Fuji GI VII
Remineralization VS Recharge
Reminaralization
Property of Glass Ionomer
Recharge
Setting time

Remineralization ,a process in which minerals are returned to the molecular structure, is an effective treatment that often stops or reverses early tooth decay. If your cavity is remineralized, you can avoid a filling.

Water sensitivity, solubility and disintegration
The complete setting reaction takes place in 24 hours there the cement should be protected from saliva in mouth during this period.

GIC are also more resistant to attack by organic acids.

Difficult to manipulate as they are sensitive to moisture imbibition during the early setting reaction.

Recharge of material is ability of material to reload substance from outside sources back into teeth.

What is Fuji GI VII ?
Property of Fuji GI VII
Indication
Advantage VS Disadvantage
Advantage
Disadvantage
1.Very high level of Fluoride release and hence caries inhibition.
2.Chemical adhesion to tooth structure.
3.No etching, No bonding agent.
4.Can be applied when saliva control is not possible.
5.Excellent biocompatibility
6.Easy to use, no isolation needed
7.Radiopacity
8.Good translucency without light-curing
9.Low viscosity
1. Less aesthetic than composite
2. Brittleness
3. Poor strength, Low fracture toughness
4. Water sensitive during setting phase.
5. Short working times and rather long setting times

Conclusion
GC Fuji VII
, another new generation
of glass ionomer cement and surface protectant, has the advantage of very high fluoride release.
The self-bonding, high fluoride releasing GC Fuji VII creates a strong, acid-resistant fused layer.
It is easy to apply due to the low viscosity, and can be used when saliva control is not possible.
GC Fuji Triage (FORMERLY FUJI VII)
: Redeveloped from GC Fuji VII, GC Fuji Triage already has a strong track record of preventing caries in erupting teeth.
GlC sets within 6–8 minutes from the start of mixing.
Film thickness
The film thickness of GICs is similar to or less than that of zinc phosphate cement and is suitable for cementation and luting.
Aesthetics
Conventional glass ionomer cements are tooth-coloured
and available in different shades.

Not as esthetic as composite-resins. In addition, surface finish is usually not as good.
Adhesion
The shear bond strength of conventional glass ionomer cements to conditioned enamel and dentin is relatively low.

Conditioning therefore plays a greater role in achieving effective bonding with the resin-modified glass ionomer cements.
Margin adaptation and leakage
The coefficient of thermal expansion of conventional
glass ionomer cements is close to that of dental hard tissues and has been cited as a significant reason for the good margin adaptation of glass ionomer restorations.
Anticariogenic effect by way of fluoride release
Relative lack of strength and low resistance to abrasion and wear.

Low flexural strength but high modulus of elasticity, and are therefore very brittle and prone to bulk fracture.
Biocompatibility
In vitro study, freshly mixed conventional glass ionomer cement was found to be cytotoxic, but the set cement had no effect on cell cultures.
Physical strengths
An initial release fluoride up to 10 ppm and a constant long-term release of 1 to 3 ppm over 100 months was reported . This release was evidenced to be capable of secondary caries prevention.
Advantage
Disadvantage
Intrinsically adhesive

Fluoride release but this does not guarantee freedom from 2° decay

Similar coefficient of thermal expansion to tooth
Considerably weaker than amalgam and composite

Tendency to crack worsened by early instrumentation

Silver containing materials offer little improvement in physical properties

Some materials radiolucent
1. Fissure protection.
2. Root surface protection.
3. Hypersensitivity prevention and control.
4. Protection for immature enamel.
5. Temporary filling of endodontic access.
6. Intermediate restorations.

Fluoride releasing
Recharged
- The recharging of sealant materials in this study was designed to simulate professional fluoride application using APF, whereas simulation of sealant recharge from daily brushing using a fluoride dentifrice would have more clinical relevance

- In vitro studies have shown that fluoride containing dental materials can be recharged by fluoridated products. This may contribute to their long-term effectiveness in caries inhibition
Antimicrobial properties
- The only surface protectant with antimicrobial properties

- It forms a semipermeable skin that along with its high fluoride levels, helps keep acid attack and bacteria at bay while allowing calcium and phosphate ions to pass through to strengthen the tooth

- An initial fluoride “burst” effect is desirable, as it will reduce the viability of bacteria that may have been left in the inner carious dentin and induce enamel/dentin remineralization
Remineralization & Inhibit Demineralization
- Allows remineralization of enamel

- Although a study results indicate that higher fluoride release of GICs was not able to reduce the amount of bacterial growth and biofilm formation on the surfaces of these materials when stored in natural saliva, based on another study results a monthly fluoride release consisting of 200-300 µg/cm^2 is sufficient to completely inhibit enamel demineralization

- Has the highest fluoride release of any glass ionomer or resin
- Is six times more than any of the latest glass ionomers
- Provides patients with up to 24 months of fluoride protection every application
- More than just a sealant barrier, the advanced fluoride protection offers your patient protection from secondary caries
- Prevents non-carious lesions from progressing to caries
- Prevents further erosion in rampant caries cases
- Fluoride release can be recharged when the patient uses a fluoridated rinse or dentifrice

- In this study, during the first day following application, high concentrations of fluoride were released from the glass ionomer-based materials used as sealants, but not from the other materials tested-

The glass-ionomer based sealants Fuji VII and Fuji II LC had significantly higher fluoride release than the other materials at all times tested

- For all materials, the greatest amount of fluoride released occurred at 24 hr. Fluoride release decreased with time, but continued throughout the entire 21-day test period up until recharge

- At 24 hr, Fuji VII released the most fluoride

- Fuji VII and Fuji II LC released significantly more fluoride than the other materials tested at all times measured

- The manufacturers of Fuji VII GIC claim that this material releases much greater amounts of fluoride than other high-strength GICs
