After having examined the many theories on the pathogenesis of molar polydontias, the paper describes a very interesting clinical case involving the lower 4th molar. The results suggest that the most reliable theories are those postulating either the hyperactivity of the epithelial tract or the proliferous production of enamel (in the broadest sense).
