What is chloroethane used for?
4
It is used in dentistry as one of the means of diagnosing a ‘dead tooth’
A small amount of the substance is placed on the tooth and because of the low boiling point of the liquid this creates a localised chilling effect
If the tooth is still alive this chilling should be felt by the patient
