Indiana Cephalometric Analysisの紹介
Get PDFapplication/pdfThe Indiana Cephalometric Analysis was introduced. Our Orthodontic Department plans to apply this analysis for Japanese samples. The value of this analysis is based on including the several measurements directed to growth prediction because the forecast of growth for diagnosis and treatment planning is not generally used as the teaching materials of post-graduate students in our country. Besides, this analysis is of potential value to develop more practical orthodontic planning from growth prediction like the Ricketts' method of the Visualized Treatment Objectives.journal articl
Experimental Production of Lingual Tumor by Jet Injection of 9, 10-dimethyl 1, 2-bemzamtjracene
Get PDFapplication/pdfNinety-six male golden hamsters, 3 months of age, were injected with a 0.25% solution of 9, 10-dimethyl 1, 2-benzanthracene in acetone into the tongue at weekly intervals using a Panjet injector (Panjet^[○!R]: Wright, G. E.). Thirty hamsters surviving for six months or longer after initiation of the carcinogen injection were subjected to observation. By the llth week of experiment, the lingual mucosa became slightly hypertrophic and whitish in patches. Around the 24th week, nearly 80% of the animals were found to have formation of nodules in the lingual mucosa. After the 35th week of treatment the nodules grew in size of showed a papillary growth in occasinal animals. Histopathologically, there were seen dysplasia (11 animals), dysplasia with epithelial down growth (7 animals), papilloma (7 animals), carcinoma (3 animals), hemangioma (1 animal), neurilemmoma (1 animal).journal articl
口腔領域における化膿性炎からの検出菌について : 最近1年間の検討
Get PDFapplication/pdfAlthough serious infectious diseases have been decreased by means of the wide use of antibiotics, occurrence of opportunistic infection and increase of resistant bacteria have come serious problems. In order to reveal the species of organisms detected from oral infectious diseases, we investigated the 54 patients examined by the Department of Oral and Maxillofacial Surgery II, Matsumoto Dental College in the last one year. Some of the results were as follows. 1. Out of 35 cases in whom organisms were detected by needle aspiration, mixed infection were found in 27 cases (77.2%), and infection with anaerobes in 17 cases (48.6%). 2. Among 88 strains of organisms detected from the 35 needle aspirated cases, α-hemolytic streptococcus, anaerobic gram-negative rods and β-hemolytic streptococcus consisted 26.2%, 14.8% and 9.1%, respectively.journal articl
歯科教育における技術適応能力診断の方法論的研究 第5報 松本歯科大学衛生学院生徒のCPI年度的推移とYG性格検査について
Get PDFapplication/pdfIn dental medicine, being an excellent member of society is required as much as being skilled in medical technics. The following reports were made: First Report: The technical ability and the skill ability of the students in Dental Hygienist and Technician School, Second Report: About the California Psychological Inventory (CPI), Third Report: A comparative study of the technical ability and the result from CPI, Fourth Report: Annual change of technical ability and skill ability. On this report, the annual changes in CPI, and also in YG Character test, between the freshman of Dental Hygienist and Dental Technician School in the year of 1980 and 1981 were compared. Furthermore, we made another comparison in CPI and YG between each classes. Results were as follows: As for the annual change of CPI in 1980 and 1981, a small change was seen in each 18 grades but almost no change was seen in each group. The particular feature of the changes in each class was the upward tendency in Sp (Social Presence), AI (Achievement via Independence), Ie (Intellectual Efficiency), Fx (Flexibility) seen in the 2nd graders of Technician Class. It was believed that this tendency owed to the education based on technical skill, consequently making the students inured to studies. Another feature was the upper tendency of Cm (Communality) in Hygienist Class contrasting with the downward tendency in Technician Class. It was considered that the upper tendency in the former class was an effect from personal relationship in clinical practice, and the downward tendency in the latter class might be, for one reason, because of its special field as a technical practice which compeled the technicians in a closed circumstances.journal articl
口腔内の色彩に関する研究 第7報 Micro-Color-Computerによる陶歯の色(2)TRUBYTE-BIOFORM, SHOFU-REAL陶歯
Get PDFapplication/pdfAfter the sixth report, measurement on other shade-guide was tried. In this report TRUBYTE-BIOFORM and SHOFU-REAL teeth were selected to achieve the experiment. This time, we were able to reform every color tone of the teeth accurately without being troubled about the previous problems; the surface gloss and the microstructure. But it was found out that as the position of the radiation detector gets far from the source of radiation, the difference in color would decrease (and so would a VITA-LUMIN). From this fact, considering that the distinction of color is easily perceived, it was affirmed that the best method for measuring was placing the radiation detector 1～3mm far from the tip of the source of radiation.journal articl
松本歯科大学に於ける初診患者の数計的観察(昭和52, 53, 54年度)
Get PDFapplication/pdfMatsumoto Dental College greeted the 10th year of its foundation. Clinical practice for students started from 1977 is in the fifth period. The number of the first consultation patients in 1977, 1978 and 1979, was analyzed. Results were as follows: (1) The numbersof the first consultation patients were 4,325 in 1977; 4,404 in 1978 and 4,015 in1979. (2) Patients were comparatively many in June, and a slight decrease in April and December. (3) Regarding to the age, patients in 0 to 10 year-old were the largest number, and 21 to 30 year-old was the second and 31 to 40 year-old was the third. (4) The largest number of the first consultation was in pedodontics, the second was in oral surgery, and the third was conservative dentistry. The next was prosthetic and orthodontics. The number of dividend patients of periodontal disease and preventive class had decreased.journal articl
