The dentist would enter the occlusal surface of a posterior tooth.
Explanation:
The dentist must mentally convert the two-dimensional X-ray image into a three-dimensional image of the pulp chamber.

The dentist must then project this outline onto the occlusal surface (the surface that contacts the surface of a tooth in the opposing jaw.
Opening this surface enables the dentist to get a clear view of the root canals.

The dentist then carries out the procedure, and a final X-ray confirms its success.
