Dentine Hypersensitivity

what is dentine hypersensitivity

pain aries dorm exposed dentine typically in response to chemical, thermal or somatic stimuli that cannot be explained as arising from any other dental defect

what is within dentine

Collagen

Mucopolysaccharides

Processes of odontoid blasts

where do odontoblasts lie

at the pulp periphery and the processes extend into the adj

what is secondary dentine

dentine produced after the tooth is fully formed and is peripherally deposited on the roof and floor of the pulp chamber

what is tertiary dentine

dentine produced as a response to pulpal insult from noxious stimulus

how do we prevent dentine hypersensitiivity

Remove cause of possible

Occlude tubules

Tooth devitalisation eg root canal

Dietary advice

OH TIPPS

what desensitising agents are there

sodium flouride

stanous flouride gel

Sodium monoflouriphopshate

ca oh

Strontium/potassium chloride

formaldehyde

resin and adhesives

what is sodium flouride as a desentising agent

applied frequently, used as pastes and gels mouthwashes

Fluoride from sodium salts is taken into dentine making it more resistant to acid decalcification. Promotes secondary dentine formation to block dentine tubules

what is Sodium monoflouriphopshate as a desensitising agent

fluoride salt in toothpaste uncertain as a desentivivity agent
