Tendernesses and mouth opening pains at the region of temporomandibular joints and/or in masticatory muscles are very common on temporomandibular joint disorder patients.<BR>We usually give these patients anti-inframmatory analgesics or muscle relaxants until the treatment plan is decided, or when the splint therapy is ineffective for removing the tenderness or pain.<BR>Recently we have had an opportunity to use a new anti-inframmatory analgesic of arylacetate derivatives, Amfenac Sodium (AMF) to the patients who have temporomandibular joint disorders, and have evaluated the analgesic efficacy, side effect and usefulness of this analgesic.<BR>27 patients aged from 16 to 71 years (severity: mild 11, moderate 14 and severe 2) were given AFM (200 mg/day for 14 days) and evaluated symptoms were spontaneous pain, tenderness, mouth opening pain, interincisal opening range, clickin sound and crepitus at the 7th day and at the 14th day.<BR>As a result, total improvements were as follows: excellent 4 (14.8%), moderate 13 (48.1%), little 9 (33.3%), no change 1 (3.7%).<BR>6 side effects (22.2%) were reported, but those were mild (5 cases), or moderate (1 case). No severe side effect was found.<BR>Consequently, we concluded the usefulness of AMF as followed: very useful 4 (14.8%), luseful 12 (44.4%), relatively useful 10 (37.0%). Total usefulness including very useful, useful and relatively useful was 96.2%.

908 Japanese dry skulls (3-84y) were investigated its masticatory parts about sex dimorphism. They were not cured their caries and defect of teeth.ResultsMale condylar breadth and M. masseter origin length were wider than these of female in over 20 years old groups, and were caused by their functional discrimination. Edentulous group reduced their breadth and length, especially in condylar breadth. Old edentulous group indicated morphological non-sexual dimorphism. Male number of loss of teeth were same as female. Attrition showed functional discrimination between male and female, but we could not clearly that of causes. Bite relation of anterior teeth were pointed out their sex differences, and results of attrition were under consideration, we thought that the teeth application or use differed between male and female. It was caused by functional decline and effect of sex hormones that old female edentulous showed reduction of condylar breadth and M. masseter origin length.

Six cases with severely atrophic edentulous alveolar ridges, in which subperiosteal tissue expander (STE) was used before ridge augmentation with hydroxyapatite-tricalciumphosphate compound (HA-TCP) particles, were presented. In many cases, full inflation of the STEs could be achieved immediately after insertion thereof. One week after full inflation of the STEs, implantation of HA-TCP particles was performed. At that time, relatively firm subperiosteal envelopes were observed. Since the envelopes prevented migration of the particles, secondary vestibuloplasty due to loss of depth of the vestibule was not necessary except for one case that reguired removal of denture fibrosis. In all cases, functional and stable ridges were formed. As for complications, one patient had unilateral paresthesia of the lower lip and another had perforation and dehiscence.

The purpose of this study is to investigate the features of maxillofacial bone fractures due to sports accidents, because few detailed cases in the literature could be found.Sixty patients hospitalized for treatment in the department of oral surgery, Nagoya University Hospital in the period 1967-1988, were analysed.The incidence of this group among all facial bone fractures was 14.7 %, and sex ratio ofonset was 14: 1 with male predominance. By age distribution, the highest occurence was in the 20-29 age group. The incidences of soft tissue traumas complicated with fractures and multiple fractures by sports accidents were less than by other causes.In conclusion it appears that sports-related maxillofacial fractures are less serious than the injuries due to other causes.For prevention of sports injuries it is necessary to investigate the individual factors of every fractures and the concept of “Sports Dentistry” must be established.

Fourteen patients with subcutaneous emphysema treated in our department during 17 years were clinically studied. All but one were referred to us by other dentists because of complications. They con sistedof five male and nine female patients. Their ages ranged from 16 to 67 years and 62% of them were in their thirties. The emphysema resulted during sectioning of the mandibular third molar by using an air-turbine handpiece in four patients and from extraction of other teeth in four patients. The use of compressed air during dental procedures was the cause in four patients and the complication was associated with endodontic treatment and implanta tionof a dental implant in the other two patients. A diffuse swelling involving the eyelid, cheek, mandibu larregion and neck accompanied by crepitation on palpation of the swollen area was noted in all patients.Difficulty in opening the eyelid, headache, nausea and mediastinal emphysema were found in four, one, one and one patients, respectively. Antibiotics were given to all patients to prevent infection. Except four one patient with prolonged swelling due to pericoronitis and another patient without adequate information, the swelling with subcutaneous crepitus tended to subside within a week and secondary complications were encountered in no patients.

Traumatic facial emphysema is rare in facial trauma. There are various case reports regarding this kind of injury and the route of air intrusion. For diagnosis and treatment, the cause of traumatic facial emphysema must first be considered. We report three cases of traumatic facial emphysema. The first patient, a 16-year-old male, had buccal swelling caused by a facial bruise, and he was diagnosed as having buccal emphysema. The second case, a 21-year-old male, had palpebral swelling and double vision after suffering a facial bruise, and he was diagnosed as having palpebral emphysema. The third case, a 37-year-old male, suffered from double vision and orbital swelling, and he was diagnosed as having orbitopalpebral emphysema accompanying a fracture of the orbital floor. With conservative non-surgical treatment, these symptoms were improved.

