- Abstract
Objective: The aim of the study was to compare the flexural strength of conventional resin acrylic denture with flexural strength of labelled resin acrylic denture fabricated using two different techniques; heat cured and cold cured. Materials and Methods: Forty-five resin acrylic blocks were fabricated with fixed dimensions 64 mm x 10 mm x 2.5 mm. There were equally divided into three groups; conventional (no labelling included), and heat and cold cured labelled resin acrylic. The flexural strength of each block was measured using INSTRON 8874 Universal Testing Machine (INSTRON Inc, USA). One-way ANOVA and Tukey Post-Hock Test, and one sample t-test (test value=55N) were used for statistical analyses. The significance level was set at 5%. Results: The flexural strength can be arranged in descending order of cold-cured>conventional>heat-cured techniques. All multiple comparisons were significant, p<0.05. The peak load for conventional and cold-cured labelled resin acrylic was significantly better than minimum peak load 55N (both p<0.001) while heat-cured peak load was equal to minimum peak load. Conclusion: Both techniques are acceptable for application with cold-cured labelling technique is more recommended since its flexural strength is even better than conventional resin acrylic.
