Dental Terminology Related to Tooth Origin and formation

• Dentition: The teeth in the dental arch   * ^^Deciduous^^     * A term used to describe the primary teeth     * The first set of teeth (or tooth)     * Having the property of falling off or shedding   * ^^Permanent^^     * The second set of human teeth (except molars)     * They are also called succedaneous

      - What is a succedaneous tooth? %%A permanent tooth that replaces a primary tooth%%

      - What teeth are succedaneous? %%Incisors (both central and lateral), canines, first and second premolars%%

      - What teeth are not succedaneous? %%First, second and third molars%%

      - Why are some teeth nonsuccedaneous? %%Because they do not have primary predecessors%%   * ^^Mixed^^     * Deciduous + Permanent = Heterodont     * when does it begin? %%with the appearance of the first permanent molars%%.     * when does it end? %%with the exfoliation of the deciduous teeth%%

• Odont (prefix)   * related to dentition   * ex: odontoblast
• -genesis (suffix)   * related to the process of creation and formation   * ex: osteogenesis
• Exfoliate: Physiologic loss of primary dentition (to fall out)
• Eruption: The process of penetration of the tooth to the surrounding tissues (breaking out)

the ^^deciduous teeth^^ exoliate and ^^permanent teeth^^ erupt into the space

• proliferation: The process of increase in mass and number but ^^with the same characters^^

• differentiation: The process of acquiring different functions ^^from the original source^^

• -blast (suffix)   * the function of tissue ^^creation^^ by a specialized cell type   * ex: fibroblast

• -cyte (suffix)   * the function of tissue ^^maintained^^ by a specialized cell type   * ex: fibrocyte

• -clast (suffix)   * the function of tissue ^^destruction^^ by a specialized cell type   * ex: fibroclast
