The association between dmft index and haemoglobin levels in 3–6 year-old Saudi children with anaemia: A cross sectional study

ObjectivesThe relation between haemoglobin levels and the prevalence of dental caries is well-recognized; however, relatively little information is available regarding the decayed, missing and filled teeth (dmft) index in relation to haemoglobin levels in KSA. The objective of this study was to assess the association between the haemoglobin levels and the dmft index in a random sample of paediatric dental patients who visit a teaching hospital in KSA.MethodsThis 11-month cross sectional study was conducted at King Abdulaziz University Hospital, Jeddah, KSA from May 2014 to April 2015. A total of 160 children with dental caries were divided into 2 groups: non-anaemic and anaemic groups. The prevalence of caries was measured using the dmft index and was compared between the two groups. Statistical analyses were performed using the chi-square tests at a 0.05% significance level.ResultsOne hundred-sixty subjects were recruited in this study. Children with lower mean haemoglobin levels (anaemic children) had significantly higher mean dmft indices (11.20 ± 2.6) than the non-anaemic children (9.66 ± 1.2%, p < 0.05).ConclusionThis study suggests that children with lower haemoglobin levels may be prone to develop dental caries. This study emphasizes the need for public health campaigns regarding oral hygiene and the prevention and treatment of anaemia.
