Dentists are often tempted to prepare simple cavities inthe mesial surfaces of first and second bicuspids and occa-sionally in the molars. If this is ever done, it must be withthe full knowledge both of the liability of recurrence of cariesand the structure of the enamel, for experience shows that Fig. 105
