ENDO:
Intraoral dental sinus: Parulis (made up of granulation tissues, AKA gumboil from chronic
abscess sinus/fistula) no tx other than ENDO, from chronic periapical abcess from necrotic tooth,
if it doesn’t drain then I and D
Most likely cause pulp necrosis after trauma to the tooth: Pulp hyperemia
perforation prognosis worst: below osseous crest then furcation
Doing endo which part of MX Incisors perforate (root curved disto-lingually)? Mesial
Doing endo which part of Mx PM perforate? Mesial
doing endo, which part of Mn M1 perforate: D of mesial canal then M of distal
contraindication in endo: recent MI, uncontrolled DM
contraindication of pulec/pulpo in: leukemia.
after RCT marked reduction in size in bone: 6 mt-1 year to make
Dentist restoring tooth with amalgam after RCT should place amalgam 3mm inside
Blood pigments, pulp hyperemia, internal resorption, cervical external resorption after
bleaching: red tinge, pulp necrosis: grey color, pulp calcification: yellow color
Percussion: presence of inflammation in PDL or not
Palpation: spread of inflammation to periodontium from PDL or not
EPT- responsiveness of nerves
Thermal test (hot & cold)- pulp vitality. Hot (irrev), cold (rev)
How do you differentiate between an endo/perio lesion: EPT
Differential diagnosis of acute periodontal abcess & acute periradicular abscess? EPT
in Periapical abscess: gram-negative obligate anaerobic tx: penv/amoxi +metro, clinda
reccurent abcess: e.fecalis + facultative anaerobes (amoxi+metro-strinct anaerobes), clinda
Patient with tooth that has sensitivity that lingers with thermal test, sinus tract, and positive to
percussion, what does the patient have? Irreversible pulpitis with chronic periapical abcess
Dx lingering pain to cold and sensitivity to percussion: irreversible pulpitis with Periapical
periodontitis
Dx not responsive to cold, not to percussion, and palpation is tender: necrotic pulp and
chronic apical periodontitis.
,Your going to do RCT for upper lateral with Periapical abscess for which of the following
possibility you have to take informed consent from the patient? (benefits, risks, prognosis)
1 Broken instrument
2 long term prognosis
3 perforation
4 ledge formation
Ans all of the above
Which teeth do you perform pulp evaluation on?
a. tooth only
b. tooth and neighboring tooth
C. tooth, neighboring teeth, contralateral tooth
d. tooth, neighboring teeth, opposing tooth
Ans C
Endodontic pain is characterized by all except:
Dull, aching pain
Sharp, shooting pain
Throbbing Pain
Electrical Pain
Ans D (galvanic shock)
Prolonged, unstimulated night pain suggests which of the following conditions of the pulp?
A. Pulp necrosis
B. Mild hyperemia
C. Reversible pulpitis
D. No specific condition
Ans A
The most important principal governing the location and outline of the lingual or occlusal
opening into the pulp chamber is:
1 preserving tooth structure
2. direct access along straight lines
3. complete removal of roof and pulp chamber
4. removal of all caries and defective restorations materials
ans 2
Apical detector is use for all of these except:
a. length of the canal
b. reduce uses of periapical rx for lengthening checking
c. detects accessory canals
d. dilacerations
Ans C and D
,a Periapical lesion was discovered 1.5 years after an uncondensed, single cone root canal
filling was placed in max central incisor. Two year after careful Periapical curettage, lesion
is larger than it was before surgery. Likely cause?
1.Systemic involvement
2.Inadequate curettage
3.Failure of resect apex
4.Undiagnosed perio lesion
5.Leakage from poorly filled canal
Ans 5
Best to test pulp status for newly erupted tooth with open apex
1 hot test
2 cold test
3 Electrical pulp test
4 percussion
Ans 4
Which can differentiate between acute apical abscess and acute periodontal abscess?
Palpation
Rx, Anesthesic test
Percussion
EPT
Ans 5
Avulse permanent tooth immediately comes to the clinic what is your first response?
A implant it
B take radiography
Ans: implant it, Then take x-ray (# 1 determining factor of prognosis of avulsed tooth is time, the
sooner the better, within 20 min is the best chance of survival of PDL)
Which of the following is the diameter, in millimeters, of a 21 mm long, #35 K-file at D16?
A- 0.35
B- 0.41
C- 0.67
D- 0.74
And C (assume 2% taper unless stated otherwise 0.35+(2%x16)=0.67 mm) =D1 +(2%x16)
During endo treatment dentist made a ledge what is the reason?
1-changing large file often
2-using small file
3-curved root
ans 1.
During the preparation of a Class II cavity, which of the following permanent teeth pulp
horns will be the most subject to accidental exposure?
A. Distofacial of a maxillary first molar
, B. Distofacial of a mandibular first molar
C Facial of a mandibular first premolar
D. Lingual of a mandibular first premolar
Ans C
Which root of the following is LEAST likely to form ledge on it
1 long
2 curved
3 short
4 narrow
Ans 3 (short, broad no calcification least likely)
for which factor is least likely to refer endo case
A. Dilacerations
B. Calcification
C. Inability to obtain anesthesia
D. Mesial inclination of molar
ans: D
which of the following nerve fibers of pulp are responsible for thermal conduction?
a) A beta
b) A delta
c) A beta and A delta nerve fibers
d) A alpha and A delta nerve fibers
e) C fibers& A delta
Ans E
EPT tends to be unreliable in young teeth since C fibers are more easily electrically
stimulated than A fibers. In Young teeth A fibers appear later than C fibers.
A) Both statements are TRUE.
B) Both statements are FALSE.
C) The first statement is TRUE, the second is FALSE.
D) The first statement is FALSE, the second is TRUE.
Ans D
Most important detail that would most affect the outcome of a fractured tooth
a) 48 hour delay of treatment
b) fracture being far away from apex
c) larger than normal pocket
d) infection
ans B
talking about fractures here, not avulsions (where time and medium of storage are most
important) fracture line will determine tx and also prognosis of the tooth. (simple fracture in
enamel and dentine only vs complicated fracture of Cr and root)
worse prognosis of tx as we go coronally towards alv crest. better prognosis if its near apex.
