Aim: The aim of the study was to compare and evaluate the microleakage under the Adhesive Precoated Plus (APCP), APC Flash-Free (APCF), and conventional stainless steel (SLS) brackets on the occlusal and gingival sides of the bracket base. Materials and Methods: 66 extracted premolar teeth were collected and divided equally into 3 groups. Bonding was done with APCP, APCF, and conventional SLS brackets using Transbond XT. After bonding, the samples were stored in a distilled water and thermocycled for 3000 cycles, followed by immersion in a 2% methylene blue for 24 h. After cleaning, the teeth were mounted in acrylic and sectioned longitudinally at about the center of the bracket in a buccolingual direction. Microleakage was recorded using a stereomicroscope. Results: Kruskal-Wallis H test showed a significant difference (P < .005) in the microleakage scores between the 3 groups. Mann-Whitney U test showed a significant difference between group 1 to group 2 and group 1 to group 3 (P < .005) and an insignificant difference between group 2 and group 3 on the occlusal side (P = .116) and on the gingival side (P = .063). Conclusion: Conventional SLS bracket group exhibited greater microleakage scores at both occlusal and gingival sides, when compared with APCP and APCF groups. [ABSTRACT FROM AUTHOR] |
