REGIONAL ODONTODYSPLASIA: A CASE REPORT

Abstract

Objective Report a case of regional odontodysplasia in the maxilla of a pediatric patient and the immunohistochemical expression of different types of collagen. Regional odontodysplasia is a rare developmental anomaly, involving the ectoderm and ectomesenchyme of the temporally and permanent teeth. It tends to be locallizated in only one arch of the jaws. Case report A 8-year-old female patient, with no significant hereditary or pathological history. On examination dental agenesis C, D, E is observed. Radiographically revealed 6, 7 and 8 with radiopaque contour and loss of the delimitation between enamel-dentin complex, giving an appearance of ghost teeth. Surgical treatment was performed. Microscopic examination follicular tissue contains scattered collection of enameled congregates and islands of odontogenic epithelium. Immunohistochemical expression of different types of collagens was heterogeneous in the dentin (col. 1,2,3,4,5,6,10 and 11). These results are consistent with an abnormal dentin development. Conclusion Regional odontodysplasia is an alteration that develops at a very early age, so the interdisciplinary management and the choice of treatment are fundamental since the treatment must be specific for each patient.
