Cat's tooth. Coloured scanning electron micrograph (SEM) of a vertical fracture through a canine tooth of a domestic cat (Felis catus). At the centre of the tooth (dark coloured oval) is the pulp cavity,containing specialized connective tissue and sensory nerve fibres (dental pulp). The bulk of the tooth is dentine (green),a mineralised tissue with a similar composition to bone. Within the dentine are channels (dental tubules),containing odontoblasts,cells which produce new dentine (not shown). Surrounding the dentine is enamel (brown),the hardest substance in the body. If damage occurs to the enamel,self-repair is limited | |
