gingival fibers

collagen type 1

type IV collagen (argyrophilic reticulum fiber)

elastic fiber system

types of connective tissue fibers

collagen type 1

forms the bulk of the lamina propria and provides the tensile strength to the gingival tissue.

type IV collagen (argyrophilic reticulum fiber)

branches between the collagen type I bundles and is continuous with fibers of the basement membrane and blood vessel walls.

elastic fiber system

is composed of oxytalan, elaunin, and elastin fibers distributed among collagen fiber

gingivodental

circular

transseptal

groups in gingival fibers

gingivodental group

Fibers those on the facial, lingual, and interproximal surfaces.

gingivodental group

They are embedded in the cementum just beneath the epithelium at the base of the gingival sulcus.

circular group

course through the connective tissue of the marginal and interdental gingiva and encircle the tooth in ringlike fashion

transseptal group

Located interproximally, form horizontal bundles that extend between the cementum of approximating teeth into which they are embedded.

transseptal group

They lie in the area between the epithelium at the base of the gingival sulcus and the crest of the interdental bone and are sometimes classified with the principal fibers of the periodontal ligament.

fibroblasts

The preponderant cellular element in the gingival connective tissue

fibroblasts

synthesize collagen and elastic fibers as well as the glycoproteins and glycosaminoglycans of the amorphous intercellular substance.

fibroblasts

also regulate collagen degradation

mast cells

neutrophils

what are the cellular elements of gingival connective tissue

mast cells

are distributed throughout the body, are numerous in the connective tissue of the oral mucosa and the gingiva.

neutrophils

can be seen in relatively high numbers in both the gingival connective tissue and the sulcus.

neutrophils

These inflammatory cells usually are present in small amounts in clinically normal gingiva

supplied by terminal branches of the posterior, middle, and anterosuperior alveolar nerves

what is the nerve supply of maxillary gingiva?

supplied by the buccal and mental nerves on the vestibular side and the sublingual nerve on the lingual

what is the nerve supply of mandibular gingiva?

lymphatic drainage of the gingiva

brings in the lymphatics of the connective tissue papillae.

lymphatic drainage of the gingiva

It progresses into the collecting network external to the periosteum of the alveolar process and then to the regional lymph nodes (particularly the submaxillary group).
