Oral Pathology MCQs

Oral pathology on the INBDE is pattern recognition: leukoplakia vs lichen planus vs candidiasis, odontogenic cysts vs tumors, salivary gland disease, and the systemic conditions that present in the mouth. This section starts with a clinical map, then a core recall bank, then the clinical modules.

How to use this section

Six passes through oral pathology.

Step 1
Learn the map
Start with the Clinical Map below to see how mucosal lesions, oral cancer, odontogenic cysts and tumors, bone disease, salivary gland pathology, and systemic disease fit together.
Step 2
Drill Core Recall
Move to the Core Recall Bank to lock in the facts across cysts and tumors, bone and jaw lesions, infections, and the high-yield diagnoses.
Step 3
Study the modules
Work through the Clinical Modules: mucosal and soft tissue lesions, oral cancer and premalignancy, odontogenic cysts and tumors, bone and jaw pathology, salivary gland pathology, and systemic disease with oral manifestations.
Step 4
Practice Patient Cases
Work the INBDE patient cases in each module to reason from a clinical finding to a differential to a watch, biopsy, or refer decision.
Step 5
Build the differential
Focus on the lesions that look alike: white patches, ulcers, radiolucencies, and pigmented lesions. Differentials are how pathology is tested and how it is practiced.
Step 6
Connect to dentistry
Throughout, the job is recognition and triage: reassure the benign, remove the reactive, and biopsy or refer the dangerous, and never dismiss a non-healing lesion.

Clinical Map

The oral pathology clinical map.

Oral pathology is pattern recognition: sorting what you see in the mouth into the benign things to reassure, the reactive things to remove, and the dangerous things to biopsy or refer. The six areas below move from the soft tissue lesions, to oral cancer, to the cysts and tumors of the jaws, to bone disease, to the salivary glands, to the systemic diseases that announce themselves in the mouth.

For the boards and at the chair, oral pathology asks a few recurring questions: is this white patch a harmless callus or a precancer, is this ulcer a simple canker sore or an autoimmune disease, is this radiolucency around a tooth a cyst or a tumor, and is this oral finding a sign of disease elsewhere in the body. The skill is to recognize the pattern, decide whether to watch, treat, biopsy, or refer, and never to dismiss a non-healing lesion.

The Soft Tissue: Mucosal Lesions You See Every Day

Most of what appears on the oral mucosa is benign or reactive. Sorting lesions by color, by whether they wipe off or stretch away, and by how long an ulcer lasts is what separates the things to reassure from the things to biopsy.

Common mucosal and soft tissue lesions

Category	Examples	Key clue
White lesions	Frictional keratosis, leukoedema, lichen planus	Frictional resolves; leukoedema disappears on stretch
Reactive growths	Irritation fibroma, pyogenic granuloma, epulis fissuratum	Caused by chronic irritation; remove the cause
Immune ulcers	Aphthous ulcers, pemphigus, pemphigoid, erythema multiforme	Chronic or widespread ulcers need biopsy
Pigmented	Amalgam tattoo, melanotic macule, melanoma	Most are benign; a changing lesion needs biopsy
Tongue variants	Geographic tongue, fissured tongue, Fordyce granules	Benign variants of normal to recognize and reassure

Clinical pearl, Dental Door Rule

The first questions for a white lesion are whether it wipes off (think candidiasis) and whether it disappears when you stretch the mucosa (leukoedema). For an ulcer, the clock matters: a sore that does not heal in about two weeks is biopsied, not watched. Chronic multiple ulcers, sloughing gingiva, or a positive Nikolsky sign point to autoimmune disease that needs biopsy with immunofluorescence and referral.

The Threat: Oral Cancer and the Precancerous Lesions

The highest-stakes job in oral pathology is catching squamous cell carcinoma early and recognizing the premalignant lesions that precede it. This is where the oral exam saves lives.

