Abstract
Background: To assess whether vitamin D receptor (VDR) gene polymorphisms influence the susceptibility to periodontitis. Methods: We retrieved 34 relevant studies, comprising a total of 3848 subjects suffering from periodontitis and 3470 controls for this meta-analysis. The pooled data were analyzed using STATA software. Results: Among all ethnic groups examined, the VDR BsmI polymorphism was associated with periodontitis under the recessive model (odds ratio [OR] = 0.722, 95% confidence interval [CI]: 0.532-0.980, p = 0.037). There was also a link between the VDR FokI polymorphism and periodontitis in the overall population (dominant model: OR = 1.459, 95% CI: 1.050-2.028, p = 0.025 and allelic model: OR = 1.386, 95% CI: 1.026-1.874, p = 0.034) and in Chinese participants (dominant model: OR = 1.813, 95% CI: 1.185-2.774, p = 0.006; allelic model: OR = 1.602, 95% CI: 1.044-2.459, p = 0.031) when stratified by race. The FokI variant was also correlated with aggressive periodontitis (AP) (dominant model: OR = 2.204, 95% CI: 1.148-4.231, p = 0.018; allelic model: OR = 2.017, 95% CI: 1.365-2.980, p = 0.000; and recessive model: OR = 2.903, 95% CI: 1.520-5.542, p = 0.001). We also showed a correlation between the VDR TaqI variant and periodontitis susceptibility in Caucasian populations (dominant model: OR = 0.525, 95% CI: 0.318-0.866, p = 0.012). The results revealed that there was no relationship between the VDR ApaI gene polymorphism and periodontitis. Conclusions: There was a link between the VDR BsmI and FokI gene polymorphisms and periodontitis in the overall population. In addition, the FokI polymorphism was correlated with AP. There was a link between the TaqI polymorphism and periodontitis in the Caucasian population. The VDR Apal variant, however, was not correlated with periodontitis.

Abstract
AIM The aim of the present study was to analyze the association between vitamin D receptor (VDR) (rs10735810) gene polymorphism and chronic periodontitis (CP). METHODS A total of 100 subjects were recruited for this study, which included 50 CP and 50 healthy controls. Genomic DNA was extracted from the whole blood collected from the subjects. DNA was amplified using specific primers flanking the FokI region of the VDR gene (rs10735810). The amplicon was further subjected to genotyping using restriction fragment length polymorphism (RFLP) using the FokI enzyme. The genotype obtained based on RFLP pattern was recorded and used for statistical analysis. The distribution of genotypes and allele frequencies in the chronic periodontitis and control groups were compared using the χ2 -test. RESULTS The CP group displayed the highest frequency of CT (20%) and TT (6%) genotypes when compared with the control subjects. Allele frequency was found to be similar in both groups. The C allele was found to be predominant in the study population compared with the T allele. CONCLUSION The present study denotes that the VDR polymorphism (rs10735810) is not associated with CP in the study group analyzed.

Abstract
BACKGROUND Chronic periodontitis (CP), defines as destruction of the supporting tissues of the teeth and resorption of the alveolar bone. It is widespread in human populations and represent an important problem for public health. CP results from inflammatory mechanisms created by the interaction between environmental and host genetic factors that confer the individual susceptibility to the disease. AIM The aim of the current study was to explore and summarize some functional biomarkers that are associated with CP susceptibility. METHODS CP is considered to be a multifactorial disease. The pathogenesis of multifactorial diseases is characterized by various biological pathways. The studies revealed that polymorphisms were associated with susceptibility to periodontal diseases. In other word, genetic variations can change the development of CP. However, there are some conflicting results, because there are different variations in frequency of some alleles in any populations. Therefore, we conducted the current review to completely understanding the special biomarkers for CP. RESULTS There is some evidence that SNPs in the IL-1α, IL-1β, IL1RN, IL-6, IL-10, TNF-α, TGF-β1, IFN-γ and VDR may be associated with CP susceptibility. CONCLUSION In conclusion, numerous studies have reported the host genetic factors associated with CP susceptibility and related traits. Therefore, it is prevail to study the multiple SNPs and their effects to find the useful diagnosis methods. The current study will investigate the relationship between polymorphisms in cytokine genes and the susceptibility to the chronic periodontitis.

