Talon cusp
64
talon cusp
65
When treating/removing a talon cusp, how do we do it?
We gradually shave it down. Dont want to do it all at once because there is pulp horn! Gradually do it allowing for reaparative dentin to form at each session.
66
dens evaginatus
67
How do we treat dens evaginatus?
Same as a talon cusp! has a pulp horn too! pretty much the same thing as talon cusp but on posteriors
talon cusp :extra cusp on anteriors
Dens evaginatus: extra cusp on posteriors
68
dens evaginatus
69
dens invaginatus
70
Another term for dens invaginatus?
dens in dente
71
What is the problem patients may have with dens in dente/dens invaginatus?
it is a pit with only a small amount of dentin. It is very easy for food to get trapped in there and for a cavity to form.
