dc.description.abstract | Objectives: The aim of the present study was to evaluate the effects of 1.5T and 3T MRI on
the adhesion between the orthodontic brackets and the teeth by evaluating the microleakage
between the enamel, adhesive and brackets interfaces.
Methods: 58 extracted human premolars which were received a standard bracket bonding
procedure were randomly divided into three groups; control group (n = 20; no MRI), 1.5T
MRI group (n = 19; 20min MRI exposure of 1.5T) and 3T MRI group (n = 19; 20min MRI
exposure of 3T). The teeth were kept in distiled water for 2 weeks, and thereafter subjected
to 500 thermal cycles. Then, specimens were sealed with nail varnish, stained with 0.5% basic
fuchsin for 24h, sectioned and photographed under a stereomicroscope. Microleakage was
scored with regard to the adhesive–enamel and bracket–adhesive interfaces at the occlusal and
gingival levels. Statistical analysis was accomplished by Kruskal–Wallis and Bonferroni–Dunn
tests.
Results: All of the groups exhibited statistically similar microleakage scores in the adhesive–
enamel interface along occlusal margins (p>0.05, p = 0.331). The mean microleakage scores
along gingival margins in the 3T MRI group was significantly higher compared to the control
group both in the adhesive–enamel and bracket–adhesive interfaces (p<0.05, p = 0.019 and p =
0.020 respectively). The microleakage scores along the gingival margins were also significantly
higher than the occlusal margins in the 3T MRI group (p<0.05, p = 0.029).
Conclusions: 3T MRI may weaken the adhesion between the enamel and the stainless steel
