Can smartphone cameras be a viable alternative to digital single-lens reflex (DSLR) cameras for dental shade assessment?

Why it matters for dental
Smartphone-based shade matching could reduce capital-equipment spend for solo or small-group practices and change how associates and staff document esthetic cases, but clinical reliability and reimbursement implications remain uncertain.
Key points
- Smartphone cameras eliminate the need for a dedicated DSLR + macro-lens set-up (≈ $1,500–$3,000), lowering the entry cost for shade documentation.
- The study compares ΔE color-difference values between smartphone images and DSLR images against a spectrophotometer reference in 60 anterior restorations.
- No significant difference (p > 0.05) was found in shade-match accuracy between the two camera systems, but ambient lighting protocols and gray-card calibration were required for phones.
- Staff and associates can capture shade data chair-side with existing iOS/Android devices, potentially shortening appointment times and reducing shade-remake rates if validated workflows are adopted.
