Association between Vitamin D and Dental Caries in a Sample of Canadian and American Preschool-Aged Children. Nutrients 2021; 13:nu13124465. [PMID: 34960016 PMCID: PMC8706858 DOI: 10.3390/nu13124465] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Revised: 12/11/2021] [Accepted: 12/12/2021] [Indexed: 12/26/2022] Open
Abstract
Background: Inadequate vitamin D levels may increase the risk of caries during childhood. The purpose of this study was to investigate the association between 25-hydroxyvitamin D (25(OH)D) status and severe early childhood caries (S-ECC) in preschool children. Methods: Data were obtained from children <72 months of age in two case–control studies in Winnipeg, Manitoba and Richmond, Virginia. Serum analysis assessed 25(OH)D, calcium and parathyroid concentrations. Data on demographics, dental history and oral hygiene were obtained via questionnaires. Bivariate and multiple logistic regression analyses were performed to assess the relationships between demographic and biological variables and S-ECC. A p-value of ≤0.05 was significant. Results: Data were available for 200 children with S-ECC and 144 caries-free controls. Children with S-ECC had significantly lower 25(OH)D levels than those who were caries-free (p < 0.001), and children with deficient 25(OH)D levels were 10 times more likely to have S-ECC (p < 0.001). Multiple logistic regression revealed that having higher 25(OH)D and calcium concentrations (p = 0.019 and p < 0.0001, respectively), as well as being breastfed in infancy (p < 0.001), were significantly and independently associated with lower odds of S-ECC, while dental insurance (p = 0.006) was associated with higher odds of S-ECC. Conclusions: This study provides additional evidence of an association between nutritional status, specifically vitamin D and calcium levels, and S-ECC.

Clin Oral Investig 2021; 25:6147-6158. [PMID: 33834312 PMCID: PMC8531070 DOI: 10.1007/s00784-021-03914-8] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Accepted: 03/25/2021] [Indexed: 12/31/2022]
Abstract
OBJECTIVE The study aimed to assess the association between parental-reported vitamin D supplementation and caries in a national sample of 3-year-olds in Poland. MATERIALS AND METHODS A total of 1900 children, representing all provinces of Poland, were invited. The questionnaires concerned vitamin D supplementation, socio-demographics, and oral health behaviours. Based on dental examination, caries scores (dmft/dmfs), prevalence of early childhood caries (ECC) and severe ECC (S-ECC) were calculated. The Spearman's correlation, linear regression and logistic regression were used to assess the association between various factors and caries (p < 0.05). RESULTS A total of 1638 children were tested. Of this number, 99.1% infants were supplemented with vitamin D. Supplementation had been continued seasonally in 55.2% children. ECC/S-ECC prevalence were significantly lower in children receiving vitamin D (ECC 38.3% vs. 44.7%, OR = 0.77; S-ECC 20.5% vs. 27.1%, OR = 0.69; p < 0.05). Mean dmft/dmfs were lower in those with supplementation (1.54 ± 2.72 vs. 2.24 ± 3.55; 2.40 ± 5.56 vs. 3.72 ± 7.56, respectively; p < 0.001). After controlling for confounding factors, supplementation was not significantly associated with caries; only dt/ds were still associated. Maternal education, sweetened beverages before bedtime, bottle use were significantly associated with S-ECC. CONCLUSIONS Lower caries prevalence was observed in those with vitamin D supplementation. The association between parental-reported vitamin D and ECC/S-ECC was not significant in Polish children. Decayed teeth and supplementation were still associated. Dietary habits can modify the association with caries. CLINICAL RELEVANCE There may be an association between vitamin D supplementation and lower caries in children. Parents should supplement their children during periods of significant growth and development.

