Answer 3

1. frontal sinus = in frontal bone, above medial orbits
2. maxillary sinus = in maxilla (above cheek bones) along sides of nasal cavity
3. ethmoid sinus = between orbits

Answer 5

• causes further tooth loss
• muscle imbalance from mandible + maxilla out of alignment - produces muscle spasm, tenderness + chronic headaches

2. Epstein pearls = normal newborn/infants = small, whitish, glistening, pearly papule along median raphe of hard palate + on gums where they look like teeth, they’re small retention cysts + disappear within first couple weeks
3. bednar apthae = traumatic areas / ulcers on posterior. hard palate on either side of midline, result from abrasions while suckling

Question 13

compare appearance of nasal turbinates + nasal polyps

Answer 13

nasal turbinates = quite vascular + tender if touched
nasal polyps = smooth, pale grey, avascular, mobile, non tender

Question 14

describe the appearance of ankyloglossia

Answer 14

short lingual frenulum, fixing tongue tip to floor of mouth + gums

Question 15

deep furrows divide papillae into small irregular rows, occurs in Down syndrome

Question 16

describe the appearance of geographical tongue

Answer 16

patterns of normal coating interspersed with bright with bright red, shiny, circular bald areas caused by atrophy of filiform papillary, with raised pearly boarders

describe the appearance of black hairy tongue

Answer 17

not hairy but elongation of filiform papillae + painless overgrowth of mycelial threads of fungus, infection of tongue, occurs after use of antibiotics or smoking
