Area of Science:

  • Dental Materials Science
  • Adhesive Dentistry
  • Clinical Research

Background:

  • Operator variability is a significant factor influencing the shear bond strength of dental adhesives to dentin.
  • Understanding the impact of training and experience on bonding performance is crucial for optimizing clinical outcomes.
  • Different dental adhesive systems may exhibit varying susceptibility to operator variability.

Purpose of the Study:

  • To investigate the effect of operator variability on the shear bond strength of adhesives to dentin.
  • To determine the effectiveness of continuing education on improving bonding performance with different adhesive types.

Main Methods:

  • Thirty general practitioners participated in a continuing education course.
  • Participants bonded four adhesive systems (OptiBond FL, ScotchBond Multipurpose Plus, ScotchBond 1, Clearfil SE) to bovine dentin.

  • Shear bond strength tests were conducted before and after a 90-minute lecture on bonding principles, comparing routine vs. new material use.

    • Main Results:

    • Bond strengths generally increased after the educational lecture, with improvements ranging from 15% to 150%.
    • For experienced dentists, all tested materials showed statistically equivalent bond strengths post-lecture, with OptiBond FL being highest.
    • For inexperienced dentists, ScotchBond 1 exhibited lower bond strengths compared to other materials after the lecture.

    Conclusions:

    • Significant operator variability exists in the manipulation of dental adhesive systems.
    • Continuing education can enhance bonding performance across various adhesive materials.
    • Sufficient experience and education enable dentists to achieve reasonable results with different adhesive systems.
