Articular disc morphology in closed and open mouth positions was investigated, and classified it into 3 types: no morphological change, change into another morphology, and anteroposterior compression. The morphology of folding was classified into 2 subtypes: superior and inferior convex types. The association between these and other MRI/clinical findings were examined.(1) The morphology of the disc in the closed mouth position was evaluated as biconcave on 397 sides, biconvex on 5, even thickness on 32, enlargement of the posterior band on 54, folding on 82, and other types on 11. It was compared with that in the open mouth position. There was no morphological change on 369 sides, an altered morphology on 45, and anteroposterior compression was noted on 167. The most frequent morphological change was one from biconcave to folding (superior convex), which was observed on 16 of the 45 sides. In patients with no morphological change, the incidence of joint effusion was significantly lower than in those with an altered morphology or anteroposterior compression, and the glenoid fossa was deeper. Concerning clinical symptoms, crepitus was significantly more frequent in patients with anteroposterior compression. There were no significant differences in the incidences of the other symptoms among the 3 groups.(2) There were significant differences in the presence or absence of joint effusion and reposition between patients with superior and inferior convex folding. Briefly, in these patients, joint effusion was more frequent than in those with the other disc morphologies. However, effusion of the superior articular cavity was observed in all patients with inferior convex folding, whereas effusion of the superior and inferior articular cavities was noted in those with superior convex folding. In patients with inferior convex folding, reduction was significantly more frequent than in those with superior convex folding. Concerning clinical symptoms, there were no significant differences between the two groups.The results of this study showed that the condition markedly differed between joints with and without mouth opening-related changes in the morphology of the articular disc, suggesting that this parameter is useful for clarifying the pathogenesis of temporomandibular joint arthrosis, selecting treatment, and predicting the prognosis. 四国歯学会 Shikoku Dental Research 四国歯学会雑誌 0914-6091 27 1 11 25 20140600 read0017493MAEDA/published_papers/15680103 M.

All mucus cysts were of submucosal mass with a smooth border. Ten of 12 cysts contained an anechoic area. Among the 12, 11 had an adjacent hypoechoic zone with blood flow. There were reactive sclerotic or edematous changes outside the cyst wall, caused by the partial extravasation of saliva. This finding was exclusively observed in mucus cysts and would help in differential diagnosis, because most of the cysts with extravasation were difficult to distinguish from solid tumor by physical examination alone.

Out of 159 patients with oral malignancies, 247 abdominal CT examinations were performed for the purpose of scouting DM. During the examination, intravenous contrast enhancement (CE) was performed in 166 examinations. DM were detected in 13 patients (8.2%). DM were found in 6 at administration, and 8 were late DM. Nine DM were detected out of 166 (5.4%) examinations with CE, and 5 were detected out of 81 (6.2%) examinations without CE. In detecting the DM, no improvement was found by CE. DM attacked lungs in 13, mediastinum in 3, liver in 2, paraaortic lymph nodes in 1, chest wall in 1, and vertebra in 1. Only 2 patients with DM were free from cervical metastasis, and the remainder was combined with cervical metastasis, regardless the status of the primary sites. Conclusions: Abdominal CT was useful for detecting DM. Intravenous CE was not necessary for scouting the DM. Patients with cervical metastasis had a high potential for developing DM.

Forty lymph nodes with suspicion of metastatic lymphadenopathy out of 20 patients with oral cancers were served for the present study. We could not judge the presence/absence of the metastasis by routine B mode or power Doppler imaging alone. Out of the 40 lymph nodes, 18 metastatic lymphadenopathies were proved histopathologically. Additionally, 11 lymph nodes out of 8 patients with nonspecific reactive lymphadenopathies were included as the control. The pattern of the circumferential blood flow of the lymph nodes was reviewed by the three-dimensional maximum intensity projection (3D MIP) view that was obtained from 3D power Doppler imaging. They were divided into 4 categories ; linear blood flow, mesh like blood flow, spotty blood flow and no circumferential flow. The spotty flow was almost exclusively found in the metastatic lymph nodes. Its accuracy, sensitivity and specificity, positive predictive value and negative predictive value for detecting metastatic lymphadenopathy were 0.73, 0.44, 0.95, 0.89, and 0.68, respectively. This spotty flow was situated at the marginal portion and/or around the lymph nodes by the analysis of the two-dimensional display. We could not differentiate whether it was arterial or venous flow. As the three dimensional sonographic imaging is the time-consuming technique compared to the routine B mode or power Doppler imaging, we cannot routinely perform it. However, it would play a supplementary role for detecting lymph node metastasis, especially if we cannot judge them by the two dimensional imaging alone.

