The movement of teeth during processing of complete dentures disturbs the harmonious occlusal scheme established at the final wax try-in stage. Aims and objectives: to investigate the effect of RS flask closure on occlusal vertical dimensions of complete dentures. The mean occlusal vertical dimension of complete maxillary and mandibular dentures fabricated by the conventional flask closure were measured and compared with that of dentures fabricated by RS flask closure. Design: A pre-test post-test control group experimental design. Methods: Thirty sets of complete maxillary and mandibular wax trial dentures were randomly assigned to experimental groups. Fifteen sets were assigned to conventional flask closure and the remainder to RS flask closure. Compression molding with a long curing cycle was performed for the processing of the dentures. Pre-processing and post-processing occlusal vertical dimensions were determined. Results: The mean occlusal vertical dimensions of wax trial dentures assigned to either group were similar. The data produced substantial evidence to reject the null hypothesis that the post-processing mean occlusal vertical dimensions of both groups were equal. Conclusion: The occlusal vertical dimensions produced by dentures clamped by the RS flask closure were significantly less than those produced by dentures clamped by the conventional flask closure.

One technique that can be applied to increase assertiveness is assertiveness training. This study aims to determine the effect of assertive training techniques to increase assertiveness on sexual behavior in dating by using a pre-experimental approach with pre-test and post-test Control Group Design as well as non-probability sampling techniques and then analyzed by bivariate and multivariate analysis. The results of the independent sample t test for the level of assertiveness showed that the value of p = 0.001 with a test value of t = 7.394, which means that there is an effect of assertive technique training on the assertiveness level of adolescents in sexual behavior. The mean value in the provision of assertive technique training is known to be 4.09 and the mean value to the control is 0.36, this means that there is a change in the value of the assertiveness level of assertiveness towards sexual behavior in dating.

This study investigated the effect of different microwave curing cycles on the changes in occlusal vertical dimension of complete dentures. Four test groups with 12 maxillary dentures each were evaluated. Groups 1, 2 and 3 were polymerized with different cycles by microwave radiation and Group 4 was the control and cured by water bath. The average pin opening for all groups was less than 0.5 mm. There was no significant difference between the groups polymerized by the microwave method and the control group. However, analyses of the vertical dimension changes showed statistically significant differences between groups 2 (0.276 ± 0.141 mm) and 3 (0.496 ± 0.220 mm).

Green tea has a lot of cathecin which has role as antihyperglycemia and antioxidant to prevent diabetes complication. The aim of this research is to determine the effect of green tea on blood glucose level and serum MDA level in alloxan-induced mice. This research was a true experiment with randomized post-test control group design. The sample consisted of 35 mice divided into five groups, negative control (K-), positive control (K+), treatment 1 (P1), treatment 2 (P2), and treatment 3 (P3). The K- group was the normal group, given standard diet only, the K+ group was induced alloxan only, the P1, P2, and P3 groups were induced alloxan and given 1%, 2%, and 4% green tea infusion for 15 days. The mean of blood glucose level on K-, K+, P1, P2, and P3 group were 73,14 mg/dl, 210 mg/dl, 164,57 mg/dl, 152,57 mg/dl, and 135,83 mg/dl.

Objective: The definitive treatment of preeclampsia until the fetus and placenta are delivered with magnesium sulfate (MgSO4) is a modality for the prevention and treatment of eclampsia. This study aims to determine the differences in serum magnesium (Mg) levels between before and after administration of MgSO4 in preeclampsia patients. Methods: This research was an analytical study with experimental design with one group pre and post-test control group design in 4 hospitals in Medan City, North Sumatera, Indonesia from July to November 2019, the preeclampsia group and as a control group is the normal pregnant women. Statistical analysis was performed to determine differences in initial serum Mg levels in the two groups, and differences in serum Mg levels before and after administration of MgSO4 in the preeclampsia group. Results: The study was conducted on 50 samples, divided into 2 groups with a total of 25 samples each. The mean Mg of serum in the preeclampsia group was 1,39 mEq/l (SD±0,28) lower than the control group, which was 1,53 mEq/l (SD±0,17) (p = 0.004). The average Mg level in preeclampsia patients before administration of MgSO4 was 1,39 mEq/l (SD±0,28), after MgSO4 administration, the average Mg level became 4,90 mEq/l (SD±0,37) (p<0,001). Conclusion: MgSO4 administration provides a significant increase in serum Mg levels in preeclampsia women. Serum Mg levels in preeclampsia patients are significantly lower than in women with normal pregnancies.

ABSTRACT Aim Occlusal errors during acryl processing affect the retention and stability of complete dentures. The aim of the present study was to assess the influence of a short curing technique on the number of occlusal contacts and the occlusal vertical dimension (OVD) of complete dentures. Materials and methods Complete dentures were prepared. The number of occlusal contacts was recorded in centric relation (CR) using 60 ì articulation paper. The OVD was recorded with the waxed trial denture in place. Dentures were then invested and processed with compression molding and short cure water bath technique. The number of occlusal contacts was recorded again. The amount of pin opening was measured for all of the complete dentures on the articulator. Data were analyzed with paired t-test to determine the alterations. Results The mean number of occlusal contacts before and after processing was 10.9 ± 2.4 and 6.3 ± 3.1 respectively (4.7 ± 1.9 decrease; p < 0.001). A 2 mm mean increase in OVD was observed in 47.7% of the dentures with < 6 occlusal contact changes and 88.9% of the dentures with > 6 occlusal contact changes (p < 0.003). A significant change in the number of occlusal contacts was associated with an OVD increased up to two times. Conclusion The short curing technique seems to be related to the decreased occlusal contacts and increased OVD. Clinical significances More time is needed to adjust the occlusal errors of this method, because it has a negative effect on the morphologic pattern of artificial teeth of complete dentures and thus should be used carefully.

Post-test only control group design was the design used in this experimental study. The post-test only control group design was designed to discover the purpose of this study which was to investigate the significant effect on writing ability between students who obtain feedback from anonymous peer assessment and students who obtain feedback from conventional assessment. The study was conducted at SMK PGRI 1 Singaraja. The eleventh grade students in Academic Year 2017/2018 were chosen as the population. The samples were 44 students from XI AP and XI UPW. The instruments used in this study were lesson plan, anonymous peer checklist, writing scoring rubric, and writing test. Writing scoring rubric and writing test were used to obtain the data through post-test while lesson plan and anonymous peer assessment were used during the treatment. The data then was analyzed by using SPSS 16. The results of the analysis show that (1) the mean score of the experimental group was 77.55 while the mean score of the control group was 68.77. (2) The t-observe was 3.892 and it exceeded the t-critical value which was 2.018. Therefore, based on the aforementioned results, it can be concluded that there was a significant difference on writing ability between the eleventh grade students who obtained feedback from anonymous peer assessment and those who obtained feedback from conventional assessment at SMK PGRI 1 Singaraja in academic year 2017/2018.
