Investigating the Effect of Vitamin A on Orthodontic Tooth Movement: An Experimental Study.
Article in Combinatorial chemistry & high throughput screening, 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
backgroundVitamin A is essential not only for bone metabolism and development but also for the normal functioning of many physiological processes in the body. Despite vitamin A's important involvement in bone metabolism, its effect on orthodontic tooth movement is not entirely known.
aimPrevious studies on animals have suggested that vitamin A may influence alveolar bone remodelling and tooth movement, but the effect of various doses of vitamin A on these processes remains poorly understood. This experiment was designed to examine the effect of vitamin A on the orthodontic tooth movement of male rats.
methodsEighty male rats weighing 200-250 grams were divided into eight equal parallel groups. An initial orthodontic force was applied to all groups with a specific appliance, and six different doses of vitamin A were administered (250-2500 IU/Kg intraperitoneally). Two control groups were also considered. Orthodontic tooth movement was measured at the beginning and end of the study period (day 14), and serum alkaline phosphatase (ALP) level was evaluated. The maxillary sections were also evaluated by histological examination.
resultsAlthough there was a dose-dependent increase in tooth movement observed with vitamin A administration, the differences were not statistically significant. There was no significant difference in the number of osteoclasts or the presence of lacunae on the root surface between the study groups. Root resorption was observed in different areas of the root and was not related to different doses of vitamin A. The serum ALP level did not show any significant difference between the groups treated with different doses of vitamin A.
conclusionDespite the known effects of vitamin A on bone metabolism, the results of this study suggest that vitamin A did not increase alveolar bone remodeling and orthodontic tooth movement in male rats.
