Oral Histology Workbook

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
