Regional Odontodysplasia with Actinomycosis Infection: A Rare Case Report

A rare dental developmental anomaly known as regional odontodysplasia (RO) manifests itself in hypoplastic and hypomineralized teeth with discolored yellow to brown enamel. Radiographically, the affected tooth appears as a shell tooth with a large pulp chamber and a thin layer of teeth structure. The treatment plan is not well-established, and a multidisciplinary approach is often needed. However, a literature review revealed that most of the studies regarding RO are case reports, and more research, including epidemiological, genetic, and experimental studies, is needed to understand this condition better. Additionally, the cause of this anomaly is currently unknown. Removing the affected tooth is a controversial matter, and the treatment options should be chosen on an individual basis, considering the patient's goals for treatment. This report describes an uncommon case of an 8-year-old girl who has RO affecting the front teeth in the upper jaw and a long-standing infection caused by actinomycosis.
