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.
How many line angles does a Class 2 cavity have?
For class II cavity preparation (mesioocclusal or disto-occlusal) 11 line angles and 6 point angles are as follows. The following is the nomenclature for mesio-occlusal cavity (Fig.
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.
How do you do a class 2 amalgam restoration?
Load the amalgam carrier with amalgam from the well; place the amalgam into the occlusal segment of the prepared cavity. Begin condensation using a small condenser to condense a portion of the amalgam into the proximal box area. Place pressure and condense into all line angles, as well as against the matrix band.
Which tooth would receive a Class 2 restoration?
Class II restorations in permanent molars and premolars; 4. Class V restorations in primary and permanent posterior teeth.
Which is an example of a direct restorative dental material for a Class 2 restoration?
Direct restorative dental materials include amalgam, resin-based composite, glass ionomer, resin modified glass ionomer and acrylic.
What type of restoration is required for molars of Class II?
CONCLUSIONS Controlled clinical trials should be conducted to achieve a high level of evidence in this field. However, within the limits of this study, the type of restoration in molars of class II will depend on the amount of healthy tooth structure remaining.
What is Class II cavity?
The cavity has simple contours without undercuts, the walls diverge in occlusal direction. Fig. 13: Cavity prepared for inlay MAKING OF THE FILLING Class II cavity is so-called outline cavity. The contours of the tooth are namely damaged, and therefore we must work with a matrix.
How to prepare the gingival step of a cavity wall?
The gingival wall forms a 90° angle with the pulpal wall. We finish the preparation by smoothening the cavity walls by a fine diamond bur (red code), the outer edge of the gingival step as well as the axial walls may be prepared by enamel chisels. The aim is to remove undermined enamel prisms. Fig. 10: Treating cavity edges with chisels
Is margin elevation necessary for rubber dam invagination on gingival sulcus?
With proper absolute isolation, due to rubber dam invagination on the gingival sulcus, margin elevation was not necessary. Finally, we performed cementing of 2 composite endocrowns (Lava Ultimate CAD/CAM, 3M ESPE, St. Paul, MN, USA) (Figure 3E), with a good point of contact and precise fit, which would have been difficult to reproduce directly.
