Abstract

<p>Teeth with a supernumerary root, such as a double, additional, extra, or accessory root, or multiple roots, are a deviation from the general form. A supernumerary root can occur in nearly all types of permanent teeth, while it is extremely rare in deciduous teeth. In Japan, there are only a few clinical reports of such an occurrence in maxillary and mandible primary canines, or maxillary second and mandibular primary molars, while clinical reports of a maxillary primary central incisor with a supernumerary root are available. Here, we report a case of a maxillary primary central incisor with an additional root that caused disturbance of permanent tooth eruption.</p><p></p>
