| Abstract | ||||
| Tooth bleaching is one of the modern cosmetic approaches in dentistry. The aim of this study was to evaluate the effect of ethanol-based adhesive (ExciTE®, Ivoclar Vivadent, Liechtenstein, Germany) application on the shear bond strength of orthodontic brackets bonded immediately to the teeth after vital bleaching. The study was carried out on 45 human premolars. The teeth were randomly divided into 3 groups, group 1(control group), group 2 (bleach only) and group three (bleach & Excite®). All the brackets were bonded with Transbond XT light cured composite (Unitek 3M, Monrovia, Calif). Universal testing machine was used to measure the immediate shear bond strength. Results of this study showed that, the mean values of the shear bond strengths were 12.1 Mpa, 3.9 Mpa and 11.6 Mpa for groups 1, 2 and 3 respectively. There was a significant difference between the three tested groups (p<0.05). There was a significant difference between group 1 and 2, also between group 2 and group 3 (p<0.05). On the other hand, there was no significant difference between group 1 and 3 (p>0.05). It was concluded that application of ethanol- based adhesive (ExciTE®) after bleaching could enhance the immediate bond strength of orthodontic brackets bonded to enamel surface. | ||||