Abstract
Purpose: This study aims to evaluate the antimicrobial effects of the cholecalciferol vitamin
D3 against Streptococcus sobrinus (Strep. sobrinus) and Streptococcus mutans (Strep.
mutans) bacteria in vitro that is considered the main causative bacteria in dental
caries development. Materials and methods: The antimicrobial effects of vitamin D3 were evaluated against Strep. sobrinus
and Strep mutans using the agar disc diffusion method. The minimum inhibitory
concentration (MIC) and minimum bactericidal concentration (MBC) of vitamin
D3 were determined using a microdilution method following the guidelines by
the Clinical Laboratory Standards Institute (CLSI). Scanning electron microscope
(SEM) was used to evaluate the morphological changes of bacterial cells following
exposure to vitamin D3. Results: Strep. sobrinus was more sensitive to vitamin D3 compared to Strep. mutans bacteria.
The MIC values of vitamin D3 against Strep. sobrinus and Strep. mutans were 60 μg/
mL and 250 μg/mL respectively whereas the MBC values were 120 μg/mL and 500
μg/mL, respectively. Moreover, significant changes in the bacterial morphology
were observed in treated bacterial cells with vitamin D3 as compared to the
untreated control bacteria using SEM. Conclusion: These findings suggested that vitamin D3 has excellent antimicrobial effects against
Strep. sobrinus and Strep. mutans and may be considered as a promising compound
in the prevention of dental caries in the future. Further research is recommended to
elucidate the mechanism of vitamin D3 on these bacteria.

Serum Levels of Vitamin D and Dental Caries in 7-Year-Old Children in Porto Metropolitan Area. Nutrients 2021; 13:nu13010166. [PMID: 33430295 PMCID: PMC7825719 DOI: 10.3390/nu13010166] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Revised: 01/01/2021] [Accepted: 01/04/2021] [Indexed: 12/15/2022] Open
Abstract
Vitamin D deficiency has been associated with significant changes in dental structures. In children, it can induce enamel and dentin defects, which have been identified as risk factors for caries. This study aimed to assess the association between low serum 25-hydroxyvitamin D (25(OH) D) levels (<30 ng/mL) and the prevalence of caries in the permanent teeth and mixed dentition of 7-year-old children. A sample of 335 children from the population-based birth cohort Generation XXI (Porto, Portugal) was included. Data on children’s demographic and social conditions, health status, dental health behaviours, dental examination including erupted permanent first molars, and blood samples available for vitamin D analysis were collected. Dental outcomes included the presence of caries, including non-cavitated lesions (d1–6mft/D1–6MFT > 0), and advanced caries (d3–6mft/D3–6MF > 0). Serum 25(OH) D was measured using a competitive electrochemiluminescence immunoassay protein-binding assay. Bivariate analysis and multivariate logistic regression were used. Advanced caries in permanent teeth was significantly associated with children’s vitamin D levels <30 ng/mL, gastrointestinal disorders, higher daily intake of cariogenic food, and having had a dental appointment at ≤7 years old. Optimal childhood levels of vitamin D may be considered an additional preventive measure for dental caries in the permanent dentition.

Abstract
Vitamin D (VD) levels have been gaining growing attention in Oral Health. During growth and adulthood, VD deficiency (VDD) is associated with a wide variety of oral health disorders, and impaired VD synthesis may expedite some of these conditions. In children, severe VDD can induce defective tooth mineralization, resulting in dentin and enamel defects. As a consequence, these defects may increase the risk of the onset and progression of dental caries. Further, VDD has been associated with higher prevalence of periodontitis and gingival inflammation, and several recent preclinical and clinical studies have unveiled potential pathways through which Vitamin D may interact with the periodontium. VDD correction through supplementation may contribute to a successful treatment of periodontitis; however, alveolar bone regeneration procedures performed in baseline VDD patients seem more prone to failure. Vitamin D may also be linked with some oral pathology entities such as certain oral cancers and events of osteonecrosis of the jaw. This review aims to provide comprehensive evidence of how VD levels should be considered to promote good oral health, and to summarize how VDD may hamper oral development and its role in certain oral conditions.

