Management of Double Tooth Affecting Permanent Maxillary Central İncisor: A Case Report

Abstract

It is difficult to clinically make differential diagnosis between fusion and gemination, especially when these anomalies take place together with hypodontia or supernumerary tooth. The term “double tooth” is therefore preferred by many authors. These teeth may occur due to the fusion of adjacent tooth germs, hence the term fusion. Alternatively, this anomaly may be the result of attempted division of a single tooth germ, hence the term gemination. This case report describes the management of double tooth affecting the permanent maxillary left central incisor. As a result of clinical and radiographic examinations, it was determined that this tooth consisted of fusion of central left maxillary incisor and supernumerary tooth. The double tooth was separated for having crown size of adjacent central incisor and supernumerary tooth with related root was extracted. After 1-year follow up, the maxillary left central incisor still remains vital. This case shows that a precise diagnosis is important in sectioning a double tooth, and that cone-beam computed tomography (CBCT)-based data are very useful in planning complex treatment.

Maksiller Daimi Kesici Dişte İzlenen Çift Diş Oluşumunun Tedavisi: Olgu Raporu

Abstract

Füzyon ve geminasyon, özellikle süpernumere diş veya hipodontiyle birlikte görüldüğü durumlarda klinik olarak ayırıcı tanı koymak zor olmaktadır. Bu nedenle çoğu araştırmacı bu dişler için “çift diş” terimini kullanmayı tercih etmektedir. Eğer bu dişler komşu iki diş germinin birleşmesi sonucu oluşuyorsa füzyon; tek diş germinin bölünme girişimi sonucu oluşuyorsa geminasyon olarak tanımlanmaktadır. Bu olgu sunumunda daimi üst sol santral dişi etkileyen çift diş olgusunun tedavisi anlatılmaktadır. Yapılan klinik ve radyografik muayeneler sonucunda, bu dişin üst sol santral kesici ile süpernumere dişin füzyonundan oluştuğu belirlenmiştir. Çift diş, komşu santral dişin kron boyutunda olacak şekilde ikiye ayrılarak süpernumere diş, ilgili kökle birlikte çekilmiştir. Bir yıllık takip sonunda sol santral kesici dişin vitalitesinin devam ettiği belirlenmiştir. Bu olgu, çift dişin ayrılmasında doğru teşhisin önemli olduğunu ve konik ışınlı bilgisayarlı tomografi (KIBT) tabanlı verilerin komplike olan tedavi planlanmasında oldukça yararlı olduğunu göstermektedir.
