Table 3 Prioritization of outcomes.

Primary outcome: (Modified USPHS)

Anatomic form

Clinical evaluation

Alfa: Anatomic form ideal

Bravo: Restoration is under-contoured, without

dentin or base exposure.

Charlie: Restoration is under-contoured, without dentin or base exposure.restoration need replacement

Secondary outcomes

Color match

Clinical evaluation

Alfa: Matches tooth

Bravo: Acceptable mismatch

Charlie: Unacceptable mismatch

Marginal discoloration

Clinical evaluation

Alfa: No discoloration

Bravo: minor marginal discoloration without staining toward pulp

Charlie: Deep discoloration with staining toward pulp

Marginal adaptation

Clinical evaluation

Alfa: Closely adapted, no visible crevice

Bravo: Visible crevice, explorer will penetrate

Charlie: Crevice in which dentin is exposed

Secondary Caries

Clinical evaluation

Alfa: No active caries present

Bravo: Non-cavitated active caries is present in contact with the restoration

Charlie: Cavitated active caries is present in contact with the restoration

Surface Texture

Clinical evaluation

Alfa: As smooth as the surrounding enamel

Bravo: Surface rougher than enamel, clinically acceptable

Charlie: Surface unacceptably rough

Marginal Integrity

Clinical evaluation

Alfa: Restoration adapts closely to the tooth structure

Bravo: A visible crevice

Charlie: The explorer penetrates into the crevice

Postoperative sensitivity

Clinical evaluation

Alfa: No post-operative sensitivity

Bravo: Short term and tolerable post-operative sensitivity

Charlie: Intolerable post-operative sensitivity
