fre attache ging.
located coronal to attached gingiva and is sep. from tooth structure by ging sulcus
interdental papila
triangular portion of free ging. located in interprox. embrasure b/n teeth just apical to contact areas
ging. col
depression in interdental ging. connecting buccal and lijngual papilla immediately apical to contact areas of adjacent teeth.
ep. is nonker. and its presense is based on presense of interdental contact
dentoging junction
attachment of gingiva to tooth
ep and CT
DGJ
formed as oral ep. fuses with REE during tooth eruption.
as tooth reaches fully erupted position, cell of the junc. ep.
replace those of REE
DGJ
sulcular ep.
strat. sq. non ker. ep. w/o rete pegs that extends from ging. margin to junc. ep.
lines the ging sulcus
junctinal ep.
strat to sigle layer nonker ep. w/o rete pegs that adhere to tooth surface at base of sulcus
provides ep. attachment to tooth.
have higher turnover rates and larger intercell spaces than sulcus and ging. ep.
junct. ep
ext. basal lamina
Junctional ep
attaches to underlying CT as elsewhere in body
attaches to cementum via hemidesmosome
doesnt have type 4 coll.
internal basal lamina
dentoging. CT
type 1 colagen makes up bulk of CT
fibroblast, leukocyte, mast ccell, elastic fibrin, PG, glycoproteins
DG CT
ging. fiber group
support ging. and aid in attachment in alv bone and teeth
continuous with PDL
resist ging. displacment
found at ging level
ging fiber groups
DG fibers
fan lateral from cementum into adjacent CT
alveolar fibers
fan coraonally from alveolar crest into adjacet CT
dentoperiosteal fibers
extend from cementum over the alveolar crest, and turn apically to insert into periosteum of buccal side of alv. bone
circumferential fibers
surround tooth in ciruclar fashion
help prevent rotational forces
located in lamina propia of marginal ging.
