Socioeconomic inequalities in oral health in childhood and adulthood in a birth cohort

Effectiveness evaluation of Contra Caries Oral Health Education Program for improving Spanish-speaking parents' preventive oral health knowledge and behaviors for their young children

OBJECTIVES

To determine the effectiveness of the Contra Caries Oral Health Education Program (CCOHEP) for improving low-income, Spanish-speaking parents' oral health knowledge and behaviors for their young children. Mexican American children in the United States suffer disproportionately high prevalence and severity of early childhood caries, yet few evaluated, theory-based behavioral interventions exist for this population. CCOHEP is a theory-based curriculum consisting of four 2-h interactive classes designed for and by Spanish speakers and led by designated community health educators (promotoras). Topics included children's oral hygiene, caries etiology, dental procedures, nutrition, child behavior management, and parent skill-building activities.

METHODS

Low-income Spanish-speaking parents/caregivers of children aged 0-5 years were recruited through community services in an agricultural city in California. Survey questions from the Oral Health Basic Research Facts Questionnaire measuring oral health-related behaviors and knowledge were verbally administered before, immediately after, and 3 months after attendance at CCOHEP. Five questions measured aspects of parental toothbrushing for their children (frequency, using fluoridated toothpaste, brushing before bed, not drinking or eating after nighttime brushing, adult assistance), three questions measured other oral health behaviors, and 16 questions measured oral health-related knowledge. Analyses of within-person changes between pre- and post-tests and again between post-test and 3-month follow-up consisted of McNemar's test for binary outcomes and sign tests for ordinal outcomes.

RESULTS

Overall, 105 caregivers participated in CCOHEP (n = 105 pretest, n = 95 post-test, n = 79 second post-test). At baseline, all parents self-reported doing at least one aspect of toothbrushing correctly, but only 13% reported performing all five aspects according to professional guidelines. At post-test, 44% of parents reported completing all aspects of toothbrushing according to professional guidelines (P < .001). Statistically significant improvements were seen in 4 aspects of toothbrushing (P ≤ .008) between pretest and post-test (all but adult assistance). The second post-test showed 3 of these improvements were maintained, while adult assistance and the other reported behaviors improved (P ≤ .008). Between pretest and post-test, checking child's teeth monthly and frequency of sweet drinks consumption improved (P ≤ .008), while frequency of eating sweet foods did not change. Knowledge was high at baseline (mean 12.8 of 16), but 6 knowledge items improved significantly between pretest and post-test. Improvements were maintained at second post-test.

CONCLUSIONS

Contra Caries Oral Health Education Program improved low-income Spanish-speaking parents' oral hygiene knowledge and self-reported behaviors for their young children, and change was sustained 3 months after the end of the intervention. Future, more rigorous evaluation of the intervention is recommended.

The Association Between Income Inequality and Oral Health in Canada

Societies exhibiting higher levels of economic inequality experience poorer health outcomes, and the proposed pathways used to explain these patterns are also relevant to oral health. This study therefore examines the relationship between the level of income inequality and the oral health and dental care services utilization of residents from eleven Canadian metropolitan areas. We calculated Pearson correlation coefficients (r) between each metropolitan area's Gini coefficient (used as a proxy for income inequality, calculated from 2006 Canadian census data) and each area's experience of dental pain, self-reported oral health, and use of dental care services (provided by data from the 2003 Canadian Community Health Survey). Greater levels of income inequality in the selected metropolitan areas were related to an increased likelihood of residents self-reporting their oral health as poor/fair and reporting a prolonged absence from visiting a dentist. There was, however, no relationship between the level of income inequality and the likelihood of respondents reporting a recent toothache, tooth sensitivity, or jaw pain. Policies designed to improve the oral health of the population, and Canadians' access to dental care generally, may therefore work best when supported by policies that promote greater economic equality within Canada.

[Adult tooth loss profile in accordance with social capital and demographic and socioeconomic characteristics]

Demographic and socioeconomic conditions play an important role in tooth loss in the population, however, there is little scientific evidence regarding the influence of social capital on this outcome. The scope of this study was to describe the tooth loss profile of adults aged 35-44, who are residents of the surrounding area of the city of Belo Horizonte in the state of Minas Gerais. This cross-sectional exploratory study comprised a sample of 1,013 adults. The dependent variable was tooth loss. Exploratory variables were social capital, demographic and socioeconomic characteristics. The Chi-squared Automatic Interaction Detector (CHAID) was used to map the adult tooth loss profile which was explained by low levels of social capital (47.0%; p < 0.001), more elderly adults (60.2%; p < 0.001), and low education levels (66.3%; p = 0.022). In the high social capital group, age was the determinant factor of tooth loss, irrespective of educational level or per capita income. The conclusion, at the individual level, is that social capital as well as demographic and socio economic characteristics explained the adult tooth loss profile. Individual social capital may have attenuated the negative influence of socioeconomic factors in the population under scrutiny.

Longevity of direct restorations in Dutch dental practices. Descriptive study out of a practice based research network

OBJECTIVES

The aim of this retrospective practice-based study was to investigate the longevity of direct restorations placed by a group of general dental practitioners (GDPs) and to explore the effect of practice/operator, patient, and tooth/restoration related factors on restoration survival.

METHODS

Electronic Patient Files of 24 general dental practices were used for collecting the data for this study. From the patient files, longevity of 359,548 composite, amalgam, glass-ionomer and compomer placed in 75,556 patients by 67 GDPs between 1996 and 2011 were analyzed. Survival was calculated from Kaplan-Meier statistics.

