(in the UK)
Regulations which provide for the enrolment and regulation of dental hygienists and dental therapists. These regulations were amended by statutory instrument in 2002. The amendments extend the work permitted to be carried out by dental hygienists to include removal of excess cement, taking impressions, administration of inferior dental nerve block anaesthesia, and replacing crowns which have been dislodged with a temporary cement. They are also permitted to carry out dental work on a patient under local or regional block anaesthesia administered by a registered dentist, or, provided there is a registered dentist in the room in which the dental work is carried out throughout the procedure, under conscious sedation.
