Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.

ElementPlanned (methods)Found (results)
PopulationChildren or adolescents aged 16 or less at the start of the study, irrespective of initial dental caries level, background fluoride exposure, dental treatment level, nationality, setting or start time; studies selecting participants on the basis of special (general or oral) health conditions were excluded144 trials involving over 65,000 children (65,169 in the 133 D(M)FS meta-analysis trials); most conducted in industrialized countries (USA, UK, Europe, Scandinavia), at least 14 elsewhere; studies generally large (only 15 allocated fewer than 100 children), nearly all recruited from schools; trials conducted 1954 to 1996
InterventionTopical fluoride therapy in the form of toothpastes, mouthrinses, gels or varnishes only, using any fluoride agent (any compatible abrasive system for toothpastes), at any concentration (ppm F), amount or duration of application, with any technique/method of application; frequency of application at least once a yearFluoride toothpaste (n=74); Fluoride mouthrinse (n=36); Fluoride gel (n=25); Fluoride varnish (n=9)
ComparisonPlacebo (for any method of fluoride application) or no treatment (except for brushing or flossing methods of application)Placebo (n=125); No treatment (n=19)
OutcomesPrimary: caries increment measured by change from baseline in D(M)FS (permanent) and d(e/m)fs (deciduous). Also relevant: coronal caries and fillings in permanent and deciduous dentitions; tooth loss; proportion of children developing new caries; dental pain/discomfort; specific side effects (fluorosis, tooth staining/discoloration, oral allergic reactions, adverse symptoms such as nausea/vomiting); unacceptability of treatment (dropouts); use of health service resourcesD(M)FS increment (n=133); D(M)FT increment (n=79); d(e/m)fs increment (n=5); Proportion of children developing new caries (n=13); Unacceptability of treatment/drop outs (n=10)
Study designsRandomised or quasi-randomised controlled trials using or indicating blind outcome assessment, comparing one form of TFT (toothpaste, mouthrinse, gel or varnish) concurrently to a placebo or no TFT group for at least 1 year/school year; split-mouth/within-group paired designs, open outcome assessment, and trials under 1 year were excludedAll randomised or quasi-randomised parallel-group trials (109 described as randomised without adequate detail, 21 quasi-randomised; 118 double-blind, 14 single-blind, 12 blinding indicated); 2 cluster-randomised trials; 5 trials contributed no data for meta-analysis
TimingAt least 1 year/school yearStudy duration ranged from 1 to 6 years (great majority 2 or 3 years); trials conducted between 1954 and 1996 (three in the 1950s, most in the 1960s-1970s, 16 in the 1980s, four in the 1990s)
