Summary
This study presents a visible light-curing calcium hydroxide cement. Cements with specific resin matrices (BEMA, EMA, HEMA) show improved calcium ion release, strength, and pH, leading to excellent pulp capping results in dogs.
Area of Science:
- Dental Materials Science
- Biomaterials Engineering
- Restorative Dentistry
Context:
- Calcium hydroxide cements are widely used in dentistry for pulp capping.
- Traditional cements have limitations in handling and setting properties.
- Development of visible light-curing alternatives offers improved clinical efficiency.
Purpose:
- To evaluate the impact of different resin matrices on the properties of visible light-curing calcium hydroxide cement.
- To assess calcium ion (Ca2+) release, compressive strength, and pH stability.
- To determine the clinical efficacy of the developed cement in pulp capping procedures.
Summary:
- A novel visible light-curing calcium hydroxide cement was formulated using BEMA, EMA, and HEMA in the resin matrix.
- The resin matrix significantly influenced Ca2+ release, compressive strength, and pH of the set material.
- The optimized cement demonstrated excellent dentin bridge formation in a canine pulp capping model at 70 days.
Impact:
- This research introduces a promising visible light-curing calcium hydroxide cement with enhanced properties for direct pulp capping.
- The findings provide valuable insights into resin matrix selection for optimizing dental cement performance.
- Successful clinical outcomes suggest potential for improved regenerative endodontic procedures and reduced treatment failures.
