Summary

This study aims to assess the agreement between new computer software using dental photographs, digital spectrophotometer and the visual technique, in achieving accurate resin composite shade matching.

Conditions

  • Shade Matching

Interventions

DEVICE

Computer-Assisted Software

A standardized Computer-assisted photographic shade-matching workflow will be employed using a novel photo-analysis software that first receives the photos and balances each photo to suppress unrealistic colors using a standard gray reference card (WhiBal; Michael Tapes Design), with nominal colorimetric targets of L\* =75, a\* = 0, b\* = 0, will be included in every photograph within the plane of the teeth. The Photo is firstly captured with a Nikon D3400 DSLR crop-frame camera (Nikon Corp) mounted on a stable tripod to avoid movements during capturing the photo and set the proper angulation and parallelism. All camera parameters will be standardized. The program establishes a pixel-to-metric conversion scale (cm) from known distances and overlays orthogonal reference axes to fix landmark orientation and reproducible measurement geometry. Using these guides, tooth height and width are annotated, and the region of interest is consistently defined at the central area of the middle third.