A Review of the Potential Benefits of Increasing Vitamin D Status in Mongolian Adults through Food Fortification and Vitamin D Supplementation. Nutrients 2019; 11:nu11102452.

Abstract
Serum 25-hydroxyvitamin D (25(OH)D) concentrations are low in Mongolia, averaging 22 ng/mL in summer and only 8 ng/mL in winter. Mongolians have high incidence and/or prevalence of several diseases linked to low 25(OH)D concentrations, including ischemic heart disease, malignant neoplasms, cirrhosis of the liver, ischemic stroke, lower respiratory tract infections, preterm birth complications, and diabetes mellitus. Fortifying regularly consumed foods such as flour, milk, and edible oils with vitamin D3 could raise 25(OH)D concentrations by about 10 ng/mL. However, to achieve 25(OH)D concentrations of 30–40 ng/mL in adults, vitamin D intakes of 1000 to 4000 IU/day would be required, making personal supplement use necessary. On the basis of prospective observational studies and clinical trials of disease incidence or known mortality rates and adverse pregnancy and birth outcomes, raising mean serum 25(OH)D concentrations to 40 ng/mL would likely reduce incidence and mortality rates for those and other diseases, reduce the rate of adverse pregnancy and birth outcomes, and increase mean life expectancy by one year or more.

[PMID: 30804998 PMCID: PMC6360574 DOI: 10.1155/2019/2172137] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2018] [Revised: 10/21/2018] [Accepted: 11/05/2018] [Indexed: 12/29/2022] Open
Abstract
Vitamin D deficiency is a common risk factor for multifactorial diseases, and it seems to be associated with growth hormone deficiency (GHD). Vitamin D could prevent dental caries. The goal of this study was to identify whether there is an association between hormonal therapy with growth hormone (GH), vitamin D3 supplementation, vitamin D3 levels, and the occurrence of caries among children affected by GHD. The study group consisted of patients from the Department of Endocrinology and Diabetology of the University Paediatric Hospital at the Medical University of Lublin treated with recombinant human GH for pituitary GHD. It was conducted between October 2014 and June 2015. The study group included 121 children and adolescents aged 6 to 18 years, with 56 children from rural areas and 65 from urban areas. The study group was stratified by the area of residence. We found the statistically significant impact of vitamin D3 concentration on the average value of the DMFT (decayed, missed, and filled teeth) index and its component-DT (decayed teeth), which was noted in subjects from rural areas. Among patients from urban areas, we found a statistically significant correlation between duration of therapy and the DMFT index. An increase in duration of GH therapy by 10 months leads to a mean increase in DMFT index by 0.70. Based on multiple regression analysis, we developed the following model: value of DT = 3.10 - 0.73∗category of vitamin D3 concentration - 0.07∗duration of supplementation (in months). In this model, variables with a significant impact on the value of DT in the group of patients from rural areas include time of vitamin D3 supplementation and category of vitamin D3 concentration. Greater emphasis should be placed on promoting vitamin D3 as a potentially effective agent reducing the number of dental caries, especially among patients with GHD.

Abstract
Dental caries remains one of the most common chronic diseases affecting children worldwide with a multi-factorial etiology. The objective of the study was to evaluate the association between socioeconomic status (SES), dietary intake, food insecurity (FI), and dental caries in Korean children and adolescents. The study utilized data from the 2-year Korean National Health and Nutrition Examination Survey (KNHANES) conducted with 1,559 Korean boys and 1,391 girls aged 2 to 18 years from 2012 to 2013. Fathers' education (P=0.017), mothers' education (P<0.001), and household income (P=0.049) were all significantly associated with dental caries among Korean boys. As for dietary practices, both eating breakfast (P<0.001) and frequency of eating out (P<0.001) were strongly associated with dental caries (P<0.001). Three models of FI were used and no differences were found regarding genders. In model 3, both food insecure male [odds ratio (OR)=1.682, 95% confidence interval (CI): 0.999~2.832] and female (OR=1.900, 95% CI: 1.094~3.299) subjects had higher odds of developing dental caries than food secure subjects after adjusting the confounding factors. The present study showed a strong association between FI mediated by SES and dental caries. Nutrition education programs targeting low-socioeconomic families are necessary as a tool to prevent dental caries in Korea.

