The effects of cola consumption on tooth discoloration among dentistry university students.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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 AND
aimCarbonated drinks are popular beverages among the general population, including dental students. These drinks, such as Coca-Cola, contain high levels of sugar and acidic components, which can contribute to tooth discoloration. This cross-sectional in vivo study was designed to measure the impact of cola consumption on the colour change of the upper anterior six teeth in dentistry students. The objective was to assess colour changes exclusively. This study aimed to evaluate the discoloration on the anterior surface of anterior teeth of dentistry university students after one month of Cola consumption in different consumption groups. MATERIALS AND
methodsA cross-sectional study was conducted among first and second-year dental students (N:64). The upper six anterior teeth, including both canines, of each of the 64 students were measured by spectrophotometer, with three measurements taken to record L, a, b, C, H values per tooth region and the averages recorded. After one month of Coca-Cola consumption, the color measurements of these teeth were repeated.
resultsCola consumption significantly impacted tooth discoloration among dentistry students. Anterior teeth in high-consumption groups showed greater color changes (p < 0.05) across L, a, H, Delta L (ΔL), Delta a (Δa), Delta H (ΔH), Delta E (ΔE) and Delta E
conclusionThe findings suggest that Coca-Cola consumption is common among dental students and may be associated with tooth discoloration. This highlights the importance of oral health education and preventive measures among dental students to minimize the risk of tooth discoloration associated with carbonated drink consumption.
