Optibond Multiuse Bonding Agent demonstrated superior shear bond strength to primary dentin compared to other tested resin adhesive systems. This finding suggests effective esthetic restorations for primary anterior teeth.

Area of Science:

  • Dental Materials Science
  • Pediatric Dentistry
  • Adhesive Dentistry

Background:

  • Primary teeth restorations require durable and esthetic adhesive materials.
  • Evaluating resin adhesive systems for primary dentin and enamel is crucial for clinical success.

Purpose of the Study:

  • To compare the in vitro shear bond strengths of three resin adhesive systems on primary dentin and enamel.
  • To assess the suitability of these systems for esthetic restorations in primary anterior teeth.

Main Methods:

  • 111 primary teeth were used to create dentin and enamel specimens.
  • Three resin adhesive systems were tested for bond strength to primed and unprimed dentin, and etched enamel.
  • Specimens underwent thermocycling before shear bond strength testing using an Instron Testing Machine.

Main Results:

  • Optibond Multiuse Bonding Agent exhibited significantly higher mean shear bond strength to primary dentin (20.5 MPa) compared to Prisma Universal Bond 3 (9.1 MPa) and Scotchbond Multi-purpose (7.3 MPa).
  • Bond strength to primary dentin was comparable to that of primary etched enamel (9.8 MPa).
  • The study indicated that bond strengths to primary dentin may be comparable to those of permanent dentin and enamel.

Conclusions:

  • Resin adhesive systems can achieve bond strengths to primary dentin that are comparable to primary enamel.
  • These findings suggest that modern adhesive systems offer reliable options for esthetic restorations in primary anterior teeth.
  • The results support the confident use of these materials in pediatric restorative dentistry.
