Abstract

The use of acrylic denture bases in the oral cavity requires biocompatibility. This study investigated the viability of BHK-21 fibroblast cells after treatment with an acrylic denture base modified using natural fibers. Ramie and banana stem fibers were used as cost-effective alternatives to synthetic fibers. The study involved 42 acrylic resin specimens (10 mm diameter, 2 mm thickness) divided into groups: resin without fibers, 0.5%, 1.5%, and 2.5% ramie fibers, and 0.5%, 1.5%, and 2.5% banana stem fibers. The resin was incubated with cell culture media at 37°C for 7 days. Cytotoxicity testing using the MTT method revealed that all treatment groups had cell viability exceeding 70%, meeting ISO 10993-5 standards. No significant differences in cell viability were observed between the treatment groups and the control (media without specimens). Additionally, adding 0.5%, 1.5%, and 2.5% ramie fibers did not affect BHK-21 cell viability compared to the resin-only control, while adding banana stem fibers increased cell viability compared to the control (P = 0.035; P = 0.021; and P = 0.011). In conclusion, increasing the concentration of natural fibers in acrylic denture bases did not negatively impact fibroblast cell growth.

Abstract

According to the World Health Organization (WHO) conveyed in The World Oral Health Report that the level of awareness of the Indonesian population in caring for dental and oral hygiene is not good so that there are 90% of individuals who have oral health problems and an increase in the prevalence of edentulous / tooth loss reaching 24%. tooth loss that is too long, can also cause a decrease in alveolar bone in edentulous areas, decreased masticatory function to speech disorders and can also affect the temporomandibular joint. Some data mention the lack of knowledge and motivation to use dentures. The study aimed to determine the relationship between knowledge and motivation for using and maintaining dentures for health at the Melati Posbindu RW.06 gunung village. This type of research is quantitative with a cross-sectional research design. The research sample was participants of Posbindu Melati RW 06, Gunung sub-district, using a purposive sampling method that met the sample inclusion criteria, totaling 30 respondents. The inclusion criteria for this study were participants aged ≥ 15 years and willing to be respondents, with exclusion criteria for respondents with severe oral disease and mental disorders. Analyzed using the Spearman rank correlation analysis statistical test with SPSS 25. The results of the research conducted obtained the results of the Spearman Rank Correlation analysis that the results of the significance of the relationship were known to have a significance value or sig. (2-tailed) of p value 0.000 with a magnitude of the relationship between the knowledge variable and motivation of 0.881. It can be concluded that there is a very strong relationship between knowledge and motivation to use and care for dentures for health at Posbindu Melati RW 06, Pegunungan Village in 2023.

Abstract

This study aims to determine the effectiveness of game education with the help of number trees in the identification of 1st grade students of SDN 04 Muntok. This study uses a quantitative method of Quasi Experimental design experiment with pretest and posttest. The population of this study is all 1st grade students of SDN 04 Muntok, namely classes 1A and 1B totaling 40 people. The sampling technique used is purposive sampling. Based on the average posttest score obtained by the control class was 72.50 and the experimental class was 82.50. Hypothesis testing of the data of this study uses an independent sample t-test with hypothesis testing criteria, namely if the tcount > table. It was obtained with the values of tcal = 2.133 > ttable = 1.686 and sig. (2-tailed) = 0.039 < 0.05, then the calculation shows that Ha is accepted and Ho is rejected or the hypothesis states that it is proven that there is an effectiveness of games education with the help of number trees in the identification of 1st grade students of SDN 04 Muntok.
