A molar with buccal swelling close to the gingival margin with isolated deep periodontal pocket depth, but responsive to pulp sensibility test may indicate
cracked tooth
apical periodontitis
chronic apical abscess
acute apical abscess
K-files are used to
locate roof of pulp chamber
confirm internal root resorption
obturate the root canal
measure size of apical foramen
Pain on all maxillary posterior teeth on the left quadrant, on touching and biting. It can be exacerbated by bending down. All teeth at the quadrant appeared sound, with mild gingival inflammation, and tender on percussion and palpation. Pulp sensibility test was unremarkable. Differential diagnosis for this condition is
Maxillary sinusitis
Atypical facial pain
Trigeminal neuralgia
Perio-endo lesion
Orthodontic extrusion can aid in
creating space for long-term edentulism
restoring supra-gingival cavities
atraumatic extraction for intentional replantation
repositioning extrusive dental injury
Persistence of endodontic infection after vigorous disinfection using strict aseptic technique can be due to
primary intra-radicular infection
secondary intra-radicular infection
dependent extra-radicular infection
independent extra-radicular infection
An anterior tooth with large periapical radiolucency was root canal treated. At 1 year review, the tooth was asymptomatic, however the tooth was discolored, no reduction in periapical lesion size, and persistent apical abscess. Determine the most conservative treatment plan.
Extraction
Non-surgical root canal re-treatment
Surgical root canal re-treatment
Intentional replantation
The suitable treatment for a mechanical exposure of pulp with clean periphery is
indirect pulp capping
direct pulp capping
full pulpotomy
root canal treatment
Sclerotic dentine causes
apical periodontitis
pulp canal obliteration
internal root resorption
intra-radicular endodontic infection
Mechanism for pulpal protection against microbial invasion is
activation of odontoclast cells
regeneration of odontoblast cells
deposition of sclerotic dentine
deposition of primary dentine
Non-invasive test to determine pulp vitality includes
cavity test
thermal test
laser doppler flowmetry
electric pulp test
Based on the concept of ALARA, which radiological technique is suitable to determine the presence of radix entomolaris on a mandibular molar?
small field of view CBCT
large field of view CBCT
panoramic radiograph
SLOB technique
What is the differential diagnosis for the periapical radiolucency?
Fibro-osseous dysplasia
Osteosclerosis
Nasopalatine canal
Nasolabial cyst
Best material of direct pulp capping is
hydraulic cement
glass ionomer cement
zinc oxide eugenol
calcium hydroxide
Supernumerary root located lingual to the distal root of mandibular molar is called
radix paramolaris
radix entomolaris
talons cusp
dens evaginatus
Which anatomical variation is most likely causing the periapical radiolucency seen on tooth 35?
Dens invaginatus
leongs premolar
talons cusp
cusp of carabelli
Describe the root apex of tooth 35
(a)
What can be the suitable treatment for tooth 35?
Revascularization
Extraction
Intentional replantation
Apexogenesis
Regarding tooth 34. What is the likely number of roots?
1
2

4
How many root canals are most commonly present in mandibular premolars?
1
2
3
4
OIIRR is considered as
Transient external root resorption
an indication for root canal treatment
an infectious lesion
a developmental anomaly
