Who said:the fracture strength of calcium hydroxide-filled immature teeth will be halved in about a year? i.e. from in vitro study–long term Calcium hydroxide weakens teeth

Who said if you lose vitality in an immature tooth that is not fully formed, there is increased risk of cervical fracture?
Cvek 1992

cervical fracture?

Three ways to decreases chance of ankylosis after a tooth has received trauma
- splint should only be on for one to two weeks
- endo should be done 7-10 days after trauma
- leave CaOH2 in for one month
Three types of resorption. Which is most common complication for avulsed teeth?
Surface, replacement, inflammatory. Replacement (bone fills in)-mos common complication for avulsed teeth.
What clamp to use on primary molars?
13a
Who showed that pulpotomy was very effective in eliminating pain initially and over 28 days. The intracanal medicament used (Cresatin, CMCP, Eugenol ZOE, Saline or dry cotton) was irrelevant and didn’t effect the results
Hasselgren and Reit 1989
Hasselgren and Reit 1989
pulpotomy
Showed that pulpotomy was very effective in eliminating pain initially and over 28 days. The intracanal medicament used (Cresatin, CMCP, Eugenol ZOE, Saline or dry cotton) was irrelevant and didn’t effect the results
Huang 2013 (regeneration)
Showed that human stem cells from apical papilla can regenerate dentin-pulp complex like tissue.
Who showed that human stem cells from the apical papilla (scap) can regenerate dentin-pulp complex like tissue?
Huang 2013
three major components for tissue engineering:
Cell source, physical scaffold, signaling molecules
what is the tissue like in an internal cervical resorption lesion?
fibrovascular tissue with clastic cells adjacent to the dentin (can’t get past the unmineralized predentin that surrounds the pulp) (Heithersay 1999)
predisposing factors for external cervical resorption? according to? reviewed by?
1 is ortho, #2 is trauma and bleaching. Heithersay (1999), reviewed by Patel 2009
How much of root surface must be damaged to cause replacement resorption? Says who?
Andreasen, 20%
cause of resorption? says who?
Trope. Damaged protective layer (predentin internally or cementum externally) with subsequent inflammation from noxious stimuli.
Prognosis of permanent teeth with internal resorption? According to whom?
Turkun 1997: >90% with one week calcium hydroxide and warm gutta percha if no external perforation. 25% with perforation (1 in 4).
Who said that you can differentiate external from internal resorption because you can trace the root canal through it, and it moves on shift shots?
Gartner and Mack 1976
Gartner and Mack 1976 resorption?
you can differentiate external from internal resorption because you can trace the root canal through it, and it moves on shift shots
Medication for avulsion?
Doxycycline bid for 7 days, unless <12 years old, then penvk for 7 days.
Why use EDTA in regeneration? According to whom?
EDTA improves adhesion of stem cells to dentinal walls. Galler 2011
Who had a 95% success rate with apical closure when necrotic immature teeth were treated with calcium hydroxide?
Cvek 1972
Cvek 1972
95% success rate with apical closure when necrotic immature teeth were treated with calcium hydroxide.
How do we define fractures now?
Uncomplicated (no pulp exposure) v. Complicated (pulp exposure)
