Periodontal and Gingival Diseases among Pregnant and Non-pregnant Women in Some Selected Tertiary Care Hospitals in Dhaka, Bangladesh

The mouth is often treated as a separate world from the rest of the body, a place for chewing and speaking that operates independently of our general health. Yet, the tissues holding our teeth in place are deeply connected to our overall well-being, reacting to changes in our hormones, immune system, and daily habits. Among the most common issues affecting these tissues are gum diseases. One form, known as gingivitis, is an inflammation of the gums that causes them to become red, swollen, and prone to bleeding when touched. If left unchecked, this condition can progress to a more serious state where the structures supporting the teeth begin to break down, leading to deeper gaps between the gum and the tooth and potentially causing teeth to loosen. While these conditions can affect anyone, the body undergoes profound shifts during pregnancy. Hormonal surges can alter how the gums respond to bacteria, sometimes making them more sensitive and inflamed. This biological reality raises a critical question for public health: does the state of pregnancy itself make women more vulnerable to these oral problems compared to women who are not pregnant, and if so, what does that mean for the care they receive?

In a recent investigation conducted in Dhaka, Bangladesh, researchers set out to answer this question by looking directly at the mouths of women visiting major hospitals. The team, led by scientists from the Bangladesh University of Professionals and other local institutions, focused on two distinct groups: women who were currently pregnant and women of childbearing age who were not. They examined a total of 229 women, mostly between the ages of 25 and 34, who were seeking care at tertiary hospitals. The researchers did not rely on what the women said they felt; instead, they performed careful clinical checks. They looked for signs of plaque, a sticky film of bacteria that builds up on teeth, and measured the depth of the pockets between the gums and teeth. They also checked for bleeding when gently probing the gums, a clear sign of inflammation, and looked for gum recession, where the gum line pulls back from the tooth. Alongside these physical exams, the team asked the women about their daily habits, such as how often they brushed, whether they used dental floss, and what kind of food they preferred.

The results painted a clear picture of a significant difference between the two groups. Pregnant women showed a much higher burden of gum disease. When the researchers examined the level of inflammation, they found that nearly 79 percent of the pregnant women had moderate to severe inflammation, a figure that stood in stark contrast to the non-pregnant group, where only about 39 percent showed similar levels of severity. This difference was not just a matter of redness; it extended to bleeding. More than half of the pregnant women experienced bleeding when their gums were probed, compared to roughly 37 percent of the non-pregnant women. The physical structure of their mouths also told a story of greater distress. About 26 percent of the pregnant women had periodontal pockets that were 3 millimeters deep or more, a sign of more advanced disease, whereas only about 5 percent of the non-pregnant women had pockets of that depth. Furthermore, gum recession was far more common among the expectant mothers, affecting nearly 60 percent of them, compared to just under 20 percent of the non-pregnant group.

These physical findings were mirrored by differences in daily habits. The study revealed that pregnant women were less likely to maintain a regular tooth-brushing routine, with about 80 percent brushing regularly compared to nearly 99 percent of the non-pregnant women. The gap was even wider when it came to more thorough cleaning methods; a large majority of pregnant women did not actively clean their teeth and tongues beyond a simple rinse, whereas fewer non-pregnant women skipped this step. Perhaps most telling was the lack of professional care. Only a tiny fraction of the pregnant women, just 5.6 percent, had visited a dentist for a check-up during their pregnancy. This suggests that despite the heightened risk and the visible signs of inflammation, the pregnant women in this study were not receiving the dental attention they needed. The researchers noted that while the women generally preferred home-cooked food, which is often healthier, the combination of hormonal changes, reduced brushing frequency, and a lack of dental visits created a perfect storm for gum disease.

The study also looked at other health factors, finding that while conditions like high blood pressure were slightly more common in the non-pregnant group, diabetes was more frequently reported by the pregnant women. This adds another layer of complexity, as diabetes is known to affect gum health. The researchers concluded that pregnancy appears to act as a catalyst for gum disease, likely due to the body's hormonal response, which makes the gums more reactive to the bacteria that are always present in the mouth. The findings suggest that the standard approach to prenatal care in this region may be missing a crucial component: oral health. By identifying that pregnant women are not only more susceptible to gum disease but also less likely to practice consistent hygiene or seek professional help, the study points to a clear need for change. It indicates that dental care should be woven into the fabric of prenatal check-ups, ensuring that mothers receive the education and treatment necessary to protect both their own health and the well-being of their developing children. The evidence gathered in Dhaka serves as a reminder that the health of the mouth is not an isolated concern but a vital part of the journey through pregnancy.
