gingivitis

Gingival site and case status

Record affected natural-tooth sites, working diagnosis and the definition used to assign a whole-mouth case.

1. Which tooth sites and gingival regions are affected, and are any observations actually around implants or elsewhere in the oral mucosa? boundary
2. Does the evidence establish individual inflamed sites, a whole-mouth gingivitis case or only suspected inflammation under the selected definition? definition
3. Who made the assessment, when, and from which examination or report? provenance

Support loss and history

Retain probing, attachment and relevant existing imaging evidence, including the attributed cause of any reduced support.

1. What do site-level probing depths, gingival margin positions and attachment measurements show? measurement
2. Is periodontal support intact or reduced, and what evidence identifies the cause and any history of periodontitis? provenance
3. Do current findings require assessment through the periodontitis model before a gingivitis-only interpretation is acceptable? boundary

Interpretable bleeding extent

Record bleeding sites, examined sites, exclusions and technique before deriving an extent category.

1. How many sites bled, how many were examined and which teeth or sites were excluded? measurement
2. What probe, probing technique and bleeding observation interval were used, and was the examination full-mouth or partial? provenance
3. Does examination coverage justify a whole-mouth extent classification, or must it remain indeterminate? boundary

Local inflammatory expression

Record visible changes, spontaneous versus provoked bleeding and the effect on everyday oral function.

1. Which sites show swelling, altered contour or colour change relative to the person's usual gingival appearance? measurement
2. Is bleeding spontaneous or provoked, and what soreness or difficulty eating and cleaning does the person report? measurement
3. If an intensity score is assigned, which named scale supports it and how is it kept separate from extent? definition

Plaque-inflammation concordance

Compare plaque distribution with affected gingiva and record suspected retention or access problems.

1. Where are plaque and calculus present relative to the inflamed sites, using which observation method or index? measurement
2. Which restorations, appliances, tooth positions or cleaning difficulties are suspected local contributors? provenance
3. What evidence supports plaque association, and what findings remain unexplained by it? boundary

Modifier relevance

Record the timing and evidential basis of suspected modifiers of inflammation, bleeding or gingival enlargement.

1. Which medications, tobacco exposures, hormonal circumstances or known health conditions were present when inflammation began or changed? provenance
2. Could a documented modifier affect bleeding interpretation or tissue appearance, and what evidence supports that assessment? boundary
3. Which suspected contribution requires review by the treating dentist or relevant medical clinician? action

Unexplained gingival lesions

Describe atypical lesions without converting their appearance into an unsupported etiologic diagnosis.

1. Are there ulcers, necrotic papillae, desquamation, vesicles, focal masses or lesions extending beyond gingiva? measurement
2. Which competing explanations has a clinician considered, and what evidence supports or weakens each? boundary
3. What specialist examination or targeted investigation is needed to resolve the differential? action

Escalation basis

Record concerning symptoms, their evolution and the clinician or protocol responsible for urgency decisions.

1. Is there rapidly worsening pain or swelling, uncontrolled bleeding, fever, impaired swallowing or inability to maintain oral intake? measurement
2. Which applicable triage protocol or clinician assessment determines the urgency and destination of care? provenance
3. What referral or immediate-care action is indicated, and has it been arranged or completed? action

Agreed actions and feasibility

Link home plaque control, professional care and contributor review to specific findings and patient constraints.

1. What home-cleaning approach and professional care have been agreed for the affected sites? action
2. Which dexterity, discomfort, appliance, support or access barriers could prevent the plan from being followed? boundary
3. Who authorized any adjunctive product or procedure, for what indication and with what review point? provenance

Resolution, persistence or recurrence

Compare site findings, symptoms and contributor control before assigning an updated gingival state.

1. How have bleeding, swelling, symptoms and plaque changed at comparable sites since the baseline examination? measurement
2. What recorded criterion supports improvement, resolution, persistence or recurrence, and are the examinations comparable? definition
3. If inflammation persists or new attachment concerns appear, should the care plan change or the differential and periodontal assessment be reopened? action

Typical measurements

Reported by the breadth pass; each item needs checking against its source before it becomes normative.

