Dear editor

Regarding the above article in the January/February issue of Dental Update, I think that the legends for Figures 8 and 9, respectively, have been transposed. The legend beneath Figure 8 should be under Figure 9 and the legend beneath Figure 9 should be under Figure 8.

In addition, I think that it may be of benefit to the readers that the authors advise, when carrying out an intra-oral examination, that the dentist asks a patient to touch the hard palate with the tip of the tongue to enable a thorough examination of the floor of the mouth and the ventral surface of the tongue.
