| dc.description.abstract | Enamel decalcification around and under the bracket base is a considerable problem. Microleakage under the orthodontic brackets increases the risk of decalcification and caries. There is a lack of information about microleakage that may occur under the orthodontic bracket when different types of adhesive are used and how it is affected by acidic soft drinks. The purpose of this study was to compare the degree of microleakage between the conventional orthodontic bonding system and integrated orthodontic bonding system and the effect of acidic soft drinks on microleakage at the cervical and occlusal region. A total of 80 sound upper permanent premolar teeth were used. Obvious tissue remnants on the roots were removed and the buccal surfaces were polished. The teeth were randomly divided into four equal groups. Group 1 and Group 3 were bonded with conventional bonding system (Two-step etching primer + Adhesive + Metal bracket). Group 2 and Group 4 were bonded with integrated bonding system (Self-etching primer + Adhesive pre-coated bracket). The teeth of all groups were stored in distilled water for 4 weeks. After that, teeth of group 3 and 4 were further stored in acidic soft drink (Coca-Cola® drink) for 24 hours. The apices of the teeth were then sealed with sticky wax and painted with nail varnish except for 1-mm around the bracket and then placed in 0.5% Rhodamine B dye. After 24 hours, teeth were washed and mounted in clear acrylic resin blocks. Each tooth was then cut longitudinally in the buccolingual direction producing three examinable surfaces. Each surface was examined for microleakage under confocal laser scanning microscope. Microleakage in the enamel-adhesive interface and the adhesive-bracket interface were then measured under the digital calibrated image analyzer. Data was analyzed by using SPSS software and independent t-test was used for comparison. P < 0.05 is considered statistically significant. | en_US |
