Vitamin D is a steroid hormone that produced primarily by sunlight exposure or obtained from dietary sources, including supplements. The persons who are normally at risk of Vitamin D deficiency are those with scarce of sun exposure and diminished intestinal absorption or limited oral intake. Teeth are nothing but mineralized structure which is enclosed by alveolar bone and are developed by 3 different hard tissues such as dentin, enamel, and cementum. Vitamin D plays a predominant vital part in the tooth and bone mineralization, and it can result in rachitic tooth when the levels get unregulated. Studies suggest that Vitamin D deficiency causes hypocalcified dentin and delayed tooth eruption; thus, representing that Vitamin D has a crucial role in dentin formation as well. The beneficial effects of vitamin D on oral health are not only limited to the direct effects on the tooth mineralization but are also applied through ability to stimulate the production of anti-microbial peptides. In this article, we will briefly discuss the influence on Vitamin D level on the oral and pulpal health.

Vitamin D deficiency is not uncommon even in the sunny land of India. Lack of sun exposure and inadequate oral intake are both responsible for vitamin D deficiency. This article provides a retrospective, examining the effects of Vitamin D deficiency in 71 patients. The study's inclusion criterion was low vitamin D level combined with musculoskeletal symptoms but without the presence of osteomalacia. All patients in this study were suspected to have vitamin D deficiency. The data were retrieved from the case-charts of patients seen between 1996 and 2001 at the rheumatology services of Hinduja Hospital, Mumbai, India. This study found no correlation between Vitamin D levels and symptoms, or between the severity of Vitamin D deficiency and the number of symptoms displayed. Subclinical vitamin D deficiency or preosteomalacic state was the term coined for individuals with vitamin D deficiency producing nonspecific musculoskeletal symptoms in the absence of clinical osteomalacia.

Abstract Objective: Vitamin D is an essential vitamin for bone mineralization and its deficiency adversely affects many systems, predominantly the musculoskeletal system. A lack of synthesis in the skin is the key step that predominantly causes vitamin D deficiency. Vitamin D synthesis can be affected by numerous factors including geographical region of residence, seasons, monthly average daily global horizontal solar radiation (MADGHSR), monthly average daily sunshine duration (MADSD), ethnic group of the individual. The study aimed to investigate the relationship between vitamin D level and MADSD and MADGHSR values in young women. Methods: The retrospective study included women aged 15-45 years, who presented to Secondary Care Hospital for general health screening. Vitamin D levels were classified according to age groups, months, seasons, MADGHSR and MADSD values. Results: The mean vitamin D level was 17.3±7.3 ng/mL in summer and was 15.9±7.5 ng/mL in winter (p=0.001). Vitamin D deficiency (<20 ng/mL) was detected in 68.1% as opposed to 75.1% of women in summer and winter, respectively (p<0.001). A weak correlation was found between vitamin D level and age (r=0.082, p=0.002), MADGHSR (r=0.062, p=0.006), and MADSD (r=0.075, p=0.001). Conclusion: The individual and environmental factors with the MADGHSR, MADSD have a direct effect on sun exposure. The traditional and religious clothing habits of our participants constituted the most important factor contributing to their low vitamin D levels. We propose that routine vitamin D supplementation at optimal doses will be an appropriate approach in populations similar to the population studied in the present study.

Reduced Physical Activity

Vitamin D deficiency affects a large part of the population of elderly people, especially women, who live in moderate climate countries due to a reduced amount of vitamin D in the diet (small sea fish consumption) and reduced content of 7-dehydrocholesterol, which causes decreased skin synthesis. The lowest seasonal concentration of 25(OH)D3 is usually observed during winter and spring. Sun exposure influences 25(OH)D3 concentration more strongly in men than in women.Sociodemographic factors that increase the risk of vitamin D deficiency in the elderly include poor environmental conditions, low economic status, lower educational level, drug exposure (smoking), reduced physical activity, overall poor health and obesity, which causes reduced skin exposure to sunlight.The use of medications or supplements that contain vitamin D and staying in a nursing home that employ such supplementation are factors that prevent deficiency.Significant prevalence of diseases of the gastrointestinal tract may contribute to cholecalciferol and ergocalciferol malabsorption or impair their liver transformation. In addition, the high incidence of chronic kidney disease in old age reduces processing hydroxylation of vitamin D and the formation of active metabolites.Vitamin D deficiency can not only cause bone mineralization disorders, but also increase incidence of cardiovascular diseases, cancers, type 2 diabetes and depression.The aim of this study was to summarize current knowledge about the risk factors of vitamin D deficiency development in the elderly population.

Abstract. Background: Hypovitaminosis D is a vitamin deficiency that has been increasing in developed countries; it was also suggested as an emerging risk factor for developing of atherosclerosis and acute myocardial infarction. The primary source of vitamin D is its cutaneous synthesis under exposure to sunlight. It has been suggested that 30 min of sun exposure twice weekly leads to sufficient vitamin D synthesis. The residents of Trieste (Italy) are well-known for their high exposure to sunlight in all seasons. We aimed to investigate the vitamin D status in subjects with acute myocardial infarction living in this area. Methods: Vitamin D status was identified in 478 subjects diagnosed with acute myocardial infarction. Results: The median serum 25-hydroxyvitamin D concentration was 14.5 [7.8 - 22.7] ng/mL. Vitamin D deficiency and insufficiency were present in 324 (68 %) and 107 (22 %) subjects, respectively. Vitamin D deficiency was less frequent among subjects enrolled in the period from July to the end of September (p < 0.001). In a multivariate analysis vitamin D deficiency was predicted by older age (p = 0.02), female gender (p = 0.002), higher body mass index (p = 0.05), autumn/winter sampling (p < 0.001), increased parathyroid hormone (p = 0.03) and alkaline phosphatase (p = 0.003). Conclusions: We observed very high prevalence of vitamin D deficiency among subjects with myocardial infarction in all seasons of enrollment. However, it was lower in the summer when sun exposure is higher. The exposure to sunlight may be a cost-saving therapeutic strategy for the management of vitamin D deficiency.