RESULTS

A wide variation in annual failure rate (AFR) exists between the different dental practices varying between 2.3% and 7.9%. Restorations in elderly people (65 years and older, AFR 6.9%) showed a shorter survival compared to restorations placed in patients younger than 65 years old (AFR 4.2%-5.0%). Restorations in molar teeth, multi-surface restorations and restorations placed in endodontically treated teeth seemed to be more at risk for re-intervention.

CONCLUSION

The investigated group of GDPs place restorations with a satisfactory longevity (mean AFR 4.6% over 10 years), although substantial differences in outcome between practitioners exist. Several potential risk factors on practice/operator, patient, and tooth/restoration level have been identified and require further multivariate investigation.

An assessment of dental caries among young Aboriginal children in New South Wales, Australia: a cross-sectional study

BACKGROUND

Limited research has been undertaken in Australia to assess the dental status of pre-school Aboriginal children. This cross-sectional study records the number of decayed, missing and filled teeth (dmft) and surfaces (dmfs) of pre-school Aboriginal children living in different locations in New South Wales (NSW), Australia.

METHODS

A convenience sample of young children from seven Aboriginal communities in rural, remote and metropolitan areas of NSW, was recruited. One calibrated examiner recorded the dmft/s of children with written parental consent.

RESULTS

196 children were invited to participate and 173 children aged two to five years were examined, a response rate of 88.3%. Forty percent (n = 69) of the children were diagnosed with dental caries with a mean of 2.1 (SD = 3.6). The dmft scores were significantly higher in remote locations when compared to rural (p = <0.0001) and metropolitan areas (p = 0.0155). Children 4-5 years old living in remote NSW had a mean dmft of 3.5 and mean dmfs of 8.0 compared with children living in rural areas who had a dmft and dmfs of 1.5 and 4.2 respectively. Untreated dental caries was the primary contributor to the scores, and children who had previously received dental treatment still had active carious lesions.

CONCLUSION

There was a high prevalence of untreated dental caries among the Aboriginal children, particularly for those in remote locations.

Social position, social ties and adult's oral health: 13 year cohort study

OBJECTIVES

This study explored different pathways by which social position and social ties influence adult's oral health over a 13-year period.

METHODS

A cohort investigation (Pro-Saúde Study) was conducted of non-faculty civil servants at a university in Rio de Janeiro, Brazil (N=1613). Baseline data collected in 1999 included age, social position, social ties, and access to dental care. Psychological factors and smoking were assessed in 2001, whereas tooth loss and self-rated oral health (SROH) were collected in 2012. A hypothesised model exploring different direct and indirect pathways was developed and tested using structural equation modelling.

RESULTS

The model was a good fit to the data and accounted for 40% and 27% of the variance in tooth loss and SROH, respectively. A greater social position was linked to more social ties (β=0.31), health insurance (β=0.48), low psychological distress (β=0.07), less smoking (β=-0.21), more regular dental visiting (β=0.30), less tooth loss (β=-0.44) and better SROH (β=-0.25) over time. Social position (β=0.0005) and social ties (β=-0.0015) were linked indirectly with psychological distress, smoking and tooth loss. Social position was linked indirectly with social ties, psychological distress and SROH (β=-0.0071).

CONCLUSIONS

Poor social position and weak social ties were important predictors for tooth loss and poor SROH in adults over the 13-year period. Direct and indirect pathways via psychological factors and smoking on the aforementioned relationships were identified, suggesting different areas of intervention to promote adults' oral health.

CLINICAL SIGNIFICANCE

Adult's oral health is influenced by social conditions through direct and indirect pathways, including via psychological factors and smoking.

The Relationship Between Life Course Factors, Parental Demographics, Dental Coping Beliefs and Its Influence on Adolescents Dental Visit: a Cross Sectional Study

Background

Oral Disease is a multifactorial one that includes behavioral and cultural components, and the severity of the disease depends on regularity of dental visits. The purpose of the study was to evaluate the relationship between parental demographics, life course factors, dental coping beliefs with therecent dental attendance among adolescents in Udupi Taluk.

Methods

Three hundred and fifty adolescents aged 16–19 years from four randomly selected schools in Udupi Taluk participated in this cross sectional study. Information was obtained regarding their parental demographics, their early life course, dental coping beliefs and recent dental attendance. Bivariate followed by multiple logistic regression analysis was performed to elicit variables which predict recent dental attendance.

Results

Out of the 324 adolescents who completed the questionnaire, 25.3% reported visiting a dentist within a period of one year. Childhood dental visit, childhood dental experience, housing, internal and external locus of control and self-efficacy were significantly associated with recent dental visit (p<0.05). Participants who lived in cement/brick houses were 4.3 times more likely to visit a dentist within one year compared to those living in hut/mud/combined houses (p<0.05). Adolescents with lower external (OR= 0.11, P<0.003) and low internal (OR=0.05, P<0.001) locus of control had lower odds of visiting a dentist within a year when compared with those having higher locus of control.

Conclusion

Childhood financial hardships, childhood dental visits and experiences and dental coping beliefs affect dental attendance pattern during adolescence. These factors should be considered while tailoring interventions to promote the oral health and dental attendance behaviors of adolescents.

Epidemiological investigation of caries prevalence in first grade school children in Rhineland-Palatinate, Germany

Introduction

The annual examination of first graders’ oral health as stipulated by law aimed to reach every child in Rhineland-Palatinate (Germany) in their first year of school. We intended to evaluate the first graders’ oral health based on the examination data for 2013/2014.

Methods

Instructed examiners measured the d3mft(deciduous)/D3MFT(permanent) index according to World Health Organization criteria in 25,020 predominantly 6–7 year-old first-grade school children. Only caries affecting dentin was diagnosed; no radiography or fiber-transillumination was used. Out of the d3mft value, the “Significant Caries Index” (SiC) was calculated. This index identifies the dmft score of the third of the population with the highest caries experience. Descriptive analysis was performed.

