Background: While inequalities in oral health are generally well documented, it is less clear whether such patterns are evident from early childhood. Using four measures of potential inequality, this study examined patterns in oral health for Australian children at ages 2–3 and 6–7 years. Methods: Cross‐sectional data from two cohorts of children in the Longitudinal Study of Australian Children (LSAC) were used to explore associations between reported oral health and four indicators of social disadvantage: socio‐economic position (SEP), residential remoteness, Indigenous status and non‐English speaking background. Results: For both cohorts, lower SEP and Indigenous status were associated with higher odds of poor oral health on all three indicators, and less accessible location was associated with increased odds for caries. Non‐English speaking background was associated with increased odds for caries experience in 2–3 year olds and non‐use of dental services in the older cohort. Inequalities were larger in the older cohort for socio‐economic position and toothbrushing. Conclusions: Marked social disparities in oral health appear as early as 2 years of age and remain evident in school‐age children. Interventions to reduce such disparities should start as early as possible. 相似文献

Abstract – Objectives: The aim of the present study was to examine the prevalence and severity of caries experience in the primary dentition of preschool children and to assess the association of disease distribution with oral hygiene levels, reported oral health behaviours and socio‐demographic factors. Methods: Study samples comprised 1250 3‐year‐old and 1283 5‐year‐old pre‐school children from four distinct geographical areas in Flanders. Information on oral hygiene and dietary habits, oral health behaviours and socio‐demographic variables was collected using questionnaires completed by the parents. Clinical examinations were performed using standardized criteria. Caries experience was recorded at the level of cavitation (d3 level). Simple as well as multivariable logistic regression analyses were performed in order to identify factors associated with prevalence and severity of caries experience. Results: Visible plaque was present in 31% of 3‐year‐olds and 37% of 5‐year‐olds. In 3‐year‐olds, 7% presented with caries experience while this was the case in 31% of 5‐year‐olds. Multivariable logistic regression revealed significant associations, in 3‐year‐olds, of caries experience with presence of dental plaque (OR = 7.93; 95% CI: 2.56–24.55) and reported consumption of sugared drinks at night (OR = 7.96; 95% CI: 1.57–40.51). In 5‐year‐olds, significant associations were seen with age (OR = 7.79; 95% CI: 2.38–25.43), gender (OR = 0.37 with 95% CI: 0.19–0.71 for girls), presence of visible dental plaque (OR = 3.36; 95% CI: 1.64–6.89) and reported habit of having sugar‐containing drinks in between meals (OR = 2.60 with 95% CI: 1.16–5.84 and OR = 3.18 with 95% CI: 1.39–7.28, respectively for 1×/day and > 1×/day versus not every day). In 5‐year‐olds with caries experience (30.8% of total sample), the severity of disease was further analysed (d3mft between 1 and 4 versus d3mft 5 or higher). Multivariable analyses showed a significant association with gender [girls more likely to have higher disease levels; OR = 4.67 (95% CI: 1.65–13.21)] and with presence of plaque (OR = 3.91 with 95% CI: 1.23–12.42). Conclusions: Presence of visible plaque accumulation and reported consumption of sugared drinks were associated with prevalence of caries experience in Flemish preschool children. Severity of disease was associated with gender and with presence of plaque. Results underline the importance of plaque control and diet management from very young age on. 相似文献

Wigen TI, Wang NJ. Caries and background factors in Norwegian and immigrant 5‐year‐old children. Community Dent Oral Epidemiol 2010; 38: 19–28. © 2009 John Wiley & Sons A/S Abstract – Objectives: The purpose of this study was to assess the caries status of 5‐year‐olds in a low caries area, and study associations between dental caries and parent‐related factors: parents’ education, national origin, oral health behaviours and attitudes. Methods: The material consisted of 523 children and was a stratified random sample. Clinical and radiographic examination was performed in 2007. Enamel and dentine caries were recorded at surface level. Parents filled in questionnaires regarding socioeconomic status, their own oral health behaviours and attitudes. Results: Most participants (66%) had no caries experience and 16% had enamel caries only. Dentine caries experience was present in 18% of the children, and 5% had dentine caries experience in five or more teeth. Surfaces with enamel caries constituted half of all surfaces with caries experience. In multiple logistic regression, statistically significant risk indicators for the child having dentine caries experience at the age of five were: having one or both parents of non‐western origin (OR = 4.8), both parents (OR = 3.0) or one parent (OR = 2.1) with low education, parental laxness about the child’s tooth brushing (OR = 2.8), parents’ brushing their own teeth less than twice a day (OR = 2.2) and having parents with frequent sugar intakes (OR = 1.8). Conclusion: Caries prevalence in 5‐year‐olds was strongly associated with parent‐related factors signifying that information on parents’ socioeconomic status, dental behaviours and attitudes should be considered when planning dental services for young children. Our results suggest that the real high risk group is non‐western children whose parents have low education. 相似文献

