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

purposeDifferences in enamel density and thickness influence caries risk, emphasising their role in targeted early childhood caries (ECC) prevention. This study aims to compare the enamel thickness and density of unaffected enamel in primary teeth with ECC to that of caries-free (non-ECC) primary teeth using micro-computed tomography.

methodsA total of 128 primary teeth were analysed and divided into two groups: Group I (unaffected surface of the enamel of primary teeth with ECC) and Group II (healthy teeth). Enamel thickness and density of healthy surfaces of both groups were measured using a μCT 100 system, and differences between groups were statistically evaluated using the Mann-Whitney U test.

resultsEnamel thickness was significantly higher in Group I (0.973 mg HA/ccm) compared to Group II (0.553 mg HA/ccm), with a statistically significant difference (p = 0.001). The mean enamel density in Group I was 2255.75 µm compared to 2294.71 µm in Group II (p = 0.001). In both the maxilla and mandible, Group II (healthy teeth) surfaces had higher enamel density (p = 0.001), whilst enamel thickness showed no significant difference. Amongst anterior teeth, Group II teeth surfaces exhibited significantly higher enamel density (p = 0.003).

conclusionEnamel density, more than enamel thickness, emerges as a key indicator of ECC risk, enabling paediatric dentists to more accurately predict and identify vulnerable tooth surfaces before the onset of visible caries.
