Kavitan Plus (Кавітан Плюс): Classic Glass Ionomer Cement for Strength and Reliability

Kavitan Plus (Kavitan Plus) from SpofaDental (Kerr) is a high-quality, chemically cured Glass Ionomer Cement (GIC) that has proven to be a reliable and versatile material for a wide range of restorative tasks. Based on the classic powder/liquid system, it provides strong chemical adhesion, excellent biocompatibility, and long-lasting anti-cariogenic action.

The kit (15 g powder + 15 g liquid) is an economical solution for daily clinical practice where simple application and predictable results are valued.

Key Properties and Technologies

Kavitan Plus is a classic, chemically cured Glass Ionomer Cement (GIC) of Type II (restorative), meeting the standards of ISO 9917-1:2007 (Water-based cements). Its clinical advantages are supported by general research into GIC properties.

1. Mechanical Strength

   Type II cements are known for their ability to withstand occlusal stress, making them suitable for Class I (small), Class II (temporary), and Class V restorations.

   • Compressive Strength: Typical values for high-quality GICs in this class range from $150 \text{ to } 250 \text{ MPa}$.

   • Abrasion Resistance: The cement is designed to minimize early wear, which is an important technical advantage, allowing its use for long-term temporary or permanent restorations under moderate stress.

2. Bioactivity and Anti-Cariogenic Action

   One of the most researched advantages of GICs is their ability to release fluoride.

   • Fluoride Release: Kavitan Plus exhibits a sustained fluoride release profile, which is typically highest during the first 24–48 hours and decreases but continues for months.

   • Effect: The released fluoride creates an inhibitory layer in the adjacent tissues, preventing demineralization and promoting remineralization.

3. Adhesion and Marginal Adaptation

   The reliability of Kavitan Plus is based on its ability to form a chemical bond, which minimizes microleakage.

   • Mechanism: The polyacrylic acids of the cement chemically bond with the calcium in the hydroxyapatite of enamel and dentin.

   • Bond Strength: Bond strength to dentin is typically in the range of $3 \text{ to } 8 \text{ MPa}$ with self-adhesion. Although lower than that of bonded composites, this adhesion is bioactive and less sensitive to moisture.

4. Radiopacity

   Kavitan Plus meets the requirements for radiopacity, exceeding the minimum standard set by ISO.

   • Indicator: Radiopacity is expressed in mm of aluminum (Al) equivalent and must be greater than that of enamel (approximately $3 \text{ mm Al}$). This ensures easy detection of secondary caries or defects on radiographs.

Indications for Use

Kavitan Plus is used for a wide range of tasks:

• Permanent Restorations: Filling Class I, Class V, and small Class II cavities (especially when using the ART technique).

• Base and Liner: Use as a liner under composite restorations ("sandwich" technique) to protect the pulp.

• Core Build-up: Forming a stable foundation for indirect restorations.

• Pediatric Dentistry: Restoration of deciduous teeth, caries prevention.

• Temporary Fillings: Long-term temporary filling.

Working Protocol

Kavitan Plus is a powder/liquid system that requires precise dosing:

1. Preparation: Mixing is done on a glass slab or a special pad. Use the recommended ratio (usually 1 scoop of powder per 1 drop of liquid).

2. Mixing: Rapid mixing until a homogeneous, glossy consistency is achieved (about 20–30 seconds).

3. Placement: The material is placed into the cavity.

4. Setting Time: The material has a comfortable working time (up to 2 minutes) and sets quickly.

Kavitan Plus is a time-tested standard of reliability, ensuring long-lasting, biocompatible restorations with added anti-cariogenic protection.