Results

Out of the the examined children, 60.9 % were caries free. Mean d3mft score was 1.28 ± 2.27 while the mean SiC was 3.73 ± 2.51. A distinctly higher d3mft was found in the decidous molars compared to the front teeth. Boys were significantly more caries-experienced than girls (p < 0.001).

Conclusion

The results of this study confirm the lasting trend towards decreasing caries prevalence in children starting school found in previous cross-sectional studies. This trend was observed in the high-risk group (obtained by SiC) as well as in the entire study population. Particular attention in caries prophylaxis should be paid to the primary molars.

Permanent dentition caries through the first half of life

AIM

To describe the occurrence of dental caries at the person, tooth and tooth surface level from childhood to early mid-life.

BACKGROUND

No studies have reported on age and caries experience in a population-based sample through the first half of life.

METHODS

Prospective cohort study of a complete birth cohort (n = 1,037) born in 1972/73 in Dunedin, New Zealand. Dental examinations were conducted at ages 5, 9, 15, 18, 26, 32 and 38, and participation rates remained high. Surface-level caries data were collected at each age (WHO basic methods). Statistical analyses and graphing of data were undertaken using Intercooled Stata Version 10.

RESULTS

Data are presented on dental caries experience in the permanent dentition at ages 9, 15, 18, 26, 32 and 38. Percentile curves are charted and reported for person-level caries experience. Data are also presented on the number of decayed teeth and tooth surfaces, (including root surfaces at age 38), as a function of the number of teeth and surfaces present, respectively. Across the cohort, the number of tooth surfaces affected by dental caries increased by approximately 0.8 surfaces per year (on average), while the percentage of at-risk tooth surfaces affected by caries increased by approximately 0.5% per year, with negligible variation in that rate throughout the observation period.

CONCLUSION

These unique data show clearly that dental caries continues as a disease of adulthood, remaining important beyond childhood and adolescence and that rates of dental caries over time remain relatively constant.

The Association between Participation of Adolescents in Community Groups and Dental Caries in a Deprived Area in Brazil

There is limited evidence concerning the role of social networks on the oral health of adolescents. This study assessed the association between the participation of adolescents in community groups and dental caries. A cross-sectional household-based study was carried out involving 200 subjects aged 15-19 years living in a deprived area in the state of Amazon, Brazil. Dental caries was assessed through dental examinations using the DMFT index conducted by a single examiner who was previously calibrated. Four dental caries outcomes were investigated, including caries experience (DMFT score), current caries (number of current decayed teeth), missing teeth due to caries, and the care index (ratio between number of filled teeth and DMFT score). Details of participation of adolescents in community groups, demographic and socioeconomic data and information on dental visiting were obtained through individual interviews. All caries measures were significantly higher in adolescents who did not participate in community groups compared to their counterparts. Multivariate Poisson regression showed that participation of adolescents in community groups was independently associated with all dental caries outcomes. After adjusting for confounders, participation in community groups was statistically associated with lower DMFT score (ratio of mean, RM: 0.33, 95% CI: 0.24-0.46), fewer decayed teeth (RM: 0.23, 95% CI: 0.11-0.47), fewer missing teeth (RM: 0.28, 95% CI: 0.17-0.47), and higher care index (RM: 1.69, 95% CI: 1.24-2.29) than those who did not participate. Participation of adolescents in community activities was related to lower levels of dental caries.

Association of parental education with tooth loss among Korean Elders

OBJECTIVE

There are few reports showing an association between childhood socioeconomic circumstances and tooth loss among the elderly. The purpose of this study was (i) to examine the association between early childhood socioeconomic position (parental education level) and tooth loss and (ii) to determine the relative effects of the subjects' education level, occupation, and income on tooth loss in Korean elders.

MATERIAL AND METHODS

Data from the fourth and fifth Korea National Health and Nutritional Examination Survey on 8814 Korean elders (age ≥65 years) were analyzed. Demographic factors (age, survey year, marital status, and residence area), health behaviors (dental check-up during the past year and cigarette smoking), and the presence of a somatic health problem (diabetes) were included in our gender-specific analyses. Tooth loss was defined as edentulism or severe tooth loss (<20 teeth). For our analyses, chi-square test and Student's t-tests and multiple logistic regressions were performed.

RESULTS

A low parental education level was associated with elevated odds of edentulism (OR = 1.87 for father's education and 1.52 for mother's education among male elders and OR = 1.73 for father's education and 1.55 for mother's education among female elders) and with severe tooth loss (OR = 1.58 for father's education and 1.53 for mother's education among male elders and OR = 1.25 for father's education and 1.48 for mother's education among female elders). The association between parental education level and tooth loss was attenuated after adjusting for the subject's education level, occupation, and income. Relative magnitude of attenuation varied with personal factors (education > income > occupation). In a fully adjusted model, father's education level was significantly associated with edentate status (OR = 1.96 for male elders and 1.46 for female elders), but not with severe tooth loss.

CONCLUSION

Our results indicate that early life socioeconomic circumstances measured by the father's education level were independently associated with the edentate status of Korean elders.

Life course experiences and lay diagnosis explain low-income parents' child dental decisions: a qualitative study

OBJECTIVE

This study aimed to better understand low-income parents' child dental care decisions through a life course approach that captured parents' experiences within the social context of poverty.

METHODS

We conducted 43 qualitative life history interviews with 10 parents, who were long-term social assistance recipients living in Montreal, Canada. Thematic analysis involved interview debriefing, transcript coding, theme identification and data interpretation.

