SECTION 1: DENTAL HYGIENE PROCESS OF CARE Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A 34-year-old patient presents for their initial dental hygiene appointment with complaints of
bleeding gums when brushing. Their medical history reveals well-controlled type 2 diabetes
(HbA1c 6.8%) and they take metformin 500mg twice daily. Intraoral examination reveals
generalized 4-5mm probing depths, heavy interdental plaque, and BOP score of 65%. The
dental hygienist has completed the assessment phase and is now formulating a diagnosis.
According to the Dental Hygiene Process of Care, which phase directly follows the Diagnosis
phase?
A. Assessment
B. Planning ✓ CORRECT
C. Implementation
D. Evaluation
Correct Answer: B
Rationale: The Dental Hygiene Process of Care consists of six sequential phases: Assess,
Diagnose, Plan, Implement, Evaluate, and Document; the Planning phase immediately follows
Diagnosis and involves establishing prioritized goals and evidence-based interventions.
Choice A (Assessment) is incorrect because it is the first phase and precedes Diagnosis, not
follows it; confusing the order of the first two phases is a common exam trap. In clinical
practice, always document the diagnosis using standardized terminology such as the GDC
Scope of Practice before proceeding to treatment planning.
Question 2 of 50
A 28-year-old patient with a history of generalized anxiety disorder (managed with sertraline
50mg daily) attends for periodontal maintenance. During the re-evaluation appointment 8
,weeks after initial non-surgical periodontal therapy, the hygienist records a reduction in mean
probing depth from 5.2mm to 3.8mm and a decrease in BOP from 72% to 35%. The patient
reports improved oral hygiene compliance. Which phase of the Dental Hygiene Process of
Care is the hygienist primarily engaged in during this appointment?
A. Assessment
B. Planning
C. Implementation
D. Evaluation ✓ CORRECT
Correct Answer: D
Rationale: The Evaluation phase involves measuring outcomes against the goals established
during the Planning phase, including reassessment of clinical parameters such as probing
depths, BOP, and patient-reported outcomes. Choice C (Implementation) is incorrect because
the active therapy was completed during prior appointments; this visit is specifically
measuring the success of that implemented care, which is the defining feature of Evaluation.
When documenting evaluation findings, always compare current data to baseline
measurements to demonstrate measurable improvement or identify areas requiring further
intervention.
Question 3 of 50
A 52-year-old male patient with a history of hypertension (amlodipine 5mg daily) and former
smoking (quit 3 years ago, 20 pack-year history) presents for a new patient examination. The
hygienist performs a comprehensive health history, extraoral and intraoral examination,
periodontal charting, radiographic review, and risk assessment. The patient has localized
6-7mm probing depths in the posterior sextants with grade II furcation involvement on #14
and #19. According to the Dental Hygiene Process of Care, at which point should the
hygienist document the clinical findings?
A. Only after the final treatment has been completed
B. Continuously throughout all phases ✓ CORRECT
C. Exclusively during the Assessment phase
D. Only when submitting insurance claims
Correct Answer: B
Rationale: Documentation is an ongoing responsibility throughout all six phases of the Dental
Hygiene Process of Care, not a single discrete step; accurate contemporaneous recording
ensures legal protection, continuity of care, and compliance with GDC Standards. Choice C is
incorrect because limiting documentation to the Assessment phase would omit critical
treatment records, informed consent, and outcome evaluations; this is a frequent exam trap
because Documentation is sometimes mistakenly viewed as part of Assessment rather than
a parallel obligation. Develop the habit of documenting immediately after each clinical
interaction to prevent recall errors and ensure medico-legal defensibility.
, Question 4 of 50
A 41-year-old patient with rheumatoid arthritis (methotrexate 15mg weekly) attends for
periodontal reassessment 12 weeks after initial therapy. The hygienist notes that while
buccal probing depths have improved from 5-6mm to 3-4mm, the lingual surfaces of the lower
anterior teeth remain at 5-6mm with persistent BOP. The patient admits to difficulty using
interdental brushes due to reduced manual dexterity. Which phase of the care process should
the hygienist revisit to address this unresolved problem?
A. Assessment
B. Diagnosis
C. Planning ✓ CORRECT
D. Implementation
Correct Answer: C
Rationale: When clinical outcomes do not meet established goals, the hygienist must return
to the Planning phase to revise the care plan, incorporating modified interventions such as
alternative oral hygiene aids (e.g., floss holders, water flossers) tailored to the patient's
physical limitations. Choice D (Implementation) is incorrect because simply repeating the
same interventions without strategic modification is ineffective; the error lies in failing to
recognize that suboptimal outcomes require plan revision, not just repeated implementation.
Always involve the patient in care plan modifications to ensure buy-in and realistic
goal-setting, particularly when physical or cognitive barriers exist.
Question 5 of 50
A 19-year-old university student presents for their first dental hygiene appointment in four
years. They report occasional gum bleeding and sensitivity to cold. The hygienist conducts a
full periodontal assessment, takes bitewing radiographs, performs a dietary analysis, and
completes a plaque index. The patient has generalized gingivitis with localized mild
periodontitis (site #30, 5mm probing, slight radiographic bone loss). Which phase of the
Dental Hygiene Process of Care includes the identification of "Localized Mild Periodontitis"
as the patient's condition?
A. Assessment
B. Diagnosis ✓ CORRECT
C. Planning
D. Implementation
Correct Answer: B
Rationale: The Diagnosis phase involves the clinical interpretation of assessment data to
identify the patient's oral health condition using recognized classification systems such as
the 2017 World Workshop on Periodontal Diseases; "Localized Mild Periodontitis" is a
diagnostic statement, not a data collection activity. Choice A (Assessment) is incorrect
