Ideal class V restoration

 # For an Ideal class V restoration on a mandibular premolar, which of the following is the MOST IMPORTANT factor when choosing a restorative material?
A. Ease of manipulation of material
B. Esthetics
C. Compressive strength
D. Reaction of gingival tissue

The correct answer is D. Reaction of gingival tissue.

Restorative materials that do not induce gingival tissue reaction should be considered when selecting the proper restorative material for class V restorations.

Esthetics are not a factor because the class V restoration in question is placed at the cervical area of a mandibular premolar and is not within the esthetic zone.

Compressive strength is only required for occlusal restorations or those cavities which are under heavy occlusal load.
