16
Q

clinical features of acute periapical abscess?

A

pain
swelling/ sinus

17
Q

histopathology of acute periapical abscess?

A

central collection of pus with an adjacent zone of preserved neutrophils
surrounded by granulation tissue

18
Q

treated options for acute periapical abscess?

A

drainage and XLA/ endo

19
Q

clinical features of chronic periradicular periodontitis?

A

non-vital tooth, may be previous RCT
often minimal symptoms
apical radiolucent lesion may be evident on radiograph

20
Q

histopathology of chronic periradicular periodontitis?

A

chronic inflammatory changes

lymphocytes and plasma cells
granulation tissue progresses to fibrosis

resorption of bone

21
Q

treated options for chronic periradicular periodontitis?

A

XLA
endo
endo retreatment
periradicular surgery

22
Q

what is a periapical granuloma?

A

mass of inflamed granulation tissue at the apex of a non-vital tooth

not a true granuloma

23
Q

what can a periapical granuloma progress to?

A

an abscess
may undergo cystic change (radicular cyst)

24
Q

clinical features of periapical granuloma?

A

as for chronic periradicular periodontitis - minimal
however
apical radiolucent lesion typically evident on radiograph

25
Q

histopathology of periapical granuloma?

A

inflamed granulation tissue
proliferation of cell rests of Malassez
haemosiderin and cholesterol deposits from RBC/inflam cell breakdown
resorption of adjacent bone and or tooth

26
Q

treatment options for periapical granuloma?

A

XLA
endo
endo retreatment
periradicular surgery

27
Q

histopathology of pericoronitis?

A

acute and chronic inflammatory changes including oedema, inflammatory cells, vascular dilation, fibrotic connective tissue

28
Q

what type of cyst may arise in chronic pericoronitis?

A

paradental cyst

29
Q

clinical features of pericoronitis?

A

pain
swelling/ tenderness of operculum
bad taste
trismus

30
Q

treatment for pericoronitis?

A

irrigation
consider XLA of opposing tooth
antibiotics (if systemically unwell)