Objectives: To investigate the association between certain socio‐demographic characteristics and dental health status of 5‐ to 12‐year‐old children attending public kindergarten and primary schools in Piraeus, Greece. Methods: Gender, age, place of residence, immigrant background and area‐based income were associated with dental caries prevalence, treatment needs and oral hygiene level in 5,116 children. Results: The mean number of decayed, missing and filled deciduous teeth (dmft) and Unmet Restorative Treatment Needs Index (UTN) at 6‐year‐olds were 1.54 and 84.6% respectively, and the DMFT and UTN at 12‐year‐olds were 1.35 and 71.8%. Caries experience/severity significantly increased with age, whereas treatment needs and oral hygiene level decreased (P < 0.001). Immigrant background and low area‐based income was associated with poorer oral health outcomes. The above associations retained statistical significance after multivariate analysis. Children who live in areas with lower average income present 1.20 to 2.14 greater risk of having higher caries severity and poorer oral hygiene in comparison to those living in more affluent areas, and children with an immigrant background have 1.68 to 4.34 higher likelihood to present higher dmft and DMFT values, higher unmet treatment needs, and poorer oral hygiene levels compared to their Greek counterparts above and beyond the effect of the other risk factors assessed. Conclusions: The present study revealed a socio‐demographic gradient in oral health status and treatment needs of children in Piraeus, Greece. 相似文献

Summary. Objectives. The objectives of the study were: (i) to assess the level of dental knowledge and attitudes towards child dental care among parents in Jordan, (ii) to analyse the oral health care habits of schoolchildren and parents, and (iii) to evaluate the oral hygiene habits and use of professional dental services of children in relation to socio‐demographic conditions. Design. Cross‐sectional, self‐administered questionnaires for parents. Sample and methods. National representative sample of 6–16‐year‐olds living in urban areas (n = 1556, children and parents, response rate 92%, 48·7% boys, 51·3% girls). Results. In all, 80% of the parents knew about the harmful effect of sugar and 79% thought that poor oral hygiene may induce dental caries. In addition to proper oral hygiene (79%) and restriction of sugar/sweets (42%), 36% of the parents emphasized regular dental visits for the prevention of dental disease in children. However, most children saw a dentist for symptomatic reasons only (86%), while 11% attended for dental check‐ups. At their last visit to the dentist, 49% of the children had tooth extraction and only 8% had preventive services (fissure sealing). Toothbrushing at least twice a day was reported for 31% of the children; 14% of children aged 6–9 years had assistance from adults in brushing. Dental care habits of children were highly affected by dental visiting habits of parents, and variations by level of education of parents were also found. Conclusions. The discrepancy between dental knowledge and attitudes of parents and oral health care practices indicate the need for oral health education. School‐based oral health promotion programmes should be established in Jordan to influence the oral health behaviour of children and parents and to avoid further deterioration in their oral health. 相似文献

This study assessed and compared oral health and oral‐health behaviours among children with and without attention deficit hyperactivity disorder (ADHD). The study included 31 children, 12–18 yr of age, with ADHD and 31 age‐ and gender‐matched children without ADHD. Clinical data were recorded by a trained and calibrated examiner for caries, traumatic dental injuries, periodontal health, tooth wear, and salivary function. A questionnaire was also given to parents or caregivers about the oral health habits and behaviours of these children. Data were compared using Mann–Whitney U‐tests and chi‐square tests. No significant differences were found between children, with or without ADHD, in caries extent or prevalence, dental trauma prevalence, prevalence of periodontal disease or plaque, tooth wear, or unstimulated salivary flow. Children with ADHD had a significantly higher percentage of sites with gingival bleeding, as well as a higher frequency of parent‐reported dislike of dentists, bruxism, history of assisted toothbrushing, and toothbrushing duration <1 min. They also had higher attendance at government dental clinics. The findings indicate that children with ADHD have poorer oral hygiene and more adverse oral‐health attitudes and behaviours than do children without ADHD. 相似文献

