2. Sedative to the pulp
3. Easily manipulated

Zinc Oxide Eugenol Disadvantages

1. Low Strength
2. High Solubility
3. Unable to be used under composite restorations and indirect restorations cemented with resin or hybrid glass ionomer cements

Zinc Phosphate Advantages

1. Long clinical history
2. Low film thickness
3. Inexpensive
4. High Rigidity
5. Low cost

Zinc Phosphate Disadvantages

1. Initial pulp irritation
2. Mechanical bond only
3. Technique sensitive portioning and mixing
4. Relatively high solubility

Zinc Polycarboxylate Advantages

1. Adheres to tooth structures
2. Non irritating to the pulp
3. Inexpensive
4. Easy to use

Zinc Polycarboxylate Disadvantages

1. Higher Solubility
2. Lower Stregnth
3. Shorter working time

Traditional Glass Ionomer Cement Advantages

1. Chemical adhesion to the tooth
2. Fluoride releasing
3. Easy to mix
4. Moderate Stregnth

Traditional Glass Ionomer Cement Disadvantages

1. History of postoperative sensitivity
2. Moisture sensitive during setting

Hybrid Ionomer Cements Advantages

1. Good Strength
2. Fluoride Releasing
3. Insoluble
4. Chemical adhesion to tooth
5. Less postooperative sensitivity
6. Excellent film thickness

Hybrid Ionomer Cements Disadvantages
