Course Learning Outcomes
  1. Describe and define the oral cavity proper, primary and adult dentitions, tooth surfaces, landmarks and anatomical features each tooth.
  2. Describe the process of tooth development, exfoliation, resorption and occlusion of primary and adult dentitions.
  3. Explain the relationships within the gingival unit, supporting structures of the teeth (periodontium) and tooth anomalies related to morphology.

  33. Describe each of the three permanent maxillary molars from all five aspects including the roots.
  34. Describe the three permanent mandibular molars from the five anatomical aspects including the roots.
  35. Explain the root location differences between maxillary and mandibular molars and why this is important.
  36. Identify anatomical root variations, cej curvature, furcations, developmental concavities for effective instrumentation adaptation.
