What is the correct sequence of the comprehensive periodontal diagnostic algorithm?

Identify → Confirm → Stage → Grade

Confirm → Identify → Grade → Stage

Identify → Stage → Confirm → Grade

Stage → Grade → Identify → Confirm

According to the blueprint, which clinical parameter is a better diagnostic measure for quantifying tissue loss?

Clinical attachment level (CAL)

Probing depth (PD) is measured from which reference point?

Cemento-enamel junction to pocket base

Alveolar crest to gingival margin

Clinical attachment level (CAL) uses which reference point?

Cemento-enamel junction / hard-tissue reference

Miller mobility Class 1 is described as:

Movement greater than 1 mm or vertical depression

First sign of movement, within normal range

Movement up to 1 mm in any direction

Miller mobility Class 2 is defined as:

Movement up to 1 mm in any direction

Which finding characterizes Miller mobility Class 3?

Movement up to 1 mm horizontally

Movement greater than 1 mm or vertical depression/rotation

Movement limited to physiological mobility

Glickman Grade I furcation involvement indicates:

A pocket into the flute with intact interradicular bone

A through-and-through lesion with visible recession

Loss of bone with the pocket not completely through

Glickman Grade II furcation involvement is characterized by:

Loss of bone, but the pocket does not pass completely through

Through-and-through lesion with clinically visible gingival recession

Glickman Grade IV differs from Grade III because Grade IV includes:

Clinically visible gingival recession in a through-and-through lesion

How is the plaque index recorded in the blueprint?

Percentage of bleeding sites only

Millimetres of plaque thickness

Which combination is used in the blueprint to identify clinical periodontal health?

BOP <10% and no attachment/bone loss from current disease; probing depth ≤4 mm with no BOP at 4 mm sites

Any furcation involvement with recession

The diagnostic criteria for gingivitis in the blueprint include:

Intact periodontium, BOP ≥10%, and no attachment loss due to previous periodontitis

CAL ≥5 mm and furcation involvement

PD ≥6 mm in at least two teeth

Which finding supports a diagnosis of periodontitis according to the diagnostic criteria page?

Interproximal CAL or radiographic bone loss, with specified pocket/furcation/defect findings

Plaque present on one surface only

Which feature is listed as a Stage III complexity factor?

Only horizontal bone loss with PD 3–4 mm

Probing depth ≥6 mm and vertical bone loss ≥3 mm

Need for full-mouth prosthetic rehabilitation in every case

Which statement best describes Stage IV periodontitis in the staging table?

CAL 1–2 mm and no complexity factors

CAL 3–4 mm with mostly horizontal bone loss

CAL ≥5 mm with need for complex rehabilitation due to functional or tooth-loss complications

Only localized gingival bleeding

How is the extent descriptor defined in the staging table?

Localized <10%; generalized ≥10%

Localized <30%, generalized, or molar-incisor pattern

Only by the number of missing teeth

Grade A periodontitis is associated with:

More than 2 mm bone loss over 5 years and bone loss/age >1.0

No bone loss over 5 years and bone loss/age <0.25

Less than 2 mm bone loss over 5 years and bone loss/age 0.25–1.0

Grade B progression is characterized by:

Less than 2 mm bone loss over 5 years and bone loss/age 0.25–1.0

More than 2 mm bone loss over 5 years and bone loss/age >1.0

Which combination is consistent with Grade C periodontitis?

No bone loss over 5 years and non-smoker

Bone loss/age <0.25 and HbA1c <7.0%

More than 2 mm bone loss over 5 years and bone loss/age >1.0

Less than 2 mm bone loss over 5 years and bone loss/age 0.25–1.0

Which patient modifier is shown under Grade C in the grading table?

Less than 10 cigarettes/day and HbA1c <7.0%

At least 10 cigarettes/day and/or HbA1c ≥7.0%

No smoking history regardless of glycemic control

The 'Good' prognosis category is described as:

Inadequate attachment for health, comfort and function

Adequate support and easy to maintain

More than 50% attachment loss with poor crown-root ratio

50% attachment loss and Grade II furcation

Which finding is associated with a 'Questionable' prognosis in the blueprint?

Adequate support and easy maintenance

Approximately 25% attachment loss and Grade I furcation

More than 50% attachment loss, poor crown-root ratio, Grade II/III furcation, or mobility 2/3

Which activity belongs to Step 1 of the stepwise periodontal treatment plan?

Regenerative periodontal surgery

Motivation and oral hygiene instructions (OHI)

Definitive restorative rehabilitation

Which treatment is included in Step 2 of the treatment plan?

Subgingival instrumentation (scaling/root planing)

Full-arch implant rehabilitation

Orthodontic correction before inflammation control

According to the treatment endpoints on page 10, successful therapy means:

No pockets >4 mm with BOP and no pockets ≥6 mm

All probing depths must be 1 mm

No plaque index recording is needed

When is Step 3 (surgical phase) indicated?

For every patient before Step 1

When areas do not respond to Step 2, with persistent pockets ≥4 mm with BOP or deep pockets ≥6 mm

Whenever a patient has plaque on one surface

Which of the following is listed as an intervention in Step 3?

Access flap periodontal surgery

Routine supragingival polishing only

Which finding is a distinctive feature of Stage IV periodontitis?

Loss of ≥5 teeth due to periodontitis and masticatory dysfunction

A Stage IV case with pathological tooth migration, elongation and flaring (Case 2) requires:

Correction without tooth replacement (splinting)

Prosthetic restoration without full-arch rehabilitation

Which sequence best represents Step 4 supportive periodontal care (SPC) and final review?

Surgery → extraction → diagnosis → no recall

Interview → assessment → evaluation → practical intervention → planning/recall

Radiograph → grading only → discharge

Plaque removal only at every visit
