Letters to the editor

I was offered a copy of the September Dental Update on visiting the George Warman Stand at Dental Showcase back in October and, whilst reading through this publication on the train home, I came across the article written by Bryan Murchie of Newcastle Dental Hospital on the subject of Gagging – Part 2. As this subject is something of interest to me, I read through it, particularly the paragraph relating to Conscious Sedation – which is my area of expertise. However, I was puzzled by the reference to Figure 3 and its connection to inhalation sedation. Surely, the reader would have expected to see depicted an inhalation sedation flowmeter or something similar – the item of equipment in Figure 3 is certainly not one of those and would appear to be some form of monitoring equipment. I am aware that they have quite a number of inhalation sedation machines at Newcastle Dental Hospital, so why could not one of those be shown? This reference picture can only serve to confuse the reader.
