Summary

Coronal and root caries often occur together in individuals, particularly those with gum recession and attachment loss. Dental fillings can influence the observed relationship between these two types of tooth decay.

Racial differences in periodontal disease and 10-year self-reported tooth loss among late middle-aged and older adults: the dental ARIC study.

Journal of public health dentistry·2017

Area of Science:

  • Dental epidemiology
  • Oral health research
  • Geriatric dentistry

Background:

  • Coronal caries (tooth decay on tooth crowns) and root caries (decay on tooth roots) are common oral health issues, especially in older adults.
  • Understanding the relationship between these two conditions is crucial for effective prevention and treatment strategies.

Purpose of the Study:

  • To examine the association between the prevalence and incidence of coronal and root caries.
  • To identify demographic and clinical factors associated with the simultaneous occurrence of both coronal and root caries in individuals over 65.

Main Methods:

  • A randomly selected sample of adults aged 65+ in North Carolina was surveyed.
  • Dental examinations and interviews were conducted to assess coronal and root caries (decay and filled surfaces).

  • Contingency table analyses and ordinal logistic regression were used to analyze the data.

    • Main Results:

    • Prevalence of coronal and root caries was significantly associated in both Black and White participants.
    • Incidence of both caries types was associated in Black participants but not in White participants.
    • Gingival recession, attachment loss, and baseline lactobacilli levels were associated with developing both types of caries.

    Conclusions:

    • Coronal and root caries tend to co-occur within individuals, though dental restorations may mask this association.
    • The presence of fillings significantly impacts the epidemiological relationship between coronal and root caries, questioning the caries index's disease-definition criteria.
