X2 Endo™ #03 Molar (UR6)

X2 Endo™ · #03 upper right first molar · dual hardness

The MB2 that merges, then leaves again – the flagship teaching molar

Which single tooth teaches an upper first molar properly? Acadental call this one their flagship, and the reason is what the mesiobuccal root does: the MB2 merges mid-root with MB1, and the two then diverge apically. That is the configuration that catches experienced operators, not just students. Around it sits a fairly benign distobuccal canal with an apical diameter of approximately .20 mm and a palatal root with about a 30 degree radius through its mid-section – enough curvature, Acadental note, for even a novice to learn negotiation.

› Radiographs like an extracted tooth – Acadental claim radiopacity of natural teeth with no adjustments, with the enamel-to-dentin contrast visibly highlighting the crown and root.
› Use a diamond bur – Acadental's own instruction, because the replicated enamel is comparable in hardness to a natural tooth.
› The undergraduate alternative – Real-T Endo #03 also has an MB2 system and radiographs fully, at a lower price per tooth.

Is dual hardness worth paying for?
If access is being taught or assessed, yes. A single-hardness tooth lets a bur sink through the roof at a rate that teaches nothing about depth control. If the exercise starts after access, the saving on Real-T is better spent on more teeth.

Can students find the MB2 without a microscope?
Some will and some won't – which is the lesson. Because the tooth radiographs properly, the ones who missed it can be shown on film rather than told.

What about seeing inside the canal?
That is the see-through Endo 3DP #03, which comes pre-accessed with an isthmus, lateral canal and fin – but is radiolucent, so no films.
