About this trial

This study aims to better understand how pregnancy affects the health of the gums and tissues that support the teeth. During pregnancy, hormone levels (like estrogen and progesterone) increase significantly. These hormonal changes can cause many changes in the body, including in the mouth. Some pregnant women may notice that their gums become swollen, red, or bleed more easily - this is called pregnancy gingivitis. It happens more often during the second and third trimesters and usually improves after birth. Even if a pregnant person has good oral hygiene, hormonal changes may still make the gums more sensitive to plaque and bacteria. Scientists believe that these changes in gum health are linked to how the body responds to hormones, bacteria in the mouth, and changes in the immune system. To explore this further, saliva samples will be collected from:

* Pregnant women during their 1st, 2nd, and 3rd trimesters * The same women again 6-8 weeks after giving birth * A group of non-pregnant, healthy women as a comparison group The investigators will use a scientific method called untargeted metabolomics to study these saliva samples. This method helps looking at small substances (called metabolites) in saliva to see if there are any patterns related to pregnancy and gum health.

The goal is to identify biological changes that happen during pregnancy and understand how they might affect the gums. This research will help improve early detection and prevention of gum problems during pregnancy in the future.

Trial outcomes

Primary outcomes

1

Salivary Metabolite Profile by Pregnancy Status

Untargeted metabolomic analysis of saliva samples will be performed using LC-MS/MS to identify metabolite patterns associated with different stages of pregnancy and periodontal status. Results will be reported as relative metabolite concentrations (normalized intensity, arbitrary units).

Time frame
Baseline, 1st trimester (0-13 weeks), 2nd trimester (14-27 weeks), 3rd trimester (28 weeks and later), and 6-8 weeks postpartum

Secondary outcomes

1

Bleeding on Probing (BOP)

Bleeding will be recorded at six sites per tooth using gentle probing. The outcome will be reported as the percentage of bleeding sites per participant.

Time frame
Baseline, 1st trimester (0-13 weeks), 2nd trimester (14-27 weeks), 3rd trimester (28 weeks and later), and 6-8 weeks postpartum
2

Plaque Index score

Plaque accumulation will be assessed using the Silness-Löe Plaque Index (range: 0-3). The mean plaque index score per participant will be reported.

Time frame
Baseline, 1st trimester (0-13 weeks), 2nd trimester (14-27 weeks), 3rd trimester (28 weeks and later), and 6-8 weeks postpartum
3

Mean probing depth (PD)

Probing depth will be measured in millimeters (mm) at six sites per tooth. The average probing depth per participant will be reported.

Time frame
Baseline, 1st trimester (0-13 weeks), 2nd trimester (14-27 weeks), 3rd trimester (28 weeks and later), and 6-8 weeks postpartum
