摘要:Tooth decay in pregnant women is frequent; the Cariogram is a useful tool for the identification of risk factors for dental caries. The aim is to determine risk to dental caries in pregnant women. A convenience sample of 55 healthy women between 18 and 40 years old in their last trimester of pregnancy, recruited from public hospitals of the State of Mexico, were studied. According to Cariogram factors 58% of patients can develop new carious lesions, due to their diet and presence of cariogenic bacteria (20%), susceptibility (11%) and circumstances (7%). The Cariogram is an efficient tool to identify caries risk factors in pregnant women. A correlation was observed between the identified factors and the Decayed Missing, Filled, Teeth surfaces Index (DMFT).
