Effects Of 25%, 37.5% and 50% Musa Acuminata Extract as a Denture Cleanser on the Flexural Strength and Surface Roughness of Acrylic Resin

Abstract

Mauli banana (Musa acuminata) stem extract contains potential bioactive compounds against Streptococcus mutans and Candida albicans in which can be used as an alternative for synthetic denture cleanser. The use of denture cleanser may weaken flexural strength and surface roughness of heat-cured acrylic resin. This study was subjected to analyse the effect of 25%, 37.5% and 50% Mauli bananas stem extract immersion as a denture cleanser to surface roughness and flexural strength of heat-cured acrylic resin. Seventy specimens of heat-cured acrylic resin were fabricated in rectangular shape with 65 mm × 10mm × 3.3 mm in size according to ISO standard 1567. Treatment groups comprised of Mauli banana stem extract at the concentration of 25%, 37.5%, 50% while 0.2% Chlorhexidine gluconate (CHX) and aquadest were used as control groups. Heat-cured acrylic resin immersion was performed for 5 days. Thirty-five specimens were tested for flexural strength using universal testing machine and other 35 specimens were tested for surface roughness using surface roughness tester SJ-30. Analyzing results with one-way ANOVA test, no significant differences (p=0.986) of surface roughness was obtained from Mauli banana extract of 25% (0.158±0.020 μm), 37.5% (0.160±0.030 μm) and 50% (0.162±0.037 μm), 0.2% CHX (0.155±0.020 μm), aquadest (0.157±0.022 μm). The result flexural strength was significantly differed between 0.2% CHX (79.05±3.10MPa) and aquadest (94.36±6.31MPa) (p=0.003) with no significant differences (p>0.05) between Mauli banana stem extract concentration group 25% (85.30±8.65MPa), 37.5% (84.91±6.60MPa) and 50% (83.60±8.36MPa). No effects of 25%, 37.5% and 50% mauli banana stem extract immersion was presented upon flexural strength and surface roughness of heat-cured acrylic resin therefore it can be used as an alternative for denture cleanser material.
