    The accurate diagnosis of vascular anomalies (VAs) is considered a challenging endeavor. Misdiagnosis of VAs can lead clinicians in the wrong direction, such as the performance of an unnecessary biopsy or inappropriate surgical procedures, which can potentially lead to unforeseen consequences and increase the risk of patient injury. The purpose of the present study was to develop an approach for the diagnosis of VAs of the oral and maxillofacial region based on computed tomography (CT), magnetic resonance imaging (MRI) and dynamic contrast-enhanced MRI (DCE-MRI). In the present study, the CT and MR images of 87 VAs were examined, and the following imaging features were evaluated: Detectability of the lesion, the periphery of the lesion, the inner nature of the lesion, the density of the lesion on CT, the signal intensity of the lesion on MRI, the detectability of phleboliths and the shape of the lesion. A total of 29 lesions were further evaluated using the contrast index (CI) curves created from the DCE-MRI images. A diagnostic diagram, which is based on the imaging features of VAs and CI curve patterns, was subsequently extrapolated. The results obtained demonstrated that the VAs were detected more readily by MRI compared with CT, whereas the detectability of phleboliths was superior when using CT compared with MRI. VAs showed a propensity for homogeneous isodensity on CT, whereas, by contrast, they exhibited a propensity for heterogeneous hyperdensity on CE-CT. VAs also showed a propensity for homogeneous intermediate signal intensity when performing T1-weighted imaging (T1WI), heterogeneous high signal intensity when performing short tau inversion recovery MRI, and heterogeneous high signal intensity when performing fat-saturated CE-T1WI. The CI curves of VAs were found to exhibit a specific pattern: Of the 29 CI curves, 23 (79.3%) showed early weak enhancement, followed by a plateau leading up to 400-600 sec. An imaging-based diagnostic diagram was ultimately formulated. This diagram can act as an aid for radiologists when they are expecting to find a VA, and hopefully serve the purpose of simplifying the diagnostic process. Taken together, the findings of the present study indicated that DCE-MRI may be considered a useful tool for the diagnosis of VAs.

    A collision tumor refers to the coexistence of two diagnostically distinct tumors in a common anatomic space. Collision tumors are rare in the oral and maxillofacial region. The present study reported on the case of an 82-year-old female with a collision tumor in the maxillary sinus consisting of small cell carcinoma (SmCC) and squamous cell carcinoma (SCC). Computed tomography (CT) imaging revealed a mass in the right maxillary sinus. The lesion exhibited heterogeneous low signal intensity (SI) on T1-weighted imaging (T1WI), high SI on short T1 inversion recovery and heterogeneous solid enhancement on contrast-enhanced T1WI. The histopathology result of a biopsy specimen confirmed SmCC. After the patient received a course of chemoradiotherapy, follow-up CT revealed a residual tumor. In a second surgery, a remaining tumor and histopathology revealed SCC with no evidence of SmCC. The final diagnosis was a collision tumor made up of SCC and SmCC.

    OBJECTIVES: To examine the diagnostic usefulness and procedures of ultrasonography (US) for mass lesions in the soft tissue of the oral region. METHODS: This study involved patients with mass lesions (tumorous lesions and cysts) who had undergone US and histopathological examinations from January 2017 to December 2019. The following points were evaluated by two observers using an evaluation scale: vascularity, echo intensity level, boundary, margin shape, distribution of internal echoes, and capsule. The usefulness of each point for differential diagnosis of tumorous lesions and cysts was statistically analyzed. RESULTS: Forty-five mass lesions in the soft tissue of the oral region (33 tumorous lesions and 12 cysts) were analyzed. There were significant differences in four evaluation points between the tumorous lesions and cysts: vascularity, echo intensity level, boundary, and margin shape. Cysts were almost completely excluded diagnostically, especially when vascularity was observed. There were also significant differences in two evaluation points between nonvascular tumorous lesions and cysts: echo intensity level and boundary. CONCLUSIONS: In US examination for mass lesions in the oral region, it was possible to diagnose tumorous lesions and exclude cysts when vascularity was observed. When vascularity was not observed, however, tumorous lesions and cysts could be identified using two evaluation points: echo intensity level and boundary.

