Please review the article entitled “Dental arch dimensional changes after adenotonsillectomy in prepubertal children” (Caixeta ACP, Andrade I Jr, Pereira TBJ, Franco LP, Becker HMG, Souki BQ. Am J Orthod Dentofacial Orthop 2014;145:461-8) for an error. After reading it a few times, I think there is a contradiction. Table I and the second sentence of the Discussion report “a shorter mandibular arch length” for the MB group, whereas the last sentence of the Abstract and the Conclusions state the opposite. Please let me know if this is correct.
