The association of body mass index and severe early childhood caries in young children in Winnipeg, Manitoba: A cross-sectional study

Early Childhood Caries and Nutritional Status of Children: A Review

BACKGROUND

Early childhood caries (ECC) is a serious public health issue affecting children around the world. Severe symptoms and complications commonly found with ECC are adverse effects on health and growth retardation triggered by sensitivity, pain, and abscesses associated with decayed teeth, premature tooth loss, and insufficient food intake due to difficulty in chewing and keeping food in the mouth.

OBJECTIVE

This article aims to provide an overview of the most recent and current evidence on the association between ECC and nutritional status with an aim to stimulate further research and to identify the impact of nutritional status on ECC and vice versa.

METHODS

PubMed, Web of Science, and Google Scholar databases were used to search the studies conducted between 2016 and 2022. The included studies were searched using some keyword combinations and saved in Mendeley Desktop for review and referencing. All books, policy briefs, thesis/dissertations, and non-peer-reviewed articles were excluded, and 47 studies were selected for this narrative review.

RESULTS

Many studies have identified long-term, frequent, and nocturnal bottle-feeding and breastfeeding as well as frequent consumption of sugary food and beverages as high-risk factors for ECC. Adverse nutritional status assessed by anthropometric measures, vitamin D status, and iron-deficiency anemia have been studied as risk factors for ECC.

CONCLUSIONS

Most of the prevailing studies are either case-control or cross-sectional studies, which are unable to provide strong evidence to prove the direction of causality. Thus, further prospective studies are needed to clarify the association between ECC and the nutritional status of children.

Comprehensive Dental Treatment under General Anesthesia Improves Mastication Capability in Children with Early Childhood Caries-A One-Year Follow-Up Study

BACKGROUND

Using the granulometry of ready-to-swallow food boluses, this study investigated the evolution of masticatory capability of children with Early Childhood Caries (ECC) after comprehensive dental treatment under general anesthesia (GA).

METHODS

Sixteen children with ECC were assessed before and over one year after dental treatment under GA, in comparison with 12 children with a Healthy Oral State (HOS). Oral health criteria, quality of life, body mass index, and frequency of orofacial dysfunctions were recorded. Masticatory kinematic parameters and median food bolus particle size (D50) at swallowing were assessed while masticating raw carrot (CAR), cheese (CHS), and breakfast cereals (CER). The impact of posterior teeth extractions was analyzed.

RESULTS

Quality of life and orofacial functions improved after dental treatment. Chewing frequency for all three foods increased without reaching the values of children with HOS, while D50 values for CAR and CHS decreased. After one year, children with posterior teeth extractions exhibited higher D50 values for CAR and CHS than children with only conservative treatment. One third of children with ECC were overweight or obese.

CONCLUSIONS

Comprehensive dental treatment improved children's mastication, and their BMI subsequently increased. Links between mastication and nutrition should be investigated further in children.

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.

Early childhood caries, obesity and anthropometric measurements: Is there a relationship?

This brief research report explored the relationship among obesity, anthropometric measurements, and early childhood caries (ECC), in 3–5 years-old children. Three hundred and ninety-one Brazilian preschoolers were given anthropometric examinations for the assessment of general, peripheral, and central adiposity, by the following measures: body mass index (BMI), hip circumference, and waist circumference. Obesity status was determined by BMI according to WHO standards. Parent's age and BMI were assessed by questionnaire, and sucrose exposure was tracked by means of a food diary. For the assessment of ECC, dental examinations were performed according to modified WHO criteria. Also, the presence of dental biofilm in maxillary incisors was detected. A direct association between BMI and ECC was found in the bivariate analysis and the best possibility of logistic regression model showed that hip circumference (HC) values ≥62 centimeters (OR = 1.63; p = 0.033) jointly with the presence of dental biofilm (OR = 2.38; p = 0.000), children's ages ≥37 months (OR = 5.09; p = 0.012), and mothers younger than 35 years (OR = 1.96; p = 0.004) were significantly connected with ECC. In conclusion, peripheral adiposity (represented by HC) in young children was in fact associated with ECC. Thus, hip circumference might be a valuable tool for exploring the relationship between caries and obesity in the early years of life.

The Association between Nutritional Alterations and Oral Lesions in a Pediatric Population: An Epidemiological Study

The oral conditions of an individual are the result of different factors, including the subject's genotype, oral hygiene habits, the type of diet, and lifestyle, such as smoking. Nutrition in the first years of life can affect dental health for a long time. To prevent mouth diseases, it is also important to eliminate unfavorable eating behaviour and to amplify protective ones. Eating habits, especially in pediatric age, are an easily modifiable and controllable factor, and diet, in addition to influencing the health of the oral cavity, plays a fundamental role in systemic health. Indeed, a sugar-rich diet can lead to conditions, such as diabetes, being overweight, and obesity. The present research was an epidemiological study, with the aim of highlighting some of the associations between nutrition and oral health. In particular, we studied those lesions of hard and soft tissues that are diagnosed most frequently by dentists: caries, enamel hypoplasia, periodontal disease, and aphotoxic lesions and their associations with nutritional deficiencies and excesses including proteins, vitamin A, vitamin D, B vitamins, and iron and calcium minerals. To perform this study, we recruited 70 patients from the pediatric and orthodontic clinics, aged between 3 and 15 years (y), with mean age of 10.4 y.o. The study was conducted by providing a questionnaire to pediatric patients' (supported from their parents or guardians) on individual eating habits, followed by an accurate oral cavity specialistic examination. The nutritional data were processed by using Grana Padano Observatory (OGP) software, freely provided online by the OPG. The statistical tests performed were the chi-square (χ²) for independence, and Cramér's V test was used to evaluate the associations between eating habits and oral pathologies. The results showed that certain nutritional vitamin deficiencies and nutritional excesses were associated with definite oral pathologies.

