,DHYG 302 Introduction to DH –Final Exam Study Guide
Week 1 Learning Objectives
Wilkins Chapter 1
● Define the scope of dental hygiene practice. (S)
○ Brief History
Dr. Alfred C. Fones “father of DH”, trained his assistant to demonstrate the value of
educationCoined the name DH thought it would create an association w/ the prevention, rather
than treatment of oral disease. Primarily education, Irene Newman first RDH
○ Know Clinical Services and primary, secondary and tertiary prevention. Clinical services
Preventive- the methods employed by the clinician and or patient to promote and maintain oral
health.
Primary- Measures carried out before disease occurs to prevent disease or
injury. Ex: Sealants to prevent caries, community water fluoridation, nutrition
education
Secondary- treatment of early disease to prevent further progression of potentially
irreversible conditions that, if not arrested, can lead eventually to extensive rehabilitation
treatment or even loss of teeth.
Ex: Root surface debridement, remineralization therapy, sealants on non cavitated caries
Tertiary- methods to replace lost tissues and to rehabilitate the oral cavity to a level where
function is near normal as possible after secondary prevention has not been successful.
Ex: Replacement of missing tooth, denture, implant, restorations (crowns, bone/tissue grafts)
▪ Educational- Strategies developed for an individual or group to promote behavior change to
make healthy lifestyle choices
▪ Therapeutic- clinical treatments designed to arrest or control disease and maintain oral tissues
in health.
DENTAL PRACTICE ACT LAW: says what we (DH) can and cannot do
,○ Know types of supervision (general vs direct)
▪ Direct: the dentist needs to be present in the clinic, any medication that goes inside the system
Ex: anesthetic injections, gingival curettage, nitrous sedation
General: The dentist has authorized the procedure for a patient of record but need not be present
when the authorized procedure is carried out by a licensed hygienist.
Interprofessional Collaborative Patient Care
Values/Ethics for Interprofessional Practice: work with individuals of other professions to
maintain a climate of mutual respect and shared values
Roles/Responsibilities: use knowledge of one’s own role and those of other professions to
appropriately assess and address health needs of patient to promote and advance health of
populations (ex: nutrition consultant)
Interprofessional Communication: communicate with patients, families, communities, and
professionals in health and other fields in a responsive and responsible manner that supports a
team approach to the promotion and maintenance of health and prevention and treatment of
disease
Teams and Teamwork: apply relationship building values and the principles of team dynamics to
perform effectively in different team roles to plan, deliver, evaluate patient centered care
● Identify the components of the Dental Hygiene Process of Care. (K)
○ ADPIED AND Be able to describe what each stage means:
▪ Assessment
Collecting subjective and objective data
▪ Diagnosis
Interpret data using critical thinking skills
Identify health behaviors and actual or potential oral health problems within scope of practice for
DH
Justify proposed treatment to the patient
, ▪ Plan
Set of strategies and interventions needed to help patient attain oral health
Present to dentist for integration w/ comprehensive dental care plan
Present to patient: what treatment is needed, # of appointments it will take, obtain consent
▪ Implementation
Activation of the care plan, treatment
▪ Evaluation
Determines if:
A specific area needs to be retreated, patient needs referral, or if the patient can be placed into a
regular schedule of continuing care
▪ Documentation
All assessment data, diagnosis, care plan, treatments, patient education, evaluation
Examine legal, ethical, and personal factors affecting dental hygiene practice. (V)
Core Values in Professional Dental Hygiene Practice
Individual autonomy and respect for human beings: people have the right to be treated with
respect, they have the right to informed consent prior to treatment, full disclosure so they can make
informed choices about their care
Confidentiality: respect confidentiality of patient information, we acknowledge our obligation to
justify any violation of a confidence
Societal trust: value patient trust and understand that trust in our profession is based on our
actions and behavior
Nonmaleficence: protect patients, minimizing harm to them and others involved in their treatment
Beneficence: promote well-being of individuals and the public by engaging in health
promotion/disease prevention activities
Justice/fairness: value justice and support fair and distribution of healthcare resources- all people
should have access to high quality, affordable oral health care
Veracity: accept our obligation to tell the truth and expect that others will do the same, seek truth
and honesty in all relationships
