Abstract

Composite resin is a sensitive material that needs a dry and clean operative area. This study aimed to determine the effects of saliva and blood contamination after bonding on shear bond strength of composite resin to enamel. It also compared several cleansing methods. Twenty-five samples of human premolars, mounted in acrylic blocks, were divided randomly into five groups (n = 5) based on type of contamination and cleansing procedures. The greatest shear bond strength was seen in the control group (14.78±0.89) while the blood-alcohol group showed the lowest bond strength (9.02±1.10). Contamination groups cleaned by water rinsing had greater shear bond strength than groups cleaned by alcohol swabbing. Significant differences (p < 0.05) were seen between the control group and the contamination groups. In summary, contamination of saliva and blood after bonding decreased the shear bond strength of composite resin to enamel. Water rinsing is more effective than alcohol swabbing in restoring bond strength.
