Gingival Recession Flashcards
Anatomy and predisposing factors?
Anatomy
- bone
- malocclusion
- tooth position
- gingival biotype
- attachment
- quality of attached gingiva
- aberrant fraenal
Name the general factors contributing to recession?
Mechanicall forces
Anatomy
Iatrogenic damage
Pathological factors
Ageing
iatrogenic factors?
Orthodontic movement
Restorative dentistry
pathological factors?
Plaque indices
Inflammation (smoking)
mechanical forces?
faulty toothbrushing
Oral piercing
Occlusal injury
Predisposing factors for recession? (anatomy)
Bone dehiscence
Bulbous root structure / enamel pearls
Frenal attachment - hard to clean and caused localised recession
Inadequate keratinised tissue
Gingival biotype (thickness)
precipitating factors (anatomy) ?
Tooth position in the dental arch
Malocclusion
I give biotype?
Thicker = less likely for recession
- brushing alone doesn’t, biotype does
thin biotype?
Under 1.5 mm
thick biotype?
Over 2mm
enamel pear and recession?
Localised recession of bone and causes recession
Pathological factors and results from healing?
Recession as a mode of tx is a good thing
Bones is reduced but masked by inflamed gums, due to inflammatory infiltrate
PMPR, and gums are less inflamed
Black triangles, sensitivity and recession appear, root caries, mobility
(Balloon on head)
classification of recession?
Millers
Class 1
Class 2
Class 3
Class 4
OLD
New classification of recession?
RT1: REC with no loss of interproximal CAL
- interproximal CEJ is not visible
RT2: REC its loss of interproximal CAL
- interproximal loss of CAL is less than or equal to buccal CAL loss
RT3: REC with loss of interproximal CAL
- interproximal loss of CAL is greater than loss of bone
tx for gingival recession?
preventaive care
Non-surgical correction defects
- gingival denture to cover black triangles
Surgical care (repositioning of pt gums)
- pellicle soft tissue grafts
- soft tissue grafts
- guided tissue regeneration
2 broad causes of recession?
moved tooth towards the bone or bone towards the tooth
