Recent evidence suggests that these parasites may contribute to increased inflammation and tissue destruction, potentially playing a role in the etiology of gingivitis and periodontitis.\n\nThe study will include 120 participants aged 18 and older who meet the inclusion criteria. Following the collection of demographic data and oral hygiene habits via a questionnaire, a single calibrated examiner will perform comprehensive clinical periodontal examinations. Measurements will include plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing pocket depth (PPD), clinical attachment loss (CAL), and gingival recession (GR) based on the 2017 World Workshop Classification of Periodontal and Peri-Implant Diseases and Conditions.\n\nTo detect the presence of parasites, unstimulated whole saliva samples and subgingival plaque samples from the deepest periodontal pockets will be collected from each participant. These samples will be analyzed immediately at the Parasitology Laboratory using light microscopy (10X and 40X magnification) to identify live trophozoites.

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:\n\n* Pregnant women during their 1st, 2nd, and 3rd trimesters\n* The same women again 6-8 weeks after giving birth\n* 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.\n\nThe goal is to identify biological changes that happen during pregnancy and understand how they might affect the gums.
