Assessing Enamel Thickness to Estimate Interproximal Reduction: A CBCT-Based Study.

Objectives: The aims of this study were to (1) estimate the mesial and distal proximal enamel thickness available (PETa), (2) estimate the proximal enamel thickness remaining (PETr) on the basis of planned IPR, and (3) assess PETr-associated risks with varying IPR amounts.

Materials And Methods: A cross-sectional study was conducted using CBCT scans. PETa was estimated using on-demand software.
