hypersensitivity Flashcards
What is dentinal hypersensitivity characterised as?
Short, sharp pain in response to stimuli
What stimuli may trigger hypersensitivity?
- Thermal
- Tactile
- Chemical
- Osmotic
the tacky cheeseball osscilates
What might cause dentinal hypersensitivity?
Exposure of dentine due to:
- Gingival recession and loss of cementum
- Loss of enamel
- Absence of smear layer
- Anatomy of CEJ
- Dental/other factors
What is dentinal hypersensitivity characterised by?
- Thermal stimuli to hot or cold drinks
- short, sharp pain from exposed dentine
- no other symptoms of dental defect or pathological condition
- possible plaque induced gingival recession
What is some home care advice for dentinal hypersensitivity
- desensitising agents
- fluoride toothpastes
What are the means of desensitising
- occlude dentinal tubules
- desensitise nerve endings
- form secondary dentine
What are some products to reccommend for hypersensitivity?
- tooth mousse
- colgate sensitive pro relief
- sensodyne toothpastes
How does tooth mousse work
- CPP/ACP binds to teeth and deposits calcium and phosphate in dentinal tubules- also prevents caries and promotes remin
How does colgate sensitive pro-relief work?
- Arginine occludes dentinal tubules as does calcium carbonate
What are the clinical aspects of healthy gingiva?
- uniform pale salmon pink colour
- firm, resilient consistency
- bleeding 10% or less
- stippled appearance (attached)
- knife edged, snug curved attachment, sharp interdental papilla
- 1-3mm probing depth
What are radiographical aspects of healthy gingiva?
- lamina dura firmly attached
- no changes of periodontal ligament space
- no presence of calculus
- normal bone levels (parallel with bone level and CEJs on teeth)
Clinical aspects of gingivitis
- red, bluish pink
- fibrotic
- soft and spongy, dents easily
- 10% or more bleeding
- loss of stippling-shiny
- irregular margins from oedema
- may be rounded, rolled or bulbous
- enlarged due to excess fluid
- may be retractable with air
- 4+ mm probing depth
- apical migration below CEJ
Radiographical aspects of gingivitis
- calculus visible
- radiolucency in furcal area
Clinical aspects of periodontitis
- extensive BOP/PPD
- furcation involvement
- tooth mobility
- ridge defect
- tooth loss
- purulent exudate
Radiographical aspects of periodontitis
- evidence of clinical attachment loss
- vertical/horizontal bone loss
- furcation involvement
- abcess
- widening of PDL
