Regional odontodysplasia (ROD) is a rare developmental anomaly with distinctive clinical, radiographical and histological findings, affecting both primary and permanent dentitions. The teeth with ROD have an atypical morphology and are usually discolored, with either delayed eruption or complete failure to erupt. Radiographically, the affected teeth have a "ghostly" appearance, with marked radiolucency and decreased radiodensity, showing a thin outline of enamel and dentin, which appear hypomineralized histologically, with poorly structured dentinal tubules and enamel prisms. Calcifications are frequently found in the pulp chambers of the affected teeth. This case report discusses a three-year-old girl who presented with ROD in her mandible as well as the clinical and radiographical features, and treatment of the condition.
期刊介绍：
Acquired after the merger between the American Society of Dentistry for Children and the American Academy of Pediatric Dentistry in 2002, the Journal of Dentistry for Children (JDC) is an internationally renowned journal whose publishing dates back to 1934. Published three times a year, JDC promotes the practice, education and research specifically related to the specialty of pediatric dentistry. It covers a wide range of topics related to the clinical care of children, from clinical techniques of daily importance to the practitioner, to studies on child behavior and growth and development. JDC also provides information on the physical, psychological and emotional conditions of children as they relate to and affect their dental health.