石油系合成高分子等の従来型素材は,その多くが原料を枯渇資源に頼り,生産工程でも膨大なエネルギーを必要とする。大量生産・大量消費・大量廃棄型経済から脱却し,持続可能な社会を実現するための切り札として注目されている素材が「クモの糸」をはじめとする「構造タンパク質」である。鋼鉄の340倍の強靱性(タフネス)を誇る「クモの糸」などの構造タンパク質は,環境性と超高機能性を両立する次世代基幹素材の本命として実用化が期待されているが,工業化に向けた技術的ハードルが極めて高く,産業的に未開拓である。メーカーが本素材を用いて開発を進めようにも,製品開発ができるレベルでのサンプル供給を行なえるサプライヤーが存在しなかったことが,その主な要因であった。私たちは,2004年より慶應義塾大学先端生命科学研究所にて本研究開発に取り組みはじめ,その研究成果をもとに2007年にスパイバー株式会社を設立,量産化のための基本となる要素技術を確立し,2013年11月NEDOからの支援を受け,世界で初めて製品開発ができるレベルでのサンプル供給が行なえる試作研究施設「PROTOTYPING STUDIO」を立ち上げた。また,2014年には,我が国成長戦略の要となる次期基幹産業創出を目指したハイリスク・ハイインパクトな研究開発課題を国家的に支援するための内閣府主導「革新的研究開発推進プログラム(ImPACT)」において,「超高機能構造タンパク質による素材産業革命」として本研究課題が採択されたことで,今後鶴岡サイエンスパークを拠点とする研究開発体制が大幅に増強される見通しである。また,2期連続で採択を受けたNEDOプロジェクトにて,これまでの知見を総動員した次世代型パイロットラインを建造中であり,今春頃の竣工を目指している。これにより,本格的にメーカーとのアプリケーション開発のための試作検討を開始できる見込みである。今後,人類がタンパク質を工業的に素材として使いこなせる時代を切り拓き,本素材を一日も早く社会に普及させるべく,ImPACT等の活用によりさらなる研究開発の推進を図るとともに,戦略的にパートナー企業とのアライアンスを進め,構造タンパク質素材の世界初の工業化の実現を目指す。最終的には世界の合成高分子の20%程度を構造タンパク質素材に置き換えることができる可能性があると試算しており,関連産業を含めれば数十兆円規模の巨大なマーケットポテンシャルを秘める。本プロジェクトは,石油化学が中心であった工業材料に,「構造タンパク質素材」という新たなカテゴリーを創造し,枯渇資源に頼らない持続可能な社会の実現に大きく貢献するものである。本講演では,私たちのこれまでの取り組みや,組織としての特徴,今後の展望等について発表できる範囲で概説する。

The effectiveness of zinc replacement therapy is reported to be approximately 70%. However, the effectiveness of this therapy in our department has been lower than that reported in the field of otolaryngology. In the present study, we examined the effectiveness of zinc replacement therapy in patients with taste disorder. Forty patients were administered only zinc formulations(Polaprezinc, 150mg/day) for ≥8 weeks. The time until effect, serum zinc level and other parameters were used to evaluate improvement in the taste disorder. In the present study, three cut-off values were determined based on the serum zinc levels.The overall improvement rate among the patients in this study was 50%. The improvement rates by serum zinc level were 57% at <60μg/dl, 56% at 60-69μg/dl, 60% at 70-79μg/dl, and 14% at ≥80μg/dl. There was a significant difference in the improvement rate between the patient groups with serum zinc levels of <80 and ≥80μg/dl(57% vs. 14%, p<0.05). The times until effective expression in the 20 subjects with improvement were less than 2 months in 20% and more than 2 months in 80%, with significant differences among the two groups(p<0.05). Polaprezinc was effective in 60% of the cases where serum zinc level measured in blood tests was less than 80μg/dl. Effectiveness was not observed when the serum zinc level was more than 80μg/dl. Therefore, zinc supplementation therapy should be conducted over the long term after proper selection of the patients.

The purpose of the present study was to clarify the anatomical basis of the cranio-and maxillofacial rehabilitation using implants. In the present study, 30 cadavers from the dissection room were evaluated. In particular measurements of the craniofacial bones, including height, width, and thickness of the cortical bone were performed. The results were as follows:1. Orbital areaIn the lateral and superior orbital rim of the placement site of implant of orbital prosthesis, the maximal thickness of the inner and outer sides was 16.0 mm, and the minimum was 9. 2 mm. The maximal thickness of the width was 11.1 mm and the minimum was 6. 8 mm. The maximal thickness of the cortical bone was 2.5 mm, and the minimum was 2.1 mm.2. Temporal bone1) At the placement site of the implant of an auricular prosthesis, the maximum thickness of the width was 10.4 mm, and the minimum was 2. 8 mm. The maximum thickness of the cortical bone was 3.7 mm, and the minimum was 3.7 mm.2) At the placement site of the bone anchored hearing aid, the thickness of the inner and outer sides was 8.6 mm. Thickness of the cortical bone was 3.0 mm.3. Frontal and nasal boneIn the center of the frontal and nasal bone, the thickness of the inner and outer sides was 19.3 mm. The thickness of the coronal bone was 3.0 mm.4. MaxillaThe thickness of the inner and outer sites at the site 1 of the maxilla (5 mm distal to the center) was 13 mm. The thickness of the width at site 1 was 10. 1 mm. Tne thickness of the cortical bone at site 1 was 1.4 mm.From these results, the anatomical basis on the cranio-and maxillofacial rehabilitation using implants could be clarified.

