The self-fulfilling prophecy in dental prophylaxis

Area of Science:

• Dental Hygiene
• Psychology

Background:

• The self-fulfilling prophecy, where expectations influence outcomes, is a known psychological phenomenon.
• Its specific impact on dental prophylaxis and the patient-therapist relationship requires investigation.

Purpose of the Study:

• To determine if the self-fulfilling prophecy influences dental prophylaxis outcomes.
• To assess its effect on patient and therapist perceptions.
• To evaluate its impact on the quality of prophylactic work.

Main Methods:

• Sixty patients were randomly classified as "good" or "bad".
• Thirty-four dental students treated patients from both groups.
• Dental plaque and gingival inflammation were measured before and after treatment.
• Interviews were conducted with patients and students.

Main Results:

• No significant difference in clinical improvement (plaque, gingivitis) was observed between the "good" and "bad" patient groups.
• Students generally accepted the patient classifications.
• A significantly higher rate of patient drop-outs, missed appointments, and negative notes occurred in the "bad" group.

Conclusions:

• The self-fulfilling prophecy can be triggered by subtle information in patient records.
• This psychological bias can negatively affect the therapeutic relationship and patient management in dental settings.
• Awareness of the phenomenon did not prevent its influence on student therapists.
