Periodontal Tissues

?
what makes up the periodontium
alveolar bone, periodontal ligament, cementum, gingiva
1 of 12
Where can the periodontal ligament be found and what does it contain
between tooth and alveolar bone. contains: cells- fibroblasts. fibres like collagen. ground substance. water. nerves. blood vessels
2 of 12
what are. the PDL functions
attachment: tooth to bone. Support: suspensory system, shock absorber. sensory - heavily innervated
3 of 12
What bones make up the alveolar bone
cortical - outer and trabecular - inner spongy and cancellous
4 of 12
what are the functions of oral mucosa
protection- mechanical, bacterial, chemical , prevent dehydration. sensation and secretion + thermal regulation
5 of 12
what tissues compromise the oral mucosa and give the 3 types of mucosa
epithelium and CT- lamina propria. 3 types of mucosa: masticatory, lining, specialised- gustatory mucosa
6 of 12
what are the oral mucosae of the periodontoum
gingival and alveolar
7 of 12
Give the differences between gingival and alveolar mucosa- the type of mucosa, epithelium, colour etc
mucosa: masticatory (G), Lining (A). Epithelium: thick G, thin A. Keratinised G, Non keratinised A. colour: pink G, Red A. Firm G, loose/ mobile A. Stippled G and. Smooth A
8 of 12
what are the.features of sulcular. epithelium . what type of epithelium is it
stratified squamous, non keratinised, shallow/. no rete pegs.. cells tightly packed
9 of 12
what are the 2 types of cementum. give the features of each
acellular: no cells, slow deposition, close incremental lines, narrow precementum. Cellular cementum: cells in lacunae with canaliculi, rapid deposition, incremental lines relatively apart. relatively wide precementum
10 of 12
what are the 4 fibres types
intrinsic , extrinsic , mixed and fibrillar
11 of 12
how would you describe the intrinsic and extrinsic fibres in relation to root surfaces
intrinsic: parallel extrinsic: perpendicular/ oblique to root surfaces
