Summary

This study observed resin-dentin interfaces in monkey teeth using scanning electron microscopy. Dentin bonding systems created a hybrid layer, with resin tag roughness varying based on the bonding agent and cavity depth.

Area of Science:

  • Dental Materials Science
  • Biomaterials Science
  • Scanning Electron Microscopy

Background:

  • Understanding the resin-dentin interface is crucial for durable dental restorations.
  • Dentin bonding systems aim to create a stable bond between tooth structure and restorative materials.
  • In vivo evaluation provides critical insights into the behavior of bonding systems under physiological conditions.

Purpose of the Study:

  • To investigate the in vivo interfacial structures formed by various dentin bonding systems in V-shaped cervical cavities.
  • To analyze the morphology and depth of the hybrid layer and resin tags.
  • To evaluate the influence of different conditioners/primers and etching agents on interfacial integrity.

Main Methods:

  • V-shaped cervical cavities were prepared in monkey teeth.

  • Teeth were restored using several dentin bonding systems.
  • Scanning electron microscopy with argon-ion etching was employed to observe interfacial structures in vivo.
  • The effects of 37% phosphoric acid gel and acidic primers (maleic acid/HEMA) were specifically examined.

    • Main Results:

    • A distinct hybrid layer was observed, with its depth varying based on the conditioner/primer used and decreasing in deeper cavity areas.
    • Resin tags were clearly visualized; their inner structure was rougher than at the tubule orifices.
    • Rougher resin tags were noted in deeper cavity sections when 37% phosphoric acid gel was used.
    • Hemispherical/spherical structures above tubule orifices suggested a mixture of dentinal fluid and extruded bonding resin.
    • Acidic primers containing maleic acid and HEMA failed to remove smear plugs, leaving undissolved particles in tubules.

    Conclusions:

    • The depth and morphology of the hybrid layer and resin tags are significantly influenced by the dentin bonding system and cavity location.
    • The effectiveness of smear layer removal and subsequent interfacial formation varies with different acidic primers and etching agents.
    • Understanding these interfacial characteristics is vital for optimizing dentin bonding strategies and improving restoration longevity.
