Determination of streptococcus mutans retention in acidic and neutral pH artificial saliva environment of all-ceramic materials with different surface treatment.
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 4 papers.
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
backgroundAlthough surface finishing processes are effective against Streptococcus mutans biofilm, the mechanism of action of saliva with different acidity values has not been studied in detail. This study aims to produce four different all-ceramic materials in a single session with CAD/CAM devices and apply two different surface finishing processes, glazing and polishing, and then determine the retention of Streptococcus mutants on the surfaces of the materials in saliva with varying levels of acidity.
methodsZirconia-reinforced lithium silicate (Vita Suprinity, Vita Zahnfabrik, Bad Saöckingen, Germany), monochromatic feldspar (Vitablocs Mark 2, Vita Zahnfabrik, Bad Saöckingen, Germany), leucite glass ceramic (IPS Empress CAD, Ivoclar Vivadent, Liechtenstein), and monolithic zirconia (Incoris TZI (Cerec) Sirona, Germany) were used in the study. The surface roughness values of all samples were measured with a profilometer before the application of S. mutans biofilm. A modified Fusayama artificial saliva model was prepared to reflect the oral environment. S. mutans bacterial biofilm growth rate was determined for each group with tetrazolium dye (MTT) assay and the colony-forming unit (CFU/mL). Scanning electron microscopy was used to compare the efficacy of all-ceramic materials against bacterial biofilm.
resultsThe surface treatment applied with polishing rubber (Ra 0.18-0.33) resulted in a slightly less rough surface than the glaze (Ra 0.32-0.35) treatment. S. mutans showed less retention in ceramic samples treated with the pH 5 saliva compared to the pH 7 ones. When this group's percentage growth rates, colony-forming units, and scanning electron microscopy images colored with ImageJ were examined, the Glaze application reduced growth (65.02 - 91.38%) and colony formation (6.1 × 10
conclusionThe pH of the salivary, the surface roughness, and the chemical content of the ceramic samples may directly affect the S. mutans biofilm formations. The Polishing Rubber of the surface treatment type should only be suggested for Vita Suprinity, whereas the Glaze of the surface treatment type should be proposed for Vita Block Mark II and InCoris TZI in an acidic salivary environment. A surface treatment method other than Glaze and Polishing Rubber should be preferred for IPS Empress CAD.