Associations between dental caries and systemic diseases: a scoping review

BACKGROUND

The objective of this study was to evaluate and present evidence from animal and human clinical studies on associations between dental caries and systemic diseases, and to suggest potential mechanisms that might explain such associations.

METHODS

An electronic search was conducted of PubMed, Embase and Cochrane Central Register of Controlled Trials for articles published from 2010 to 2020 in the English language. From the initial search, 404 full-text studies were assessed for eligibility. After excluding studies for technical and study limitations, a total of 67 studies were included in the summary tables and additional studies were included in the review to support evidence.

RESULTS

Few systemic disease and conditions were found to be clinically meaningfully associated with caries experience. Best evidence from human and animal studies described association between metabolic diseases and dental caries. Several interesting animal studies were noted that could generate clinical hypotheses and further investigations in rodent models for cardiovascular injury and hyperglycemia. Inadequate data was found to suggest any modifications to current clinical practice or prevention guidelines.

CONCLUSIONS

Limited clinical evidence was found connecting several systemic diseases and dental caries. Inadequate data was found to suggest any modifications to current clinical practice or prevention guidelines.

CLINICAL SIGNIFICANCE

Understanding of associations between dental caries and systemic diseases play a crucial role in the treatment planning and education of the dental patient.

Association between nutritional status and early childhood caries risk profile in a suburban Nigeria community

BACKGROUND

Malnutrition is associated with oral health problems.

AIM

To determine the association between malnutrition (undernourished and over-nourished) and early childhood caries (ECC) in a suburban population in Nigeria.

DESIGN

Data were extracted from a database of a household survey of 1549 under 6-year-old children. Explanatory variables were nutritional status (normal, undernourished [wasted, stunted and underweight], or over-nourished). The outcome measure was the prevalence of ECC. Children's sociodemographic characteristics (socio-economic status, sex, age) and caries-risk variables (frequency of sugar consumption in-between-meals, oral hygiene status) were the confounders. Association between ECC and malnutrition was determined using the Poisson regression analysis. Statistical significance was set at P ≤ .05.

RESULTS

About one-third (31.4%) of children had expected height/weight for age; 848 (54.7%) were undernourished; and 215 (13.9%) were over-nourished. Nutritional status was not significantly associated with the prevalence of ECC. Children who consumed sugar in-between-meals three or more times a day were twice as likely to have ECC as were those who consumed sugar less often in-between-meals (APR: 2.23; 95% CI: 1.30-3.81; P = .003). Children 3-5 years old were more likely to have ECC than were those 0-2 years old (APR: 2.40; 95% CI: 1.10-5.22; P = .03).

CONCLUSIONS

ECC was not associated with undernourished and over-nourished in a suburban population in Nigeria.

Association between early childhood oral health impact scale (ECOHIS) scores and pediatric dental surgery wait times

BACKGROUND

Severe Early Childhood Caries (S-ECC) is an aggressive form of tooth decay that often requires pediatric dental rehabilitative surgery. The Early Childhood Oral Health Impact Scale (ECOHIS) measures oral health-related quality of life (OHRQL). The purpose of this study was to determine whether there is an association between ECOHIS scores and surgery wait times for children undergoing dental treatment for S-ECC under general anesthesia (GA).

METHODS

The hypothesis was that there is no present association between wait times and ECOHIS score. Children under 72 months of age with S-ECC were recruited on the day of their slated dental surgery under GA. Parents/caregivers completed a questionnaire that included the ECOHIS. Data were merged with other ECOHIS scores from a previous study. Wait times were acquired from the Patient Access Registry Tool (PART) database. Data analysis included descriptive statistics and bivariate analyses. A p-value of ≤0.05 was considered statistically significant; 95% confidence intervals (CIs) were reported for each correlation coefficient. This study was approved by the University of Manitoba's Health Research Ethics Board.

RESULTS

Overall, 200 children participated, the majority of whom were Indigenous (63%) and resided in Winnipeg (52.5%). The mean age was 47.6 ± 13.8 months and 50.5% were female. Analyses showed ECOHIS scores were not significantly correlated with children's wait times. Observed correlations between ECOHIS and children's wait times were low and not statistically significant, ranging from ρ = 0.11 for wait times and child impact section (CIS) scores (95% CI: - 0.04, 0.26; p = 0.14), ρ = - 0.08 for family impact section (FIS) scores (95% CI: - 0.23, 0.07; p = 0.28), and ρ = 0.04 for total ECOHIS scores (95% CI: - 0.11, 0.19; p = 0.56).

CONCLUSION

No significant associations were observed between ECOHIS scores and wait times. In fact, those with worse OHRQL appeared to wait longer for surgery. ECOHIS scores could, however, still be used to help prioritize children for dental surgery to ensure that they receive timely access to dental care under GA. This is essential given the challenges posed by COVID-19 on timely access to surgical care.
