Thus the present study aimed to, immunohistochemically, evaluate the presence of these lymphocytes in rabbit gingival tissues after the replacement of Cenobone. This experimental one way blinded study was performed on 20 gingival tissues gathered from disease-free rabbits with or without bone powder, respectively groups A and B. Immunohistochemical envision method was performed for mapping CD4 lymphocytes. The number and intensity of staining were compared between groups in 5 consequent HPF without overlap with the light microscope in connective tissue. Data were analyzed by Fisher exact test, Wilcoxon, and chi-square statistically in SPSS20 software. The number of CD4 T cells was higher in group A compared to group B.(P=0.02) Pattern of distribution in connective tissue did not show a difference between the two groups. (P=0.41). Results of the present study might confirm the role of CD4 T in an allergic reaction to bone powder material and suggest this cell as a useful factor for the prediction of allergic reactions in the first weeks of surgery. Further studies in this field are required.","PeriodicalId":11858,"journal":{"name":"ENVIRO Dental Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87743046","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}

Comparative cross sectional study. Dental department of operative dentistry, LUMHS, Jamshoro Sindh, Pakistan, from December 15-12-2014 to June 15-6-2015. A total of 160 single rooted teeth with intact clinical crowns have been collected. Using human blood, the teeth were discolored. With the vita shade guide, shades of discolored teeth were taken. Each tooth was handled with the root canal. 2 mm of root-canal-filling material cleaned under the junction of cement-enamel. In addition, it was then coated with glass ionomer cement 1 mm thickness. Teeth were divided randomly into two groups based on bleaching content used in the pulp chamber; group-A (C.P): 16% Carbamide-peroxide. Group-B (S.P): tetra-hydrate sodium-perborate mixed with distilled water. After 21days, the results were checked for efficacy. The analysis included a total of 160 teeth extracted (80 teeth extracted in each group). In group A, 78 (51.7%) found effectiveness compared to 73 (48.3%) in group B. The experimental groups showed statistically similar bleaching results at the end of twenty one days and p value found to be not significantly different (p=0.078). With a significant result, intracoronal bleaching of non-vital colored teeth is less invasive, comparatively safe and effective to remove the staining of non-vital discolored teeth.","PeriodicalId":11858,"journal":{"name":"ENVIRO Dental Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85366553","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}

A conventional complete denture is utmost usually used treatment modality for these patients. A few studies assessed the quality of life of patients before as well as one month after complete denture therapy. This study aimed to assess the consequence of complete denture therapy on oral health-related quality of life of edentulous patients. This study was conducted on 43 edentulous patients in 2018-2019 who met the inclusion criteria. After obtaining their written informed consent and ethical approval from the university’s medical ethics committee, patients were requested to fill out the standardized Persian version of the oral health impact profile-14 (OHIP-14) questionnaire before as well as one month after the delivery of complete denture via an interview. Data were analyzed using SPSS version 21 via the Wilcoxon and MannWhitney U tests. The total score of quality of life (OHIP-14) of patients considerably improved after treatment (P<0.001). The quality of life of patients significantly improved in all domains (P<0.001) except for functional limitation (P=0.122) and physical pain (P=0.009) domains, which had a more favourable status before the denture delivery. The difference in OHIP-14 total score of patients was significant regarding sex and age before (P=0.004 and P=0.006, respectively) and after (P=0.022 and P=0.007, respectively) denture delivery. Edentulous patients showed an improvement in oral health related quality of life at one month after denture delivery.","PeriodicalId":11858,"journal":{"name":"ENVIRO Dental Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75656838","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}

Selenomonas noxia is an anaerobic, motile, non spore-forming, gram-negative rod that has been repeatedly associated with periodontal disease and other disorders, including obesity. Based upon the paucity of evidence regarding oral prevalence, the objective of was to evaluate S. noxia prevalence by sampling saliva from the oral cavity to screen for this pathogen. Using an existing saliva repository, DNA was isolated and screened using quantitative real-time polymerase chain reaction (qPCR). Demographic analysis of study samples and qPCR results was also performed. Approximately half of the samples (n=96) were derived from females (51%) and the majority were from Hispanic patients (62.5%). Following DNA isolation and qPCR screening 37.5% (n=35) were found to harbor S. noxia DNA, which was more prevalent among the samples derived from adults (n=22 or 22.9%) than pediatric patients (n=13 or 13.5%). This study provides novel information regarding the oral prevalence of S. noxia among both pediatric and adult populations from a dental school population. These data are an important part of the overall epidemiologic analysis of this organism and may provide some initial information regarding the risk for periodontal or other health issues related to the presence among these populations.","PeriodicalId":11858,"journal":{"name":"ENVIRO Dental Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83901019","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}
