Evaluation of the effect of sodium hypochlorite on the transverse strength of acrylic denture base resin

Abstract

This study evaluated the transverse strength of polymerized acrylic resin after
immersion in sodium hypochlorite (NaOCl) for 20 minute, 3times a day for 15 days.
40 rectangular specimens were prepared from heat polymerized acrylic resin; 20
specimens were immersed in 0.5℅ NaOCl as experimental group and 20 specimens
were immersed in distilled water as control group. The transverse strength was
measured using a 3 –point bending test in a universal testing machine. The study
showed that there was no statistically significant differences (p>0.05) between groups.
It may be concluded that immersion in NaOCl solution did not influence the
transverse strength of heat polymerized acrylic resin.
