Disparities in dental service utilization among Alabama Medicaid children

OBJECTIVES: Access to oral health care and utilization of available services are important factors in minimizing the oral health disparities among underserved minorities. Our objective was to evaluate the racial and other factors related to 'realized access' to oral health care among Alabama Medicaid children. METHODS: Data were obtained from 308 538 Alabama Medicaid claims submitted in 1995-96 and analyzed using regression analyses. RESULTS: A lower proportion of Blacks (24%) and other racial groups (22%) compared to Whites (31%) and a lower proportion of 15-19-year-olds (15%) compared to younger age groups (30%) obtained dental services (P < 0.05). Odds of males obtaining care were slightly lower compared to females (OR = 0.96; 95% CI = 0.94-0.99). However, there was a significant interaction of race with other factors in determining service utilization. Subjects who were continuously eligible for Medicaid throughout the fiscal year were more likely to obtain care (OR = 2.86; 95% CI = 2.78-2.93). About one-fourth of the visits had an emergency procedure included in the treatment rendered. Availability of a participating dentist within the county of residence and the lower reimbursement-to-charge ratio were among the other related factors for underutilization of services. CONCLUSIONS: There is a significant racial disparity in utilization of dental services even among the Medicaid-eligible children. However, this was not a simple function of race, but a complex interaction of race with other factors such as age, gender, and location. ACKNOWLEDGMENT: Supported by CDC grant #U48/CCU 409679.     

Community-based Sealant Programs in the United States: Results of a Survey

The appropriate use of pit and fissure sealants could reduce substantially the majority of occlusal caries among US school-aged children. The 1986–87 national oral health survey conducted by the NIDR showed that less than 8 percent of the children 5–17 years of age had sealants on their teeth. The purpose of this national study was to document the current status of community-based sealant programs and to identify general program characteristics. Data were gathered through a mail survey to all state dental directors and site visits to four selected comprehensive community-based programs. Twentynine states were currently conducting sealant programs. The vast majority of these programs had formal quality assurance systems and companion health education components. Eight states indicated that sealant programs had been terminated within the last two years. Medicaid reimbursement for sealants was available in 42 states, with a mean reimbursement rate of $10.71 per sealant. Reimbursement rates ranged from $3.00- $20.00 per sealant. State practice acts almost uniformly permitted the placement of sealants by dental hygienists (n = 48), but less frequently by dental assistants (n = 15). Approximately 43 percent of state practice acts did not require a dentist to be present physically when auxiliaries place sealants in public/community sealant programs. All respondents indicated that there was a need for additional programs in their state. No structural factors—for example, level of Medicaid reimbursement for sealants or state practice act requirements for auxiliary supervision—were found to be associated with the presence of community-based sealant programs. Nationally, only a small percentage of children appeared to be receiving sealants in community programs.     

Dental caries and associated factors in 12-year-old schoolchildren in Thiruvananthapuram, Kerala, India

OBJECTIVES: The aims of the present study were to describe the dental health status of 12-year-old schoolchildren in Thiruvananthapuram, Kerala, India, and to identify sociodemographic factors, oral health behaviours, attitudes and knowledge related to dental caries experience. METHODS: The study took the form of a cross-sectional survey of 838 children in upper primary schools. A two-stage cluster sampling technique was used. Dental caries was measured using World Health Organization criteria. Sociodemographic factors, oral health behaviours, attitudes and knowledge were assessed by a self-administered questionnaire. RESULTS: The prevalence of dental caries in the permanent dentition was 27%. The mean number of decayed, missing and filled teeth was 0.5 (SD=0.9). The decayed component (D) constituted 91% of the total number of decayed, missing and filled teeth (DMFT). Multiple logistic regression analysis showed that children had a higher risk of having dental caries if they lived in urban area [OR=1.5, 95% confidence interval (CI)=1.1-2.1], had visited a dentist (OR=1.6, 95% CI=1.2-2.2), did not use a toothbrush (OR=1.9, 95% CI=1.2-2.9), consumed sweets (OR=1.4, 95% CI=1.0-1.9) or performed poorly in school (OR=1.7, 95% CI=1.0-2.3). CONCLUSIONS: The prevalence of caries in this sample of 12-year-old schoolchildren was low compared to that in other developing countries. The present study indicated that urban living conditions were associated with more dental caries. Since urbanization is rapid in India, oral health promotion at the present time would be valuable to prevent increased caries prevalence.     

