Periodontal disease and leucopenia

Area of Science:

• Veterinary Medicine
• Comparative Pathology
• Animal Dentistry

Background:

• Periodontal disease is prevalent in domestic dogs and cats, unlike in wild animals.
• Unnatural diets contribute to oral microbial imbalances, triggering host immune responses and periodontitis.
• Existing hematological reference ranges may not account for subclinical periodontal disease.

Purpose of the Study:

• To investigate the relationship between periodontal disease and leucocyte counts in domestic animals.
• To assess the impact of dietary changes and dental treatment on leucocyte levels.
• To question the validity of current hematological reference ranges in the context of periodontal disease.

Main Methods:

• Eight of fourteen animals with periodontal disease underwent dental treatment and dietary modification.
• Leucocyte counts were measured before and after intervention.
• Subjective health assessments were recorded concurrently.

Main Results:

• Initial leucocyte counts were low in the investigated animals.
• Follow-up testing showed an average increase of 77.7% in leucocyte counts.
• The increase in leucocyte counts correlated with subjective improvements in animal health.

Conclusions:

• Low leucocyte counts in domestic animals may be linked to periodontal disease.
• Dietary changes and dental treatment can reverse leucocyte depression.
• Further research is warranted to refine hematological reference ranges for animals with periodontal disease.
