| Embryology | The study of prenatal development |
| Embryonic | Stage of human development that occurs from the beginning of the second week to the end of the eighth week |
| Enamel lamellae | Thin, leaflike structures that extend from the enamel surface toward the dentinoenamel junction and consist of organic material with little mineral content |
| Enamel organ | Part of a developing tooth destined to produce enamel |
| Enamel spindels | The ends of odontoblasts (dentin-forming cells) that extend across the dentinoenamel junction a short distance into the enamel |
| Enamel tufts | The hypocalcified or uncalcified ends of groups of enamel prisms that start at the dentinoenamel junction and may extend to the inner third of the enamel |
| Exfoliation | The normal process of shedding the primary teeth |
| Fetal period | Stage of human development that starts at the beginning of the ninth week and ends at birth |
| Fibroblasts | Type of cell in connective tissue responsible for the formation of the intercellular substance of pulp |
| Gestation | Stage of human development that starts at fertilization and ends at birth |
| Histology | The study of the structure and function of body tissues on a microscopic level |
| Hunter-Schreger bands | Alternating light and dark bands in the enamel that are produced when enamel prisms intertwine or change direction |
| Hydroxyapatite | Mineral compound that is the principal inorganic component of bone and teet |
| Hyoid arch | The second branchial arch, which forms the styloid process, stapes of the ear, stylohyoid ligament, and part of the hyoid bone |
| Lamina dura | Thin, compact bone that lines the alveolar socket; also known as the cribriform plate |
| Lining mucosa | Mucous membrane that covers the inside of the cheeks, vestibule, lips, soft palate, and underside of the tongue and acts as a cushion for underlying structures |
| Mandibular | The lower jaw |
| Meiosis | Reproductive cell production that ensures the correct number of chromosomes |
| Modeling | Bone changes that involve deposition and resorption of bone and occur along articulations as they increase in size and shape to keep up with the growth of surrounding tissues; also known as displacement |
| Odontoblasts | Cells that form dentin |
| OsteoBLASTS | Cells that FORM bone |
| Periodontium | Structures that surround, support, and are attached to the teeth |
| Preimplantation period | Stage of development that occurs during the first week after fertilization |
| Prenatal | Stage of human development that starts at pregnancy and ends at birth |
| Primary cementum | Cementum that covers the root of the tooth and is formed outward from the cementodentinal junction for the full length of the root |
| Primary dentin | Dentin that forms before eruption and that makes up the bulk of the tooth |
| Primar palate | The shelf that separates the oral and nasal cavities |
| Prism | A calcified column or rod |
| Pulp chamber | The space occupied by pulp |
| Remodeling | Growth and change in shape of existing bone that involves deposition and resorption of bone |
| Resorption | The body’s processes of eliminating existing bone or hard tissue structure |
| Secondary cementum | Cementum that is formed on the apical half of the root; also known as cellular cementum |
| Secondary dentin | Dentin that forms after eruption and continues at a very slow rate throughout the life of the tooth |
| Secondary plate | The final palate formed during embryonic development |
| Specialized mucosa | Mucous membrane on the tongue in the form of lingual papillae, which are structures associated with sensations of taste |
| Stomodeum | The primitive mouth |
| Stratified squamous | Layers of flat, formed epithelium |
| Striae of retzius | Incremental rings that represent variations in deposition of the enamel matrix during tooth formation |
| Succedaneous | Permanent teeth that replace primary teeth |
| Tertiary dentin | Dentin that forms in response to irritation and appears as a localized deposit on the wall of the pulp chamber; also known as reparative dentin |
| Tooth buds | Enlargements produced by the formation of dental lamina |
| Zygote | Fertilized egg |
| Masticatory | Oral mucosa that covers the hard palate, dorsum of the tongue, and gingiva |
| Odontogenesis | Formation of new teeth |
| OsteoCLASTS | Cells that RESORB bone |
| Radicular pulp | The other portion of pulp is known as root pulp. |
