Formation of dentin bridge
Calcium hydroxide on dental pulp causes– necrosis – this necrosis is limited - it does not go deep into
dental pulp (CO2 from dental pulp reacts with calcium hydroxide – a barrier of calcium carbonate
occurs – do necrosis can not go deeper). This necrosis is resorbed during the reactive inflammation connective
tissue – (fibrotic tissue) is formed, calcium salts can be deponed here, due to high alcality
new odontoblasts are differenciated and they form new dentin – predentin and mineralized dentin.
This is dentin bridge is formed when the direct pulp capping or pulpotomy is performed.
