[Penelitian ini bertujuan untuk mengetahui pengaruh perendaman dalam obat
kumur tanpa dan mengandung alkohol terhadap transverse strength resin akrilik
polimerisasi panas. Spesimen berupa lempeng direndam di dalam obat kumur
mengandung alkohol, tanpa alkohol, atau akuades selama 12, 24, dan 36 jam.
Transverse strength diperoleh dengan menggunakan metode three point bending.
Uji statistik menyatakan tidak ada perbedaan transverse strength yang bermakna
antara spesimen yang direndam di dalam larutan perendam untuk setiap waktu
perendaman maupun antar waktu untuk setiap larutan perendam. Penggunaan obat
kumur tanpa dan mengandung alkohol tidak menurunkan transverse strength
basis gigi tiruan resin akrilik polimerisasi panas., The aim of this study was to know the effect of immersion in alcoholic and non
alcoholic mouthwash on transverse strength of heat cured acrylic resin. Specimen
plates were immersed in alcoholic mouthwash, non alcoholic mouthwash or
aquadest for 12, 24, and 36 hours. Transverse strength was measured using
universal testing machine. Result showed that there was no statistically difference
among the transverse strength of specimens either between immersion solution
for each immersion time or between immersion time for each solution. The use of
either alcoholic or non alcoholic mouthwash will not decrease the transverse
strength of heat cured acrylic resin denture base.]
