FREQUENTLY ASKED QUESTIONS - Xray
What is the difference between digital X-ray sensors and phosphor plate systems?
Digital sensors provide instant images on a connected monitor within seconds of exposure, with no processing step. Phosphor plate systems use flexible, film-sized plates that are scanned after exposure — offering greater patient comfort for difficult anatomy but adding processing time. Both reduce radiation significantly compared to traditional film.
How much radiation does a digital dental X-ray deliver compared to film?
Digital radiography reduces radiation exposure by 50–80% compared to conventional film radiography, depending on the system and sensor type. CBCT delivers higher dose than 2D intraoral radiography — clinicians should follow ALARA principles and select the smallest field of view that answers the diagnostic question for each patient.
When is CBCT imaging indicated in general dental practice?
CBCT is indicated for implant planning, complex extractions, endo diagnosis in cases with unclear anatomy, orthodontic assessment, airway and TMJ evaluation, and detection of pathology not visible on 2D radiographs. DPS-evaluated clinicians consistently report that CBCT reveals incidental findings that change treatment decisions in a significant percentage of cases.
What should I look for when choosing a digital intraoral sensor?
Key criteria include image resolution measured in line pairs per millimeter, sensor size availability across sizes 0–2, cable durability, direct-to-chair USB vs. wireless connectivity, software compatibility with your practice management system, and the quality and responsiveness of manufacturer support.
How do DPS clinician evaluators rate X-ray and imaging products?
Independent panels of practicing dentists use products in their own offices for approximately 4 weeks, rating on criteria including image clarity and diagnostic confidence, ease of positioning, software integration, and patient comfort. Products scoring 4.3 or above earn the DPS Best Product designation.
