Association of severe early childhood caries with salivary ferritin

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.

Salivary elemental signature of dental caries: a systematic review and meta-analysis of ionomics studies

Trace- and macro-chemical elements are crucial for cellular physiological functioning, and their alterations in biological fluids might be associated with an underlying pathological state. Hence, this study aimed to examine and summarize the published literature concerning the application of salivary ionomics for caries diagnosis. An extensive search of studies was conducted using PubMed, EMBASE, Web of Science, and Scopus, without any language and year restriction for answering the following PECO question: "In subjects (i.e., children, adolescents, or adults) with good systematic health, are there any variations in the salivary concentrations of trace- or macro-elements between caries-free (CF) individuals and caries-active (CA) subjects?" A modified version of the QUADOMICS tool was used to assess the quality of the included studies. The Review Manager Version 5.4.1. was used for data analyses. The analysis of salivary chemical elements that significantly differed between CF and CA subjects was also performed. Thirty-four studies were included, involving 2299 CA and 1669 CF subjects, having an age range from 3 to 64 years in over 16 countries. The meta-analysis revealed a statistically significant difference (p < 0.05) in the salivary levels of calcium, phosphorus, chloride, magnesium, potassium, sodium, and zinc between CA and CF subjects, suggesting higher levels of calcium, phosphorus, potassium, and sodium in CF subjects while higher levels of chloride, magnesium, and zinc in CA patients. Half of the included studies (17/34) were considered high quality, while the remaining half were considered medium quality. Only zinc and chloride ions were found to be higher significantly and consistent in CF and CA subjects, respectively. Conflicting outcomes were observed for all other salivary chemical elements including aluminum, bromine, calcium, copper, fluoride, iron, potassium, magnesium, manganese, sodium, ammonia, nitrite, nitrate, phosphorus, lead, selenium, and sulfate ions.

Evaluation of Changes in Oral Microflora in Children with Early Childhood Caries after Full Mouth Rehabilitation

Aim

To evaluate the change in microflora in children suffering from severe early childhood caries (ECC) after full mouth rehabilitation.

Materials and methods

A total of 60 children, aged 3-5 years suffering from severe ECC who fulfilled the inclusion and exclusion criteria were included in the study. Pooled plaque samples were taken and subjected to quantitative reverse transcriptase polymerase chain reaction (PCR) to obtain baseline mean values of Streptococcus mutans (S. mutans), Streptococcus sobrinus (S. sobrinus), Candida albicans (C. albicans), and Candida dubliniensis (C. dubliniensis) before full mouth rehabilitation was done under general anesthesia. Posttreatment samples were collected at 6, 12, and 18 months. Wilcoxon signed-rank test was used to compare the mean values of S. mutans, S. sobrinus, C. albicans, and C. dubliniensis before and after full mouth rehabilitation.

Results

A total of 60 patients recruited for the study were present at the follow-up at 6 and 12 months. At 18 months, 55 patients returned, and five were lost due to follow-up. A statistically significant reduction was seen in all microorganisms at 6, 12, and 18 months compared to baseline values. At 18 months a slight increase in S. mutans, S. sobrinus, and C. albicans was seen. C. dubliniensis was not detected in any cases after full mouth rehabilitation. Caries recurrence was seen in four patients at 18 months.

Conclusion

Significant reduction of S. mutans, S. sobrinus, C. albicans, and C. dubliniensis was seen at 6, 12, and 18 months. A complete reduction of only C. dubliniensis was seen. A significant but not permanent reduction of S. mutans, S. sobrinus, and C. albicans. Caries recurrence was seen in 7.27% of patients at 18 months.

Evaluation of Factors Affecting Clinical Outcomes of Full Mouth Rehabilitation Under General Anaesthesia for Children With Early Childhood Caries: A Prospective Cohort Study

AIM

This study was designed to evaluate the factors affecting the clinical outcomes of full mouth rehabilitation under general anaesthesia for children with early childhood caries (ECCs).

