GC Gold Label 2 LC / Fuji II LC (Powder-Liquid) Restorative GIC - Mini Pack A2

GC Gold Label 2 LC / Fuji II LC is a Light-Cured Reinforced Glass Ionomer Restorative, featuring resin reinforcement and a triple-cured mechanism that includes light curing, glass ionomer, and resin matrix self-cure [1, 4, 5]. This material is primarily designed for restorative applications in Class III, V, and deciduous teeth [1, 8]. The product is supplied in a Powder-Liquid form, with the specific shade A2 available in a Mini Pack [1, 2, 4, 5].

Beyond its primary use, GC Gold Label 2 LC / Fuji II LC serves as a multipurpose material, indicated for use as a liner, base, and core build-up [1, 8]. Its strontium-based glass ionomer composition provides good radiopacity and snapset characteristics, while also promoting internal remineralization within the tooth structure by mimicking calcium [1]. The material exhibits a surface strengthening effect when placed in a calcium-containing environment like saliva, and forms a consistent, predictable, and long-lasting seal through an ion exchange process with dentin and enamel [1].

The Powder-Liquid formulation allows for a precise mixing protocol, with a recommended total mixing time of 20-25 seconds [1, 2]. It offers a working time of 3 minutes 45 seconds at 23˚C (73.4˚F) and requires a light curing time of 20 seconds [1, 2, 4, 5]. This allows for immediate finishing after light curing, enhancing clinical efficiency [1, 4, 5].

Key Features : 

Light-Cured Reinforced Glass Ionomer Cement indicated for Class III, V, and deciduous teeth restorations, as well as a liner, base, and core build-up [1, 2, 8].
Powder-Liquid mixing method with a standard powder to liquid ratio of 3.2g / 1.0g, allowing for hand mixing [1, 2, 4, 5].
Offers a working time of 3 minutes 45 seconds and a light curing time of 20 seconds, facilitating efficient clinical procedures [1, 2, 4, 5].

1. POWDER AND LIQUID DISPENSING

a) Select shade based on Vita shade guide.  : Vita is a registered trademark of Vita Zahnfabrik, Bad Säckingen, Germany

b) The standard powder to liquid ratio is 3.2g / 1.0g. 1 level scoop of powder to 2 drops of liquid

c) For accurate dispensing of powder, tap the bottle gently. Do not shake or invert

d) Hold the liquid bottle vertically and squeeze gently

e) Close bottles immediately after use

2. MIXING

a) Fluff powder of bottle before dispensing

b) Place one scoop of powder and two drops of liquid on pad. Divide powder in half

c) Spread liquid out into a thin layer (about the size of a half dollar or 3 cm) with plastic spatula

d) Pull half of the powder onto liquid and mix with lapping strokes (like impression material) for 10 to 15 seconds

e) Pull in remaining powder and mix thoroughly to a glossy consistency. Do not exceed 20-25 second total mixing time

3. RESTORATIVE TECHNIQUE

a) Prepare tooth using standard techniques. Extensive mechanical retention is not necessary. For pulp capping use calcium hydroxide

b) Apply GC CAVITY CONDITIONER (10 seconds) or GC DENTIN CONDITIONER (20 seconds) to the bonding surfaces using a cotton pellet or sponge

c) Rinse thoroughly with water. Dry by blotting with a cotton pellet or gently blowing with an air syringe. DO NOT DESICCATE. Best results are obtained when prepared surfaces appear moist (glistening)

d) Mix the required amount of cement. Working time is 3 minutes 45 seconds from the start of mixing at 23°C (73.4°F). Higher temperatures will shorten working time

e) Transfer cement to the preparation using a syringe or suitable placement instrument. Avoid air bubbles

f) Form the contour and place a transparent matrix if required

g) Light cure for 20 seconds using a visible light curing device (470 nm wavelength). Place light source as closely as possible to the cement surface. Note : For cavities deeper than 1.8 mm, use a layering technique

4. FINISHING

Remove matrix and finish under water spray using standard techniques. Note : Apply a final coat of GC Fuji VARNISH (blow dry) or GC Fuji COAT LC (light cure for 10 sec.) or G-COAT PLUS (light cure for 20 sec.).
