Talon Tüberkülü: İki Olgu Sunumu

Abstract

Talon tüberkülü kesici ve kanin dişlerde görülen, mine ve dentin dokusundan oluşan, bazen pulpa uzantılarının da içerisinde bulunduğu aksesuar bir tüberkül olarak tanımlanır. Bu durum Mohr Sendromu, Incontinenta pigmenti Achromians, Ellis-van Creveld Sendromu, Struge Weber Sendromu, Rubinstein Taybi Sendromu ve Alagille Sendromu gibi sendromlarla birlikte de bildirilmiştir. Bu makalenin amacı iki ayrı vakada görülen talon tüberkülünü tanımlamaktadır. Birinci vakada talon tüberkülü, maksiller sol santral dişin lingual yüzeyinde görülmektedir ve servikal kenardan insizal kenara uzanan, dişin mesiodistal yüzeyine dik olarak konumlanan spesifik bir talon tüberkülü bulunmaktadır. İkinci vakada da maksiller santral ve lateral dişin lingual yüzeyinde, dişin servikal kenarından insizal kenarının yarısına kadar uzanan bilateral talon tüberkülü saptanmıştır. Bu iki vaka raporunda, radyografinin de V-şeklinde radyopak bir görüntü verdiğini saptanmıştır. Sonuç olarak talon tüberkülü nadiren karşılaştığımız bir dental anomalidir. Bu anomali sistemik sendromlar ile birlikte görülebilmektedir; Bu nedenle, klinisyenler bu anomaliye ilişkin yeterli bilgiye sahip olmalıdır.

Talon Cusp: Two Case Reports

Abstract

The talon is an accessory, irregular cusp on incisors and canines, involving in enamel and dentine with or without pulp tissue.It was also reported in association with syndromes, for example, Mohr Syndrome, Incontinenta pigmentii Achromians, Ellis-van Creveld Syndrome, Struge Weber Syndrome, Rubinstein Taybi Syndrome, and Alagille’s Syndrome. The aim of this paperwas to describe talon tubercules in two cases. In first case the talon cusp is seen on lingual surface of the maxillary left central tooth and there is a specific talon tubercle which extending from the incisal edge to the cervical edge, perpendicular to the mesiodistal surface of the tooth. In second case bilateral talon tubercles were detected extending from the cervical region less than half of the incisal margin on the lingual surface of the maxillary central and lateral teeth. This present two case reports  radiograph gives a v-shaped radiopaque image.Talon tubercle is a dental anomaly we rarely encounter. Consequently this anomaly may occur with a systemic syndrome Therefore, clinicians should have adequate knowledge of this anomaly.
