Clinical Evaluation of Direct Composite Veneer Restorations

1.Change from baseline to 12 months regarding "Anatomic form"

alpha: The general contour of the restorations follows the contour bravo: the general contour of the restoration does not follow the contour of the tooth charlie: The restoration has an overhang does

Time frame: baseline, 3-month, 6-month,12-month

2.Change from baseline to 12 months regarding "Marginal adaptation"

alpha: Explorer does not catch or has one-way catch when drawn across the restoration/tooth interface bravo: explorer falls into crevice drawn across the restoration/tooth interface charlie: Dentin or base is exposed along the margin

Time frame: baseline, 3-month, 6-month,12-month

3.Change from baseline to 12 months regarding "Surface roughness"

alpha: the surface of the restoration does not have any surface defects bravo: the surface of the restoration has minimal surface defects charlie: the surface of the restoration has severe surface defects

Time frame: baseline, 3-month, 6-month,12-month

4.Change from baseline to 12 months regarding "Marginal staining"

alpha: there is no discoloration between the restorations and tooth bravo: there is discoloration on less than half of the circumferential margin charlie: there is discoloration on more than half of the circumferential margin

Time frame: baseline, 3-month, 6-month,12-month

5.Change from baseline to 12 months regarding "Retention"

alpha: intact bravo: chipped/loss of material charlie: complete loss of crown

Time frame: baseline, 3-month, 6-month,12-month

6.Change from baseline to 12 months regarding "Incisal wear"

alpha: intact bravo: wear of occlusal surface without tooth surface exposure charlie: wear of occlusal surface with tooth surface exposure
