Because it is known that collagen is of paramount importance to dental development, and if occurs the interference by addition of destructive agents in their midst this will inhibit tooth morphogenesis.

Preparations were scanned in three dimensions and digitized. Actual MDCA and BLCA values were measured by three-dimensional imaging software. Data were analyzed by Friedman test (α=.05) and pairwise multiple comparisons with the Bonferroni adjustment (α=.0042). \u0000Results: The mean actual MDCA was 10.66 ± 3.96 degrees, compared to visual estimates of 13.86 ± 12.01, 21.94 ± 6.11, and 12.49 ± 8.38 degrees.

The Friedman test resulted in χ2(3) = 68.54 (P<. 05) for MDCA and χ2(3) = 100.07 (P<.05) for BLCA.

Studies have shown that it is produced by gingival cells in periodontal diseases and that its incidence increases with the severity of the disease. The aim of the present study was to investigate the effects of nicotine, cigarette smoke condensate (CSC), and Porphyromonas gingivalis (P. gingivalis) on MCP-1 expression from human gingival fibroblasts (HGFs) in vitro. \u0000Methods: HGFs were exposed for 72 h to 250 µg/mL of nicotine, 100 µg/mL of CSC, 10% P. gingivalis supernatant, P. gingivalis supernatant with nicotine, or P. gingivalis supernatant with CSC. A control group comprised HGFs without any treatment. The conditioned media was then collected for MCP-1 analysis by enzyme-linked immunosorbent assay (ELISA). \u0000Results: There were significant differences in MCP-1 level between the P. gingivalis (p=0.0432) and P. gingivalis with CSC (p=0.0037) groups when compared to the control group. \u0000Conclusions: P. gingivalis stimulates an inflammatory response in periodontal tissues by increasing MCP-1, which helps attract host cells to combat the bacterial infection. Tobacco usage can mask the inflammatory responses normally seen in periodontal diseases by reducing the levels of MCP-1, thus allowing the bacteria to grow somewhat undetected. This could be one factor that explains why smoking is a major contributing factor to the initiation, development, and progression of periodontal diseases.","PeriodicalId":110010,"journal":{"name":"JBR Journal of Interdisciplinary Medicine and Dental Science","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133571387","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}

It has related with self-reaction to the forensic body of each patient as well as the osseointegrated interface. Bone quantity and quality of the implant site may help to define the implant-bone interface, which in turn affects primary stability of the immediate implant placement. Analysis of bone quality prior to surgery provides vital information during treatment planning for dental implant. Additionally, it helps in predicting postsurgical success. The classification of bone quality, however, is difficult to follow clinically, as tactile assessments are subject to the variation among surgeons. Although imaging techniques, such as computed tomography (CT) or cone bean computed tomography (CBCT), are useful to determine bone quality, the exposure to radiation and its precision, are still of concern. This paper reviews common techniques and reference used in dental bone classification as well as the recent reports from histomorphometric analysis and molecular components. It is well acknowledged that clinical awareness of evaluating the amounts of bone surrounding the implant site by appropriate method is critical for a successful outcome.","PeriodicalId":110010,"journal":{"name":"JBR Journal of Interdisciplinary Medicine and Dental Science","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131660154","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}
