    Nine-week-old male Wistar-strain rats were used, corresponding to adulthood in human beings. Calcium deficiency and low calcium diet were fed for 3 weeks, followed by activated Vitamin D_3 for 1 week, and standard diet for another 3 weeks. The effect on formation of bone matrix was investigated, and results were as follows. 1. Body weight No significant differences were revealed among the three groups after 7 weeks of study. 2. Radiographic findings and bone density Calcium deficiency group showed thinner width of interosseous and medial cortice than control group. Bone density showed no significant differences among the three groups. 3. Histopathological findings Bone matrix of diaphyseal cortex was shown densely distributed in control group, inner and outer circumferential lamellae thick, and Haversian system well-formed. Calcium deficiency group showed such findings of bone loss as decreased width of outer circumferential lamellae, decreased Haversian system number, and cavitated osteocytic lacunea. Formation of bone matrix in low calcium group was shown almost the same as in control group. 4. SEM findings Many osteocytic lacunae were seen on superficial layer of interosseous and medial cortice in control group, collagen fibers and deposition of calcifying vesicles were present. Calcium deficiency group showed no significant differences morphologically compared with control group, but the bone contour showed small. Osteocytic lacunae showed indistinct borders with the from surrounding matrix, and irregular-shaped resorptive lacunae were seen. In low calcium group, no changes were found in interosseous and medial cortice compared with control group. The regular-arranged collagen fibers were seen in bone formative layer, the collagen fibric network got dense in superficial area. 5. Hematologic findings Electrolytic, biochemical, and endocrinological examinations showed no significant differences among the three groups. From the aforementioned results, combined treatment with calcium-containing dietary and activated Vitamin D_3 helps with the improvement of bone structure in bone loss resulting from calcium deficiency, as long as bone formation is normal until the adulthood with standard diet feeding. With low calcium diet, bone metabolism was shown to function well, and resulting bone matrix formation almost the same as control group.

    私たちは, 口腔扁平上皮癌38例における血清TNF-αを測定し, その有用性を検討した.口腔扁平上皮癌患者の血清TNF-αの測定値は健常成人よりも有意に高い値を示していた.また, 予後不良例に比べ, 予後良好例では有意に高い値を示し, 5年生存率でも血清TNF-α陽性例が有意に高い成績を示していた.さらに, 血清TNF-αはSquamous cell carcinoma antigen (SCCA), Immunosuppressive acidic protein (IAP)の腫瘍マーカーと相関していた.以上の研究成績から, 口腔扁平上皮癌において, 血清TNF-αは重要な予後因子であるとともに, 腫瘍マーカーとして臨床的に意義あるものと考えられた.

    我々は1989年からネパール王国テチョー村を中心に, 歯科保健医療に関する学術調査と国際協力を継続している.最近の活動は疾病対策からPrimary Health Care方向へ重点を移してきている.そういった観点から, 本研究では村人の健康と直結する生活用水の水質調査を実施した.テチョー村は, 首都カトマンズ近郊の農村で, 人口は約11, 000である.村では朝と夕1時間ずつ共同水道施設で給水があるが, その水だけでは不足がちであり, 溜め池の水やと湧き水も体や食器の洗浄や衣類の洗濯に利用されており, 衛生上の問題があると思われる.そこで本調査では, 水道の水源, 水道施設, 溜め池, 湧き水, 家庭内の貯水容器などから採取した24の検水について, 一般細菌, 大腸菌群, カドミウム, 水銀, 鉛, 砒素, 六価クロム, シアン, 硝酸性窒素及び亜硝酸性窒素, カルシウム硬度, pHの項目の検査を実施した.検査項目は我が国では水道法に基づいた遵守義務のある「基準項目」から「健康に関する項目」として基準値が定められているものを主に選んだ.水道水は次亜塩素酸処理により十分滅菌されていたが, 水源, 溜め池, 湧き水にはいずれにも大腸菌が検出された.また, 全ての検水で砒素が検出され, 特に湧き水と溜め池の水ではかなり高い値を示した.カルシウム硬度は基準値よりは低かったが, 硬水に属するものであった.他の項目については基準以下か, 検出されなかった.これに加えて, カトマンズより車で約4時間の山奥のアネコット村の飲料水も5検体検査した.山奥ゆえ比較的安全と考えられていたが, やはり, 大腸菌群と砒素が検出された.今後の検討課題としては1)水道水の残留塩素の測定, 2)砒素の精密測定, 3)比較的高いカルシウム硬度と腎臓結石や胆石などとの関連, 4)本調査時は乾季であったが, 雨季ではどうかということ等が挙げられる.

