Test specimens were fabricated using acrylic resin (resin), cobalt-chromium alloy (Co-Cr), and Ceria stabilized tetragonal zirconia polycrystal-based nanostructured zirconia/alumina composite (zirconia). Specimens of each material were attached to the upper and lower terminals of a digital force gauge. The operator masticated chewing gum, wiped off any saliva, and placed the gum on the lower specimen. The gum was compressed to a thickness of 1 mm between the upper and lower specimens. Thereafter, traction was applied to the upper specimen at a cross-head speed of 100 mm/min under 3 different conditions (dry, wet with distilled water, and wet with artificial saliva) to determine the maximum adhesive strength of the chewing gum. The statistical analysis was performed using the Bonferroni test after a one-way analysis of variance (α=0.05). Under dry conditions, adhesive force was 14.8±6.8 N for resin, 14.0±4.8 N for Co-Cr, and 4.3±2.3 N for zirconia. Significant differences were noted between resin and zirconia, and between Co-Cr and zirconia. When distilled water was applied to the specimen surface, the adhesive strength was 16.8±1.7 N for resin, 8.3±2.1 N for Co-Cr, and 2.7±0.8 N for zirconia. Significant differences were noted between resin and Co-Cr, resin and zirconia, and Co-Cr and zirconia. When artificial saliva was applied to the specimen surface, the adhesive force was 18.5±2.8 N for resin, 5.3±0.8 N for Co-Cr, and 3.0±1.7 N for zirconia. Significant differences were noted between resin and Co-Cr, and resin and zirconia.

If such a relationship were established, it would simplify and facilitate the prediction and reestablishment of the OVD in the construction of complete dentures. The correlation between the OVD and the length of 2D or 5D has already been investigated in a number of studies. However, to our knowledge, no study has investigated the relationship between the length of 4D and the OVD. A total of 117 adult Sudanese women were enrolled in this study. The distance from tip of the finger to the second crease was measured using a digital caliper. The OVD was established based on two measurements: one from the septum of the nose to the menton of the chin; and the other from the tip of the nose (N) to the gnathion at the tip of the chin (Gn). All data were analyzed using the SPSS program. The Pearson correlation coefficient was used to determine the relationship between variables. Differences between means were determined using a paired-sample t-test. The p-value was set at 0.05. A significant correlation was found between finger length and the OVD. However, this correlation was significantly higher between 2D and the OVD based on N-Gn. The present findings indicate that 2D can be used to predict the OVD in adult Sudanese women.","PeriodicalId":45490,"journal":{"name":"Bulletin of Tokyo Dental College","volume":"57 4 1","pages":"215-221"},"PeriodicalIF":0.5,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2209/tdcpublication.2016-0001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68185635","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}

Here, expression of CK13, 14, 17, and 19 was investigated in a rat model of 4-nitroquinoline-1-oxide-induced tongue cancer during a series of carcinogenetic processes to determine their value in assessing the features of epithelial dysplastic spread around a cancer. Based on tissue conditions, the results showed that expression levels of CK13 and 14 decreased in the order of no change, dysplasia, and cancer, whereas those of CK17 and 19 increased in the same order. Expression of CK13 showed a significant difference among no change, dysplasia, and cancer. This indicates that comparing the immunohistochemical staining profiles of CKs, especially CK13, could help in assessing the characteristics of epithelial dysplastic spread around a cancer.","PeriodicalId":45490,"journal":{"name":"Bulletin of Tokyo Dental College","volume":"57 4 1","pages":"241-251"},"PeriodicalIF":0.5,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2209/tdcpublication.2010-0029","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68184912","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}

Recently, however, dental cone beam computed tomography (CBCT), which provides 3-D images of the maxillofacial region, has enabled dentists to examine patients undergoing endodontic therapy more effectively, improving diagnostic accuracy. Here, we describe a positive treatment outcome achieved using CBCT to diagnose apical periodontitis of the maxillary premolars, which had proven difficult to diagnose based on clinical findings and dental radiography alone. The patient was a 42-year-old Japanese man who presented with the chief complaint of gingival swelling in the maxillary right premolar region. Our initial diagnosis, based on clinical findings and dental X-ray, was apical periodontitis of the maxillary right second premolar, and treatment was started. However, after the patient failed to respond to the treatment, CBCT was performed. Based on these new findings, the diagnosis was changed to one of apical periodontitis of the upper right first premolar, and the patient was treated accordingly. Previous studies have described the complex anatomical morphology of the upper premolars, noting multiple roots and variation in the morphology of the root canals. The 3-D images provided by dental CBCT allow better assessment of oral conditions than the traditional 2-D images provided by dental X-rays, which in turn enables the dentist to better select the most appropriate treatment. Here, the patient showed no symptoms and was progressing well at a 6-month follow-up visit. The present results indicate that when clinical findings and dental X-rays alone are insufficient to allow a secure diagnosis, CBCT offers an effective alternative which will enable the appropriate treatment to be selected more reliably.","PeriodicalId":45490,"journal":{"name":"Bulletin of Tokyo Dental College","volume":"57 4 1","pages":"291-297"},"PeriodicalIF":0.5,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2209/tdcpublication.2016-1900","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68185485","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}

