The hinge axis face bow specifically records the kinematic hinge axis of the mandible and the three-dimensional position of the maxilla in relation to this axis. This information is crucial for accurately mounting the casts on an articulator, which simulates jaw movements.

Delirium and convulsions are not a characteristic feature (contrast barbiturates) and are seen only occasionally.

Cardi-ovascular collapse and fatality are rare if supportive measures are instituted.

Proper hand washing is considered the single most effective method for preventing the spread of infections, especially in healthcare settings like intensive care units. It is a fundamental practice of hygiene that removes transient microorganisms from hands, thus breaking the chain of cross-infection between patients or between healthcare workers and patients. Giving antibiotics to all other patients (A) would contribute to antibiotic resistance and does not address the primary mode of transmission. Fumigating (B) or disinfecting with sodium hypochlorite (C) the entire ward are measures for environmental decontamination, which are less effective than hand hygiene in preventing direct person-to person or indirect transmission via contaminated hands or equipment.

 In anterior teeth, "rests" are ideally prepared and located on the lingual surfaces. This is because the lingual surfaces provide better support for the denture and distribute the occlusal forces more evenly across the palatal mucosa, reducing the risk of denture movement and discomfort.

The toxins produced by Clostridium difficile cause ribosylation of small GTPases like Rho, leading to disruption of the actin cytoskeleton, increased cytokine release, and epithelial cell apoptosis, which in turn results in the formation of pseudomembranes and the symptoms of pseudomembranous colitis.