Premalignant and malignant lesions

Lesion	What it is	Significance
Leukoplakia	A white patch that cannot be wiped or rubbed off	Premalignant; biopsy to assess dysplasia
Erythroplakia	A red velvety patch	Higher malignant potential than leukoplakia
Epithelial dysplasia	Disordered epithelium on biopsy	The histologic precursor of cancer
Squamous cell carcinoma	The most common oral malignancy	Tobacco, alcohol, and HPV are key risks

Clinical pearl, Dental Door Rule

A white patch that cannot be wiped off (leukoplakia), and especially a red patch (erythroplakia), is premalignant until biopsy proves otherwise. The classic high-risk sites are the floor of mouth, ventral and lateral tongue, and soft palate. Any non-healing ulcer, indurated lesion, or unexplained mass deserves biopsy or prompt referral; early oral cancer is far more survivable than late.

Deep dive

Oral Cancer & Premalignancy →

Leukoplakia and erythroplakia, epithelial dysplasia, squamous cell carcinoma and its high-risk sites, the tobacco, alcohol, HPV, sun, and betel-nut risk factors, and the recognize-and-biopsy decision.

The Jaws: Odontogenic Cysts and Tumors

Radiolucencies and radiopacities in the jaws are a category of their own, because the teeth and their developmental tissues produce cysts and tumors found nowhere else in the body.

Common odontogenic lesions

Lesion	Origin / location	Note
Radicular (periapical) cyst	At the apex of a non-vital tooth	The most common odontogenic cyst
Dentigerous cyst	Around the crown of an unerupted tooth	Classically the third molar
Odontogenic keratocyst	Often the posterior mandible	Aggressive, high recurrence; think of Gorlin syndrome
Ameloblastoma	Posterior mandible	Benign but locally aggressive; soap-bubble look
Odontoma	Tooth-forming tissues	The most common odontogenic tumor; a hamartoma

Clinical pearl, Dental Door Rule

A radiolucency at the apex of a non-vital tooth is usually a periapical (radicular) cyst or granuloma, while one around the crown of an impacted tooth suggests a dentigerous cyst. Pulp testing and the relationship to the tooth guide the diagnosis. Aggressive or recurrent lesions (odontogenic keratocyst, ameloblastoma) need referral, and multiple keratocysts should prompt thinking about Gorlin (nevoid basal cell carcinoma) syndrome.

Deep dive

Odontogenic Cysts & Tumors →

Radicular, dentigerous, and odontogenic keratocysts, ameloblastoma, odontoma, and the other tumors of the tooth-forming tissues, read through pulp vitality and the relationship to the tooth.

The Bone: Fibro-Osseous Disease and the Necrotic Jaw

Beyond the teeth, the jawbones develop fibro-osseous lesions, giant cell lesions, and the drug- and radiation-related necrosis that dentistry must actively prevent.

Bone and jaw conditions

Condition	Feature	Dental relevance
Fibrous dysplasia	Ground-glass bone, painless swelling	Often young patients; a fibro-osseous lesion
Periapical cemento-osseous dysplasia	Lesions at apices of vital anterior teeth	Common, benign; do not mistake for pathology needing endo
Central giant cell granuloma	Anterior mandible radiolucency	Distinguish from a true tumor
Osteomyelitis	Infection of bone	Pain, swelling, sometimes after extraction
MRONJ / osteoradionecrosis	Exposed necrotic bone	Linked to antiresorptives and prior radiation

Clinical pearl, Dental Door Rule

Before starting antiresorptive therapy (bisphosphonates, denosumab) or head and neck radiation, the patient should be made dentally fit, because extractions afterward carry the risk of medication-related osteonecrosis of the jaw (MRONJ) or osteoradionecrosis. Prevention (completing needed extractions first, then conservative care) is far easier than treating exposed necrotic bone.

Bone & Jaw Pathology →

Fibro-osseous lesions, giant cell lesions, Paget disease, osteomyelitis, osteoradionecrosis, and medication-related osteonecrosis of the jaw, plus the benign and malignant bone tumors.

The Glands: Salivary Gland Pathology

The salivary glands produce their own spectrum of disease, from the trivial blocked duct to benign and malignant tumors, plus the dry mouth of autoimmune disease.

