When replacing all missing mandibular incisors with PFM restorations, both canines should be used as abutments.

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.
