Dexterity testing as a predictor of oral care ability

Area of Science:

• Gerontology
• Oral Health
• Rehabilitation Science

Background:

• Oral hygiene is crucial for overall health in the elderly.
• Assessing oral care ability in older adults is challenging.
• Dexterity and hand function may impact self-care capabilities.

Purpose of the Study:

• To determine if hand function and dexterity measures can predict oral care ability in elderly individuals.
• To investigate the relationship between fine motor skills and oral hygiene effectiveness.
• To identify potential screening tools for oral self-care deficits in the aging population.

Main Methods:

• A study involving 52 elderly participants (mean age not specified, predominantly male) from a VA medical center and a nursing home.
• Blinded examiners assessed dental plaque scores (Turesky modification of Quigley-Hein index) as the primary outcome.
• Evaluated participants using various dexterity tests (Jebsen-Taylor Hand Function, Nine-hole Peg, Box and Block, Toothbrushing Ability), grip strength, and cognitive function (Allen Cognitive Level Test).

Main Results:

• Institutionalized elderly individuals exhibited significantly poorer oral hygiene and dexterity compared to outpatients (P < 0.001).
• All assessed dexterity tests showed a significant correlation with plaque scores (Spearman rho: 0.49-0.77; P < 0.000).
• The Toothbrushing Ability Test and time spent brushing were the strongest predictors of plaque score (P < 0.0001 and P = 0.007, respectively).

Conclusions:

• Oral hygiene ability is notably reduced in long-term care residents.
• Dexterity tests are effective in identifying elderly patients with inadequate oral self-care.
• These tests can serve as valuable tools for estimating brushing efficacy in compromised older adults.