As most dental material is radiopaque, radiography of a chest or an abdomen allows to see the accidental materials. From 1995 to 2002, 35 radiographic examinations were performed after the accidents at Tokushima University Dental Hospirtal. Mean of accidents was 4.4 cases a year. The incidence was 0.004% in the cumulative numbers of dental examinations. The location of accidental material on the radiography was clearly observed in 18 among 35 cases. Radiography of multiple times was performed 13 in 18 cases in order to confirm the excretion. In 5 cases, accidental materials were not confirmed to excrete. Furthermore, there were many cases in which clinical records about accidents were not described. Present findings indicate that it is necessary to detect precisely the location of accidental materials and that radiographic detection is very important.

The purpose of this study was to investigate whether the bony outlines of anatomical landmarks of the TMJ can be observed in the radiographs of 86 joints. Material and Method: Forty-three patients were examined using lateral panoramic TMJ projection in AZ3000TM rotational panoramic X-ray unit (ASAHI Roentgen Industry Company, Limited, Kyoto, JAPAN). The radiographs of the patients were investigated by two oral radiologists to evaluate whether four sites, postglenoid spine, articular eminence, glenoid fossa and condylar head, could be observed. Results: The condyle could be observed in 100% (86 of 86) of the joints. The postglenoid spine, articular eminence and glenoid fossa could all be observed in 58% (50 of 86) of the joints. Thus all four sites could be observed in 58% of the cases. Bilaterally, all four sites could be observed in 42% (18 of 43) of the patients. Conclusion : In the lateral panoramic TMJ radiographs many of the bony outlines could not be observed. Further study of panoramic TM Jprojection may be needed to solve this problem.

We reported the visibility of bony outlines on lateral panoramic TMJ images with an AZ3000TM rotational panoramic X-ray unit (ASAHI Roentgen Industry Company, Limited, Kyoto, JAPAN) in a previous study (part 4). In this study, we investigated the optimal image layer thickness to improve the visibility of the TMJ images. Material and Method: We altered the AZ3000TM so that we could adjust the width of slit (named AZ3000TU) to change the image layer thickness. The image layer thicknesses at various combinations of the first and second slits were defined with a wire mesh phantom. A tissue equivalent phantom was positioned and the panoramic lateral TMJ projection was taken with different image layer thickness. The phantom shifted 2.5-5mm inside and outside from standard position in the horizontal plane to simulate miss-positioning of the patient using various combinations of the slits. Four sites, postglenoid spine, glenoid fossa, articular eminence and condyle, in the radiographs were evaluated to find out the best slit combination and whether the sites could be observed or not by two oral radiologists. Results: The image layer thickness was 6mm at 1.2/8mm slit combination, 8mm at 1.0/7mm, 11mm at 0.5/5mm and 25mm at standard lateral mode. When the image layer thickness was at 6, 8 and 11mm, the four sites of TMJ were all observed. At 25mm image layer thickness, the mid cranial base superimposed TMJ strongly. In the case of 6mm-image layer thick ness, by positioning the phantom 5mm lateral from the standard position in the horizontal plane the postglenoid spine was difficult to observe in the radiograph. Conclusion: In the radiographs at the standard position where the image layer was less than 11mm, all four sites of TMJ were observed. However, at 6mm image layer thickness (the thinnest), when the object was positioned 5 mm lateral from the standard position, the postglenoid spine was difficult to detect.

However, no standard evaluation method has been established. In addition, the correlation between the condylar position and TMJ internal derangement has not been elucidated. We designed a new, simple evaluation method for the condylar position. Furthermore, the correlation between the condylar position and articular disc displacement was examined. Subjects: A total of 160 TMJs of 80 TMD patients examined by tomography and MRI were included in this study. METHODS: Tomogra-phy was used to evaluate the condylar position in the antero-posterior and supero-inferior direc-tions using our evaluation method as follows; (1) Three segments, the anterior (=a), posterior (=b) and superior (=c) joint spaces as shown by tomography were measured . (2) To evaluate the condylar position, 3 acquired values were substituted for 2 numerical expressions. Each antero -posterior and supero-inferior condylar position was expressed in APR and SIR quantitatively. APR=b-a/b+a× SIR=(a+b/2-c/a+b/2+c)×100 Articular disc positions were evaluated in 3 positions by MRI. The 3 positions were as follows; superior disc position: the articular disc was in the normal position, slightly anterior disc posi-tion: a part of the posterior band of the articular disc was between the articular eminence and condylar head, completely anterior disc position: complete anterior displacement of the articular disc. The differences among the condylar position of the TMJs of the 3 positions were statisti-cally examined. RESULTS: A total of 157 TMJs were quantitatively evaluated in 2 directions. Three TMJs could not be evaluated with this evaluation method. Significant differences were found concerning the anteroposterior direction between the superior disc position and the slight-ly anterior disc position (p=0.021), as well as the superior disc position and the completely anterior disc position (p=0.047). Significant differences were detected in the supero-inferior direction between the superior disc position and the completely anterior disc position (p<0.001), as well as the slightly anterior disc position and the completely anterior disc position (p=0.020). CONCLUSION: A simple and useful method to evaluate the condylar position was designed. A correlation between the condylar position and articular disc displacement was found.

