Periodontology

Question 1

periodontal health

Answer 1

free from inflammatory periodontal disease, that allows an individual to function normally, avoids physical or mental consequences due to current or past disease

Question 2

plaque biofilm induced gingivitis

Answer 2

supragingival plaque accumulation, inflammatory cell infiltrate in connective tissue
disrupted junctional epithelium
apical migration of plaque and increase in gingival sulcus depth [false pocket]

no periodontal attachment loss, mot apical is CEJ

Question 3

causes of non-biofilm induced gingivitis

Answer 3

genetic/developmental disorders
specific infections
inflammatory and immune conditions and lesions
reactive processes
neoplasms
endocrine
nutritional and metabolic diseases
traumatic lesions
gingival pigmentation

Question 4

predisposing local factors for necrotising gingivitis

Answer 4

malocclusion [instanding, rotated]
traumatic injury [intrusion, luxation, avulsion]
biofilm retentive factors
incompetent lip seal

Question 5

modifying systemic factors for necrotising gingivitis

Answer 5

HIV positive
cyclosporin
vit c deficiency
leukaemia
pregancy

Question 6

features of necrotising gingivitis

Answer 6

pain, necrosis of interdental papillae
‘punched out’ appearance
ulceration, spontaneous bleeding
lymphadenopathy, fever

can progress to necro perio

Question 7

causes and tx of gingival overgrowth

Answer 7

genetics, calcium channel blockers, puberty

home care, PMPR frequent appointments

Question 8

4 main features of periodontitis

Answer 8

apical migration of junctional epithelium beyond CEJ
loss of attachment
junctional epithelium to pocket epithelium
alveolar bone loss

Question 9

3 pathogens in periodontitis

Answer 9

p.gingivalis
p.intermedia
t.forsythia

Question 10

what is the early clinical signs of perio in teens

Answer 10

> 1mm loss of attachment of cementum to PDL

Question 11

molar incisor vs generalised pattern of perio

Answer 11

molar incisor - only
generalised - 3 teeth other than those

Question 12

necrotising periodontitis signs

Answer 12

extension of NG
necrosis/ulceration of interdental papilla
bleeding of gingival tissues
PDL loss and rapid bone loss
pseudomembrane formation
lymphadenopathy
fever

Question 13

systematic disease/issues contributing to perio

Answer 13

down syndrome
PLS
LCH

Question 14

necrotising stomatitis

Answer 14

extends beyond gingiva to soft tissues leading to bone denuadation
false pockets

Question 15

paeds BPE

Answer 15

7-18 age
only 6 teeth
WHO 621 probe

16, 11, 26, 36, 31, 46

Question 16

plaque score values

Answer 16

around gingival margin

10/10 - clean
8/10 - line of plaque cervical
6/10 - cervical third of crown
4/10 - middle third of crown
