Summary

Direct pulp capping with an adhesive system showed inflammation and no healing. Calcium hydroxide, however, promoted pulp repair and dentin bridge formation in this human tooth study.

Area of Science:

  • Dental Materials Science
  • Restorative Dentistry
  • Pulp Biology

Background:

  • Direct pulp capping is a vital clinical procedure.
  • Assessing new materials for pulp capping is crucial for successful treatment outcomes.

Purpose of the Study:

  • To compare the human pulp response to direct capping with an adhesive system versus calcium hydroxide.
  • To evaluate responses at both short and long experimental durations.

Main Methods:

  • Fifty-one human premolars underwent controlled pulp exposures.
  • Pulps were capped with either Scotchbond Multi-Purpose Plus (SBMP-P) or calcium hydroxide.
  • Teeth were restored and processed for light microscopic examination after 9-204 days.

Main Results:

Related Experiment Videos

  • SBMP-P induced short-term inflammation and failed to promote healing or dentin bridge formation long-term.
  • Calcium hydroxide stimulated early pulp repair and consistent dentin bridging.
  • Bacterial infiltration and micro-abscesses were noted in three cases with SBMP-P.

Conclusions:

  • Adhesive systems like SBMP-P may elicit adverse pulp responses.
  • Calcium hydroxide remains a reliable material for direct pulp capping, promoting healing and dentinogenesis.
  • Further research into adhesive systems for direct pulp capping is warranted.
