Study Notes
Base and Lining Materials
- One of the reasons for using base and lining materials is to prevent injuries to the pulp-dentin from restorative materials.
- An ideal lining material should have the property of being impermeable to prevent injuries to the pulp-dentin from restorative materials.
- One of the functions of a liner or base material is to protect the pulp-dentin from restorative materials.
Desirable Properties of Lining Materials
- A desirable property of an ideal lining material during insertion of the restoration is that it should be flowable and adaptable to the cavity contours.
- An ideal lining material should have a sealing ability to improve the marginal seal and reduce marginal leakage around the restoration.
Functions of Cement Base
- The function of a cement base in dental restorations is to reduce marginal leakage around most filling materials and thus reduce post-operative sensitivity.
- A cement base is used to reduce marginal leakage around most filling materials.
Liners and Metallic Restorations
- The need for liners is greatest with metallic restorations that are not well bonded to tooth structure.
- This is because metallic restorations that are not well bonded to tooth structure have a higher risk of pulp-dentin injuries.
Zinc Phosphate Cement
- The component that serves to slow down the setting reaction in zinc phosphate cement is phosphoric acid.
- The main component of the liquid in zinc phosphate cement is phosphoric acid.
