- - - - alveolar ridges becomes thickened broad and rounded
      - teeth spaced
      - increase vascularity
      - building of the central third
      - pain in active stages
  - - - osteoclastic resorption+fibrovascular proliferation
      - osteoblast lay down new bone
    - - increased osteoblastic activity and irregular cortical bones with presence of hematoxyphilic reversal line giving the characteristic mosaic pattern
      - marrow spaces were filled with fibre vascular connective tissue
- - - - mandible+other bones+viscera/skin

        10% patients may loosened teeth (teeth mobility)
        
        mostly affects adults
