Evaluation of the relation between anemia and periodontitis by estimation of blood parameters: A cross-sectional study.

BACKGROUND

Anemia of chronic disease is defined as anemia occurring in chronic infections, inflammatory conditions, or neoplastic disorders which are not due to marrow deficiencies or other diseases, and occurring despite the presence of adequate iron stores and vitamins.

AIMS

To evaluate the relation between anemia and periodontitis by estimation of blood parameters and to assess whether periodontitis like other inflammatory conditions can lead to anemia. It is a randomized controlled clinical trial.

MATERIALS AND METHODS

A total of 50 healthy controls, 50 chronic generalized gingivitis, and 50 chronic generalized periodontitis patients were selected. Hemoglobin levels (Hb), erythrocyte count red blood cell, erythrocyte sedimentation rate (ESR), mean corpuscular volu e (MCV), mean corpuscular Hb (MCH) and MCH concentration (MCHC), gingival index, plaque index, probing pocket depth, and clinical attachment level were recorded. Intergroup comparison of blood parameters is by one-way ANOVA. Intergroup pair wise comparison of the three groups is by Newman-Keuls multiple post-hoc procedures. Karl Pearsons's correlation coefficient method is used for correlation between different parameters for three groups.

RESULTS

The results revealed a decrease in Hb and erythrocyte counts and increase in white blood corpuscles counts in chronic generalized periodontitis when compared to healthy controls and chronic generalized gingivitis group. There was no statistically significant difference in MCV, MCH, MCHC, and ESR among the groups.

CONCLUSIONS

The treatment of periodontitis can lead to an improvement in hematocrit and other related blood parameters in chronic generalized periodontitis patients with anemia. This provides evidence that periodontitis like other chronic diseases may also cause anemia.
