To evaluate the transverse strength of three kinds of heat cured acrylic resin, namely, Meliodent HC, Acron S, Lucitone 199; one kind of microwave acrylic resin, namely, Acron MC; one kind of visible light curing resin, namely Triad VLC; and one kind of cold cured acrylic resin, namely Meliodent CC.
Methods:
A total of 60 specimens (65mm x 10mm x 3mm) were fabricated, 10 from each material. The specimens were loaded until failure on a three-point bending test machine (AVK, Budapest). For statistical analysis, Kruskal-Wallis test followed by Dunn's multiple comparison test were used.
Results:
The transverse strength values showed statistically significant differences among acrylic denture resin groups (p=0.0001). The mean transverse strength (N/mm2) was as follows: Acron MC 124.30 ± 9.91, Meliodent HC 120.00 ± 9.13, Acron S 113.30 ± 10.88, Lucitone 199 103.40 ± 11.96, Meliodent CC 84.64 ± 12.93, Triad VLC80.22 ± 9.99.
Conclusion:
Within the limitations of this study, Acron MC showed the highest mean transverse strength value among the materials tested.