The prescription and outcomes of fissure sealants applied to a group of high caries risk children by general dental practitioners working in the North West of England

OBJECTIVE: To describe the use and outcomes of fissure sealants applied to the first permanent molars (FPMs) of children with high caries risk. DESIGN: Retrospective cohort study. SETTING: General dental practices in North West England. PARTICIPANTS: 677 children between the ages of 5 and 14 years who had dmfs > or =2, and regularly attended 50 general dental practitioners. OUTCOMES: Analyses were performed at patient level. Logistic regression models, taking into account the clustering of subjects within dental practices, were fitted to identify whether the decision to fissure seal FPMs was significantly associated with gender, socio-economic status, number of carious primary teeth and percentage of carious primary teeth filled. Similar logistic regression models were fitted for caries experience in FPMs. RESULTS: Poorer children were significantly (p < 0.05, OR = 0.84, 95% CI = 0.71, 0.99) less likely to receive fissure sealants than affluent children, whilst girls (p < 0.01, OR = 1.54, 95% CI = 1.12, 2.12) were more likely to have sealants than boys. The total number of carious primary teeth was also a significant (p < 0.01, OR = 1.15, 95% CI = 1.06, 1.25) independent predictor of dentists' decisions to fissure seal FPMs. For each carious primary tooth, the odds of having caries in FPMs increased by 1.16 (95% CI = 1.06, 1.26). Analysis showed that pit and fissure caries in FPMs was not affected by the presence or absence of fissure sealants. CONCLUSIONS: The decision to fissure seal FPMs is affected by caries experience in the primary dentition. Girls and affluent children were more likely to receive fissure sealants. It appears that the placement of fissure sealants by general dental practitioners was not effective in preventing pit and fissure caries in these high-risk children.     

Dental caries experience of Kuwaiti schoolchildren

OBJECTIVE: This study was designed to measure the dental caries experience of Kuwaiti schoolchildren. METHODS: A national epidemiologic survey of the 5-14 year old children (n = 4,588) was conducted in the 5 governorates of Kuwait in 2001. Eight trained and calibrated dentists examined the children. Dental caries was scored using WHO criteria. RESULTS: In the primary dentition, the percentage of 5- and 6-year-old children with dft = 0 was 12.6% and 14.4% respectively. The corresponding mean dft/dfs for 5- and 6-year-olds were 4.6/9.7 and 4.6/9.9. For the permanent dentition, the percentage of 12- and 14-year-old children with DMFT = 0 was 26.4% and 21.7% respectively. The corresponding mean DMFT/DFS figures for 12- and 14-year-olds were 2.6/3.4 and 3.9/4.2. The d/D component was the major contributor to these mean scores. Poor oral hygiene (OR = 2.0; 95% CI = 1.7 - 2.4) and increasing age (OR = 1.4; 95% CI = 1.3 - 1.5) were significantly associated with caries risk in the permanent dentition. CONCLUSIONS: Caries levels are similar to those in neighbouring and other Middle East countries. There is a clear need for expanding the national school oral health programme to reach those children who are not yet receiving systematic preventive and curative services. Further studies are required to monitor the effect of the extensive caries preventive programme now in place in Kuwait.     

