Monitor for signs and symptoms
Carry out conservative enucleation of cyst

A

Carry out vitality testing

20
Q

Q

Mrs Lim went to the nearest dental clinic when she started experiencing pain and swelling of her right posterior mandibular gums. She developed a fever a day after the swelling and it was noted that her #46 and #47 were mobile and tender to percussion. Upon taking an OPG, and running a histopathology test, she was diagnosed with acute osteomyelitis. Which of the following does NOT correspond with her diagnosis?

When the xray came out, you noted that #25 has a well-circumscribed periapical radiolucency, with a dimension of 2mm by 2mm, surrounded by dense sclerotic bone. There is also widening of the lamina dura. Which of the following is the most likely diagnosis?

Acute apical abscess
Condensing osteitis

Periapical osseous dysplasia

A

Periapical granuloma

29
Q

Which of the following is true?

Osteomyelitis occurs more in the maxilla than the mandible.

30
Q

A 75 year-old man comes into your clinic complaining that he is experiencing a dull aching bone pain in his mandible. Upon clinical examniation, you find that he has some mobile teeth in his mandible, but no exposed bone can be seen. He is a regular dental attendee and does not show signs of chronic periodontal disease. An OPG was taken and lamina dura thickening and decrease in PDL space can be seen. In his medical questionnaire, you notice that he is currently taking Fosamax. Which stage of MRONJ is this patient likely to be at?

Stage 0
Stage 1
