Periodontal diseases are a threat to women of all ages

Periodontal diseases are a threat to women of all ages
Two new studies in the June issue of the Journal of Periodontology (JOP) suggest that periodontal diseases are a threat to women of all ages due to hormonal fluctuations that occur at various stages of their lives.

One study looked at 50 women who were between the ages of 20 to 35 with varying forms of periodontitis. The study found that women who currently were taking oral contraceptive pills had more gingival bleeding upon probing and deeper periodontal pockets (signs of periodontitis) than those who were not taking oral contraceptive pills.

"Younger women often think that periodontal disease is a condition associated with old age," explained study author Brian Mullally, PhD. "Our study shows that it is very possible for younger women to experience periodontal disease. It is important for women to alert their dental practitioners of any medications they are taking, such as oral contraceptive pills, because it is possible that their oral health may be affected. It might also be prudent where possible for young women to ensure that their periodontal health has been checked before commencing oral contraceptive therapy."

Another study in this month's issue of the JOP examined 1,256 postmenopausal women and looked for a potential association between periodontal bacteria and bone loss in the oral cavity. The study results showed that women with periodontal bacteria in their mouths were also more likely to have bone loss in the oral cavity, which can lead to tooth loss if not treated.

"Our study's findings are important for postmenopausal women because they suggest that good periodontal health is extremely important in the postmenopausal years," said study author Renee Brennan, PhD. "We found that oral bone loss was associated with presence of oral bacteria. In fact, 62% of the women in our study had at least one species of subgingival bacteria present, and the women with these bacteria had more evidence of oral bone loss. Interestingly, women who had a Body Mass Index in the overweight range were much more likely to have oral bone loss associated with presence of oral bacteria. Oral bone loss has been associated with osteoporosis in this group as well. This association has been difficult to study because many risk factors for periodontal disease and osteoporosis, including smoking, age, medications, and overall general health are similar. It should be noted that our study was limited in that it included a relatively healthy group of mostly Caucasian women and that future studies are needed to determine the effects of periodontal bacteria on bone loss in other groups of postmenopausal women."

"Taking care of your teeth and gums is a lifelong commitment," explained Preston D. Miller, Jr., DDS, President of the American Academy of Periodontology. "Women should pay special attention to their oral health as they enter different stages of their lives because additional periodontal care may be needed during different points such as the reproductive years or menopause. Knowing your ,pocket size, depth can be a good way for women to keep track of their periodontal health; periodontal pockets of one to two millimeters with no bleeding are not a concern but pockets of three and four millimeters may need a more in depth cleaning called scaling and root planing."

FDA Approves 'No-Period' Contraceptive Pill

Lybrel, a birth-control pill that does away with a woman's monthly period, was approved Tuesday by the U.S. Food and Drug Administration.

The estrogen-progestin hormonal pill differs from traditional birth-control pills in that it does not include the "week off" of placebo pills that leads to a cessation of artificial hormones and bleeding.

Lybrel is described as "continual contraception" but it "works the same way as the 21-days on, seven-days off [pill] cycle -- it stops the body's monthly preparation for pregnancy by lowering the production of hormones that make pregnancy possible," Dr. Daniel Shames, deputy director of the FDA's Office of Drug Evaluation III, at the Center for Drug Evaluation and Research, explained at a press conference late Tuesday.

A majority of women who decide to take Lybrel will encounter unscheduled bleeding, or spotting, that in most cases tapers off over the first year of use, Shames said. In the primary clinical trial leading up to approval, 59 percent of women who took Lybrel for one year reported no bleeding or spotting during the last month of the trial.

In terms of safety, two one-year clinical trials involving more than 2,400 18-to-49-year-old women showed no increased risk of endometrial cancer among those taking Lybrel. The risks of other side effects linked to the birth-control pill -- primarily blood clots -- were similar to those seen in other contraception regimens, Shames said.

"We don't expect any surprises in terms of long-term use of this product," he added, although he noted that the FDA has requested that the drug's maker, Wyeth Pharmaceuticals, conduct post-marketing studies to keep tabs on Lybrel's long-term safety.

