Purpose: Regional odontodysplasia (RO) is a rare dental anomaly affecting primary and/or permanent dentition, and leads to comprehensive treatment need. The purpose of this study was to present a larger consecutive sample with RO, discuss treatment strategies for patients with RO, and review the literature.
Materials and Methods: A consecutive, retrospective sample of seven children with RO (6 males, 1 female) including all patients diagnosed with RO in the eastern part of Denmark was conducted over a period of 15 years. The evaluation included gender, localisation and treatment outcome. A review of the literature and cases published within the last 15 years was conducted.
Result: Referral age was 2-12 years (mean: 7.3 years). The gender ratio was 1:6 (female:male), and the right:left ratio was 3:4. 71% of the patients had RO in the mandible and 29% in the maxilla. 43% had RO in the permanent dentition, while both primary and permanent dentition were affected in 57%. Typically, RO affected incisors and canines. In some patients, RO also affected more distal tooth types. Treatment included early multiple extractions and subsequent combined orthodontics, surgery and prosthetics. A search on RO cases published within the last 15 years was conducted and included 44 cases. The review showed a male and maxillary preponderance. The most common treatment of RO is extraction.
Conclusion: Treatment of RO should take place in interdisciplinary, specialised teams, and individual treatment plans should be designed. Fewer but more extensive treatment sessions under general anesthaesia may minimise the burden of care for the patients.
