periodontal ligament Flashcards
what makes up the periodontal ligament matrix
hyaluronate glycosaminoglycans
proteoglycans (sugars loaded with proteins)
glycoproteins (proteins loaded with sugars)
behaves like a viscous gel
what component of the periodontal ligament matrix suffers during periodontal disease
hyaluronate glycosaminoglycans
what sensory receptors are contained within PDLs
mechanoreceptors
nociceptors
true periodontal ligament
fibres connecting tooth to bone at/ apical to alveolar crest
gingival ligament
fibres mainly above alveolar crest
where is the alveolo-dental ligament found
connecting tooth to bone
run in various directions - horizontal (at alveolar crest), oblique , apical (at apex)
where are interdental ligaments (trans-septal fibres) found
located above alveolar crest
connect teeth together
function of PDLs
transmit biting forces to the alveolar bone
attach teeth to jaw
