Abstract
The incidence of the fusion of the roots of molar teeth was studied by
analyzing the orthopantomograms of 119 patients of both sexes. A total of 889 molars, i.e. 448 in the upper and 441 in the lower jaw, were examined. As many as 30.8% of the molars were found to have fused radices. The incidence was slightly higher in the upper (40.5%) than in the lower jaw (40.1%). X-ray of the teeth moist often revealed root fusion in the third upper molars (70.5%), then in the second upper molars (47.8%) and the least frequently in the first lower molar teeth. The results also point to a marked similarity in the appearance of fusion in both jaws in all examines.
