HYDR ATION

When HA coats the surface, it hides the underlying MTA to minimize foreign body reactions and support healing responses of the pulpal or periapical tissue.

Bioactive layer of HA supports reparative dentine formation.

WHY BIOACTIVE BIOCER AMICS (MTA) ARE THE FUTURENuSmile NeoPUTTY® is a dimensionally stable, resin-free root and pulp treatment material that

promotes the formation of hydroxyapatite (HA) to support healing responses. A simplified view of hydroxyapatite formation is shown below in two stages

Calcium hydroxide provides initial high pH for planktonic antimicrobial effects.

The high pH supports the osteogenic response.