RESULTS

Our interviews identified two emergent themes: lay diagnosis and parental oral health management. Parents described a process of 'lay diagnosis' that consisted of examining their children's teeth and interpreting their children's oral signs and symptoms based on their observations. These lay diagnoses were also shaped by their own dental crises, care experiences and oral health knowledge gained across a life course of poverty and dental disadvantage. Parents' management strategies included monitoring and managing their children's oral health themselves or by seeking professional recourse. Parents' management strategies were influenced both by their lay diagnoses and their perceived ability to manage their children's oral health. Parents felt responsible for their children's dental care, empowered to manage their oral health and sometimes forgo dental visits for their children because of their own self-management life history.

CONCLUSION

This original approach revealed insights that help to understand why low-income parents may underutilize free dental services. Further research should consider how dental programs can nurture parental empowerment and capitalize on parents' perceived ability to diagnose and manage their children's oral health.

Tough luck and tough choices: applying luck egalitarianism to oral health

Luck egalitarianism is often taken to task for its alleged harsh implications. For example, it may seem to imply a policy of nonassistance toward uninsured reckless drivers who suffer injuries. Luck egalitarians respond to such objections partly by pointing to a number of factors pertaining to the cases being debated, which suggests that their stance is less inattentive to the plight of the victims than it might seem at first. However, the strategy leaves some cases in which the attribution of individual responsibility is appropriate (and so, it seems, is asking people to pick up the tab for their choices). One such case is oral health or significant aspects of this. It is appropriate, the paper argues, to hold people responsible for a number of factors that affect their oral health. A luck egalitarian approach inspired by John Roemer can assess whether people have acted responsibly by comparing their choices to those of their peers. A luck egalitarian approach to oral health would recommend prioritizing scarce resources in a responsibility-weighted queuing system and include copayment and general taxation among its measures of financing.

Education-related Inequity in Access and Utilization of Oral Health Care in Iran

Background:

Oral health affects peoples’ lives physically and psychologically and is related to general health, quality of life, and feelings of social well-being. As the educational level is an important predictor of healthy life and can affect healthcare utilization, this study aims to estimate the inequity related to the educational level of parents on the access and utilization of oral health care (OHC) in Qom, Iran. Study Design: An analytical, cross-sectional study.

Materials and Methods:

Overall 281 children, six to seven years of age, were given a self-administrated questionnaire to fill. The sex, access to utilization of OHC, and educational level of the children's parents were questioned. The concentration (C) index was used as the inequity measure and statistical inference was conducted by chi square and the confidence interval of C.

Statistics:

The mean age of the children was 6.48 ± 0.5 years. There was not statistically significant difference in the access and utilization rate of OHC between the two sexes (P > 0.05). There was an increasing trend in the utilization rate of OHC, because of the increased educational level of the parents. The C for access and utilization rate, for different levels of fathers’ education was 0.055(-0.095 to 0.205) and 0.097(-0.068 to 0.261) and for mothers’ educational level was 0.086(-0.068 to 0.241) and 0.091(-0.81 to 0.263), respectively.

Conclusion:

Our results did not show evidence of sex disparity in the access and utilization of OHC in Iranian children. Also the inequity related to the educational level in access and utilization of OHC was low and not considerable.

Which life course model better explains the association between socioeconomic position and periodontal health?

AIM

To assess whether the relationship between socioeconomic position (SEP) and periodontal health fitted the Critical Period or the Social Mobility life course models.

METHODS

A nationally representative sample of 5570 Korean adults from KNHANES IV study. Log-binomial regression models adjusting for adulthood or childhood socioeconomic (SES) variables was used to assess independent effects of socioeconomic differences for childhood, adulthood and period of transition from child to adult in periodontal health.

RESULTS

In the Critical Period model, poorer periodontal status was associated with SES disadvantage in adulthood and not predicted by SES disadvantage in childhood. For the intergenerational Social Mobility model, prevalence of current periodontal disease was only different for females aged 30-39 and 40-49 years, after adjustment. Prevalence of periodontal disease in females was highest in the downwardly mobile group.

CONCLUSIONS

The Critical Period model was better at explaining association between socioeconomic position and periodontal health, such as the adulthood socioeconomic variables (SEP), had a stronger effect than childhood factors on periodontal disease. The Social Mobility model explained more of the variation in the association between SEP and periodontal health among women than among men.

Intergenerational mobility and adult oral health in a British cohort

OBJECTIVES

This study aimed to characterize trajectories of intergeneration mobility from birth to age 33 years and to assess the influence of these trajectories on adult oral health.

METHODS

Repeated data on occupational social class (birth and 7, 11, 16, 23 and 33 years) and two subjective oral health indicators (lifetime and past-year prevalence of persistent trouble with gums or mouth) measured at age 33 years, from the 1958 National Child Development Study, were used for this analysis. Latent class growth analysis (LCGA) was used to identify different trajectories of exposure to manual social class over time. Binary logistic regression was then used to explore the association between these trajectories and each oral health indicator, adjusting for participants' sex.

RESULTS

Latent class growth analysis showed that a four trajectory model provided the best fit to the data. The four trajectories that emerged were identified as stable manual, stable nonmanual, late steep increase (those who were likely to be in the manual social class until age 16 years but ended up in the nonmanual social class afterwards) and steady increase (those whose likelihood of leaving the manual social class increased gradually over time). Lifetime and past-year prevalence of persistent trouble with gums or mouth was significantly higher in the stable manual trajectory than in all other trajectories. No differences were found between the stable nonmanual, late steep increase and steady increase trajectories.

CONCLUSION

Although four distinctive trajectories were identified in the 1958 NCDS, only those who remained in the manual social class over time reported worse oral health by age 33 years. Proximal socioeconomic experiences may be more relevant to adult oral health than early life experiences.

