    Can the use of surface sealant on restorative materials prevent discoloration related to iron syrup supplements?
    (Springer, 2021) Yildirim, S.; Kaya, E.; Tıbbi Laboratuvar Teknikleri / Medical Laboratory Techniques
    Purpose The purpose of this study was to evaluate the impact of surface sealants on the stain resistance of restorative materials exposed to iron syrups. Methods Sixty specimens were prepared from each of three restorative materials-compomer (Dyract XP), a microhybrid composite (Filtek Z250), and a nanohybrid composite (G-aenial Anterior). Specimens were divided into three solution groups (n = 20) and immersed in two iron syrups (Ferrum and Ferro Sanol B) and distilled water. Two subgroups, sealed (BisCover ( +)) and unsealed (BisCover (-)), were established for each group (n = 10). Color changes between baseline and measurements at 4, 8, 24, 48, and 72 h were calculated with CIEDE2000 (Delta E-00) metrics. Data were analyzed with 4-factor mixed-design ANOVA. Results The first null hypothesis of this study that the use of surface sealant would not mitigate the restorative materials' susceptibility to staining was rejected: significant differences were found between BisCover ( +) and BisCover (-) groups in Delta E00 values for all restorative materials tested in Ferro Sanol B (p < 0.001) and Ferrum (p = 0.002) solutions. The Delta E-00 values in the Ferro Sanol B/BisCover ( +) groups were significantly lower than in Ferrum/BisCover ( +) groups (p = 0.002), the second null hypothesis that different forms of iron syrups would not impact the staining resistance of restorative materials was rejected. Delta E-00 values were different for each restorative materials tested, the third null hypothesis that the type of restorative material would not affect staining resistance was rejected. Conclusions The application of surface sealant significantly improved the color stability of restorative materials. The content of iron syrups was also an important factor affecting color change. Nanohybrid composites seem to be more resistant to the staining effects of iron syrups.

    Assessment of 5-6 Years Old Children's Perception of Environmental Awareness & Environmental Protection
    (2013) Ozyaral, O.; Karakaya, M.; Kaya, E.; Tıbbi Laboratuvar Teknikleri / Medical Laboratory Techniques
    The aim of this study was to identify and assess the perception of environmental awareness and protection among preschool children (4-5-6 years old), and develop education programs accordingly. To that end, we carried out a survey that consisted of 46 questions by means of face to face question-answer method. To create environmental consciousness and raise awareness of environmental protection at an early age, it is very important to make a proper assessment of answers given to the questions about the role of education in the creation of environmental awareness and environmental protection, when and how such education should take place, and from where such education should be received to achieve higher efficiency. In this context, the answers to the aforementioned questions will help us develop healthy methods to create environmental consciousness, raise realistic, permanent awareness of environmental protection, and instill good habits. The subjects of the study were 37 children, who were attending research-based preschool institutions resident in the districts of Ki{dotless}zi{dotless}ltoprak-Erenköy on the Anatolian Side of Istanbul. The children were at the same time attending regular preschool institutions. Within the scope of the study, we identified the parents' level of education as well as the children's perception levels about environment and environmental pollution (air pollution, water pollution, noise pollution, soil, and recycling), information sources, lifestyles, and habits. The study revealed that, along with the parents' educational background, the education received from preschool institutions and mass media play a significant, efficient role in the creation of environmental consciousness and awareness of environmental protection among children, and that we need to develop more efficient means of education. © SGEM2013 All Rights Reserved by the International Multidisciplinary Scientific GeoConference SGEM.
