EVALUATING THE EFFECT OF GLOVE COATING ON THE SHEAR BOND STRENGTH OF PORCELAIN LAMINATE VENEERS

Gloves have become a standard tool in dentistry due to infection contr ol concerns. But the starch powder with which many of these gloves are coated may contaminate surfaces on contact, creating potential proble ms during adhesive procedures such as the placement of porcelain venee rs. The authors studied the powder's effect on the strength of the she ar bond of etched porcelain to etched human tooth enamel and compared it to the effect of a powder-free polymer glove coating. While the sta rch coating led to a statistically significant decrease in shear bond strength, the powder-free coating produced no significant decrease in strength.
