Relationship between periodontitis and hepatic abnormalities in young adults

Area of Science:

• Oral Health
• Hepatology
• Public Health

Background:

• Obesity is linked to periodontitis and non-alcoholic fatty liver disease (NAFLD).
• Elevated alanine aminotransferase (ALT) is a marker for NAFLD in obese individuals.
• The relationship between liver function and periodontitis in young adults is not well-established.

Purpose of the Study:

• To investigate the association between ALT levels and periodontitis in young Japanese university students.
• To explore potential early indicators of periodontitis in a young adult population.
• To determine if liver health markers correlate with oral health status in this demographic.

Main Methods:

• Cross-sectional study of 2225 healthy, non-smoking university students aged 18-19 in Japan.
• Periodontitis defined as probing pocket depth ≥ 4 mm, following US National Health and Nutrition Examination Survey protocols.
• Logistic regression analysis used to assess the association between ALT, BMI, and periodontitis.

Main Results:

• 104 students (4.7%) had periodontitis.
• In males, periodontitis was significantly associated with elevated ALT levels (≥ 41 IU/l) (adjusted OR 2.3, p < 0.05).
• No significant association was found between periodontitis and ALT in female students.

Conclusions:

• Elevated ALT may serve as a potential risk indicator for periodontitis in young adult males.
• Further research is needed to understand the monitoring of hepatic abnormalities for periodontitis prevention in young populations.
• This study highlights a potential link between liver health and oral health in young men.
