Study Notes
MTA Modification
- Theracal: a modification of MTA with added resin
- Bioaggregate: a modification of MTA with nano particles
- Biodentin: a modification of MTA in capsule form
Characteristics of MTA Modifications
- Less solubility than traditional MTA
- Lower solubility than traditional MTA
- High antimicrobial action
- Compressive strength similar to mechanical properties of dentin
- Response to pulpal protection and sealing of dentin tubules
Dental Pulp Functions
- Formative: involved in tooth development
- Nutritive: provides nutrients to the tooth
- Sensory: involved in sensing pain and temperature
- Defensive: protects the tooth from injury
Dental Pulp Irritation
- Caused by direct pulp capping
- Results in pain and inflammation
Dental Pain Theory
- Hydrodynamic Theory: pain caused by fluid movement in dentinal tubules
Actual Cutting in Dentin
- Every square millimeter of dentin cut exposes 30,000 to 45,000 dentinal tubules
- Leads to pulpal tissue irritation
Bioactive Materials
- Materials that elicit a reparative response from the dental pulp
- Formation of hydroxyapatite crystals (Ca silicate)
- Examples: fast set, soluble, and bioactive materials that have an irritating action on the pulp
