Evaluation of Mesiodentes: A Retrospective Study by Cone-Beam Computed Tomography

Abstract

Background:  Mesiodens is the most common type of supernumerary tooth and located in the palatal midline between the two maxillary central incisors. The aim of this study was to evaluate the distribution of mesiodens according to shape, position, and the complications in cone-beam computed tomography (CBCT) images.

Methods: This study was carried out retrospectively on CBCT images of cases. The following data were recorded: age, gender, shape (conical, incisor, tuberculate, round), direction (vertical, semi-vertical, horizontal, inverted), position (impacted or erupted), any pathologies or complications (delayed eruption of adjacent tooth, root resorption, cystic formation, diestema, displacement of adjacent tooth) and relation to neighboring anatomical structures (nasal cavity, nasopalatine canal).

Results:  Age distribution of the patients ranged from 7 to 61 years; mean 16.2 years. The results showed that; mesiodentes were observed in the form of cutter tooth (38.5%) mostly, followed conical shape (33.8%). A majority of the mesiodens were in vertical direction (38.5%) and impacted (92.3%) in CBCT images. Thirty-six patients (72%) had one mesiodens, 13 patients (26%) had two, and only one case (2%) had three mesiodentes. The most common complication was delayed eruption (29.2%). No complications were found in 49.2% of the cases. Sixteen cases (24.1%) were associated with nasal fossa, while 43 cases (66.1%) were associated with nasopalatine canal.

Conclusion: Radiographic examination, especially CBCT images, is important for exact diagnosis, evaluation and management of mesiodens.

Mesiodenslerin Değerlendirilmesi: Konik Işınlı Bilgisayarlı Tomografi ile Retrospektif Bir Çalışma

Abstract

Amaç: Mesiodens, supernumerer dişlerin en yaygın türüdür ve iki maksiller orta kesici diş arasındaki palatal orta hatta yerleşmiştir. Bu çalışmanın amacı, mesiodenslerin şekil, konum ve komplikasyonlara göre dağılımını konik ışınlı bilgisayarlı tomografi görüntüleri (KIBT) ile değerlendirmektir.

Gereç ve Yöntemler: Bu çalışma, olguların KIBT görüntülerinin retrospektif olarak incelenmesi ile yapılmıştır. Kaydedilen veriler; yaş, cinsiyet, şekil (konik, kesici diş, tüberküllü, yuvarlak), yönü (vertikal, semi-vertikal, horizontal, ters), pozisyonu (gömülü ya da sürmüş), herhangi bir patoloji veya komplikasyon oluşturup oluşturmaması (komşu dişin gecikmeli sürmesi, kök rezorpsiyonu, kistik oluşum, diestema, komşu dişin yer değiştirmesi) ve komşu anatomik yapılarla (burun boşluğu, nasopalatin kanal) ilişkisi.

Bulgular: Hastaların yaş dağılımı 7 ila 61 yıl arasında olup ortalama yaş 16.2 idi. Elde edilen sonuçlara göre; mesiodenslerin çoğunlukla kesici diş (% 38.5) ve konik şekilli (% 33.8) olduğu tespit edildi. Mesiodenslerin en sık görülen yönünün vertikal yön (% 38.5) olduğu ve büyük çoğunluğunun gömülü (% 92.3) kaldığı görüldü. Otuz altı hastada (% 72) bir mesiodens, 13 hastada (% 26) iki tane, bir vakada ise üç mesiodens (% 2) vardı. En sık görülen komplikasyon gecikmeli sürme (% 29.2) idi. Olguların % 49.2'sinde herhangi bir komplikasyon görülmedi. On altı olgu (% 24.1) burun boşluğu, 43 olguda (% 66.1) ise nazopalatin kanalla ilişkiliydi

Sonuç: Radyografik inceleme, özellikle KIBT görüntüleri, mesiodenslerin kesin tanısı, değerlendirmesi ve tedavisi için önemlidir.