Objectives : A national representative study to describe oral health behaviour, illness behaviour, oral health knowledge and attitudes among 12‐year‐old and 18‐year‐old Chinese, to analyse the oral health behaviour profile of the two age groups in relation to province and urbanisation, and to assess the relative effect of socio‐behavioural risk factors on dental caries experience. Methods : The total number of 4,400 of each age group were selected and data were collected by clinical examinations (WHO criteria) and self‐administered structured questionnaires. Results : 44.4% of the respondents brushed their teeth at least twice a day but only 17% used fluoridated toothpaste. Subjects who saw a dentist during the previous 12 months or two years were 31.3% and 35.3% for 12‐year‐olds and 22.5% and 20.2% for 18‐year‐olds, respectively. Nearly one third (29%) of 12 year‐olds and 40.5% of 18‐year‐olds would visit a dentist in case of signs of caries but only when in pain. Nearly half of the participants (47.2%) had never received any oral health care instruction. Significant variations in oral health practices were found according to province and regular dental care habits were more frequent in urban than in rural areas. The risk of dental caries was high in the case of frequent consumption of sweets and dental caries risk was low for participants with use of fluoridated toothpaste. Conclusion : Systematic community‐oriented oral health promotion programmes are needed to target lifestyles and the needs of children, particularly for those living in rural areas. A prevention‐oriented oral health care policy would seem more advantageous than the present curative approach. 相似文献

OBJECTIVES: Immigrant children make up a large proportion of the school populations in many western cities. It is likely that their parents have different attitudes and knowledge of dental health than resident populations, and thus provide a challenge to public dental services. This study sought to map existing disparities in oral health among immigrant and western native children in Oslo and to identify differences in parental, cultural and ethnic beliefs and attitudes towards oral health and caries-related behaviours. METHODS: Caries was recorded of 735 children (3- and 5-year olds), supplemented with radiographs among 5-year olds. Their parents responded to a questionnaire. RESULTS: Immigrant background, consumption of sweet drinks at bed and social status were the dominant caries risk indicators among the 3-year olds. Among the 5-year olds, the caries risk indicators were immigrant background, parental indulgence, attitude to diet, attitude to oral hygiene, social status and age starting toothbrushing. Being an immigrant was closely associated with higher caries prevalence and experience. Parental attitudes to oral hygiene, diet and indulgence, and caries-related behaviours distinguished immigrants from western natives. CONCLUSIONS: The results suggest that immigrant groups in western societies require different information packages, modified strategies for forming oral hygiene habits and attitudes related to dental care of children, and encouragement to exercise discipline on factors known to be risks for oral health. These strategies must recognize that immigrants and western natives attach different levels of importance to oral health and dental parameters. It should be paid extra attention to some caries high-risk subgroups. 相似文献

Aim : This study assesses disparities in the oral health status of Brazilian black and white children. Participants : 11‐and 12‐year‐old schoolchildren living in 131 cities of the State of São Paulo, Brazil. Methods : Spatial data analysis of city‐level indexes of oral health, socio‐economic status and provision of dental services. Main outcome measures : Ethnic ratios of the DMFT and the care index. Results : White children had higher indexes of caries in permanent teeth than their black counterparts, concurrent with a higher utilisation of dental attendance. The gap of caries prevalence between black and white children was reduced in cities with a better profile of socio‐economic status. Cities with higher per‐capita yearly budget, expenditure in health, and provision of public dental services presented reduced indications of ethnic inequality in dental care. Conclusion : The knowledge of conditions associated with a lower ethnic discrepancy in the risk of caries and in the incorporation of dental services can be used to design socially appropriate dental services. An improved community dental service, higher public expenditure in health and per‐capita municipal yearly budget contribute effectively to reducing inequities in oral health by allowing an incorporation of restorative dental treatment more equitably distributed between black and white children. 相似文献

