|
Definition
|
|
Term
| when does resorption begin? |
|
Definition
| at least a year prior to exfoliation |
|
|
Term
|
Definition
| a dissolving away of the root by osteoclastic activity |
|
|
Term
| why do primary teeth resorb? |
|
Definition
| possibly due to the pressure of permanent teeth or possibly due to a chemical or cell signaling by the developing permanent tooth |
|

|
Definition
|
|
Term
|
Definition
| the tooth pushes through the mucous membrane cover of the alveolar process and into the oral cavity |
|
|
Term
| when is active eruption complete? |
|
Definition
| when the tooth contacts its opposing tooth or teeth in the opposite arch |
|
|
Term
| what is passive eruption? |
|
Definition
| the continuing process of adaptation of a tooth to changing relationship with opposing teeth-- after active eruption has ended |
|
|
Term
| what are three examples of passive eruption? |
|
Definition
(1) attrition
(2) tooth loss
(3) fracture of opposing teeth |
|
|
Term

|
|
Term
| what is the Nasmyth's membrane? |
|
Definition
| a keratinous, membrane-like cuticle that envelops the anatomical crown when the tooth erupts; it abrades away rather quickly |
|
|
Term
