Optimizing bitewing examination recall intervals is crucial for maximizing health gain from dental restorative treatment. Shorter intervals may be beneficial, especially for dentists with lower diagnostic accuracy, to improve patient outcomes.

Area of Science:

  • Dental diagnostics and treatment outcomes.
  • Caries process simulation and management.
  • Radiographic interpretation in dentistry.

Background:

  • Bitewing examinations are standard for detecting approximal caries.
  • Recall intervals significantly influence the effectiveness of dental restorative treatments.
  • Varying dentist diagnostic accuracy impacts treatment decisions and patient health gain.

Purpose of the Study:

  • To evaluate how changes in bitewing examination recall intervals affect patient health gain from restorative dental care.
  • To identify optimal recall intervals for bitewing examinations under diverse clinical scenarios.

Main Methods:

  • A computer simulation modeled the caries process on posterior approximal tooth surfaces.
  • Incorporated restorative treatment based on bitewing diagnoses at various intervals.

  • Used data on caries rates, restoration survival, and dentist diagnostic sensitivity (Sn) and specificity (Sp).

    • Main Results:

    • The highest health gain (39.33 UBUs) was achieved with a 7-month recall interval by a dentist with high specificity (0.99) and lower sensitivity (0.23).
    • A dentist with higher sensitivity (0.52) and lower specificity (0.88) experienced a health loss of 16.79 UBUs with intervals over 120 months.
    • Simulation tracked 1000 surfaces over 10 years, considering caries attack rates and restoration longevity.

    Conclusions:

    • Dentists should exercise caution when deciding to restore approximal surfaces based on bitewing radiographs.
    • Current guidelines for bitewing examination intervals may be too permissive for some clinicians.
    • Tailoring recall intervals to individual dentist diagnostic capabilities can optimize patient health outcomes.
