Walls that overhang the canal entrances cost you a straight line into the canal. No. 1 is the Start-X tip for finishing them: the sides do the cutting, and the tip itself is deliberately non-active so it will not mark the pulp chamber floor while you work.

› Non-active tip – Dentsply Sirona: avoids accidentally damaging the pulp chamber floor.
› Active lateral part – creates a straight access to the canal.
› Dentsply Sirona's launch material also gives it the removal of restorations, filling materials, caries and dentine interferences from the access cavity.
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.
› EMS thread – M3 x 0.5 mm. Need the other fitting? This tip is also made with an Satelec 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. 1 a range of 8–9 on a EMS miniPiezon, 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.
Why is the end of the tip smooth?
So the walls can be taken back right down to the floor without the tip cutting into it. Dentsply Sirona designed the non-active end for exactly that: to avoid accidentally damaging the pulp chamber floor.
Will it fit my ultrasonic unit?
This is the EMS-thread version (M3 x 0.5 mm), with Dentsply Sirona power settings for the EMS miniPiezon. If your unit takes Satelec-thread tips, choose the Satelec version.
