Summary

Composite resin restorations showed less microleakage in root surfaces compared to amalgam and glass ionomer materials. This finding is crucial for durable dental restorations and preventing secondary decay.

Area of Science:

  • Restorative Dentistry
  • Dental Materials Science

Background:

  • Microleakage at the tooth-restoration interface is a significant factor in the longevity of dental restorations.
  • Understanding the marginal integrity of different restorative materials is essential for clinical success.

Purpose of the Study:

  • To compare the microleakage of composite resin, amalgam, and glass ionomer materials when used as root surface restorations.
  • To evaluate the effectiveness of these materials in preventing fluid penetration into dentinal tubules.

Main Methods:

  • Freshly extracted single-rooted teeth were prepared with four distinct cavities on the root surface.
  • Each preparation was restored with one of the tested materials: composite resin, amalgam, or glass ionomer.
  • Specimens underwent thermocycling followed by dye penetration, and transverse sections were microscopically analyzed for microleakage.

Main Results:

  • Composite resin restorations exhibited significantly less microleakage into dentin compared to amalgam restorations.
  • Glass ionomer restorations also showed more microleakage than composite resin.
  • The interface between restorative materials and tooth structure was assessed for dye penetration.

Conclusions:

  • Composite resins demonstrate superior marginal integrity and reduced microleakage in root surface restorations compared to amalgam and glass ionomers.
  • These findings suggest composite resins may offer better protection against secondary caries and improve restoration longevity in root surface applications.
