Background:Immersion of acrylic resin plates in effervescent granules of 10% sargassum policystum as denture cleansher can inhibit the growth of Streptococcus Mutansand Candida Albicans.It is not yet known whether the resin can cause changes in compressive strength after immersion. Aims:To determinethechanges in compressive strength of acrylic resin plates after immersionin denture cleansherof 10% SargassumPolicystum. Method:This laboratory experimental study used acrylic samples with a size of 25mm × 15 mm × 2 mm totaling 18 pieces. The sample were divided into 3 groups, SodiumPerboratgroups, Sargassum policystum10% effervescentgranules groupsand aquadestgroups.Immersion is carried out atroom temperature with a immersiontime of 4.8, and 12 hours. Compressive strength is measured using Universal Testing Mechine after immersion. The statistical tests used are the ANOVATest and the LSD Test. Results:There was a decrease in the strength of the acrylic resin plate after being immersed in denture cleanshercleansher of 10% SargassumPolicystum, but it was not statistically significant.Conclusion: Immersion of acrylic resin plate in denture cleansher of 10% SargassumPolicystumdoes not reduce compressive strength of acrylic resin plates.
