|
In primary molars, what can we say about enamel? |
The enamel is relatively thin and has consistent depth.
(Permanent teeth's enamel is more thick in the cusp area and thinner at the cervical line. |
|
|
In primary molars, what can we say about the dentin? |
Dentin thickness between the pulp chambers and enamel us limited. |
|
|
Dentin thickness between the pulp chambers and enamel us limited especially in what kind of primary tooth? |
The primary first molars |
|
|
On permanent molars, which pulp horn is more built up? |
The Mesial pulp horn |
|
|
Pulp horns are really_____________on primary molars. |
High-->so need to take care of decay fast so you can avoid a pulpatomy. We don't do root canals on children since the roots will reabsorp anyway. |
|
|
Primary molars have large___________which means more bleeding. |
Pulp chambers |
