Knowledge about the efficacy and accuracy of motion artifact correction software programs can be beneficial.Objectives: This study aimed to assess the effect of motion artifacts and their correction software on quality and interpretability of CBCT images.Materials and methods: In this ex-vivo experimental study, a dry human mandible was moved mesiodistally and anteroposteriorly by 1 and 3 mm for 1 s by a robot during CBCT scanning. The images were reconstructed by Romexis software, and three observers evaluated the quality and interpretability of images with and without the application of Planmeca CALM™ software for artifact correction. The effects of distance and direction of movement, landmark location, scanner resolution, and application of CALM software on quantitative and qualitative interpretability, measurability, and sharpness of images were analyzed.Results: A high percentage of agreement existed among the three observers in all variables (P < 0.05). Landmark location and direction of movement had no significant correlation with qualitative interpretability, measurability, and sharpness of images (P > 0.05). Distance of movement had a significant effect on qualitative interpretability and sharpness (P < 0.05) but not measurability (P > 0.05) of images. Application of CALM had no significant correlation with qualitative interpretability, measurability, or sharpness (P > 0.05).

Internal echo, convective flow, and Doppler signals were evaluated on US, while on MRI, we measured the apparent diffusion coefficient (ADC).Results: Surprisingly, all lesions (4 LECs and 7 DCs) had hyperinternal echoes. Convective flow and Doppler signals were observed in 2 of the 4 cases of LEC, and the ADC was high in these cases (2.4 × 10-3 and 2.0 × 10-3 mm2/s). In the two cases where they were not, the ADC was low (1.4 × 10-3 and 0.81 × 10-3 mm2/s). Various cells, such as lymphocyte cells, foam cells, erythroid cells, and keratin, have been found in the cystic cavity, which are thought to be the cause of hyperecho. Considering the ADC, the presence or absence of convection and Doppler signals is thought to reflect the ease of movement of the contents. In the DCs, neither internal convection nor obvious Doppler signals were observed. ADCs were quite low for cysts, which was a characteristic finding (1.1 ± 0.13-3 mm2/s).Conclusion: It is well known that DCs appear hyperechoic on US owing to the presence of keratin; however, it is necessary to recognize that some LECs are depicted as hyperechoic masses and have convective flow and Doppler signals depending on the content.","PeriodicalId":56103,"journal":{"name":"Oral Radiology","volume":" ","pages":"467-474"},"PeriodicalIF":1.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143634972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clinicians may be unfamiliar with this lesion. This study aimed to evaluate the clinical and radiographic features of osteomas to aid accurate diagnosis.Methods: Osteomas diagnosed in the oral and maxillofacial region at two dental schools between January 2012 and October 2023 were analyzed. Clinical, radiographic features, and histopathologic variants were evaluated.Results: Twelve patients (8 females, 4 males) with a total of 13 osteomas were identified. Four were central (1 mandibular, 2 maxillary, 1 glenoid fossa) and 9 were periosteal (7 mandibular, 1 maxillary, 1 maxillary sinus floor). Mandibular lesions included 3 in the posterior region, 1 anterior involving the genial tubercle and body, 2 at the angle, 1 at the ramus, and 1 at the condyle. Two maxillary lesions were in the posterior region, and 1 extended from the canine to the molar region with impacted teeth. Central osteomas typically appeared as irregular, dense radiopaque masses with blending borders, whereas periosteal osteomas presented as round/oval or irregular radiopaque masses with well-defined borders. Central osteoma may be difficult to distinguish from fibro-osseous lesions, whereas the diagnosis of periosteal osteoma is often straightforward. Osteomas in the maxilla associated with impacted teeth, the glenoid fossa, and the genial tubercle each represent the fourth reported cases in the literature.Conclusions: Osteomas in the oral and maxillofacial region are rare and may present in uncommon locations.

All M3M were classified into high-risk and low-risk groups based on the degree of contact with the MC observed on computed tomography. The contact classification was evaluated using four machine learning models (Prediction One software, AdaBoost, XGBoost, and random forest), three convolutional neural networks (CNNs) (EfficientNet-B0, ResNet18, and Inception v3), and three human observers (two radiologists and one oral surgery resident).

Among the CNNs, ResNet18 achieved the best performance, with an AUC of 0.83. The human observers exhibited AUC values between 0.67 and 0.80.

We compared the SPECT/CT SUVmax with the Saxon test, MR sialography stage, and histopathological grade to determine the stage of Sjögren's syndrome. We then calculated the cutoff value of SUVmax at pre-stimulation for the parotid glands in the early and late stages of Sjögren's syndrome.Results: The SUVmax for > 2 g per 2 min by the Saxon test was higher than that for ≤ 2 g per 2 min. The SUVmax for MR sialography stages 0-1 was higher than that for stages 2-4. The SUVmax for histopathological grades 0-2 was higher than that for grades 3-4.

Dental age (DA) was calculated and compared to chronological age (CA) using various formulas. Cameriere's formula was used to create a new Egyptian formula specific to the Mediterranean region, and a linear regression model was used to evaluate all morphological variables as well as gender.
