Effects of isotretinoin on new bone formation after maxillary sutural expansion

Correction to: J Orofac Orthop (2020) 81:440–446 https://doi.org/10.1007/s00056-019-00209-2 The original version of this article unfortunately contained a mistake. The third bullet under the section Materials and Methods should read “Soybean oil (SOY) group: Soybean oil was administered via oral gavage (2 ml/kg) during the nursery period before expansion (an interval of 40 days), and during the expansion (period of 5 days) + retention period (period of 12 days—a total of 57 days)” instead of “Soybean oil (SOY) group: Soybean oil was administered via oral gavage (0.2 ml/kg) during the nursery period before expansion (an interval of 40 days), and during the expansion (period of 5 days) + retention period (period of 12 days—a total of 57 days)”.
