Study Notes
Direct Pulp Capping
- Direct pulp capping is suitable for healthy pulps exposed by trauma, restorative procedures, or reversible pulpitis, especially for immature permanent teeth.
- Calcium hydroxide was historically the preferred dressing agent for pulp exposures, but recent studies suggest that MTA, Biodentine, and other bioceramics are viable alternatives.
- MTA is the most intensely studied bioceramic for pulp capping, showing success rates up to 97%, especially for immature teeth.
- Studies show that MTA is more successful than calcium hydroxide for pulp capping, with success rates of 78% and 60% respectively.
- Although MTA can cause tooth discoloration, newer bioceramic materials pose a lower risk.
- Tricalcium silicates, like MTA and Biodentine, are often preferred over calcium hydroxide for pulp capping, showing better overall results.
- Biodentine's physical properties resemble dentin, providing a similar structure.
- There is no significant difference in success rates between MTA, Biodentine, and other tricalcium silicate cements like NeoMTA Plus.
Hemostatic Agents and Disinfectants
- The success of direct pulp capping depends on minimizing tissue toxicity, inducing mineralization, and sealing the cavity from bacteria.
- Controlling hemorrhage is crucial for successful pulp capping.
- Ideal hemostatic agents should also have antibacterial properties.
- Studies show that 0.9% saline, 2% chlorhexidine, and 5.25% sodium hypochlorite are all effective hemostatic and disinfecting agents for pulp exposures.
- The use of 5.25% to 6% sodium hypochlorite for 1 to 10 minutes is recommended for hemostasis in carious pulp exposures.
- When treating carious pulp exposure, controlling bleeding can be difficult due to inflammation.
