What are the steps for cavity preparation?

Cavity preparation, the procedure used to remove demineralized enamel and infected dentin consists of four steps:

  1. Opening a cavity or removing a poorly fitting restoration.
  2. Removing infected dentin.
  3. Evaluating residual tooth tissue and removing unsupported or structurally compromised enamel.
  4. Finishing cavity margins.

What is class 2 amalgam preparation?

Class II carious lesions occur on proximal surfaces of premolars and molars. They may occur in combination with occlusal (Class I) caries or they may occur alone. In situations where the presence of caries is on the occlusal as well as the proximal surface, a two-surface cavity is prepared.

What is a Class II cavity?

Class II: Cavity on proximal surfaces of premolars and molars (Class II corresponds to surfaces of a posterior tooth you cannot see clinically)

Which of the following steps is completed first cavity preparation?

First, the tooth is prepared by removing dental decay, structurally unstable portions of the tooth, and any other tooth structure that needs to be removed to make room for the filling material. The next step is the placement of the restorative material, which may be any of the following: Composite (resin plastic)

What is a Class 2 dental restoration?

A Class II restoration has to recreate not only the natural contour of the tooth, but also the corresponding proximal contact. Many dentists consider this point, in particular, to be the most demanding part of the treatment.

What is the final step in a cavity preparation?

Final cavity preparation stage…. Definition: Finishing the preparation walls is the further development of a specific cavosurface design and degree of smoothness that produces the maximum effectiveness of the restorative material being used.

What is the final step in cavity preparation?

What is conventional cavity preparation?

The fundamental concepts relating to conventional and modified tooth preparation are the same: (1) all unsupported enamel tooth structure is normally removed; (2) the fault, defect, or caries is removed; (3) the remaining tooth structure is left as strong as possible; (4) the underlying pulpal tissue is protected; and …

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.

Can Dycal be used under composite?

Further studies are necessary to suggest that Dycal can be used without any inhibitions under composite resin restorations, may be in vivo studies with long-term follow-up of the outcome are required.
