Study Notes
Objectives
- Recognize and describe oral tissues in both health and disease.
- Differentiate between healthy and diseased gingiva by identifying oral cavity features.
Buccal Mucosa
- Location of Stenson's duct, facilitating saliva flow into the mouth.
- Leukoedema presents as a filmy opalescence or diffuse whiteness, often with a folded appearance.
- Commonly associated with smoking and may show pigmentation changes.
The Hard Palate
- Characterized by palatine rugae and the incisive papilla located behind the maxillary incisors.
- Gentle palpation of the hard palate is necessary to check for lesions.
Tori (Torus Palatinus)
- Benign bony outgrowths in the maxilla/mouth, typically bilateral in the mandible.
- Present in approximately 20-35% of the population, varying in shape and size.
Dorsal Surface of the Tongue
- Healthy tongue exhibits a thin, white coating indicating proper digestive function.
- Taste buds are located on papillae, raised protrusions on the tongue's surface.
Ventral Surface of the Tongue
- Inspection includes the floor of the mouth, lingual frenum, and salivary ducts.
Lateral Surfaces of the Tongue
- Assessment involves visually checking dorsum, ventral, and lateral surfaces for ulcerations.
Examination of Lips
- Check for color, lesions, blisters, and palpate for abnormal lumps.
- Observe texture, color, and commissures for signs of dryness or cracking.
Linea Alba
- A white line along the occlusal plane, often bilateral, resulting from frictional activity of teeth.
Fordyce Granules
- Asymptomatic yellow grains (1-3 mm in size) derived from sebaceous glands, primarily on buccal mucosa and lips.
Clinical Features of Healthy Gingiva
- Healthy gingiva appears coral pink, with color variation based on vascularity; no bleeding occurs.
- Pigmented gingiva ranges from light brown to black based on skin complexion.
Tissue Contour Size and Shape
- Interdental papillae form a sharp point where teeth contact; diastema leads to flatter papillae.
- Healthy gingival margin meets tooth with a tapered knife-edge appearance.
Tissue Consistency and Texture in Health
- Firm attachment to tooth crowns; resilient tissue exhibits dimpled, stippled texture akin to orange peel.
Gingivitis
- Non-destructive inflammation of gums; reversible with good oral hygiene; may progress to periodontitis if untreated.
- Symptoms include reddened, swollen, tender gums that bleed easily.
Tissue Color in Gingivitis
- Gingiva appears bright red due to increased blood flow and tissue enlargement.
- Loss of stippling leads to shiny, swollen tissue with spontaneous bleeding.
Changes in Appearance of Papillae
- Enlarged gingiva exhibits increased size; bulbous papillae may occur from long-term inflammation.
- Blunted papillae do not adequately fill the interdental space; cratered papillae appear scooped out in necrotizing gingivitis.
Periodontitis
- Defined as inflammation of gums and supporting tooth structures, resulting in alveolar bone loss.
- Symptoms include bleeding on probing, spongy gingival margins, tooth mobility, and gingival recession.
