Effect of Family Income on the Relationship Between Parental Education and Sealant Prevalence, National Health and Nutrition Examination Survey, 2005-2010

Sealant Utilization and its Influence on Caries Reduction in First Permanent Molars in Saudi Female School Children

Purpose:

This study aimed to assess the utilization of fissure sealants and their influence on caries reduction in first permanent molars (FPMs) among 6-9 years old female schoolchildren in Dammam, Eastern Province of Saudi Arabia.

Materials and Methods:

First to fourth grade female children from public schools in Dammam participated in this cross-sectional study. Dental caries and fissure sealants in FPMs were examined clinically using the World Health Organization guidelines. In addition, the parents of the participants responded to a self-reported questionnaire.

Results:

The study analyzed the data of 449 children. Almost 44.3% of the participants had at least one FPM affected with caries. There were 8.7% of the participants who had fissure sealants in at least one FPM, and out of these, only 2.2% had four FPMs filled with sealants. A significantly greater proportion of participants with sealed FPMs had no caries than the lower proportion of participants without sealants who had caries (P=<0.05). The use of sealants increased significantly from first grade (10.3%) to second grade (30.8%), third grade (38.5%), and fourth grade (20.5%) (P=0.006). High monthly family income (P= 0.047) and having insurance (P=0.017) were significantly associated with increased sealant application. Nearly 21.9% of participants’ parents were aware of caries protective effects of dental sealants.

Conclusion:

The application of sealants was significantly associated with reduced caries in FPMs. Class year, monthly family income, and insurance were significantly associated with having sealants. Caries prevention programs for children should incorporate sealant application.

Changes in oral health indicators due to implementation of the National Health Insurance Services coverage for first molar dental sealant for children and adolescents in South Korea

Background

In South Korea, dental sealant was included in the National Health Insurance Services (NHIS) coverage for the first molar for ages 6–14 in December 2009. The second molar was included in 2012, and the age of insurance coverage was extended to under 18 in 2013. This study aimed to verify the effectiveness of an NHIS dental sealant coverage policy for children and adolescents by comparing the changes in first molar oral health indicators before and after policy implementation.

Methods

The Korea National Health and Nutrition Examination Survey data were analyzed; the fourth period (2007–2009) provided data for before and the sixth period (2013–2015) provided data for after policy implementation. The proportion of individuals with first-molar sealant, decay-missing-filled first molar permanent teeth, and single crowns in the group aged 11–20 years were calculated. Data were analyzed using chi-square for complex samples and the complex samples general linear model. In addition, complex-sample logistic regression analysis was performed to confirm the association between factors.

Results: Compared with non-beneficiaries, among policy beneficiaries, sealant ownership increased by 7.7% (from 27.8 to 35.5, P < 0.001), and the number of permanent teeth with sealant per capita increased by approximately 0.4 to 0.8 (P < 0.001). The proportion of individuals with decay-missing-filled permanent teeth decreased by 9.1% (from 68.4 to 59.3, P < 0.001), and the average decay-missing-filled permanent teeth index per person decreased by approximately 2.0 to 1.5 (P < 0.001). The rate of single-crown holders decreased by 2.7% (from 8.7 to 6.0, P > 0.05), and the average single-crown index decreased by approximately 0.11 to 0.08 per person(P > 0.05). The number of sealants increased with age and household income (P < 0.001). The mother’s education level affected sealant experience (P < 0.05). The caries rate was higher in females and older respondents (P < 0.001).

Conclusions

The sealant covered by NHIS contributed to decreasing dental caries in Korea. However, policies that can reduce oral health inequality should also be considered, and a follow-up study is required for long-term sealant maintenance in Korea.

Are parents' education levels associated with either their oral health knowledge or their children's oral health behaviors? A survey of 8446 families in Wuhan

Background

Children aged 6–7 years are in the early mixed dentition, which is a period of high prevalence of dental caries and other dental diseases and a critical period for the formation of oral health behaviors. Therefore, good oral hygiene habits of children and oral health knowledge of parents are very important. This study sought to explore the relationship between children’s oral health behaviors, parental oral health knowledge, parental choices of pit and fissure sealants, and parents’ education levels based on a large-scale sample size for the first time, and to compare the influences of parental education levels between parents.

Methods

Families of the first and second graders of primary schools in Wuhan Hongshan District were included in this study. A total of 8446 questionnaires were collected to obtain comprehensive information on children’s oral health behaviors, parents’ oral health knowledge and parents’ pit and fissure sealants-related choices. The relationship between these outcome variables and parents’ education levels were studied using logistic regression analysis and chi-square test.

Results

Parents who reported good educational background had more favorable oral health knowledge than those of other parents, and their children had better oral hygiene behaviors. Four indicators of five measures to children’s oral health behaviors were significantly associated with mother’s education level (P < 0.05), and three of them were related to father’s education level (P ≤ 0.01). Moreover, seven indicators of eight measures to parents’ oral health knowledge were significantly related to mother’s education level (P < 0.05) and four of them were affected by the father’s (P < 0.05). In addition, parents with higher educational attainments paid more attention to the completeness of medical facilities, the environment of dental practice, the distance to treatment sites, and took less concern of children’s willingness when choosing the pit and fissure sealants sites.

