Tricalcium phosphate (TCP) shows potential as a pulp-capping agent, inducing significant reparative dentin formation. However, it also resulted in the highest inflammatory response compared to calcium hydroxide in this canine study.

Area of Science:

  • Biomaterials Science
  • Dental Materials
  • Regenerative Dentistry

Background:

  • Pulp capping aims to preserve dental pulp vitality.
  • Calcium hydroxide is a traditional pulp-capping agent.
  • Novel biomaterials are being investigated for improved outcomes.

Purpose of the Study:

  • To evaluate tricalcium phosphate (TCP) as a direct pulp-capping agent.
  • To compare the histologic response of TCP with calcium hydroxide.
  • To assess reparative dentin formation and inflammatory response.

Main Methods:

  • Class I and V cavities prepared in beagle dogs.
  • Minimal pulp exposures created surgically.
  • Teeth capped with tricalcium phosphate (TCP), calcium hydroxide, or a 1:1 mixture.

  • Histologic evaluation after 70 days.

    • Main Results:

    • Tricalcium phosphate (TCP) demonstrated the highest percentage of reparative dentin formation.
    • TCP also precipitated the highest mean inflammatory response.
    • The 1:1 mixture showed intermediate results.

    Conclusions:

    • Tricalcium phosphate (TCP) exhibits potential for stimulating reparative dentinogenesis.
    • Further research is needed to mitigate the inflammatory response associated with TCP.
    • TCP may offer an alternative to calcium hydroxide in specific clinical scenarios.
