Cytotoxicity and Genotoxicity of Resin-Based Dental Composites Modified with Quaternary Ammonium Salts.

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
The primary reason of dental restoration failure is the recurrence of caries, driving research to incorporate quaternary ammonium salts (QASs) into resin-based composites (RBCs). Given the prolonged contact of these materials with oral tissue, this in vitro study assessed the biocompatibility (cytotoxicity and genotoxicity) profiles of experimental RBCs modified with cetyltrimethylammonium bromide (CTAB) and dimethyldioctadecylammonium bromide (DODAB), using two restorative materials: an unmodified-experimental composite, KE, and Flow-Art (FA) as comparative standards. The primarily novelty of this study is the direct comparison of the cellular safety profiles of CTAB vs. DODAB when incorporated into RBCs. Human fibroblast BJ cells were exposed to composite eluates for 24 h, and cell viability (MTT assay), the percentage of apoptotic and necrotic cells (the Annexin V/Propidium Iodide (PI) flow cytometry method), and DNA damage (the alkaline comet assay) were quantified. Among the compounds evaluated, only CTAB caused a significant, dose-dependent decrease in BJ cell viability, primarily by inducing late apoptosis or necrosis. Cell viability was severely reduced, dropping by 84% at 2 wt% CTAB (
