Fibers connecting adjacent teeth across the alveolar bone.

Includes fibroblasts, neutrophils, lymphocytes, plasma cells, macrophages, mast cells.

Composed mainly of glycosaminoglycans like dermatan sulfate and chondroitin sulfate.

Categorized into thick & flat (85%) and thin & scalloped (15%) types.

The most apical point of the marginal gingival scallop.

Normally stippled (orange peel texture); varies by age and sex.

Includes supraperiosteal arterioles, PDL vessels, and alveolar septa arterioles.

Depends on vascular supply, keratinization, and pigmentation.

A unique structure that attaches the gingiva to the tooth surface, with a turnover rate of 1 to 6 days.

A complex connective tissue surrounding the tooth root, connecting it to the alveolar bone.

The principal cell type found in the junctional epithelium of the gingiva.

The space between the tooth and the surrounding gum, measuring 1-3 mm in depth.

Procedures to create new gingival tissue when there is a deficiency.

The terminal portion of principal periodontal ligament fibers that attach to cementum and bone.

Fluid derived from serum and cells in the gingival sulcus, increased in inflammation.

A non-keratinized epithelial area between teeth that is prone to disease.

Oral mucosa covering the gingiva and hard palate.

Part of oral mucosa covering the alveolar process and neck of teeth.

Free gingiva that forms a collar around the teeth.

Firm, resilient gingiva tightly bound to the alveolar bone.

Gingiva occupying the space between adjacent teeth.

The non-keratinized epithelium at the base of the gingival sulcus.

The primary barrier in the mouth, stratified squamous epithelium.

Cementum is 45-50% inorganic (mostly hydroxapatite) and 50-55% organic (mainly type 1 collagen).

Type of cementum without incorporated cells, covering root dentin from CEJ to apex, thinnest at CEJ.

Type of cementum containing cementocytes, primarily present at the apical third of the root.

Area where cementum overlaps enamel; it can be complete, partial, or absent.

Cementum is crucial for tooth anchorage, providing resistance to resorption during orthodontic movements.

Both types are layered, but acellular lacks cells while cellular contains cementocytes in lacunae.

A poorly defined zone near the cementodentinal junction containing remnants of Hertwig’s sheath.

Cementum is more resistant to resorption than bone, allowing safe tooth movement during orthodontics.

A dental procedure to remove calculus and bacteria from teeth, often exposing dentin.

Loss of cementum from scaling leads to dentin exposure and sensitivity.

Bone structure supporting tooth sockets, formed at tooth eruption.

The inner wall of the tooth socket seen radiographically.

The spongy inner bone of the alveolar process that supports nerves and vessels.

Areas where the root is uncovered by bone but protected by periosteum and gingiva.

Bone adjacent to the periodontal ligament, rich in Sharpey’s fibers.

The process of bone resorption and formation that occurs throughout life.

The process of depositing calcium in tissues, common in bone formation.

Includes transseptal, alveolar crest, horizontal, oblique, apical, and interradicular fibers.

Specialized, calcified tissue covering the roots of teeth.

Includes physical support, remodeling, nutritional supply, and sensory functions.

Long-chain carbohydrates that help retain water and support tissue structure in PDL.
