CHICAGO — September 21, 2005 — Beginning in 2007, daylight savings time will be extended by almost a month. This additional amount of daylight may also help extend the life and health of people’s teeth and bones. That’s because vitamin D, also known as the “sunshine vitamin,” is made by the body through casual and minimal sun exposure. Vitamin D is just as essential as calcium for healthy teeth and bones according to a paper that was published in the September issue of the Journal of Periodontology. Study Abstract *

“Both vitamin D and calcium counteract deficiencies and reduce bone resorption,” said Dr. Charles Hildebolt, Department of Radiology, Washington University School of Medicine, St. Louis, MO. “Numerous studies indicate that vitamin D and calcium deficiencies result in bone loss and increased inflammation. Inflammation is a well recognized symptom of periodontal diseases, which is why it has been suggested that calcium and vitamin D deficiency may be a risk factor for periodontal diseases.”

Research shows that the best means of obtaining the required amount of vitamin D is from sunshine. According to the National Institutes of Health, season, geographic latitude, time of day, cloud cover, smog and sunscreen affect ultraviolet ray exposure and vitamin D synthesis. Ten to 15 minutes of sun exposure at least two times per week to the face, arms, hands or back is usually sufficient to provide adequate vitamin D. People who live in an area with limited sun exposure may want to eat foods fortified with vitamin D such as milk, eggs, sardines and tuna fish.

“We are not encouraging people to forego their sun protection, nor to spend prolonged periods of time in the sun” said Vincent J Iacono, DMD and president of the American Academy of Periodontology. “According to the American Academy of Dermatology, there is no such thing as a total UV block. Even the most effective sunscreens currently on the market let through enough UV to allow for adequate vitamin D formation.”

Periodontal diseases are bacterial infections that, if left untreated, may cause damage to the bone and even tooth loss. A number of infectious diseases have been linked with low levels of vitamin D, and it has been demonstrated that vitamin D can suppress proinflammatory cytokine production. (Proinflammatory cytokines are molecules that have destructive effects throughout the body.)

“Periodontal disease increases the production of cytokines, but it has been demonstrated that vitamin D can suppress cytokine production, and possibly decrease the risk of periodontal disease,” explains Hildebolt.

“Further research is needed to define the health risks associated with inadequate levels of vitamin D and calcium intake and how they affect periodontal diseases,” said Iacono. “Until we have further information, it is prudent for patients to talk to their healthcare providers about the possibility of taking vitamin D and calcium supplements.”

CHICAGO – March 19, 2001 – Crocodiles, poisonous snakes and the scorching sun are not the only things the Survivors have to fear. Neglected oral hygiene may also put the survival of their teeth at jeopardy, as well as increase the risk that an infection in their mouth could spread and put other parts of their body at peril.

Early in the game, Survivor‘s Kucha tribe won a reward challenge that included in the prize toothbrushes and toothpaste. The other Survivor contestants’ lack of oral hygiene and their soft diet with little nutritional value could cause periodontal problems to flare up. Bacterial plaque, a sticky, colorless substance that forms on the teeth constantly, can turn into a hard substance called calculus in less than two days. If calculus develops below the gums onto the tooth root, it can irritate the gums, causing infection.

A Journal of Periodontology study followed a group of 15 third-year dental students who gave up oral hygiene activities for 21 days to monitor the effects on their oral health. By day 21, all subjects exhibited signs of gingivitis, including plaque and overt clinical inflammation. The toxins produced by gingival infections can destroy the supporting tissues around the teeth, including the bone. When this happens, gums separate from the teeth, forming pockets that will fill with even more plaque and infection. As the disease progresses, these pockets deepen, more gum tissue and bone are destroyed and the teeth eventually become loose. In addition to being a major cause of tooth loss, periodontal disease has been linked to serious health threats such as heart attacks, diabetes and preterm births. Study Abstract *

“While most people don’t have to worry about not being able to brush their teeth for several days, they should understand that plaque, when not removed, can harden to the point it can only be removed during a professional cleaning after only a day or two,” said Michael McGuire, D.D.S., president of the American Academy of Periodontology (AAP). “When people don’t floss daily, plaque builds between the teeth, and periodontal disease often begins between teeth where a toothbrush can’t reach.”

One possibility for people without access to toothbrushes and floss may be to chew on sticks. Dental researchers have studied the periodontal status of Sudanese populations who use Miswak chewing sticks and found that their periodontal health status was comparable to Sudanese toothbrush users.

