German dentists

Area of Science:

  • Dental Science
  • Behavioral Science

Background:

  • German dentists exhibit reluctance towards selective carious tissue removal (SE).
  • Barriers include lack of guidelines and knowledge gaps.
  • Facilitators involve understanding SE's biological basis and evidence.

Purpose of the Study:

  • Investigate reasons for German dentists' reluctance in selective carious tissue removal (SE).
  • Develop and evaluate two interventions to modify dentists' behavior regarding SE.

Main Methods:

  • Ten interviews identified barriers and facilitators for SE adoption.
  • Two interventions were developed: a "Guideline" summarizing scientific statements and a "Tool" simulating a specialized removal instrument.
  • A postal simulation experiment with 1226 dentists tested intervention efficacy.

Main Results:

  • 504 dentists participated (24.9% response rate).
  • Both interventions significantly improved outcome behavior towards SE (p < 0.001).
  • The "Guideline" intervention led to 29.6% behavior change, while the "Tool" intervention resulted in 17.9% change, with no significant difference between them.

Conclusions:

  • Systematically developed behavior-change interventions show promise for increasing SE adoption.
  • Understanding SE barriers and facilitators is key to designing effective interventions for carious tissue removal.
