Periodontics MCQs

Periodontics is the study of what holds teeth in place and what happens when that attachment is lost: the gingiva, periodontal ligament, cementum, and alveolar bone in health, the biofilm and host response that drive disease, the diagnosis read from probing and the radiograph, nonsurgical and surgical therapy, and the decision about whether a periodontally compromised tooth can be kept. This section starts with a clinical map, then a core recall bank, then the clinical modules, and ends with the SDF connection.

Clinical Map

The periodontics clinical map.

Periodontics is the study of what holds teeth in place and what happens when that attachment is lost. The six areas below move from the healthy periodontium, to the biofilm and host response that drive disease, to the diagnosis that reads attachment levels, to nonsurgical and surgical therapy, and finally to the decision about whether a periodontally compromised tooth can be kept.

Every periodontal case is read as four tissues working together (gingiva, periodontal ligament, cementum, and alveolar bone) and a disease process that erodes them. The clinical questions stack: is this periodontium healthy or inflamed; if inflamed, is the disease gingivitis or periodontitis; how much attachment has been lost and where; what therapy is appropriate; and ultimately, can this tooth be kept? Because every restoration and every implant relies on the periodontium, the periodontal decision is read through the Structural Decision Framework (SDF): Structure, Force, Time, and Stability.

The Healthy Periodontium

Health is the baseline against which every other reading is taken. The periodontium is four tissues: the gingiva (free and attached), the periodontal ligament, the cementum, and the alveolar bone, joined at the junctional epithelium that seals the gingiva to the tooth.

The four tissues of the periodontium

Tissue	Role	Key feature
Gingiva	Soft-tissue seal around the tooth	Free, attached, mucogingival junction
Periodontal ligament	Suspension and proprioception	Sharpey's fibers, principal fiber groups
Cementum	Anchors PDL fibers to the root	Acellular cervical, cellular apical
Alveolar bone	Bony socket and Sharpey's anchor	Lamina dura on the radiograph
Junctional epithelium	Seal at the base of the sulcus	Hemidesmosomes to the tooth

Clinical pearl, Dental Door Rule

Healthy gingiva is coral pink, stippled, and knife-edge at the margin, the sulcus probes about 1 to 3 mm, and there is no bleeding on probing. The supracrestal attachment (formerly biologic width) is the junctional epithelium plus the connective tissue attachment above the alveolar crest, roughly 2 mm; restorative margins that violate it produce chronic inflammation, and crown lengthening reestablishes it.

The gingiva, periodontal ligament, cementum, alveolar bone, junctional epithelium, and the supracrestal attachment (biologic width) that is the baseline for everything else in periodontics.

The Disease: Biofilm and Host Response

Periodontal disease begins with a dental biofilm on the tooth and ends with bone resorbed by the host's own inflammatory response. The microbiology shifts to a dysbiotic, anaerobic, Gram-negative flora, and the host destroys its own attachment in trying to control the infection.

From biofilm to bone loss

Step	What happens	Note
Biofilm	Plaque colonizes the tooth at the gingival margin	Calculus is calcified biofilm
Dysbiosis	Shift toward anaerobic Gram-negative flora	Red complex: P. gingivalis, T. forsythia, T. denticola
Host response	Cytokines, MMPs, RANKL drive resorption	Most attachment loss is host-mediated
Gingivitis to periodontitis	Attachment loss begins	Reversible vs irreversible

Clinical pearl, Dental Door Rule

Periodontal disease is an infection with a host-mediated injury: biofilm and dysbiosis trigger an inflammatory response that ultimately resorbs the attachment apparatus. Gingivitis is reversible; once attachment is lost (periodontitis), the apparatus does not regrow without therapy. The strongest single modifiable factor is plaque control, and the strongest systemic risk factors are smoking and diabetes.

Deep dive

Periodontal Microbiology & Pathogenesis →

Plaque biofilm, dysbiosis and the red complex, the host immune-inflammatory response (cytokines, MMPs, RANKL) that resorbs attachment, and the gingivitis-to-periodontitis shift.

The Diagnosis: Probing, Attachment, and Bone

Periodontal diagnosis is read with the periodontal probe and the radiograph: probing depth and bleeding for inflammation, clinical attachment level (CAL) for the structural loss, and the radiograph for the bone level and pattern.

Reading the periodontium

Measurement	What it shows	Anchor
Probing depth (PD)	Sulcus or pocket depth	Gingival margin to base of sulcus
Clinical attachment level (CAL)	True structural loss	CEJ to base of sulcus
Bleeding on probing (BOP)	Inflammation	Healthy gingiva does not bleed
Radiographic bone level	Bone loss and pattern	Horizontal vs vertical defects

Clinical pearl, Dental Door Rule

Clinical attachment level (probing depth plus recession, measured from the cementoenamel junction) is the true measure of structural loss, while probing depth alone reflects only the position of the gingival margin. The 2017 classification stages periodontitis I to IV by severity (largely CAL and bone loss) and grades A to C by rate or risk, and gingivitis is set apart as reversible inflammation without attachment loss.

Probing depth, clinical attachment level, bleeding on probing, furcation and mobility, radiographic bone loss, and the 2017 staging and grading of periodontitis.

Nonsurgical Periodontal Therapy

First-line treatment is mechanical: scaling and root planing to disrupt and remove the biofilm and calculus, paired with patient oral hygiene to keep it from coming back, and reevaluation to decide what (if anything) needs more.

