BONE
 PDL attachment is to : alv. Bone proper or called bundle bone
 The crest of INTERDENTAL BONE is said to be parallel to the marginal gingiva
 Or you could also say it id parallel to the line drawn from the CEJ of adjacent teeth.
 Now if the position of CEJ of the neighboring tooth is variable, then the bone will be angulated towards the line.***

PERIODONTAL LIGAMENT
 Cells
o Fibroblast
o Osteoblast
o Cementoblast
o Cell rest of malassez

Lateral periodontal cyst from rest of serres ,while apical periodontal cyst from rest of malassez.
 Fibres
o Collagen
o Elastic fibres
 Cementoblasts present in pdl
 Cell rest of malassez seen commonly at apex

FIBRES OF PDL
 COLLAGEN 1,3,7
 Most dental tissue type I collagen fibres
o Eg: pdl,alveolar bone, cementum, gingiva, dentin
o They are most abundant
 Anchoring fibres are type 7, seen in pdl
 Type 3 also seen in pdl

Ageing OF PDL
 Elastic fibres increase and cells decreases
 Function of pdl
 Formative, nutritive, anchorage, cushioning (type 7)
