Abstract

Regional odontodysplasia is a relatively rare developmental anomaly of dental hard tissue with characteristic clinical, radiographic and histologic features. It requires a continuous and multidisciplinary approaches, and the aim of treatment for these patients should include aiding mastication, improving aesthetics, maintaining normal vertical dimension and space, allowing normal jaw growth and eruptional management of affected teeth. This report describes three cases of regional odontodysplasia with 2-5 years of follow-up. Conservative treatment is chosen to preserve the affected teeth as long as possible, and periodic radiographic and clinical examination was done. During this time, all teeth except one showed progressive development. An interesting finding observed in our cases was that each tooth even in the same person showed different degree of tooth development and eruption rate. Thus, we colcluded that the treatment plan for regional odontodysplasia should be conservative and individualized and based on the assessment of each tooth.