CHICAGO – January 30, 2003 – Canadian researchers found that patients with Kindler syndrome had an earlier onset of periodontitis and that the disease progressed more rapidly than in non-Kindler patients. Study findings were published in the January Journal of Periodontology. Study Abstract *

Researchers believe Kindler syndrome is caused by an unidentified genetic disorder that gives the appearance of two congenital diseases of the skin, epidermolysis bullosa dystrophia and poikilodoerma. Epidermolysis bullosa dystrophia is a condition in which the skin and mucous membranes are fragile. Any friction or trauma to skin and/or mucous membranes causes blisters and the skin to come off. Poikiloderma is a condition characterized by pigmentary and atrophic changes in the skin, giving skin a spotted appearance.

The study looked at 31 patients (18 with Kindler syndrome and 13 without) from rural Panama to determine the extent to which periodontal disease is associated with Kindler syndrome.

“The major finding of this study was that individuals with Kindler syndrome develop periodontitis at an earlier age and the disease progresses rapidly,” said Colin Wiebe, D.D.S., study author and periodontist at the University of British Columbia. “Therefore, we believe it is important to include Kindler syndrome in the category of medical disorders predisposing to destructive periodontal disease.”

Definition criteria for periodontitis in this study was clinical attachment loss (CAL) of at least 4 mm. Based on this criteria, 72 percent and 46 percent of the Kindler and control patients respectively had periodontitis. The median age for Kindler patients with periodontitis was 17 years, and the only Kindler patients without periodontitis were under 10 years old. In the control group, patients with periodontitis had a mean age of 35 years and only one patient under 20 had periodontitis.

Kindler patients had an average CAL of 6 mm by age 20, while it was estimated to take 60 years to accumulate the same level of destruction in the control groups.

“Previous studies have suggested a link between periodontal disease and Kindler syndrome, but this study confirms the risk these patients have for developing periodontitis at a much younger age than a dentist would normally expect,” said Gordon Douglass, D.D.S., president of the American Academy of Periodontology.

He continued, “Of considerable interest is the additional information that can be learned about the relationship of periodontal disease and the genetic defect of these patients. Once the defect has been identified, we can take the information and apply it to other patients who are genetically predisposed to periodontal disease, which may help us determine positive treatment outcomes for periodontal disease.”

CHICAGO – January 30, 2001 – New research confirms findings that periodontal disease may increase a person’s risk for the respiratory disorder Chronic Obstructive Pulmonary Disease (COPD), the sixth leading cause of mortality in the United States. The study, published in this month’s Journal of Periodontology, also noted a correlation between the amount of periodontal disease and lung capacity. Study Abstract *

For this study, researchers analyzed the periodontal and respiratory health of 13,792 patients. Patients with periodontal disease, defined by mean periodontal attachment loss (MAL) of greater than 3 millimeters, were found to have nearly a one-and-a-half times greater risk of COPD. A distinct trend also was noted in that lung function seemed to diminish with increased periodontal attachment loss. This suggests that periodontal disease activity may promote the progression of COPD.

“Identification of potential risk factors that contribute to the development of chronic bronchitis or emphysema – respiratory diseases that comprise COPD – may suggest interventions that could prevent or delay the onset of the disease, or slow its progression,” explained Frank A. Scannapieco, D.M.D., lead researcher of the study. “Based on these and previous research findings, it is conceivable that improved oral health may help prevent the progression of COPD. This is good news for the estimated 16 million Americans who suffer from it.”

Scannapieco cautioned that research does not conclude that periodontal disease causes COPD. “We know that the onset and progression of COPD is dependent on smoking, and that repeated bacterial infections can worsen the lung disease. It is possible that periodontal bacteria could travel to the lungs through saliva or normal breathing and in some way promote lung infection. Another possibility is that the inflammation caused by periodontal disease may contribute to inflammation of the lining of the lung airway, which limits the amount of air that passes to and from the lungs.”

“For a long time we’ve known that people who smoke, are exposed to environmental pollution, or are genetically predisposed are at increased risk for development of COPD,” explained Michael McGuire, D.D.S., president of the American Academy of Periodontology (AAP). “Now mounting evidence suggests that periodontal disease may work in concert with these factors and contribute to the progression of this disease.”

CHICAGO – Embargoed for Release: October 18, 1999 – Patients referred to periodontists often have no idea they have undiagnosed and uncontrolled health problems, some of which can affect their oral health and dental treatment, according to a study published in the current issue of the Journal of Periodontology. Study Abstract *

Dental patients routinely complete medical questionnaires and review their health histories with dental professionals during their initial visit. The study compared self-reported medical histories from 39 consecutive patients with moderate to advanced periodontal disease to laboratory data obtained when patients were then referred to a hospital for a urinalysis, complete blood count and a standard blood chemistry panel.

While no patients in the study reported having diabetes, 15 percent tested positive for the disease. In addition, only 5 percent of participants reported a history of abnormal cholesterol, while 56 percent tested positive for exceptionally high values, putting them at greater risk for strokes and heart attacks.