Abstract
BACKGROUND Severe early childhood caries (S-ECC) is common and has adverse affects on children's health. Children with S-ECC have been shown to have anemia or vitamin D deficiency. No studies have assessed the presence of combined deficiencies with S-ECC. The purpose of our study was to examine whether those with S-ECC had a higher prevalence of combined anemia and low 25-hydroxyvitamin D (25(OH)D) compared to controls. Covariates associated with elevated parathyroid hormone (PTH), previously noted in S-ECC, were examined. METHODS This is a re-analyses of a previously described cross-sectional case-control study; data were collected between 2009 and 2011. Children with S-ECC were recruited on the day of dental surgery and controls from the community. Blood was drawn for complete blood count, ferritin, 25(OH)D and PTH. Families completed a questionnaire. RESULTS A total of 266 children participated (S-ECC n=144); the mean age was 40.8 ± 14.1 months. Children with S-ECC were more likely to have low 25(OH)D, hemoglobin, elevated PTH or iron-deficiency anemia compared to controls. Significant differences between groups were seen for a combined deficiency of low hemoglobin (<110 g/L) and 25(OH)D < 50 nmol/L; controls 0/114 versus S-ECC 15/140 (P<0.001). In an adjusted regression model, PTH was negatively associated with 25(OH)D (P<0.001) and higher income (P<0.02); it was positively associated with less regular milk consumption (P=0.001). CONCLUSIONS Combined deficiencies of vitamin D and anemia are more prevalent in children with S-ECC; the etiology remains unclear. A detailed diet history is key in those with S-ECC to assess risks for deficiencies.

Abstract
AIM To compare the levels of vitamin D in children with severe early childhood caries (SECC) and children without caries and to determine the association of vitamin D deficiency and SECC. MATERIALS AND METHODS A total of 30 children each from case (with caries) and control group (without caries) of age between 3 and 6 years were selected from the Department of Pedo-dontics and Preventive Dentistry, Faculty of Dental Sciences, SGT University, Gurugram. Caries status of the children was recorded using decayed, extracted, and filled teeth (deft) index. Blood samples for serum 25(OH) vitamin D were taken from each child. All the data collected were compiled and subjected to appropriate statistical analysis. RESULTS Case group has mean serum 25(OH) vitamin D level of 12.19 ng/mL [4.37 standard deviation (SD), 95% confidence interval of 10.5-13.8] and control group has mean serum 25(OH) vitamin D level of 20.11 ng/mL (4.12 SD, 95% confidence interval of 18.56-21.65). When the mean levels of serum 25(OH) vitamin D were compared between case and control groups, there was a statistically significant difference (p-value <0.0001). Simple linear regression in case group shows statistically significant inverse correlation between vitamin D levels and SECC (p-value<0.0001). CONCLUSION Our results showed that vitamin D deficiency is risk factor both for incidence of dental caries and for its severity in children. CLINICAL SIGNIFICANCE Vitamin D deficiency is an important modifiable risk factor for dental caries in children. Hence, by supplementing vitamin D in children and preventing the deficiency of vitamin D, dental caries can be prevented.How to cite this article: Chhonkar A, Gupta A, Arya V.

