Study Notes
Tooth Anatomy
- The clinical crown refers to the part of the tooth visible above the gingiva; any unerupted portion is not included.
- If an entire anatomic crown remains unerupted, only the visible part is the clinical crown, while the rest forms part of the clinical root.
- Tooth structure includes coronal, cervical, and apical areas.
Root and Support Structure
- The root is anchored in the alveolar process, a bony section of the dental arch.
- The bony socket for the tooth is called the alveolus.
- Teeth in the upper jaw are maxillary; in the lower jaw, they are mandibular.
Tooth Tissues
- Four primary tooth tissues: enamel, dentin, cementum, and dental pulp.
- Enamel, dentin, and cementum are hard tissues; dental pulp is soft tissue.
Dentin Types
- Reparative dentin forms quickly in response to injury such as decay or fractures.
- Tertiary dentin can develop from various traumas, including cracked teeth and deep restorations.
Functions of Teeth
- Tooth functions include cutting, holding, and grinding food based on individual shape, size, and location.
Tooth Surface Junctions
- A line angle occurs where two surfaces of a tooth meet.
- For instance, the union of buccal and occlusal surfaces is described as the bucco-occlusal line angle.
- Point angles are where three surfaces intersect, such as the mesiolabioincisal point angle.
Tooth Growth and Development
- Teeth develop from lobes, typically four or more growth centers.
Posterior Teeth Features
- The most prominent features on posterior teeth are the cusps, formed by four ridges, with triangular ridges being the main ridges running from the cusp tip to the occlusal surface.
Anterior Teeth Characteristics
- Anterior teeth have two developmental grooves on the labial surface separating three lobes, plus a fourth lobe, the cingulum, on the lingual surface.
Occlusal Features
- A transverse ridge is formed by the union of two triangular ridges—one buccal and one lingual—across a posterior tooth's occlusal surface.
Occlusion and Malocclusion
- Occlusion defines the relationship between maxillary and mandibular teeth in a closed jaw position.
- Malocclusion can affect teeth, joints, and surrounding muscles, potentially leading to periodontal issues.
Types of Occlusion
- Centric occlusion occurs with maximal stable contact between upper and lower teeth, serving as a standard for normal occlusion.
- Normal occlusion involves the lingual cusps of maxillary teeth fitting into the central fossae of mandibular teeth, facilitating effective food grinding.
- Functional occlusion refers to tooth contact during biting and chewing.
