B) Dental lamina cysts
C) Epstein pearls
D) Fordyce granules
D
Which of the following is the correct statement?
A) Bohn nodules are usually found on the crest of the alveolar ridge.
B) Dental lamina cysts are odontogenic in nature and arise from the Cell Rests of Malassez.
C) Epstein pearls form due to the epithelial entrapment between palatal shelves.
D) Radiographs should be taken for eruption cysts to check for pathological calcifications.
C
A one-year old infant presents with multiple palpable soft lesions on the crest of his maxillary alveolar ridge. Which is the most likely diagnosis?
A) Bohn nodules
B) Dental lamina cysts
C) Epstein pearls
D) Eruption cysts
B
Which of the following conditions is seen more commonly in children?
A) Fordyce granules
B) Lateral periodontal cyst
C) Oral melanotic macule
D) Retrocuspid papillae
D
What is a major concern when extracting teeth in a patient with vascular abnormalities?
A) Extraction in a region where intraosseous arteriovenous malformation is present will lead to hemorrhage
B) The area will be swollen and block access to the site of interest
C) The area will appear very red and disrupt your vision
D) The use of LA in patients with vascular abnormalities is strictly contraindicated
A
A parent brings their newborn child to the dentist after noticing some bumps in their baby’s mouth. Upon inspection, you notice that there are cysts on the crest of the alveolar ridge. What kind of cyst does the newborn present with?
A) Bohn nodules
B) Dental lamina cysts
C) Epstein pearls
D) Eruption cysts
B
All the following are true about cleft lip and palate except:
A) Due to failure of palatal shelves to fuse
B) Maternal risk factors include tobacco use, stress and medications
C) May be associated with syndromes such as Van der Woude Syndrome and Treacher Collins Syndrome
D) Treat by surgical repair of lip and palate as soon as possible after birth
D
A patient came into a dental clinic complaining of a certain feeling of “roughness” whenever he ran his tongue over his left buccal mucosa. Upon looking into the site of complaint, the dentist noticed that the mucosal lining has multiple yellowish papules. The dentist panicked as he forgot about all the things he learnt in OMOPOR modules in dental school. As a result, he ordered biopsy to be taken straight away.
Was the biopsy a right call to make?
A) No, biopsy is a very invasive procedure as it involves the gross removal of tissue from the patient’s body. Therefore, a smear, which is less invasive than a biopsy, should have been done instead.
B) No, the dentist should have been able to come up with a definitive diagnosis clinically that the patient presents with a normal anatomical variation and hence, no further investigation is needed.
C) Yes, the dentist made the right call to examine the clinical findings further through biopsy as the histological slides helps with coming up with differential diagnosis
D) Yes, the decision to do a biopsy is apt as it is optimal to rule out malignancy as the etiology of the lesion as soon as possible.
B
An infant is found to have a frenum attachment near the tongue tip, and is diagnosed with ankyloglossia. This has resulted in restricted tongue movement for the infant. Which of the following is the most justified reason as to why the infant should undergo a frenotomy?
A) The abnormal frenulum is impairing the infant’s ability to be breastfed
B) To correct articulation problems
C) To prevent the infant from developing malocclusion in the future
D) To reduce the chances of gingival recession
A
A 3 year old patient presents with bilateral, moderately firm, smooth-surfaced, sessile lumps on the lower lingual gingiva of the mandibular canine. Which is the most likely diagnosis?
A) Bohn nodules
B) Congenital epulis
C) Fordyce granules
D) Retrocuspid papillae
D
