1

How does periodontium differ in children?

Marginal gingival tissue sore vascular
Fewer connective tissue fibres
Thinner epithelia
Less keratinisation
Redder - often mistaken for inflammation

2

How can tooth eruption effect periodontium?

Localised hyperaemia (Increased blood flow) = persistent swollen papillae
Eruption of permanent teeth accompanies migration of JE

3

What should be considered around gingival stability in children?

Gingival margin and JE continue to shift after eruption - mistaken for gingival recession
at 12 years - 1,2,3,5,6 stable
at 16 - should be stable

4

Effect of alveolar bone being more vascular and fewer trabecular?

Enhanced rate of progression of Periodontal disease in primary dentition

5

Effect of puberty in gingivitis in girls?

Oestrogen - increases cellularity of tissues
Progesterone - increase permeability of gingival vasculature
Oestradiol - supports growth of BP microbes

6

Drugs causing gingival enlargement?

Anti convulsants e.g. phenytoin (epilepsy)
Immunosuppressant - ciclosporin (prevent organ transplantation)
Calcium channel blocker - Nifedipine (post-transplant to reduce nephrotoxicity in ciclosporin)

7

How does phenytoin cause gingival enlargement?

Overproduction of collagen

8

How does ciclosporin cause gingival enlargement?

Unknown - stimulation of fibroblasts, increased collagen production

9

Management of gingival enlargement?

OH, debridement
Gingevectomy
Change medication

10

How can width of keratinised gingival effect health?

Narrow zone of KG = cause of recession?
Wider zone may be better to withstand inflammation and trauma

11

How can gingival recession effect tooth position?

In permanent incisors - may be displaced labially

12

When is modified BPE used?

Children under 18 years

13

What is modified BPE?

Uses 6's and 1's only

14

Local risks factors for Perio?

Malocclusion, trauma
plaque retentive factors

15

General risk factors for Perio?

Inherited condition - Ehlers danlos, papillon-lefevre syndrome
Diabetes
Smoking

16

How does diabetes effect perio?

Diabetes and period both inflammatory condition
upregualtion of cytokines = local damage

17

Treatment of periodontitis in primary dentition?

Debridement (amoxicillin)
If general rather than local may extract primary dentition to remove aggressive pathogens before secondary teeth erupt

18

Genetic factors contributing to aggressive Perio?

Ethnic groups
Family history
Inherited condition with leukocyte defects

19

List 3 systemic disorders with periodontal fetaures

Papillon-lefevre syndrome
Neutropenias
Ehlers-Danlos

20

Describe Papillon-lefevre syndrome

Affects immune and inflammatory response
Keratosis of plasma and gingiva
