Standardizing dental bond strength testing is crucial for accurate clinical relevance. New ISO guidelines and factors like dentine variation and storage conditions are discussed.

Area of Science:

  • Dental Materials Science
  • Biomaterials Engineering
  • Adhesion Science

Background:

  • Accurate assessment of dental adhesive bond strength is critical for clinical success.
  • Current bond strength testing methods have limitations in interpretation and clinical relevance.
  • Standardization of testing protocols is needed to ensure reliable and comparable results.

Purpose of the Study:

  • To discuss factors influencing bond strength testing in dentistry.
  • To evaluate the clinical relevance of various bond strength testing methods.
  • To refer to the new ISO document (ISO CD TR 11405) for guidance on adhesion testing.

Main Methods:

  • Comparison of tensile and shear test methods for bond strength evaluation.
  • Discussion of dentine substrate variations (remaining dentine thickness, smear layer).

  • Analysis of in vitro test storage conditions (short-term, long-term, thermocycling).

    • Main Results:

    • Microscopical studies indicate some adhesives can achieve dentine-fracturing bond strength under optimal conditions.
    • Variations in dentine substrate and storage conditions significantly influence bond strength values.
    • Tensile and shear test methods yield comparable bond strength values when standardized.

    Conclusions:

    • Standardization of dental bond strength testing is essential for reliable clinical interpretation.
    • Understanding factors like substrate variability and aging is key to predicting clinical performance.
    • Adhesive bond strengths sufficient to fracture dentine are achievable, highlighting the importance of standardized testing.
