To get started with Image Review, choose from the list below:
A low power micrograph of a section through the lower jaw of an embryo. The tongue is visible at the upper right and Meckel's cartilage (the round structure) at the lower right. Several spicules of bone, oral mucosa, and the dental lamina are visible near the center of the micrograph. This section passes through a tooth bud, which is a further extension of the dental lamina into the mesenchyme around this very early tooth germ.
Meckel’s cartilage is the cartilage of the first branchial arch, providing support during development of the mandible. It disappears later in development, essentially making no contribution to the mandible. Remnants of Meckel’s cartilage form the malleus of the middle ear, the sphenomalleolar ligament and the sphenomandibular ligament.
Cementum
The Cementum is the part of the periodontium that attaches the teeth to the alveolar bone by anchoring the periodontal ligament.
Dentin & Pulp
Dentin is a calcified tissue of the body, and along with enamel, cementum, and pulp is one of the four major components of teeth.
Structure of Enamel
Enamel is the hardest substance in the human body and contains the highest percentage of minerals.
Facial Growth & TMJ
Facial Growth issues can create undue stress over time to the Tempromandibular joint (TMJ) causing inflammation.
Oral Mucous Membrane
The oral mucous is the membrane lining the inside of the mouth.
Gingiva & Dentogingival Junction
Gingiva are part of the soft tissue lining of th mouth. The Dentogingival Juntion holds in place the junctional or attachment epithelium.
Enamel Formation
Amelogenesis is the formation of enamel on teeth and begins when the crown is forming during the bell stage of tooth development.
Development of Teeth
Referred to as odontogenesis is the complex process by which teeth frorm from embryonic cells, grow, and erupt into the mouth..
Salivary Glands
Are exocrine glands, glands with ducts, that produce saliva. The also secrete amylase, an enzyme that breaks down starch into maltose.
Eruption & The Alveolar Process
Tooth Eruption is a process in tooth development in which the teeth enter the mouth and become visible.
