Periodontal Tissues Flashcards
What fibres are found between teeth?
transeptal
What fibres are found in between the roots of multirooted teeth?
inter-radicular
What fibres are found at the apex of the tooth?
apical
What fibres run from cementum into bone?
oblique
What are the 4gingival fibres?
dentoginigival
alveologinigval
circumferential
dentoperiosteal
What 2 types of bone make up the periodontium?
alveolar and basal
What typed of bone make up basal bone?
trabecular and cortical
What are features of trabecular bone?
spongy and cancellous
Where is the mucogingival junction?
between alveolar mucosa and attached gingiva
What gingiva is closest to the teeth?
free gingiva
What is the natural space between the tooth and gum called?
gingival sulcus
What type of epithelium makes the gingival sulcus?
sulcular epithelium
What is found at the base of the gingival sulcus?
junctional epithelium
What are the features of gingival epithelium?
keratinised
masticatory mucosa
How deep is the gingival sulcus?
0.5-3mm deep
What depth does gingival sulcus become in pathology?
more than 3mm
What does the gingival sulcus contain?
gingival crevicular fluid
Is the epithelium of the gingival sulcus keratinised or non-keratinised?
non-keratinised
What is the worst bit of epithelium in the mouth?
junctional epithelium
What makes junctional epithelium the worse part in the mouth?
- immature
- rapid turnover
- many intercellular spaces
- LEAKS
- gingival crevicular fluid passes through

65% mineral
23% organic matrix
12% water
What is the main function of cementum?
tooth support
What are 2 types of cementum?
acellular and cellular
