Abstract
The purpose of this study was to evaluate the effect of anatomical predisposing factors on the development of furcation involvement. Root trunk length, root divergency angle, buccal root trunk concavity and cervical enamel projection of the mandibular 1st and 2nd molars with(l03 teeth) and without(42 teeth) furcation involvement and enamel projection were classified by Lindhe's degree and Masters's classification, respectively, and buccal root trunk concavity was examined by probing. Statistical analysis was performed by means of ANOVA and CHI-SQUARE test in Microstat. The obtained results were as follows : 1. Root trunk length was longer in teeth without furcation involvement(
