Sir, in the paper by Singh, Mizrahi and Korb, which reviewed cases that appeared before the GDC Professional Conduct Committee (BDJ 2009; 206: 217–223) there is an error relating to the sanctions which currently may be applied by the Committee, when a dental professional's fitness to practise is impaired (page 218).

Erasure [from the Register] is for not less than five years, and not for up to five years as stated. In fact, erasure is permanent and is not for any fixed term. However, an erased registrant may apply to the Council for restoration to the Register after not less than five years. The application must be approved by a further hearing of the Professional Conduct Committee.
