New National Poll Finds Lack Of Guidance May Delay A Child’s First Dentist Trip

Published

on

Less than half of parents received guidance about starting dental visits from a doctor or dentist, worse among low-income parents.

Without a doctor or dentist’s guidance, some parents don’t follow national recommendations for early dental care for their children, a new national poll finds.

One in 6 parents who did not receive advice from a health care provider believed children should delay dentist visits until age 4 or older – years later than what experts recommend – according to this month’s C.S. Mott Children’s Hospital National Poll on Children’s Health. (link is external)

The American Academy of Pediatrics and the American Dental Association both recommend starting dental visits around age one when baby teeth emerge.

“Visiting the dentist at an early age is an essential part of children’s health care,” says Mott poll co-director Sarah Clark.

“These visits are important for the detection and treatment of early childhood tooth decay and also a valuable opportunity to educate parents on key aspects of oral health.”

“Our poll finds that when parents get clear guidance from their child’s doctor or dentist, they understand the first dental visit should take place at an early age. Without such guidance, some parents turn to family or friends for advice. As recommendations change, they may be hearing outdated information and not getting their kids to the dentist early enough.”

The nationally representative poll is based on responses from 790 parents with at least one child aged 0-5

More than half of parents did not receive guidance from their child’s doctor or a dentist about when to start dentist visits. Among parents who were not prompted by a doctor or dentist, only 35 percent believed dentist visits should start when children are a year or younger as is recommended.

Over half of parents (60 percent) reported their child has had a dental visit with most parents (79 percent) believing the dentist visit was worthwhile.

Among the 40 percent of parents whose child has not had a dental visit, common reasons for not going were that the child is not old enough (42 percent), the child’s teeth are healthy (25 percent), and the child would be scared of the dentist (15 percent).

Experts say starting dental visits early helps set children up for healthy oral hygiene, with parents learning about correct brushing techniques, the importance of limiting sugary drinks, and the need to avoid putting children to bed with a bottle.

Early childhood caries (dental decay in baby teeth) may also be detected at young ages, allowing for treatment of decay to avoid more serious problems. In young children with healthy teeth, dentists may apply fluoride varnish to prevent future decay.

A quarter of parents who had delayed dental visits said their child’s teeth are healthy but Clark notes it is unlikely that a parent could detect early tooth decay.

“Parents may not notice decay until there’s discolouration, and by then the problem has likely become significant,” she says.

“Immediate dental treatment at the first sign of decay can prevent more significant dental problems down the road, which is why having regular dentist visits throughout early childhood is so important.”

Another factor that may delay dental care is that health care recommendations for early childhood are often focused on well-child visits with medical providers, Clark notes.

“Parents hear clear guidelines on when they should begin well-child visits for their child’s health and often schedule the first visit before they even bring their baby home from the hospital. Doctors typically prompt parents to stick to a standard schedule for immunizations and other preventive care,” she says.

“Parents get much less guidance, however, on when to start taking their child to the dentist, with less than half saying they have received professional advice. This lack of guidance may mean many parents delay the start of dental visits past the recommended age.”

Parents with higher income and education and those with private dental insurance were more likely to report that a doctor or dentist provided guidance on when to start dental visits.

“Our poll suggests that families who are low-income, less educated, and on Medicaid are less likely to receive professional guidance on dental care. This is particularly problematic because low-income children have higher rates of early childhood tooth decay and would benefit from early dental care,” Clark says.

“Providers who care for at-risk populations should dedicate time to focus on the importance of dental visits. Parents should also ask their child’s doctor or their own dentist about when to start dentist visits and how to keep their child’s teeth healthy.”

Can These Proteins Cure Cavities?

Published

on

Researchers at the University of Washington have designed a convenient and natural product that uses proteins to rebuild tooth enamel and treat dental cavities.

The research finding was first published in ACS Biomaterials Science and Engineering.

