Probing Force 2. Inflammation Ideal probing force - ANSWER-20g Recession - ANSWER-Distance from CEJ to Marginal Gingva (Recession = Attachment Loss) 3 Causes of Recession PMT - ANSWER-Trauma Malposition (Genetic/Iatrogenic) Periodontal Disease What is Attachment Loss? - ANSWER-Distance from CEJ to pocket BASE Pocket Depth + Recession = Attachment Loss What are 2 Types of Cementum? - ANSWER-Acellular - 윗 2/3, contains mostly "Sharpey's Fibres" Cellular - 밑 1/3 Mobility (how many degrees?) MD - ANSWER-Degree 0 - normal movement Degree 1 - Tooth moves 0.2-1 mm Horizontally Degree 2 - Tooth moves 1-2 mm Horizontally Degree 3 - Tooth moves >2 mm Horizontally (can rotate and depressed in pocket) Furcations (FD) - ANSWER-Upper Molars 3 Sites Upper 1st Premolar 2 Sites Lower Molars 2 Sites Degree 1 - 1/3 width Degree 2 - greater than 1/3 but not through Degree 3 - Horizontal "through" 3 Causes of Gingivitis - ANSWER-Plaque Risk Factors (Local & Systemic) Medication 3 Types of Necrotizing Peridontal Disease? What are the extent? - ANSWERNecrotizing Gingivitis - no attachment loss Necrotizing Periodontitis - yes attachment loss Necrotizing Stomatitis - progressed beyond mucogingival junction What are "Stages" and "Grades" in Perio - ANSWER-Stage: based on Severity and Complexity & Extent/Distribution (Localized, Generalized, Molar-Incisor) Grade: based on "Risk of progression" and "anticipated Response of Treatment" (ex. smoking) What is "Localized" perio - ANSWER-less than 30 % of teeth affected What are the 3 Stages of "Grade" - ANSWER-A: Slow progression B: Moderate progression C: Fast progression How do you identify "Periodontitis" case in Clinical setting - ANSWER-1. Interdental AL found at more than 2 non-adjacent teeth 2. Buccal AL found greater than 3mm w/ pocket deeper than 3mm @ more than 2 teeth Criteria for "healthy" gingiva - ANSWER-No attachment Loss No bone loss (maybe) less than 3mm PD less than 10% BOP Periodontitis - Staging: How do you define "Severity" - ANSWER-Interdental AL Radiographic Bone Loss Tooth Loss Periodontitis - Staging: How do you define "Complexity" - ANSWER-Local assessment - Horizontal Bone Loss, Maximum PD (Vertical BL, Furcation, Mobility, Remain teeth number etc) Periodontitis - Stageing: "Extent and Distribution" How do you define? - ANSWERLocalized (less than 30%) General (more than 30%) Incisor-Molar Distribution Periodontitis - "Grading": What are the Primary criteria? - ANSWER-Direct evidence of Progression (radiographic bone loss or CAL) Indirect evidence of Progression (% Bone Loss/Age & Case Phenotype - ex. biofilm deposits) Periodontitis - "Grading": What are the Risk Factors? - ANSWER-Smoking Diabetes What are the characteristics of Necrotising Gingivitis? - ANSWER-"Ulerated Papilla" (ALWAYS LOOK AT PAPILLA FIRST) "Marginal gingiva has punched out appearance" "Pseudomembrane" What are the characteristics of Necrotising Periodontitis? - ANSWER-"Papilla Cratering - papilla가 없어짐" "AL and Bone Resorpion" What are the characteristics of Necrotising Stomatitis? - ANSWER-"Severe bone/tissue destruction" "Swelling of lymph nodes" "related to severe immune compromise" Treatments of Necrotising Gingivitis - ANSWER-Debridement Chemical Plaque Control (2 times a day 0.2% chlorhexidine) Systemic Tx (only if debridement to response is minimal) - Metronidazole (antibiotics - 200mg a week) - Penicillin (alternative) Primary Herpetic Gingivostomatitis - how does it look? how does it spread? - ANSWERVesicles Rupture---> Ulceration --> Spread Painful Continues...
