GÝRÝÞ ve AMAÇ: Bu çalýþmanýn amacý, ameloblastoma (AB) ve odontojenik keratokist (OKK) olgularýnýn konik ýþýnlý bilgisayarlý tomografi eþliðinde radyolojik özelliklerini karþýlaþtýrmaktýr.
YÖNTEM ve GEREÇLER: 2014-2020 yýllarý arasýnda Kocaeli Üniversitesi Diþ Hekimliði Fakültesine baþvurmuþ, histopatolojik olarak ameloblastoma veya keratokist tanýsý almýþ olgularýn verileri retrospektif olarak incelenmiþtir. Lezyonlarýn lokalizasyonu, radyolojik görünümü, komþu diþlerde kök rezorpsiyonu ve deplasman varlýðý, gömülü diþ ile iliþkisi, kortikal kemikte ekspansiyon ve perforasyon varlýðý, tedavi biçimi ve rekürrens oranlarý kayýt ve analiz edilmiþtir.
BULGULAR: 10 AB ve 13 OKK olgusu deðerlendirilmiþtir. AB grubundaki hastalarýn yaþ ortalamasý 39,5 (16-64 arasýnda) iken, OKK grubundaki hastalarýn yaþ ortalamasý 42,3 (21-68 arasýnda) olarak tespit edilmiþtir. AB olgularýnýn %90’ýnýn, OKK olgularýnýn ise %84’ünün mandibula posterior bölgede lokalize olduðu gözlenmiþtir. AB’nin istatistiksel anlamlý olacak þekilde OKK’ye göre daha fazla kök rezorpsiyonuna, diþ deplasmanýna ve kortikal kemik ekspansiyonuna ve perforasyonuna sebep olduðu tespit edilmiþtir (sýrasýyla; p=0,002, p=0,006, p=0,005, p=0,007). Ancak, lezyonlarýn radyolojik görünümü, gömülü diþ ile iliþkisi ve rekürrens oranlarý arasýnda istatistiksel olarak anlamlý bir farklýlýk saptanmamýþtýr (p>0,05).
TARTIÞMA ve SONUÇ: Birbirine benzer radyolojik özellikler gösteren bu iki patolojik oluþumun ön taný sürecinde ayrýmýnýn yapýlmasý zor olabilmektedir. AB ve OKK’nin çevre kemik ve dentisyonda meydana getirdiði deðiþiklerin bilinmesi; yaklaþým ve tedavi sürecinin yönlendirilmesi açýsýndan klinisyene yardýmcý olacaktýr.

INTRODUCTION: The aim of the presented study was to compare the radiological feautures of ameloblastoma (AB) and odontogenic keratocyst (OKC) cases by using cone-beam computed tomography.
METHODS: The data of patients with a histopathological diagnosis of ameloblastoma and keratocyst between 2014 and 2020 were retrieved from the archives of Kocaeli University Faculty of Dentistry, and investigated retrospectively. The localization, radiological appearance, presence of root resorption and tooth displacement, association with impacted tooth, presence of cortical bone expansion and perforation, treatment method and recurrence rates were recorded and analyzed.
RESULTS: 10 ABs and 13 OKCs were retrieved. The mean age of the patients in AB group was 39.5 (ranging from 16 to 64), while the mean age of the patients in the OKC group was 42.3 (ranging from 21 to 68). 90% and 84% of all AB and OKC cases were localized in the posterior region of the mandible, respectively. Root resorption, tooth displacement, bone expansion and perforation were significantly greater in ABs compared to OKCs (p = 0.002, p = 0.006, p = 0.005, p = 0.007, respectively). However, no statistically significant difference was found between lesions in terms of radiological appearance, association with impacted tooth and recurrence rate (p> 0.05).
DISCUSSION AND CONCLUSION: Differentiation of these lesions which exhibit similar radiological characteristics can be challenging. A thorough knowledge of AB and OKC with respect their effects on the surrounding bone and dentition will help the clinician for management and planning of the treatment procedure.
