Summary

Direct pulp capping using a CO2 laser achieved an 89% success rate, significantly higher than the 68% success rate of conventional calcium hydroxide treatment over 12 months.

Area of Science:

  • Dentistry
  • Dental Materials Science
  • Laser Dentistry

Background:

  • Direct pulp capping is a dental procedure to preserve pulp vitality.
  • Conventional treatments, like calcium hydroxide, have variable success rates.
  • Minimally invasive techniques are sought to improve outcomes.

Purpose of the Study:

  • To compare the efficacy of CO2 laser treatment versus conventional calcium hydroxide for direct pulp capping.
  • To evaluate the long-term (12-month) success rates of both treatment modalities.

Main Methods:

  • Two hundred direct pulp capping procedures were performed: 100 with CO2 laser and 100 with calcium hydroxide (control).
  • Vitality was assessed using thermal tests.
  • Pulpal blood flow was measured using laser Doppler flowmetry.
  • Follow-up examinations occurred monthly for 12 months.

Main Results:

  • The CO2 laser group demonstrated an 89% success rate (89 vital teeth out of 100).
  • The conventional calcium hydroxide group had a significantly lower success rate of 68%.
  • Exposure sizes and mean patient age were comparable between groups.

Conclusions:

  • CO2 laser application appears to be a valuable adjunct in direct pulp capping procedures.
  • Laser treatment shows superior outcomes compared to conventional calcium hydroxide in preserving pulp vitality.
