Amaç: Perikoronal radyolüsensiler rutin dişhekimliği
muayenelerinde yaygın patolojik bulgulardır. Dentigeröz kist en yaygın
patolojik perikoronal radyolüsensi ve aynı zamanda odontojenik keratokist (OKC)
yaygın ve yüksek nüks gösteren agresif bir lezon olduğundan dolayı, bu
lezyonların radyografik özellikleri panoramik radyografi ve konik ışınlı
bilgisayarlı tomografi kullanılarak tartışıldı.

Gereç
ve Yöntem: Bu kesitsel vaka serisi çalışmasında 2008-2013 yılları
arasında Mashhad / İran'da özel maksillofasiyal radyoloji merkezine veya
dişhekimliği fakültesine sevk edilen 56 hastanın radyolüsent perikoronal
lezyonunun dentigeröz kist veya OKC'nin histopatolojik sonuçları ile çenelerde
görüldüğü radyografileri iki maksillofasiyal radyolog tarafından ayrı ayrı
incelendi. Her iki gözlemci de patoloji sonuçlarının farkında değildi.
Lezyonlar, yerleri, çevresi ve çevreleyen yapılar üzerindeki etkisine göre
değerlendirildi. Elde edilen veriler tanımlayıcı tablolar kullanılarak analiz
edildi.

Bulgular: 56 hastada 56 lezyon tespit edildi. 20 OKC ve 36
dentigeröz kist vardı. Dentigeröz kistlerin ve OKC'lerin çoğunluğu posterior
mandibulada ortaya çıkmış ve iyi kortekslenmiş bir sınır göstermiştir. OKC
olgularında dış kök rezorpsiyonu daha yüksekti. Ek olarak, burun zemini,
mandibuler kanal, bukal ve lingual korteks (genişleme şeklinde) gibi çevreleyen
yapıların (diş hariç) yer değiştirme eğilimleri, korteks, burun zemini veya
sinüs duvarlarının tahrip edilmesi, OKC'de dentigerous kistten daha yüksekti.

Sonuçlar: Bu çalışmada, diş
yer değiştirmesinin haricinde, çevre yapılara etkisi ile ilgili diğer
parametreler OKC'de dentigeröz kistten daha yüksek dağılım gösterdi.

A BRIEF RADIOGRAPHIC REPORT FROM TWO COMMON ODONTOGENIC CYSTS IN JAWS WITH FOLLICULAR RADIOLUCENT APPEARANCE

Öz

Objectives:
Pericoronal radiolucencies are common pathologic
findings in regular dental checkups. Since dentigerous cyst is the most common
pathologic pericoronal radiolucency and as odontogenic keratocyst (OKC) is a
common cyst also and an aggressive lesion with high recurrence, radiographic
features of these lesions were discussed in this study using panoramic
radiography and cone beam computed tomography.

Materials
and Methods: In this
cross-sectional case series study, radiographs from 56 patients who were
referred to  a private maxillofacial
radiology center or  dentistry faculty in
Mashhad/Iran from 2008 to 2013 in which radiolucent pericoronal lesion was
observed in jaws with histopathologic results of dentigerous cyst or OKC were
separately examined by two maxillofacial radiologists. Both observers were
unaware of pathology results. Lesions
were assessed based on their location, periphery, and impaction on the surrounding structures. Then, obtained data
were analyzed using descriptive tables.

Results: 56 lesions were
identified in 56 patients. There were 20 odontogenic keratocyst and 36 dentigerous cysts.
The majority of dentigerous cysts and OKCs occurred in the posterior mandible
and showed a well corticated border. External root resorption was higher
in OKC cases. In addition, displacement tendency of surrounding structures
(other than tooth) such as nasal floor, mandibular canal, buccal and lingual
cortex (in the form of expansion) as well as destruction of cortex, nasal floor
or sinus walls was higher in OKC than in dentigerous cyst.

Conclusion: Except of tooth displacement other parameters related to the
effect on surrounding structures in this study showed higher frequency in OKC
than dentigerous cyst.
