Dental Hygiene Process of Care:
Preventive, Therapeutic & Supportive DH Procedures:
- identify and describe the elements and functions of a healthy periodontium.
- identify and describe root planing objectives, rationale, indications, contraindications,technique and evaluation.
- identify the objectives and rationale of the periodontal examination.
- identify and describe the procedures to evaluate the periodontium medical history,dental history, patient's chief complaint, physical examination, signs of inflammation of the gingiva,mucogingival involvement, periodontal probing,furcation invasions,mobility patterns, migration of tissue and teeth, alterations in occlusion/tooth position, existing restorations,radiographic examination.
Health Education Strategies
- identify and describe periodontal case typing (classification of periodontal diseases)
- identify the items included in a comprehensive periodontal examination and complete a periodontal charting of these findings.
- identify and describe the following types of inflammatory gingival enlargement and the appropriate treatment for each: chronic gingivitis, chronic gingivitis with vitamin C deficiency, leukemia, puberty, pregnancy, hormonal changes, and mouth breathing, allergic gingivitis,and desquamative gingivitis.
- identify and describe the following types of noninflammatory enlargement for: phenytoin gingival enlargement, and familial hereditary gingival enlargement.
- identify and describe the following changes in the oral mucosa membranes in childhood diseases and the appropriate treatment for each: chicken pox, measles, scarlet fever, and diphtheria.
- identify and describe the characteristics, radiographic findings, histopathology an etiology, prognosis and appropriate treatment for gingival recession.
- identify and describe the periodontal pocket including classification, formation, clinical appearance, and histological characteristics.
- identify and describe the pathway of inflammation and the resulting types of bone loss and periodontal pockets.
- identify and describe aggressive periodontitis and the appropriate treatment for this condition.
- identify and describe the following acute periodontal conditions and appropriate treatment for each: necrotizing ulcerative gingivitis, acute primary herpeticgingivostomatitis, abscesses, and pericoronitis.
Ethical & Legal Principles:
- identify and explain the primary etiologic factor of periodontal disease: plaque.
- identify and explain the secondary etiological factors/amenable to correction/extrinsic of periodontal disease: calculus, materia alba, stain, food debris/impaction, diet, existing pathological conditions, abnormal morphology/ function, occlusal trauma, iatrogenic factors, oral hygiene, and habits.
- identify and explain the secondary etiological factors/non-amenable to correction/intrinsic of periodontal disease: nutritional, hormonal, hematologic diseases, metabolic diseases, disease, psychological disorders, drugs, host defense systems, heredity, and age.
- define the following terminology associated with occlusion: occlusion, functional contacts; parafunctional contacts; physiological, traumatic and therapeutic
- explain the following concepts associated with occlusion: magnitude/direction/duration and frequency, primary and secondary occlusal trauma, etiological factors of occlusal trauma, clinical, histological and radiographic features of occlusal trauma
- describe the role of occlusion in the pathogenesis of periodontal disease.
Foothill College Dental Hygiene Program Competencies
- assess the value of the dental hygienist in the preventive, assessment, and treatment of periodontal disease and the maintenance of periodontal health.
- assess the value of cultural diversity in periodontal disease
Our graduates will be competent in:
- In assessing the oral health needs of diverse populations and providing comprehensive dental hygiene care for persons of allages/stages of life.
- In health education strategies for the prevention of disease & the promotion of health for individual clients and the community.
- In infection & hazard control procedures to prevent the transmission of infectious diseases.
- In the ethical and legal principles underlying the practice of dental hygiene.
