To diagnose class III caries clinically, which is caries that involves the proximal surfaces of teeth, a good supplement to radiographs is to examine the proximal surfaces for any color changes, particularly at the contact points where two teeth touch. This is often done using a combination of visual inspection and the use of a dental explorer to detect cavities and softened enamel. However, the answer provided, "Caries activity tests," refers to methods used to assess the activity or inactivity of a caries lesion, not necessarily for diagnosis.

The liquid phase of a denture base resin primarily consists of nonpolymerized methyl methacrylate (monomer) and a cross-linking agent like glycol dimethacrylate.

If freeway space is obliterated, it would result in all of the above: improper aesthetics, clicking sounds of the dentures, trauma to the underlying ridges.

Sudden death in acute myocardial infarction is most commonly due to ventricular fibrillation. This lethal arrhythmia results from electrical instability of the ischemic myocardium and accounts for approximately 50% of deaths in the first hour after MI onset.

Endorphins, particularly ?-endorphin, are opioid peptides that act as natural painkillers. They are released during stress and pain and bind to opioid receptors in the brain and spinal cord to inhibit the transmission of pain signals. While they do have secondary effects on mood and stress response, their primary function is pain inhibition.

When replacing all missing maxillary incisors with PFM restorations, both canines and first premolars should be used as abutments. The four missing incisors create a large span requiring additional support beyond just the canines. Including the first premolars provides better force distribution, stability, and reduces stress on individual abutments, improving long-term prognosis.
