Dycal under composite
Dycal may be used as a thin calcium-hydroxide liner in a deep cavity, then covered before composite is bonded.
When can Dycal be placed beneath a composite filling?
Dycal may be used as a thin calcium-hydroxide liner in a deep cavity, then covered before composite is bonded.
What role does a Dycal liner have near the pulp?
Dycal is a liner near the pulp, not a bulk filling. Its set surface needs protection within the restorative protocol.
How is Dycal covered before composite is bonded?
The dentist removes infected dentine, places liner only where indicated, seals it, and layers and cures composite.
When should pain after a Dycal restoration be reviewed?
Return for lingering thermal pain, spontaneous pain, pain on biting, swelling, or a high or broken restoration.
What should you ask about the liner and pulp health?
Ask why a liner is needed, what covers it, and how pulp health was assessed.
Frequently asked questions
Can home care replace an examination?

What determines treatment?
The affected tissue, severity, symptoms, bite, existing restorations, and health history guide treatment.
