cervical line! he loves it when root surface depressions cross the cervical line!!

Perm Max 1st Molar–DISTAL view
Which tooth & surface am I describing? Clinicians MUST BE CARFUL to restore class II preparations on this surface or be mindful of calculus deposits that may engulf the depression, making the calc difficult to remove.
