Advantages: very small particles allow for excellent aesthetic effects and ease of polishing; the increased amount of filler had a positive effect on the abrasion resistance; the material is characterized by spontaneous adhesion to the tooth tissues, which eliminates the need for etching and bonding (optimal adhesion is ensured by the simultaneous use of Cavity Conditioner (1) or (2)Dentin Conditioner; Another positive feature of Fuji II LC is its hydrophilicity – it allows to obtain excellent results in cases where the use of a rubber dam is not possible, when the edges of the cavity are in the dentine and the enamel prisms cannot be etched properly; the material is also characterized by good contrast on X-ray images, which facilitates postoperative diagnosis.
Indications: initially it was mainly recommended as a material for filling cavities of class III and V and in deciduous teeth, now it is a material with many applications, including as a base and material for the tooth core build-up.
Fuji II LC is easy to apply and manipulate.
Available packaging: powder 15g x 3 (A2, A3, B3), liquid 6.8ml x 2.
(1)Cavity Conditioner (GC) / op. 5.7 ml – preparation for conditioning the cavity. It is a mildly-acting 20% polyacrylic conditioner designed to remove the smear layer and prepare the surface of the tooth tissues. Effectively cleans the surface of the cavity in order to obtain optimal chemical adhesion, creates mechanical retention, reduces the risk of post-treatment hypersensitivity, and its blue color allows for better control during application.
(2)Dentin Conditioner (GC) / op. 23.8 ml – preparation for conditioning the cavity. It is a 10% solution of polyacrylic acid intended for cleaning the surface of the cavity in order to improve the adhesion of the glass ionomer. It leaves the projections of the smear layer in the lumen of the tubules, which reduces the risk of postoperative hypersensitivity. The preparation improves the marginal tightness, which has a positive effect on the durability of the filling. It has a blue tint, which allows better control during application.
