EVALUATION OF IMPACTED THIRD MOLAR AND CANINES WITH CONE BEAM COMPUTED TOMOGRAPHY

Abstract

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.

GÖMÜLÜ ÜÇÜNCÜ MOLAR VE KANİN DİŞLERİN KONİK IŞINLI BİLGİSAYARLI TOMOGRAFİ İLE DEĞERLENDİRİLMESİ

Abstract

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.
