In the interproximal contact areas, probing depth is not accurate because there are some errors in angulating the probe. The purpose of this study was to establish the correct probing method in these areas. Therefore a new interproximal periodontal probe was developed. It eliminated the errors which arise from angulating a probe. The effectiveness of the 8-point method which uses both a conventional probe and the new type interproximal one was determined. The results were as follows: 1. 20 human dry skulls were selected to indicate the necessary angle at which a probe could reach the center of the interproximal contact area. Approximately 30 degrees was needed in molars. This was the most popular angle for measurement in these places. 2. 12 periodontal patients were selected to determine the errors in probing depth between a conventional probe and the new type interproximal one when a probe angulated 30 degrees. The average error was 0.56 mm, indicating that the new type interproximal probe must be used when a probe was angulates 30 degrees. 3. 19 periodontal patients who received a flap operation were selected to determine the effective probing method which could predict the alveolar bone defects in the interproximal contact areas. Measurement of 3 points (bucco-mesial or distal line-angle, linguo-mesial or distal line-angle and center of mesial or distal) could estimate the form of interproximal bone defects. 4. 45 periodontal patients were selected to determine the condition of interproximal periodontal pockets. Marked periodontal damage was present not only at the center of interproximal contact areas but also in the other sites. These results suggest that the new interproximal periodontal probe is a reasonable instrument for angled probing in the interproximal contact areas, and the 8-point method is the most effective one to reveal the periodontal condition in detail.","PeriodicalId":19428,"journal":{"name":"Nihon Shishubyo Gakkai kaishi","volume":"31 2","pages":"608-32"},"PeriodicalIF":0.0,"publicationDate":"1989-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13780424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In four weeks, scaling and root planing were carried out, and time marking was performed by injection of 3 kinds of fluorescent-labeling materials, tetracycline hydrochloride (30 mg/kg), calcein (8 mg/kg), and alizarin complexon (20 mg/kg), intramuscularly. The animals were sacrificed 4 days after the last injection and serial sections without decalcification were prepared. They were examined under a fluorescence microscope and further observed by contact microradiography (CMR) and staining with toluidine blue. According to the observations made by fluorescence microscopy, marked regeneration of the cementum was revealed by each of the 3 labeling agents. Also, the presence of regenerated cementum was supported by the observations by CMR and after toluidine blue staining. In addition, the regeneration of new cementum was shown to start in about 2 weeks after scaling and root planing. Judging from the results of this experiment, the various fluorescent-labeling methods seem to be effective for observing the process of regeneration of cementum.","PeriodicalId":19428,"journal":{"name":"Nihon Shishubyo Gakkai kaishi","volume":"31 2","pages":"633-9"},"PeriodicalIF":0.0,"publicationDate":"1989-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13662352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The measuring apparatus was controlled by a personal computer to obtain the data every 0.1 second. As the GI increased at the site of measurement, higher values were obtained, with longer persistence of the trend of increase in the measured value. 2. In view of the stability of the measured values, the amount of GCF appeared to be best expressed as the value obtained after 10 seconds. 3.

The proximal surface of each treated tooth was designated as the RP surface. The remaining half of the proximal surface was treated with citric acid (pH 1.0) for 3 minutes and was designated as the CA surface. Four untreated teeth served as controls. After 4 weeks, the teeth were extracted, and were processed for light microscopy and for scanning electron microscopy concerning bacterial invasion into the supragingival radicular dentin. The following results were obtained. 1. Radicular cementum was present on most untreated tooth surfaces. However, bacteria were never seen in the dentinal tubules. 2. Bacterial invasion into the dentinal tubules was observed in five of the 10 proximal surfaces (50% of the RP surfaces) and in nine of the 10 proximal surfaces (90% of the CA surfaces). 3. The depth (9.5 +/- 24.1 microns vs 84.6 +/- 136.3 microns) and percentage (0.8 +/- 2.1% vs 20.3 +/- 17.3%) of bacterial invasion in the dentinal tubules of the RP surfaces was lower than that of the CA surfaces. 4.

In addition, the histologic features of bone regeneration associated with their implantation have been evaluated. Very little, however, seems to be known about the effect of implant materials on cementum formation. The aim of this study was to determine whether implant materials stimulate the cementogenesis on adjacent planed root surfaces. Twelve monkeys with healthy gingivae were used in this experiment. Following mucoperiosteal flap elevation, \"windows\" were chiseled in the bone to the proximal root dentin surfaces and adjacent root surfaces were planed. Each of the three implant materials [tricalcium phosphate (TCP), decalcified bone matrix (DBM) and hydroxyapatite (HA)] were then placed in the cuspid and incisor root \"windows\" before the flap was sutured back into the previous position. Windows with no implantation served as a control. Animals were sacrificed 2, 4 and 8 weeks postoperatively. Biopsy specimens including the tooth and surrounding bone were examined by light and electron microscopy. At 2 weeks, all implant particles were surrounded by fibrous tissue. On the other hand, fibrous tissues filled the control defect. On the planed root surfaces after the implantation of TCP and DBM, furthermore, cementoid tissue appeared. At 4 weeks, a considerable amount of new cementum was deposited on the root surfaces except in the implantation of HA. It was especially pronounced after implantation of TCP and DBM which promoted bone regeneration after resorption. These results suggest that resorbable implant materials such as TCP and DBM not only facilitate the formation of new bone, but also of new cementum.","PeriodicalId":19428,"journal":{"name":"Nihon Shishubyo Gakkai kaishi","volume":"31 2","pages":"551-72"},"PeriodicalIF":0.0,"publicationDate":"1989-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13704326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
