Help! Do you think that this restoration will extend into the pulp?

[np01]

Hi! I'm a dentistry student I have my class II coming up. This is my exam tooth (1st premolar) - I haven't seen the patient yet myself so unfortunately I haven't done a pulp test but it should be vital, would you say that this will extend to the pulp or not? Any help would be greatly appreciated as I am worried I will end up having to do an endo! Does the periapical area look sound? The tooth is symptomless.

It does look like it is very close to the pulp. But you can maybe get away with a liner and a filling
