“Root canal treatment is the art of treating the invisible.”

EndoMaster makes the invisible part visible, then measures your access against it.

From outlineto orifice.

Design the outline.

Plan the access on the crown first. On an upper incisor you work from the lingual, through the mirror.

Drill like you hold a handpiece.

The bur follows real handpiece orientation. Pick 2.3, 1.8 or 1.0 mm, and check the synced X-ray of the same tooth.

Predict the orifices.

From the exposed pulp, mark where MB, MB2, DB and P open. Then go deeper and see if you were right.

Check it in Help View.

The tooth turns translucent, so you can see the canal against your access before you commit.

Then it’s measured.

Four numbers, each a percentage. No guessing whether the access was good enough.

Orifice estimation

Did you predict where the canals open?

Adequate extension

Is the outline wide enough to reach them?

Over-extension

How much sound dentin went with it?

Depth appropriateness

Did you stop at the right depth?

What the research found, and what it didn’t.

Pre-clinical stress as low as the VR group.

In a randomized controlled trial with 30 fourth-year students, those who trained on EndoMaster reported stress before their first clinical case as low as the VR haptic-simulator group, and significantly lower than control. They also reported more confidence and preparedness.

What it did not show: clinical performance scores for the app group were not significantly different from control.
