|---|
| acellular cementum | covers anatomical root |
| alveolar process | portion of the jaw that supports the teeth |
| alveolus | bony socket where the tooth fits |
| cementum | softer than enamel or dentin, 50% inorganic 50% organic, produced by cementoblasts |
| dentin | forms largest portion of crown and root |
| enamel | most mineralized and hardest tissue in the body, produced by ameloblasts |
| incisive papilla | bulge of tissue at midline of hard palate posterior to central inisors |
| pulp | nourishing and sensory part of the tooth, responds on to pain |
| anatomical crown | whole crown of tooth covered by enamel whether erupted or not |
| clinical crown | only that part of crown seen superior to gingival margin |
| cusp of carabelli | 5th cusp on maxillary first molars |
| mamelons | incisal ridges on incisors after eruption, if they remain there is no attrition |
| nonsuccedaneous | permanent teeth without primary predecessors- permanent molars |
| mixed dentition period | 6-12 yrs old |
| tooth shade is dependent on? | mineralization and thickness of enamel, skin pigmentation. whether it is primary or permanent |
| point angle | where 3 surfaces meet |
| line angle | where 2 surfaces meet |
| fusion | when two adjacent tooth germs unite to form one large crown |
| gemination | single tooth germ splits to form two completely separated crowns |
| dens in dente | tooth within a tooth-most common is max lateral |
| enamel pearls | excess enamel on surfaces of teeth apically to the CEJ- freq found in bi and trifurcations |
| Hutchinson's Incisors | result of prenatal syphilis |
| microdontia | abnormally small teeth-peg lateral |
| mulberry molars | irregulary shaped with poorly formed cusps with congenital syphilis |
| attrition | wearing away through contact of its functioning surfaces |
| overbite | vertical overlap if max and mand incisors |
| physiologic rest | no teeth are in contact |
| which anterior tooth can have more than one root? | mandibular canine |
