Nanohybrid composite resin is a material of choice for restoration of both anterior and posterior teeth. One of its mechanical properties that plays important role to withstand mastication force is compressive strength. Due to a high demand of aesthetic restorations, the importance of contamination control requires special concern since composites are sensitive to contamination. The aim of this study was to determine the effect of glove, blood, and saliva contamination on the compressive strength of nanohybrid composite resin. Twenty-four specimens were randomly divided into four groups based on the type of contamination. The mean and standard deviation values (MPa) for compressive strength were as follows: Group 1= 151.57±17.97, Group 2= 159.94±18.55, Group 3= 134.91±25.53, Group 4= 151.72±17.34. All groups did not show a statistically significant difference (p>0.05) in compressive strength. In conclusion, glove, blood, and saliva contamination do not affect the compressive strength of nanohybrid composite resin.
