   Osmotic pressure - Water tends to move towards dense1 concentrations of ions. Sugar solutions on the surface of exposed dentine cause water to be drawn2 out of the dentinal tubules causing which distorts the odontoblast causing pain.

    Osseous integration3 - a term used to describe the desired adhesion between an implant4 and the bone which holds it in place.

    Osteoblasts - cells which differentiate5 from pericytes and secrete6 both the matrix and mineral of bone.

    Osteocalcin - a calcium7 binding8 protein, synthesised by the osteoblast and secreted9 into the matrix at the time of bone mineralisation. Mice bread without the osteocalcin gene10 develop heavy bones suggesting that osteocalcin is a negative regulator of bone formation

    Osteoclast - a multi-nucleate cellcapable of removing both the organic and mineral component11 of bone. Osteoclasts activity is controlled by nearby osteoblasts.

    Osteoid - the extracellular matrix inwhich bone forms. It is high in collagen and other bone proteins but lacks any crystal formation.

    Osteonectin - a bone glycoprotein which has the property of binding to both collagen fibres and the hydroxyapatite crystals, and thus may be important in initiating12 bone mineralisation by acting13 as a template for nucleation. Osteonectin is also produced by endothelial cells and plateletes and is able to bindfibrinogen.

    Osteopontin - an adhesive14 glycoprotein related to sialoproteins, which is secreted by osteoclasts to assist in their adhesion to the bone surface. After bone resorption it may then act as a signal to stimulate15 osteoblast activity

    Osteoporosis - a reduction in bone mass which occurs commonly in post menopausal females, but also in older men. It is due to a reduction in the activity of the ovaries and a decreased secretion16 of oestrogen. Bone formation and bone healing are not affected17 but more bone is resorbed by osteoclasts than is replaced. Lack of exercise is also a factor in bone loss.

    Oxytalin fibres - are related to elastic18 fibres, though they have a smaller core of elastin. They are found in the periodontal ligament and in the epidermis19 of thin skin, but not in the oral mucosa.
