Q

why were the acute periodontal conditions in 1999 classification replaced

A
  • cant distinguish between gingival and periodontal abscess easily
  • abscess is by definition an ACUTE LESION thus chronic/ acute terms removed
  • peri-coronal= when 3rd molars are trying to erupt but theres no space, we get formation of peri-coronal abscess. but this does not relate to periodontium tissues thus removed

OR
previous NPD: residual craters (lead to generalised NG, possible NP progression)
OR
local factors: root proximity, tooth malposition(will lead to LOCALISED NG –> NP progression)

Q

periodontal abscess can be further classified based on the SOURCE of infection. this includes..

A
  1. pulp necorsis (due to pulp tissues dying mostly bc of caries OR during crown prep an instrument that compromises the blood supply)
  2. periodontal infections
  3. peri-coronitis (3rd molar struggling to come out becomes infected)
  4. trauma or surgery
  5. microbes (mainly gram -ve anaerobes)

Q

what are the hypothesised periodontal abscess aetiological factors

A
  1. diabetes= increases the susceptibility to abscess formation if not managed
  2. systemic antibiotic therapy= can target ‘good bacteria; and lead to a superinfection with opportunistic org. here, you would prescribe antibiotics.
  3. furcation involvement= when theres an abscess between furcation it can be difficult to clean/ instrument
  4. occlusion of pocket orifice= can be due to many things:
    - no clearance of bacteria
    - accumulation of host cells
    - some host cells will be damaged by neutrophils released lysosomal enzymes
    - healing post scaling

17
Q

when would occlusion of pocket orifice occur

A

when there is incomplete removal of calculus
impaction of food/ foreign body
bacterial invasion after instrumentation

18
Q

what are the clinical features of periodontal abscess

A
  1. vital pulp response
  2. affected tooth will have deep pockets and CAL
  3. mobile tooth
  4. may be PAINFUL to bite on
  5. tooth extrusion (high height) thus patient may have sensation to grind on it
  6. ovoid elevation of gingiva on lateral apsect of ROOT
  7. gingiva are red, swollen, smooth, shiny
  8. suppuration from pocket
19
Q

there are 2 different stages of developmental abscess what are they

A

early stage, acute= pus not yet draining (there will be swelling, redness etc)

if pus is draining, may become chronic

20
Q

can periodontal abscess be seen on radiograph

A

NO

but, if its a perio related patient, then may seen bone loss/ furcation involvement if MOLAR

21
Q

how do you distinguish from pulpal pain and pain from acute perio abscess

A

acute presentation of perio abscess= THROBBING pain

pulpal pain= SHARP pain

(this diagnosis will be based on clinical exam, pulp vitality test, radiograph)

22
Q

what is the management of a perio abscess, PUS NOT draining

A

may be emergency so control infection, relief pain, assess prognosis

  1. check that there is no impacted material in pocket
  2. relieve occlusion e.g. affected tooth may be slightly extruded, may have to grind down opposing tooth?
  3. advise hot salt mouthwash to increase drainage
  4. advice painkillers (ibuprofen, paracetamol)
    BUT IF severe pain, cant achieve drainage, AND risk of spread of infection then….
  5. prescribe systemic antibiotics (penicillin, metrandiazole)
  6. review patient after a few days
23
Q

what is the management of a perio abscess, WITH PUS to drain

A
  1. achieve drainage first - local gentle debridement in pocket, remove impacted material, incision and drinage if indicated
  2. advise hot salt moutwashes
  3. relieve occlusion
  4. advise pain killers
  5. review in few days
24
Q

indicators of perio abscess with SYSTEMIC INVOLVEMENT

A 
EXTRA oral swelling
lymphadenopathy
rarely cellulitis 
malaise
increased temperature
25
Q

what is the management of a perio abscess, with SYSTEMIC INVOLVEMENT

A 
same as pus to drain
AND systemic antibiotics:
- metranidazole
-penicllin
- very powerful combination of met. and amoxycillin for 1 week

then review

26
Q

what is diffrential diagnosis

A

this is the other POSSIBLE DIAGNOSES from information in history, exams, signs, symptoms, special tests

27
Q

in periodontal abscess, diffrential diagnosis may include…

A

periodontic-endodontic lesion
peri-apical abscess

it would NOT include gingival abscess or peri-CORNOAL absesses because dont exist in 2018 classification (will still cover all 4)

