Summary

Radiographic evidence of root fillings is the primary risk indicator for apical periodontitis (AP). Smoking, poor dental work quality, and infrequent dental visits also increase AP risk in individuals.

Area of Science:

  • Endodontology
  • Dental Public Health
  • Epidemiology

Background:

  • Apical periodontitis (AP) is a prevalent endodontic disease.
  • Identifying individual risk indicators is crucial for targeted prevention and management.
  • Previous studies have explored various risk factors, but a comprehensive analysis in a specific population is needed.

Purpose of the Study:

  • To identify and evaluate risk indicators for apical periodontitis (AP) in an individual.
  • To determine which factors significantly increase an individual's likelihood of developing AP.
  • To differentiate between direct disease associations and broader risk indicators.

Main Methods:

  • A full-mouth survey was conducted on 613 randomly selected individuals aged 20-60 in Aarhus County.
  • Logistic regression analyses were employed to assess the association between independent variables and the presence of AP.
  • Independent variables included socioeconomic status, dental status, and treatment history.

Main Results:

  • Radiographic evidence of root fillings emerged as the most significant risk indicator for AP.
  • Other statistically associated factors included smoking, multiple secondary caries lesions, inadequate coronal fillings, and infrequent dental visits.
  • In individuals without prior root fillings, regular dental visits and having all teeth were protective, while inadequate fillings increased risk.

Conclusions:

  • Root fillings are the strongest predictor of AP in the studied Danish population.
  • Dental caries, poor restorative treatment quality, smoking, and irregular dental attendance are significant risk factors for AP.
  • Socioeconomic status provided limited additional predictive value for periapical status.
