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.

The problem in this reseach is the low learning outcomes of grade V students at SD Negeri 01 Gapura. The purpose of this study was to analyze and know the significant relationship between learning facilities and learning outcomes of class V SD Negeri 01 Gapura. The research method uses is quantitative. The population was 40 students and using saturated samples. The data collection tool using a questionnaire was tested for validity and reliability. The data analysis technique used product moment correlation formula. The results showed that there was a positive and significant relationship between learning facilities and learning outcomes of class V elementary school students 01 Gapura Kotabumi Lampung Utara.

The problem in this study is the low learning outcomes of class fifth students towards Mathematics. This study aims to determine the relationship between interest in learning and learning discipline with the Mathematics learning outcomes of class Vth Elementary School of Cluster Cut Nyak Dien, East Metro District. This type of research is ex-postfacto correlation. The study population numbered 221 students and the research sample was 69 students.. The data collection techniques used were observation, interview, questionnaire, and documentation study. The data collection instrument was a questionnaire with a Likert scale that had been tested for validity and reliability. The results showed that there was a significant relationship between interest in learning and learning discipline with the Mathematics learning outcomes of class V students, shown by a correlation coefficient of 0,7346 with strong criteria.

The purpose of this study is to explore the influence of the use of zoom meeting applications on students' math problem-solving skills in online learning in class V. The method in this study uses survey methods. The sample in this study was all VA SDN Duri Kepa 05 students as many as 30 students. Instruments to collect data used in this study are the use of zoom meeting applications and tests of students' math problem-solving skills. The results of the study obtained using a partial test (t) that showed that a significant 0.00 < 0.05. These results showed H0 was rejected and H1 accepted, meaning there was a  significant influence between the use of zoom on students' problem-solving abilities.

Learning media is a learning tool or device that can be used by teachers to assist them in conveying learning messages. This study aims to determine how the influence of learning media in creating active learning. This research was conducted using descriptive qualitative method. Data collection techniques in this study used interview and observation techniques. Based on the research that has been done, the implementation of learning at SDN Kebon Jahe, especially in class V, has used learning media that makes learning run active.

This study aims to improve learning outcomes class V students. This research is classroom action research. Based on the results of initial observations, student learning outcomes are still low. This study uses the Cooperative Integrated Reading and Composition learning model. This research was conducted at SDN 4 Bebetin in fifth grade students with a total of 15 students, consisting of 3 male students and 12 female students. Based on the results of the study, there was an increase in student learning outcomes from cycle I to cycle II. 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.

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.

Abstract 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.

<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. The population of students from class V Safa, V Marwa and V Thursina and samples taken using a purposive sampling technique that was recommended by the vice-principal and homeroom teacher totaling 42 students. Data obtained using a Likert scale that has been proven valid, and then processed using the SPSS 22.0 application. Based on the results of a simple regression test results obtained Fcount 5.621 &lt;Ftable 4.08 that H0 is accepted while Ha is rejected, meaning there is an influence between television media and social behavior of students at SD IT Syahiral Ilmi. 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>
