11) A two year old French bulldog presents with unilateral swelling just behind the right mandibular canine. 405 appears to be absent What is the most likely differential diagnosis?
a) Dentigerous cyst
b) Ameloblastic fibro-odontoma
c) Condensing osteitis
d) Eruption cyst
A. develops due to unerupted teeth. happens to over 70% of unerupted teeth
mandibular 1st premolar most common unerupted tooth in brachys
12) True or false? Odontogenic tumours are common in dogs and cats?
a)true
b) False
B
13) Which is the most common odontogenic tumour of dogs?
a) peripheral odontogenic fibroma
b) odontoma
c) acanthomatous ameloblastoma
d) amyloid-producing odontogenic tumour
C and peripheral odontogenic fibroma. old name- epulides
slow growing benign AA can be locally aggressive
in cats- peripheral odontogenic fibroma most common
others with low prevalence: feline inductive odontogenic tumour
cementoblastoma, odontoma
14) Which projection is best for imaging feline maxillary premolar and molar roots to avoid superimposition of the zygomatic arch?
a) intraoral bisecting angle technique
b) near perpendicular extraoral technique
c) near parallel extraoral technique
d) intraoral near parallel technique
C
in which species can chronic periodontitis lead to alveolar bone expansion and alveolar osteitis as well as bone loss?
cats. characterised by thickening of the buccal alveolar bone along areas of severe periodontitis. maxillary canine teeth seem most affected. the bone can look mottled with prominent trabeculae. can extend beyond the alveolar bone margin and therefore look like osteomyelitis or neoplasia
the pulp cavity is important for?
a) dentin production by odontoblasts
b) enamal production by odontoblasts
c) dentin production by odontoclasts
d) cementum production by odontoclasts
A
radiographically, what other differentials should be given when there is a well defined round periapical radiolucent region
radicular/ periapical cyst
periapical abscess
had to tell apart in early stages.
the most common oral malignant tumour in dogs:
a) SCC
b) melanoma
c) acanthomatous ameloblastoma
d) lymphoma
e) fibrosarcoma
B. followed by SCC and fibrosarcoma
SCC in cats
whats your diagnosis?
compound odontoma with denticles- disorganised small teeth
what is dens in dente or dens invaginatus?
Dens invaginatus is a developmental malformation, in which there is an infolding of enamel into dentine. These infolds represent stagnation sites for bacteria and can predispose to dental caries.
what is tooth root dilaceration?
Dilaceration is a developmental disturbance in shape of teeth. It refers to an angulation, or a sharp bend or curve, in the root or crown of a formed tooth.
which is the most common odontic tumour in cats?
a) odontoma
b) peripheral odontogenic fibroma
c) feline inductive odontogenic tumour
d) cementoblastoma
B
what causes the chevron sign on dental radiographs?
non- pathologic periapical lucent region
