SKULL.
The skull consists of 28 bones, 22 of which form the framework of the head and provide protection for the brain, eyes, and ears; six are ear bones. With the exception of the lower jaw bone and the ear bones, all skull bones are joined together and fixed in one position. The seams where they join are known as sutures. The bones of the skull are classified as either cranial or facial bones.
Cranial Bones.
The cranium is formed by eight major bones, most of which are in pairs. The frontal bone forms the forehead and the roof of each orbit (or eye socket) and the nasal cavity. The parietal bones form the roof of the skull. The temporal bones help form the sides and base of the skull and also house the auditory and hearing organs. The occipital bone forms part of the base and back of the …show more content…
Protective eyewear protects the mucous membranes of the eyes from contact with microorganisms. Protective eyewear for patients also can protect their eyes from spatter or debris generated during dental procedures. Reusable protective eyewear should be cleaned with soap and water, and when visibly soiled, disinfected between patients.
Clothing
Various types of protective clothing (e.g., gowns, jackets) are worn to prevent contamination of street clothing and to protect the skin of personnel from exposure to blood and body fluids. When the gown is worn as personal protective equipment (i.e., when spatter and spray of blood, saliva, or other potentially infectious material is anticipated), the sleeves should be long enough to protect the forearms. Protective clothing should be changed daily or sooner if visibly soiled. Personnel should remove protective clothing before leaving the work area.