“Remineralization guided by peptides is a healthy alternative to current dental health care,” said lead author Mehmet Sarikaya, professor of materials science and engineering and adjunct professor in the Department of Chemical Engineering and Department of Oral Health Sciences.

The new biogenic dental products can — in theory — rebuild teeth and cure cavities without today’s costly and uncomfortable treatments.

“Peptide-enabled formulations will be simple and would be implemented in over-the-counter or clinical products,” Sarikaya said.

Cavities are more than just a nuisance. According to the World Health Organization, dental cavities affect nearly every age group and they are accompanied by serious health concerns. Additionally, direct and indirect costs of treating dental cavities and related diseases have been a huge economic burden for individuals and health care systems.

“Bacteria metabolize sugar and other fermentable carbohydrates in oral environments and acid, as a by-product, will demineralize the dental enamel,” said co-author Sami Dogan, associate professor in the Department of Restorative Dentistry at the UW School of Dentistry.

Although tooth decay is relatively harmless in its earliest stages, once the cavity progresses through the tooth’s enamel, serious health concerns arise. If left untreated, tooth decay can lead to tooth loss. This can present adverse consequences on the remaining teeth and supporting tissues and on the patient’s general health, including life-threatening conditions.

Good oral hygiene is the best prevention, and over the past half-century, brushing and flossing have reduced significantly the impact of cavities for many Americans. Still, some socio-economic groups suffer disproportionately from this disease, the researchers said. And, according to recent reports from the Centers for Disease Control and Prevention, the prevalence of dental cavities in Americans is again on the rise, suggesting a regression in the progress of combating this disease.

Taking inspiration from the body’s own natural tooth-forming proteins, the UW team has come up with a way to repair the tooth enamel. The researchers accomplished this by capturing the essence of amelogenin — a protein crucial to forming the hard crown enamel — to design amelogenin-derived peptides that biomineralize and are the key active ingredient in the new technology. The bioinspired repair process restores the mineral structure found in native tooth enamel.

“These peptides are proven to bind onto tooth surfaces and recruit calcium and phosphate ions,” said Deniz Yucesoy, a co-author and a doctoral student at the UW.

The peptide-enabled technology allows the deposition of 10 to 50 micrometers of new enamel on the teeth after each use. Once fully developed, the technology can be used in both private and public health settings, in biomimetic toothpaste, gels, solutions and composites as a safe alternative to existing dental procedures and treatments. The technology enables people to rebuild and strengthen tooth enamel on a daily basis as part of a preventive dental care routine. It is expected to be safe for use by adults and children.

Is the Sweet Tooth Gene Connected With Having Less Body Fat?

Published

on

People with a gene variation of FGF21 have a predisposition to less body fat than others, new research conducted at the University of Copenhagen, among others, shows.

It comes as a bit of a surprise to the researchers, who last year discovered that precisely this genetic variation could be one of the reasons why some people have a particular craving for sweet things. People with this variation eat more sugar than others.

‘It sort of contradicts common intuition that people who eat more sugar should have less body fat. But it is important to remember that we are only studying this specific genetic variation and trying to find connections to the rest of the body. This is just a small piece of the puzzle describing the connection between diet and sugar intake and the risk of obesity and diabetes’, says one of the researchers behind the study, Associate Professor Niels Grarup from the Novo Nordisk Foundation Center for Basic Metabolic Research.

Higher Blood Pressure and More ‘Apple Shape’

But the effects associated with the genetic variation are not all positive, the new study shows. The genetic variation is connected with slightly increased blood pressure and more fat around the waist than the hips — that is, more ‘apple shape’.

The study is an international collaboration headed by researchers at the University of Exeter Medical School and has just been published in the scientific journal Cell Reports.

The researchers’ conclusions are based on large amounts of data. They have studied health information from more than 450,000 individuals who have allowed their data to be recorded in the UK Biobank. It includes blood samples, questionnaires on diet and genetic data, among other things.

