[Proteoglycans-phospholipids interactions: roles in dentine mineralization].

Electron-histochemical visualization of proteoglycans was carried out in the predentine and dentine of rat incisors. Using various techniques proteoglycans were seen to be located between the collagen fibres in predentine, whereas they were observed at the surface of groups of collagen fibres in dentine. The same distribution was found when electron histochemical techniques aiming to visualize phospholipids were used. This co-distribution may play role in the mineralization processes.
