Health Promotion & Disease Prevention

Periodontal ligament fibrous attachment of the tooth cementum to alveolar bone
Alveolar process (Alveolar Bone) entire bony entity which surrounds/supports the teeth in each jaw.
Etiology / Pathogenesis The cause, origin, and development of the disease and whether it is acute, chronic or recurrent.
Acquired pellicle An acellular, translucent, homogeneous, thin, unstructured film composed of salivary glycoproteins that closely & firmly adheres to surfaces of the oral cavity.
Attached Plaque A type of plaque that is located in the subgingival area. Associated with calculus formation, root caries, & resorption.
Plaque/Biofilm Invisible, transparent, white film accumulated on the tooth surface
Loosely attached plaque A type of plaque that is located between the two layers of attached biofilm in the subgingival area. It consists of planktonic, motile, & gram negative "free floating" organisms.
food debris Food particles along gingival margin between teeth & around crowded teeth
Calculus / Tartar Calcified plaque
Materia alba Loosely adherent complex of bacteria and cellular debris. Looks like cottage cheese.
Stain Discolored spot or area on a tooth
Extrinsic Stain Occur on external surface of a tooth and removable by polishing (Tea, Coffee)
Intrinsic Stain Occur within tooth structure and not removable by polishing(Meds)
Exogenous Develop or originate from sources outside the tooth and may be extrinsic or intrinsic.(Cigarettes)
Endogenous develop or originate from within tooth and are always intrinsic. (results from Trauma, Tetracycline)
4 classifications of stains Extrinsic, intrinsic, exogenous, endogenous
Yellow Stains 1.has a clinical appearance- dull yellow 2.caused by discoloration of the accumulation of dental plaque 3.is the most common type stain and is associated with poor oral hygiene.
Tobacco Stain second most common extrinsic stain; has a clinical appearance which varies from yellow to almost black; may occur any where in mouth and usually is embedded within plaque and calculus.
Subgingival Calculus formations(4) SPICULE "fine,grainy" / NODULE "bump" / LEDGE "ringlike,dense & heavy" / VENEERS "thin,smooth"
Burnished Calculus Residual calculus not removed by the clinician or instrumentation following SRP
Can some extrinsic stains (green or tobacco) become embedded & become intrinsic? yes
Chromogenic bacteria Pigment producing bacteria (Staphylococcus aureus — Golden yellow pigment)
supragingival On the crown coronal to the gingival margin
subgingival On the tooth structure and found apical to the gingival margin of the periodontal pocket.
Periodontium Comprises the root cementum, the periodontal ligament, & alveolar bone.
Sulcus Shallow groove b/t the free gingiva and the surface of a tooth and extending around its circumference.
Pocket Deepen sulcus, inflammation with edema, may cause bone loss & detachment from PDL.
Free gingiva The portion of the gingiva that surrounds the tooth and is not directly attached to the tooth surface.
Attached gingiva The portion that is firm, resilient, and bound to the underlying cementum and alveolar bone.
Junctional epithelium A circular arrangement of epithelial cells occurring at the base of the gingival sulcus and attached to both the tooth and the subepithelial connective tissue.
Cementum A bonelike substance covering the root of a tooth
Periodontitis Disease of the periodontium characterized by inflammation of the gums, resorption of the alveolar bone, and degeneration of the periodontal membrane. Condition irreversible, bone loss
Gingivitis nflammation of the gingiva, with symptoms that may include erythema, edema, and bleeding. Condition reversible, no bone loss.
