Freeze-dried bone in pulpotomy procedures in monkey.

S Fadavi, A W Anderson, I C Punwani

    The Journal of Pedodontics
    |January 1, 1989
    PubMed
    Summary

    Freeze-dried bone effectively promotes calcific barrier formation in amputated pulps, similar to calcium hydroxide. This dental material shows promise for pulp capping procedures in restorative dentistry.

    Area of Science:

    • Dentistry
    • Regenerative Medicine
    • Biomaterials

    Background:

    • Pulp amputation in primary and permanent teeth necessitates effective regenerative materials.
    • Evaluating novel biomaterials for pulp capping is crucial for preserving tooth vitality.

    Purpose of the Study:

    • To assess the histological effects of freeze-dried bone on amputated monkey pulps.
    • To compare freeze-dried bone with established materials like calcium hydroxide and formocresol.

    Main Methods:

    • Histological evaluation of monkey teeth with amputated pulps treated with freeze-dried bone, calcium hydroxide, and formocresol.
    • Control groups included teeth sealed with tin foil and IRM, and intact teeth.

    Main Results:

    • Freeze-dried bone induced complete or partial calcific barrier formation in most treated teeth within three months.
    • Histology showed vital apical thirds and normal odontoblastic cells below the barriers.
    • Calcium hydroxide yielded similar results, while formocresol findings aligned with prior research.

    Conclusions:

    • Freeze-dried bone demonstrates significant potential as a pulp capping agent, promoting dentin bridge formation.
    • Its efficacy is comparable to calcium hydroxide in histological outcomes.
    • Further research may validate freeze-dried bone for clinical applications in endodontics.
