routine radiographic examination of a 58year-old woman revealed chronic periodontitis and unusually impacted third and fourth molars.

tion, the maxillary right central incisor appeared to be only partially erupted, with a Class II mobility. The tooth was asymptomatic. On radiographic examination, the root was found to be completely resorbed, leaving only the endodontic filling material and a jagged cervical margin. Past history revealed direct trauma to the area when the patient was 10 years of age, resulting in complete evulsion of the tooth. The tooth was treated endodontically and splinted into occlusion for approximately 6 weeks.
