Exploratory study on the association between oral functions and nailfold capillary parameters.

Area of Science:

• Gerontology
• Oral Medicine
• Microcirculation

Background:

• Extending life expectancy is a key public health goal.
• Oral frailty is linked to overall systemic health.
• The connection between oral function and nailfold capillary parameters is not well understood.

Purpose of the Study:

• To investigate the association between oral function parameters and nailfold capillary characteristics.
• To explore potential links between oral health and microvascular changes.

Main Methods:

• Analysis of data from 311 participants (mean age 55.66 years).
• Evaluation of oral parameters: number of remaining teeth, tongue pressure, and oral mucosal moisture.
• Assessment of nailfold capillary parameters: number, length, width, and turbidity.

Main Results:

• A significant association was observed between the number of remaining teeth and capillary number.
• Oral mucosal moisture showed significant associations with capillary turbidity and width.
• These associations were not statistically significant after P-value adjustment and are considered preliminary.

Conclusions:

• Findings suggest potential links between specific oral functions and nailfold capillary parameters.
• These results provide a basis for hypothesis-generating research on oral-systemic health connections.
• Further investigation into oral health's role in systemic conditions and potential diagnostic applications is warranted.
