The combination of bay leaves and betel leaves infusion has been used as a toothbrush disinfectant. The purpose of this study was to obtain a stable and effective mouthwash formulation from the combination of both infusions to prevent and relieve gingivitis. Methods: Five mouthwash formulas were made by mixing the active ingredients which is a combination of bay leaves and betel leaves infusion, with additives. The combination namely F-I (100% : 0%); F-II (75% : 25%); F-III (50% : 50%); F-IV (25% : 75%) and F-V (0%: 100%). Antibacterial activity tests against Streptococcus mutans, Streptococcus sanguis, and Porphyromonas gingivalis and physical stability tests were carried out. Stability test was carried out by storing the formula at room temperature (280C), hot temperature (400C) and cold temperature (40C) for 3 storage cycles (6 weeks) and observing changes in the physical indicators of the solution, namely pH, specific gravity, viscosity and organoleptic conditions, namely homogeneity, clarity, color, aroma and taste at the end of every 2nd week. Results: F-I to F-V had no inhibitory activity against Streptococcus mutans and Streptococcus sanguis, but had inhibitory activity against Porphyromonas gingivalis in the range (7.19±0.48) to (8.29 ±0.82) mm (ANOVA with a significance value of 0.237 > 0.05).  The 5 formulas were more stable at cold storage, with organoleptic observations at the end of the 3rd cycle showing a slight precipitate (+), clear solution, light brown color, mint aroma and sweet taste. F-II formulas showed better physical indicators values because they were closer to the standard values. Conclusion:  The F-II formula is recommended as a mouthwash for gingivitis because significant for antibacterial effect and showed better physical indicators values as the standard values for herbal medicines.Keywords: antibacterial activity; bay leaves - betel leaves infusion; gingivitis; mouthwash formulation.","PeriodicalId":31757,"journal":{"name":"Padjadjaran Journal of Dentistry","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41910355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

APF gel is believed to be effective in reducing the demineralization effect of the teeth as well as escalating the remineralization process. This research aims to determine and evaluate the effectiveness of 1.23% APF gel as a preventive agent for the erosion of tooth enamel, specifically in deciduous teeth. Methods: This type of research is true experimental research. The population of this research would be primary teeth extracted from children, using a purposive sampling technique with inclusive and exclusive criteria. A total amount of 5 maxillary primary central incisors were extracted and cleaned. APF gel was applied repetitively on the left side of the teeth for 4 minutes every hour, whereas the right side was left as it is. Samples were then analyzed using a scanning electron microscope (SEM). A qualitative and subjective analysis regarding the micromorphological features of the erosion can be done. Result: The side of teeth without APF gel application has a greater erosion rate compared with teeth with APF gel application. The tooth which is demineralized shows a honeycomb structure of the interprismatic enamel. As for the dentinal tubules, teeth without APF gel application have a bigger opening of dentinal tubules, going up to 7.868 micrometers in size compared to teeth with APF gel application (1-2 micrometers).

Lip wound healing is a critical need for aesthetic performance. The purpose of this study is to evaluate the efficacy of natural lip balm C. Burmannii has been shown to speed up the healing of incision wounds in rats (Rattus norvegicus). Methods: This research was carried out in the laboratory biomedical Faculty of Medicine, Universitas Islam Bandung. In twenty-seven male rats weighing 200-300 g, a lip mucous incision of 10 mm length and 4 mm depth was surgically created. Simple random sampling was used to divide the animals into three treatment groups based on wound treatment after lip incision (The control group applied distillation water, the first group applied a lip balm placebo/base, and the second group applied natural lip balm C. burmannii) and then divided into three observation times (days 3rd, 7th, and14th). A lip biopsy was performed during each observation time to determine the success of the therapy. The macroscopic examination was carried out by counting the number of lip wounds that were closed around, while the microscopic examination was carried out by counting epithelialization with a Leica microscope and image raster software. Result: The length of the lip wound has greatly decreased in the C. Burmannii group with a p-value of 0,048 (p<0.05, and epithelialization was comparable across the board.

Dental fillers must be smaller to improve their mechanical, physical, and biological properties. Material processing and centrifugation contribute to the size of processed materials. This study evaluates the effect of different centrifugation speeds on the size and distribution of glutinous rice flour as organic dental filler. Methods: This experimental study uses glutinous rice flour suspended in water and then centrifuged at different speeds of 3000 and 6000 rpm compared to untreated glutinous rice flour as control. The particle size was examined using Scanning Electron Microscope (SEM) and Dynamic Light Scattering (DLS). Next, Fourier Transform Infra Spectroscopy (FTIR) and X-ray Diffraction (XRD) were performed to evaluate whether there were structure and crystallinity changes. Finally, the cytocompatibility of fillers was examined by a cell viability test. Results: Centrifugation of glutinous rice flour at 3000 rpm resulted in smaller average size particles, evenly distributed, and higher crystallinity than other groups. There were no changes in functional groups, as shown by FTIR spectra. However, the processed samples were more amorphous compared to the control. Importantly, the processed samples appeared to be non-toxic, with a range of cell viability of 82.75-86.67% after 24 h incubation. Conclusion: Centrifugation speed of 3000 rpm has decreased in size, and a more homogenous particle size of organic filler made from glutinous rice flour. Importantly, it improved the cytocompatibility of particles compared to untreated control.