“These and other underreported conditions found in the study are alarming because it’s important for patients to know what diseases they have or are at high risk for so that they can take steps to control the diseases,” said the study’s lead researcher, Dr. Kelly Thompson. “From a dental practitioner’s standpoint, these findings also mean that we may not always be made aware of what we’re up against. Undiagnosed and uncontrolled diabetes can have a profound impact on oral health and can greatly affect treatment procedures and outcomes.”

A two-way relationship between periodontal disease and diabetes exists. Diabetics are more likely to develop infections like periodontal disease, and periodontal disease makes it more difficult for people who have diabetes to control their blood sugar. Furthermore, people with diabetes and periodontal disease are more prone to recurrent periodontal abscesses (areas around teeth that are inflamed, infected and painful).

Research also points to a link between periodontal disease and heart disease. People with periodontal disease may be almost twice as likely to suffer from coronary artery disease as those without periodontal disease.

“This suggests that it may be especially important for people with periodontal disease to be aware when they have other risk factors for heart disease, such as high cholesterol,” said Dr. Jack Caton, president of the American Academy of Periodontology (AAP). “The findings also point out one more reason for increased collaboration between the dental and medical communities.”

The study cites a need for dental professionals to emphasize to patients the importance of routine physical examinations and preventative care. “Our patients who exhibit risk factors could benefit from physician referrals,” said Thompson.

CHICAGO – May 30, 2000 – Smoking may be responsible for more than half of the cases of periodontal disease among adults in this country, according to a new study published in the Journal of Periodontology. The study found that current smokers are about four times more likely than people who have never smoked to have advanced periodontal disease. However, 11 years after quitting, former smokers’ likelihood of having periodontal disease was not significantly different from those who had never smoked. Study Abstract *

Researchers analyzed government health data on 13,650 people aged 18 and older who had their teeth. This is the first study to estimate the proportion of periodontal disease cases that can be attributed to cigarette smoking.

“Cigarette smoking may well be the major preventable risk factor for periodontal disease,” said the study’s lead researcher, Scott Tomar, D.M.D., Dr.P.H., of the Division of Oral Health at the Centers for Disease Control and Prevention (CDC). “The good news is that quitting seems to gradually erase the harmful effects of tobacco use on periodontal health.”

The study also found that there is a dose-response relationship between cigarettes smoked per day and the odds of periodontitis. “Smokers who smoked less than a half a pack per day were almost three times more likely than nonsmokers to have periodontitis. Those who smoked more than a pack and a half per day had almost six times the risk,” explains Tomar.

A recent online survey of periodontists conducted by the AAP found that the vast majority of periodontists routinely (79 percent) or most of the time (14 percent) advise their patients to quit smoking.

“Everyday periodontists see the destruction smoking causes in the mouths of their patients,” said Jack Caton, D.D.S., M.S., president of the American Academy of Periodontology. “I hope the staggering statistics from this study will compel even more dental care providers to get involved in tobacco cessation efforts.”

Tobacco’s negative effect on periodontal health is well documented. Smoking interferes with healing, making smokers more likely to not respond to treatment and to loose teeth. “Tobacco use reduces the delivery of oxygen and nutrients to gingival tissue,” explains Robert Genco, D.D.S., Ph.D., editor of the Journal of Periodontology. “Smoking impairs the body’s defense mechanisms, making smokers more susceptible to an infection like periodontal disease.”

In addition to being a major cause of tooth loss, periodontal disease has been linked to increased risk of heart disease, stroke, poorly controlled diabetes, respiratory disease and premature babies.

The American Academy of Periodontology (AAP) has a section entitled The Mouth-Body Connection on its Web site at WWW.PERIO.ORG to educate people about tobacco’s effects on periodontal health.

“We hope smokers will think about the fact that they are putting their teeth and their health at jeopardy,” said Caton. “We encourage smokers who want to quit ask their health and dental care providers for help.”

CHICAGO – November 21, 2001 – Patients who are at risk for losing teeth to periodontal disease show improved prognosis for keeping their teeth following periodontal surgery, according to a new study in the Journal of Periodontology. Study Abstract *

The study evaluated the effects of no treatment, non-surgical therapy, and periodontal surgery on 2,350 teeth of patients who presented with moderate to severe periodontitis. Forty-eight percent of teeth receiving periodontal surgery improved prognosis, while only 12% of the teeth that received no treatment or that underwent non-surgical treatment improved. In addition, more than 35% of the teeth in the no treatment and non-surgical treatment groups actually worsened in prognosis.

“These findings are important for patients who value oral health and want to keep their teeth a lifetime,” explained Stephen Harrel, D.D.S., one of the authors of the study. “It’s essential for these patients to understand that optimal results are not always possible with non-surgical methods and, with no treatment, periodontal disease usually gets worse. Equipped with this understanding and an appreciation of the benefits afforded by natural teeth over dentures, even the most apprehensive patients should consider selecting the treatment option that’s best for them – even if that involves surgery.”

