Salivary cortisol: Biomarker for stress during routine dental extractions - A prospective comparative study.
Article in Bioinformation, 2026. 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
Dental procedures, including routine extractions, can induce psychological stress and activate the hypothalamic-pituitary-adrenal axis (HPAA), leading to increased cortisol levels. Therefore, it is of interest to evaluate salivary cortisol as a biomarker of stress in 15 healthy male patients aged 30-50 years undergoing simple extraction of single-rooted teeth. Saliva samples were collected 30 minutes before and 30 minutes after the procedure between 10:00 AM and 2:00 PM to minimize diurnal variation and cortisol levels were estimated using enzyme-linked immunosorbent assay. The mean salivary cortisol level increased significantly from 19.27 ± 10.27 ng/mL before extraction to 51.27 ± 10.75 ng/mL after extraction (paired t-test, p < 0.001). Thus, we show that salivary cortisol is a reliable non-invasive biomarker for assessing acute stress associated with routine dental extractions.