Despite some women's reticence to do away completely with their monthly period, gynecologic experts agreed that there was no physiological "downside" to a period-free life. In fact, one expert noted that, for decades, many American women have been pharmaceutically ending their periods with more traditional birth-control pills with no resulting problems.

"There were other products, such as the long-acting progestin, Depo-Provera, that was given by injection," said Dr. Michael Petriella, vice chairman of obstetrics and gynecology at Hackensack University Medical Center, in Hackensack, N.J. "Women who were using that for contraception wouldn't get their period at all while on that product."

And for years, "some physicians have been allowing some women to take the Pill off-label -- allowing them to take two packages continuously, for example," Petriella said.

Another expert noted that the "period" women get while on conventional birth-control pills isn't connected to a natural cycle of egg production, anyway.

"It's not a natural period. It's an artificially induced period that happens because she stops taking the hormones for seven days. So, she gets some vaginal bleeding," explained Dr. Camelia Davtyan, an internist specializing in women's health and an associate professor of medicine at the University of California, Los Angeles.

In fact, a no-period pill like Lybrel could have been a contraceptive norm for women from the get-go, Davtyan said. However, the doctors and pharmaceutical companies who developed the birth-control pill back in the 1960s assumed that women would want a regimen that mimicked the monthly cycle.

"I guess they were trying to make it seem as 'real' as possible and cause as little change as possible in a woman's life," Davtyan said.

But times have changed, and newer contraceptive products such as Seasonale -- a contraceptive pill that cuts the number of periods to just four a year -- have already been readily embraced by some American women over the past decade.

Davtyan said she has recently noticed a big shift in her patients' attitudes toward their period.

"They want convenience, and they tell me that they'd just rather not have the bleeding altogether so that they don't have any limitations with sports, with having to use pads, tampons," she said. "And the younger the woman, the more likely that she will want her periods stopped. It's very possible that this will be the wave of the future."

But Petriella said many women still feel a strong psychological attachment to their period and do not want to give it up, however inconvenient it may be.

"Sometimes [ending periods] is just emotionally uncomfortable for women," he said. "They don't feel right about not having their period. For those women, obviously Lybrel and other such products are not good products for them."

Petriella believes that, at least in the short-term, Lybrel will appeal to only a minority of women. They include those with menstruation-linked conditions such as endometriosis and menstrual migraine, or those who have already tried -- and liked -- period-limiting products such as Seasonale, he said.

As with any pharmaceutical contraceptives, women who decide to go on Lybrel may experience random breakthrough bleeding, Davtyan said.

So, for the 59 percent of women who have no bleeding or spotting after one year, "I think Lybrel is a great deal," Davtyan said. "For the remainder, if they have the patience to hang in there for a few months, the spotting might abate. There will be an occasional patient that will continue to spot, and then, clearly, it's a better deal to have a scheduled period than to start spotting at an unknown time and maybe in an uncomfortable circumstance."

Women who decide to resume their monthly cycle -- for example, those who wish to become pregnant -- can typically expect to resume their normal cycle within days of stopping Lybrel, Shames said. He said that short timespan to resumption of ovulation could leave women who skip or miss pills open to unplanned pregnancy, so the FDA is advising that women consider a second form of birth control while on Lybrel, as a safeguard.

Both Davtyan and Petriella stressed that young women who are considering a pharmaceutical end to their period should not be concerned that doing so will harm their health.

"Remember, there's no real physiological value to hold on to the period that a woman has while she is taking the Pill, unless it is a psychological value, which I respect," Davtyan said.

Conjugated estrogen and medroxyprogesterone combinations

What is the most important information I should know about conjugated estrogens and medroxyprogesterone?

Conjugated estrogens increase the risk of developing endometrial hyperplasia, a condition that may lead to cancer of the lining of the uterus. Taking a progestin, such as medroxyprogesterone, with conjugated estrogens lowers the risk of developing this condition. Visit your doctor regularly and report any unusual vaginal bleeding right away.

The Women's Health Initiative (WHI) study found an increased risk of breast cancer, heart disease, nonfatal heart attacks, and blood clots in women taking estrogen and medroxyprogesterone combinations long-term. You should contact your doctor or healthcare provider to discuss your individual risks and benefits before taking a conjugated estrogen and medroxyprogesterone combination long-term.
