Fluoride does not inhibit enamel protease activity.
Article in Journal of dental research, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Fluorosed enamel can be porous, mottled, discolored, hypomineralized, and protein-rich if the enamel matrix is not completely removed. Proteolytic processing by matrix metalloproteinase-20 (MMP20) and kallikrein-4 (KLK4) is critical for enamel formation, and homozygous mutation of either protease results in hypomineralized, protein-rich enamel. Herein, we demonstrate that the lysosomal proteinase cathepsin K is expressed in the enamel organ in a developmentally defined manner that suggests a role for cathepsin K in degrading re-absorbed enamel matrix proteins. We therefore asked if fluoride directly inhibits the activity of MMP20, KLK4, dipeptidyl peptidase I (DPPI) (an in vitro activator of KLK4), or cathepsin K. Enzyme kinetics were studied with quenched fluorescent peptides with purified enzyme in the presence of 0-10 mM NaF, and data were fit to Michaelis-Menten curves. Increasing concentrations of known inhibitors showed decreases in enzyme activity. However, concentrations of up to 10 mM NaF had no effect on KLK4, MMP20, DPPI, or cathepsin K activity. Our results show that fluoride does not directly inhibit enamel proteolytic activity.