Salivary gland conditions

Condition	What it is	Note
Mucocele / ranula	Mucus spillage (lip; floor of mouth)	Common; from a damaged minor duct or the sublingual gland
Sialolithiasis	Salivary stone	Mealtime swelling, often the submandibular duct
Sjogren syndrome	Autoimmune gland destruction	Dry mouth and dry eyes; raises caries and lymphoma risk
Pleomorphic adenoma	Most common salivary tumor	Benign, usually the parotid
Mucoepidermoid carcinoma	Most common salivary malignancy	A palatal swelling can be a minor-gland tumor

Clinical pearl, Dental Door Rule

Mealtime swelling of a gland points to an obstructing stone (sialolithiasis), and dry mouth with dry eyes raises Sjogren syndrome, which sharply increases caries risk and warrants aggressive prevention. A firm swelling on the palate is not always an abscess: a minor salivary gland tumor (benign or malignant) can present this way, so a non-fluctuant, non-odontogenic mass needs imaging and biopsy, not just incision.

Deep dive

Salivary Gland Pathology →

Mucocele and ranula, sialolithiasis and sialadenitis, Sjogren syndrome and xerostomia, and the benign and malignant salivary gland tumors.

The Body: Systemic Disease in the Mouth

The mouth is a window on the rest of the body. Blood, hormone, gut, and immune disorders all leave oral signs that a dentist may be the first to notice.

Oral signs of systemic disease

System	Oral sign	Underlying disease
Hematologic	Spontaneous gingival bleeding, gingival enlargement	Leukemia, bleeding disorders
Nutritional	Smooth sore (beefy) tongue, angular cheilitis	B12, folate, or iron deficiency
Endocrine	Diffuse mucosal pigmentation	Addison disease (adrenal insufficiency)
Gastrointestinal	Cobblestone mucosa, aphthous-like ulcers	Crohn disease
Immune / dermatologic	Oral lichenoid or erosive lesions	Lichen planus, lupus, pemphigus

Clinical pearl, Dental Door Rule

Read the mouth as a systemic chart. Spontaneous gingival bleeding or rapid gingival enlargement can be a presentation of leukemia; a smooth, sore tongue suggests a B12, folate, or iron deficiency; and diffuse new mucosal pigmentation can signal Addison disease. When an oral finding does not fit a local cause, think systemically and refer for the blood work or medical evaluation rather than treating the mouth in isolation.

Leukoplakia High-Risk Sites
Leukoplakia carries the highest risk of malignant transformation when located on the:
- A.Hard palate
- B.Floor of the mouth or ventrolateral tongue
- C.Buccal mucosa
- D.Attached gingiva
Answer: B.Floor of the mouth or ventrolateral tongue
Why
Leukoplakia on the floor of the mouth and ventrolateral tongue has the highest rate of malignant transformation to squamous cell carcinoma. Lesions on the hard palate, attached gingiva, and buccal mucosa generally carry lower risk. Biopsy is indicated when high-risk locations or worrisome features (induration, ulceration, adjacent erythroplakia) are present.
111
Dentigerous Cyst Origin
A dentigerous cyst is most commonly associated with the:
- A.Crown of an unerupted third molar
- B.Root furcation of a primary molar
- C.Maxillary central incisor only
- D.Apex of an erupted incisor
Answer: A.Crown of an unerupted third molar
Why
Dentigerous cysts form around the crown of an unerupted or impacted tooth, most commonly the mandibular third molar. They attach at the cementoenamel junction and appear as well-defined unilocular radiolucencies surrounding the crown. Radicular cysts, in contrast, are associated with the apex of a non-vital tooth.
131
Pleomorphic Adenoma Site
Pleomorphic adenoma is most commonly found in the:
- A.Minor salivary glands of the soft palate only
- B.Submandibular gland only
- C.Parotid gland
- D.Sublingual gland
Answer: C.Parotid gland
Why
Pleomorphic adenoma is the most common benign salivary gland tumor and occurs most frequently in the parotid gland. It presents as a slow-growing, painless, mobile mass. It can also arise in the submandibular gland or minor salivary glands (especially of the palate). Malignant transformation is uncommon but possible if left untreated.
