Synthesis of an experimental gel containing cannabidiol oil and evaluation of effects on bleached bovine enamel.
Article in Odontology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07027566 (Effect of an Experimental Cannabidiol Gel on Tooth Sensitivity Induced by Tooth Bleaching), which is not on this map. Cited by 1 paper.
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.

Abstract
To obtain and characterize a gel containing cannabidiol (CBD) oil using Fourier transform infrared spectroscopy, high-performance liquid chromatography (HPLC), thermogravimetry, and differential scanning calorimetry, and to evaluate its effects on color change (∆E00), surface roughness (Ra), Knoop microhardness (KHN), ultrastructure, and mineral content in bovine enamel after bleaching with 35% hydrogen peroxide (HP35%). For HPLC, diluted CBD oil was used, UV spectra were obtained in the range of 4000-650 cm - 1 with a resolution of 4 cm - 1, and for thermal profile determination, CBD oil and the gel were heated from 20 to 300 °C. To evaluate the effects on bovine dental enamel, 40 specimens were distributed into 4 groups (n = 10): control-untreated; HP35%-bleaching with HP35%; KF2-5% potassium nitrate and 2% sodium fluoride + HP35%; CBD-CBD gel + HP35%. The bleaching treatment was performed in 3 sessions with a 72 h interval. Desensitizers were applied for 10 min prior to bleaching. Results were evaluated by one-way ANOVA and Tukey test (p < 0.05). Analyses demonstrated a satisfactory profile for the use of CBD gel. All treated groups showed significant bleaching effect, and there was no difference among them regarding ∆E00, Ra, and KHN. The experimental CBD gel proved to be safe when used prior to the bleaching agent, as it did not influence the effectiveness of bleaching, surface roughness, microhardness, and mineral content of bovine dental enamel.
