Study Notes
Occlusion
- Understanding the alignment and interaction between different teeth during biting and chewing.
Anterior Teeth
- Refers to the front teeth: incisors and canines, important for aesthetics and biting.
Posterior Teeth
- Refers to the back teeth: premolars and molars, crucial for grinding food.
Maxillary Arch
- The upper dental arch, housing the maxillary teeth.
Mandibular Arch
- The lower dental arch, containing the mandibular teeth.
Anatomy of Tooth
- Clinical Crown: Visible tooth portion above the gum line.
- Root: Tooth portion embedded in the alveolar process, covered by cementum.
Parts of Tooth
- Pulp: Innermost tissue with blood vessels, lymphatics, and nerves.
- Cementum: Bone-like tissue covering the tooth root.
Tissues of the Tooth
-
Enamel:
- Forms the anatomic crown, hardest tissue in the body.
- Cannot remodel or repair.
-
Dentin:
- Makes up most of the tooth mass, softer than enamel, sensitive when exposed.
-
Cementum:
- Covers the tooth's root, joins enamel at the cemento-enamel junction, anchors teeth in sockets.
-
Pulp:
- Contains blood vessels and nerves, facilitates the exchange between pulp and dentin.
Surfaces of Teeth
- Each tooth has five surfaces:
-
Facial Surface:
- Divided into labial and buccal surfaces.
- Labial Surface: Front surface of incisors and canines facing the lip.
- Buccal Surface: Surface of premolars and molars facing the cheek.
- Lingual Surface: The side of the tooth facing the tongue.
- Mesial Surface: Side of the tooth closest to the midline of the face.
- Distal Surface: Side of the tooth farthest from the midline.
- Occlusal Surface: The chewing surface of posterior teeth.
- Incisal Edge: Cutting edge of anterior teeth.
- Palatal Surface: Inner surface of the maxillary teeth facing the palate.

Facial Surface:
