1 · What the graph read from it

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.

2 · The registry

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

objectivesVitamin D deficiency is associated with a variety of oral health disorders. The aim of the present cross-sectional study was investigate the association between parental-reported vitamin D supplementation and oral health in 6- and 10-year-old children living in Poland. MATERIAL AND

methodsThe study population consisted of 2019 6- and 10-year old children from 10 out of 16 provinces in Poland. Parents answered a structured questionnaire covering information on socio-economic and dietary factors as well as data on the oral hygiene behavior. The children underwent a clinical examination and the prevalence of dental caries and frequency (dmft/DMFT) and gingival bleeding on probing (BOP) was recorded. We used Spearman's correlation and logistic regressions to calculate associations between vitamin D supplementation and the collected data.

resultsAccording to the parents, 44.3% of the 6-year olds and 32.7% of the 10-year-olds received vitamin D supplements. For both age groups combined, the prevalence of dental caries (dmft/DMFT>0) was 84.0%. BOP was recorded in 15.5% and 27.8% of the 6- and 10 year olds, respectively. The multiple logistic regression analyses indicated that vitamin D supplementation was significantly associated with a reduced risk of gingival bleeding (OR 0.34; 95% CI: 0.12; 0.56) but we found no association with the prevalence or frequency of caries in the mixed dentition.

conclusionVitamin D supplementation was associated with better gingival health in children but we found no caries-preventive effects in the mixed dentition. CLINICAL RELEVANCE: Vitamin D supplements are important and do more good than harm, in particular among children living in the Northern hemisphere. Our study showed that Vitamin D supplementation is associated with better gingival health in schoolchildren. The association between vitamin D supplementation and dental caries is still probable but definitely not clear and we found no caries-preventive effects in the mixed dentition. Therefore we encourage further controlled clinical trials on this matter with focus on the mixed and young permanent dentitions.
