Why would a dentist place a liner?

Since the 19th century liners have often been placed in cavities in the teeth under the filling material. The liners are thought to protect the living pulp of the tooth from filling materials themselves and also from their potential to allow more heat or cold through than the natural tooth would.

Do liners work for teeth?

For example, while liners can be used to effectively treat a multitude of issues including overlapping teeth and crowding, some more complex issues can only be fixed using braces. If the patient is concerned about the aesthetics of wearing braces, liners may be a better option as they are discreet and invisible.

Why do we use liner?

A liner is defined as a material that is applied in a thin layer, usually 0.5 mm thick, to seal the dentin on the floor and walls of a cavity from the influx of bacteria or irritants from restorative materials and procedures. Additionally, a liner (other than a varnish) may provide some therapeutic benefits.

When and why you should use a liner / base?

By their nature, RMGI liners are typically fluid materials that can adapt more readily to the internal aspects of a cavity preparation. In the past three years, our practice has become accustomed to using RMGI liner/base products with almost every procedure.

Why do I need a reline on my dentures?

Bone begins to be absorbed into the body in a process called resorption. This resorption is a natural and predictable occurrence, but it can make previously well-fitted dentures begin to shift and feel unstable. A denture reline is an easy way to add material to the part of the denture that comes into contact with the gums.

What is in Vitrebond?

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 is glass ionomer used for?

Glass ionomer is essentially a flexible paste, that is used to form a tight seal between the internal tooth (exposed, due to a cavity) and the surrounding environment. It acts as a sealant, allowing the tooth to remain protected.

Do you cure Vitrebond?

Light-cure for 30 seconds. If needed, a second layer up to 2mm may then be placed and cured. Continue with the restorative procedure. Use Vitrebond™ Light-Cure Glass Ionomer Liner/Base to…

Is Dycal a liner or base?

Dycal® Calcium Hydroxide Liner is a two-component, rigid-setting, self-curing material designed for use in direct and indirect pulp capping and as a protective liner under dental adhesives, varnishes, filling materials, cements, and other base materials.

When do you use a dental liner?

Dental cavity liners have historically been used to protect the pulp from the toxic effects of some dental restorative materials and to prevent the pain of thermal conductivity by placing an insulating layer between restorative material and the remaining tooth structure.

How does glass ionomer bond to tooth?

Micromechanical interlocking, caused by glass-ionomers being self-etching due to the polyacid component. True chemical bonding. This involves ionic bonds being formed between the carboxylate groups on the polyacid molecules and calcium ions in the tooth surface [51].

Is Vitrebond a base?

is a resin modified glass ionomer (RMGI) liner/base material, its composition and curing mechanism extensively described in the literature. It is recommend for use as a liner or base under composite, amalgam, metal and ceramic restorations. Vitrebond Liner/Base is not indicated for direct pulp capping.

What are the advantages of glass ionomer cement?

Glass ionomer cements exhibit a number of advantages over other restorative materials. By bonding a restorative material to tooth structure, the cavity is theoretically sealed, protecting the pulp, eliminating secondary caries and preventing leakage at the margins.

How does glass ionomer bond to teeth?

Can a vitrebond be used as a base?

It is recommend for use as a liner or base under composite, amalgam, metal and ceramic restorations. Vitrebond Liner/Base is not indicated for direct pulp capping. If a pulp exposure occurs, cover the exposure with a calcium hydroxide material.

What makes vitrebond a good seal on dentin?

Vitrebond provided a good seal on dentin, which is highly desirable for preventing access of microorganisms to the site of the pulp exposure. However, the preferred method of pulp capping found was the use of a hard setting Ca(OH) 2 material on the exposure followed by application of a layer of Vitrebond liner/base.

Can a vitrebond liner be used for pulp capping?

Pulp Protection: Vitrebond liner/base is not indicated for direct pulp capping. If a pulp exposure occurs, cover the exposure with a calcium hydroxide material. Place the Vitrebond liner/base over the calcium hydroxide and surrounding dentin to seal and protect the exposure. 2. Dentin Pretreatment: Dentin pretreatment is not recommended.

How does calcium hydroxide and vitrebond trad work?

2material on the exposure followed by application of a layer of Vitrebond liner/base. The calcium hydroxide can help control any possible bleeding, and the Vitrebond layer effectively seals the dentin and provides a mechanically strong base upon which the restorative material is applied.
