Moderate mineral loss resultsin a deeper demineralization with some possibility of enamel surface microcavitation, early shallow cavitation, and/or dentin shadowing visible through theenamel, which indicates the likelihood of dentin involvement (for example, microcavitation with visible dentin staining).

Rationale and evidence for the International Caries Detection and Assessment System (ICDAS II). Evidence of lesion activity over time, based on changes (or lack thereof) in the radiolucency (progression or arrest) could have a direct impact on clinical treatment decisions. Br J Psychiatry. The D3 receptor may have a two- to five-times lower affinity for classical neuroleptics, making it unlikely to be the main site of neuroleptic action.

Fast receptor systems, such as the GABAA receptor and the nicotinic receptor at the neuromuscular junction, involve the direct binding of a neurotransmitter to a ligand-gated channel, which opens or closes the channel. The identity and physico-chemical properties of D3, D4, D5, D6 and HMDS are summarised in Table 1 and 2, respectively. Dental caries are a continuum of net mineral loss.
