necessary to safely accomplish the task. Dentsply Sirona give No. 2 a range of 16–18 on a Satelec P5 / Newtron, adjusted to the clinical application; check your unit's own instructions too.
› Irrigation is recommended for procedures that need high power, to avoid overheating.
› A visual aid is recommended, for comfort and safety. Never run the generator with a damaged tip.
› Contraindications: none known when used as recommended, but Dentsply Sirona recommend not using the tips in patients with a pacemaker.
Once the MB2 entrance is found, what next?
That part is your protocol, not ours. For negotiating a fine canal we stock C-PILOT® 08 and C-PILOT® 10 in 21 mm, and the Micro-Opener 10/.04.
Will it fit my ultrasonic unit?
This is the Satelec-thread version (M3 x 0.6 mm). Dentsply Sirona give its power settings for Satelec P5 / Newtron units. If your unit takes EMS-thread tips, choose the EMS version.
