AI Dental X-Ray Cavity Detection Quiz

Answers and explanations appear as you take the quiz.

1. Which type of dental X-ray is the main image for spotting cavities between back teeth?
   • Periapical
   • Bitewing
   • Panoramic
   • Cephalometric
2. An AI tool outlines an early lesion confined to enamel. What does the guide say this means for treatment?
   • A filling is always required
   • The tooth must be extracted
   • Many early enamel lesions can be stopped with fluoride, sealants and diet changes, so the dentist decides based on depth, activity and risk
   • The AI will schedule treatment automatically
3. Which normal radiographic effect near the gumline can look like decay?
   • Cervical burnout
   • Cone cut
   • Tooth numbering
   • Enamel sealing
4. Which two landmarks must the software locate to measure bone levels?
   • Enamel surface and pulp chamber
   • Root tip and crown tip
   • Cementoenamel junction and alveolar crest
   • Gum line and tongue
5. Why do dental AI models usually learn expert consensus rather than true ground truth?
   • Histology or visual confirmation during drilling is rarely available, so labels come from several dentists annotating images
   • Ground truth is illegal to collect
   • Consensus labels are always more accurate than histology
   • The models are trained without any labels
6. How are several FDA-cleared dental radiograph tools generally classified?
   • As autonomous diagnostic devices that replace dentists
   • As computer-aided detection devices that assist the clinician
   • As consumer wellness apps
   • As insurance billing software only
7. What trade-off do some studies report when AI assistance increases sensitivity for early cavities?
   • Images take longer to capture
   • More false positives
   • Lower radiation doses
   • Fewer detected restorations
8. What can the vendor's confidence threshold change about a detection model?
   • The patient's caries risk
   • The balance between sensitivity and false positives
   • The sensor's pixel size
   • The number of teeth in the image