Abstract
Vitamin D may prevent dental caries. To date, no attempts have been made to examine the correlation between the incidence of caries and the concentrations of vitamin D in children with pituitary growth hormone deficiency.The study observed patients of the Department of Endocrinology and Diabetology of the University Paediatric Hospital of the Medical University of Lublin treated with human recombinant growth hormone for pituitary growth hormone deficiency (GHD). The study was conducted between October 2014 and June 2015. The study group consisted of 121 children and adolescents (6-17 years old), including 56 children from rural areas and 65 children from urban areas. The study group was stratified by area of residence.In our study, the increase in vitamin D3 [25(OH)D] levels reduced the D component by 0.66 per each 10 ng/mL of vitamin D3 concentration. The percentage of children with active caries in rural areas is 91.07% (n = 51), which is significantly higher than the percentage of children with active caries in urban areas (81.54%, n = 53).To date, information regarding the potential possibility of reducing the incidence of dental caries by means of increasing the levels of vitamin D was sidelined by paediatricians and dentists alike. Therefore, this aspect of caries prevention should be highlighted.

Vitamin D Compounds Are Bactericidal against Streptococcus mutans and Target the Bacitracin-Associated Efflux System. Antimicrob Agents Chemother 2017; 62:AAC.01675-17.

Abstract
Vitamin D analogs were identified as compounds that induced lysis of planktonic cultures of Streptococcus mutans in a high-throughput screen of FDA-approved drugs. Previous studies have demonstrated that certain derivatives of vitamin D possess lytic activity against other bacteria, though the mechanism has not yet been established. Through the use of a combinatorial approach, the vitamin D derivative doxercalciferol was shown to act synergistically with bacitracin, a polypeptide-type drug that is known to interfere with cell wall synthesis, suggesting that doxercalciferol may act in a bacitracin-related pathway. Innate resistance to bacitracin is attributed to efflux by a conserved ABC-type transporter, which in S. mutans is encoded by the mbrABCD operon. S. mutans possesses two characterized mechanisms of resistance to bacitracin, the ABC transporter, S. mutans bacitracin resistance (Mbr) cassette, consisting of MbrABCD, and the rhamnose-glucose polysaccharide (Rgp) system, RgpABCDEFGHI. Loss of function of the transporter in ΔmbrA and ΔmbrD mutants exacerbated the effect of the combination of doxercalciferol and bacitracin. Despite conservation of a transporter homologous to mbrABCD, the combination of doxercalciferol and bacitracin appeared to be synergistic only in streptococcal species. We conclude that vitamin D derivatives possess lytic activity against S. mutans and act through a mechanism dependent on the bacitracin resistance mechanism of MbrABCD.

Abstract
BACKGROUND Vitamin D is hypothesized to reduce risk for tooth loss via its influence on bone health, inflammation, and the immune response. The association between plasma 25-hydroxyvitamin D [25(OH)D] concentrations and prevalence and 5-year incidence of tooth loss in a cohort of postmenopausal females was examined. METHODS Participants underwent oral examinations at study baseline (1997 to 2000) and follow-up (2002 to 2005) to determine the number of missing teeth and 5-year incidence of tooth loss, respectively. At both visits, females self-reported reasons for each missing tooth. At baseline, 152 females reported no history of tooth loss, and 628 were categorized as reporting a history of tooth loss as a result of periodontal disease (n = 70) or caries (n = 558) (total n = 780). At follow-up, 96, 376, 48, and 328 females were categorized into the aforementioned categories related to tooth loss (total n = 472). Logistic regression was used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) for tooth loss by category of baseline 25(OH)D (nmol/L) concentrations. Models were adjusted for age, income, smoking status, frequency of dental visits, waist circumference, and recreational physical activity. P value for trend was estimated using continuous concentrations of 25(OH)D. RESULTS Among females with 25(OH)D ≥50 (adequate vitamin D status) compared to <50 nmol/L (deficient/inadequate), the adjusted ORs were 1.24 (95% CI = 0.82 to 1.87), P-trend = <0.05 for the history (prevalence) of tooth loss resulting from periodontal disease or caries and 1.07 (95% CI = 0.62 to 1.85), P-trend = 0.11 for the incidence of tooth loss resulting from periodontal disease or caries. No statistically significant association was observed between 25(OH)D and the history or incidence of tooth loss caused by periodontal disease. An increased odds of the history of tooth loss attributable to caries was observed with increasing concentrations of 25(OH)D (P-trend = <0.05) but was not confirmed in prospective analyses. CONCLUSION In this cohort of postmenopausal females, the data do not support an association between vitamin D status and tooth loss.

