KHE can occur anywhere in the body, but occurrence in the oral cavity is exceptionally rare. The clinical features of KHE are similar to those of oral lesions, such as infantine hemangioma, pyogenic granuloma, and chronic periodontitis. However, unlike other oral lesions, KHE invades neighboring tissue planes and recurs frequently as malignancy. Moreover, some instances of KHE are accompanied by a life-threatening condition named Kasabach-Merritt phenomenon. Correct diagnosis of KHE is very difficult despite its importance. KHE lacks not only specific clinical characteristics, but also distinct imaging findings even with advanced modalities such as computed tomography (CT) and magnetic resonance imaging (MRI). Thus, KHE is often misdiagnosed as another disease. We report a case of KHE in the mandibular gingiva. The enlarged gingival mass showed reddish granulomatous appearance with intact mucosal surface. It was misdiagnosed as another disease and underwent simple resection, but it recurred several times. In radiological examination using periapical radiography, cone beam computed tomography, and magnetic resonance imaging, no specific findings other than ill-defined alveolar bone destruction were observed. The subsequent pathological examination showed CD-31 and CD-34 positive, and D2-40 and HHV-8 negative. This report includes discussion about radiological, clinical, and histopathological features of the lesion and comprehensive literature review.","PeriodicalId":56103,"journal":{"name":"Oral Radiology","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144041649","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}

This scoping review explores possible bone changes due to head and neck pleomorphic adenoma and identifies risk factors for bone destruction.Methods: Articles on bone alterations in head and neck pleomorphic adenoma were searched online using PubMed, Scopus and Scholar, according to PRISMA-ScR guidelines. Only histopathologically confirmed pleomorphic adenomas were included. Extracted data were age, gender, location and size of tumor, duration of symptoms, type of bone erosion and recurrency status.Results: The search resulted in 145 pleomorphic adenomas with adjacent bone alterations. The majority caused expansile bone changes, such as cortex erosion (61.4%) and scalloping (31.0%). Extensive bone destruction was reported in 11 cases (full thickness erosion in 3.4% and bone marrow invasion in 4.1%). Significant risk factors for aggressive bone destruction were tumor size and duration of symptoms (OR = 1.08; 95% CI 1.02-1.14 and OR = 1.03; 95% CI 1.00-1.05).Conclusions: Although mostly bone erosion or scalloping is observed, larger or longstanding pleomorphic adenomas have the capacity of developing more extensive bone destruction, without malignant transformation. However, bone destruction is very rare in pleomorphic adenoma and more likely indicates the presence of malignancy.","PeriodicalId":56103,"journal":{"name":"Oral Radiology","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143774913","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}

Its clinical and imaging diagnoses are often challenging, especially in the early stages, as it mimics jaw cysts and benign tumors, and no specific findings have been identified. This report presents the case of a 66-year-old male patient with mandibular PIOC, highlighting the imaging findings over time. Magnetic resonance imaging (MRI) before symptom onset showed a cystic lesion in the right mandible with a soft tissue component. Both the fluid component and soft tissue exhibited low apparent diffusion coefficient values (1.0 × 10-3 mm2/s and 1.3 × 10-3 mm2/s, respectively). Subsequent MRI approximately 5 months later during symptom onset showed a slight increase in the soft tissue component. Based on the clinical and imaging findings, ameloblastoma was suspected, prompting a biopsy for confirmation. However, the histopathological findings showed squamous cell carcinoma (SCC). MRI performed approximately 1 month later exhibited significant tumor growth and extension beyond the jawbone, consistent with a malignant tumor. Histopathological examination identified areas with a basal layer in a palisading arrangement, indicating a pre-existing odontogenic cyst, and showed a transition from epithelial dysplasia to SCC. In addition, carcinoma cell invasion and proliferation into the cyst were observed. Based on these findings, PIOC of the right mandible was determined to be the definitive diagnosis.","PeriodicalId":56103,"journal":{"name":"Oral Radiology","volume":" ","pages":"302-309"},"PeriodicalIF":1.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142696250","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}

An alveolar bone model without bone defects and models with 12 types of peri-implant bone defects (buccal, circumferential, and mixed types with different widths and depths) were created. A total of 273 images were obtained with orthoradial projections and 10-, 20-, and 30-degree oblique projections using a modified receptor holder. Two observers independently evaluated the images to detect bone defects. The grayscale values (GVs) of the peri-implant region and the adjacent area were measured and compared. The relationship between the GV and the observers' results was examined. The area under the curve (AUC) and inter-observer agreement were calculated.Results: Circumferential and mixed bone defects were detected on the orthoradial projections, while buccal defects were not detected. However, the detection of buccal defects was markedly improved using the oblique projections. In particular, the highest detection rates were obtained using the 20-degree oblique projection. There were no significant correlations between the GV and the bone defect detection rate. The AUCs for the two observers were 0.712 and 0.669. The inter-observer agreement was 0.502.Conclusions: Compared with orthoradial projections, the use of oblique projection images greatly improved the ability of observers to detect peri-implant bone defects on the buccal side. The results provide new evidence for the selection of radiographic images in the follow-up of implant treatment.","PeriodicalId":56103,"journal":{"name":"Oral Radiology","volume":" ","pages":"248-259"},"PeriodicalIF":1.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142980666","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}

While FA has been widely applied in dentistry, there are challenges in standardizing the technique due to factors such as image resolution, region of interest (ROI) selection, and image processing. This study aimed to investigate the impact of the direction of ROI selection (DROIS) on fractal dimension (FD) calculations.Methods: Panoramic radiographs of 226 individuals aged 20-35 years were analyzed. ROIs were selected on the mandibular condyle, angular region, and mental region, and oriented at 0°, 22.5°, 45°, and 67.5° angles. FD was calculated using the box-counting method in ImageJ. The Friedman test and Wilcoxon signed-rank test were used for statistical analysis.Results: The FD values differed significantly between the angled ROI groups in all three regions (Friedman test, p < 0.0001). Pairwise comparisons showed significant differences in FD between most ROI orientations, except between 22.5° and 67.5° in the angular region.Conclusions: DROIS is an important factor that should be considered in FA studies to ensure reliable and reproducible FD values. Appropriate methodological choices can help account for the influence of DROIS on FD calculations..","PeriodicalId":56103,"journal":{"name":"Oral Radiology","volume":" ","pages":"180-189"},"PeriodicalIF":1.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142633388","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}

The aim of this study is to evaluate the MC-MM3 relationship using CBCT and a deep learning technique, as well as to automatically segment the mandibular impacted third molar, mandibular canal, mental and mandibular foramen.Methods: This retrospective study analyzed CBCT data from 300 patients. Segmentation was used for labeling, dividing the data into training (n = 270) and test (n = 30) sets. The nnU-NetV2 architecture was employed to develop an optimal deep learning model. The model's success was validated using the test set, with metrics including accuracy, sensitivity, precision, Dice score, Jaccard index, and AUC.Results: For the MM3 annotated on CBCT, the accuracy was 0.99, sensitivity 0.90, precision 0.85, Dice score 0.85, Jaccard index 0.78, AUC value 0.95. In MC evaluation, accuracy was 0.99, sensitivity 0.75, precision 0.78, Dice score 0.76, Jaccard index 0.62, AUC value 0.88.
