Background: Orthodontic treatment is associated with many problems that may cause complications during the therapy. These are: enamel discoloration, erosion, enamel demineralization and dental caries, especially around the orthodontic brackets. The presence of microleakage in adhesive materials used for bonding orthodontic brackets was confirmed. Microorganisms, molecules, and liquids could penetrate through the microleakage to the dental enamel and cause its damage. The aim of this in vitro study was to diagnose and evaluate the development of microleakage in four adhesive systems used in orthodontics for bonding brackets. Materials and Methods: Eighty extracted premolars were divided into 4 groups of 20 teeth. Stainless steel Legend medium metal brackets were bonded to teeth with GC resin reinforced glass ionomer cement GC Fuji Ortho LC and with composite materials Light Bond, Transbond XT, and Trulock Light Activated Adhesive. Thermal cycling was conducted, and the specimens were dyed with 2% methylene blue, sectioned using a diamond saw Isomet and evaluated under a digital microscope. Microleakage was detected at the enamel-adhesive, adhesive-bracket interfaces from occlusal and gingival margins. Statistical analysis was performed using generalized linear mixed models with beta error distribution and Wilcoxon test. Results: Microleakage was diagnosed in all materials. GC Fuji Ortho LC showed the maximum leakage (p<0,001). The lowest amount of microleakage was detected in composite materials Transbond XT and Light Bond, there was no statistical difference between them. Composite material Trulock Light Activated Adhesive was found to have a higher amount of microleakage than other composite materials. The results indicate that the enamel-adhesive interface exhibited more microleakage in all composite materials than the adhesive bracket–interface. The highest amount of microleakage occurred in gingival region in all materials. Conclusion: The presence of microleakage at the adhesive – enamel interface leads to the penetration of substances from the mouth into enamel surface, thereby causing its irreversible damage.