Significant differences were found concerning the anteroposterior direction between the superior disc position and the slight-ly anterior disc position (p=0.021), as well as the superior disc position and the completely anterior disc position (p=0.047). Significant differences were detected in the supero-inferior direction between the superior disc position and the completely anterior disc position (p<0.001), as well as the slightly anterior disc position and the completely anterior disc position (p=0.020). CONCLUSION: A simple and useful method to evaluate the condylar position was designed. A correlation between the condylar position and articular disc displacement was found.

Eleven left temporomandibular joints from 11 dried human skulls were studied. Thirteen images were obtained for each joint, projected from 8° posterior to 52° anterior in 5° steps. The possible structures superimposing the condyle were the eminence from infratemporal crest to sphenoid spine, the eminence from articular tubercle to sphenoid spine, post glenoid process, anterior wall of the external auditory meatus, and mastoid process. None of the structures except mastoid process caused any problem in tracing the contour of the condyle. The part of the condyle with superimposition of the mastoid process was difficult to interpret, and extent of the part spread gradually as the projection angle increased. Nine out of 11 (82%) condyles were not superimposed with the mastoid process when a 30° anterior projection was adopted. This was considered to be the most suitable angle to obtain an anterior-oblique aspect of the mandibular condyle keeping good visibility. 歯科放射線 0389-9705 37 1 41 48 19970605 10.11242/dentalradiology1960.37.41 read0017493MAEDA/published_papers/15680117 Naoki Maeda 前田直樹 Michiko Kubo 久保典子 Hidehiko Hosoki 細木秀彦多根歯の歯根嚢胞 Japanese Society for Oral and Maxillofacial Radiology 特定非営利活動法人日本歯科放射線学会 Dental Radiology 歯科放射線 0389-9705 37 1 56 57 19970605 10.11242/dentalradiology1960.37.56 read0017493MAEDA/published_papers/13730912 Toru TAKEUCHI 竹内徹 Akira TAKAHASHI 高橋章 Chieko SUGAWARA 菅原千恵子 Manabu SHIMOMURA 下村学 Naoki MAEDA 前田直樹 Akihisa TADA 多田章久 Shusaburo UEMURA 上村修三郎 Panoramic Radiography of the Jenporomandibular Joint Part2 : A Study of Horiyontal Optimum Angle of X-ray Beam to Mandibular Condyle パノラマX線撮影装置を利用した顎関節撮影法第二報水平方向の至適X線入射角度の検討 Dental Radiology 歯科放射線 0389-9705 37 1 41 48 19970000 10.11242/dentalradiology1960.37.41 read0017493MAEDA/published_papers/15680120 Hidehiko Hosoki 細木秀彦 Manabu Shimomura 下村学 Michiko Kubo 久保典子 Naoki Maeda 前田直樹 Yasunori Takagi 高木康里 Hirokazu Iwasaki 岩崎裕一 Shusaburo Uemura 上村修三郎 YOSHIHIRO KUBO 久保吉廣 Akihito Tanagami 棚上彰仁放射線治療が影響したと考えられる開口障害を呈した一例特定非営利活動法人日本歯科放射線学会 Dental Radiology 歯科放射線 0389-9705 34 2 134 136 19940630 10.11242/dentalradiology1960.34.134 read0017493MAEDA/published_papers/15680119 Hidehiko Hosoki 細木秀彦 Michiko Kubo 久保典子 Naoki Maeda 前田直樹 Yasunori Takagi 高木康里 Hirokazu Iwasaki 岩崎裕一 Shusaburo Uemura 上村修三郎 Atsushi Suzuki 鈴木温 Maki Hosoki 細木眞紀 Ryutarou Ueda 上田龍太郎 Hisahiro Takeuchi 竹内久裕 Masanori Nakano 中野雅?
