Effects of maternal morphine consumption on odontogenesis in rats: A histomorphometric study.
Article in Journal of dental research, dental clinics, dental prospects, 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
Background: Extensive research has established the adverse impact of morphine sulfate addiction on the central nervous system. Additionally, studies have shown that the consumption of morphine during pregnancy can impair normal fetal development. This study examined the influence of morphine sulfate on tooth development in rats. Methods: Thirty female Wistar rats were randomly assigned to two groups. The experimental group was given morphine sulfate at a final dose of 0.4 mg/mL, while the control group received only water. Dependence on morphine was verified through the use of naloxone. We examined the effect of morphine sulfate on the development of maxillary first molars in rat embryos on day 19 of gestation, as well as on days 1, 4, 7, and 10 after birth. Two or three rats were separated from each mother and anesthetized using ketamine at 2 mg/kg. Thin sections were prepared from paraffin blocks of the tissue and stained with hematoxylin and eosin. Statistical analyses were conducted with SPSS 20 using ANOVA and post hoc Tukey tests ( Results: Research findings indicated that, on the first day after birth, the enamel organ had a significantly greater thickness in the control group ( Conclusion: These results suggest that morphine sulfate interfered with the development of the tooth bud and reduced the secretion of enamel and dentin matrix.
