Abstract

Surface enamel damage was evaluated after debonding ceramic brackets on forty-four bicuspid teeth. These teeth had been previously bonded with two different types of ceramic brackets. One of the brackets utilized a mechanical base for retention and the other bracket utilized a polycarbonate base for retention. The brackets were bonded to the respective teeth for a total of seven to ten days. After debonding, the teeth were extracted and evaluated with a scanning electron microscope. A metal bracket SEM scan was used for a control. The study concluded that: 1) all brackets alter the surface enamel, 2) metal brackets cause the least amount of surface enamel damage, 3) statistically there was a significant difference in surface enamel damage between the metal bracket and the ceramic brackets (p = .0046), 4) there was not a significant difference in surface enamel damage between ceramic brackets having a mechanical base or a polycarbonate base.
