Prerequisite: BIO 164
Competencies

Examine the stages of tooth development both morphologically and physiologically
1. Know the components of the tooth germ and it will produce
2. Differentiate the mineralization processes of enamel, dentin and cementum.
Assess Histological Development
1. Contrast the histological development and composition of enamel with that of dentin and cementum
2. Compare the histological development and composition of dentin with enamel and cementum
3. Contrast the histological development and composition of cementum with that of enamel and dentin.
Evaluate the periodontal ligament
1. Differentiate between the cellular and fibrous components of the pulp and periodontal ligament
2. Analyze the changes that occur within the pulp, enamel, dentin, and the periodontal ligament during aging
Demonstrate the knowledge of cellular histology
Evaluate the histology and development of the oral cavity
1. Examine the histology of the oral mucous membrane
2. Differentiate the cellular and ductal components of the major salivary glands
3. Synthesize the histological development of the fibrous and bony components of the temporomandibular joint
Assess embryological development
1. Differentiate histologically the pre-eruptive and post eruptive phases of tooth movement
2. Synthesize the embryological and histological development of the maxilla and mandible
3. Analyze the embryological development of the oral cavity
4. Contrast normal versus abnormal embryological development of the oral structures
