[Endodontic anatomy of lower premolars--apropos of 669 cases]
Abstract
Six hundred sixty nine human mandibular first and second premolars were collected (extracted) and studied. We made roentgenographic studies, sections of extracted teeth. Comparisons with the findings of other investigators were made in regard to the number of roots and number of root canals (in different tables).
