The association of maternal folic acid supplementation and prenatal folate and vitamin B12 concentrations with child dental development

Dental complications in homocystinurias

Background

Cystathionine beta synthase deficiency (causing classical homocystinuria) has been associated with high-arched palates and crowded teeth, but little has been said about other oral health complications. Other homocystinurias (e.g., the remethylation defects) also have had little reported in terms of oral health. Individuals with the homocystinurias have been described as having bone density issues which can correlate with oral health. Moreover, elevations in homocysteine have a theoretical impact on tooth health and the paucity of clinical reports of oral health issues in homocystinuria may be the consequence of lack of attention by the medical community.

Significance

Oral health is essential to overall health. If inadequate attention is paid to the oral health complications which can be seen in homocystinurias, then appropriate referrals and attention in therapeutic guidelines will not reflect the importance of oral health.

Specific aims/research question

What oral health complications are reported by individuals with homocystinurias? Do these differ according to diagnosis?

Methods

Data were collected from patients with homocystinurias by a series of questionnaires using the RARE-X platform. All subjects were consented prior to the collection of their data. All research was performed in accordance with the Declaration of Helsinki. Demographic data were collected as the initial questionnaire and other data were collected via the oral health questionnaire.

Analysis

Questionnaires were opened to the community in mid-2022 and collection of data for this study ended with data submitted up to November 2022. Descriptive statistics were done. Due to the small size of the cohort, additional statistical analyses were not attempted.

Results

Patients with homocystinuria, not related to cystathionine beta synthase deficiency, are reporting some tooth structure differences. The cohort taken as a whole does not have increased risk for gingivitis, but there appears to be a risk for long-term gum disease possibly due to the rate of osteoporosis/osteopenia in this population. A large number of individuals have malalignment and malocclusion of the teeth. These data highlight oral health as an important component of care in individuals with the homocystinurias as is true of the general population at large.

Oral and craniofacial research in the Generation R study: an executive summary

OBJECTIVES

Oral conditions are of high prevalence and chronic character within the general population. Identifying the risk factors and determinants of oral disease is important, not only to reduce the burden of oral diseases, but also to improve (equal access to) oral health care systems, and to develop effective oral health promotion programs. Longitudinal population-based (birth-)cohort studies are very suitable to study risk factors on common oral diseases and have the potential to emphasize the importance of a healthy start for oral health. In this paper, we provide an overview of the comprehensive oral and craniofacial dataset that has been collected in the Generation R study: a population-based prospective birth cohort in the Netherlands that was designed to identify causes of health from fetal life until adulthood.

METHODS

Within the multidisciplinary context of the Generation R study, oral and craniofacial data has been collected from the age of 3 years onwards, and continued at the age of six, nine, and thirteen. Data collection is continuing in 17-year-old participants.

RESEARCH OUTCOMES

In total, the cohort population comprised 9749 children at birth, and 7405 eligible participants at the age of seventeen. Based on questionnaires, the dataset contains information on oral hygiene, dental visits, oral habits, oral health-related quality of life, orthodontic treatment, and obstructive sleep apnea. Based on direct measurements, the dataset contains information on dental caries, developmental defects of enamel, objective orthodontic treatment need, dental development, craniofacial characteristics, mandibular cortical thickness, and 3D facial measurements.

CONCLUSIONS

Several research lines have been set up using the oral and craniofacial data linked with the extensive data collection that exists within the Generation R study.

CLINICAL RELEVANCE

Being embedded in a multidisciplinary and longitudinal birth cohort study allows researchers to study several determinants of oral and craniofacial health, and to provide answers and insight into unknown etiologies and oral health problems in the general population.

Role of nutritional supplements on oral health in adults - A systematic review

Purpose: The word 'diet' usually encompasses the consumption of food that includes all the necessary nutrients required for the optimal functioning of the body. Nutritional supplements hold a supreme position due to the demanding lifestyles or medical conditions in this current era. Although medical literature has sufficient evidence exploring the effect of nutrients on general health, this systematic review aimed at specifically evaluating the role of nutritional supplements on oral health in adults. Methods: PRISMA guidelines were followed in conducting this systematic review where four electronic databases including Scopus, PubMed, EMBASE, and Web of Science were reviewed. Based on the inclusion criteria, four studies exploring the effect of oral nutritional supplements on oral health among the adult population were included in this systematic review. Results: This review generated evidence suggesting a positive effect of nutritional supplements on oral health. These findings were depicted in the form of a reduction in plaque scores, probing depths, gingival inflammation, and greater improvement in periodontal healing among individuals with higher intakes of nutritional supplements within recommended doses. Conclusions: The systematic review outlines the positive impact of consuming nutritional supplements in the recommended dosage on oral health. Additionally, this review stresses the necessity for interventional studies to further investigate the effects of nutritional supplements on oral health, particularly in regard to periodontal healing.
