Cats tooth, SEM
Cats 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

EDITORS COMMENTS
This print showcases the intricate beauty of a cat's tooth, captured through a coloured scanning electron microscope (SEM). The image reveals a vertical fracture that runs through the canine tooth of a domestic cat. At the heart of this dental marvel lies the pulp cavity, housing specialized connective tissue and sensory nerve fibers known as dental pulp. The bulk of the tooth is composed of dentine, which exhibits a striking green hue reminiscent of bone. Within this mineralized tissue are channels called dental tubules, containing odontoblasts – cells responsible for generating new dentine. Enveloping the dentine is enamel, boasting an alluring brown shade and recognized as one of nature's toughest substances. Delving into its biological significance, this photograph sheds light on the anatomy and structure underlying feline teeth. It serves as a testament to their remarkable adaptability in hunting and survival within their natural habitats. However, it also highlights that if damage occurs to the enamel layer, self-repair mechanisms are limited. Through this mesmerizing visual exploration at microscopic levels, we gain insight into both zoological wonders and dental biology alike. This extraordinary image from Science Photo Library invites us to appreciate nature's intricacies while deepening our understanding of these incredible creatures - Felis catus - who share our lives with such grace and mystery.
