Primary outcome	Measuring devices	Measuring units
Retention	Visual inspection with mirror at 18 inches	Complete retention Mobilization of the restoration Loss of the restoration	Alpha (A) Bravo (B) Charlie (C)
Color match	Visual inspection with mirror at 18 inches	Perfectly matched color shade Unperfected color match. Unacceptable color match		Alpha (A) Bravo (B) Charlie (C)
Marginal integrity	Visual inspection with explorer and mirror, if needed	Absence of discrepancy at probing Presence of discrepancy at probing without dentin exposure Probe penetrates in the discrepancy at probing with dentin exposure		Alpha (A) Bravo (B) Charlie (C)
Marginal discoloration	Visual inspection with mirror at 18 inches	Absence of marginal discoloration Presence of marginal discoloration limited and not extended Evident marginal discoloration penetrated toward the pulp chamber		Alpha (A) Bravo (B) Charlie (C)
Surface texture	Visual inspection with explorer and mirror, if needed	Surface is not rough Surface is slightly rough Surface is highly rough		Alpha (A) Bravo (B) Charlie (C)
Surface staining	Visual inspection with explorer and mirror, if needed	Surface is not staining Surface is slightly staining Surface is highly staining		Alpha (A) Bravo (B) Charlie (C)
Postoperative sensitivity	Ask the patient. "Questionnaire"	Absence of hypersensitivity Mild hypersensitivity Presence of strong and intolerable hypersensitivity		Alpha (A) Bravo (B) Charlie (C)
Secondary caries	Visual inspection with explorer and mirror, if needed	No evidence of caries Evidence of caries along the margin of the restoration		Alpha (A) Charlie (C)
