Gingival Recession Flashcards
(64 cards)
What is gingival recession?
Migration of gingival margin apical to CEJ (cement-enamel junction)
Is recession indicator active disease?
No
Can indicate past active or active disease
Why is recession part of informed consent?
Recession is risk of healing and periodontal therapy
How can recession present?
Generalised or localised
When may see general recession?
Toothbrush trauma
Periodontal disease
When may see localised recession?
Localised labial defects
Localised pockets
Aetiology of recession?
Predisposing and precipitating factors?
Predisposing factors of recession?
Thin periodontal phenotype
Tooth position
Previous ortho tx - too far labail
Position muscle attachment
What are precipitating factors of recession?
Gingival inflamamtion Toothbrush trauma Iatrogenic trauma Self-inflicted trauma Deep OB
Stages of gingival recession?
Stage 1 = normal tissue w/ subclinical inflammation
Stage 2 = clinical inflammation
Stage 3 = increased epithelium proliferation, loss CT core
Stage 4 = merging epithelium = separation and recession gingival tissue
What is gingival phenotype?
Gingival thickness and keratinised tissue width
What keratinised tissue width?
Dimension from mucogingival junction to gingival margin
What is an adequate keratinised tissue width?
3mm
Is keratinised tissue width consistent in mouth?
No
What may be indication of thin gingival pheotype?
See periodontal probe - less 1mm thickness
How does sub gingival plaque interact with tissue?
Lateral/apical extension inflammatory cells
How does sub-gingival plaque affect thin and thick tissue?
In thick gingival tissue infiltrate only occupy small amount CT
In thin gingival tissue entirity CT can be affected by inflammatory infiltrate = degradation tissue = recession
Where more common to see recession in healing of periodontitis?
In areas of bone loss
Different traumatic elements that can be precipitating factor?
Mechanical - toothbrushing
Physical - piercings, poorly designed dentures
Chemical - drygs/ tobacco
What pattern recession expect to see in toothbrush recession?
Even distribution - buccal surface
Side opposite to dominant hand
Where might see recession associated w/ ill-fitting dentures?
Around abutment teeth
How can smoking contribute to recession?
Reduced gingival blood flow = reduced immune response
Altered cellular response
How can tooth position affect recession?
Position and orientation of tooth can influence thickness overlying gingival tissue
What teeth are most prone to recession?
Mandibular incsiors
