|February 1, 1986

Summary

Older adults, especially those in nursing homes, frequently develop root caries. Poor oral hygiene and medications causing dry mouth significantly predict root caries in this population.

Background:

Root caries is a significant oral health issue in older adults.
Factors influencing root caries in the elderly require further investigation.

Purpose of the Study:

To determine the association between overall health, medication use, oral hygiene, and root caries in older adults.
To identify key predictors of root caries in a geriatric population.

Main Methods:

Oral examinations and interviews were conducted on 47 older adults (24 community-dwelling, 23 nursing home residents).
The Oral Hygiene Index and Root Caries Index were utilized.
Data on overall health status and medication history were collected.

Main Results:

The majority of participants (42/47) exhibited root surface caries.
Mandibular teeth, particularly molars and premolars, were most affected.
Predictors of root caries included remaining teeth, calculus, plaque, and xerogenic medications.

Conclusions:

Older adults, particularly those in nursing homes, are at high risk for root caries.
Xerogenic medications are strongly associated with root caries, especially on maxillary teeth.
Interceptive dental care is crucial for high-risk geriatric populations, including those on multiple medications with poor oral hygiene.