    Purpose: To focus on the effects of the presence of mesiodens on adjacent teeth and to investigate the timing of its safe removal. Materials and Methods: Cone-beam computed tomography examinations, obtained at Okayama University Hospital over a three-year period, were inspected. Data were recorded including the number of mesiodens; associated abnormalities; and the relationship with neighboring structures. Depending on multiple factors, the risk of developing complications due to early extraction of a mesiodens was divided into three categories: high, medium, and low risk. Results: A total of 5,958 cone-beam computed tomography exams were obtained, 460 patients aged 3-85 years were diagnosed with a total of 568 mesiodens, 382 (67.3%) of which were discovered in young patients (age <10 years), and 333 (87.2%) of these were associated with abnormalities. Regarding the risk categories, 11 (1.9%) were considered to be in the high-risk, five (0.9%) in the medium-risk and 552 (97.2%) in the low-risk categories. Moreover, eight out of 11 high-risk mesiodens were extracted and no post-operative complications have been seen. Conclusion: As the results showed that no postoperative complications were seen in all the extracted cases of high-risk mesiodens, this indicates the possibility of safe extraction at an early age which could reduce related future complications.

    Immune checkpoint inhibitors (ICIs) targeting programmed death ligand-1 (PD-L1) are highly promising therapies for oral squamous cell carcinoma (OSCC). The assessment of PD-L1 expression may help predicting the therapeutic effect of ICIs and, thus, benefit patient selection. Contrast index (CI) parameters derived from dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) have been proven as efficient to assess microvessel density (MVD) in OSCC. The present study aimed to determine the correlation between DCE-MRI parameters and MVD and between DCE-MRI parameters and PD-L1 expression to determine whether DCE-MRI could be used non-invasively to evaluate PD-L1 expression in patients with OSCC. A total of 21 patients with primary OSCC who had undergone a 3T MRI scan, including DCE-MRI, were included in the present study, and CI curve-derived parameters were examined. The MVD and PD-L1 expression in the surgically resected specimens were analyzed using immunohistochemistry (IHC) staining for CD31 and IHC staining for PD-L1, respectively. The results demonstrated that the expression levels of these markers were correlated with DCE-MRI parameters. PD-L1 expression levels were found to be significantly correlated with the maximum CI (CI-max; P=0.007), peak CI (CI-peak; P=0.007), maximum CI gain (CI-gain; P=0.006) and MVD (P=0.001) values. The mean CI-max, CI-peak, CI-gain and MVD values were significantly higher in tumors with high PD-L1 expression (P<0.05). MVD levels were also significantly correlated with the time of CI-max (T-max; P=0.003) and CI-gain (P=0.037). The mean CI-gain was significantly increased, and the mean T-max was significantly shorter in high MVD tumors (P<0.05 and P<0.01, respectively). In summary, the findings from the present study confirmed the correlation between CI parameters, derived from DCE-MRI, and MVD, and suggested that these parameters may be correlated with PD-L1 expression in OSCC tumor cells.

    OBJECTIVES: The purpose of this study was to evaluate the usefulness of Hounsfield unit (HU) assessment with multislice-CT in the differentiation of radicular cysts (RCs), dentigerous cysts (DCs) and odontogenic keratocysts (OKCs). METHODS: In total, 307 odontogenic cysts (RCs, DCs and OKCs) were included in this study. Cysts with lesion diameter <10 mm, cysts with artefacts affecting measurement of HU values, cysts involving infection and recurrent cysts were regarded as exclusion criteria. Images were acquired in three different types of CT scanners: Aquilion ONE, Discovery CT750 HD and SOMATOM Definition Flash. Differences in HU values among scanners and among types of odontogenic cysts were assessed using one-way analysis of variance; multiple comparisons were performed post hoc, using the Tukey-Kramer honestly significant difference test. RESULTS: In total, 164 cysts were analysed in this study (64 RCs, 57 DCs and 43 OKCs). Regardless of the type of lesion, the Aquilion ONE scanner demonstrated a significant difference in HU value, compared with the Discovery CT750 HD scanner. Regardless of CT scanner model, HU values significantly differed between DCs and OKCs (p < 0.0001), as well as between OKCs and RCs (p < 0.0001). CONCLUSIONS: HU values were found to vary among CT scanners and should always be associated with other lesion imaging features while interpreting and elaboration diagnostic hypothesis. Notably, the results suggested that OKCs might be able to be differentiated from DCs and RCs by using HU values.

