Proinflammatory State in the Odontogenesis of Fetuses Exposed to Different Types of Fatty Acids during Pregnancy.

Objectives: The aim of the present study was to analyze the possible changes caused by the maternal ingestion of different types of fatty acids during pregnancy in the proinflammatory state in the odontogenesis of the fetuses.

Subject And Methods: Twenty-four jaws (n = 6 per group) of Wistar rats were collected on the 20th day of intrauterine life. Mothers were separated on the first day of pregnancy into 4 groups according to diet, as described below: control group (C) - diet with soy oil as a source of fat; saturated fatty acid group (S) - diet with lard in saturated fatty acids; trans-fatty acid group (T) - diet with vegetable fat, rich in trans-saturated fatty acids; and polyunsaturated fatty acid (PUFA) group - diet with fish oil, rich in PUFAs.
