Xylitol pediatric topical oral syrup to prevent dental caries: a double-blind randomized clinical trial of efficacy.

ABSTRACT: To evaluate the effectiveness of a xylitol pediatric topical oral syrup to reduce the incidence of dental caries among very young children and to evaluate the effect of xylitol in reducing acute otitis media in a subsequent study.Double-blind randomized controlled trial.Communities in the Republic of the Marshall Islands.One hundred eight children aged 9 to 15 months were screened, and 100 were enrolled. Intervention Children were randomized to receive xylitol topical oral syrup (administered by their parents) twice a day (2 xylitol [4.00-g] doses and 1 sorbitol dose) (Xyl-2 x group) or thrice per day (3 xylitol [2.67-g] doses) (Xyl-3x group) vs a control syrup (1 xylitol [2.67-g] dose and 2 sorbitol doses) (control group).The primary outcome end point of the study was the number of decayed primary teeth. A secondary outcome end point was the incidence of acute otitis media for reporting in a subsequent report.Ninety-four children (mean [SD] age, 15.0 [2.7] months at randomization) with at least 1 follow-up examination were included in the intent-to-treat analysis. The mean (SD) follow-up period was 10.5 (2.2) months. Fifteen of 29 of the children in the control group (51.7%) had tooth decay compared with 13 of 32 children in the Xyl-3x group (40.6%) and eight of 33 children in the Xyl-2x group (24.2%). The mean (SD) numbers of decayed teeth were 1.9 (2.4) in the control group, 1.0 (1.4) in the Xyl-3x group, and 0.6 (1.1) in the Xyl-2x group. Compared with the control group, there were significantly fewer decayed teeth in the Xyl-2x group (relative risk, 0.30; 95% confidence interval, 0.13-0.66; P = .003) and in the Xyl-3x group (0.50; 0.26-0.96; P = .04). No statistical difference was noted between the 2 xylitol treatment groups (P = .22).Xylitol oral syrup administered topically 2 or 3 times daily at a total daily dose of 8 g was effective in preventing early childhood caries.

Project description:ObjectiveTo assess the effectiveness of lasers (at sub-ablative parameters) in reducing caries incidence compared with traditional prophylactic interventions (TPIs) when used alone or together with other TPIs such as pits and fissures sealant or fluoride gels or varnishes.DesignA systematic review. Data sources include Medline (via PubMed), Embase, Web of Science and the Cochrane Library (December 2019).Eligibility criteriaOnly randomised trials (RCTs) and controlled clinical trials (CCTs) dealing with prophylactic lasers use (vs TPI or untreated teeth) were considered as eligible. We excluded in vitro and ex vivo studies.Data extractionEligible studies were selected and data extracted independently by two reviewers. Risk of bias was assessed adopting the Cochrane Risk of Bias tool. Data on caries incidence, sealant retention, fluoride uptake, adverse events, treatment duration, patients' discomfort and cost-effectiveness ratio was extracted.Data analysisExtracted data were presented narratively due to the heterogeneity of included studies.ResultsSeven RCTs and two CCTs, all with an evident risk of bias, met inclusion criteria, pooling together 269 individuals and 1628 teeth. CO2, neodymium-doped yttrium aluminium garnet, erbium-doped yttrium aluminum garnet (Er:YAG), erbium, chromium: yttrium scandium gallium garnet (Er,Cr:YSGG) and Argon lasers were used. In the permanent dentition, lasers only when used in combination with TPIs were effective in reducing caries when compared with untreated teeth (risk ratio (RR)=0.44 (0.20-0.97); Er:YAG laser) or with TPIs used alone (RR=0.39 (0.22-0.71); CO2 laser). Moreover, Argon laser significantly improved the fluoride uptake into the enamel surfaces (ANalysis Of VAriance (ANOVA) tests: 95%, p<0.0001). Likewise, sealant retention improved when acid etching was performed on previously irradiated enamel fissures by CO2 laser (RR=0.63 (0.38-1.04)) or Er:YAG laser (RR=0.54 (95% CI: 0.34 to 0.87)). In addition, laser resulted safe and well tolerated by patients.ConclusionDespite some positive indications, an inadequate level of evidence was found in the included studies concerning the lasers' effectiveness in preventing caries. Further studies with a higher methodological quality level are required.

Project description:With the aging of the population, dental caries in the elderly has received increasing attention. A comprehensive study of the oral microbiome is required to understand its polymicrobial etiology. The results of previous studies are limited and remain controversial. In this study, subjects 60 years and older with and without caries were recruited. Unstimulated saliva and dental plaque were collected from each subject and the bacterial 16S rDNA was amplified using PCR and sequenced by Illumina MiSeq high-throughput sequencing. A total of 92 samples were collected from 24 caries patients and 22 healthy controls. Sequences clustered into 147,531 OTUs, representing 16 phyla, 29 classes, 49 orders, 79 families, 149 genera, and 305 species. All predominant phyla, including Proteobacteria, Bacteroidetes, Firmicutes, Fusobacteria, Actinobacteria, and Saccharibacteria, were largely consistent in different groups, but different relative abundances could be observed. The core microbiome was defined with 246 shared species among groups, which occupied 80.7% of all the species detected. Alpha diversity showed no significant differences in bacterial richness or diversity between caries patients and healthy controls, but distinction existed between samples collected from dental plaque and saliva. Beta diversity analysis was performed by PCoA and hierarchical clustering analysis, showing similar results that microorganisms vary between the two niches. The biomarkers of different groups were defined by LEfSe analysis to identify potential caries-related and health-related bacteria. The co-occurrence analysis of the predominant genera revealed significant interactions among oral microbiota and exhibited more complex and aggregated bacterial correlations in caries-free groups. Finally, the functional prediction of the microbiota present in oral samples was performed by PICRUSt, indicating vigorous microbial metabolism in the oral bacterial community. Our study provides thorough knowledge of the microbiological etiology of elderly individuals with caries and is expected to provide novel methods for its prevention and treatment.
