Abstract
BACKGROUND This meta-analysis evaluated the association of LTF, ENAM, and AMELX polymorphisms with dental caries susceptibility. METHODS We searched the Scopus, PubMed/Medline, Web of Science, and Cochrane Library databases to retrieve articles published by October 2019. Review Manager 5.3 software was used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs). The results of publication bias tests were retrieved by Comprehensive Meta-Analysis 2.0 software. RESULTS A total of 150 relevant records were identified; out of which, 16 were entered into the analysis (4 studies assessed LTF, 11 ENAM, and 11 AMELX polymorphisms). Of all polymorphisms, there was a significant association only between ENAM rs3796704 polymorphism and dental caries susceptibility. Both ENAM rs3796704 and AMELX rs17878486 polymorphisms had a significant association with dental caries risk in the Caucasian ethnicity and the studies including caries-free control group. CONCLUSIONS The results of this meta-analysis showed that the G allele and the GG genotype of ENAM rs3796704 were associated with an increased risk of caries in the case group compared with the control group. But there was no association between LTF rs1126478, ENAM (rs1264848 and rs3796703), and AMELX (rs946252, rs17878486, and rs2106416) polymorphisms and dental caries susceptibility.

Abstract
BACKGROUND Dental caries and periodontal diseases are the most common oral diseases among human beings. Individuals with intellectual disabilities (IDs) have poor oral health and limited access to dental care. The aim of this study was to investigate the efficacy of strategies in caries and gingivitis prevention among children and adolescents with ID. METHODS Four electronic databases (PubMed, Cochrane Library, Web of Science and Scopus) were searched from their commencement date to 17 April 2017. Randomised or non-randomised controlled trials evaluating the efficacy of interventions in caries and gingivitis prevention were included if the participants were children and adolescents with ID. Gingival index and caries experiences were reported in the format of mean difference and standard error. Meta-analysis was conducted if data could be pooled from two or more studies using similar outcome measurements and intervention. RESULTS A total of 1455 articles published in English were identified. Fourteen studies formed the basis of qualitative analysis; six studies were feasible to perform quantitative analysis. Meta-analysis favoured fluoride to placebo in caries prevention [Z = 2.02, P < 0.05, 95% CI: -0.71 (-1.40, -0.02)], while the effectiveness of chlorhexidine remained elusive. CONCLUSIONS Both mechanical and chemical approaches had been applied to caries and gingivitis prevention among children and adolescents with ID. Insufficient evidence supported the efficacy of chlorhexidine nor powered toothbrush, while fluoride was suggested to be an effective caries preventive strategy in fluoride-deficient areas. More well-designed randomised controlled trials using integration strategies are encouraged in further studies.

Abstract
The study aimed to evaluate the efficacy of the combination of CPP-ACP and fluorides compared with fluorides monotherapy on patients with early caries lesions. The Medline, Embase and Cochrane databases up to August 2017 were scanned, with no restrictions. Studies satisfied the guideline of randomised controlled trials (RCTs), the patients with early caries lesions and data considering the efficacy of fluorides and CPP-ACP versus fluorides alone were selected. There was no language restriction during the literature search process, however, only papers in English or Chinese were included during the selection process. Outcome variables include laser fluorescence, quantitative light-induced fluorescence, lesion area and visual inspection scores. Mean differences were calculated during the data extraction process. Ten studies including 559 patients were selected in the meta-analysis. Fluorides combined with CPP-ACP achieved the same efficacy for early caries lesions on smooth surfaces compared with fluorides monotherapy (mean difference: -13.90, 95% confidence interval: [-39.25, 11.46], P = 0.28), and the combination treatment showed significantly better efficacy than fluorides monotherapy for occlusal early caries lesions (mean difference: -21.02, 95% confidence interval: [-27.94, -14.10], P<0.01). However, further well-designed studies are still needed.
