    This question is from 1989 released exam. There are two questions ask about the attached picture.
    1. The arrow shows path way of which cusp of which tooth during this movement?
    Clearly, it's the lingual cusp of the first maxillary premolar.
    2. What movement is this?
    Based on question 1, it's clear this is the left lateral, working side
    Based on the guide in the decks: pointing lingually and straight indicates left lateral, working side.

    Now, if the right mandible is shown instead with an arrow also pointing lingually. Two same questions asked. How would you answer the second question? Based on the methods I listed above, it would result either right or left lateral. What do you think?

    You're talking about a mirror image of this picture, right? If there were a mirror image, with the arrow pointing in the same way, the answer would be right lateral, working side.
