RADİKÜLER KİST BOYUTLARININ İNCELENMESİNDE KONİK IŞINLI BİLGİSAYARLI TOMOGRAFİ VE ULTRASONOGRAFİ’NİN KARŞILAŞTIRILMASI

Abstract

Radiküler kist, çenelerde en sık görülen odontojenik kaynaklı inflamatuar kisttir. Son yıllarda maksilloofasiyal bölgede bulunan kistlerin incelemesinde sıklıkla konik ışınlı bilgisayarlı tomografi (KIBT) kullanılmaktadır. Ancak vestibül kemiğin inceldiği veya destrükte olduğu durumlarda ultrasonografi (USG) de yardımcı tanı aracı olarak kullanılabilmektedir. Bu çalışmanın amacı radiküler kistlerin USG boyutlarının KIBT boyutlarıyla karşılaştırılmasıdır. Bu çalışmaya, fakültemizde rutin dental muayeneler sırasında fark edilen ve teşhisi patolojik olarak doğrulanan 20 radiküler kist vakası dahil edilmiştir. Çalışmada kullanılan KIBT görüntülerinin tamamı Newtom 5G cihazıyla (FP, Quantitative Radiology, Verona, İtalya) alındı ve USG incelemeleri Aplio™ 500 (Toshiba Medical Systems Corporation, Otawara, Japan) B-Mod ve yüksek frekanslı lineer tarama probları kullanılarak gerçekleştirilmişti. Normal dağılım gösteren değerler için Pearson korelasyon katsayısı, normal dağılım göstermeyen değerler için Spearman korelasyon katsayısı hesaplandı. Lezyonların bukkolingual, meziodistal ve superoinferior boyutları için KIBT ve USG ölçümleri arasında pozitif ve anlamlı korelasyon izlendi. (p<0.01/r:0.912, p<0.01/r:0.857 ve p=0.01/r:0.688). Hem KIBT hem de USG için vestibül kemik kalınlığı ve lezyonların bukkolingual boyutu arasında anlamlı bir ilişki gözlenmedi (p>0.05). İntraosseöz lezyonların incelenmesinde KIBT diş hekimliği alanında sıklıkla kullanılsa da USG, lezyonun boyutlarını güvenilir bir tanı aracı olan KIBT ile korele bir şekilde verebildiğinden intraosseöz lezyonların tanısında yardımcı araç olarak kullanılabilir.

COMPARISON OF CONE BEAM COMPUTED TOMOGRAPHY AND ULTRASONOGRAPHY IN EXAMINATION OF RADICULAR CYSTS DIMENSIONS

Abstract

Radicular cyst is the most common odontogenic inflammatory cyst in the jaws. Cone-beam computed tomography (CBCT) has been increasingly popular in recent years for the assessment of cysts in the maxillofacial region. However, ultrasonography (USG) can also be performed as a secondary diagnostic method in cases with thinned or destructed vestibuler bone. The aim of this study is to evaluate the radicular cysts' USG and CBCT dimensions. This study included 20 cases of radicular cysts that were found during routine dental examinations at our faculty and whose diagnosis was verified pathologically. AplioTM 500 (Toshiba Medical Systems Corporation, Otawara, Japan) using B-Mode and high frequency linear scanning probes was utilized for the USG tests, and all of the CBCT images used in the study were obtained using a Newtom 5G device (FP, Quantitative Radiology, Verona, Italy). Pearson correlation coefficient was calculated for normally distributed values, and Spearman correlation coefficient was calculated for non-normally distributed values. Positive and significant correlation was found between CBCT and USG measurements for the buccolingual, mesiodistal and superoinferior dimensions of the lesions. (p<0.01/r:0.912, p<0.01/r:0.857 and p=0.01/r:0.688). For both CBCT and USG, there was no significant correlation between vestibular bone thickness and the size of lesions in the buccolingual region (p>0.05). CBCT is a widely utilized diagnostic imaging modality in dentistry for the evaluation of lesions in the jaws. However, ultrasonography (USG) can serve as a complementary tool in the diagnosis of intraosseous lesions, given its ability to accurately measure lesion size and its correlation with CBCT findings.
