| Abstract | ||||
| The purpose of this current study was to evaluate the effect of acidic soft drink (Cola type) on etched and sealed enamel and bond strength of conventional chemical cure and fluoride releasing light cure orthodontic resins. Twenty extracted premolars were collected and part of the buccal surfaces were etched and then divided into two groups. The first group (n=10) was sealed with chemical cure and the second group (n=10) was sealed with fluoride releasing light cure resin and buttons were bonded. The teeth were prepared and exposed to cola, the sample was tested to evaluate the difference of shear bond strength of both groups, then the samples were examined under electron microscope scanning. The results indicated that enamel defect zones were observed in both groups, but the fluoride releasing groups was less than that of the chemical cure resin. Shear bond strength was significantly high in fluoride releasing group than that of the conventional chemical cure resin. | ||||
