Cell Formation
These are the cells responsible for the formation of new bone.
Osteoblasts
This is the normal process by which primary teeth are lost as succedaneous teeth develop.
Exfoliation
Out of which type of tissue is the periodontal ligament made up of?
Connective tissue
By the third week of development the cells of the embryo begin to form what three primary embryonic layers?
ectoderm, mesoderm, and endoderm
At how many weeks in utero do the primary teeth begin to form?
5 weeks
These are the cells responsible for the resorption of bone such as when roots are resorbed during the loss of primary teeth.
Osteoclasts
These teeth erupt within the first 30 days of life with lack of root formation and are removed so the infant does not swallow them when shed.
Neonatal teeth
The bony projection that separates one socket from another is called...
Interdental septum
The name of the fertilized egg that is formed when the sperm and egg first unite.
Zygote
At this stage the teeth begin to develop as 10 round structures in each arch.
Bud stage
The cells that form enamel known as ameloblasts consist of primarily what mineral?
Hydroxyapatite
At what age range will a child have both primary and permanent teeth in their mouth, known as mixed dentition.
6-10 years
The periodontium is the supporting structure for our teeth composed of what four primary structures.
The alveolar bone, periodontal ligament, cementum, and the gingival unit.
The stomodeum is another name for what area of the embryo?
primitive mouth
This is the stage where the cells begin to differentiate and become more specialized.
Bell stage
Pulp contains connective tissue which contains a type of cell responsible for formation of intercellular substance of the pulp called...
Fibroblasts
This term describes the growth and changes in the shape of existing bone as a response to forces placed on the tooth within its socket.
Remodeling
This is the highest point of the alveolar ridge where the alveolar bone forms with cortical plate on the facial and lingual sides of the alveolar process.
Alveolar crest
This is the future of the mandibular arch which forms bones, muscles, and nerves of the face.
first branchial arch (Meckel's cartilage)
List the three general categories of congenital factors that result in developmental anomalies.
structural, functional, and environmental
This is the process by which the parents each join 23 chromosomes during conception.
Meiosis
The external line at the neck or cervix of a tooth where the enamel and cementum meet.
cementoenamel junction
What are the four groups that gingival fibers (located in connective tissue) are divided into
Dentogingival, Circular, Alveologingival, and Dentoperiosteal
What are the three stages in the formation of the palate beginning at five weeks?
formation of primary palate, formation of secondary palate, fusion of the palate
Which layer becomes dental papilla and forms the pulp and dentin of the tooth?
mesoderm