Statistical model for assessing the impact of targeted,school-based dental sealant programs on sealant prevalence among third graders in Ohio

OBJECTIVES: Since Ohio school-based dental sealant programs target economically disadvantaged groups, simple comparison of sealant prevalence between schools with sealant programs and those without is problematic due to underlying disparities between the two in sealant prevalence. The goal of our analysis was to estimate the impact of sealant programs on sealant prevalence among third graders in Ohio by applying a statistical model to data from a 1998-99 Ohio oral health screening survey of schoolchildren to control for differences in background characteristics. METHODS: Included in the analysis were 9,747 third graders at randomly selected schools in Ohio. Chi-square statistics and survey logistic regression were used to analyze the association of sealant presence with school sealant program participation, dental care payment method, sex, race, and school lunch program eligibility. RESULTS: The unadjusted odds ratio for dental sealant presence was 3.4 (95% confidence interval [CI]=2.6, 4.4; P<.01). Adjusting for race and income, the odds of having dental sealants among children in schools with dental sealant programs increased to 4.8 (95% CI=3.5, 6.5; P<.01). CONCLUSIONS: Not controlling for confounders can result in underestimation of the impact of targeted school sealant programs.     

Does Medicaid improve utilization of medical and dental services and health outcomes for Medicaid‐eligible children in the United States?

BACKGROUND: Data are lacking to support the contention that Medicaid services improve utilization of healthcare services and result in better health. OBJECTIVE: To compare sociodemographic, utilization of healthcare services and health status characteristics among Medicaid-eligible children. METHODS: The third National Health and Nutrition Examination Survey included 2821 children 2-16 years of age eligible for Medicaid. The main outcome measures are annual physician visit, annual dentist visit, general health status, oral health status, asthma (second most common childhood disease), dental caries (most common childhood disease), asthma treatment needs, and dental treatment needs. We quantified the association of these outcome measures with Medicaid insurance status and sociodemographic status using multiple logistic regression modeling, taking into account the complex survey design and sample weights. RESULTS: Among Medicaid-eligible children, 27% were uninsured. Among uninsured Medicaid-eligible children, 62% had an annual physician visit, 32% had an annual dentist visit, 10% needed asthma treatment, and 57% needed dental treatment. Among insured Medicaid-eligible children, 81% had an annual physician visit, 39% had an annual dentist visit, 13% needed asthma treatment, and 42% needed dental treatment. After simultaneously taking into account other characteristics, uninsured Medicaid-eligible children were more likely to not have an annual physician visit (OR(NoMDvisit) = 2.21; 1.26-3.90), and to need dental treatment (OR(DentalNeed) = 1.57; 1.13-2.18). CONCLUSIONS: This USA population-based study found disparities exist within Medicaid's services between utilization of dental and medical services. Medicaid insurance improved utilization of medical services, but did not improve the utilization of dental services. This suggests that Medicaid insurance does not improve access to dental services for poor children.     

High educational attainment moderates the association between dental health‐care supply and utilization in Europe

In line with the theory of supplier‐induced demand, an increased physician density often goes along with a higher utilization of medical services, including dental services. This study aimed to assess whether dentist density and self‐employment are related to dental care use, and whether these relationships are moderated by patients' educational attainment. We used data from the Survey of Health, Ageing, and Retirement in Europe (SHARE) from over 20,000 respondents, 50 + yr of age, in 13 countries. We conducted multilevel logistic regressions with probability and type of dental treatment on individual education, country‐specific dentist density, and dentist remuneration, and their cross‐level interaction. Patients with a high educational level were more likely to report a dentist visit (OR = 2.1, 95% CI: 1.912–2.305) and to receive preventive care (OR = 1.9, 95% CI: 1.697–2.043) than those with a low educational level (reference category). Cross‐level interaction effects indicated that high dentist density decreases dental care utilization differences between patients with high (OR = 0.996, 95% CI: 0.993–0.999), medium (OR = 0.995, 95% CI: 0.991–0.999), and low education levels. This was also true for prevention use (OR = 0.996, 95% CI: 0.992–0.999 for patients with a high education level, and OR = 0.996, 95% CI: 0.993–1.000 for patients with a medium education level). The findings suggest that although dentist density is positively associated with dental care utilization, patients have differing susceptibilities to dental care supply.     

