Delaying School Start for Adolescents has Positive Impact

Delaying an adolescent’s school start time by one hour has a positive effect on his or her cognitive performance according to a new study. The study, authored by Orna Tzischinsky, PhD, of Emek Yezreel College in Israel, focused on 47 eighth graders from two classes, who were divided into experimental and control groups for a two-week period. On week one, the experimental class began their school day one hour later than usual (at 8:30 a.m.), while the control class began at the regular time (7:30 a.m.). On week two, both classes began at 7:30 a.m. The subjects were asked to maintain their habitual sleep-wake pattern. Actigraphs were worn to monitor sleep-wake patterns. On the fifth day of each week, the students performed a cognitive test. According to the results, during the first week, the experimental class woke up 51 minutes later on average than the control class, while during the second week, the experimental and the control class woke up at the same time. Bedtime and sleep efficiency remained the same during both weeks. “The cognitive tests showed better performance with the experimental group in comparison to the control group on the first week,” said Dr. Tzischinsky. “The results demonstrate […]

Brushing Teeth May Promote Healthy Heart

Each year, cardiovascular disease kills more Americans than cancer. Just brushing and flossing your teeth each day, you might also be avoiding this potentially lethal condition. This is similar study as the one posted yesterday. A new article suggests that periodontal patients whose bodies show evidence of a reaction to the bacteria associated with periodontitis may have an increased risk of developing cardiovascular disease. “Although there have been many studies associating gum disease with heart disease, what we have not known is exactly why this happens and under what circumstances,” said JOP editor Kenneth Kornman, DDS, PhD. “The findings of this new analysis of previously published studies suggest that the long-term effect of chronic periodontitis, such as extended bacterial exposure, may be what ultimately leads to cardiovascular disease.” Researchers at Howard University identified 11 studies that had previously examined clinically-diagnosed periodontal disease and cardiovascular disease. The team then analyzed the participants’ level of systemic bacterial exposure, specifically looking for the presence of the bacteria associated with periodontal disease, as well as measuring various biological indicators of bacterial exposure. They found that individuals with periodontal disease whose biomarkers showed increased bacterial exposure were more likely to develop coronary heart disease or […]

Brush Teeth to Reduce Heart Disease

Heart disease is the #1 cause of death in the world. Even so, numerous people with cardiovascular disease have none of the common risk factors such as smoking, obesity and high cholesterol.  Researchers have now discovered a new link between gum disease and heart disease that may help find ways to save lives. In recent years chronic infections have been associated with a disease that causes “furring” of the arteries, called atherosclerosis, which is the main cause of heart attacks. “A number of theories have been put forward to explain the link between oral infection and heart disease,” said Professor Greg Seymour from the University of Otago Dunedin, New Zealand. “One of these is that certain proteins from bacteria initiate atherosclerosis and help it progress. We wanted to see if this is the case, so we looked at the role of heat shock proteins.” Heat shock proteins are produced by bacteria, animals, and plants. They are produced after cells are exposed to different kinds of stress conditions, such as inflammation, toxins, starvation, oxygen, and water deprivation. They can work as chaperone molecules, stabilizing other proteins, helping to fold them and transport them across cell membranes. Some also bind to foreign […]

Healthy Gums by Cheese, Yogurt, and Milk

Consumers have long known that including dairy in their diets can help maintain healthy bones and even help promote weight loss. However, a recent study published in the January issue of the Journal of Periodontology, the official publication of the American Academy of Periodontology (AAP), demonstrated that routine intake of dairy products may also help promote periodontal health. “Research has suggested that periodontal disease may affect overall systemic health,” said study author Dr. Yoshihiro Shimazaki of Kyushu University in Fukuoka, Japan. “This study reinforces what much of the public already knows – the importance of dairy in helping achieve a healthy lifestyle, including a healthy mouth.” Study participants aged 40 through 79 were examined on two periodontal parameters that can indicate gum disease, periodontal pocket depth (PD) and clinical attachment loss (CAL) of gum tissue. Researchers observed that subjects that consumed 55 or more grams of products containing lactic acid each day had a significantly lower prevalence of deep PD and severe CAL, therefore demonstrating a lower instance of periodontal disease. Periodontal, or gum, disease is a chronic bacterial infection that affects the gums and bone supporting the teeth. Periodontal disease is a major cause of tooth loss in adults […]

World Oral Health Day

Today, September 12th, 2008 has been declared as the First World Oral Health Day. The American Dental Assocation (ADA) and the FDI World Dental Federation want to use the day to “boost awareness of oral health and its impact on general health and well-being.” The date marks the anniversary of the FDI World Dental Federation and their groundbreaking International Conference on Primary Health Care, which was held on September 12, 1978. In addition the date honors Dr. Charles Godon, the FDI founder, who was born Sept. 12, 1854. “We hope that awareness of the importance of oral health can be elevated through the worldwide recognition of this day,” said Dr. Burton Conrod, FDI president. “The dentists of the world are committed to helping each and everyone in achieving optimal oral health through prevention and the highest possible standard of care.” Source: ADA News: ADA, FDI mark first World Health Day
