Oral Histology and Embryology

Enamel is the outermost layer of the tooth and is composed of hydroxyapatite crystals.

The pulp provides nutrients and oxygen to the tooth, forms the dentin, and senses pain and temperature.

Sharpey's fibers, oxytalan fibers, and elastic fibers are all types of periodontal ligament fibers.

The amelodentinal junction is the junction between the enamel and the dentin in a tooth.

The parotid gland, submandibular gland, and sublingual gland are all types of salivary glands.

Saliva lubricates the oral cavity, helps to digest food, and protects the teeth from decay.

Masticatory mucosa, lining mucosa, and specialized mucosa are all types of oral mucosa.

The dental lamina is the embryonic structure that gives rise to the teeth.

Initiation, proliferation, and histodifferentiation are all stages in the development of a tooth.

Hertwig's epithelial root sheath is the structure that forms the root of a tooth.

Secretory odontoblasts, polarized odontoblasts, and mature odontoblasts are all types of odontoblasts.

Cementoblasts form the cementum, maintain the cementum, and sense pain and temperature.

Gingivitis and Periodontitis are types of periodontal disease.

Scaling and root planing, gingivectomy, and osseous surgery are all surgical procedures used to treat periodontal disease.

Squamous cell carcinoma, adenocarcinoma, and melanoma are all types of oral cancer.
