Background and Objective: The polymerization of resin component and ionic activity of resin modified glass ionomer cement (Fuji II LC) is reduced due to present of resin that cause shrinkage and microleakage. This study aimed to evaluate the effect of chitosan and Fuji II LC compared to Activa on microleakage characteristics of dentin.
Methods: In this experimental study, 30 premolars, free of decay, restoration, cracks, and fractures (as assessed by light cure), extracted for orthodontic purposes, were used. The study consisted of three separate groups of samples. Group 1: 10 teeth treated with Fuji II LC (negative control), Group 2: 10 teeth treated with Activa (positive control), and Group 3: 10 teeth treated with chitosan added to Fuji II LC. Class V cavities were made on the buccal surfaces and restorations were performed in all groups according to the manufacturer's instructions. Two coats of nail polish were applied to the restoration in a 1 mm area near its margin. The teeth were thermocycled for 30 seconds in a water bath at 5-55±1-2°C (500 cycles). The samples were then incubated in 2% methylene blue for 24 hours. The teeth were bisected using the buccolingual method and then examined.
Findings: There was significant microleakage in Fuji II LC (0.828) and Chitosan-Fuji II LC (0.259) and between Fuji II LC and Activa (0.207). The highest amount of microleakage was found at the gingival margin.
Conclusion: The results of the study showed that Activa and the addition of chitosan to Fuji II LC had a positive effect on microleakage, while Fuji II LC showed the highest microleakage with a significant negative difference.
