3. Colour match is satisfactory; there is a clear deviation in colour match that does not affect aesthetics.
4. Colour match is satisfactory; there is a clear deviation in colour match that does not affect aesthetics.
5. Colour match and/or translucency are clinically unsatisfactory. The restoration displays an unacceptable alteration in colour and/or translucency. Restoration needs replacement.

3. Marginal enamel defect <250µm / Crack <250µm / Enamel chipping
4. Multiple cracks / Major marginal enamel defects; gap > 250 µm or dentine or base exposed
5. Cusp or tooth fracture

1. No secondary or primary caries
2. Small and localized: Demineralization / Erosion / Abfraction.
3. Larger areas of: Demineralisation / Erosion / Abrasion / abfraction, dentine not exposed. Only preventive measures necessary
4. Caries with cavitation and suspected undermining caries / Erosion in dentine / Abrasion, abfraction in dentine. Localized and accessible can be repaired.
5. Deep caries or exposed dentine that is not accessible for repair of restoration

1. No clinically detectable gap.
2. Marginal integrity deviates from ideal but could be upgraded to ideal by polishing.
3. Leakage/discoloration is present but limited to border area of margins. Generalized marginal gap >150 µm but <250 µm, easily perceptible on probing but cannot be modified without minor damage to tooth or surrounding tissue, and is not considered to result in long-term negative consequences for tooth or surrounding tissue if left untreated. Presence of several small marginal fractures that are unlikely to cause long-term effects.
4. Localized gap larger than 250 µm, may result in exposure of dentine or base. Repair necessary for prophylactic reasons.
5. Generalized gap larger than 250 µm or restoration is loose but in situ, replacement necessary or large fractures at margins and loss of material is too extensive to be repaired.

1. No marginal staining
2. Minor marginal staining, easily removable.
3. Moderate marginal staining, not aesthetically unacceptable.
4. Pronounced (mainly localized) marginal staining and not removable by polishing; major intervention necessary for improvement. of aesthetics
5. Deep marginal staining (generalized and/or profound), not accessible for intervention.

1. Contact is physiological (dental floss can only be inserted into the interdental space under pressure).
2. Contact is slightly too strong but acceptable. Floss or 25 µm metal blade can only be passed through contact with force/pressure.
3. Contact is weak, a 50 µm metal blade can pass through contact area but not a 100 µm blade, or floss passes very easily with only a slight snap effect. There is no indication for removing/repairing restoration and there is no damage to tooth, gingiva or other periodontal structures. There is no cervical caries, inflammation of the gingival papilla through food impaction, or pocket formation.
4. Contact is weak and a 100 µm metal blade can easily pass through. In addition there are signs of damage to tooth (i.e. cervical caries,). Repair is necessary.
5. Contact is weak allowing damage due to food impaction and demonstrating pain/gingivitis requires immediate intervention. Repair is not feasible and replacement is necessary.

1. Entirely satisfied with aesthetics and function
2. Satisfied with aesthetics and function
3. Minor criticism but no adverse clinical effects.
4. Desire for improvement (aesthetics / function); Reshaping of anatomic form or refurbishing is possible.
5. Completely dissatisfied and / or adverse effects, incl. pain

1. No postoperative hypersensitivity. Normal pulp vitality response.
2. Postoperative hypersensitivity of short duration (less than one week) and no longer present at the baseline assessment. Pulp vitality response normal at baseline assessment (one week after placement).
3. Intense postoperative hypersensitivity of duration greater than one week but less than six-months.
4. Persistent postoperative hypersensitivity. Response to cold stimulus is markedly premature/strong and major intervention is necessary; or there is extremely delayed/weak and unclear or negative sensitivity. Sensitivity level is significantly different from the situation prior to treatment.
5. Negative sensitivity recorded at recall visit despite positive pulp response at baseline, or severe pain is noted. Removal of restoration and immediate root canal treatment is required or the tooth must be extracted.

Race and Ethnicity were not collected from any participant.

1. Luster comparable to enamel
2. Slightly dull, not noticeable from speaking distance.
3. Surface is dull but still acceptable if the surface of the restoration is covered with a film of saliva.
4. Surface is rough and not masked by salivary film. Major re-finishing or veneering is necessary and possible.
5. Surface is unacceptably rough which makes it ugly and/or it retains noticeable biofilm (plaque). Improvement by finishing or veneering is not feasible.