Biologic Function

Major biologic function of activated vitamin D is to maintain normal blood levels of calcium and phosphorus, thus regulating bone mineralization. Research suggests that vitamin D may help in immunomodulation, regulating cell growth and 1,4 differentiation as well as some diverse unspecified functions. Overt vitamin D deficiency leads to hypocalcaemia, secondary hyperparathyroidism and increased bone turnover, which in prolonged and severe cases may cause rickets in children and osteomalacia in elderly....

Purpose Vitamin D deficiency is a well-recognised public health problem within the UK, with specific population groups more vulnerable to deficiency. Two pilot studies were used to explore awareness of vitamin D deficiency and attitudes towards food fortification. Design/methodology/approach A survey of 120 participants from five at-risk groups (South Asians, Blacks, Middle Eastern, Far Eastern and Caucasian older adults over 65 years) plus a group of British Caucasians who do not avoid sun exposure explored awareness of vitamin D, sun exposure knowledge and behaviour and attitudes towards food fortification. The latter group was included to provide a comparison group who were at a reduced risk of deficiency. χ2 was used to test associations between categorical variables and the study groups. The second study used three focus groups and two interviews, conducted on young South Asian females and examined knowledge and awareness of vitamin D and vitamin D-fortified foods. Findings A lack of knowledge and misconceptions were highlighted by both studies in relation to at-risk factors, including sunlight exposure (p = 0.037), dietary intakes (p = 0.0174) and darker skin pigmentation (p = 0.023), sources of vitamin D and the health benefits associated with optimal consumption. Attitudes to mandatory fortification of some foods varied significantly (p = 0.004) between the groups with acceptance rates for Blacks (68 per cent), those over 65 years (50 per cent), Middle Eastern (67 per cent) and Far Eastern (73 per cent), whereas the control (71 per cent) showed no acceptance, and South Asians gave a mixed response (48 per cent No). Focus group findings highlighted positive views towards fortification, although this was less for mandatory as opposed to voluntary fortification. Both pilot studies highlight the need for more research into this area, to create more effective public health policies. Originality/value The research presents novel insights into a topical area where there is limited research.

Healthy Older Adults

Vitamin D deficiency is present even in sunny regions. Ageing decreases pre-vitamin D production in the skin and is associated with altered cytokine profile. We performed a multivariate analysis considering lifestyle factors, anthropometric, and inflammatory markers according to seasonal variation in Mexican healthy older adults. The same cohort was followed during 12 months. Vitamin D deficiency/insufficiency was found in 91.3% of the subjects despite living in appropriate latitude (25°40′0″N). 25(OH)D levels remained below <30 ng/mL through all seasons. Vitamin D deficiency did not correlate to sun exposure or dietary intake. Gender was the strongest associated factor, explaining a variance of 20%. Waist circumference (WC) greater than 88 cm was a risk factor for vitamin D deficiency. Age (>74 years) combined with WC (>88 cm) and BMI (>32.7) showed a high probability (90%) of vitamin D deficiency. Remarkably, an increase in one centimeter in WC decreased 25(OH)D by 0.176 ng/mL, while an increase in one point BMI decreased 25(OH)D by 0.534 ng/mL. A cutoff point of 74 years of age determined probability of vitamin D hipovitaminosis. Vitamin D deficiency was correlated with TNF-αserum levels, possibly increasing the susceptibility of older adults to a proinflammatory state and its related diseases.

Objective: Vitamin D deficiency is a global health problem. It is significantly associated with skeletal and non-skeletal problems. Prevention can be maintained mainly by effective sun exposure or supplementation and to lesser extent by dietary intake. To determine the magnitude of knowledge and practice of women towards vitamin D deficiency. Methods: A cross-sectional study, purposive sample of 442 women were approached who attended consultants’ clinics of Imam Hussein Medical City in Karbala. Data collection done between March 2 and June 30, 2018 through direct interviews using a special questionnaire prepared for the purpose of the study. Results: Less than half (45.2%) of the women had heard about vitamin D; their source of information was from relatives and friends then from health care provider. The mean score for the participants’ knowledge about VDD was 4.25 out of 9.0 (47%). It has a significant association with higher educational levels and urban residence. There is no significant difference regarding age, marital status or occupation. The mean score for the participants’ practice about vitamin D deficiency was 2.53 out of 5 (50.71%). There is no influence of practice score by socio-demographic factors. Conclusion: Overall knowledge towards vitamin D deficiency was suboptimal. Improving practices towards VD is directly related to increase knowledge about it that indicates the need to increase public awareness about the problem, encourage appropriate way of sun exposure, consumption of vitamin D rich food and taking supplementation when sun exposure is difficult.