Aim : To identify and discuss geriatric oral health issues in Australia. Methods : A discussion of the demographic trends, oral health trends, and barriers to dental care for older Australians is presented, together with a review of Australian public and private sector geriatric dental services, geriatric dental research, and geriatric dental education. Conclusions : Key geriatric oral health issues for Australia include: edentulism is decreasing and older Australians are retaining more natural teeth; coronal and root caries are significant problems, especially as older adults become more functionally dependent, cognitively impaired, and medically compromised; the oral health status of institutionalised older Australians is poor; the onset of severe oral diseases appears to occur in many older Australians prior to their institutionalisation, when they are homebound and dependent upon carers; carers of older adults do not have access to practical education about dental care; the majority of older Australians are eligible to use public‐funded dental services, but barriers limit their access to these services; few Australian public or private dental services are designed with a geriatric focus; geriatric dental education does not have a high profile in Australian dental schools; no specialty exists in Australia for geriatric dentistry, nor is there a national geriatric dentistry association. 相似文献

Abstract – Objectives: To determine predictors of untreated dental decay among 15–34‐year‐olds in Australia. Methods: Data were from Australia’s National Survey of Adult Oral Health, a representative survey that utilized a three‐stage, stratified clustered sampling design. Models representing demographic, socioeconomic, dental service utilization and oral health perception variables were tested using multivariable logistic regression to produce odds ratios. Results: An estimated 25.8% (95% CI 22.4–29.5) of 15–34‐year‐old Australians had untreated dental decay. After controlling for other covariates, those who lived in a location other than a capital city had 2.0 times the odds of having untreated dental decay than their capital city‐dwelling counterparts (95% CI 1.29–3.06). Similarly, those whose highest level of education was not a university degree had 2.1 times the odds of experiencing untreated dental decay (95% CI 1.35–3.31). Perceived need of extractions or restorations predicted untreated coronal decay, with 2.9 times the odds for those who perceived a treatment need over those with no such treatment need perception (95% CI 1.84–4.53). Participants who experienced dental fear had 2.2 times the odds of having untreated dental decay (95% CI 1.38–3.41), while those who reported experiencing toothache, orofacial pain or food avoidance in the last 12 months had 1.9 times the odds of having untreated dental decay than their counterparts with no such oral health‐related quality‐of‐life impact (95% CI 1.20–2.92). The multivariate model achieved a ‘useful’ level of accuracy in predicting untreated decay (area under the ROC curve = 0.74; sensitivity = 0.63; specificity = 0.73). Conclusions: In the Australian young adult population, residential location, education level, perceived need for dental care, dental fear, toothache, orofacial pain or food avoidance together were predictors of untreated dental decay. The prediction model had acceptable specificity, indicating that it may be useful as part of a triage system for health departments wishing to screen by means of a questionnaire for apparently‐dentally healthy 15–34‐year‐olds. 相似文献

Objectives: To identify the predictors of early childhood caries and urgent dental treatment need among primarily African‐American children in child care centers in the Delta region of Mississippi. The purpose of this study was to replicate predictors of caries and urgent dental treatment needs that were identified in an earlier study conducted in Delta child care centers and to assess additional caries risk factors not collected in the original study. Methods: Children in 19 child care centers were examined by the dentists, and the parents provided data on oral health practices, oral health history, and on children's oral health‐related quality of life (QOL). The dentists also assessed visible plaque and tested levels of mutans streptococci. Predictors of caries and treatment need among children 24 to 71 months of age were examined using logistic regression. Results: Two parent predictors of caries identified in the earlier study (parent flossing and soft/sugary drink consumption) were not predictive in the current study. Parent history of abscess continued to predict their child's urgent need for treatment. Young children's level of salivary mutans streptococci, maxillary incisor visible plaque, and parents' reports of child oral health‐related QOL measures predicted the presence of both caries and urgent treatment need. Some expected predictors, such as frequency of child's toothbrushing, were not predictive of caries. Conclusions: Parental abscess and parent's report of the child's oral health‐related QOL are risk indicators for poor oral health outcomes that could be used by nondental personnel to identify young children in need of early preventive intervention and dental referral. 相似文献

