Furcation involvement has been reported to lead poor prognosis because of its complicated morphological bases. Many reports have been made on the anatomical characteristics of molars intending to improve the prognosis. In the present experiment, 54 extracted mandibular first molars were used to find the anatomical characteristics and their mutual relationships, from the periodontal point of viewing, aiding in the diagnosis of furcation involvement. As a result, buccal grove was found in 100%, lingual groove in 96.3%, buccal cervical enemel projection in 68.5%, lingual enamel projection in 33.3% among mandibular first molar teeth examined. Root fluting was seen more frequently and more distinctly on the furcation side of the root than on the other side of the root. Bifurcational ridge was found in 75.9%. There were mutual relationships between some of the less important characteristics, but as far as the coronal and the root structures are concerned, mutual relationships which might be able to regard as a diagnostic criteria in the daily periodontal practice were failed to found.
