Abstract

The authors investigated on 1216 extracted upper and lower premolars the morphology of the root canals. In the upper first premolar one root canal was found in 42,53%, two root canals in 54,02% and the presence of three root canals was in 3,45%. The second upper premolars had one root canal in 86,32% and two root canals in 13,62%. Among lower premolars one root canal existed in 98,20%, two canals in 1,80% in the firs t and in the second lower premolars one root canal in 97,16%, two root canals in 2,84%. Besides the findings of root canals the appearence of longitudinal furrows has been investigated. In the paper own records are being compared with the findings in the available literature.
