The knowledge of imaging features of these two methods about intraosseous jaw lesions is important for dental radiology. Purpose:The aim of this study is to evaluate artificial mandible intraosseous lesions by using CBCT and USG. Materials and Method:In this in vitro study, intraosseous lesionscontaining water, milk, olive oil, and liver were evaluated in 60 artificial mandibles by using CBCT and USG.Lesion sizes were compared between CBCT and USG. Lesion sizes were measured on the anterior-posterior, bucco-lingual, and superior-inferior sides. Hounsfield unit (HU) values of the lesions in CBCT images were compared between different materials. Echogenicity of the lesions were evaluated in USG images. One sample t and one-way Anova tests were used for the statistical analysis of the study (p ˂ 0.05). Results:In all size measurements of the lesions, mean CBCT values were statistically higher when compared with USG. In CBCT images, statistically difference was found between the HU values of lesions containing olive oil and other lesion contents. In USG images, echogenicity of water, milk and olive oil was found to be anechoic and the echogenicity of liver was found to be hypoechoic. Conclusion:CBCT was found to be more accurate than USG in measurement of the size of mandibular intraosseous lesions. According to the results of our study, it was thought that only oil content could be differentiated by using CBCT HU values.It was found that lesions with liquid and non-liquid contents could be differentiated with their echogenicity difference in USG images.
