Midterm (week 1 & 2) Flashcards
primary DH intervention & example
Prevent the onset of disease or Injury through health protection and promotion
Ex) mouth guard, sealants, fluoride, education
Secondary DH intervention & example
Early Interventions aimed at stopping or minimizing progression of disease
Ex) desensitizing agents, routine cleaning
Tertiary DH intervention & example
Interventions to prevent disability and improve or restore function while preventing more deterioration
Ex) non surgical therapy
Fissure sealants
Cavity prevention, 80% effective on molars, quick, easy, painless
Mouth/head protection
Stabilizes jaw, covers teeth and palate, absorbs shock/energy during contact sports
Biomedical health model
Heavy reliance on medical care for improvements in health
Views health as a absence of disease
Behavioural health model
Views health as a product of lifestyle choices
Socio-environmental health model
Focuses on tackling the determinants of health , strategic approach
8 Determinants of health
Living and working conditions, social support, individual behaviour, genetic make-up, income, education, health services, gender
Gingival sulcus vs pocket
Sulcus indicated health, pocket indicates disease
Where is the JE (junctional epithelium) & healthy vs disease
Part of gingiva (gum) that attaches to directly to tooth (in pocket/sulcus)
Healthy - above CEJ
Disease - below CEJ
What is the CEJ (cemento-enamel junction)?
Area of union if the cementum and cervical region of tooth (crown and root)
Healthy gingival sulcus (mm)
0-3 mm, more than that indicates pocket/ unhealthy
Where is periodontal ligament ? Relate to healthy and disease
Attaches cementum (against tooth) to alveolar bone.
Intact in healthy and gingivitis
Destruction in periodontitis
Where is gingival fibre? Relate to health and disease
Found within gingiva (help hold gums against teeth)
Intact in health
Some destruction in gingivitis
Destruction in periodontitis
Basic states of periodontium
Health , gingivitis, periodontists
Appearance of healthy periodontium
Stippling, pink, scalloped, firm, no bleeding when probed, everything intact
Gingivitis
Reversible, only gingiva, JE attached below CEJ, some destruction of supra gingival fibres, ligaments intact, red or bluish coulor
Periodontitis
Non-reversible, infection of all parts of perudium, JE attached below CEJ, deconstruction of fibers and ligament and bone.
What is epidemiology?
Study of health and disease within the total population (risk factors that influence health)
Risk factors (6)
Gender, education level, socioeconomic status, age, behaviour, access to health care
Disease prevalence
Number of all cases of a disease which are identified in a specific population at a given point in time
Disease incidence
Number of new cases in a population that occur over a period of time
Variables associated with periodontal disease (measuring)
Tissue coulor changes and swelling, loss of bone and supportive structures, degree of bleeding, probing depths
