Self-administered questionnaires were used to obtain information regarding knowledge of oral health and habits. Dental caries status was scored according to the criteria of the World Health Organization (WHO), using the indices of Decayed (D), Missing (M), Filled (F), Surfaces (S) (DMFS). In addition, Gingival Index (GI) and Plaque Index (PI) were recorded during periodontal assessment. Data was statistically analyzed by using Oneway analysis of variance, Tukey's HSD and Student's t tests.Results: Fourteen children had dental fear and 52.7% of them were not satisfied with their esthetic appearance. Although 78.2% of the children knew that brushing prevents dental caries, only 18 of them were brushing regularly twice per day. Mean DMFS, GI and PI scores were 13.18±5.68, 1.35±0.37 and 1.33±0.45, respectively. Only 20% of the children were using dental floss. There was statistically no significant difference between the DMFS scores of the children in terms of flossing. However, the difference between the mean GI and PI of the same group was found to be statistically significant (p<0.05).Conclusion: Children under state protection were found to have a reasonable knowledge of the causes of dental caries and gum bleeding. Therefore, adequate management of this positive attitude can significantly improve the oral health of this population.","PeriodicalId":30947,"journal":{"name":"Journal of Istanbul University Faculty of Dentistry","volume":"51 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2017-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/7c/05/jiufd-051-001-a.PMC5573488.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35552068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to investigate the LL-37 levels in the gingival crevicular fluid (GCF) of middle-aged and young adults who have either gingivitis or healthy periodontal tissues.Materials and methods: Forty middle-aged adults (20 healthy controls and 20 with gingivitis) and 41 younger adults (20 healthy controls and 21 with gingivitis) were included in the present study. Probing depth, clinical attachment level, plaque index, and papilla bleeding index were recorded. LL-37 levels in the GCF were analyzed by enzyme-linked immunosorbent assay.Results: No significant differences were observed in the GCF LL-37 levels between young healthy and middle-aged healthy subjects. Also, there were no significant differences in GCF LL-37 levels between young and middle-aged gingivitis subjects. However, gingivitis groups had significantly higher GCF LL-37 levels than healthy groups (p<0.001). Correlation analysis demonstrated no significant correlation between age and GCF LL-37 levels neither in healthy nor in gingivitis groups.Conclusion: The levels of LL-37 in GCF increase in the presence of gingival inflammation, however, this does not vary according to subjects being young or middle-aged.","PeriodicalId":30947,"journal":{"name":"Journal of Istanbul University Faculty of Dentistry","volume":"51 1","pages":"15-21"},"PeriodicalIF":0.0,"publicationDate":"2017-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.17096/jiufd.42354","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35449598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In half of the cavities in each group, artificial secondary caries lesions were simulated. All cavities were restored by using composite resin. All specimens were embedded in silicone and they were positioned to have approximal contacts. CBCT imaging was done and data were evaluated two times with two week interval by two observers, using a five-point confidence scale. Intra- and inter-observer agreements were calculated with Kappa statistics (κ). The area under (Az) the receiver operating characteristic (ROC) curve was used to evaluate the diagnostic accuracy.Results: Intra- (κ =0.89) and inter-observer (κ = 0.79) agreements were found to be excellent. Az values were highest for the O restorations which is followed by the MOD and DO/MO restorations. Az values for MOD and DO/MO restorations were very low and no statistically significant difference was found. Sensitivity for DO/MO restorations and specificity for MOD restorations were found to be the lowest values.Conclusion: Diagnostic performance of CBCT was higher in O composite restorations than MOD and DO/MO restorations for secondary caries detection. The use of alternative imaging methods rather than CBCT may be useful for evaluating secondary caries under composite MOD and DO/MO restorations.","PeriodicalId":30947,"journal":{"name":"Journal of Istanbul University Faculty of Dentistry","volume":"51 1","pages":"22-27"},"PeriodicalIF":0.0,"publicationDate":"2017-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.17096/jiufd.62563","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35449599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The United States Public Health Service criteria were used to assess the clinical evaluation.
