| Proximal contact areas | The ________________ of the teeth are the areas on the surfaces of the teeth where the proximal surfaces touch one another. |
| Offer support and anchorage to one another and resistance to displacement from traumatic forces. | What do the proximal contact areas help do? |
| Proximal contact areas | Are located on the mesial and distal surfaces of each tooth and at the widest portion and the greatest curvature. |
| Interproximal spaces | Are triangular shaped spaces between the teeth that formed by the bone on one side and the proximal surfaces and their contact area on the other side. |
| Papillary gingiva or interdental papilla | The interproximal of the teeth is filled with what tissue? |
| Interdental space | Space between teeth provides a place for a bulk of bone, thus affording better anchorage and support. |
| Cervical embrasure | Embrasure or spillway located cervical to the contact area of the teeth. |
| Embrasure | Open space between the proximal surfaces of two teeth where they diverge bucally, lingually, labially, or lingually and occlusally from the contact area. |
| Facial and lingual contours | Affords the correct amount of frictional massage to the gingiva by directing food off the teeth and against the gingiva at a proper angle. |
| Gingival inflammation, periodontal disease, or tissue recession. | Food packed into the crevices can cause? |
| Maximum cleaning of the cheeks and lips | The facial height of contour allows for? |
| Mesiodens | Supernumerary teeth that arising in the midline of the maxillae. |
| 9:1 | Maxillary supernumerary teeth outnumber mandibular. |
| Distomolars | Fourth molars that are located distally to the maxillary third molars. |
| Odontoma | A tumorous anomaly of calcified dental tissues. |
| Dens in dente | A developmental variation thought to occur when the outer surface of the tooth crown invaginates or turns itsself inward before mineralization. |
| Dilacerated tooth | A tooth that has a sharp bend or curve in the root or crown. |
| Dwarfed roots | A condition in which the roots of the teeth are extremely short in comparison with their crowns. |
| Gemination | An anomaly that arises when a tooth attempts to divide itsseld or partially twin itsself by splitting its tooth germ. |
| Fusion | Occurs when two adjacent tooth germs unite. |
| Hypercementosis | Is the deposition of excessive amounts of secondary cementum. |
| Cementoma | A form of hypercementosis that is also associated with localized destruction of the bone. |
| Enamel Pearls | Small masses of excess enamel on the surface of the teeth located apically to the cementoenamel junction. |
| Hutchinsons Incisors | Notched incisors, called screwdriver shaped, that form as a result of prenatal syphilis. |
| Enamel hypoplasia | Leaves small pits or grooves at different levels in the crown. |
| Enamel Fluorosis | A discoloration of enamel due to too much fluoride in the tooth structure. |
| Amelogenisis imperfecta | Related to hypocalcification but one that is hereditary rather then acquired. |
| Maxillary incisors | Which anterior incisors are much wider mesiodistally than faciolingually? |
| Central incisors | Which incisors, centrals or laterals, have tha great crown to root ratio? |
| Mandibular centrals are mandibular laterals | Which incisors are nearly identical? |
| Mesial | In general, does the cervical line curve more incisally on the mesial or the distal surface? |
| Maxillary | Which has more developed lingual marginal ridges the maxillary or mandible? |
| Distal | On incisors, which incisal line angle is more rounded, mesial, or distal? |
| Mandibular | Which incisor has its incisal edge worn on the labial side, maxillary or madibular? |
| Mandibular lateral | Which mandibular incisor is longer? |
| Maxillary | Which canine has more distal convexity? |
| Inside | Which is more concave, the inside or outside of a football helmet? |
| Mesial | On canines, which surface is least convex, mesial or distal? |
| Maxillary first premolars | Which premolars are most likely to have two roots? |
| Mandibular second premolar | Which premolar is most likely to have three cusps? |
| Maxillary first premolar | Which premolar is most likely to have a well defined mesial marginal groove? |
| First | Which molars, first or second, are most likely to have five cusps? |
| Distal | Name the smallest of the five cusps of a mandibular first molar. |
| Mesiolingual | The fifth cusp of a maxillary first molar is located on what other cusp? |
| Second | The roots are closer together on a first or second molar? |
| First | The roots are longest on a first or second molar? |
| Mandibular first molar | Which molar is most likely to have three buccal cusps? |
