Prevest Crysta Bioactive is a radiopaque, Hydroxyapatite Modified-Glass lonomer Cement for restoration of primary teeth, core build up, restoration of class I, limited class II cavities and as a base and liner material. Hydroxyapatite provides a positive environment and indirectly decreases the caries susceptibility of individuals. It has excellent tooth adhesion, sustained fluoride release, high compressive strength and mineralizing potential.

Indications :-

• Core build-up
• Restoration of primary teeth
• Cases where radiopacity is required
• Temporary endodontic fillings
• Class I, limited Class II, temporary fillings, etc.
• As a base or liner
• Intermediate restoratives and base material for class I and II cavities using the sandwich technique

Advantages :-

• Anticariogenic
• Tooth coloured
• Accelerated remineralisation
• Excellent chemical bonding to dentin and enamel
• Radiopaque for easy post operative diagnosis

Features :

• Fluoride release
• High compressive strength
• Excellent tooth adhesion
• The film thickness of just 15 microns
• Radiopaque
• Low solubility
• Long term clinical data

Key Specifications :

Powder : Fluoro alumina silicate glass

Liquid : Polyacrylic acid liquid normal viscosity

Setting time - 1:30 to 2:00 minutes from start of mixing

Shelf Life : 3 years from the date of manufacturing.

Storage Conditions :

Store at temperature between 10°C to 24°C.

Close the cap carefully after use. Keep away from moisture.

Shelf life not affected after opening if stored in a cool dry place.

Direction to Use :

1. POWDER AND LIQUID DISPENSING :

The recommended powder to liquid ratio is 2 level scoops of powder to 2-3 drops of liquid.

For accurate dispensing of powder, lightly tap the bottle against the hand. Do not shake or invert.

Hold the liquid bottle vertically and squeeze gently.

Close bottles immediately after use.

Shake the powder bottle occasionally.

2. MIXING :

Dispense powder and liquid onto pad or glass slab. Divide the powder into 2 equal parts.

Mix the first portion with all of liquid for 15-20 seconds.

Incorporate the remaining portion and mix

the whole thoroughly for 20 seconds.

3. RESTORATIVE TECHNIQUE :

Prepare tooth using standard techniques. Extensive mechanical retention is not necessary. For pulp capping, use ApaCal Art / Cal LC as a base or liner.

Wash and dry but DO NOT DESICCATE. CRYSTA DENTIN CONDITIONER is recommended to remove the smear layer.

Mix the required amount of cement. Higher temperatures will shorten working time.

Transfer cement to the preparation using a suitable placement instrument. Avoid air bubbles.

Form the contour.

Setting time is 1:30 to 2:00 minutes from start of mixing.
