Summary

Dentist practice variations in caries diagnosis and restoration replacement are common. Factors beyond clinical data, including dentist training and patient-provider dynamics, explain these differences.

Area of Science:

  • Dental Practice and Health Services Research
  • Clinical Decision-Making in Dentistry

Background:

  • Significant variation exists in dental practice regarding caries diagnosis and treatment recommendations.
  • Replacement of dental restorations is a key area of practice variation, influenced by patient and dentist factors.

Purpose of the Study:

  • To explore factors, excluding clinical data, that contribute to practice variation in dentistry.
  • Specifically examine reasons for variation in the replacement of dental restorations.

Main Methods:

  • Review of existing literature, including physician studies due to paucity of dental research.
  • Discussion of explanatory models: dentist as self-fulfilling practitioner and dentist as patient's agent.
  • Exploration of clinical judgment development and the role of uncertainty and routines.

Main Results:

  • Physician practice variations offer insights generalizable to dentistry due to similar healthcare provision contexts.
  • Dentist's training experiences influence clinical judgment and practice patterns.
  • Uncertainty in clinical practice and the development of routines are significant factors in practice variation.

Conclusions:

  • Practice variations in dentistry, particularly in restoration replacement, are influenced by non-clinical factors.
  • Understanding dentist-centric models and the impact of uncertainty can help explain and potentially mitigate practice variations.
  • Further research comparing medical and dental practice variations is warranted.