28
Q

features of gingival abscess

A

localised purulent infection that involves marginal/ interdental papilla

localised

painful

rapidly expanding

red, shiny, smooth

flucant within 24-48hrs

points and discharges spontaneously

linked with acute inflammatory response to foreign agents

29
Q

features of peri-coronal abscess

A

localised purulent infection WITHIN TISSUE surrounding crown of PARTIALLY erupted toooth
- mandibular 3rd molar is a common site

red, swollen gingival flap

infection may spread

possible systemic involvement

30
Q

aetiology of periodontal-endodontic lesions

A

this lesion would be called ‘combined periodontal-endodontic’ lesion

aetiology may be

  1. primary periodontic, secondary endodontic (a necrotic pulp as a result of periodontal involvement) has a poor hopeless prognosis
  2. primary endodontic, secondary periodontic (periodontium is involved after pulpal necoris)
31
Q

features of peri-apical abscess

A

pulpal necrosis (carious pulpal involvement on heavily restored tooth)

non-vital (confirm with pulp vitality test)

peri-apical tissues involved

periodontal tissues involvement is not a key feature

tooth tender to percussion (TTP) thus may be acutely painful

32
Q

why are NG and NP collectively called NPDs (a type of acute perio abscess)

A

because they may be different stages of the SAME infection

NB. there is NO such thing as chronic NPDS, but they may ‘recur’

33
Q

features of NPDS

A 
RAPID onset
PAINFUL!!!
inter-dental necrosis 
bleeding gingivae
necrotic ulcers affecting interdental papillae
punched out papillae
ulcers= painful, covered by grey slough
gingival bleeding with little provocation 
possible hallitosis 
possible lymph nodes involvement
tend to occur in young adults in 20s
34
Q

what is the aetiology of NPDS

A
  1. fusiform- spirochaete bacterial infection
    (selenomas spp, fusobacterium spp, p. intermedia, and spiroachaetes such as trepenoma sp)
  2. 4 zones of gingival lesion: bacterial zone, necrotic zone, neutrophile rich zone, spircochaetal infection zone
  3. in young adults due to stress, immunosuppression, smoking, poor diet/ malnutrition, pre-existing gingivitis, poor OH, previous history of NPDs
35
Q

what is the management of NPDS: local and systemic

A 
local measures= remove gross deposit/ calculus (ultrasonic scaler)
oxidising mouthwash (hydrogen peroxide)
gentle alcohol +chlorohexidine rinse to preven a secondary infection

systemic measures= metrandizole 200/250 mg for 3 days

after this ‘acute’ phase would consider perio therapy including:OHI, smoking cessation, scale/ polish/ RSD, and focusing on other predisposing factors like stress

36
Q

NPDS can become recurrent as NP and N. stomatitis. what is the difference between them

A

NP= necrosis of gingival tissues, periodontal ligament, alveolar bone

NS= necrotising process BELOW/ APICAL to the mucogingival junction

37
Q

what causes herpetic gingivo stomatitis and how

A

caused by herpes simplex type ONE

  • primary contact- is TRANMISSIBLE via saliva
  • it is a disease of childhood, becoming more common in older ages. immunity to virus develops
  • decreased resistance may lead to herpes LABIALIS= cold sore- in 30% of population. this IS transmissble
  • defining feature = VESICLES
38
Q

what is herpetic WHITLOW

A

when HG transmitted to dentist from infected patient

39
Q

features of primary herpetic gingivo stomatitis

A 
acute onset
fever
malaise
cervical lymphadenopathy
gingivae acutely inflammed- VERY red, swollen 
rising titre of ig to virus
vesicles
40
Q

what are the features of vesicles of primary HGS

A

found on ANY PART OF MUCOSA- often found on hard palate, dorsum of tongue, gingiva
PAINFUL
2-3 mm
dome shaped
rupture= leaves circular shallow ulcer with yellow/ grey floor and red margin
smears show ballooning degeneration of viral damaged cells

41
Q

what is management of primary HGS

A

let it run its course for 7-18 days
NO antibiotics because virus
ACYCLOVIR=anti viral therapy, but needs to be used early to be effective
soft diet, lots of fluid
ANALGESICS= for pain/ fever
bed rest?
chlorohexidine/ gentle swab of it to relieve soreness, control secondary infection, increase healing possibly