Time trends in socio-economic inequalities in the lack of access to dental services among children in Spain 1987-2011

INTRODUCTION

Adult oral health is predicted by oral health in childhood. Prevention improves oral health in childhood and, consequently in adulthood, so substantial cost savings can be derived from prevention. The burden of oral disease is particularly high for disadvantaged and poor population groups in both developing and developed countries. Therefore, an appropriate and egalitarian access to dental care becomes a desirable objective if children's dental health is to be promoted irrespective of socioeconomic status. The aim of this research is to analyse inequalities in the lack of access to dental care services for children in the Spanish National Health System by socio-economic group over the period 1987-2011.

METHODS

Pooled data from eight editions of the Spanish National Health Survey for the years 1987-2011, as well as contextual data on state dental programmes are used. Logistic regressions are used to examine the related factors to the probability of not having ever visited the dentist among children between 6 and 14 years old. Our lack of access variable pays particular attention to the socioeconomic level of children's household.

RESULTS

The mean probability of having never been to the dentist falls considerably from 49.5% in 1987 to 8.4% in 2011. Analysis by socioeconomic level indicates that, in 1987, the probability of not having ever gone to the dentist is more than two times higher for children in the unskilled manual social class than for those in the upper non-manual social class (odds ratio 2.35). And this difference is not reduced significantly throughout the period analysed, rather it increases as in 1993 (odds of 2.39) and 2006 (odds of 3.03) to end in 2011 slightly below than in 1987 (odds ratio 1.80).

CONCLUSION

There has been a reduction in children's lack of access to dentists in Spain over the period 1987-2011. However, this reduction has not corrected the socioeconomic inequalities in children's access to dentists in Spain.

Survival characteristics of composite restorations in primary teeth

OBJECTIVES

This retrospective study analyzed restoration survival of composite fillings in children with at high caries risk in relation to age, sex, operator, tooth type, filling extension, and material used.

MATERIALS AND METHODS

Among 667 children treated in 2004-2012 in a university setting without sedation or general anesthesia, 2388 composite fillings were included. Relevant data from regular recall intervals were retrieved from patients' records. Either total-etch or a self-etch adhesive combined with flowable and/or (nano)hybrid composite was used. The Kaplan-Meier estimator and Cox proportional hazard analysis with backward elimination model were applied for survival analysis.

RESULTS

For the observation period of 8 years (mean 1.7 years), the cumulative failure rate was 17.2 % with annual failure rates of 10.0 %. In 8.8 % of the cases, fillings failed due to secondary caries. In 8.3 % technical failure due to total filling loss, loosening, marginal gaps, or tooth fracture occurred. Tooth type, filling extension, age, operator, dental dam, and type of adhesive were significant for survival (p < 0.05).

CONCLUSIONS

Filling survival was comparably lower to composite restorations observed in prospective clinical studies on permanent teeth and other tooth-colored restoratives used in primary teeth. Due to the very high caries risk and young age of the population, frequent loss due to secondary caries was observed. With respect to the high caries risk, composite restorations can be used to treat carious primary teeth, though a strict caries prevention regimen should be followed to minimize restoration failure.

CLINICAL RELEVANCE

Filling loss of composites in the primary dentition is associated with secondary caries on the long term.

Early life-course socioeconomic position, adult work-related factors and oral health disparities: cross-sectional analysis of the J-SHINE study

OBJECTIVES

We examined the association between socioeconomic position (SEP) and oral health, and the associations of economic difficulties in childhood and workplace-related factors on these parameters.

DESIGN

Cross-sectional study.

PARTICIPANTS

A total of 3201 workers aged 25-50 years, living in and around Tokyo, Japan, from the J-SHINE (Japanese study of Stratification, Health, Income, and Neighborhood) study. The response rate was 31.6%.

OUTCOME MEASURES

Self-rated oral health (SROH)-A logistic regression model was used to estimate ORs for the association between poor SROH and each indicator of SEP (annual household income, wealth, educational attainment, occupation and economic situation in childhood). Multiple imputation was used to address missing values.

RESULTS

Each indicator of SEP, including childhood SEP, was significantly inversely associated with SROH, and all of the workplace-related factors (social support in the workplace, job stress, working hours and type of employment) were also significantly associated with SROH. Compared with professionals, blue-collar workers had a significantly higher OR of poor SROH and the association was substantially explained by the workplace-related factors; ORs ranged from 1.44 in the age-adjusted and sex-adjusted model to 1.18 in the multivariate model. Poverty during childhood at age 5 and at age 15 was associated with poorer SROH, and these two factors seemed to be independently associated with SROH.

CONCLUSIONS

We found oral health disparity across SEP among workers in Japan. Approximately 60% of the association between occupation and SROH was explained by job-related factors. Economic difficulties during childhood appear to affect SROH in adulthood separately from sex, age and the current workplace-related factors.

A qualitative study of the factors that influence mothers when choosing drinks for their young children

Background

The consumption of sweetened beverages is a known common risk factor for the development of obesity and dental caries in children and children consume sweet drinks frequently and in large volumes from an early age. The aim of this study was to examine factors that influence mothers when choosing drinks for their children.

Method

Semi-structured interviews (n = 32) were conducted with a purposive sample of mothers of young children from Victoria’s Barwon South Western Region (selected from a larger cohort study to include families consuming different types of water, and different socioeconomic status and size). Inductive thematic analysis was conducted on transcribed interviews.

Results

Several themes emerged as influencing child drink choice. Child age: Water was the main beverage for the youngest child however it was seen as more acceptable to give older children sweetened beverages. Child preference and temperament: influencing when and if sweet drinks were given; Family influences such as grandparents increased children’s consumption of sweet drinks, often providing children drinks such as fruit juice and soft drinks regardless of maternal disapproval. The Setting: children were more likely to be offered sweetened drinks either as a reward or treat for good behaviour or when out shopping, out for dinner or at parties.

