    Can energy drinks affect the surface quality of bioactive restorative materials?
    (Bmc, 2024) Kose, Hazal Deniz; Giray, Ilayda; Boyacioglu, Hayal; Turkun, Lezize Sebnem
    Backgrounds: This study aimed to compare the effects of different energy drinks on the surface roughness, weight loss, and color change of various bioactive restorative materials. Methods: Charisma Diamond One, Activa (TM) BioActive Restorative, Activa (TM) Presto (TM) and Equia Forte HT Fil samples were prepared using plastic molds (8 x 2 mm) (n = 10/groups). After polishing, the samples were weighed, their colors were recorded using a spectrophotometer according to the CIEDE2000 system, and their surface roughness was measured using a profilometer. The samples were immersed in Powerade, Burn, Monster and distilled water for 7 days. After immersion, all the measurements were repeated. Statistical analyses were performed using the Wilcoxon signed-rank test and the Mann-Whitney U test (p < 0.05). Results: All energy drinks roughened the surface of Equia Forte HT Fil (p < 0.05). Powerade and Monster increased the Ra of all materials after 7 days (p < 0.05). Burns affected all materials except the Activa Bioactive (p < 0.05). Significant weight loss was observed in the Equia Forte group after immersion in all the energy drinks, whereas no weight loss was observed in the other groups. According to the color measurements, Delta E-00 values were greater in the Burn and Monster groups, except for the Equia Forte HT Fil group (p < 0.05). Conclusion: Energy drinks affected bioactive materials to varying degrees. The glass hybrid material was the most affected, and the bioactive restorative materials based on the resin matrix were the least.

    Evaluating the Effect of Different Mouthrinses on Properties of the Enamel and Dental Composite Surfaces
    (Revista Chimie Srl, 2024) Kose, Hazal Deniz; Seker, Oya
    This study investigated the effects of different solutions (artificial saliva, Listerine Cool Mintalcohol containing and Colgate Plax-alcohol free) on the nanohardness, elastic modulus and surface roughness of enamel surface and composite materials (Admira Fusion, Clearfil Majesty Esthetic and Mosaic Universal). Specimens of 2 mm depth and 5 mm diameter were stored in solutions for 12 h at 37(degrees)C. Baseline and final measurements were obtained using a HYSITRON TI 950 TriboIndenter testing machine. The applied force to each specimen increased from 0 to 1000 mu N. For SEM images, one sample in each group was covered with a thin layer of mix of gold and palladium using a sputter coater (Quorum Q150R ES, UK). Scanning electron microscopy (SEM) images were taken at 5000x magnifications to evaluate the surface morphology. Statistical analysis for hardness, elastic modulus and roughness was performed by Two-way ANOVA, Benferroni and Tukey HSD at a significance level 0.05. The results of this study showed that the highest value of surface roughness and lowest hardness and elastic modulus were presented by Admira (p<0.001). Listerine caused significantly increased surface roughness (p<0.001) and decreased hardness and elastic modulus parameters (p<0.001). The mouthrinse containing alcohol caused more significant changes in the nanohardness, elastic modulus, surface roughness values of enamel and composite surfaces.

    Oral and Dental Health Knowledge and Attitudes among Parents of Children
    (Marmara Univ, Inst Health Sciences, 2023) Kose, Hazal Deniz; Sen Yavuz, Betul; Kargul, Betul
    Objective: This study aims to evaluate parents' knowledge and attitudes level on oral and dental health. Methods: One hundred and thirty parents of children aged 6-12 years, were invited to participate in the study. A 33-item questionnaire covering socio-demographic characteristics, dental attitude, dietary practices, tooth eruption, dental caries, and oral hygiene practices, was distributed to parents. The relationship between categorical variables was tested with the Chi-square test. Results: The sample comprised of 100 parents with a mean age of 37.1 +/- 6.4. The knowledge and attitudes towards dental caries and oral health habits among parents did not differ significantly according to the parents' gender, education level, or dental chair experience. There was a statistically significant difference in the responses of the first primary tooth and the first exfoliating primary tooth according to the gender of the parents (p=0.031, p=0.002, respectively). Although the education level of the parents did not affect the answers about the number of primary and permanent teeth, a statistically significant difference was found in the time of first primary tooth eruption (p=0.008). Conclusion: The study showed that parents do not have enough knowledge and awareness of dental caries and oral healthcare. Oral healthcare should be promoted as a part of general health and the awareness of the public should be increased.
