1 · What the graph read from it

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.

2 · The registry

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

Kombucha is a fermented, sweet and acidic beverage, belonging to the functional beverage market. This study aimed to evaluate the erosive potential of Kombucha against dental hard tissues using an erosion/abrasion (EA) cycling promoted by a new laboratory multifunctional oral cavity simulator (MOCS). This in vitro study used a preclinical simulator to evaluate surface loss (step height) in bovine enamel and dentin specimens. The study design comprised two brands of Kombucha commercially available in the Brazilian market (experiment 1, DÊVI Kombucha; experiment 2, Tao Kombucha), three groups (negative control/water; positive control/Coca-Cola; test group/Kombucha), and two teeth substrates (enamel and dentin), with nine specimens per group (108 in total). The EA cycling consisted of exposure 3x/day for 10 min to the solutions (0.25 mL/min); toothbrushing (abrasion) 2x/day with fluoridated dentifrice (NaF; 1100 ppm) and with a soft bristle toothbrush; constant flow of artificial saliva during the day (0.2 mL/min) and overnight (0.04 mL/min). After 5 days of EA cycling, dentin/enamel surface loss/step height was measured by optical profilometry. Regarding the tested Kombuchas, DÊVI induced less surface loss than Coca-Cola, whereas the surface loss induced by Tao and Coca-Cola was similar. All tested drinks induced greater surface loss than the negative control. Among the substrates, surface loss was lower in dentin. In conclusion, this study demonstrated that the Kombuchas tested may have erosive potential causing significant loss of tooth structure. The regular consumption of Kombucha might expose dental hard tissues to an increased risk for erosive tooth wear.
