Thirty-six maxillary impacted canines which showed coronary resorption were selected out of 252 impacted canines. Clinical, radiographic and histologic observations were performed. In the majority of the cases (31) a local inflammatory factor was present and only in five cases was the resorption idiopathic. The incidence of resorption was highest in the later decades of life. In all cases bone replacement was found.