Conclusions

Limiting intake of sweet drinks is considered an important step for child general and oral health. However, the choice of drinks for children has influences from social, environmental and behavioural domains, indicating that a multi-strategy approach is required to bring about this change.

Influence of dental care on children's oral health and wellbeing

BACKGROUND

Dental problems in early childhood can have a very significant effect not only on the oral health of young children but on their quality of life and that of their families. Added to this are the long term risks they carry into the permanent dentition.

AIM

To review current literature on the management of early childhood caries and its influence on wider oral and general health.

RESULTS

Recent studies suggest that the risks for dental caries, periodontal disease, malocclusion and other general health problems including overweight and obesity may be increased in children who have had early childhood caries. Traditional restoration of damaged primary teeth has been shown to have only moderate outcomes depending on the techniques and materials used and the ability of children to cooperate because of age or other factors.

CONCLUSIONS

More recent interesting approaches that seal enamel caries, only partially remove carious dentine or attempt to entirely seal carious dentine lesions merit not only discussion but also longer term investigation. With increasing demands on health funding, dentistry must look at how the most appropriate care can be provided to allow children to reach adulthood with healthy permanent dentitions - something that less than half the population currently achieve.

Epidemiology of dental caries in children in the United Arab Emirates

Dental caries has a significant impact on the general health and development of children. Understanding caries epidemiology is an essential task for the United Arab Emirates (UAE) policymakers to evaluate preventive programmes and to improve oral health. The purpose of this review is to collect and summarise all data available in the published literature on the epidemiology of dental caries in the UAE in children aged under 13 years. This will provide dental health planners with a comprehensive data summary, which will help in the planning for and evaluation of dental caries prevention programmes. Data were collected from the various published studies in PubMed, Academic Search Complete, Google, and the reference lists in relevant articles. Four keywords were used in the search: 'dental caries,' 'epidemiology,' 'prevalence,' and 'UAE'. All studies conducted in the UAE in general or any single emirate that sheds light on the prevalence of dental caries of children under 13 years were included in this literature review. Studies on early childhood caries and factors associated with dental caries were also included. The review comprises 11 published surveys of childhood caries in UAE. The earliest study was published in 1991 and the most recent was published in 2011. The range of decayed, missing and filled primary teeth (dmft) in UAE children (age between 4 years and 6 years) was 5.1-8.4. For the 12-year-old group the decayed missing and filled permanent teeth (DMFT) ranged from 1.6 to 3.24. Baseline data on oral health and a good understanding of dental caries determinants are necessary for setting appropriate goals and planning for preventive oral health programmes. The current data available on the dmft and DMFT indicate that childhood dental caries is still a serious dental public health problem in the UAE that warrants immediate attention by the government and policy makers.

Health-related quality of life and income-related social mobility in young adults

Background

To assess the association of income-related social mobility between the age of 13 and 30 years on health-related quality of life among young adults.

Methods

In 1988-89 n = 7,673 South Australian school children aged 13 years were sampled with n = 4,604 children (60.0%) and n = 4,476 parents (58.3%) returning questionnaires. In 2005-06 n = 632 baseline study participants responded (43.0% of those traced and living in Adelaide).

Results

Multivariate regressions adjusting for sex, tooth brushing and smoking status at age 30 showed that compared to upwardly mobile persons social disadvantage was associated (p < 0.05) with more oral health impact (Coeff = 5.5), lower EQ-VAS health state (Coeff = -5.8), and worse satisfaction with life scores (Coeff = -3.5) at age 30 years, while downward mobility was also associated with lower satisfaction with life scores (Coeff = -1.3).

Conclusions

Stable income-related socioeconomic disadvantage was associated with more oral health impact, and lower health state and life satisfaction, while being downwardly mobile was associated with lower life satisfaction at age 30 years. Persons who were upwardly mobile were similar in health outcomes to stable advantaged persons.

Determinants of tooth loss and chewing ability in mid- and late life in three Swedish birth cohorts

The aim of the research presented is to determine the influence of socio-economic factors in childhood and mid-life on multiple tooth loss and chewing problems in mid- and late life in three Swedish birth cohorts (1903–1910, 1911–1920 and 1921–1925). Longitudinal national Swedish surveys were used for the analysis. Participants were interviewed in mid-life in 1968 and later in life (77–99 years of age) in 2002. Childhood socio-economic positions (SEP) did not result in different odds of multiple tooth loss and chewing problems in mid- and late life, but persons with higher mid-life SEP had lower odds. Persons born into the 1921–1925 birth cohort had significantly lower odds of multiple tooth loss in late life than the 1903–1910 birth cohort. Women had higher odds of losing multiple teeth than men in late life but not mid-life. Neither gender nor childhood and mid-life SEP predicted chewing problems late in life, but older people with multiple tooth loss had higher odds of chewing difficulty than those with mainly natural teeth. Childhood conditions may contribute to multiple tooth loss in mid-life, which subsequently contributes to multiple tooth loss in late life. Tooth loss in late life is strongly associated with difficulty chewing hard food. Prevalence of multiple tooth loss is higher in women than in men in late life but not in mid-life.

Early life conditions, adverse life events, and chewing ability at middle and later adulthood

OBJECTIVES

We sought to determine the extent to which early life conditions and adverse life events impact chewing ability in middle and later adulthood.

