Effects of Rinsing Water Temperature and Preheated Composites on Microleakage of Composite Restorations with Two Bonding Agents

Objectives: The aim of this study was to evaluate the effects of rinsing water temperature and preheated composites on microleakage of class V restorations with two different bonding agents. Materials and Methods: Eighty class V cavities were prepared in the buccal and lingual surfaces of 40 molars. Single Bond and Prime and Bond NT bonding agents were used. The teeth were divided into four groups of 10. G1: After acid etching, cavities were rinsed with 23˚C water and filled with 23˚C composite resin. G2: Rinsing water and composite resin had 55˚C temperature. G3: Rinsing water had 55˚C and composite resin had 23˚C temperature. G4: Rinsing water had 23˚C and composite resin had 55˚C temperature. The specimens were immersed in 0.5% basic fuchsine dye. Microleakage scores were analysed with the Kruskal-Wallis, Mann-Whitney U, and Wilcoxon tests. Results: There were significant differences in microleakage of specimens prepared with Single Bond and Prime and Bond NT only in group 1 (P<0.05). There were no significant differences between the microleakage of groups rinsed with different water temperatures (P>0.05). There were significant differences between the unheated and preheated composite groups (P<0.05). Conclusion: Preheating of composite is a valuable method to increase its adaptability and decrease microleakage of composite restorations.

This is evidenced in the first cycle obtained 6 students (40%) who have completed and 9 students (60%) have not completed with an average value of 67. Cycle II increased to 12 students (87%) completed and 3 students (13%) incomplete with an average score of 89. From the results of cycle I and cycle II, it can be concluded that the application of the CIRC learning model can improve learning outcomes fifth grade students at SDN 4 Bebetin, Buleleng Regency.

PEMBELAJARAN DARING MUATAN PEMBELAJARAN IPS PADA KELAS V SD

This study aims to know the implementation of online learning process in social studies for fifth grade elementary school students at SDN Pondok Kelapa 06 Pagi Jakarta, as well as to know the role of learning components in online learning of social studies subject. The subjects in this study were teachers and students of class V B SDN Pondok Kelapa 06 Pagi Jakarta in 2021/2022 academic year. This research is a qualitative with descriptive method. The data collection instruments used are observation, interviews, and documentation. The results showed that the use of What’sApp as a medium in delivering learning makes it easier for teacher. However, the teacher cannot monitor the activities carried out while students are studying and doing exercises, so teacher cannot ensure that students understand the material of social studies subject optimally.

One-year Clinical Results of Restorations Using a Novel Self-adhesive Composite Hybrid

This prospective study assessed the dual-curing self-adhesive composite hybrid Surefil one. The restorations were placed and reviewed by dental practitioners who are members of a practice-based research network in the United States. Seven practitioners filled 60 cavities (20 class I, 19 class II and 21 class V) in 41 patients with Surefil one without adhesive, according to the manufacturer’s instructions. The restorations were evaluated using modified rating criteria at baseline and after 3 months and 1 year. Patients were also contacted to report postoperative hypersensitivity 1 to 4 weeks after placement. Recall rates were 98% after 3 months and 82% after 1 year. The only patient that showed moderate hypersensitvity after 1 year had previously reported symptoms that were unlikely associated to the class I molar restoration. One class II restoration in a broken maxillary molar was partially lost. The remaining 48 restorations were found to be in clinically acceptable condition resulting in an annual failure rate of 2%. The lowest number of acceptable scores (88%) was for color match. Self-adhesive composite hybrid restorations showed promising results in stress-bearing class I and II as well as non-retentive class V cavities at 1-year recall.

Pengaruh Media Televisi Terhadap Perilaku Sosial Siswa di SD Islam Terpadu Syahiral Ilmi

<p><em>This research is motivated by social behavior caused by one of them is television. This research is a quantitative approach that is correlational. By using a simple linear regression method.

From the results of the regression equation, interpretation is obtained, meaning that if the television media is 0 or normal, then the positive social behavior of students is 169,600. Interpersonal communication variable regression interpretation of -635 means that if the television media has increased, the social behavior of students is -635. The magnitude of the influence of television media with social behavior of 12.3% and 88.7% is influenced by other factors.</em></p>