Conclusions

In families with children at the early mixed dentition stage, parents with higher education levels tend to have better oral health knowledge and more oral health care needs, such as pit and fissure sealants. In addition, children of parents who have better educated parents tend to perform better oral hygiene practices.

Households' age, country of birth, and marital status, stronger predictor variables than education in the prevalence of dental sealants, restorations, and caries among US children 5-19 years of age, NHANES 2005-2010

Background

The aim of this study is to use data representative of the U.S. population to determine if households (HHs) age, birth country, and marital status, are strong predictors as HHs education for dental sealants, restorations, and caries in children 5 to 19 years of age.

Methods

A cross sectional analysis was performed with oral health data from three waves of the National Health and Nutrition Examination Survey (NHANES 2005 to 2010). The sample size consisted of children 5 to 19 years of age (n = 9151) and households > 18 years of age (n = 31,034). Dependent variables included the number of children with dental sealants, restorations, and caries. HHs independent variables consisted of gender, age, race, country of birth, HHs education level, marital status, and HHs spouse education. Multivariate regression analysis models were adjusted for HHs citizenship, health insurance, family size, and children age categories.

Results

The prevalence of children 5–19 years of age with dental sealants, restorations, and caries was 31.3, 43, and 15.8% respectively. The odds of children having sealants were higher among HHs with a college education or above OR 2.05 [1.54.-2.73] vs. HHs with a < 9th grade, in HHs ages 39–49 (OR 1.78 [1.41–2.24) vs. 18–29 years of age, and in HHs spouses with a college education and above OR 1.71 [1.14–2.56] vs. HHs with a < 9th grade. The odds of having at least one restored tooth were higher in children from HHs born in Mexico 1.74 [1.44–2.10] vs. US born. The highest odds for caries were among children from HHs that were never married 1.91 [1.47–2.48] vs. married HHs. In HHs with a college education the odds for caries in children were 0.31 (0.22–0.43) for college and above, and 0.78 (0.60–1.01) for some college.

Conclusions

The odds of children having dental sealants were higher in HHs with a college education, however, HHs ages 30–49 provided higher odds for sealants than spouses with college education. HHs birth place increased the odds of children with restorations more than HHs education. Children from HHs that never married had higher odds of experiencing dental caries. Recognizing the impact of these HHs characteristics could augment efforts in the prevention of adverse oral health outcomes in U.S. children.

Households’ age, country of birth, and marital status, stronger predictor variables than education in the prevalence of dental sealants, restorations, and caries among US children 5–19 years of age, NHANES 2005–2010.

Awareness Among US Adults of Dental Sealants for Caries Prevention

INTRODUCTION

Dental sealants applied in childhood can help prevent caries, but knowledge of the availability of sealants and their function is not widespread. We assessed knowledge of dental sealants among US adults and adult parents of children younger than 18 and the differences in knowledge among demographic and socioeconomic groups.

METHODS

We used data on 3,550 respondents to the 2015 FallStyles B survey of noninstitutionalized US adults aged 18 or older. Authors constructed estimates by using weights provided to reflect the distribution of the US population. Knowledge of dental sealants was assessed by sex, age, race/ethnicity, education, household income, and parental status. Multivariate analysis was conducted by using a main effects logistic regression model.

RESULTS

Overall, 46.3% of adults and 55.1% of parents of children younger than 18 had knowledge of dental sealants. Sealant knowledge was highest among parents, women, respondents aged 45 to 59, and respondents with incomes greater than 200% of the federal poverty level and more than a high school education. Non-Hispanic blacks had less than half the odds of non-Hispanic whites of having knowledge of sealants (adjusted odds ratio [OR] = 0.4), and nonparents had half the odds as parents (OR = 0.5) of knowing. The strongest predictors of parental sealant knowledge were race/ethnicity, sex, and income.

CONCLUSION

Disparities in sealant knowledge correspond to disparities in sealant prevalence. Increasing knowledge among low-income and racial/ethnic minority parents could reduce disparities in sealant prevalence and untreated caries.

School-Based Dental Sealant Programs Prevent Cavities And Are Cost-Effective

Untreated cavities can have far-reaching negative consequences for people's ability to eat, speak, and learn. By adolescence, 27 percent of low-income children in the United States will have untreated cavities. School-based sealant programs typically provide dental sealants (a protective coating that adheres to the surface of molars) at little or no cost to students attending schools in areas with low socioeconomic status. These programs have been shown to increase the number of students receiving sealants and to prevent cavities. We analyzed the cost-effectiveness of school sealant programs using data (from school programs in fourteen states between 2013 and 2014) on children's cavity risk, including the effects of untreated cavities on a child's quality of life. We found that providing sealants in school programs to 1,000 children would prevent 485 fillings and 1.59 disability-adjusted life-years. School-based sealant programs saved society money and remained cost-effective across a wide range of reasonable values.
