Abstract

Dens invaginatus is one of the developmental abnormities of the tooth which occurs with an invagination of the enamel organ into the dental papilla during tooth development. This abnormity presents a wide spectrum of morphological variations. According to Oehlers classification, in dens invaginatus type II the invagination invades above the cemento-enamel junction, connecting to the pulp; however, there is no connection with the periodontal ligament. This abnormity presents significant challenge when root canal treatment is necessary. The most frequently affected teeth are permanent maxillary lateral incisors, followed by permanent maxillary central incisors. There are limited case reports of mandibulary central incisors; however, there is no publication of mandibular lateral incisors with dens invaginatus type II. This case report aimed to present cone-beam computed tomography aided diagnosis and treatment for type II dens invaginatus in a mandibular lateral incisor with a talon cusp and a large periapical lesion.

Tip II Dens Invajinatus Bulunan Mandibular Lateral Keser Dişin Tedavisi: Nadir Görülen Bir Vaka Raporu

Abstract

Dens invaginatus, diş gelişimi sırasında mine organının dental papillaya doğru invajine olması ile ortaya çıkan dişin gelişimsel anomalilerinden biridir. Bu anomaliye sahip dişler çeşitli morfolojik varyasyonlara sahip olabilmektedirler. Oehler'in sınıflamasına göre, dens invaginatus tip II'de invajinasyon mine-sement birleşimini geçer, pulpaya bağlanır; ancak periodontal ligaman ile herhangi bir bağlantı bulundurmaz. Bu anomali, kök kanal tedavisinin gerekli olduğu durumlarda sıklıkla önemli bir zorluk teşkil eder. En sık etkilenen dişler daimî üst lateral kesici dişlerdir ve bunu daimî üst santral kesici dişler takip etmektedir. Mandibular santral kesici dişlerle ilgili sınırlı sayıda vaka raporu bulunmaktadır; ancak dens invaginatus tip II'ye sahip mandibular lateral kesici dişlere ilişkin yayın bulunmamaktadır. Bu vaka raporunda, talon tüberkül bulunan ve büyük periapikal lezyonu olan dens invaginatus tip II’ye sahip mandibular lateral kesici dişin konik ışınlı bilgisayarlı tomografi desteği ile tanı ve tedavisinin sunulması amaçlandı.
