I noticed a minor error on a card. I browsed through their website but the error is not listed. Does anyone else notice error/typos on the decks? If so, please post. 2006-07 Decks: Dental Anatomy and Occlusion (Eruption) At age of 11 months, according to the card, there are mandibular, maxillary central, lateral incisors and first molars. There shouldn't be first molars. First molars erupt between 12-16 month.
