Study Notes
Tooth Morphology Workbook 1
- This workbook is used in conjunction with sessions on dentitions/tooth morphology.
- The workbook aims to help students meet intended learning outcomes, including:
- Recognizing the basic structure of a tooth and its surrounding tissues
- Listing the functions of the teeth
- Revising various dental notations for primary and secondary teeth
- Describing terminology for tooth morphology to identify landmarks
Structure of Tooth
- Dentine: Located in the space between the root and the bony socket; tough fibrous layer of connective tissue covering the bone of the upper and lower jaws. It's function needs to be described.
- Enamel: Found covering the root; embedded within the dentine walls.
Tooth Parts
- The diagram of the tooth should be labeled with the following terms: Neck, Gingivae, Periodontal ligament, Dentine, Cementum, Root, Root canal, Alveolar bone, Pulp chamber, Enamel, Crown.
Dental Terminology
- Alignment: Arranging in a straight line.
- Alveolar Process: The bone of the maxilla that supports the teeth
- Apical Foramen: The opening in the root tip through which blood, nerve, and lymph pass.
- Atrophy: The gradual wasting away of tissue.
- Bifurcation: The point where two structures divide.
- Cusp: A peak on the surface of a tooth; lingual or palatal lobe found on incisor teeth.
- Cusp of Carabelli: An extra cusp found on the mesio-palatal surface of some first maxillary permanent molars.
- Diastema: Spacing between teeth.
- Disto-incisal angle: Point where the disto and incisal edges meet.
- Embrasure: Small space between the contact areas.
- Eminence: A bulge or protuberance.
- Fissure: A fault or a small opening. Usually found on the buccal or occlusal surfaces of teeth or on the developmental lobes.
- Fossa: A shallow depression.
- Incisal Edge: Biting edge of the teeth (used for cutting).
- Malocclusion: Abnormal arrangement of the teeth.
- Marginal Ridges: Enamel ridges on the mesial and distal edges.
- Neck of the Tooth: The portion of a tooth joining the crown and root.
- Oblique Ridge: A ridge that runs obliquely across the occlusal surface of molars.
- Occlusion: Relationship of upper and lower teeth when the jaws are together.
- Periodontal: Pertaining to the tissues that surround the tooth (including the gums).
- Pulp: The vital part of the tooth contained in the pulp chamber
- Ridge: Linear elevation on the tooth surface.
- Root Trunk: The part of the root between the cervix and the point of the roots.
- Transverse Ridge: A ridge that descends from the cusp tip to the central part of the occlusal surface.
- Tubercle: A rounded elevation on the surface of a tooth.
