Question | Answer |
---|---|
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. |
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. |
