| Local anaesthetics (local analgesics): use in dentistry |
Two often-confused words are analgesia and anaesthesia. Analgesia is ‘the removal of pain sensation’ whereas anaesthesia is ‘the loss of sensation in general’ (including pain). This difference in meaning is often lost, with many people (and publications) using the terminology ‘local anaesthesia’ when ‘local analgesia’ is what is meant. Local analgesia is the effect that dental practitioners aim to achieve in normal clinical activity; however, ‘local anaesthesia’ is the term commonly used in medicine and dentistry, and is used in this publication.