We report a case of long-term (about 10 years) limited mouth opening following a bilateral transtemporal approach for multiple cerebral aneurysms. A 41-year-old man with limited mouth opening was referred to our clinic for treatment. At the first visit, his maximum mouth opening distance was 13 mm between the upper and lower incisors and there were palpable indurations at the bilateral temporal muscles. We diagnosed this situation as a contracture of muscles, and performed bilateral coronoidectomy under general anesthesia. Mouth-opening exercises were started from one day postoperatively, and continued for 7 months. His maximum range of mouth opening is now maintained at 30 mm.

The greatest care must be paid in discussing a possible cause of temporomandibular joint disorders because there were sexal difference and changes with aging in the masticatory structure as described in Part 1. The purpose of this part is to clarify the sexal difference and changes with aging of the temporomandibular bone surface and to elucidate the effect of masitication on the temporomandibular bone changes.Results: Bone changes frequently occured at the lateral side of the condyle, lateral and central sides of the eminence and in a central part of the anterior slope of the eminence. Old females showed a higher score of changing than males with a significant difference between them. Molar or posterior tooth defect had an influence on the condyle and temporal component changes in the young. Progressed attrition with aging influenced on the changes of the temporal component bone surface in males. The temporomandibular joint in males showed a relative stability from the end of growth period to 30 years of age, but females showed no stability throughout the life including growth period. Edentulous changes were caused by aging and loss of teeth so long as this study concened.

In the diagnosis of HIV-infection, it is essential to carry out the check test after a screening test. If saliva can be used for this check test, the test is far safer to perform than a blood test. To investigate the potential for diagnostic misjudgment due to non-specific reactions, differences from the blood test, and the reliability of the check test, saliva samples from 20 HIV infected patients, 29 false-positive risk patients, and 34 healthy volunteers were checked via the test. Similarly, the relationship between this check test and the result of the ELISA method of Orasure using saliva was investigated.By means of the test using saliva (the WB method), all HIV infected patients were detected as positive, while all healthy volunteers were shown to be negative. Regarding the false-positive risk patients, both saliva samples from the two persons detected as false-positive via the ELISA method using saliva were shown to be negative by this check test.The rate of appearance of non-specific bands for healthy volunteers and false-positive risk patients by the WB method was 42.2% in saliva samples, and 64.7 % in blood samples, indicating a higher rate of appearance in blood samples, relative to saliva samples. The molecular weight of most non-specific bands present in the saliva samples was approx. 80kDa, and bands corresponding to P25 and P18 were detected with high frequency in the blood samples. In 15 saliva samples from the false positiverisk patients, which were simultaneously inves tigatedusing the ELISA and WB methods, non-specific bands were detected in 6 samples, which were shown to be negative by the ELISA method, and in 2 samples, which were shown to be false positive by the ELISA method. In 6 of those 8 samples, bands with a weight of approx. 80kD were detected. In the measurement of pure saliva samples, bands with a weight of approx. 80 kDa were detected in 6 of 8 samples, only in parotid saliva. Circadian change in the non-specific reaction was demonstrated in 4 of 6 samples, which were immediately supplied from patients after a meal. All of these non specificreactions, however, had no effect on the results regarding diagnosis of HIV infection. Furthermore, no new band was detected in saliva samples to which a high-concentration of intra-oral microbe had been added. These results suggest that the HIV antibody test by salivasamples is a sufficiently reliable test.

Amyotrophic lateral sclerosis (ALS) is a progressive neuromuscular disease that affects both upper motor neurons and lower motor neurons.Here is a case of ALS with predominantly bulbar involvement. The patient is a 63-year-old male. He was referred to the Department of Oral Surgery, Kurume University School of Medicine with chief complaints of inability to speak clearly and difficulty in eating. On oral examination, atrophy and muscular fasciculation in the tongue were found. There was no loss of aberrations in taste. Except for dysphagia and masticatory disturbance. he had no difficulty practicing his profession. Subseqently, he was diagnosed by the neurologist as having progressive bulbar palsy (PBP) in a motor neuron disease.When the onset of ALS is predominantly bulbar in origin, the patient may first consult a dentist because of the oralfacial symptoms of dysphagia, dysarthria, masticatory disturbance, and muscular weakness. It is important for the dentist to recognize a motor disability and to control the condition without neglecting the nature and severity of the disease.
