Last month, Dental Tribune International (DTI) covered a new study on how lipid metabolism and maternal weight influence orofacial cleft (OFC) risk in infants, based on research done in Thailand. The study indicated that mothers outside normal weight ranges and those with low levels of high-density lipoprotein cholesterol (HDL-C) are more likely to have infants with OFC. DTI spoke with one of the researchers, Dr Waranuch Pitiphat of Khon Kaen University in Thailand, about the results.
