Objective: To determine the effectiveness effectivity of mouthwash from Aloe vera juice after scaling treatment on patient with gingivitis. Material and Methods: This was an experimental research using pretest and posttest design with control group. The number of samples of 30 people selected using sampling method quota sampling. Samples were divided into two groups: test (n = 15 skeletons with Aloe vera juice) and control (n = 15 just scaling). Gingival inflammation is measured using a gingival index according to Loe and Sillness on the first day before scaling treatment and 7th day after scaling. Data analysis was conducted using SPSS version 20. Independent-samples t-test and paired-samples t-test were used for data analysis. The statistical test performed has a significance level of 0.05 (p = 0.05) and confidence level of 95% (α = 0,05). Results: There was a significant decrease in the mean score of the gingival index in the control group (1.1 to 0.5) and the test group (1.2 to 0.4) significantly (p<0.05). Conclusion: The use of mouthwash from Aloe vera juice can decrease gingival inflammation, which can be seen from the gingival index score on all test subjects. The decrease in gingival index in the test group using the Aloe vera juice was greater than that of the control group, which was not given the mouthwash.

Banana peels are generally considered to be waste usually thrown away, but in fact it has important benefits to clear water. The purpose of this study is to use banana peels to clear dirty water from rivers. The process used is filtered coated water using gravel sand, charcoal, palm fiber and the final filter layer is banana peels that acts as a place to disinfect raw water against germs and bacteria still present in the water. The results obtained indicate that water purification using banana peels meets the criteria for physical testing, including water levels with a pH between 7.0 8.5, and does not interfere with the taste and smell of water. Rainwater and river water can be used as cleaning water because the pH meets all requirements but cannot be used as clean water because bacteriologically all samples do not meet the drinking water

The aim of this literature review was to study the underlying mechanisms of the association between periodontal disease and prostate cancer. Methods: This study was literature review study, pubmed searching was used to find scientific article about association of periodontal disease and prostate cancer. Results: Direct correlation between periodontal disease and prostrate cancer is still unclear. It was hyphotesized that microorganisms involved in chronic periodontitis may directly induce mutations in the tumor-suppresor genes and proto-oncogenes or alter the signalling pathways that in turn stimulates cancer growth. Conclusion: Periodontal disease may associate to prostate cancer by mutation induction in tumor-suppresor genes.
