UNASSIGNED: Data sourcesCochrane Oral Health Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), Medline, Embase, CINAHL, Web of Science Conference Proceedings, Proquest Dissertations and Theses, US National Institutes of Health Trials Register (http://clinicaltrials.gov) and the WHO Clinical Trials Registry Platform for ongoing trials. No language or year restrictions were used.Study selectionRandomised controlled trials assessing the effects of @entity8372 products on dental @entity1547 in @entity1 and adults.Data extraction and synthesisTwo review authors independently screened the results of the electronic searches, extracted data and assessed the risk of bias of the included studies. Authors were contacted where possible for missing data or clarification where feasible. For continuous outcomes, means and standard deviations were used to obtain the mean difference and 95% confidence interval (CI). Continuous data was used to calculate prevented fractions (PF) and 95% CIs to summarise the percentage reduction in @entity1547 . For dichotomous outcomes, reported risk ratios (RR) and 95% CIs were used. As there were fewer than four studies included in the meta-analysis, a fixed effect model was used.ResultsTen studies were included with a total of 5903 @entity1 . One study was assessed as being at low risk of bias, two were assessed as unclear risk of bias with seven at high risk of bias. Over 2.5-3 years, low quality evidence demonstrated that with 4216 @entity1 analysed, a @entity1388 toothpaste with 10% @entity8372 (exact dosage unsure) reduced @entity1547 by 13% when compared to a @entity1388 only toothpaste. (PF -0.13, 95% CI -0.18 to -0.08. Remaining evidence of the use of @entity8372 in @entity1 has risk of bias and uncertainty of effect and was therefore insufficient to determine a benefit from @entity8372 . Four studies reported that there were no adverse effects from any of the interventions. Two studies reported similar rates of adverse effects between study arms. The remaining studies either mentioned adverse effects but did not report any usable data, or did not mention them at all. Adverse effects include sores in the mouth, cramps, bloating, @entity1142 , flatulence and loose stool or @entity294 .ConclusionsLow quality evidence suggested that @entity1388 toothpaste containing @entity8372 may be more effective than @entity1388 -only toothpaste for preventing @entity1547 in the permanent teeth of @entity1 . The effect estimate should be interpreted with caution due to high risk of bias and the fact that it was derived from two studies that were carried out by the same authors in the same population. The remaining evidence was low to very low quality and is insufficient to determine whether any other @entity8372 -containing products can prevent @entity1547 in @entity1 , older @entity1 or adults.
