Q

What should be considered around gingival stability in children?

A

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

Q

Effect of puberty in gingivitis in girls?

A

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

Q

Drugs causing gingival enlargement?

A

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

Q

How can width of keratinised gingival effect health?

A

Narrow zone of KG = cause of recession?

Wider zone may be better to withstand inflammation and trauma

Q

How does diabetes effect perio?

A

Diabetes and period both inflammatory condition

upregualtion of cytokines = local damage

17
Q

Treatment of periodontitis in primary dentition?

A

Debridement (amoxicillin)

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

18
Q

Genetic factors contributing to aggressive Perio?

A

Ethnic groups
Family history
Inherited condition with leukocyte defects

19
Q

List 3 systemic disorders with periodontal fetaures

A

Papillon-lefevre syndrome
Neutropenias
Ehlers-Danlos

20
Q

Describe Papillon-lefevre syndrome

A

Affects immune and inflammatory response

Keratosis of plasma and gingiva
