Gluma/Pekalux and Scotchbond 2/Silux bonding agents effectively prevented microleakage in teeth margins. Universal Bond/Prisma Micro-fine showed less effectiveness in this 24-hour study comparing dentin bonding agents.

Area of Science:

  • Dentistry
  • Dental Materials Science
  • Adhesive Dentistry

Background:

  • Microleakage is a significant concern in restorative dentistry, potentially leading to secondary caries and pulpal issues.
  • Third-generation dentin bonding agents represent advancements in achieving reliable tooth-restoration interfaces.

Purpose of the Study:

  • To compare the microleakage efficacy of three distinct third-generation dentin bonding agents.
  • To evaluate the performance of Gluma/Pekalux, Scotchbond 2/Silux, and Universal Bond/Prisma Micro-fine in sealing dentin-cementum margins.

Main Methods:

  • Freshly extracted human teeth were utilized for the in vitro study.
  • Three different dentin bonding agents were applied according to manufacturer instructions.
  • Microleakage was assessed at the cementum/dentin margins after a 24-hour period.

Main Results:

  • Gluma/Pekalux demonstrated superior performance in preventing microleakage.
  • Scotchbond 2/Silux also exhibited high efficacy in inhibiting microleakage.
  • Universal Bond/Prisma Micro-fine showed a comparatively higher extent of microleakage at the tested margins.

Conclusions:

  • Gluma/Pekalux and Scotchbond 2/Silux are more effective than Universal Bond/Prisma Micro-fine in preventing 24-hour microleakage.
  • The choice of dentin bonding agent can significantly impact the marginal seal of dental restorations.
  • Further research may explore long-term microleakage and other properties of these agents.
