Variants of Normal

These flashcards cover key concepts, clinical presentations, and locations of various oral conditions categorized under 'Variants of Normal'.

What are Fordyce Granules?

Ectopic sebaceous glands that appear as white, creamy white, or yellow slightly raised papules, 1-2 mm in diameter.

Where are Fordyce Granules commonly located?

Buccal mucosa, labial mucosa, and the vermillion border of lips.

What is Torus Palatinus?

A bony protuberance located on the hard palate, which is the most common intraoral lesion.

What are the clinical characteristics of Torus Palatinus?

Hard growths with smooth rounded contours, often with a sessile base and lobulated surface.

What is Melanin Pigmentation in the oral mucosa?

Generalized and constant dark pigmentation common in dark-skinned individuals due to increased melanin.

Where is the most common location for Melanin Pigmentation?

Attached gingiva.

What is a Retrocuspid Papilla?

A firm round papule approximately 1-4 mm in diameter, located on the lingual surface of attached gingiva.

What are Lingual Varicosities?

Enlarged dilated veins commonly seen in the elderly due to loss of elasticity in the vascular wall.

Where do Lingual Varicosities typically occur?

On the ventral surface of the tongue.

What is the Linea Alba?

A white line extending from posterior to anterior along the occlusal plane, typically on buccal mucosa.

What is Leukoedema?

A condition characterized by generalized opalescence commonly observed in dark-skinned individuals.

Where is Leukoedema located?

On the buccal mucosa.

What is a Lingual Thyroid Nodule?

Undescended, trapped remnants of thyroid tissue, more common in females.

What are the clinical features of a Lingual Thyroid Nodule?

Raised asymptomatic mass approximately 2 cm in diameter with a sessile base.

What is a Fissured Tongue?

A condition with numerous linear fissures or grooves 2-5 mm deep on the dorsal surface of the tongue.

What condition is associated with hyposalivation?

Fissured Tongue.

What is Median Rhomboid Glossitis?

Aysmptomatic rhomboid or ovoid shaped red area on the midline of the dorsum of the tongue, anterior to circumvallate papilla.

What causes Median Rhomboid Glossitis?

Chronic candida albicans infection.

What defines Geographic Tongue?

A benign inflammatory condition with irregular bald patches and a 'map-like' appearance.

Where does Geographic Tongue occur?

On the dorsum of the tongue, with patches that may change location daily.

What is Black Hairy Tongue?

A condition resulting from chromogenic bacteria and extrinsic factors that lead to brown-to-black filiform papillae.

Where is Black Hairy Tongue located?

On the dorsum of the tongue.

What is White Hairy Tongue?

A condition resulting from increased keratin production or decreased normal desquamation, leading to elongated white filiform papillae.

Where does White Hairy Tongue occur?

On the dorsum of the tongue.

What is Leukoplakia?

A protective reaction against chronic irritants that appears as a white plaque or patch that cannot be rubbed off.

Where can Leukoplakia be found?

On the lateral and ventral tongue, floor of the mouth, buccal/labial mucosa, and vestibule.

What is a clinical presentation of Fordyce Granules?

White, creamy white, or yellow slightly raised papules.

Which age group is most affected by Lingual Varicosities?

Common in the elderly.

How are the appearances of Torus Mandibularis described?

Hard growths that can be unilateral or bilateral, typically with lobulated surfaces.

What underlying factor is thought to contribute to Melanin Pigmentation?

Increased amounts of melanin deposited in the mucosa.

What is the size of a Retrocuspid Papilla?

Approximately 1-4 mm in diameter.

Describe the clinical feature of a Fissured Tongue in terms of depth.

Numerous linear fissures or grooves that are 2-5 mm deep.

What symptom is often associated with Median Rhomboid Glossitis?

It is usually asymptomatic.

Which lesions are often mistaken for other diseases due to their appearance?

Leukoplakia.

What distinguishes Geographic Tongue from other conditions?

Its patches of bald areas without filiform papillae that change location.

How does Leukoedema present when the mucosa is stretched?

It becomes less prominent.

What are the clinical features of Lingual Thyroid Nodules?

Asymptomatic masses that are sessile and located on the tongue.

What do Fissured Tongues commonly appear as?

Numerous grooves or fissures on the dorsal surface.

Describe the appearance of the Linea Alba.

A white line extending along the occlusal plane on the buccal mucosa.

What is commonly seen in dark-skinned individuals in relation to oral conditions?

Leukoedema and Melanin Pigmentation.

How can geographic tongue appearance vary?

Location may change from day to day.

What is the primary treatment for conditions like Leukoplakia?

Addressing the underlying irritants causing the condition.

What most commonly causes White Hairy Tongue?

Increased keratin production or decreased desquamation.