Abstract
Low maternal vitamin D levels during pregnancy have been associated with a plethora of adverse neonatal outcomes, including small for gestational age and preterm births, detrimental effect on offspring bone and teeth development, and risk of infectious diseases. Although most observational studies indicate a significant linear relationship between maternal 25-hydroxyvitamin D and the above outcomes, some randomized controlled trials to date are inconclusive, mostly due to differences in study design and supplementation regimen. The currently available results indicate that vitamin D supplementation during pregnancy reduces the risk of preterm birth, low birth weight, dental caries of infancy, and neonatal infectious diseases such as respiratory infections and sepsis. This narrative review aims to summarize available trial results regarding the effect of low maternal vitamin D levels during pregnancy, in conjunction with neonatal outcomes on the field, with a discourse on the appropriate clinical approach of this important issue.

Abstract
Using a variety of approaches, researchers have studied the health effects of solar ultraviolet (UV) radiation exposure and vitamin D. This review compares the contributions from geographical ecological studies with those of observational studies and clinical trials. Health outcomes discussed were based on the author's knowledge and include anaphylaxis/food allergy, atopic dermatitis and eczema, attention deficit hyperactivity disorder, autism, back pain, cancer, dental caries, diabetes mellitus type 1, hypertension, inflammatory bowel disease, lupus, mononucleosis, multiple sclerosis, Parkinson disease, pneumonia, rheumatoid arthritis, and sepsis. Important interactions have taken place between study types; sometimes ecological studies were the first to report an inverse correlation between solar UVB doses and health outcomes such as for cancer, leading to both observational studies and clinical trials. In other cases, ecological studies added to the knowledge base. Many ecological studies include other important risk-modifying factors, thereby minimizing the chance of reporting the wrong link. Laboratory studies of mechanisms generally support the role of vitamin D in the outcomes discussed. Indications exist that for some outcomes, UVB effects may be independent of vitamin D. This paper discusses the concept of the ecological fallacy, noting that it applies to all epidemiological studies.

Abstract
Background Previous studies have reported an inverse association between vitamin D and childhood dental caries, but whether this is causal is unclear. Objective To determine the causal effect of circulating 25-hydroxyvitamin D concentration on dental caries experience, early caries onset and the requirement for a dental general anesthetic. Design A Mendelian randomization study was undertaken, using genetic variants known to be associated with circulating 25-hydroxyvitamin D concentrations in 5,545 European origin children from the South West of England. Data on caries and related characteristics were obtained from parental and child completed questionnaires between 38 and 91 months and clinical assessments in a random 10% sample at 31, 44 and 61 months. Results In multivariable confounder adjusted analyses no strong evidence for an association of 25-hydroxyvitamin D with caries experience or severity was found but there was evidence for an association with early caries onset, or having a general anesthetic for dental problems. In Mendelian randomization analysis the odds ratio for caries experience per 10 nmol/L increase in 25-hydroxyvitamin D was 0.93 (95% confidence interval: 0.83, 1.05; P = 0.26) and the odds ratio for dental general anaesthetic per 10 nmol/L increase in 25-hydroxyvitamin D was 0.96 (95% confidence interval: 0.75, 1.22; P = 0.72). Conclusions This Mendelian randomization study provides little evidence to support an inverse causal effect of 25-hydroxyvitamin D on dental caries. However, the estimates are imprecise and a larger study is required to refine these analyses.

