Is Vitrebond radiolucent?
The conventional glass ionomer cement, Ketac-Bond, was more radiopaque than the three resin-modified glass ionomer cements. Of the three resin-modified glass ionomer materials, Vitrebond was the most radiopaque and Fuji Lining LC was the least radiopaque.
Which GIC is used for restoration?
GIC are clinically attractive dental materials and have certain unique properties that make them useful as restorative and adhesive materials….Table 2.
What is the primary purpose of calcium hydroxide?
What is the primary purpose for placing calcium hydroxide? To promote reparative dentin as a barrier between pulp and restoration.
What is zinc phosphate cement?
Zinc phosphate cement the one of the oldest and widely used cements, and is commonly used for luting permanent metal restorations and as a base. It is a high-strength cement base, mixed from zinc oxide powder and phosphoric acid liquid.
Why is Vitrebond used?
Vitrebond Usually Replaces Calcium Hydroxide Under a traditional amalgam restoration, calcium hydroxide has long been used – often with overcoatings of copal varnish – as the base for the restoration. Calcium hydroxide’s main advantage is its capacity for stimulating the growth of secondary or reparative dentin.
What is Vitrebond made of?
Vitrebond™ is a light-cured, resin-modified glass ionomer (RMGI) liner/base material. It is recommended for use as a liner or base under composite, amalgam, metal and ceramic restorations. It is not indicated for direct pulp capping.
What are the 9 types of GIC?

Is GIC a permanent filling?
GIC fillings are permanent fillings. They stay for quite a long duration (depending on your type of food intake, supari, tobacco, etc.).
What is the pH of calcium hydroxide?
Estrela and Figueiredo13 state that calcium hydroxide is a white alkaline (pH 12.8) powder with poor solubility in water (solubility of 1.2 g.L–1 of water at 25 °C). It is a strong base obtained by calcining calcium carbonate until it transforms into calcium oxide (quicklime).
How do you calculate the pH of calcium hydroxide?
Calcium hydroxide in water at 25 °C. 2. Calcium hydroxide in a buffered solution with a pH = 13.00 + Y where Y = the last two digits of your Student ID Number divided by 100. (If your Student ID Number is 100123456, then the pH = 13.56.)
What are the properties of zinc phosphate cement?
Physical properties Diametral tensile strength of approximately 5.5 MPa. It has a modulus of elasticity of approx. 13.7 gigpascales. The resistance to compression and traction vary with the P / L ratio, which is why it recommends that the ratio be 1.4 g of powder per 0.5 ml of liquid.
What is the use of zinc phosphate?
It is commonly used for luting permanent metal and zirconium dioxide restorations and as a base for dental restorations. Zinc phosphate cement is used for cementation of inlays, crowns, bridges, and orthodontic appliances and occasionally as a temporary restoration.
How do you place a Vitrebond?
Just click, mix and use – it’s that easy!
- Dispense desired amount of liner/base onto.
- mixing pad. One to two clicks of material.
- are sufficient.
- Use spatula to mix liner material.
- Apply Vitrebond™ Plus liner / base to dentin.
- Light-cure for 20 seconds.

What are the advantages of GIC?
Low risk. Term deposits and GICs are generally considered safe investments because the principal amount is always safe (if you invest $500, you will get your $500 back). If you put your money into a Servus GIC, your deposits are 100% guaranteed by the Credit Union Deposit Guarantee Corporation.
What is the conductivity of calcium hydroxide?
In this study the conductivity of aqueous and nonaqueous solutions of calcium hydroxide was measured. The conductivity values for saturated solutions of calcium hydroxide in water was 7.3+/-3 mS/cm.
What pH is calcium hydroxide?
Estrela and Figueiredo13 state that calcium hydroxide is a white alkaline (pH 12.8) powder with poor solubility in water (solubility of 1.2 g.L–1 of water at 25 °C).
What is the compressive strength of zinc phosphate cement?
Among the cements with a primary consistency tested, a zinc phosphate cement had the highest values of compressive strength (117 MN/m2) and modulus (13,700 MN/m2); however, a zinc polyacrylate cement had the highest tensile strength (12.6 MN/m2).
What are the properties of zinc phosphate cements?
The zinc phosphate cements were characterized by high values of modulus of elasticity and by plastic deformations less than 0.2%. The polycarboxylate cements were more flexible and also exhibited large plastic deformations.