Nonsurgical therapy

Step	Purpose	Note
Scaling and root planing (SRP)	Mechanical biofilm and calculus removal	The foundation of therapy
Oral hygiene	Daily biofilm control by the patient	Without it, therapy fails
Antimicrobial adjuncts	Selective help when indicated	Local or systemic, case-by-case
Supportive therapy (maintenance)	Ongoing recall and re-instrumentation	Long-term recurrence control

Clinical pearl, Dental Door Rule

Scaling and root planing is the foundation of periodontal therapy, and daily plaque control by the patient is what makes any treatment last. Antimicrobial adjuncts are tools, not substitutes for debridement, and lifelong supportive periodontal therapy (maintenance) is the recurrence-control program that protects the result.

Deep dive

Nonsurgical Periodontal Therapy →

Scaling and root planing, oral hygiene and plaque control, local and systemic antimicrobial adjuncts, reevaluation, and supportive periodontal therapy (maintenance).

Surgical and Regenerative Therapy

When nonsurgical therapy leaves residual disease, or when defect morphology, esthetics, or restorative needs require it, surgery enters: access flaps, resective osseous surgery, regeneration, mucogingival grafts, and crown lengthening.

Periodontal surgical options

Procedure	Indication	Note
Open-flap debridement	Access to deep, residual pockets	Cleans where SRP cannot reach
Resective osseous surgery	Pocket reduction by reshaping bone	Sacrifices some support
Regenerative procedures	Vertical, contained defects	GTR, bone grafts, EMD
Mucogingival / soft-tissue grafts	Recession coverage, keratinized tissue	Esthetic and protective
Crown lengthening	Reestablish supracrestal attachment / restorative space	Reduces biologic-width violations

Clinical pearl, Dental Door Rule

Surgery is chosen for the situation: open-flap debridement gains access to deep pockets, resective surgery reduces pockets at the cost of some support, regeneration is reserved for contained vertical defects, mucogingival grafts cover recession and add keratinized tissue, and crown lengthening restores the restorative space the supracrestal attachment needs. The right operation depends on the defect, not the dentist's habit.

Open-flap debridement and resective osseous surgery, regeneration (GTR, bone grafts, EMD), crown lengthening, mucogingival/recession grafting, and furcation management.

The Periodontal Decision: Prognosis, Occlusion, and Peri-Implant

The final question is whether a periodontally compromised tooth can be kept, and how it interacts with occlusion, systemic disease, and any future implant. Periodontal prognosis, the maintain-versus-extract decision, and peri-implant disease are read through SDF.

The maintain-vs-extract decision

Factor	What to assess	Why it matters
Attachment and bone	CAL, bone level, furcation, mobility	Defines structural reserve
Force	Occlusal trauma, parafunction, mobility	Adds stress to a weakened periodontium
Disease activity	BOP, progression, response to therapy	Active disease worsens prognosis
Patient and risk	Plaque control, smoking, diabetes, adherence	Predicts long-term stability

Clinical pearl, Dental Door Rule

Periodontal prognosis weighs the structural reserve (attachment, bone, furcation, mobility) against the load and the risk: a tooth with little attachment and a furcation under heavy parafunction in a poorly controlled smoker is hopeless, while a tooth with reduced but stable attachment in a compliant patient may last for years. Peri-implant mucositis and peri-implantitis are the implant analogues, and the same SDF lenses (Structure, Force, Time, Stability) apply.

Pathologic Probing Depth
A probing depth of 4 mm or greater is generally considered:
- A.Diagnostic of trigeminal neuralgia
- B.Indicative of dental caries
- C.Normal for healthy gingiva
- D.Pathologic and suggestive of periodontitis
Answer: D.Pathologic and suggestive of periodontitis
Why
Healthy sulcular depths are typically 1 to 3 mm. Probing depths of 4 mm or greater, especially with bleeding on probing and attachment loss, suggest periodontitis. Probing depth alone does not establish the diagnosis; clinical attachment level, radiographic bone loss, and patient history are needed to stage the disease.

Junctional Epithelium Attachment
The junctional epithelium attaches to the tooth primarily by way of:
- A.Tight junctions only
- B.Periodontal ligament Sharpey fibers
- C.Hemidesmosomes
- D.Cementum collagen fibers
Answer: C.Hemidesmosomes
Why
The junctional epithelium attaches to the tooth surface through hemidesmosomes and an internal basal lamina. This attachment is biologically vital because it forms the gingival seal protecting the deeper periodontium from bacterial invasion. Sharpey fibers anchor the periodontal ligament to cementum and bone, not the junctional epithelium.

Class II Furcation
A Class II furcation involvement is defined as:
- A.Horizontal bone loss into the furcation that does not pass through to the opposite side
- B.Complete tooth mobility with vertical bone loss only
- C.Through-and-through bone loss across the furcation
- D.Furcation depression detectable but no bone loss
Answer: A.Horizontal bone loss into the furcation that does not pass through to the opposite side
Why
In the Glickman classification, Class I furcation involvement is incipient (detectable with a probe but without significant horizontal bone loss). Class II is partial horizontal bone loss into the furcation that does not pass entirely through. Class III is through-and-through bone loss covered by soft tissue. Class IV is through-and-through with the furcation clinically visible.

SDF Connection

Periodontal disease is the textbook SDF problem: a structure (attachment) under force (occlusion and biofilm) over time, and the question is whether stability holds.

Structure: Attachment, alveolar bone, periodontal biotype, furcation involvement, defect morphology.
Force: Occlusal trauma on a weakened periodontium, biofilm load, and the biomechanical stress from parafunction.
Time: Active disease vs maintenance, healing trajectory after therapy, and the recurrence risk that defines long-term success.
Stability: Will attachment levels hold: biofilm control, occlusal management, systemic risk factors, and patient adherence.