Nitric oxide (NO) is an immune-induced destructive mediator in type I diabetes, and inhibition of its production promotes arteriosclerosis. In this study, lymphangiogenesis and expression of NO synthase (NOS) during the healing process after tooth extraction were investigated immunohistochemically in control (C57BL) and Akita mice as a diabetes model. Between 1, 4, and 10 days after extraction, expression of NOS, vascular endothelial growth factor-C (VEGF-C), VEGF receptor-3 (VEGFR-3), and von Willebrand factor was strongest during the granulation tissue phase. This suggests that severe inflammation triggers regulation of NOS and these other angiogenic and lymphangiogenic factors. During the callus phase, a few days after extraction, induced osteoblasts were positive for VEGF-C and VEGFR-3 in both the control and Akita mice, suggesting that bone formation is active in this period. Bone formation in the Akita group exceeded that in the controls. Bone tissue formation was disrupted under hyperglycemic conditions, however, suggesting that such activity would be insufficient to produce new bone.","PeriodicalId":45490,"journal":{"name":"Bulletin of Tokyo Dental College","volume":"57 3 1","pages":"121-31"},"PeriodicalIF":0.5,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2209/tdcpublication.2016-0600","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68185776","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 combined power of discrimination was greater than 0.9999999999, indicating that this multiplex system is an excellent tool for forensic casework. The allele frequency in the data were weighed against that in four other local populations (Chinese, Iranian, Belgian, and African). The average coefficient of correlation was strongest in the order of Africa (0.092522), Belgium (0.264822), Iran (0.404363), and China (0.706661). These results are consistent with what is known about the anthropological history of and prehistoric human migration in the Malay region.

Periodontal examination revealed multiple sites with a probing depth of ≥10 mm. Radiography showed pro-nounced bone defects in the maxillary incisors and molar region. Real-time PCR was used to detect Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, and Tannerella forsythia in subgingival plaque; all 3 pathogens were found. Based on a clinical diagnosis of generalized AgP, periodontal therapy was initiated, which resulted in an improvement in clinical and microbiological parameters. A modified Widman flap procedure was then performed on sites with residual periodontal pockets. Next, a connective tissue graft was performed for ridge augmentation at #22, which had shown evidence of ridge resorption. Postoperative reevaluation revealed a reduction in probing depth and an improvement in marginal bone levels. Oral function was then restored using a fixed bridge prosthesis and maintenance therapy initiated. The periodontal condition has remained stable over a 2.5-year period. In the present case of AgP, surgical intervention reduced periodontal pockets and periodontal pathogens and improved the architecture of both the hard and soft tissues, allowing subsequent care of the periodontium to be performed efficiently by the patient.","PeriodicalId":45490,"journal":{"name":"Bulletin of Tokyo Dental College","volume":"57 4 1","pages":"259-268"},"PeriodicalIF":0.5,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2209/tdcpublication.2016-1700","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68185471","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}

Here, we describe cases of CL/P treated at our hospital and how such a diagnosis and prenatal counseling are handled. A survey was carried out on 4 cases seen at our department between April 2013 and March 2014. Patients are referred to our department from local or our own obstetrics clinics on a prenatal diagnosis of CL/P based on findings from ultrasonography. If the case is a referral from outside, the patient will first be seen at our own obstetrics department. Our department may then be subsequently requested to provide the parents with prenatal counseling. Effort is made to reassure the parents that postnatal support will be provided, right from the start. Next, the multidisciplinary nature of the treatment process is explained. However, only the essential outline is given at first so as to avoid inducing unnecessary anxiety. A response is also given to any questions the parents may have. Our experience of giving such care leads us to believe that improvements are required in the way that explanations and assistance are provided.
