Study Notes

DENT1001 Dental Anatomy

  • Course: Dental Anatomy
  • Instructor: Dr. Ä°zim Türker Kader
  • Date: 13.10.2024
  • Core Textbooks:
    • Wheeler's Dental Anatomy, Physiology, & Occlusion (10th Edition)
    • Management of Temporomandibular Disorders and Occlusion
    • Wheeler's Atlas of Tooth Form
  • Additional Textbooks:
    • Woelfel's Dental Anatomy
    • Textbook of Dental Anatomy, Physiology & Occlusion

Learning Outcomes

  • Students will be able to compare the thirds of the crown and roots.
  • Students will be able to distinguish line and point angles.
  • Students will be able to explain the measurement of teeth from different aspects.
  • Students will be able to summarize morphological features.
  • Students will be able to compare crown morphology of anterior and posterior teeth.

Division into Thirds & Anatomical Crown Morphology

  • Division into Thirds: Teeth are divided into thirds for precise description, naming specific locations like proximal contacts.
  • Line Angles: Formed by the junction of two crown surfaces. Names are derived from combining surface names, modifying "al" to "o" in the first. Follow this order: mesial, distal, facial/lingual, and occlusal/incisal.
  • Point Angles: Formed where three surfaces meet. The name combines the surfaces and are used to describe specific landmarks along the tooth.

Comparative Tooth Anatomy

  • Overall: Study of tooth structure similarities and differences. The crowns and roots of teeth are divided into thirds.
  • Measurement: Numerous measurements are described (e.g., lengths, diameters, curvature).
  • Terminology: Precise terminology is essential (e.g., line angles, point angles). Multiple figures and examples of teeth are referenced for illustration throughout the study notes.
  • Illustrations: Many figures and diagrams are referenced to demonstrate anatomical landmarks (e.g., different views of teeth, diagrams of tooth division)

Anatomical Crown Morphology

  • Landmarks: Precise descriptions of various elevations (cusps, tubercles) and depressions (fossae, sulci) on tooth crowns.
  • Terminology: Detailed explanations and examples of specific morphological features.
  • Measurements: Table of measurements for teeth of average sizes. Specific directions for taking those measurements.
  • Features: Definitions and locations of features like ridges, marginal ridges, fossae, sulci, and fissures.