BACKGROUND: In light of the various challenges faced by public dental health services, especially when large geographical areas and isolated communities are concerned, targeting of high risk groups within these populations needs to be investigated. This study aimed to assess caries experience, dental health behaviour and dental service utilization among a sample of pre-school children in a rural community in Western Australia. METHODS: The study was a cross-sectional oral health survey of pre-school children between the ages of 2 and 5 in Carnarvon, Western Australia. RESULTS: In total, 70 pre-school children (representing approximately 15 per cent of the total 2-5 year old population of Carnarvon) were examined. Less than half of the children were caries free. Both caries prevalence and severity (mean dmft) were significantly higher among Aboriginal children than non-Aboriginal children. Caries prevalence and severity were also significantly higher among children who often consumed carbonated drinks. CONCLUSIONS: This survey indicates that some pre-school children in rural areas, and especially Aboriginal pre-school children, are at high risk of developing dental caries. Effective oral health programmes commencing well before the usual first contact with dental services at age 5 are needed for young children at high risk of dental caries. 相似文献

Abstract – Objectives: The study aimed to explore the association between parental smoking behavior and caries experience in young children, taking into account the socioeconomic status and oral health‐related behavior. Methods: Cross‐sectional data from 1250 3‐year‐old and 1283 5‐year‐old children from four geographical areas in Flanders (Belgium) were analyzed. Children were examined at school by trained dentist‐examiners, using standard criteria and calibrated examination methodology. Data on oral hygiene and dietary habits, oral health behavior, sociodemographic variables, and parental smoking behavior were obtained through structured questionnaires, completed by the parents. Results: Visible caries experience (i.e. d3mft > 0) was seen in 7% of 3‐year olds and 31% of 5‐year olds. In both age groups, 30% of the parents reported smoking behavior. Univariable logistic regression analysis with caries prevalence as the dependent variable, revealed that parental smoking was a significant independent variable. After controlling for age, gender, sociodemographic characteristics, oral hygiene, and dietary habits, the effect of family smoking status was no longer significant in 3‐year‐old children (OR = 1.98; 95% CI: 0.68–5.76). In 5‐year olds the significant relationship between parental smoking behavior and caries experience persisted after adjusting for the other evaluated variables (OR = 3.36; 95% CI: 1.49–7.58). Conclusion: The results of this study illustrate the existence of a significant association between parental smoking behavior and caries experience in 5‐year‐old children. 相似文献

Objectives. To assess the prevalence of untreated dental caries in children with cerebral palsy and to assess socio‐demographic, behavioural, and clinical covariates. Design. Cross‐sectional assessment of 200 children and adolescents with cerebral palsy (2–17 years old) enrolled in a specialized healthcare unit in São Paulo, Brazil. The dental examination followed the World Health Organization's guidelines for oral health surveys; familial caretakers informed on socio‐economic status and behaviour; the patient's medical record informed their clinical status. Results. The proportion of children that presented at least one tooth affected by untreated caries was 49.5%. Poor socio‐economic standings and a higher frequency of sugar consumption associated with a worse profile of dental health; different types of cerebral palsy (spastic, tetraparesis) did not. The prevalence of untreated caries was higher than reference values assessed for the overall population of the same age range. Conclusions. The high burden of untreated dental caries on cerebral palsy patients reinforces the importance of the dentist in the interdisciplinary healthcare team attending these children. Factors associated with this outcome are the same for the general population; these findings underscore the necessity of implementing effective caries prevention in this population of cerebral palsy children. 相似文献

