Q

Protective mechanisms of saliva in erosive wear:

A

Ions such as calcium, phosphate, fluoride
buffering acids
reducing demineralisation and enhancing remineralisation

Q

Ho do we manage dental erosion?

A
  • Reduce acids: dietary (amount,t timing, nature, method of consumption. Regurgitated acids (lifestyle modifications, medications, surgery).
  • Strengthen defence mechanism such as fluoride, gum to increase salivary flow
  • protect surfaces (dental bonding, fissure sealant, composite)
  • Monitor
