Proteomic analysis of dental pulp from deciduous teeth in comparison to permanent teeth: an in-vitro study.

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
purposeThe aims of this study were to identify proteomic profiles of dental pulp from deciduous teeth and compare the profiles of the two dentitions.
methodsTeeth that were caries-free and had normal pulp conditions were collected from twelve healthy individuals. The obtained teeth consisted of deciduous teeth (n = 6) and permanent teeth (n = 6). Proteins were extracted from pulp tissue and then analysed using liquid chromatography-tandem mass spectrometry. MaxQuant was used to identify and quantify proteins from raw mass spectrometry data of the collected deciduous and previously analysed permanent dental pulp. Differentially expressed proteins (DEPs) between the dental pulp of the two dentitions were identified by a statistical analysis conducted using Metaboanalyst with criteria P-value < 0.05 and fold change > 2.
resultsA total of 3,636 proteins were identified in the dental pulp of deciduous teeth. The biological process functional classifications of these proteins were primarily concerned with cellular process, biological regulation, metabolic process and response to stimulus. Dental pulp protein profiles differed significantly between deciduous and permanent teeth, with 736 proteins being differentially expressed, the majority of which were highly expressed in the pulp of deciduous teeth. Pathway analysis indicated DEPs to be involved in tumour necrosis factor (TNF) signalling, nuclear factor kappa B signalling, and odontoclast/osteoclast differentiation.
conclusionWhile the dental pulp of deciduous and permanent teeth shares some characteristics, there are also significant differences in protein expression, with the TNF signalling pathway and odontoclast/osteoclast differentiation being promoted in the dental pulp of deciduous teeth.
