Perio Flashcards
why may RSD not successful in eliminating pocket bacteria
difficult access - especially furcation
patient not adhering to OHI requirements
lack of operator experience
immunocompromised patient
how do you manage a patient with periodontal abscess and systemic involvement
drainage and incision
gentle subgingival PMPR
hot saline m/w
metronidazole
what bacteria are involved in necrotising gingivitis
p. intermedia
fusobacterium
clinical signs and symptoms of necrotising gingivitis
halitosis, punched out papilla, grey sloughing, crater like ulcers
5 risk factors of necrotising gingivitis
stress, immunocompromised, smoking, lack of sleep, poor oral hygiene
how is necrotising gingivitis managed
ultrasonic debridement
chlorhexidine mouthwash
antibiotics if systemic involvement (metronidazole 400mg, TID for 3 days)
what information is given to a patient going under periodontal surgery to achieve consent
gingival recession
infection
reduction in pocket depth
other tx options - repeat PMPR
increase in pocket depth and mobility if no treatment
what is SIRS
temperature less than 36 or more than 38
decreased respiratory rate
WBC less than 4000 cells/ mm cued
heart rate more than 90bpm
hat is the 2017 classification of periodontal disease
health
plaque induced gingivitis
non-plaque induced gingivitis
periodontal disease
necrotising periodontal conditions
perio-endo lesions
mugogingival lesions
periodontitis as manifestation of systemic disease
systemic disease affecting periodontal tissues periodontal abscess
what is the radius of destruction of plaque
around 2mm
what is chlorhexidine
bisbiguanide antiseptic
how does chlorhexidine work
1 cation adheres to pellucle and 1 cation disrupts bacterial membrane
antibacterial and antiseptic
works against gram positive and negative bacteria
what is the substantivity of chlorhexidine
12 hours
give 2 doses for chlorhexidine
10ml twice daily
15ml twice daily
8 uses of chlorhexidine
surgical pre-op rinse
post intra oral surgery
OHI for patients with jaw fixation
necrotising gingivitis
recurrent oral ulceration
denture stomatitis
dry socket treatment
endo irrigant
local factors for gingival recession
periodontal disease
habits
traumatic tooth brushing
high frenal attachment
crowding
traumatic incisor relationship
how may vertical bone defects be classified
by number of walls affected
1, 2 or 3
2 or 3 walled involvments heal better
why is diabetes a risk factor for perio
poor wound healing
pro inflammatory disease
impaired neutrophil function
advanced glycation end products cause increased tissue destruction
what are two tests for diabetes
fasting plasma glucose
random plasma glucose
what is the test for diabetic control evaluation
HbA1c
how does smoking affect periodontal tissues
impaired chemotaxis and phagocytosis
affects cytokine production
affects enzymes
blood flow restricted
what is the diagnosis for inflamed gingivae extending beyond mucogingival junction
desquamative gingivitis
what 3 oral conditions are associated with desquamative gingivitis
lichen planus
pemphigoid
pemphigus
what are topical treatments for desquamative gingivitis
betamethasone
beclomethasone
tacrolimus mouthwash
