Abstract. The aim of this in vitro study was to evaluate the microleakage of Fuji Triage glass ionomer in<br>contaminated pits and fissures, and to compare it with the microleakage of resin-based pit and fissure sealant.<br>Sixty-four extracted human premolar teeth were randomly assigned into two main groups according to the fissure<br>sealant used (Fuji Triage or ClinproTM). Each group was divided into four subgroups according to the different<br>surface conditions as follows: (1= dry condition; 2= water contamination; 3= saliva contamination; 4= saliva<br>contamination and air-drying). The teeth were subjected to thermal cycling (500 cycles at 5oC-55oC) with a dwell<br>time of 30 seconds. The teeth were then immersed in 1% methylene blue for 24 hours, embedded in acrylic resin<br>and sectioned longitudinally in a buccolingual direction. The sections were analyzed for microleakage using a<br>stereomicroscope. Microleakage was evaluated on a three-point rating scale and was analyzed using t and<br>ANOVA tests. Both materials, under different conditions, exhibited dye penetration to some extent. However, Fuji<br>Triage cement showed less microleakage in wet conditions compared to ClinproTM group. Whenever wet (water or<br>saliva) contamination is apparent, the use of Fuji Triage cement as a sealing material would be beneficial to<br>decrease microleakage.