• Bleeding on probing (BOP) - sites positive - Gingivitis case: BOP ≥10% of sites (localized 10-30%; generalized >30%); periodontal health <10% - % of probed sites
• Probing depth - Typically ≤3-4 mm without apical migration of the junctional epithelium; deeper pockets suggest periodontitis or pseudopockets from swelling - mm
• Clinical attachment loss (CAL) - 0 mm relative to the cemento-enamel junction on an intact periodontium (by definition no attachment loss attributable to periodontitis) - mm
• Gingival index (Löe-Silness) site score - 0 (normal) to 3 (severe inflammation, ulceration, spontaneous bleeding); gingivitis usually 1-2 - ordinal score 0-3
• Plaque index / visible plaque - Site-level presence; higher plaque scores correlate with BOP but are not the disease itself - ordinal score or % sites
• Gingival crevicular fluid volume - Elevated versus health; research use more than chairside - µL

Failure modes and hazards

Reported by the breadth pass; each item needs checking against its source before it becomes normative.

• Progression to periodontitis with irreversible attachment and bone loss if plaque biofilm and inflammation persist
• Under-diagnosis when BOP is not systematically recorded, especially in smokers (who bleed less despite inflammation)
• Overtreatment: scaling and surgery aimed at periodontitis when only gingivitis (no attachment loss) is present
• Necrotizing gingivitis: rapid papillary necrosis, pain, fetor; may extend to necrotizing periodontitis, especially with HIV, malnutrition, or smoking
• Drug-influenced enlargement impairing hygiene and trapping plaque, creating a self-reinforcing cycle
• Systemic contribution: gingival inflammation is associated with (not proven to cause) poorer glycaemic control and adverse pregnancy outcomes in observational literature
• Misattribution of bleeding to gingivitis when the cause is blood dyscrasia, vitamin C deficiency, or desquamative autoimmune disease

Regional variation

Reported by the breadth pass; each item needs checking against its source before it becomes normative.

• High-income settings: gingivitis is usually charted with BOP percentages and managed in general dental practice; periodontitis screening is protocolised
• Low- and middle-income settings: untreated plaque-induced gingivitis is highly prevalent; WHO reports periodontal disease among the most common NCDs, with limited specialist periodontology
• Necrotizing gingivitis historically clustered in malnourished children in parts of Africa (noma/cancrum oris pathway) and in stressed young adults in wartime or institutional settings
• Tobacco: smoking is globally common as a modifier; some regions have high smokeless-tobacco use that also inflames gingiva
• Pregnancy gingivitis counselling and timing of dental care differ by obstetric and dental-system norms
• Classification language: older 'acute/chronic' ICD-10 labels remain in billing in some countries; clinics using the 2017 AAP/EFP scheme speak of plaque-induced vs non-plaque-induced and localized vs generalized by BOP%

Neighbouring kinds and how to tell them apart

Reported by the breadth pass; each item needs checking against its source before it becomes normative.

• Periodontitis - Periodontitis shows clinical attachment loss and alveolar bone loss; gingivitis does not. A reduced but stable periodontium with BOP can still be gingivitis, not periodontitis, if there is no current additional attachment loss.
• Periodontal health - Health: BOP <10% of sites, no erythema/edema of inflammation, no attachment loss from periodontitis. Gingivitis: BOP ≥10% with inflammatory signs, still without periodontitis-related attachment loss.
• Gingival enlargement (fibrous hyperplasia) without primary gingivitis - Drug-, hormone-, or genetically driven overgrowth can exist with or without secondary plaque-induced inflammation; biopsy and drug history separate idiopathic/fibrous enlargement from purely inflammatory gingivitis.
• Desquamative gingival lesions (oral lichen planus, mucous-membrane pemphigoid, pemphigus vulgaris) - Painful epithelial sloughing, often with extra-gingival mucosal lesions; diagnosis by biopsy and immunofluorescence, not by plaque score alone.
• Necrotizing periodontitis / noma (cancrum oris) - Necrotizing gingivitis is limited to gingiva (papilla necrosis, pain, fetor); necrotizing periodontitis adds attachment and bone loss; noma extends through mucosa and facial tissues.
• Periodontal abscess or endo-periodontal lesion - Localized swelling, suppuration, and often a deep isolated pocket or non-vital tooth; gingivitis is a marginal, usually generalized inflammatory state without an acute abscess.
• Herpetic gingivostomatitis - Acute viral (HSV) disease with vesicles/ulcers on gingiva and often non-keratinized mucosa, fever and lymphadenopathy, especially in children; plaque-induced gingivitis lacks vesicles and systemic viral prodrome.
• Haematological gingival bleeding (leukaemia, thrombocytopenia, vitamin C deficiency/scurvy) - Bleeding out of proportion to plaque, possible petechiae or pallor; blood count, smear, and nutritional history separate these from ordinary plaque-induced gingivitis.
