Sir, I wanted to comment about the letter from K. Parker and J. Patel (BDJ 2013; 214: 93–94). The comments I would wish to make are a) the tooth in question is clearly a lower right seven (not a six as stated) and (b) had the post been placed inside a healthy distal root of a restorable permanent second molar tooth its length and diameter would probably have been acceptable. This case clearly illustrates not the importance of using a correctly sized post, but inadequate knowledge of dental anatomy and a woeful lack of attention to detail by all concerned.
