Results: pregnant women do not attend dental care due to the following factors: They live far from the health center, X2 = 12 P = 0.0003 (IC95% = 1.05- 1.21). RR = 1.12.OR = 1.86. They do not consider oral health important during pregnancy, they give low rating to the importance of going to the dentist during pregnancy: X2 = 8.65 P = 0.001 (95% CI = 1.04 - 1.19). RR = 1,11.OR = 1,85. Fear of going to the dentist for cultural beliefs, cite malformations in the fetus, abortion, fainting: X2 = 47.05 P = 0.0000. (95% CI 1.18-1.37). RR = 1,27.OR = 3,66. They do not know that dental care in pregnancy is free: X2 = 66.36 P = 0.0000. (95% CI 1.27-1.41). RR = 1.34. OR = 17.74. They were not referred to interconsultation with the dentist, during prenatal checks: X2 = 92.61 P = 0.0000. (95% CI 1.34-1.68). RR = 1.50.OR = 5.61. Unawareness of dental care in pregnancy, when there is dental pathology: X2 = 207 P = 0.000000 (IC95% = 1.56 - 1.90). RR = 1.72.OR = 25.89.
