Effect of ibuprofen on amelogenesis in Wistar rats.
Article in Journal of applied oral science : revista FOB, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThis work aimed to evaluate the effect of ibuprofen on amelogenesis using a model of continuously growing incisors in Wistar rats. METHODOLOGY: A total of eight female Wistar rats at weaning age were assigned to one of two groups (IBU and control). They were administered an 80 mg/kg dose of ibuprofen or an equivalent volume of distilled water for three weeks, then euthanized on day 16 of the experiment. Right hemimandibles were used to assess the mineral density of enamel using microtomography. The left hemimandibles were decalcified and processed to obtain sections, stained with Hematoxylin Eosin or immunohistochemical detection of amelogenin. Based on photomicrographs of hemimandibles, ameloblast and papillary layer height of the enamel and enamel organic matrix width were determined. The percentage of positive amelogenin was determined in immunohistochemically processed sections. Results were analyzed using Student's t test.
resultsIBU-treated animals showed lower body weight gain throughout the experiment (p<0.05). Mineral density and enamel thickness showed no significant differences. No significant differences in the height of the papillary layer or the width of the organic matrix were observed. Amelogenin expression in the ameloblast layer was lower in the experimental group. No significant difference was found between groups.
conclusionThe results obtained in this study model suggest that ibuprofen itself might not alter the amelogenesis process.
