Frequency of remnants of sealants left behind in pits and fissures of occlusal surfaces after 2 and 3 years.
Trial report in Clinical oral investigations, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThe null-hypothesis tested was that there was no difference in the frequency of remnants of high-viscosity glass-ionomer sealants left behind in pits and fissures of occlusal surfaces of first permanent molars and that of resin composite and glass-carbomer sealants. MATERIALS AND
methodsBased on the results of a sealant trial, a sample of sealed teeth from which the material had apparently completely disappeared from at least one of the three sections into which the occlusal surface was divided, assessed through visible clinical examination, was also assessed from images of colour photographs and Scanning Electron Microscopy (SEM) as the reference image. The sample size consisted of 112 and 120 teeth from 59 and 98 children at evaluation years 2 and 3 respectively. Two examiners performed the assessments. Fisher's Exact Test was applied to test for the differences between the dependent variable and the sealant groups.
resultsThe remnants of sealant material left in the deeper parts of pits and fissures were assessed from colour photograph and SEM images in five sections at year 2 and in eight sections at year 3. The assessment found no sealant group effect.
conclusionThe frequency of remnants of glass-ionomer sealant in pits and fissures of occlusal surfaces in first permanent molars is not higher than the frequency of glass-carbomer and resin sealants after 2 and 3 years. CLINICAL RELEVANCE: Contrary to the current assumption, there appears to be no significant difference in the frequency of remnants left behind in pits and fissures between glass-ionomer and resin sealants.
