Study Notes
Overview
- This workbook supports oral histology learning, part of Oral Dental Sciences
- It's a self-directed resource, not mandatory but recommended for foundational knowledge
- The workbook helps students find answers using resources like lectures and articles
- Assessment for oral histology, including pulp, is part of the summative assessment
- Case study sessions will support learning
Resources to Support Learning
- Textbook reading (Berkovitz et al. 2018): Oral anatomy, histology, embryology, dental radiography
- Nanci & Ten Cate (2018): Oral histology, development, structure, and function
- Articles: Enamel structure, enamel defects, dentin structure, pulp functions/responses, and cementum
- Online videos and virtual labs for amelogenesis, dentinogenesis, and enamel/dentin/cementum structure
- Digital histology labs for cementum
Composition Comparison Table
- Compares enamel, dentine, pulp, and cementum
- Shows mineral content, organic content, water content, embryonic origin, formation cells, structural features for each tissue
- The table looks at functions and notes on each tissue
Histology of Enamel
- Diagram of incisor crown enamel structure; identify enamel rods, interrod, enamel crystallites
- Structure of enamel links to function, relate features to function
- Description for incremental lines, enamel tufts, enamel spindles, perkymata, Hunter-Schreger bands, Stria of Retzius, lamellae
- Components of enamel, how they make it susceptible and resistant to caries
- How might the components impact caries management?
Histology of Dentine
- Diagram of the dentin tubules, includes peritubular dentine, intertubular dentine, odontoblast process, periodontoblastic space, and fluid
- Brief description for each of the structural features of dentine; incremental lines, dentinal tubules, interglobular dentine, sclerotic dentine, dead tracts, and granular layer of tomes
- Compare and contrast three types of dentine (primary, secondary, tertiary)
- Diagram of relationship between dentin, pulp, and odontoblasts
- Structures of dentin, and how they make it softer than enamel
- Impact of softer structure on caries progression
- How dentine carries out its functions (protection, support, repair, feel pain)
Histology of Pulp
- Diagrams showing pulp chamber, root canals, and apical foramen for upper central incisors, lower second molar, and upper premolar
- Diagrams illustrating pulp components (pulp horn, coronal pulp, nerve trunk, bifurcation zone, odontoblasts, cell-free zone, cell-rich zone, artery, root pulp, odontogenic zone)
- Table linking composition, structure, and function of pulp (blood vessels, lymph vessels, nerve supply, odontoblasts, fibroblasts, defense cells, undifferentiated cells, fibers, ground substance)
- Structural relationship between dentine and pulp
- Impact of pulp location on function when inflamed
Histology of Cementum
- Embryonic origin of cementum
- Cells involved in cementogenesis
- Table comparing composition of enamel, dentine, cementum and bone
- Types of cementum (cellular and acellular), location, and functions
- Diagrams showing acellular cementum, cellular cementum, dentine, alveolar bone, periodontal ligament, cemento-enamel junction, cementoid, cementocytes, cementoblasts, odontoblasts, fibroblasts, sharpey's fibres and intrinsic fibres
- Functions of acellular and cellular cementum
- Cemento-enamel junction configurations (3 possible configurations)
- Significance of the gap when the CEJ is exposed