Objectives. This qualitative study was designed to record the perception by Newcastle children of the influences on their choice of drinks and their knowledge of the dental health problems caused by acidic drinks. Methods. Four focus groups, each involving 8 Newcastle schoolchildren (4 boys and 4 girls) formed the basis of the study. Two age groups, 13–14‐year‐olds and 8–9‐year‐olds, and two socio‐economic groups were investigated, using state schools in Newcastle upon Tyne. A moderator guided the children to discuss their choice of drink and its dental effects amongst themselves. Results. In total, 32 children participated in the focus groups and the results suggested that 8–9‐year‐olds preferred still, fruit‐flavoured drinks whilst 13–14‐year‐olds preferred carbonated drinks. Taste was the most important influence on drink choice in all age groups. Parents and friends were more influential in younger children, whilst cost, availability and thirst were more important to older children. Younger children did not believe advertisements whilst older children thought they might work if seen enough times. Dental knowledge was confused in all age groups and only the 13–14‐year‐old‐high socio‐economic groups knew that acidic drinks were bad for the teeth. Different methods for addressing the problem of erosion were suggested by different age groups. There was very little difference between the socio‐economic groups in the areas discussed. Conclusions. The children's knowledge of dental diseases and the effect of drinks on the teeth were confused. The factors that influence drink choice appear to change with age, rather than socio‐economic status. 相似文献

Kirkeskov L, Kristiansen E, Bøggild H, von Platen‐Hallermund F, Sckerl H, Carlsen A, Larsen MJ, Poulsen S. The association between fluoride in drinking water and dental caries in Danish children. Linking data from health registers, environmental registers and administrative registers. Community Dent Oral Epidemiol 2010; 38: 206–212. © 2010 John Wiley & Sons A/S Abstract – Objectives: To study the association between fluoride concentration in drinking water and dental caries in Danish children. Methods: The study linked registry data on fluoride concentration in drinking water over a 10‐year period with data on dental caries from the Danish National Board of Health database on child dental health for 5‐year‐old children born in 1989 and 1999, and for 15‐year‐old children born in 1979 and 1989. The number of children included in the cohorts varied between 41.000 and 48.000. Logistic regression was used to assess the correlations, adjusting for gender and taxable family income as a proxy variable for socioeconomic status. Results: Fluoride concentration in drinking water varied considerably within the country from very low (<0.10 mg/l) to more than 1.5 mg/l. Only little variation was found over the 10‐year study period. Dental caries in both 5‐year‐olds and 15‐year‐olds decreased over the study period. An inverse relation between the risk of dental caries and fluoride concentration in drinking water was found in both primary and permanent teeth. The risk was reduced by approximately 20% already at the lowest level of fluoride exposure (0.125–0.25 mg/l). At the highest level of fluoride exposure (>1 mg/l), a reduction of approximately 50% was found. Similar findings were found if analysis was limited to children residing in the same place during the entire study period. Conclusions: The study confirmed previous findings of an inverse relation between fluoride concentration in the drinking water and dental caries in children. This correlation was found in spite of the extensive use of fluoridated toothpaste and caries‐preventive programs implemented by the municipal dental services in Denmark. Linking Danish health registers with environmental and administrative registers offers an opportunity for obtaining sample sizes large enough to identify health effect, which otherwise could not be identified. 相似文献

Data on the dental health of Australian school children from 1977 to 1985 have previously been reported. Significant features included a secular decline in caries experience as defined by the number of decayed, missing and filled teeth in both the deciduous dentition (dmft index) and permanent dentition (DMFT index), and a change in the distribution of caries experience within the child population in Australia, indicated by increasingly smaller percentages of children accounting for greater proportions of total disease experience. The aim of the present paper was to extend the annual reporting on caries experience in Australia up to and including 1993, and to document the change in the distribution of caries within the child population since 1977. In addition, the data are compared with dental targets for children for the year 2000 in Australia and internationally. Caries data were obtained for the years 1977–1993 for children who were patients at School Dental Services in each State and Territory of Australia. Caries experience was recorded by uncalibrated dentists and dental therapists during routine dental examinations. From 1977-89 data were weighted by State and Territory estimated resident populations. From 1989, the data were stratified according to age, year, and State, and weighted to reflect proportions in the national estimated resident population for each State/age stratum. Between 1977 and 1993 there has been a decline in caries experience for 6 year old children from a dift? of 3.13 to a dmft of 1.90, and an increase in the per cent with dmft=0 from 33.1 per cent to 53.2 per cent with dmft=0 in 1993. Over the same time period the DMFT for 12 year olds reduced from 4.79 to 1.10 and the per cent while DMFT=0 increased from 10.5 per cent to 53.1 per cent. Projection of the decline in DMFT indicates the dental health target for 12 year old children of DMFT=1.0 by the year 2000 should have been achieved by the end of 1995 相似文献
