I am going to do a DO on 28(1st mandibular premolar) for my WREB exam. I am debating if I should cross the transverse ridge anyways during the exam. I plan on placing a composite in the tooth. What do you think? Should I take a chance and play it safe by just crossing it? If I don't I feel like I will be just doing a slot prep which can get tricky. Do you think I will lose points if I cross it even if the mesial doesnt seem to have any caries? I am trying to play it safe. Thanks for any replies.
