Correlation between caries and hemoglobin level among primary school children suffering from iron deficiency anemia

Background Iron deficiency anemia (IDA) is a severe health problem that affects over two billion people worldwide. Data has shown that IDA is intrinsically related to dental caries. However, few studies have been performed on their relationship. Our study aimed to assess the correlation between a caries index score and hemoglobin (Hb) level in primary school students in the age group 6-12 years.

Methods A cross-sectional study was done. A sample of forty patients; suffering from IDA; was selected from three pediatric outpatient clinics by simple random technique and interviewed with a final questionnaire.

Results Our findings concluded that there was a significant moderate negative correlation between caries index score and Hb level (r=-0.475, p=0.0019). There was a statistically significant Hb level mean difference between the high and low caries index groups. There was also a significant moderate negative correlation between caries index score and age, and height. Parameters predicting caries index score were identified as Hb level and frequency of sugar intake.

Conclusions In conclusion, patients of three pediatric outpatient clinics have a significant moderate negative correlation between caries index score and Hb level and need implementation of proper dental screening and preventive programs.
