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.
