Lead aprons and thyroid collars were introduced when dental X-ray systems delivered higher doses, and beam control was limited. That rationale has narrowed. This article examines why routine shielding is being reconsidered in dentomaxillofacial radiography, where evidence still diverges, and what actually reduces dose in modern practice.

Radiation in dentistry isn’t a fear issue — it’s a stewardship issue: every exposure should be justified, dose-optimized, and fully interpreted. This article puts typical dental doses (including CBCT variability) into context and gives dentists a practical framework to image intentionally and document responsibly.

2D dental X-rays and CBCT scans do not compete—they answer different clinical questions. Learn the practical differences between 2D radiographs and CBCT, what each shows, and when 3D imaging changes planning and reduces uncertainty.
