radiopaque

Offering major resistance to the passage of X-rays. Radiopaque substances, such as barium sulphate and iodine-containing liquids, are commonly used to outline hollow structures, especially in the intestinal canal and the urinary system. See also BARIUM MEAL and intravenous or retrograde UROGRAPHY.

The aims and objectives of this study were to: Determine the efficiency of the new indigenously developed product, Chitra polyurethane based radio-opaque light cured adhesive as an orthodontic bonding adhesive and to compare the bond strength with conventional composite (Exactobond, no-mix), and to study the nature of the bond failure using the Adhesive Remnant Index (ARI) for both.