METHODS

Secondary analyses were conducted based on data from waves 2 and 3 of the Survey of Health, Ageing, and Retirement in Europe (SHARE), collected in the years 2006 to 2009 and encompassing information on current chewing ability and the life history of persons aged 50 years or older from 13 European countries. Logistic regression models were estimated with sequential inclusion of explanatory variables representing living conditions in childhood and adverse life events.

RESULTS

After controlling for current determinants of chewing ability at age 50 years or older, certain childhood and later life course socioeconomic, behavioral, and cognitive factors became evident as correlates of chewing ability at age 50 years or older. Specifically, childhood financial hardship was identified as an early life predictor of chewing ability at age 50 years or older (odds ratio = 1.58; 95% confidence interval = 1.22, 2.06).

CONCLUSIONS

Findings suggest a potential enduring impact of early life conditions and adverse life events on oral health in middle and later adulthood and are relevant for public health decision-makers who design strategies for optimal oral health.

The ethical imperative of addressing oral health disparities: a unifying framework

Health disparities are preventable differences in the burden of disease or opportunities to achieve optimal health that are experienced by socially disadvantaged population groups. Reducing health disparities has been identified as an ethical imperative by the World Health Organization's Commission on Social Determinants of Health and numerous other national and international bodies. Significant progress has been made over the past years in identifying vulnerable groups, and 'distal' factors including political, economic, social, and community characteristics are now considered pivotal. It is thus unsurprising that the remarkable advances in the science and practice of dentistry have not led to notable reductions in oral health disparities. In this review, we summarize recent work and emphasize the need for a solid theoretical framing to guide oral health disparities research. We provide a theoretical framework outlining pathways that operate across the continuum of oral health determinants during the lifecourse and highlight potential areas for intervention. Because oral health disparities emanate from the unequal distribution of social, political, economic, and environmental resources, tangible progress is likely to be realized only by a global movement and concerted efforts by all stakeholders, including policymakers, the civil society, and academic, professional, and scientific bodies.

Evaluating two oral health video interventions with early head start families

Poor oral health in early childhood can have long-term consequences, and parents often are unaware of the importance of preventive measures for infants and toddlers. Children in rural, low-income families suffer disproportionately from the effects of poor oral health. Participants were 91 parents of infants and toddlers enrolled in Early Head Start (EHS) living in rural Hawai'i, USA. In this quasi-experimental design, EHS home visitors were assigned to use either a didactic or family-centered video with parents they served. Home visitors reviewed short segments of the assigned videos with parents over an eight-week period. Both groups showed significant prepost gains on knowledge and attitudes/behaviors relating to early oral health as well as self-reported changes in family oral health routines at a six-week followup. Controlling for pretest levels, parents in the family-centered video group showed larger changes in attitudes/behaviors at posttest and a higher number of positive changes in family oral health routines at followup. Results suggest that family-centered educational videos are a promising method for providing anticipatory guidance to parents regarding early childhood oral health. Furthermore, establishing partnerships between dental care, early childhood education, and maternal health systems offers a model that broadens potential reach with minimal cost.

Dental visiting history between ages 13 and 30 years and oral health-related impact

BACKGROUND

The aim was to assess the role of visit history factors between the age of 13 and 30 years on oral health-related impact.

MATERIALS AND METHODS

In 1988-89, n=7,673 South Australian school children aged 13 years were sampled with n=4,604 children (60.0%) and n=4,476 parents (58.3%) returning questionnaires. In 2005-06, n=632 baseline study participants responded (43.0% response of those traced and living in Adelaide). Oral health impact was measured at age 30 years using OHIP-14.

RESULTS

Multivariate regression showed that OHIP scores were significantly higher (P<0.05) for those with episodes of relief of pain visits once (β=1.487) or two or more times (β=2.883), and episodes of extraction once (β=1.301) or two or more times (β=3.172). Higher positive dental visit attitude scores were associated with lower OHIP scores (β=-1.265), as were being male (β=-0.637), having a job (β=-1.555) and being tertiary educated (β=-0.632).

CONCLUSIONS

History of adverse dental events between the age of 13 and 30 years such as episodes of relief of pain visits and episodes of extraction was associated with higher impact of oral health problems at age 30 suggesting a cumulative effect.

Longevity of composite restorations in patients with early childhood caries (ECC)

OBJECTIVES

The aim of this retrospective study was to describe the type and extent of composite fillings in a high risk pediatric caries population and analyze restoration survival probability in relation to severity of decay, Black classification, and composite type.

MATERIALS AND METHODS

A total of 1,017 fillings in 855 primary teeth performed under general anesthesia from 2004-2007 were included into this study. All 157 patients had early childhood caries after the classification of Wyne and were recalled for at least 6 months. A total etch adhesive system, in combination with flowable and/or packable composites, was used. Failures were evaluated according to clinical criteria. Survival probability was calculated using Kaplan-Meier survival analysis.

RESULTS

The mean observation period for restorations was 30.9 months, with a success rate of 81.5 %. In 125 cases, restorations failed after an average retention time of 23.6 months, resulting in an annual failure rate of 4.2 %. The reasons for failure were fracture or partial failure (9.6 %), secondary caries (44 %), or complete restoration loss (46.4 %). Fillings in patients with severe decay had significantly lower survival probabilities. No significant differences were found between flowable and packable composites.

CONCLUSIONS

Composite fillings are a long lasting, high-quality treatment option in pediatric patients with a high risk of caries who are treated under general anesthesia. A strict caries prevention regimen should be followed to minimize the loss of restorations caused by secondary caries.

CLINICAL RELEVANCE

Composite fillings are a long lasting, high-quality treatment option in children with early childhood caries treated under general anesthesia.

A systematic review of risk factors during first year of life for early childhood caries

BACKGROUND

Early childhood caries (ECC) describes dental caries affecting children aged 0-71 months. Current research suggests ECC has important aetiological bases during the first year of life. Gaps in knowledge about disease progression prevent the effective and early identification of 'at risk' children.

