The prevalence of iron deficiency anemia in children with severe early childhood caries undergoing dental surgery under general anesthesia

Iron Deficiency Anemia and Its Impact on Oral Health-A Literature Review

Oral disease interventions primarily focus on behavioral changes like dietary improvements and ensuring better oral hygiene. However, recognizing the influence of biological factors, including genetics and early-life nutrition, is crucial. Iron deficiency (ID) and its advanced form, iron deficiency anemia (IDA), affect nearly two billion people globally, especially children and pregnant women. We conducted a comprehensive search using Medline via EndNote and Web of Science, employing keywords related to iron deficiency anemia (IDA), and we identified 36 studies deemed relevant for inclusion in this literature review. IDA prevalence is notably high among pregnant women and young children. Both IDA and early-childhood caries (ECC) disproportionately affect impoverished populations, highlighting the socioeconomic dimension of this issue. IDA presents with various oral mucosal changes and is closely linked to candidiasis. Additionally, IDA can hinder tooth development and weaken the immune response. Multiple population surveys have revealed a significant association between ECC and IDA. While some studies have explored the IDA-periodontal disease link, the current evidence is relatively limited in its robustness. In conclusion, more comprehensive longitudinal studies are essential to deepen our understanding of the IDA-oral disease connection. Investigating the underlying biological mechanisms is critical to developing effective interventions, particularly for vulnerable populations affected by IDA.

Is there an association between early childhood caries and iron deficiency anaemia?

Clinical question To determine the association between early childhood caries (ECC) and iron deficiency anaemia (IDA).Data sources A systematic search was carried out in seven databases by two independent reviewers. Also, manual searching and grey literature screening were carried out.Study selection Cross-sectional, case-control and cohort studies that evaluated the association between ECC and IDA were included. Only publications in the English language were considered for study eligibility.Data extraction and synthesis The characteristics of the included studies - age, sex, sample size, diagnostic methods used, index used for ECC, blood parameters, odds ration/risk ratio, confidence interval, p value, outcomes and assessment of any confounders - were extracted from the included papers. The quality assessment for case-control and cohort studies was performed according to the Newcastle-Ottawa assessment scale, while the modified Newcastle-Ottawa assessment scale was used for the cross-sectional studies.Results A total of 14 publications were included for qualitative review and seven of them were included in the meta-analysis. Children affected by ECC had an increased likelihood of IDA when compared to those not affected by ECC. However, the meta-analysis showed no statistical difference in blood parameters (haemoglobin, mean corpuscular volume and serum ferritin) in children with and without ECC.Conclusions There is an association between ECC and increased odds of IDA; however, there is a lack of scientific evidence to determine a cause and effect relation or direction of association between ECC and IDA.

A Novel Expert System for Diagnosis of Iron Deficiency Anemia

Diagnosis of a disease is one of the most important processes in the field of medicine. Thus, computer-aided detection systems are becoming increasingly important to assist physicians. The iron deficiency anemia (IDA) is a serious health problem that requires careful diagnosis. Diagnosis of IDA is a classification problem, and there are various studies conducted. Researchers also use feature selection approaches to detect significant variables. Studies so far investigate different classification problems such as outliers, class imbalance, presence of noise, and multicollinearity. However, datasets are usually affected by more than one of these problems. In this study, we aimed to create multiple systems that can separate diseased and healthy individuals and detect the variables that have a significant effect on these diseases considering influential classification problems. For this, we prepared different datasets based on the original dataset whose outliers were removed using different outlier detection methods. Then, a multistep classification algorithm was proposed for each dataset to see the results under irregular and regulated conditions. In each step, a different classification problem is handled. The results showed that it is important to consider each question together as it can and should change the outcome. Dataset and R codes used in the study are available as supplementary files online.

Early Childhood Caries and Iron Deficiency Anaemia: A Systematic Review and Meta-Analysis

Identification of the association between Early Childhood Caries (ECC) and Iron Deficiency Anaemia (IDA) will aid paediatricians and paediatric dentists to enhance health promotion measures to reduce the related morbidity in children. This systematic review aims to determine an evidence-based association between ECC and IDA. A systematic search was carried out from MEDLINE via PubMed, EMBASE, LILACS, Cochrane Oral Health Group's Specialized Register, CINAHL via EBSCO, Web of Science, and Scopus up to May 2020. Hand searching and grey literature screening were also conducted. Cross-sectional, case-control, and cohort studies in English language which assessed the association was included. Two reviewers independently assessed the study quality and extracted the outcome data. A total of 1,434 studies were identified. Fourteen studies qualified for qualitative review and 7 of them for a meta-analysis. In comparison with children not affected by ECC, those affected had an increased likelihood of IDA (OR = 6.07 [3.61, 10.21]). The meta-analysis showed no statistical difference when comparing blood parameters (Hb, MCV, and serum ferritin) in children with and without ECC. This systematic review demonstrates an association between ECC and increased odds of IDA rather than it being the cause for IDA. Further longitudinal studies with robust methodology are required to determine an evidence-based association.
