OBJECTIVES: The aim of this study is to evaluate position and relationship
between adjacent anatomic structures of impacted third molar and canine and pathological
alterations associated with these teeth with cone beam computed tomography (CBCT)
and in the light of the obtained data to raise awareness in clinicians so as to
determine prevalence of these features, decide appropriate management of
impacted teeth and avoid possible complications in surgical operations.

METHODS: In this study, 316 impacted third molars and
canines were examined on 200 CBCT images. Impacted third molars and canines
were assessed according to position, resorption of adjacent tooth and cyctic
lesion. Impacted mandibular third molars were examined relationship with
mandibular canal, impacted maxillary third molars were examined relationship
with maxillary sinus.

RESULTS:
Most of impacted teeth were in mandible. All
impacted canines were in maxilla. Mostly mandibular third molars were impacted
mesioangular, maxillary third molars were impacted distoangular, the canines
were impacted mesial-palatally position. 52% impacted mandibular third molars
had no bone tissue between mandibular canal. Impacted maxillary third molars
had no bone septa between maxillary sinus and they were localized border of the
maxillary sinus frequently. Only impacted canines caused resorption of the
adjacent teeth.

CONCLUSION: Impacted teeth that influenced extensive population
on the world is a common problem. In order to determine appropriate management
of impacted teeth and avoid complications that may occur during or after treatment,
localization and relations with adjacent anatomic structures of impacted teeth
should be evaluated in detail.

AMAÇ:
Bu çalışmanın amacı; gömülü üçüncü molar ve kanin
dişlerin lokalizasyonlarını, komşu anatomik yapılarla ilişkilerini ve bu
dişlerle ilişkili patolojik değişiklikleri KIBT ile değerlendirmek ve elde
edilen veriler ışığında; bu özelliklerin prevalansını saptamak, tedavi
planlamasının belirlenmesinde ve cerrahi operasyonlarda olası
komplikasyonlardan kaçınmak amacıyla klinisyenlerde farkındalık oluşturmaktır.

YÖNTEM:
Çalışmada 200 hastadan alınan KIBT görüntülerinde
316 gömülü kanin ve üçüncü molar diş incelendi. Gömülü üçüncü molar ve kanin
dişlerin pozisyonları, komşu dişlerin kök veya kronunda rezorpsiyon oluşturup
oluşturmadığı, gömülü dişlerin follikülünde kistik değişimin olup olmadığı,
mandibular üçüncü molarların mandibular kanalla, maksiller üçüncü molarların
maksiller sinüsle olan ilişkisi değerlendirildi.

BULGULAR:
Gömülü molarların çoğunluğu mandibuladayken, gömülü
kanin dişlerin hepsi maksilladaydı. Mandibular üçüncü molarların çoğunlukla
mezyoanguler, maksiller üçüncü molarların çoğunlukla distoanguler, kaninlerin
ise çoğunlukla mezyopalatinal pozisyonda gömülü olduğu saptandı. Gömülü
mandibular molar dişlerin %52’sinde mandibular kanalla gömülü diş arasında
kemik dokusunun olmadığı belirlendi. Gömülü maksiller üçüncü molar dişlerin
çoğunluğunda maksiller sinüsle arasında kemik septa olmadığı ve dişin maksiller
sinüs sınırında olduğu tespit edildi. Komşu dişte rezorpsiyona neden olan
dişlerin hepsi gömülü kanin dişlerdi.

SONUÇ:
Gömülü dişler dünya üzerinde geniş bir populasyonu
etkileyen yaygın bir problemdir. Gömülü dişlerin uygun tedavi yönteminin
belirlenmesi, tedavi esnasında veya sonrasında meydana gelebilecek
komplikasyonların önüne geçilmesi için gömülü dişlerin çene içerisindeki konumlarının,
komşu anatomik yapılarla olan ilişkilerinin ayrıntılı olarak değerlendirilmesi
gerekir.
