Dentine tooth tissue. Coloured scanning electron micrograph (SEM) of dentine (substantia eburnea), which is a mineralised connective tissue found under a tooth's enamel. It forms the bulk of a tooth and differs from bone in its microscopic structure, which is seen here. Shown in cross-section are the dentinal tubules (dental canaliculi), which are where extensions from the odontoblast cells (part of the pulp at the core of a tooth) have formed the surrounding dentine matrix. These odontoblast extensions (or processes) allow dentine to rebuild itself, unlike enamel. Magnification: x460 when printed 10 centimetres wide.