MATERIALS AND METHODS

A prospective cohort of 200 children with early childhood caries and requiring dental rehabilitation under general anaesthesia was evaluated and treated. Children were recalled at six-month intervals for a period of two years and evaluated for the recurrence of caries and the need for repeat treatment of failed cases.

RESULTS

86.5% of the patients adhered to the six-month recall visits for 24 months. An overall caries recurrence rate of 14.5% was seen. Children who did not adhere to the follow-up plan and visited ad hoc had the highest caries recurrence rate (88%).

CONCLUSION

Good compliance with postoperative instructions after full mouth rehabilitation resulted in good oral hygiene and a limited recurrence of caries. Patients with poor compliance with recall visits and postoperative instructions had high rates of caries recurrence. Rehabilitation under general anaesthesia can be considered a viable treatment option for children diagnosed with early childhood caries.

Evaluation of Change in Quality of Life, Dental Fear and Dental Anxiety in Young Children Following Full-mouth Dental Rehabilitation under General Anesthesia for Early Childhood Caries

AIM

To evaluate the change in quality of life, dental fear, and dental anxiety in young children following full-mouth dental rehabilitation under general anesthesia for early childhood caries.

MATERIALS AND METHODS

About 200 children who were diagnosed with early childhood caries requiring full-mouth rehabilitation under general anesthesia were recruited after obtaining parental consent. Oral health-related quality of life (OHRQoL) was measured using the Early Childhood Oral Health Impact Scale (ECOHIS). Dental fear was evaluated using Children's Fear Survey Schedule-Dental Subscale and dental anxiety was evaluated using the Facial Image Scale. Scores were taken on the day of intervention, and after 14 days when the child reported for posttreatment follow-up.

RESULTS

All 200 participants returned for a follow-up visit after 2 weeks. The child impact section was reduced from 15.7 ± 4.1 to 7.7 ± 1.9 after treatment. The family impact section was reduced from 9.6 ± 2.7 to 3.5 ± 2.6 after treatment. A statistically significant difference was seen in both sections when pre-and posttreatment values were compared (p < 0.001). The total ECOHIS showed statistically significant improvement as the pretreatment score of 21.6 ± 9.5 reduced to 11.2 ± 4.2 showing 51.9% improvement in OHRQoL after full-mouth rehabilitation under general anesthesia was done (p < 0.001). Dental fear and anxiety among the participants showed a statistically significant reduction after treatment was done and most participants were found to be less fearful of doctors, dentists, and injections after treatment.

CONCLUSION

Full-mouth rehabilitation was found to be a reliable treatment modality to improve the OHRQoL of children suffering from early childhood caries.

CLINICAL SIGNIFICANCE

Significant improvement was seen in the OHRQoL within 2 weeks after treatment and most participants were found to be less anxious and fearful toward dentists and dental treatment. Comprehensive dental rehabilitation under general anesthesia has been proven to be an effective treatment modality for early childhood caries and a productive treatment technique to reduce dental fear and anxiety.

Evaluation of Factors Influencing the Oral Health-related Quality of Life among Children with Early Childhood Caries: A Cross-sectional Study

AIM

To evaluate the factors that affect the oral health-related quality of life (OHRQoL) among children with early childhood caries (ECC).

MATERIALS AND METHODS

A total of 340 children aged between 3 and 6 who were diagnosed with ECC were enrolled in the study. Parents accompanying the children completed a questionnaire on the sociodemographic status and filled out the Early Childhood Oral Health Impact Scale (ECOHIS) for the evaluation of OHRQoL. Data were recorded, tabulated, and statistically analyzed.

RESULTS

The study population consisted of 189 (55.6%) boys and 151 girls (44.4%). A total of 96.4% had cavitated lesions; 31.2% of the children had pain at the time of evaluation. A significant association was seen between the Decayed Missing Filled Teeth (DMFT) score of the child (p < 0.001). Pain at the time of evaluation and DMFT status had a significant association with the ECOHIS (p < 0.001).

