intro to management of PDD Flashcards
classifications of PDD
periodontal health, gingival diseases and condiditons
periodontitis
other conditions
peri implant diseases
periodontisi
4 stages ie initial, moderate
3 grades ie slow rate, fast rate
clinical features and characteristics of PDD
red colour stippling has gone increased volume of gingivae bleeding on probing periodontal pocket formation bone loss furcation exposure drifitng and exfoliation of teeth
basic periodontal examination
dentition divied into 6 sextants ie 3 in each denttion
highest score in each sextant is recordeed
what would you do for sextants with code 3
need to do full charting after treament initilly
what would you do if code 4 is present in any sextant
detailed periodontal charting for entire dentition
6 point charting measuring the pocket depth around the tooth
furcation defects classifications
degree I
horizontal bone loss less than one third the width of tooth
degree II
horiontal bone loss more than one third of the width of tooth but less than the total width
degreeIII
through and through furcation bone loss
through one furcation meet the next
tooth mobility scoring
degree 0 physiological mobily 0.1 to 02mm normal degree 1 1mm horizontal mobility degree 2 greater than 1mm horizontal mobility degree 3 severe mobility greater than 2mm in horizontal direction or vertical mobility
local risk factors for perdiodontits - plaque and plaque retentive factors
calculus
restorations with poor marigns/comtour
mispositioned teeth
tooth surface defects
systemic risk factors for the disease
smoking tabacco diabetes genetics osteoporosis psychosocial factros
what gene increases suceptibilty to gaining PDD
IL1
diabtetes and PDD
bad bacteria increase in those with diabetes
neurophils are impaired, will go towards sugar rather than fighting with imune system as they like sugar
main species that cause periodontitis
aggregatibater
p.gingivalis
tannerella forsythia
why type of bacteria are the main species that cause periodontitis
gram -
oral bacteria healty vs periodontitis
composition of subgingival plaque is similar to supra gingival in healthy
different in periodontitis
periodontal treatement phases
systemic phase initial hygine phase non surgical therapy corrective phase (if health has improved) maintenase
systemic phase of treaement
eliminate or decrease the influences of systemic risk factors to protect the patient and dental care provider against infectious hazard
inital hygiene phase of treament
mechanical supragingival plaque control (brushing)
chemical supra gingival plaque control (mouthwash)
non surgical therapy phase
scaling and root surface debridement
leave for 3mn and then reassess
corrective phase of treatment
periodontal surgyer
endodontic therapy
restorative and prosthetic treatment
aim of initial hygiene phase
to eliminate the infection in the oral cavity by complete removal of all soft and hard tissue deposits on the root surfaces including the plaque retentive factors
what tooth brushing technique for patients with deep periodontal pockets and subgingival cleaning
modified bass technique
interdentla cleaning
dental floss can be used in areas of tight contact
interdental brushes for larger spaces
chlorahexidine
plaque inhibition and prevention of gingivitis
rot surface debridement
decreases the total number of subgingival bacteia and shift in the relative proportion of different microbial species and reduction of periodontal pathogens
hand instruments adv and dis
good tacile sensation minimise aerosol production dis tim consuming technique sensitive can lead to excessive surface tooth tissue removal
what is used for supra and sub gingival scaling
supra
sickle and hoe
sub
curette
types of ultrasonic instruments
magnetostrictive
piezoeletric
magnetostrictive ultrasonic instruments
magnetic field causes expansion and contraction of the insert
piezoelectric
dimensional changes in had piece
complications of treatment
dentine sensitivity
gingival recession
what causes dentine sentisit
pockets are eliminated
gums will shrink back and reveal more tooth
dentine can be exposed causing sensitivity
what casues gingival recession from treaement
black triangles where interdental papilla was
limitations of close root surface debridment
may not stop progressive and agressive disease completely
deep complex bone treemetns
sever hyperplasia/tissue deformity
persistant acute episodes
aims for periodontal surgery
improvement in tissue control reduction in pocket depth removal of chronically inflamed tissue removal of hyperplastic gingival tissue gain access to root surface for effective debridment
