Abstract
Background and Aim: This study aimed to compare the microleakage of an adhesive fissure sealant (AFS), a flowable composite resin (FC), and a resin-modified glass ionomer (RMGI) in permanent teeth.
Materials and Methods: This in vitro, experimental study was conducted on 45 extracted posterior teeth with sound fissures. The teeth were randomly divided into 3 groups (n=15). The occlusal fissures were sealed with Beautisealant AFS without etching and bonding in group 1, with Beautifil FC after 37% phosphoric acid etching in group 2, and with Fuji II LC RMGI in group 3. The teeth underwent 500 thermal cycles (5-55°C), and their apices were sealed with wax. They were then immersed in 2% methylene blue for 24 hours. Next, the teeth were sectioned buccolingually and inspected under a stereomicroscope to measure the dye penetration depth as an indicator of microleakage. Data were analyzed by ANOVA, Chi-square test, and Scheffe test (alpha=0.05).
Ethical consideration: The study was approved by the ethics committee of Hamadan University of Medical Sciences (IR.UMSHA.REC.1399.728).
Findings: The microleakage score of RMGI was significantly higher than that of AFS and FC (P<0.05), while the microleakage scores of FC and AFS were not significantly different (P=0.330).
Conclusion: The AFS showed a sealing ability comparable to that of FC, and can be used as an alternative to FC due to its fewer application steps.
