Coronary Artery Disease IV: Preventive Measures

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...

Preventing root caries in institutionalized elders is crucial. Silver diamine fluoride (SDF) and fluoride varnishes significantly reduced new root caries compared to oral hygiene instruction alone.

Area of Science:

  • Geriatric Dentistry
  • Cariology
  • Preventive Dentistry

Background:

  • Root caries is a prevalent issue among institutionalized elderly individuals.
  • Effective preventive strategies are essential to mitigate the incidence of root caries in this population.

Purpose of the Study:

  • To compare the efficacy of four different interventions in preventing new root caries among institutionalized elders.
  • To evaluate the long-term effectiveness of oral hygiene instruction (OHI), chlorhexidine varnish, sodium fluoride varnish, and silver diamine fluoride (SDF) in root caries prevention.

Main Methods:

  • A 3-year clinical trial involving 306 generally healthy elders from 21 residential homes.
  • Participants were randomly assigned to four groups: OHI alone, OHI with 1% chlorhexidine varnish (quarterly), OHI with 5% sodium fluoride varnish (quarterly), or OHI with 38% SDF solution (annually).

  • New root caries surfaces were assessed over the study period.

    • Main Results:

    • All evaluated interventions showed a statistically significant reduction in new root caries compared to OHI alone (ANOVA, p < 0.001).
    • The mean number of new root caries surfaces were 2.5 (OHI), 1.1 (chlorhexidine), 0.9 (sodium fluoride), and 0.7 (SDF).
    • Silver diamine fluoride (SDF) and sodium fluoride varnish demonstrated the highest effectiveness in preventing new root caries.

    Conclusions:

    • Quarterly applications of 1% chlorhexidine varnish, 5% sodium fluoride varnish, and annual applications of 38% SDF solution are effective methods for preventing root caries in institutionalized elders.
    • These professionally applied treatments offer superior protection against root caries compared to individualized oral hygiene instruction alone.
    • The findings support the integration of these preventive modalities into routine dental care for elderly populations residing in institutional settings.