Harrel emphasizes that these findings are significant compared to previous studies that used an overall average “score” for each patient (patient mean) instead of individual teeth to determine the impact of periodontal treatments and non-treatment. “The damage from periodontal disease is often localized, so the individual teeth that have damage should be followed in order to obtain a true picture of treatment results. Results based on patient means can mask positive or negative effects of treatment.”

“This research can help save patients’ smiles by illustrating tooth loss as a consequence of what happens when periodontal disease is ignored and not fully treated,” said Kenneth Bueltmann, D.D.S., president of the American Academy of Periodontology (AAP). “And, as additional research links periodontal disease to other serious health conditions, such as diabetes, heart disease, respiratory disease and pre-term low birth weight, if this study prompts even one patient to select the best recommended treatment plan so to avoid these other possible consequences of ignored periodontal problems, then it’s achieved a positive outcome for the entire healthcare community.”

CHICAGO – November 30, 2000 – New research provides further evidence that a person’s genes play a major role in the onset and severity of periodontal disease. The study, published in a new issue of the Journal of Periodontology released today, concluded that approximately half of the variance in periodontal disease in the population can be attributed to genetic differences. Study Abstract *

The study examined periodontal health in 64 pairs of identical and 53 pairs of fraternal twins. The study found that between 48 and 59 percent of the differences in measures of periodontal disease, such as attachment loss and probing depth, could be attributed to genetics. When correlating eight different clinical measures for periodontal disease among the two types of twins, all eight measures were statistically significant in the identical twins, while only two measures were significantly greater than zero in the fraternal twins.

“Periodontal disease is multifactorial, meaning that susceptibility involves genetic and environmental factors,” explained John C. Gunsolley, D.D.S., M.S., one of the authors of the study. “The basic question of what portion of periodontal disease risk among individuals is genetic versus environmental is important because it may lead to a better understanding of disease susceptibility. Identification of people at high risk for periodontal disease before they even display symptoms may provide new avenues for treatment.”

Gunsolley cautions that there are likely a number of genes that play a role in susceptibility, and these may differ in different races and ethnic groups. “I hope future studies will determine the genetic determinates underlying the risk for periodontal disease,” he said.

Michael McGuire, D.D.S., president of the American Academy of Periodontology (AAP), agrees. “I’m pleased that the role of genetics in oral health continues to be studied. I’m convinced that genetic research, such as the Human Genome Project, is going to revolutionize the way we treat diseases in general, including periodontal disease.”

CHICAGO—October 9, 2007—Patients worried about their postoperative healing times for oral surgery procedures may now find a unique form of relief. A new study in the October issue of the Journal of Periodontology (JOP) found that an adhesive made from an enzyme found in snake venom was a more effective and beneficial adhesive when used to close surgical incisions than traditional sutures. Study Abstract

The study followed 15 patients during the healing process after a gingival (gum) graft. When the adhesive derived from snake venom was used, those patients had faster recovery and better results than those treated with traditional sutures. “This unique type of adhesive may stimulate faster tissue repair. It is a more natural form of adhesive in comparison to traditional sutures used after surgery,” explained study author Monica Barbosa, Phd, Bauru Dental School at the University of Sao Paulo, “More studies are needed to fully evaluate the effectiveness of this alternative.”

“This adhesive may be a less infectious alternative to traditional sutures,” said Preston D. Miller, DDS, and AAP president. “This research highlights the array of therapies available for patients; both traditional and natural alternatives. There continues to be a lot of exciting and innovative research in the field of periodontics.”

CHICAGO–September 18, 2007–A study in the September issue of the Journal of Periodontology (JOP) found that smokers had less desirable long-term results following periodontal plastic surgery than non-smokers. The study followed 10 smokers and 10 non-smokers for two years to evaluate the effects of cigarette smoke on the long-term outcomes of a treatment to help soft tissue reattach to the root surface of the teeth. After two years, residual gum recession around the area which received the surgery was greater in smokers as compared to non-smokers. Study Abstract

Studies have shown that smoking can impair the body’s ability to heal itself immediately after surgery; but, this most recent study also showed that when a patient has periodontal plastic surgery, smoking can damage the ability of that procedure to stay intact over a long period of time.

“People who smoke and have had some sort of periodontal plastic surgery should be aware of the negative side effects of smoking. It can be costly to have to repeat a surgery because the desirable outcomes might have been undone by smoking,” explained Dr. Preston D. Miller, DDS, and AAP president. “Therefore, it is important patients and doctors agree to a smoking cessation program prior to any periodontal surgery. This will help a patient’s chance of achieving optimal results.”
