chapter 16 Flashcards
serves to anchor, support, and protect the teeth
periodontium
structures that anchor the tooth in the alveolar socket
Periodontal (peri-odont-al) tissues/ligaments
bony socket in which teeth are located
Alveolar (alveo/l-ar) tissue
the gum tissue that surrounds the tooth to protect the tooth root and the underlying tissues
Gingiva
structure that covers the whole root
Cementum
gingival tissues react to the build-up of plaque
Dental plaque involvement
the gums react to dental plaque more intensely due to internal factors such as pregnancy or malnutrition
Dental plaque with systemic involvement may be called induced gingivitis
gingivitis secondary to causes other than plaque. An example would be a bacterial infection
Non-dental plaque lesions
gingivitis is secondary to allergic responses to extrinsic factors, such as certain foods
Allergies
the gingivae become inflamed as a result of an injury
Trauma
inflammation that progresses slowly and is a long-term problem
Chronic periodontitis
rapid loss of periodontal tissue and bone destruction, usually the result of bacteria
Aggressive periodontitis
loss of periodontal tissue despite optimal oral hygiene and patient compliance
Refractory periodontitis
peridontium is inflamed secondary to other diseases or disorders, such as malnutrition, AIDS
Periodontitis due to systemic disease
rapidly progressing diseases where the tissue cells become necrotic (irreversible cell death). May affect the gingivae only (necrotizing ulcerative gingivitis), or may involve other periodontal tissues as well (necrotizing ulcerative periodontitis)
Necrotizing periodontal diseases
redness
Erythema
swelling
Edema:
Common signs of periodontal disease stippling is the ‘speckling of fine dots’ seen on the tissues. When this stippling is lost, the tissues become sleek and shiny
Stippling loss
as the gums begin to recede, tooth root surfaces can be seen
Pocket formation
foul-smelling fluid or semi-solid discharge
Exudate
teeth become loose and more mobile due to lack of anchoring and support
Tooth mobility
scaling and removal of plaque, calculi (tartar, plural of calculus), and other irritants from the gingivae
Periodontal debridement
removing stains and other irritants from the teeth
Tooth polishing
individualized instructions for optimal home hygiene, might include antibacterial (anti-bacteri-al) agents, mouth rinses, improved food choices
Patient education
cutting into the mucous membranes to correct the shape or position of the gingivae, or to ease the swelling caused by pericoronitis
Mucogingival excision
refers to inflammation of the gums around the crown of an erupting tooth
pericoronitis
portion of tissue is detached from the underlying alveolar bone to allow for drainage of exudate or other irritants, and to allow for elimination/removal of deposits
Periodontal flap
involving the alveolar bone to alter its anchoring of the tooth, thereby altering the gingival tissues around the tooth
Osseous surgery