Abstract
People with neurodevelopmental disorders and intellectual disabilities have much greater health care needs. Mainly staying indoors, such people generally have low 25-hydroxyvitamin D (25(OH)D) concentrations. The Vitamin D Task Force of the American Academy of Developmental Medicine and Dentistry (AADMD) reviewed the evidence of 25(OH)D concentrations that benefit the health of persons with developmental disabilities. Maintaining recommended optimal serum 25(OH)D concentrations year long will benefit skeletal development in infants, children, and adolescents, and benefit musculoskeletal health and neuromuscular coordination in adult patients, and decrease risk of falls. Maintaining optimal concentrations decreases risks and severities of autoimmune diseases, cardiovascular disease, many types of cancer, dementia, types 1 and 2 diabetes mellitus, and respiratory tract infections. Other benefits include improved dental and oral health and improved physical performance. The Task Force recommends that 25(OH)D concentrations for optimal health to be in the range of 75 to 125 nmol/L, which can be achieved using between 800 and 4000 IU/day vitamin D3 and sensible exposure to solar UVB radiation. The paper also discusses the potential risks of higher 25(OH)D concentrations, the evidence from and limitations of randomized controlled trials, and the recommendations by various groups and agencies.

Abstract
To date, the precise etiology of molar-incisor hypomineralization (MIH) is uncertain. Vitamin D plays a key role in hard tissue formation. Therefore, this study aimed to analyze the relationship between serum 25-hydroxy-vitamin D (25(OH)D) status and dental health data obtained from 1,048 children in a 10-year follow-up of the Munich GINIplus and LISAplus birth cohorts. The dental examination included the diagnosis of MIH and recording of (non-)cavitated caries lesions in primary and permanent teeth. Serum 25(OH)D concentrations were taken from blood samples of the 10-year investigation and measured with a fully automated, modular system. Different logistic regression and Poisson hurdle models were calculated. MIH was diagnosed in 13.6% of the study population. Approximately 16.4% of the children demonstrated caries-related defects (D3-4MFS > 0). The mean season-adjusted concentration of 25(OH)D was 75.8 nmol/l (standard deviation 22.0 nmol/l). After adjusting for sex, age, body mass index, parental education, equivalent income, and television/personal computer (TV/PC) viewing hours, a 10 nmol/l increase in serum 25(OH)D concentrations was significantly associated with a lower odds ratio of having MIH (OR = 0.89; P = 0.006). Furthermore, higher 25(OH)D values were associated with a lower number of caries-affected permanent teeth. It is concluded that elevated serum 25(OH)D concentrations were associated with better dental health parameters.

Abstract
PURPOSE Environmental influences on reproductive success are recognized. We hypothesized that location of fertility clinics may influence treatment success and explored this hypothesis utilizing donor egg IVF (IVF) embryo transfer (ET) model. METHODS Publicly accessible national registry data (Society for Assisted Reproductive Technology) on fresh & frozen (FET) ET cycles undertaken at participating clinics across North America (n = 444 IVF centers) for 2007 were utilized. Information on number of donor egg IVF cycles, live birth (LB) rate following fresh and frozen ET(FET), average number (#) of ET and IVF center's location, geographical coordinates (latitude, longitude, altitude), annualized average temperatures and midyear regional ultraviolet B (UVB) radiation intensity were obtained. Multivariable logistic regression analyses assessed relationship between LBR (in tertile and uppermost versus lesser quartiles) following fresh and FET with geographical coordinates (region and altitude of clinic location) and ecological influences (average temperature and midyear UVB intensity), adjusting for #ET and clinic experience with donor egg IVF. RESULTS Average number of fresh ET, clinic location (region) and midyear UVB intensity were positive predictors of LBR following fresh ET, whereas altitude and annualized average regional temperature demonstrated an inverse relationship with LBR following fresh ET. For FET cycles, #ET, clinic region and altitude were positive determinants of increasing LBR's. Annualized regional temperature and midyear UVB failed to demonstrate any relationship with LB following donor egg FET. CONCLUSION Our data suggest that ecological influences may relate to donor egg IVF cycle success. Future studies are needed to better elucidate the mechanisms that could explain the observed associations.

