Oral Histology Workbook Quiz

Overview

• This workbook supports oral histology learning as part of Oral Dental Sciences
• It complements pre-recorded oral histology sessions
• The workbook is self-directed, but recommended for foundational knowledge in Years 1, 2, 3 and future careers.
• Answers are not provided; use resources and seek peer assistance. Learning to find answers is encouraged.
• All oral histology topics are assessed in the summative assessment.
• Case study sessions are scheduled to consolidate learning.

Resources to Support Learning

• Textbook: Berkovitz et al., 2018 - Oral anatomy, histology, and embryology.
  • Chapters include: Enamel, Dentine, Pulp, and Cementum
• Other Articles and Resources:
  • Multiple journal articles and online resources are referenced, providing detailed information on specific aspects of enamel, dentine, pulp, and cementum. These include structures, functions, and related defects.
• YouTube videos are referenced for learning support, covering amelogenesis and enamel structure, as well as dentinogenesis and structure.

Composition Comparison Table

• This table compares the mineral and organic composition, water content, embryonic origins, formation cell lifespan, structural features and functions of enamel, dentine, pulp, and cementum.

Histology of Enamel

• Diagram to demonstrate histological structure and arrangement of enamel for an incisor crown is required, including enamel rods, interrod, and crystallites
• Structural characteristics and their link to enamel function are explained in relation to enamel’s ability to resist or be susceptible to dental caries.

Histology of Dentine

• A diagram is required, illustrating the structure and contents of dentine tubules. Features include peritubular dentine, intertubular dentine, odontoblast process, periodontoblastic space, and fluids.
• Structural features and function are described in relation to dentine’s impact on caries progress, in comparison to enamel's characteristics.
• The three types of dentine (primary, secondary, and tertiary) are compared and contrasted.

Histology of Pulp

• Diagrams are required, outlining the pulp locations within the teeth: upper central permanent incisor, lower second permanent molar, and upper first premolar.
• Pulp composition is detailed and labeled in diagram B. Components include odontoblasts, cell-free zone, cell-rich zone, and artery, among others.
• The composition, structure, and function of pulp tissues' components, e.g. blood vessels, lymph vessels, nerve supply, odontoblasts, fibroblasts, defense cells, undifferentiated cells, and ground substance are analyzed.
• The structural relationship between dentine and pulp, particularly concerning the odontoblast processes extending into dentine tubules, is discussed.
• The impact of pulp location relative to caries progression.

Histology of Cementum

• The embryonic origin of cementum is described, including four categories, and the cells responsible for cementogenesis are listed.
• A table compares the mineral content, critical pH, and functions of enamel, dentine, cementum, and bone.
• Two types of cementum fibres (cellular and acellular) are presented along with their location and function on the teeth.
• A visual representation is needed, illustrating and labeling tooth features.
• Functions of acellular and cellular cementum, in relation to distribution on the root, and the significance of the gap when the CEJ is exposed.
• Possible configurations for the cemento-enamel junction are to be sketched.
