Definitions: ICC= intraclass correlation coefficient; LL= lower limit; UL= upper limit; LMMs= light microscopy measurements; CASMs= computer-assisted measurements; I1.1 and I1.2= first and second measurements of the first investigator (LMM); I2.1= measurement of the second investigator (LMM); I1 and I2= measurements of the first and second investigators (CASM); bias= mean of differences between measurements at specific measurement points.
Measurement points: marginal-buccal (ma-b), marginal-distal (ma-d), axial-buccal (ax-b), incisal (inc).
