periodontal tissues 2 (gingivae) Flashcards
which fibre supports the gingivae?
gingival fibre groups in the lamina propria
where are the circular gingival fibres found?
within gingiva circular around tooth helping keep it in its socket
where are the alveolo-gingival fibres found?
originate in the alveolar bone of interdental septum and extend into the gingiva
where are the dento-gingival fibres found?
originate in dentine and extend out into the gingiva
where are the dento-periosteal fibres found?
originate in dentine and attach to opposing side of interdental septum (side closest to the adjacent tooth)
what is free and attached gingiva?
free gingiva is not attached to the bone but attached gingiva is
what is the junctional epithelium and where is it attached?
the barrier between oral environment and body tissues found in dept of the sulcus.
how is epithelium attached to the enamel?
internal and external basal lamina
hemidesmosomes provide attachment
What is biological width?
Thickness of the junctional epithelium and the connective tissue between the crest of alveolar bone and the crown of the tooth.
Usually 2.04mm