Abstract
BACKGROUND There has been increasing interest in the study of the association between Vitamin D receptor (VDR) gene polymorphisms and risk of chronic periodontitis. However, the results remain inconclusive. To better understand the roles of VDR polymorphisms (BsmI, TaqI, FokI, and ApaI) in chronic periodontitis susceptibility, we conducted this systematic review and meta-analysis. MATERIALS AND METHODS The PubMed, Google Scholar, and Web of Science database were systemically searched to determine all the eligible studies about VDR polymorphisms and risk of chronic periodontitis up to April 2017. Odds ratio (OR) and 95% confidence interval (CI) were used to evaluate the associations between VDR polymorphisms and chronic periodontitis risk. All the statistical analyses were performed by Comprehensive Meta-Analysis. All P values were two-tailed with a significant level at 0.05. RESULTS Finally, a total of 38 case-control studies in 19 publications were identified which met our inclusion criteria. There are ten studies with 866 chronic periodontitis cases and 786 controls for BsmI, 16 studies with 1570 chronic periodontitis cases and 1676 controls for TaqI, five studies with 374 chronic periodontitis cases and 382 controls for FokI, and seven studies with 632 chronic periodontitis cases and 604 controls for ApaI. Overall, no significant association was observed between VDR gene BsmI, TaqI, FokI, and ApaI polymorphisms and risk of chronic periodontitis in any genetic model. Subgroup analysis stratified by ethnicity suggested a significant association between BsmI polymorphism and chronic periodontitis risk in the Caucasian subgroup under allele model (A vs. G: OR = 1.747, 95% CI = 1.099-2.778, P = 0.018). Further, no significant associations were observed when stratified by Hardy-Weinberg equilibrium status for BsmI, TaqI, and ApaI. CONCLUSION Our results suggest that BsmI, TaqI, FokI, and ApaI polymorphisms in the VDR gene might not be associated with risk of chronic periodontitis in overall population.

Abstract
BACKGROUND Osteoporosis, a multifactorial disease with reduced bone mineral density which increases the probability of bone fractures, is caused by calcium deficiency, and its incidence increases with age. It has been determined that mutations in functional regions of vitamin D receptor gene will affect the metabolism of minerals especially calcium and, therefore, bone density. The present study evaluates the relation between vitamin D receptor polymorphisms, TaqI (rs731236) and ApaI (rs7975232), and osteoporosis in menopausal Azari women in Zanjan province. MATERIALS AND METHODS This case-control study has been conducted on 50 menopausal women suffering from osteoporosis and 50 menopausal women who did not suffer from osteoporosis in Zanjan province. The diagnosis of osteoporosis was confirmed using DEXA instrument. Peripheral blood was collected from the subjects and controls to extract DNA and assess the ApaI and TaqI polymorphisms using PCR-RFLP method. The results were interpreted using independent T-test, chi-square, and Pearson correlation coefficient with a p-value less than 0.05. RESULTS There was not a significant difference between the frequency of ApaI (AA/Aa/aa) and TaqI (TT/Tt/tt) genotypes in cases (mean age 68.72) and controls (mean age 64.7) (p=0.37 and p=0.64, respectively). In addition, ApaI/TaqI allele haplotype in osteoporotic population showed non-significant relation (p value=0.563) compared with the control group. DISCUSSION AND CONCLUSION The relationship between the genotypes and osteoporosis, cancers, and mineral metabolism disorders has been studied for a long time. Although there has been a significant relation between the aforementioned genotypes and osteoporosis or reduced mineral density-related bone fractures in some studied, some other studies have opposing results. Therefore, it is only possible to reach an acceptable conclusion by studying the haplotype of the polymorphisms in subjects.

Abstract
AIM We analyzed the VDR TaqI (rs731236) gene polymorphism in children with and those without dental caries. METHODS A total of 388 subjects, 153 caries-free (with decayed/missing/filled teeth [DMFT] = 0) and 235 children with dental caries (DMFT ≥1), were genotyped by the TaqMan method. RESULTS Although no significant differences in VDR TaqI allele and genotype frequencies between caries-free and caries-affected children were detected, a significant association between this polymorphism and gingivitis was found (p < 0.05). CONCLUSIONS In contrast to previous studies from China and Turkey, the VDR TaqI gene variant cannot be used as a marker for identification of Czech children with increased dental caries risk.