    The numbers of abnormal findings incidentally detected in adjacent regions are increasing with advances in imaging modalities. The present study aimed to examine the prevalence and characteristics of incidental findings in the thyroid gland on computed tomography (CT) images of the oral and maxillofacial region. CT scans of the oral and maxillofacial region in patients obtained between January 2012 and December 2016 were retrospectively reviewed. Images that revealed incidental findings in the thyroid gland, including nodules, were recorded, together with the sizes and characteristics of the findings. The Japan Association of Breast and Thyroid Sonology (JABTS) guidelines were used for classification. The rate of descriptions of these findings in the radiographic interpretation reports were also examined. Of the 1,135 patients examined, 326 (28.7%) had several types of incidental findings. In particular, 169 (14.9%) of the 1,135 patients had nodules >5 mm in diameter, for which further careful examination is recommended in the JABTS guideline. The description rate for nodules >5 mm in diameter in the radiographic interpretation reports was 30.8% (52/169 patients), of whom 17.3% (9/52 patients) were referred to the endocrinology department for further careful examination. Incidental findings in the thyroid gland were relatively common on CT images of the oral and maxillofacial region. Oral radiologists tend to focus specifically on the oral and maxillofacial region during diagnosis on oral and maxillofacial CT images, but should pay the same careful attention to observe adjacent regions, such as the thyroid gland.

    Adenoid cystic carcinoma (ACC) is a rare epithelial tumor of the head and neck region, and one of the most common malignant tumors of the salivary glands. ACC is a slow-growing tumor characterized by perineural invasion and often has a high-recurrence rate. We describe a case of oropharyngeal ACC invading the mandibular bone through the mandibular foramen that showed a rare pattern of origin and invasion. A 70-year-old woman complained of noise and pain around the right temporomandibular joint. Osteomyelitis was suspected on the initial imaging examinations, although the findings were slightly atypical. However, a mass was observed in the right oropharyngeal wall on subsequent imaging examinations, and mandibular bone invasion, rather than osteomyelitis, was additionally suspected. The mass in the right oropharyngeal wall and right mandible was surgically excised. On postoperative histopathological examination, the mass was finally diagnosed as ACC. As tumor cells were also observed around the inferior alveolar nerve, mandibular bone invasion through the mandibular foramen was suspected. An oropharyngeal ACC invading the mandibular bone through the mandibular foramen is extremely rare. The present case suggests that bone invasion should be considered carefully with several imaging examinations when a malignant tumor such as ACC is observed around the jaw bone.

    Purpose: The prevalence of supernumerary teeth has been reported to be between 0.1% and 3.8%. The aim of this study was to determine the prevalence, clinical significance, and associated pathologies of fourth molars based on a retrospective study and a literature review. Materials and Methods: A 5-year retrospective prevalence study was conducted at the Department of Oral Diagnosis and Dentomaxillofacial Radiology of Okayama University Hospital, Okayama, Japan. The study involved extracting data from the digital records of patients from January 1, 2013 through December 31, 2017. The sampling frame included all patients who had panoramic radiographs, cone-beam computed tomography (CT), and multislice CT images during the period under review. Results: A total of 26,721 cases were reviewed and 87 fourth molars were identified. The prevalence of fourth molars in the 5-year study at Okayama was calculated as 0.32%. The mean age of patients with a fourth molar was 30.43 years, and the male-to-female ratio was 1:0.98. The vast majority of cases were in the maxilla (92%) and had normal shapes (89.7%); furthermore, 82.8% of cases were unerupted. Conclusion: The prevalence of fourth molars in the study population was found to be 0.32%, and fourth molars occurred with approximately equal frequency in males and females. Fourth molars were more common in the maxilla and were predominantly unerupted and small.

