Objective: To identify among the composite resins, which present greater color matching with the Vita Classical scale. Method: Six groups were formed; the Tetric N-Flow® color A1 resin was used as light control and the Tetric N-Flow® A4 color as dark control and 4 A2D color resins (Oplais, Empress Direct, Esthelite and Z350). For each material, ten specimens were prepared. The reading of each test specimen was performed through a spectrophotometer and then annotated the CIELab standard, in addition to reading through the hue and chroma. A visual evaluation was performed between 4 evaluators so that they could check the resins against the light and dark patterns. Results: The tonality of each specimen presented a low percentage of correspondence, in relation to the A2 color of the Vita scale. The ΔE values of the groups and the A2 range of the Vita scale were submitted to statistical analysis with 5% significance. ANOVA resulted in statistically significant differences for all sample groups (p <0.05). The Tukey test showed no color match between the analyzed materials and the reference hue of the Vita scale. Conclusion: there was no color match with the reference A2 of the Vita scale; the differences of composition and manufacturers result in colors that are close but different. *Correspondence to: Diogo de Azevedo Miranda, Rua Sampaio 330/602, Granbery, Juiz de Fora, Minas Gerais 36010-360, Brazil, E-mail: diogoodonto@yahoo.com.br","PeriodicalId":91065,"journal":{"name":"Dental, oral, and craniofacial research","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77503927","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 relationship of smokers who smoked inside the home toward preventive care (measured as dental sealant placement) of the children living in their homes is examined in this study.Methods: Data from the National Health and Nutrition Examination Surveys in 2001-2002 and in 2011-2012 were analyzed. Data included variables to someone smoking inside the home, dental sealant placement in children ages 6-less than 20 years, and sociodemographics which were obtained from a dental examination and a home interview.Results: There were 3,352 eligible participants in 2001-2002 and 2,374 in 2011-2012. The unadjusted odds ratio for not having dental sealants when there was someone who smoked inside the home as compared with not having dental sealants when there was no one who smoked inside the home was 1.57 (95%CI: 1.17, 2.10) in 2001-2002. The unadjusted odds ratio was 1.56 (95% CI: 1.20, 2.03) in 2011-2012. When the data were adjusted for age, sex, race/ethnicity, insurance, and income to poverty ratio, the 2001-2002 adjusted odds ratio was 1.31 (95%CI: 0.97, 1.78). The adjusted odds ratio in 2011-2012 was 1.41 (95% CI:1.01, 1.95).Conclusions: Children who lived in homes in which someone smoked inside the home were more likely to not have dental sealants compared with children who lived in homes in which no one smoked inside the home. These results are important for understanding the factors related to access to dental care issues for children.","PeriodicalId":91065,"journal":{"name":"Dental, oral, and craniofacial research","volume":"1 1","pages":"3-9"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4511114/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33871535","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}
