Female
Age
18 Years to 40 Years

Inclusion criteria

Inclusion criteria: Be between 18 and 40 years old; during the 3rd trimester of pregnancy, between the 27th and 39th gestational week; with regular follow-up with the obstetrician; with adequate cognitive function during pregnancy; with no problem that required absolute rest

Exclusion criteria

Exclusion criteria: Twin pregnancies; individuals with neuromotor impairments; arterial hypertension during pregnancy; Gestational Diabetes Mellitus; malnutrition; overweight, therefore, body mass index between 25.00 and 29.99 kg/m2; confirmed or suspected diagnosis of SARS-CoV-2 infection; hyposalivation; subjects who were using or who used at some point in pregnancy antibiotics or any medication that could interfere with periodontal status or salivary flow, e.g. immunosuppressive drugs, anticonvulsants or calcium channel blockers; who were under orthodontic treatment or any dental treatment with another professional; with multiple tooth loss, so more than two teeth per hemiarch; self-reported systemic disease besides obesity; and users of alcohol, tobacco, and illicit drugs

Design outcomes

Primary

MeasureTime frame
Expected outcome 1. Using proton nuclear magnetic resonance spectroscopy analysis, we expected to identify dysregulation in salivary and plasma metabolite levels associated with obesity and periodontitis during pregnancy, particularly when obesity and periodontitis were present in combination;Identified outcome 1. Using a proton nuclear magnetic resonance spectrscopy analysis, this study demonstrated a more evident difference among groups in saliva samples compared to plasma, mainly related to periodontitis, without notable differences related to obesity. Periodontal parameters were positively correlated with many saliva metabolites, for instance, it was found a dysregulation in the salivary levels of leucine, ornithine, isovaleric acid, valine, isoleucine, putrescine, taurine, phenylalanine, propionic acid, and acetic acid associated with periodontitis
