intro to management of PDD

Question 1

classifications of PDD

Answer 1

periodontal health, gingival diseases and condiditons
periodontitis
other conditions
peri implant diseases

Question 2

periodontisi

Answer 2

4 stages ie initial, moderate

3 grades ie slow rate, fast rate

Question 3

clinical features and characteristics of PDD

Answer 3

red colour
stippling has gone
increased volume of gingivae
bleeding on probing
periodontal pocket formation
bone loss
furcation exposure
drifitng and exfoliation of teeth

Question 4

basic periodontal examination

Answer 4

dentition divied into 6 sextants ie 3 in each denttion

highest score in each sextant is recordeed

Question 5

what would you do for sextants with code 3

Answer 5

need to do full charting after treament initilly

Question 6

what would you do if code 4 is present in any sextant

Answer 6

detailed periodontal charting for entire dentition

6 point charting measuring the pocket depth around the tooth

Question 7

furcation defects classifications

Answer 7

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

Question 8

tooth mobility scoring

Answer 8

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

Question 9

local risk factors for perdiodontits - plaque and plaque retentive factors

Answer 9

calculus
restorations with poor marigns/comtour
mispositioned teeth
tooth surface defects

Question 10

systemic risk factors for the disease

Answer 10

smoking tabacco
diabetes
genetics
osteoporosis
psychosocial factros

Question 11

what gene increases suceptibilty to gaining PDD

Answer 11

IL1

Question 12

diabtetes and PDD

Answer 12

bad bacteria increase in those with diabetes

neurophils are impaired, will go towards sugar rather than fighting with imune system as they like sugar

Question 13

main species that cause periodontitis

Answer 13

aggregatibater
p.gingivalis
tannerella forsythia

Question 14

why type of bacteria are the main species that cause periodontitis

Answer 14

gram -

Question 15

oral bacteria healty vs periodontitis

Answer 15

composition of subgingival plaque is similar to supra gingival in healthy
different in periodontitis

Question 16

periodontal treatement phases

Answer 16

systemic phase
initial hygine phase
non surgical therapy 
corrective phase (if health has improved)
maintenase

Question 17

systemic phase of treaement

Answer 17

eliminate or decrease the influences of systemic risk factors to protect the patient and dental care provider against infectious hazard

Question 18

inital hygiene phase of treament

Answer 18

mechanical supragingival plaque control (brushing)

chemical supra gingival plaque control (mouthwash)

Question 19

non surgical therapy phase

Answer 19

scaling and root surface debridement

leave for 3mn and then reassess

Question 20

corrective phase of treatment

Answer 20

periodontal surgyer
endodontic therapy
restorative and prosthetic treatment

Question 21

aim of initial hygiene phase

Answer 21

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

Question 22

what tooth brushing technique for patients with deep periodontal pockets and subgingival cleaning

Answer 22

modified bass technique

Question 23

interdentla cleaning

Answer 23

dental floss can be used in areas of tight contact

interdental brushes for larger spaces

Question 24

chlorahexidine

Answer 24

plaque inhibition and prevention of gingivitis

Question 25

rot surface debridement

Answer 25

decreases the total number of subgingival bacteia and shift in the relative proportion of different microbial species and reduction of periodontal pathogens

Question 26

hand instruments adv and dis

Answer 26

good tacile sensation 
minimise aerosol production
dis
tim consuming
technique sensitive
can lead to excessive surface tooth tissue removal

Question 27

what is used for supra and sub gingival scaling

Answer 27

supra
sickle and hoe
sub
curette

Question 28

types of ultrasonic instruments

Answer 28

magnetostrictive

piezoeletric

Question 29

magnetostrictive ultrasonic instruments

Answer 29

magnetic field causes expansion and contraction of the insert

Question 30

piezoelectric

Answer 30

dimensional changes in had piece

Question 31

complications of treatment

Answer 31

dentine sensitivity

gingival recession

Question 32

what causes dentine sentisit

Answer 32

pockets are eliminated
gums will shrink back and reveal more tooth
dentine can be exposed causing sensitivity

Question 33

what casues gingival recession from treaement

Answer 33

black triangles where interdental papilla was

Question 34

limitations of close root surface debridment

Answer 34

may not stop progressive and agressive disease completely
deep complex bone treemetns
sever hyperplasia/tissue deformity
persistant acute episodes

Question 35

aims for periodontal surgery

Answer 35

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
