Caregivers Are Key In Protecting Kids’ Dental Health

April_Part 2_Dentistry_Pediatrics

NEW YORK (Reuters Health) – Many kids on Medicaid are not receiving dental care, and those who do often first show up with a dental emergency, according to a new study.

Less than half of a group of four-year-olds the researchers followed had ever visited a dentist, and caregivers who neglected their own oral health tended to neglect that of their children too.

“We know that both good oral health and dental problems tend to cluster and co-occur in families,” said Kimon Divaris, who led the study at the UNC School of Dentistry at the University of North Carolina at Chapel Hill.

According to the American Academy of Pediatric Dentistry, children should visit a dentist for their first check-up when their first tooth appears, or no later than their first birthday. The AAPD recommends check-ups every six months after that to prevent cavities and other problems.

Oral health is part of general health, and dental problems in young children have been linked to other negative consequences including discomfort and pain, reduced quality of life, failure to thrive, time lost both from school and parents’ work and financial expenditures for families and the health system, Divaris told Reuters Health in an email.

Although doctors and dentists have worked to make dental care more accessible for all kids, parents and caregivers play an important role in when and whether kids on Medicaid see a dentist, the authors write in the journal Pediatrics.

“What we are still trying to figure out are the mechanisms that underlie these associations: are they social, economic, cultural, behavioral, genetic or a combination?” Divaris said.

The researchers accessed Medicaid data and caregiver interviews for 1,000 children with no previous dental visits in 2007 and used records to follow the children for two years. On average, kids entering the study were 16 months old.

Over the course of the study, 39 percent of the children saw a dentist for the first time. For more than one in seven of these, that first visit was for a dental emergency.

Kids who had oral health problems as 16-month-olds were more likely to visit a dentist, and were more likely to require emergency care during the study period.

But the analysis did not consider oral health screenings or preventive services provided by pediatricians, which certainly would qualify as improving oral health, said Justin Blackburn of the Department of Health Care Organization and Policy at the University of Alabama at Birmingham School of Public Health.

“We still need more research to understand the benefits of ‘early entry into the dental care system’ as well as barriers to the receipt of oral care,” Blackburn told Reuters Health in an email.

The overwhelming majority of caregivers in this study were female, single and low-income. Kids whose caregivers neglected their own dental health were less likely to see a dentist, the authors wrote.

“Early, preventive visits are aligned with the establishment of a ‘dental home’,” said Divaris, where there’s “an ongoing relationship between the dentist and the patient, and comprehensive oral healthcare is delivered in a continuously accessible, coordinated and family-centered manner.”

Regular visits also help educate parents about oral hygiene, diet, cavity risk and preventive measures like fluoride varnishes, he said.

Because babies’ teeth fall out, parents generally don’t realize they’re important, according to Jane A. Weintraub, dean of the UNC School of Dentistry.

Children develop tooth decay, toothache and infections, much of which is preventable with good dental care, she told Reuters Health in an email.

According to a 2010 U.S. study, 14 percent of three- to five-year-olds had untreated dental decay, including 25 percent of kids living below the poverty level.

Although the new study, and others before it, have found that individual characteristics of caregivers, like how much they care for their own teeth, predict whether or not the child will visit a dentist, there may be larger social forces at work, Divaris said.

There may not be enough dental providers in some communities, or little community support, or there may be an attitude of “dental fatalism,” in which people assume getting cavities as a child is the norm and is accepted, he said.

These barriers can’t easily be addressed, he added, but there are ways to reduce them.

Virtually all children will go to a pediatrician for check-ups and vaccinations, and pediatricians in that setting could perform oral health screenings, educate parents and refer them to dentists, he said.

In some places, school-based programs deliver oral health services without requiring parental involvement, he said.

“Actually, community water fluoridation is a great public health success story along these lines, where a proven measure is delivered in large population segments without relying on individuals’ actions,” he said.

He urged parents and caregivers not to wait for a problem to develop before taking their children to the dentist.

Smokers’ taste buds ‘do not allow them to taste bitterness of coffee’

April_Part 1_Dentistry

Though conventional pairing has cigarettes and coffee going together, researchers have found that the toxic chemicals in tobacco may hamper taste bud regeneration, resulting in smokers not being able to adequately taste the bitterness of their regular cup of joe.

The researchers, led by Nelly Jacob of the Pitié-Salpêtrière Hospital APHP in France, published results of their study in the journal Chemosensory Perception.

They note that tobacco’s chemicals are already known to cause a loss of taste in smokers, as well as structural changes to the fungiform papillae of the tongue – where taste buds are found.

What has been unknown is to what extent smokers’ taste range is affected, whether it returns to normal upon quitting smoking and if so, how long that takes.

Taste buds are largely responsible for conveying sweet, sour, bitter, salty and metallic sensations. According to the Centers for Disease Control and Prevention (CDC), the responsibilities of the taste system include:

  • Triggering digestive systems that change secretions of saliva, stomach acid and pancreatic juices

  • Enhancing feelings of pleasure and satiety when eating

  • Determining quality of foods and determining “good” tasting foods from “bad” ones, which could have potential toxins.

To further investigate the changes in taste buds caused by smoking, Jacob and colleagues tested the ability of 451 study participants to recognize and rate intensity of the four basic tastes – sweet, sour, bitter and salty.

Tobacco product accumulation could impede taste bud regeneration

 

Dividing the participants into three groups (smokers, non-smokers and former smokers), the team conducted the voluntary tests during three separate and consecutive “World No-Tobacco Days.”

A person’s ability to recognize salty, sweet or sour tastes was not influenced by smoking status, the researchers say. However, smoking status did affect their ability to taste the bitterness in caffeine.

While bitter receptors in the tongue are normally able to detect this sensation in even low concentrations, nearly 20% of smokers were not able to correctly identify the taste.

Of the former smokers, 26.5% were not able to identify the taste, while only 13.4% of the non-smokers were unable to correctly identify the bitter samples.

Speaking about their findings, Jacob says:

“We consider that the perception of bitter taste should be examined more closely, both as a tool for smoking cessation or for preventing smoking initiation. More generally, it should be worthwhile to consider the role of chemosensory perceptions in smoking behavior.”

The team believes the accumulation of some tobacco products in the body could impede taste buds regenerating, which could still affect a person’s ability to recognize certain tastes after they have quit smoking.

In the world of taste bud research, Medical News Today recently reported on a digital taste simulator that can produce the four main elements of taste. Researchers say it could one day be used to improve or regenerate sense of taste in cancer patients whose taste buds have been impaired by chemotherapy.
