Abstract

Regional odontodysplasia is a rare anomaly of enamel, dentine and pulp tissue without any hereditary patern. The etiology of regional odontodysplasia is unknown. This anomaly generally involves only one quadrant of the mouth, and anterior maxillary teeth are mostly affected region. Hypoplastic and brown colored teeth are characteristic for regional odontodysplasia. Absent teeth or impacted teeth are also common with this pathology. Wide pulp chambers and less radiopaque teeth appearance is typical ghost teeth in radiographic examination. The clinical differentiation of regional odontodysplasia and amelogenesis imperfecta is really difficult because of their similar clinical features. Clinical, hystopathological and radiographic evaluation should be considered together for differential diagnosis. Because of the damaged tooth structure, ideal and long lasting treatment in patients with regional odontodysplasia is a distressing issue

Dört Yarım Çeneyi İçeren Atipik Rejyonel Odontodisplazi

Abstract

Rejyonel odontodisplazi nadir görülen, mine, dentin ve pulpanın herediter olmayan bir anomalisidir. Rejyonel odontodisplazinin etiyolojisi bilinmemektedir. Bu anomali genellikle ağzın sadece bir kuadranını içerir ve maksiller keser dişler sıklıkla etkilenen dişlerdir. Hipoplastik ve kahverenkli dişler rejyonel odontodisplazi için karakteristiktir. Eksik veya gömülü dişler bu patolojide sıklıkla görülmektedir. Radyolojik incelemede, geniş pulpa odalı, azalmış radyoopasiteye sahip ‘’hayalet diş‘’görüntüsü mevcuttur. Rejyonel odontodisplazi ve amelogenezis imperfektanın benzer özellikleri nedeniyle klinik olarak ayrımlarını yapmak oldukça zordur. Ayırıcı tanı için klinik, histopatolojik ve radyografik değerlendirme birlikte yapılmalıdır. Diş yapısındaki hasar yüzünden ideal ve uzun ömürlü restoratif tedavi rejyonal odontodisplazi hastalarında sıkıntılı bir konudur
