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

To better understand the nature of the relationships between mineral phases at the dentino-enamel boundary (DEB), we performed electron tomography (ET) and high-resolution transmission electron microscopy (HR-TEM) of the apical portions of rat incisors. The ET studies of the DEB at the secretory stage of amelogenesis revealed that nascent enamel crystals are co-aligned and closely associated with dentin crystallites in the mineralized von Korff fibers, with the distances between dentin and enamel crystals in the nanometer range. We have further studied the relationships between dentin and enamel crystals using HR-TEM lattice imaging of the DEB. Among dozens of high-resolution micrographs taken from the DEB we were able to identify only one case of lattice continuity between dentin and enamel crystals, indicating direct epitaxy. In other cases, although there was no direct continuity between the crystalline lattices, power spectra analysis of lattice images revealed a very high level of co-alignment between dentin and enamel crystals. Hence, we propose here that the high degree of alignment and integration between dentin and enamel mineral can be established either by epitaxy or without direct interactions between crystalline lattices, probably via regulation of mineral formation and organization by integrated organic matrices of dentin and enamel at the DEB.
