|---|---|
| Amelogenesis imperfecta | A hereditary form of enamel hypocalcification |
| Ankylosis | Fusion of the cementum of a tooth with alveolar bone |
| Anodontia | No teeth at all present in the jaw |
| Bicuspids | Same as premolars |
| Cementoma | Cementum tumor at root tip that destroys surrounding bone |
| Concresence | Two adjacent teeth or roots that fuse by their cementum |
| Congenital | Occurring at or before birth; may or may not be hereditary |
| Congenitally missing | Condition of having never been developed |
| Conical tooth | A supernumerary tooth that is cone shaped |
| Curve of Spee | Anatomic line beginning at the tip of the canines and following the buccal cusps of premolars and molars when viewed from the buccal aspect of the first molars |
| Cusp of Carabelli | Fifth lobe of a maxillary first molar |
| Dens in dente | An invagination of the outer surface of the tooth crown turning inward on itself |
| Dental caries | damage to a tooth that can happen when decay-causing bacteria in your mouth make acids that attack the tooth’s surface, or enamel. Also called tooth decay, decay, or cavities. |
| Dentinogenesis imperfecta | Hereditary imperfect dentin formation |
| Developmental grooves | Fine depressed lines in the enamel of a tooth that mark the union of the lobes of the crown. |
| Developmental lobes | Major growth centers of a tooth |
| Dilacerated tooth | tooth with sharply bent root |
| Distomolar | fourth molars |
| Dwarfed root | tooth with very short roots in comparison with the crown |
| Edentulous | An area without the presence of teeth |
| Enamel dysplasia | Abnormality of enamel growths |
| Enamel Fluorosis | A form of enamel hypocalcification where enamel is discolored because of an excess of fluoride in the tooth structure |
| Enamel hypocalcification | Enamel that is not as dense as regular enamel |
| Enamel hypoplasia | Enamel that is thin or pitted |
| Enamel Pearls | Small rounded elevations of enamel, usually developing in the bifurcations or trifurcations of teeth; considered abnormal structures. |
| Eruptive stage | Period of eruption from the completion of crown formation until the teeth come into occlusion |
| Exfoliation | Shedding or loss of primary tooth |
| Extrinsic | Originating outside a structure |
| Familial tendency | When an anomaly occurs more frequently than usual in one family |
| Flexion | A bend or a twist in the root, not involving the crown. |
| Fusion | Two teeth that fuse at their dentin while they are developing. Also, a term used for the process of formation of the hard and soft palates. |
| Gemination | A tooth that partially or fully divides into tow teeth while developing |
| Hereditary | Inherited through the genes of parents |
| Hutchinson’s Incisors | Notched central incisors that develop as a result of congenital syphilis |
| Hypercementosis | Increased thickness of cementum, usually seen at the apex of the root. |
| Hyperdontia | More than the usual number of teeth |
| Impacted | Describing teeth not completely erupted ghat are fully or partially covered by bone or soft tissue. |
| Intrinsic | Lying entirely inside a structure |
| Macrodonia | teeth that are too large for the jaw |
| Mesial drift | Phenomenon of permanent molars continuing to move mesially after eruption |
| Mesiodens | Supernumerary teeth arising in the midline of the maxilla |
| Microdontia | Teeth that are too small for the jaw |
| Mixed Dentition | State of having primary and permanent teeth in the dental arches at the same time. |
| Mottled enamel | Enamel that has been discolored by excess fluorides in naturally fluoridated water or by excessive fluoride intake |
| Mulberrry Molars | Molars with multiple cups; caused by syphilis |
| Mutans streptococci | an anaerobic, gram-positive coccus commonly found in the human oral cavity and is a significant contributor to tooth decay. |
| Lactobacilli | any Gram-positive rod-shaped bacterium of the genus Lactobacillus, which ferments carbohydrates to lactic acid. |
| Odontoma | A tumor made up of enamel, dentin, cementum and pulp |
| Preeruptive Stage | Period when the crown of the tooth is developing. |
| Posteruptive stage | Period of eruption from the time the teeth occlude until they are lost and characterized by occlusal wear of teeth and compensating eruption |
| Primary dentition | First set of teeth; baby teeth; milk teeth; deciduous teeth |
| Resorption | Physiologic removal of tissues or body products, as of the roots of deciduous teeth or of some alveolar process after the loss of permanent teeth. |
| Rudimentary lobe | Small underdeveloped lobe of a tooth; less than a minor lobe. |
| Supernumeraries | Extra teeth in the jaw |
| Tetracycline staining | Discolored teeth that result when an expectant mother or a young child takes the antibiotic tetracycline while tooth crowns are still developing |
| Tooth germs | soft tissue that develop into a tooth |
| Tubercle | very small rudimentary supernumerary |
| Turner’s tooth | Hypocalcification of a single tooth |
