VT Dental Terms
| Term | Definition |
|---|---|
| Alveolus | The socket in the bone in which the tooth fits |
| Apex | Most terminal protion of the root |
| Apical Foramen | Small opening found at apex of the root allowing nerves and vessels to enter tooth |
| Cementum | Bony substance covering the roots that assists with holding the tooth in place |
| Cemento-enamel Junction | Where cementum meets the enamel. |
| Crown | Portion of the tooth above the gumline |
| Dentin | Dense bone-like material underlying the enamel making up the bulk of the tooth |
| Enamel | Outer covering of the crown - hardes substance in the body |
| Gingiva | Fibrous tissue covered by mucosa (gum tissue) |
| Gingival Sulcus | The groove or pocket formed by the unattached portion of the gingiva |
| Incisive Papilla | Lies caudal to upper incisors - associated with scent recognition |
| Lingual salivary gland | Lies caudal to the the mandibular 1st molar in cats |
| Mandibular salivary gland | Lies caudal to the mandibular lymph nodes |
| Mandibular Symphysis | Rostral attachment of both mandibles by a strong fibrous joint |
| Periodontal Ligament | Fibers that hold the tooth in the socket by connecting the cementum to the bone |
| Pulp Cavity | Contains nerve and blood supply of tooth |
| Pulp Chamber | Soft tissue system inside the crown of the tooth |
| Root Canal | Soft tissue system in side the root of the tooth |
| Root | Portion of the tooth below the gumline |
| Incisors | Small cutting teeth used for nibbling or grooming |
| Canines | "Fangs" designed for grasping and tearing with great force |
| Premolars | Larger tearing or shearing teeth |
| Molars | Larger teeth meant for grinding, not used for this as much in carnivores |
| Carnassials | The primary shearing teeth - upper 4th premolar and lower 1st molar |
| Deciduous | Baby teeth - provide a pathway for the eruptionof the permanent teeth |
| Normal occlusion | Lower canines - mesial to upper canines Upper incisors - rostral to lower incisors Upper carnassial teeth - lateral to lower carnassial teeth |
| Anterior cross-bite | A normal occlusion except one or more of the incisors are misaligned |
| Posterior cross-bite | Maxillary premolars - lingual to mandibular premolars or molars |
| Level Bite | The incisors meet (Normal in cats) |
| Brachygnathism | Overshot - lower jaw too short |
| Prognathism | Undershot - lower jaw too long |
| Wry Mouth | Elongation of half the jaw |
| Supernumerary Teeth | Extra permamnent teeth or deciduous teeth |
| Retained deciduous teeth | Retained baby teeth after eruption of permanent teeth |
| Gemination | Partial splitting of a tooth - looks like two crowns with common roots |
| Abrasion | Loss of tooth substance from wear and tear |
| Attrition | Loss of the tooth substance from wear due to malocclusin of teeth |
| Abscess | Accumulation of purulent material |
| Apical | Direction toward the root tip or away from the incisal or occlusal surfaces |
| Buccal | Surface of the tooth toward the cheek (premolars and molars only) |
| Calculus "Tartar" | Salivary minerals and plaque that have hardened on the tooth |
| Coronal | Toward the crouwn of the tooth |
| Distal | Tooth surface away from te rostral midline |
| Furcation | The area where the roots of multirooted teeth meet |
| Halitosis | Foul odor from the mouth |
| Incisal | Coronal surface of the incisors |
| Labial | Surface of the tooth facing the lips (incisors only) |
| Lingual | Surface of the tooth facing the tongue (lower only) |
| Mesial | Tooth surface facing toward the rostral midline |
| Occlusal | Flat grinding surface of the molars |
| Palatal | Surface of tooth facing the hard palate (upper only) |
| Periapical | Around the apex of the tooth |
| Periodontium | The supporting structures of the tooth which include the gingiva, cementum, periodontal ligament and alveolar bone |
| Saliva | Enzymatic secretion in the mouth from glands, pH 7.5, promotes the deposition of plaque |