‘Now that so many people are involved in the study, it gives our conclusions a certain robustness. Even though the difference in the amount of body fat or blood pressure level is only minor depending on whether or not the person has this genetic variation or not, we are very confident that the results are accurate. Around 20 per cent of the European population has this genetic predisposition’, says Niels Grarup.

Potential Drug Target

This new knowledge about people with a ‘genetic sweet tooth’ is mainly important in connection with the development of drugs and future research. Because researchers are currently trying to determine whether it is possible to target or replace FGF21 using drugs in order to treat for obesity and diabetes.

‘Due to its connection with sugar, FGF21 constitutes a potential target in the treatment of for example obesity and diabetes. This research helps us to understand the underlying mechanisms of the hormone and to predict its effects and side effects’, says Niels Grarup.

The study is funded by the European Research Council (ERC), the National Institute of Health (NIH) and the Novo Nordisk Foundation, among others.

Losing Teeth During Middle Age Linked To An Increased Risk Of Cardiovascular Disease

Published

on

Losing two or more teeth in middle age is associated with increased cardiovascular disease risk, according to preliminary research presented at the American Heart Association’s Epidemiology and Prevention | Lifestyle and Cardiometabolic Health Scientific Sessions 2018, a premier global exchange of the latest advances in population-based cardiovascular science for researchers and clinicians.

Studies have shown that dental health problems, such as periodontal disease and tooth loss, are related to inflammation, diabetes, smoking and consuming less healthy diets, according to study author Lu Qi, M.D., Ph.D., professor of epidemiology at Tulane University in New Orleans.

“Previous research has also found that dental health issues are associated with elevated risk of cardiovascular disease,” Qi said.

“However, most of that research looked at cumulative tooth loss over a lifetime, which often includes teeth lost in childhood due to cavities, trauma and orthodontics. Tooth loss in middle age is more likely related to inflammation, but it hasn’t been clear how this later-in-life tooth loss might influence cardiovascular disease risk.”

In a collaborative research effort between Tulane University School of Public Health and Tropical Medicine and Harvard T.H. Chan School of Public Health, Qi and colleagues analyzed the impact of tooth loss in large studies of adults, aged 45 to 69 years, in which participants had reported on the numbers of natural teeth they had, then in a follow-up questionnaire, reported recent tooth loss. Adults in this analysis didn’t have cardiovascular disease when the studies began. The researchers prospectively studied the occurrence of tooth loss during an eight-year period and followed an incidence of cardiovascular disease among people with no tooth loss, one tooth lost and two or more teeth lost over 12-18 years.

They found:

  • Among the adults with 25 to 32 natural teeth at the study’s start, those who lost two or more teeth had a 23 percent increased risk of cardiovascular disease, compared to those with no tooth loss.
  • The increased risk occurred regardless of reported diet quality, physical activity, body weight and other cardiovascular risk factors, such as high blood pressure, high cholesterol and diabetes.
  • There wasn’t a notable increase in cardiovascular disease risk among those who reported losing one tooth during the study period.
  • Cardiovascular disease risk among all the participants (regardless of the number of natural teeth at the study’s start) increased 16 percent among those losing two or more teeth during the study period, compared to those who didn’t lose any teeth.
  • Adults with less than 17 natural teeth, versus 25 to 32, at the study’s start, were 25 percent more likely to have cardiovascular disease.

“In addition to other established associations between dental health and risk of disease, our findings suggest that middle-aged adults who have lost two or more teeth in recent past could be at increased risk for cardiovascular disease,” Qi said.

“That’s regardless of the number of natural teeth a person has as a middle-aged adult, or whether they have traditional risk factors for cardiovascular disease, such as poor diet or high blood pressure.”

Armed with the knowledge that tooth loss in middle age can signal elevated cardiovascular disease risk, adults can take steps to reduce the increased risk early on, he said.

A limitation of the study was that participants self-reported tooth loss, which could lead to misclassification in the study, according to Qi.