    The purpose of the present study was to investigate the relationship between the presence of the tension ridge and the severity of periodontal disease and the morphological characteristics of the dentition. Thirty seven patients with and without periodontal disease were recruited from the pool of the patients. The following clinical parameters were recorded by a single dentist ; probing pocket depth (PPD), probing attachment level (PAL), bleeding on probing (BOP). In addition, 14 series of dental radiographs, oral photographs, and the study cast impression were taken at the initial examination. The patients were classified into four groups in accordance with the presence of the tension ridge and the severity of the periodontal disease. Four groups constituted T(+) I ; patients who had the tension ridge in conjunction with moderate to severe periodontitis, T(-) I ; patients who did not have the tension ridge in conjunction with moderate to severe periodontitis, T(+) II ; patients who had the tension ridge in conjunction with healthy to slight periodontitis, and T(-) II ; patients who did not have the tension ridge in conjunction with healthy to slight periodontitis. Comparison was made among the groups as to PPD, PAL and BOP. PPD and PAL in palatal site of maxillary premolar, canine and incisor, and those in buccal site of maxillary incisor showed greater values in T(+) I as compared with T(-) I. BOP in palatal site of maxillary premolar, canine and incisors, and those in buccal site of maxillary premolar showed greater values in T(+) I as compared with T(-) I. There was no statistically significant difference between T(+) II and T(-) II in the PPD and BOP. Furthermore, the measurments of the study casts were compared among the groups. The width of the dentition showed no statistical difference between any two groups. The vertical length between central incisors and first molars in T(+) I was longer than that in T(-) I. These results indicated that the patients who had tension ridge in conjunction with periodontitis showed local progression of the periodontitis and the typical morphological characteristics of the dentition. For the diagnosis and the treatment planning of the periodontitis for the mouth breathers, these findings may provide useful information.

    The general expectation of patients who come in for orthodontic treatment is not only to obtain a good occlusal relationship but also to achieve a certain level of esthetic improvement. Therefore, contemporary orthodontic treatment has to take facial structures and varieties into consideration. Consequently this experiment was based on previous research on most preferable profiles, and we once again, conducted survey the preference of people concerning the non-preferable profiles. The followings are the results of this survey. 1. The least preferable profiles are the ones with lips deficiencies (lip retraction and protrusion). 2. Among assorted types of lip deficiency, protruding lips are the least favored. 3. This was the choice of all those tested among all groups of profiles. The results of survey are in accordance with those of previous survey on ideal profiles.

    Tooth preparation of veneer crown is a very important step in prosthodontic treatment. The following basic principles are necessary to fabricate the esthetic form and good fit of veneer crown. 1. Have a good grasp of the restorative from before tooth preparation. 2. Prepare in your mind for the ideal form preparation. 3. Use the air turbin exactly. 4. Use magnifier to prepare. 5. Select the instrument that is suitable for the form preparation. 6. Prepare fully on labial tip part of abutment tooth. 7. The end of shoulder type is more lingual than conntact point. 8. Don't undercut when shoulder type is prepared. 9. Prepare smooth finishing line and clear margin cervical part. 10. Don't make outline of abutment tooth too sharp.
