  • Rieger syndrome is a rare, autosomal dominant genetic disorder characterized by malformation of the anterior chamber of the eye(goniodysgenesis) coincident with hypodontia. It may also be accompanied by a spectrum of dental, craniofacial and somatic anomalies. Mutations in paired-like homeodomain transcription factor2(PITX2) are associated with the syndrome, and its frequency in the general population has been estimated to be 1 : 200,000. In the present case, the patient, 4 year 7 month-old female, had posterior embryotoxon and polycoria. The maxilla was retrusive in cephalometric radiography. She had congenital missing on #52, #62 and some tooth germs of permanent tooth were not detected in panoramic radiography. The purpose of this paper is to report the dental and craniofacial findings and review the pertinent literature through this case.

  • Axenfeld-Rieger syndrome (ARS) is a rare disorder with variable morphology characterized by malformations of the anterior segment of the eye such as iris hypoplasia, iridocorneal adhesions, corectopia and polycoria. Craniofacial and dental anomalies are also regularly reported in connection with ARS. Dental features include hypodontia in primary and permanent dentition, microdontia, short roots and abnormally shaped teeth. The patient in this case is a 14-year-old girl who has visited Seoul National Dental Hospital in 2002 for the first time. A panorama was taken on the day of her first visit, and total absence of maxillary anterior dentition and mandibular premolars were observed. The patient was on a treatment schedule by the department of ophthalmology at Seoul National Hospital for a morphological dyplasia of the pupil and she was diagnosed with ARS. Periodic panoramic observations were performed followingly, and she was finally diagnosed of congenital missing of maxillary anteriors and mandibular second premolars. In 2009, composite resin build-ups of maxillary primary central incisors were performed, and she has been on her regular follow-ups until now.