The oral health and treatment needs of schoolchildren in Trinidad and Tobago: findings of a national survey

OBJECTIVE: To describe the oral health and treatment need of schoolchildren in Trinidad and Tobago. DESIGN AND METHOD: Cross-sectional survey using stratified cluster sampling. Participants were children in primary (aged 6-8 years) and secondary school (aged 12 and 15 years). Main outcome measures were DMFT/dmft, treatment need, and fluorosis. RESULTS: Examinations were completed on 1064 children. The dmft of the 6-8-year-olds was 2.54 (95% CI = 2.32, 2.76). For 12-year-olds, the DMFT was 0.61 (95% CI = 0.51, 0.71), whereas for 15-year-olds, the DMFT was 1.06 (95% CI = 0.87, 1.25). Most of the caries experience in 6-8-year-olds was from decayed teeth. Sixty-seven per cent of the sample (95% CI = 64%, 69%) had some type of treatment need. Most frequently occurring need was for fillings at 42% (95% CI = 40%, 44%) with 28% (95% CI = 26%, 31%) of the total sample needing two or more surface fillings, followed by fissure sealants at 33% (95% CI = 30%, 36%) and caries-arresting care at 12% (95% CI = 10%, 14%). Extraction of one or more teeth was needed in 13% (95% CI = 11%, 15%) of children. Rates of fluorosis were negligible. CONCLUSION: The caries experience of 12- and 15-year-old children were low but was high for schoolchildren aged 6-8 years, in terms of prevalence and severity. Effective oral health promotion strategies need to be implemented to improve the oral health of primary schoolchildren in Trinidad and Tobago.     

Assessment of retention rates and clinical benefits of a community sealant program

PURPOSE: The purposes of this study were to: (1) evaluate the retention rates of occlusal sealants in children in an urban school-based sealant program run by a County Health Department in Alabama; and (2) assess the clinical benefits of this sealant program by comparing caries experience of a group of participants and nonparticipants. METHODS: The records of 2,097 children (mean age=8.1 +/- 1.6 years) who received sealants and had at least 1 follow-up examination were analyzed to determine the outcome of sealed and nonsealed surfaces of permanent first molars (PFM). Additionally, 103 fifth-grade students who did and did not participate in the sealant program (P=participants; NP=nonparticipants) were examined by a masked examiner who recorded their PFM condition. RESULTS: Sealants placed by the County Health Department had a retention rate of 71% over an average of 1.6 +/- 0.7 years (range=0.5-4.4 years). The patient's age at the initial visit appeared to be the only factor that influenced retention. On average, participants had at least 1 PFM that remained caries-free, compared to nonparticipants (permanent decayed, missing, and filled teeth [DMFT] in NP=1.5 +/- 1.4, P=0.5 +/- 0.8; P<.016). CONCLUSIONS: Retention rates for occlusal sealants in this public health program were similar to those reported in previous clinical studies. Furthermore, children who had sealants had significant protection from occlusal decay up to grade 5.     

Maternal health and lifestyle, and caries experience in preschool children. A longitudinal study from pregnancy to age 5 yr

In this study, associations were explored between maternal health and lifestyle during pregnancy and in early motherhood, and preschool children's caries experience. The study was based on the Norwegian Mother and Child Cohort Study conducted by the Norwegian Institute of Public Health and on data from the Public Dental Services. A total of 1348 children were followed from pregnancy to age 5 yr. A clinical dental examination was performed at age 5 yr. Questionnaires were completed by the mothers during pregnancy and in the first 18 months of their child's life, and as part of the dental examination. Results from the multivariate logistic regression analysis showed that having an obese mother (OR = 2.3, 95% CI: 1.3-4.1), a mother who consumed a diet containing more fat (OR = 1.6, 95% CI: 1.1-2.5) or sugar (OR = 1.5, 95% CI: 1.1-2.3) than recommended, a mother with low education (OR = 1.5, 95% CI: 1.1-2.3) or one or both parents of non-western origin (OR = 5.4, 95% CI: 2.8-10.6) were statistically significant risk indicators for caries experience at age 5 yr. In conclusion, maternal weight and intake of sugar and fat in pregnancy were associated with caries experience in preschool children. These characteristics may enable early referral to the dental services and preventive care to be delivered.     

