DANB CRFDA Study Tips from Top Performers

1Prioritize Restorative Functions (RF) — the most challenging component with 80 questions and the heaviest clinical content

2For Impressions, practice differentiating material types: alginate vs. PVS vs. polyether properties and uses

3Master temporary crown fabrication steps including material selection, trimming, cementation, and patient instructions

4Review composite layering technique, matrix band placement, and shade selection for RF procedures

5Study sealant placement in parallel with RF bonding procedures since both use acid-etch technique