Abstract
Vitamin D deficiency and oral diseases (periodontitis, caries, and tooth loss) are highly prevalent in Germany. Previous studies suggested that vitamin D might be a modifiable and protective factor for periodontitis, caries, and tooth loss. However, prospective studies investigating such associations are limited. We explored the association between the concentration of serum 25-hydroxy vitamin D (25OHD) and incidence of tooth loss, progression of clinical attachment loss (CAL) ≥ 3 mm, and progression of restorative and caries status in a population-based longitudinal study. We analyzed data from 1,904 participants from the Study of Health in Pomerania with a five-year follow-up. Generalized estimating equation models were applied to evaluate tooth-specific associations between serum 25OHD and incidence of tooth loss, progression of CAL ≥ 3 mm, and progression of restorative and caries status. Age, sex, education, smoking status, alcohol drinking, waist circumference, dental visit frequency, reasons of dental visit, vitamin D or calcium supplements, and season of blood draw were considered as confounders. Serum 25OHD was inversely associated with incidence of tooth loss. A significant dose-response relationship (p = .0022) was observed across the quintiles of serum 25OHD. After adjusting for multiple confounders, each 10-µg/L increase of serum 25OHD was associated with a 13% decreased risk of tooth loss (risk ratio: 0.87; 95% confidence interval: 0.79, 0.96). The association was attenuated for changes of CAL ≥ 3 mm when adjusting for multiple confounders. No significant association was found between serum 25OHD and caries progression. Vitamin D might be a protective factor for tooth loss. The effect might partially be mediated by its effect on periodontitis.

Abstract
BACKGROUND Severe Early Childhood Caries (S-ECC) affects the health and well-being of young children. There is limited research in this area, though evidence suggests that children with S-ECC are at an increased risk of malnutrition. The purpose of this study was to determine the association between vitamin D (25(OH)D) levels and S-ECC. METHODS This case-control study was conducted from 2009 to 2011 in the city of Winnipeg, Manitoba, Canada. 144 preschool children with S-ECC were recruited from a local health centre on the day of their slated dental surgery under general anesthetic. 122 caries-free controls were recruited from the community. Children underwent a blood draw for vitamin D (25(OH)D), calcium, parathyroid hormone, and albumin levels. Parents completed an interviewed questionnaire assessing the child's nutritional habits, oral health, and family demographics. Analyses included descriptive and bivariate statistics as well as multiple and logistic regression. A p value ≤ 0.05 was significant. RESULTS The mean age of participants was 40.8 ± 14.1 months. Children with S-ECC had significantly lower mean 25(OH)D (68.9 ± 28.0 nmol/L vs. 82.9 ± 31.1, p < 0.001), calcium (p < 0.001), and albumin (p < 0.001) levels, and significantly higher parathyroid hormone (p < 0.001) levels than those caries-free. Children with S-ECC were significantly more likely to have vitamin D levels below recognized thresholds for optimal and adequate status (i.e. < 75 and < 50 nmol/L, respectively). Multiple regression analysis revealed that S-ECC, infrequent milk consumption, and winter season were significantly associated with lower 25(OH)D concentrations. Low 25(OH)D levels, low household income, and poorer ratings of the child's general health were significantly associated with S-ECC on logistic regression. CONCLUSION Children with S-ECC appear to have relatively poor nutritional health compared to caries-free controls, and were significantly more likely to have low vitamin D, calcium, and albumin concentrations and elevated PTH levels.

This review paper describes the applications of dental optical coherence tomography (OCT) in oral tissue images, caries, periodontal disease and oral cancer. The background of OCT, including basic theory, system setup, light sources, spatial resolution and system limitations, is provided. The comparisons between OCT and other clinical oral diagnostic methods are also discussed.