    OBJECTIVES: To investigate the correlations among various temporomandibular joint (TMJ) findings on MRI and the relationships between MRI findings and symptoms. METHODS: 425 patients (850 TMJs) with temporomandibular joint disorders (TMDs) who underwent MRI were enrolled. Oblique sagittal proton density-weighted and T2 weighted images in open- and closed-mouth positions were evaluated. MRI findings included disc configuration, disc position, condylar morphology, bone marrow pattern, and joint effusion. Symptoms included TMJ pain, TMJ noise, and limitation of mouth opening. For statistical analyses, Spearman's rank correlation coefficient and logistic regression analysis were applied. RESULTS: Folded disc, disc displacement without reduction (DDWOR), and osteophytes had significant negative correlations with other normal MRI findings (p < 0.01). DDWOR and marrow edema were associated with TMJ pain. Conversely, osteophytes [odds ratio (OR): 0.52; 95% CI (0.30-0.90)] and combination-type condylar degeneration [OR: 0.45; 95% CI (0.24-0.83)] were associated with decreased risk of TMJ pain. Condylar flattening was positively associated with TMJ noise [OR: 5.25; 95% CI (1.44-19.07)] and negatively associated with limitation of mouth opening [OR: 0.34; 95% CI (0.11-0.99)]. High-grade joint effusion was significantly associated with TMJ pain and noise. CONCLUSIONS: DDWOR and high-grade joint effusion (an indicator of inflammation in the articular cavity) were associated with TMD symptoms. This finding suggests that treatment strategy for DDWOR and decreasing inflammation might lessen clinical TMD symptoms. Condylar degeneration was not associated with indicators of inflammation or TMJ symptoms. These results suggest that patients with TMD symptoms should undergo initial MRI to allow rapid selection of appropriate therapies.

    The number of significant incidental findings identified on radiographic examinations has increased. In total, 169 patients, 87 males and 82 females, with a mean age of 67.3 years (range, 17-92 years), as well as 65 patients (38.5%), 43 (66.2%) female and 22 (33.8%) male had abnormal findings in the thyroid for one year in our institution. Thyroid nodules are the most common incidental findings on oral and maxillofacial evaluations. Computed tomography (CT) and magnetic resonance imaging (MRI) examination are frequently used to detect thyroid abnormality. The present study reported a case of papillary thyroid carcinoma (PTC) detected following CT and MRI examination of a mandibular lesion. The CT examination of the oral and maxillofacial region included the thyroid, which must be examined carefully to detect various diseases, including PTC. Collaboration between radiologists and clinicians is important to manage these incidental findings.

    Contrast-enhanced (CE)-MR image is useful to distinguish cystic and solid portions on multilocular lesion, however, the CE-MR examination is contraindicated in patients with kidney disease. Fluid-attenuated inversion recovery (FLAIR) image is one of methods which signal of fluid is suppressed. This study investigated qualitatively and quantitatively whether FLAIR images were useful for detecting and differentiating cystic and solid portions of multilocular ameloblastomas. We retrospectively reviewed 11 cases of multilocular ameloblastoma. FLAIR and short Ti inversion recovery (STIR) sequences were performed in all cases. CE-MR images in 10 cases, and T1-weighted images (T1WI) in 7 cases. FLAIR, STIR, CE-MR, and T1WI images were visually evaluated (qualitative analysis). Signal-to-noise ratio (SNR) of cystic and solid portions were measured and compared among the images of all sequences (quantitative analysis). FLAIR imaging could detect cystic portions with very low SI in all cases because cystic fluid was well suppressed on the images, and the solid portion showed intermediate SI. On some STIR images, the solid portion was masked by the markedly high SI of the cystic fluid. CE-T1WI and CE-FLAIR images showed no enhancement of the cystic portion but enhancement of the solid portion. On FLAIR image, SNR of solid was higher than cystic portion (p < 0.05). Cystic and solid portions of a lesion could be detected and distinguished on FLAIR imaging. FLAIR images are thus useful for diagnosing multilocular ameloblastoma when CE-MR cannot be performed.

