Studies have long associated low-income areas with poor oral health. But dental researchers at Case Western Reserve University and University of Washington sensed that other factors related to income may be at work -- in particular, education level.
So they recently investigated how a parent or other caregiver's education level and dental habits affect children's dental health.
With data from 423 low-income African-American kindergarteners and their caregivers from a CWRU dental school study in 2007, researchers tested the hypothesis that a caregiver's education level influences how often they and their children brush their teeth and visit the dentist for routine checkups, and how those habits result in decayed or filled teeth.
The results supported the hypothesis:
The findings, reported in the Caries Research article, "Caregiver's Education Level and Children Dental Caries in African Americans: A Path Analytic Study," confirm the role of caregiver education in child dental decay and indicate that the caregiver's behavior influences a child's oral health habits.
As a result, researchers hope to encourage parents to become better role models for their children, who pick up on both the positive and negative habits of their caregivers. In the past, improving oral health has focused on educating children about good dental habits. The research team has provided children in the study with dental examinations, tooth sealants, toothbrushes and toothpaste. Children also received lessons on proper care of their teeth.
When dental problems where found during annual exams, letters were sent to parents to tell them their children needed follow-up dental care. But not all caregivers sought help for their children, Heima said.
And nearly 100 of the study's participants -- with or without a high school education -- did not seek routine dental care at least once a year.
So it was the clear the message wasn't getting through.
"Changing their ways with literature and instructions, didn't always work," said Masahiro Heima, a pediatric dentist and faculty member at Case Western Reserve School of Dental Medicine. "So we need to focus on behavioral changes."