AIM

To conduct a systematic review of research studies focusing on (a) acquisition and colonization of oral bacteria and ECC and (b) risk and/or protective factors in infants aged 0-12 months.

DESIGN

Ovid Medline and Embase databases (1996-2011) were searched for RCT, longitudinal, cross-sectional and qualitative studies. Two investigators undertook a quality assessment for risk of bias.

RESULTS

Inclusion criteria were met for (a) by four papers and for (b) by 13 papers; five papers were rated medium or high quality. Bacterial acquisition/colonization and modifying factor interrelationships were identified, but their role in the caries process was not clarified. Key risk indicators were infant feeding practices (nine papers), maternal circumstances and oral health (6) and infant-related oral health behaviours (4).

CONCLUSION

This review confirmed that factors occurring during the first year of life affect ECC experience. Despite heterogeneity, findings indicated maternal factors influence bacterial acquisition, whereas colonization was mediated by oral health behaviours and practices and feeding habits.

Occupational stress and self-perceived oral health in Brazilian adults: a Pro-Saude study

The scope of this study is to investigate the association between occupational stress and self-perception of oral health. Data were obtained through a self-administered questionnaire filled out in a Pró-Saúde Study by 3253 administrative technical staff from Rio de Janeiro's State University. Occupational stress was measured by means of a questionnaire elaborated in 1970 by Karasek, duly shortened by Thorell in 1988. Ordinal logistic regression was used for data analysis, subsequently adjusted for three blocks of variables. Workers exposed to high occupational demands and little occupational control and to passive work had higher chances of self-perception of worse oral health, when compared with those exposed to low occupational demands, there being no association observed in those exposed to active work. However, in the multiple regression model the following estimates were reduced in magnitude and lost statistical significance, namely high occupational demands and passive work. Workers exposed to high occupational demands revealed worse self-reported oral health, which seems to be partly explained by health behavior patterns, the presence of oral health problems and seeking dental services at longer intervals than once per year.

Social inequality in oral health

Social inequalities in oral health are observable regardless of the population, the culture, the method of social classification or the measure of oral health or disease. They exist because of socially determined differences in opportunity, behaviours, beliefs and exposure to the myriad factors which determine our oral health. Behaviours and practices which affect oral health are embedded in the normal patterns of everyday life; those (in turn) are socially determined and differ across the continuum of social status. This presentation focuses primarily on social inequalities in incremental tooth loss because (i) it is a condition which has been shown to have the greatest effect on people's oral-health-related quality of life, and (ii) it is cumulative and irreversible. Most of the knowledge base on social inequalities in tooth loss comes from cross-sectional studies; investigating the phenomenon in a birth cohort can be more informative because it allows us to determine what happens to those inequalities through the life course. Data on incremental tooth loss from a longstanding cohort study (the Dunedin Multidisciplinary Health and Development Study) are presented to illustrate the cumulative and pervasive effect of social inequalities and changes in social status between childhood and adulthood.

Oral health and oral health-related behaviour in preschool children: evidence for a social gradient

This study aims to investigate the social gradient in the reported oral health-related behaviour and oral health status of preschool children. Participants were 1,057 children born between October 2003 and July 2004 in Flanders, Belgium. Oral health examinations were performed by trained dentists when the children were 3 and 5 years old (respectively, in 2007 and 2009); data on dietary habits, oral hygiene habits and dental attendance of the children were obtained through structured questionnaires completed by the parents. Maternal educational level, measured in four categories, was used as a proxy of socio-economic status. Logistic and ordinal regressions showed a social gradient for the oral health-related behaviours: a lower educational level of the mother was related to a higher consumption of sugared drinks between meals and to a lower brushing frequency and dental attendance of the child. Children from low-educated mothers also had seven times more chance to present with caries experience than children from mothers with a bachelor degree. Contrary to the expectations, there was a deviation from the gradient in 3-year-olds from the highest educational group showing an increased risk for caries experience (OR = 3.84, 95 % CI = 1.08-13.65). Conclusion. Already in very young children, a graded relationship is observed between socio-economic position, oral health and related behaviours. The results suggest that different approaches are required to promote oral health during early childhood depending on the mother's educational background. As children from the highest social group also have an increased caries risk, specific techniques may be needed.

Oral health locus of control in a Swedish adolescent population

OBJECTIVE

The aim was to test and evaluate the psychometric properties of the Oral Health Locus of Control (OHLoC) instrument and its relation to dental anxiety, self-efficacy and self-perceived oral health among Swedish adolescents.

MATERIALS AND METHODS

A random sample of 758 (63% of 1208 invited) 19-year-old individuals in three residential areas in western Sweden (two rural, one urban) answered a set of questionnaires prior to a dental examination.

RESULTS

The face and content validity of the OHLoC was deemed good in pilot interviews with individuals of the target age. Explorative factor analysis verified the dimensions of the OHLoC sub-scales (internal, external, chance locus of control) with loadings from 0.503 - 0.812, explaining 54.6% of the variance. Construct validity was confirmed in relation to two other psychometric scales, on dental anxiety (DAS) and on general self-efficacy (GSE), with correlations in the expected directions. In multivariate logistic regression analyses, the internal sub-scale displayed the most consistent statistically significant associations with self-perceived oral health, also when accounting for gender, demography and health behavior. There were no significant differences between genders on the OHLoC, but females scored statistically significantly higher on the DAS (p = 0.005) and lower on the GSE (p = 0.021) than males.

CONCLUSIONS

The Swedish version of the OHLoC appears to have acceptable psychometric properties for use in an adolescent population.