    腫瘍の増殖能や転移能に関与する生体内分子を標的とした陽電子断層撮影法(PET)のプローブを作製し、腫瘍の機能的な病態を画像上で予測することを目的とした。実験動物には7週齢BALB/cAJcl-nu/nuヌードマウスを用いた。PETプローブの作製、PET撮像および画像解析、ガンマカウンターを用いた%ID/g tissue値の計測、上皮成長因子受容体(EGFR)発現の免疫組織学的検討を行った。その結果、頭頸部癌に用いられる抗癌剤であるセツキシマブを89Zrで標識したものをPETプローブとして用いることで、EGFRの発現を可視化し、頭頸部癌のセツキシマブ感受性の評価を画像上で非侵襲的に行うことが可能となった。放射性核種の選択によっては、診断のみならず治療に応用できる可能性が考えられた。臨床応用を考える際には、放射性核種の半減期やプローブの代謝経路を考慮し、腫瘍部位以外での被曝についても検討していく必要があると考えられた。

    It is known that the magnetic resonance (MR) imaging features of dentigerous cysts (DCs) are the same as those of other cysts. The cavities of DCs generally show low signal intensity (SI) on T1-weighted imaging (T1WI). However, in our experience, DCs often show high SI on T1WI, rendering them difficult to distinguish from keratocystic odontogenic tumors (KCOTs). In this study, we evaluated seven cases of DC and 23 cases of KCOT to assess whether MR imaging can provide additional information for the differential diagnosis of DC and KCOT.Two trials were evaluated. The first trial was an analysis of the cystic cavity SI on T1WI. To compare the SI between patients, we performed T1WI with contrast (T1c). The second trial analyzed the SI uniformity (U (I )) pound on T1WI, T2-weighted imaging (T2WI), and short inversion time inversion recovery (STIR) images of the cystic cavity, because it has been reported that an MR imaging feature of KCOT is heterogeneous SI. Statistical analyses were performed using the Mann-Whitney U test and a receiver operating characteristic (ROC) curve.The T1c values of DCs were significantly higher than those for KCOTs. The U (I ) pound values on T1WI and STIR images were significantly higher for DCs than for KCOTs. The T1c cutoff values (0.66 and 0.84) and U (I ) pound cutoff values for T1WI (82.1 %) and STIR images (79.8 %) were determined from the ROC analyses.T1c and U (I ) pound values provide useful additional information for the differential diagnosis of DC and KCOT.

    身元確認のための個人識別法の一つとして歯科所見によるものがあり、遺体の口腔内から得られた治療痕などの記録を生前情報と照合することで身元確認を行 う。本研究では、近年急速に普及している死後CTを利用し、画像上の金属アーチファクトを解析することで、口腔内の治療に用いられた材料を類推する新たな個 人識別法の開発を目的としている。また、この方法では、死後CTデータから口腔内の情報を得ることができるため、遠隔地からの個人識別の可能性を提示するも のである。
    2021年度における研究計画では、2020年度までに作製を行なったファントムと、金属6種(チタン、パラジウム、コバルトクロム、銀合金、白金加金タイプ3、白金加金タイプ4)および非金属6種(硬質レジン、コンポジットレジン、ハイブリッドレジン2種、セラミック2種)の計12種の歯科材料の円柱を用いて、画像撮影ならびに解析を行う予定であった。
    しかしながら、各歯科材料の収縮率や円柱の作製方法の違いにより、それぞれの歯科材料の断面の形態にわずかな差異が生じてしまい、2020年度に作製したファントムでは全ての歯科材料について画像撮影ならびに解析を行うことは困難であった。2021年度は、金属6種(チタン、パラジウム、コバルトクロム、銀合金、白金加金タイプ3、白金加金タイプ4)および非金属1種(セラミック1種)についてのみ撮影を行なった。また、本年度は撮影できなかった非金属種5種(硬質レジン、コンポジットレジン、ハイブリッドレジン2種、セラミック)についても撮影できるようファントムを新たに作製した。

