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.
