Answer 2

associted with partially erupted teeth

Question 3

Periodontal Abscess

Answer 3

localised acute exacerbation of a deep pre-exisitng pocket

rapid destruction of perio tissues with a negative effect on progonsis of affected tooth

Question 4

Signs and symptoms of periodontal abscess

Answer 4

swelling
bleeding
deep perio pocket
suppration 
fever
enlarged regional lymph nodes
TTP in lateral direction
vital and pre existing perio disease
tooth mobility
more llikley to have generalised horizontal bone loss

Question 5

Treatment for periodontal abscess

Answer 5

sub ging instrumentation short of base of the perio pocket to avoid damage
drain pus by incision or through perio pocket
recommend 0.2% CHX mw until acute symptoms subside
Do not prescribe antibiotics unless signs of spreading infection
- amoxicillin 500mg
XLA of tteh with poor prognonsis

Question 6

Endo lesion with perio involvment

Answer 6

pathological communication between the endo and perio tissues of a tooth

Question 7

Signs and symptoms of endo lesion with perio

Answer 7

deep perio pocket reaching or close to apex
tooth mobility and sinus tract
crown and ging colour alterations
pain on palpation and perucussion
bone resorption in the apical or furcation region
crown and ging colour alteration
negative or altered repsonse to pulp vitality tests

Question 8

Treatment for endo lesio with perio

Answer 8

Carry out RCT
observe
RSD after 3 months
recommend analgesia
CHX mw
Do not prescribe antibiotics unless sign of spreading infection or systemic involvement
review within 10 days and carry out supra and sub ging scaling

Question 9

Perio lesion with endo involvement

Answer 9

the apical progression of a perio pocket mat continue until the apical tissues are invloved meaning the pulp can become necrotic as a result of infection entering via lateral canals or the apical foramen

Question 10

True combined endo and perio lesion

Answer 10

when an endo lesion progresses coronally and joins with an infected perio pocket progressing apically
tooth will be non vital and perio will be detected in other areas with periapacal and bone loss
clincial attachement loss and a tooth with a necrotic pulp

Answer 11

LPS
Toxins
peptigylcans
porteases

Question 12