    2021年度の研究計画における到達目標は,「識別能の確認と問題点の抽出・解決法の提案」,であった.
    蓄積されたデータから成る生前資料データベースと,若干の形態変化を加えた仮想死後データを作成し,実際に照合を行うことで識別能の程度を検討するため,まずは生前資料データベースとなる相同モデル化データの作成,蓄積に着手した.相同モデル化する際には,STLデータとテンプレートの位置合わせを正確に行う必要があるが,口蓋部分のみでは位置合わせの指標となるレファレンスポイントの設定数が少なくなり,作成した相同モデルの再現性が非常に悪いものとなった.STLデータを使用して作成する相同モデルの形態再現性は後の照合作業の精度に大きくかかわるため,形態再現性を担保するための代替案として,歯槽骨を含む既存の相同モデルから口蓋部分を抽出する手法を考案した.歯槽骨を含む相同モデルを作成する場合はレファレンスポイントが多くなるため,形態再現性が高くなるものと考えられ,本手法を採用することとなった.
    作成した相同モデルは口蓋部分のみの場合と比較し,大きなものとなるため,研究に必要な部分のみとなるよう,不要な部分を除外する必要がある.照合に用いる口蓋の範囲を決定には,形態変化の程度による識別能の変化を考慮することと,当初の目的である無歯顎の場合にでも対応できるよう,歯槽骨領域を除外することとした.照合に用いる口蓋部分の抽出作業はコンピュータ画面上で手動にて行うこととした.
    社会実装を想定した際の本研究課題の問題点である,相同モデル作成の標準化(テンプレート,基準点,STLデータ画一化)と相同モデル作成に要する処理時間,画像・統計処理用PCのスペック等の詳細な検討は次年度以降に行うこととなった.

    Cetuximab (brand name: Erbitux) is an anti-epithelial growth factor receptor (EGFR) targeted anti-cancer drug. In Japan, it was approved for squamous cell carcinoma of the head and neck in 2012. Cetuximab binds to EGFR, inhibits receptor function, and exhibits an anticancer effect. The mechanism of resistance of new anticancer drugs via extracellular vesicles has been clarified. Therefore, we also reached the idea that extracellular vesicles might be involved in the resistance to cetuximab exhibited by oral cancer cells, and examined the mechanism of resistance to cetuximab mediated by extracellular vesicles secreted by cavity cancer cells.

    Forensic individual identification is important in times of major disaster. We focused on mandibular angle as dental individual identification. The purpose of this study was to investigate the correlation between the mandibular angle obtained by three-dimensional reconstruction of CT images taken for medical use and the age.
    Mandibular angle between mandibular base and mandibular posterior edge is obtuse in neonates. The angle of the mandibular angle gradually became acute, showing 110° to 125° in adults, and it was predicted that the angle would become obtuse again with age thereafter. However, no clear results were obtained in this study. It is presumed that the individual differences are too large.

    This research subject is to develop a new method in personal identification and to examine its potential and usefulness. The dental plaster model, which is produced and discarded in large quantities at the dental clinic, is used as a reference material, and a homology modeling theory that makes it possible to compare shapes numerically is applied as a reference method. The image data was processed under the optimal conditions and the discrimination ability was examined. It was confirmed that this method has a good discrimination accuracy. Although there are issues for social implementation, this research has been highly praised by domestic and international conferences, and further development is expected in the future.

    Cetuximab is a monoclonal antibody targeting epidermal growth factor receptor (EGFR), and is effective for tumors with overexpression of EGFR. It was originally used for metastatic colorectal cancer, but since the overexpression of EGFR is seen in 80-100% of head and neck cancer (HNC), antitumor effect is also expected in HNC. In this study, we have assessed the antitumor effect of Cetuximab treatment using 9 oral cancer cell lines, with regard to BRAF, KRAS, NRAS, PIK3CA mutation status. We found no mutation in the mutation hot spots of BRAF gene , KRAS gene, NRAS gene. We also evaluated 5 well-known hot spots of PIK3CA gene, E542K and H1047R mutations of PIK3CA gene were observed in Ca9-22 and HSG cells. BALB/c-nu mouse transplanted with PIK3CA mutated HSG cells showed in lower sensitivity for Cetuximab. The results suggest that E542K mutation of PIK3CA could be used as a screening test to evaluate the sensitivity of HNC to Cetuximab.
