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
