Acceptable daily intake or ADI is a measure of the amount of a specific substance originally applied for a food additive , later also for a residue of a veterinary drug or pesticide in food or drinking water that can be ingested orally on a daily basis over a lifetime without an appreciable health risk. An ADI value is based on current research, with long-term studies on animals and observations of humans. First, a no-observed-adverse-effect level NOAEL , [3] [4] the amount of a substance that shows no toxic effects, is determined.
The atlantodental interval ADI , as the name suggests, is the horizontal distance between the anterior arch of the atlas and the dens of the axis , used in the diagnosis of atlanto-occipital dissociation injuries and injuries of the atlas and axis. It is the distance in mm between the posterior cortex of the anterior arch of the atlas and the anterior cortex of the dens in the median midsagittal plane.