CONCLUSION

Early childhood caries was found to impact the OHRQoL. Pain, visible dental plaque, family income, and parental education were found to be determinants that affect the OHRQoL.

CLINICAL SIGNIFICANCE

Early childhood caries significantly reduces the OHRQoL of children and their families. Pain, visible dental plaque, family income, and parental education were found to influence the OHRQoL. Teaching parents the importance of oral health and preventive treatment will help prevent the occurrence of ECC.

Parental and Child Outlook on the Impact of ECC on Oral Health-related Quality of Life: A Prospective Interventional Study

AIM

To evaluate the perspectives of parents and children on the impact of early childhood caries (ECC) on the oral health-related quality of life (OHQoF).

MATERIALS AND METHODS

About 400 children aged 3-5 years were recruited for the study. About 200 children who were caries-free were the controls for the study. The remaining 200 consisted of children who were diagnosed with ECC and required dental rehabilitation under general anesthesia. Oral health-related quality of life was recorded at baseline and 6 months after intervention using the Michigan oral health-related quality of life scale. Data were analyzed and evaluated using Statistical Package for Social Sciences (SPSS) Version 25.0.

RESULTS

Children with ECC were found to have a significantly lower oral health-related quality of life compared with caries-free children, and a statistically significant difference was seen between both groups. The main concern for both parents and children at baseline was pain at the first visit when the evaluation was done. After the intervention, a significant improvement in the oral health-related quality of life was seen.

CONCLUSION

Early childhood caries was found to have detrimental effects on the oral health-related quality of life. Full-mouth rehabilitation under general anesthesia was found to bring a significant improvement in the oral health-related quality of life. The perspectives of both parents and children were found to be similar.

CLINICAL SIGNIFICANCE

Early childhood caries has an impact on the lives of children and their parents. Oral health-related quality of life was low with children suffering from ECC. Full-mouth rehabilitation under general anesthesia can significantly improve the OHRQoL of children. Continuous monitoring of the children with regular follow-ups and parental education should be enforced to prevent the relapse of ECC.

Evaluation of Serum and Salivary Iron and Ferritin Levels in Children with Dental Caries: A Meta-Analysis and Trial Sequential Analysis

Background and objective: Dental caries appears to be related to iron deficiency anemia and to low ferritin levels. In the present meta-analysis, we report salivary and serum iron and ferritin levels in children with dental caries, compared to healthy controls. Materials and methods: We searched in Web of Science, Cochrane Library, Scopus, and PubMed/Medline databases to extract studies published until 25 July 2021. We calculated mean differences (MD) and 95% confidence intervals (CI) of salivary and serum iron and ferritin levels in children with dental caries, always compared to healthy controls. In addition, we applied a trial sequential analysis (TSA). Results: A total of twelve articles covering thirteen studies were included in the meta-analysis. The pooled MD for salivary iron level was −5.76 µg/dL (p = 0.57), and −27.70 µg/dL (p < 0.00001) for serum iron level: compared to healthy controls, children with dental caries did not show different salivary iron levels, while children with caries had significantly lower serum iron levels. The pooled MD of salivary ferritin level was 34.84 µg/dL (p = 0.28), and the pooled MD of serum ferritin level was −8.95 µg/L (p = 0.04): compared to healthy controls, children with dental caries did not have different salivary iron levels, but significantly lower serum ferritin levels. Conclusions: The findings of the present meta-analysis showed that salivary levels of iron and ferritin did not differ between children with and without caries, though compared to healthy controls, children with caries had significantly lower salivary and serum iron and ferritin levels. The results are of practical and clinical importance: Possibly, iron and ferritin supplementation might prevent or attenuate dental caries in children at risk. Further, children with caries might suffer from further iron- and ferritin-related health issues. Lastly, serum blood samples, but not saliva samples inform accurately about the current iron and ferritin concentrations in children with or without caries.
