Calcium hydroxide-based materials show promise for pulp capping, promoting hard tissue bridging in most studies. However, the overall evidence quality is low, necessitating further high-quality research in dental pulp capping.

Area of Science:

  • Dental materials science and restorative dentistry.
  • Investigating the efficacy of pulp capping agents for human teeth.

Background:

  • Pulp capping aims to preserve pulp vitality and promote healing after exposure.
  • This review systematically evaluated studies on pulp capping procedures using microscopic analysis of hard tissue and pulp response.

Discussion:

  • Searches of Medline and Cochrane Controlled Trials Register (CENTRAL) identified 107 studies, with 21 meeting inclusion criteria.
  • The majority of studies (20/21) provided low-level evidence, with only one study offering moderate evidence.
  • Heterogeneity among studies precluded meta-analysis.

Key Insights:

  • Calcium hydroxide-based materials consistently demonstrated hard tissue bridging in studies.
  • Alternative materials, such as bonding agents, yielded less favorable outcomes compared to calcium hydroxide.

  • No studies achieved a high level of evidence, indicating a significant gap in research quality.

    • Outlook:

    • Despite positive findings for calcium hydroxide, the low quality of evidence underscores the need for rigorous, high-quality clinical trials.
    • Future research should focus on improving study design to provide stronger evidence for pulp capping material efficacy.
