Relationship between decrease of erythrocyte count and progression of periodontal disease in a rural Japanese...

Area of Science:

• Oral health research
• Hematology
• Public health

Background:

• Limited research exists on the connection between periodontal status and erythrocyte parameters.
• This study utilizes longitudinal health checkup data to explore this relationship.

Purpose of the Study:

• To clarify the association between periodontal disease progression and changes in erythrocyte parameters.
• To investigate potential links between oral health and blood cell counts.

Main Methods:

• A prospective study involving 120 subjects (30 men, 85 women) aged 30-63.
• Data collected from health and dental checkups in 2006 and 2007, including medical and oral examinations.
• Periodontal disease progression defined by attachment loss or tooth loss; statistical analyses included Wilcoxon signed-rank, chi-squared, Fisher exact, Mann-Whitney U tests, and logistic regression.

Main Results:

• The progression group included 30 subjects.
• Significant differences were found in erythrocyte count changes between progression and non-progression groups.
• Periodontal disease progression was associated with a decrease in erythrocyte counts (adjusted odds ratio = 0.970; P = 0.009).

Conclusions:

• Periodontal disease progression is associated with a decrease in erythrocyte counts.
• Findings suggest a link between oral health status and red blood cell parameters in a rural Japanese population.
