OXYGEN DELIVERY SYSTEMS: for the administration of oxygen accessories like supplemental oxygen delivery device, nasal cannulae, nonrebreathing mask with oxygen reserviour, nasal hood, a portable oxygen cylinder with a regulator, bag-valve mask device with oxygen reservior, forceps, oropharangeal airways should be available.
DRUGS: local and general anesthesia, nitrous oxides, intravenous sedations are used in dental operations to control pain. Other commonly used pain relievers include anti- inflammatory drugs, acetoaminophen or tylenol, anesthetics and topical analgesics.
A suitable drug preparation should be available keeping in mind the age and health of the patient.
