| Definition | Term |
| The whole root | Anatomical Root |
| A small linear depression on the surface of a tooth. | Groove |
| Facial, Middle, Lingual | Proximal surface divided into thirds |
| An elevation which extends in a mesial and distal direction from the cusp tip. Cusp ridges form the buccal and lingual margins of the occlusal surfaces of the posterior teeth | Cusp Ridge |
| Fibrous connective tissue surrounds/attaches root of tooth(cementum) to Alveolar bone | Periodontal Ligament |
| 3 surfaces come together | Point Angles |
| A fault occurring along a developmental groove caused by incomplete or imperfect joining of the lobes. Wehn two fissures cross they form a pit | Fissure |
| hole in bottom of root(apex) where blood/nerve enters tooth | Apical Foramen |
| Formed by the junction of the linguoincisal surfaces of an anterior tooth. This edge does not exist until occlusal wear has created a surface linguoincisally. This surface forms an angle with the labial surface. | Incisal edge |
| Mesial, MIddle, Distal | Facial surface divided into thirds |
| Elevated crests or rounded folds of enamel which form the mesial and distal margins of the occlusal surfaces of the posterior teeth and the lingual surfaces of the anterior teeth. Rim of the tooth where sides meet top. Borders around crown | Marginal Ridges |
| the incisal portion of a newly erupted anterior tooth | Incisal ridge |
| softest tissue in crown/root; blood/nerves supplied here | Pulp |
| a relatively broad, deep angular valley in the central portion of the occlusal surface of a mandibular molar. | Central Fossa, Mandibular molars |
| A rounded or angular depression of varying size on the surface of a tooth | Fossa |
| A rounded or conical prominence on the incisal ridge of a newly erupted incisor. They are usually three in number, and soon disappear as the result of wear. | Mamelon |
| large area of soft tissue in crown | Pulp Chamber |
| A linear elevation on the surface of a tooth. It is named according to its location or form. | Ridge |
| Elevated prominences on the occlusal surfaces of maxillary molar extending obliqely from the tips of the mesiolingual cusp to the distobuccal cusp | Oblique Ridges |
| Provides attachment for periodontal ligament; soft tissue that covers root | Cementum |
| Permanent teeth that replace primary(incisors, canines, premolars) | Succedaneous teeth |
| An indistinct linear depression, irregular in extent and direction, which does not demarcate major divisional portions of a tooth. These often give the occlusal surface a wrinkled appearance. | Supplemental Groove |
| Dentin meets enamal in crown(internal line) | Dentoenamel junction |
| The visible part of root | Clinical Root |
| Cementum meets enamel | Cementoenamel Junction |
| to support/suspend tooth in the socket(alveolus) | Funtion of Perio.Lig |
| cementum, Periodontal ligament, alveolar process, gingival | The periodontium |
| A groove formed by the union of two loves during development of the crown. | Developmental groove |
| Made up of the triangular ridges of a buccal and lingual cusp which joion to form a more or less continuous elevation extending transversely across the occlusal surface of a posterior tooth. Run from 1 cusp to another on post. teeth | Transverse Ridges |
| 4 anterior teeth(used for cutting food) | Incisors(central,lateral) |
| The visible part of crown | Clinical Crown |
| a pronounced elevation on the ooclusal surface of a tooth terminating in a conical or rounded surface; any crown elevation which begins calcification as an independent center. A cusp is considered to have an apex and four ridges | Cusp |
| before the molars(2-3 cusps) | Premolars |
| 32 teeth total(8 incisors, 4 canines, 8 premolars, 12 molars | Permanent Dentition |
| outer root covering | Cementum |
| an elongated valley in the surface of a tooth formed by the inclines of adjacent cusps or ridges which meet at an angle | Sulcus |
| A comparatively shallow pyramid-shaped depression on the occlusal surcaes ot hthe posterior teeth located just within the confines of the mesial and or distal marginal ridges | Triangular Fossa |
| The "fifth" cusp located on the lingual surcae of amny maxillary first molars | Cusp of Carabelli |
| A developmental segment of the tooth. As lobes develpp they coalesce to form a single unit. | Lobe |
| a broad, shallow depression of varying size on the lingual surface of an incisor or cuspid. | Lingual Fossa |
| sides of tooth that make box(facial/lingual mesial/distal) | Axial Surfaces |
| 20 teeth total(8 incisors,4 canines, 8 molars) | Primary Dentition |
| Prominent elevations, trianglar in cross-section, extend from tip of cusp towar the central portion of the occlusal surface of a tooth. Ridges decend from tip of cusps and widen toward the central area of the occlusal surface | Triangular Ridges |
| A bulge or prominence of enamel found on the cervical third of the lingual surface of an anterior tooth | Cingulum |
| outer covering of crown | Enamel |
| 2 surfaces come together and meet | Line Angles |
| Skinny areas of soft tissue in root | Pulp canals |
| Apical, Middle, Cervical | Root divided into thirds |
| the whole crown | Anatomical Crown |
| 2nd layer found in crown and root | Dentin |
| a relatively broad, deep angular valley in the central portion of the occlusal surface of a maxillary molar. | Central Fossa, Maxillary molars |
