WITH CORRECT ANSWERS UPDATED 2025/26
In this condition, radiographs will show a lack of enamel opacity
and a pathological loss of enamel. The crowns of the teeth look
just like the root as far as density.
Amelogenesis Imperfecta
Amelo = enamel
Genesis = origin, beginning
Imperfecta = not developed perfectly, correctly
Note: crowns look like an extension of the root and there is an
obvious pulp chamber
What is the traditional clinical sign of amelogenesis imperfecta?
Snow-capped enamel (incisal edges are much whiter than the
rest of the tooth.
The teeth also are typically more yellow or brownish in color.
Pitting of teeth
In this condition, radiographs will show bulbous crowns with
short and slender roots; also absent pulp chambers and root
canal.
,Dentinogenesis Imperfecta
Dentino = dentin
Enamel is usually lost early due to loss of scalloping at the DEJ.
Clinically, teeth with dentinogenesis imperfecta may appear
_________ to ________. They may exhibit ____________ or __________
hue.
Gray; yellow brown; translusent; opalescent
True or False: People with dentinogenesis imperfecta are more
susceptible to dental caries than those with normal teeth.
False
Currently thought to represent a chronic fungal (candidiasis)
infection in this area of the tongue.
Median rhomboid glossitis
Median = middle
Gloss = tongue
Itis = inflammation
, In general, no tx is necessary for median rhomboid glossitis.
What medication may be prescribed for a pt with symptoms (pain
or burning sensation)?
Anti-fungal medications to kill the yeast and thereby reduce
symptoms.
What is a mucous cyst that is a painless, thin sac on the inner
surface of the lips called?
Mucocele
Tx: often go away w/out tx but removal may be needed
Fluid is clear, sac appears bluish and translucent
This is a type of mucocele, found unilaterally on the floor of the
mouth.
Ranula
Ranulas are caused by _________________.
Local trauma of ruptured salivary duct
Ulcerative granuloma of the tongue is an oral ulcer of traumatic
origin which can also be known as ____________________,
_________________, and ____________________.
- traumatic granuloma
- traumatic ulcerative granuloma with stromal eosinophilia
(TUGSE)