Are Oral Health Status and Care Associated with Anxiety and Depression? A Study of Portuguese Health Science Students

The relationship between oral health and anxiety/depression were assessed in a cross-sectional study conducted in 388 Portuguese students from the Health Sciences (age: 21 +/- 3 years, 75% women). Oral health included prevalence of reported tooth pain/gum bleeding, dentist attendance, and dentifrice and dental floss use. Anxiety and depression were assessed by the Hospital Anxiety and Depression Scale. Subjects with anxiety or depression had a higher frequency of perceived gum bleeding and reported a higher dentist attendance than normal subjects. On multivariate analysis, anxiety was significantly and independently related to perceived toothache (OR = 2.90, 95% CI: 1.25-6.72) and dentist attendance (OR = 2.15, 95% CI: 1.18 - 3.91) whereas depression was associated with perceived gum bleeding (OR = 4.96, 95% CI: 1.68 - 14.59), and no differences were found regarding teeth brushing or dental flossing. The author concludes that anxiety and depression are related to perceived toothache and gum bleeding, but this association cannot be explained by decreased dental care.     

Pattern and severity of early childhood caries

OBJECTIVES: The aim of this study was to investigate the association between selected social and behavioural variables and the pattern and severity of early childhood caries (ECC) within a community child population. METHODS: A cross-sectional sample of 2515 children aged 4-5 years were examined in a preschool setting using decayed, missing, filled teeth/surface (dmft/dmfs) indices and a self-administered questionnaire was used to obtain information regarding social, demographic, birth, infant feeding, oral and general health attitudes. Children with caries (847) were divided into anterior or posterior caries pattern groups and severe (dmfs score > or =6) or non-severe (dmfs score <6) caries groups. The data were analysed using a chi-square test and modelled using a logistic regression procedure. RESULTS: Significant variables associated with anterior ECC pattern were ethnicity other than Caucasian (OR = 2.1, 95% CI = 1.4-3.1), sipping from the bottle during the day (OR = 1.9, 95% CI = 1.3-2.7), male gender (OR = 1.6, 95% CI = 1.2-2.2) and sleeping with a bottle at night (OR = 1.5, 95% CI = 1.1-2.2). Significant variables associated with severe ECC form were sipping from the bottle during the day (OR = 2, 95% CI = 1.4-2.8), maternal age at birth < or =24 years (OR = 1.8, 95% CI = 1.3-2.7), ethnicity other than Caucasian (OR = 1.6, 95% CI = 1.1-2.5) and sleeping with a bottle at night (OR = 1.5, 95% CI = 1.1-2.2). CONCLUSIONS: Infant bottle-feeding habits (either allowing a child to sip from a bottle during the day or put to sleep at night) and ethnicity other than Caucasian were significant determinants for both anterior caries pattern and severity of ECC in 4-5-year-old Australian children.     

Contribution of preventive methods in controlling caries among Saudi primary schoolchildren: a population-based cross-sectional study

Objective: This study assessed the association between caries preventive measures including regular dental checkups, twice a day tooth brushing using fluoridated toothpaste and pit and fissure sealants on one side and the presence of caries among primary schoolchildren in the Eastern Province of Saudi Arabia.

Materials and methods: A cross-sectional study was conducted in 2016 including 1198, 6–12-year-old children from 13 randomly selected schools. The outcome variable was caries presence. The explanatory variables were brushing twice a day using fluoridated toothpaste, the presence of sealant and regular dental checkups. Multivariable logistic regression model was conducted to assess the associations controlling for confounders (age, gender, ability to get treatment, being health insured and school) using SPSS version 20.0.

Results: Data of 921 participants (83.8%) were available. The prevalence of caries was 63.5%, whereas 67.6% brushed their teeth twice a day, 28.3% visited the dentist for regular checkups and 7.6% had sealant. In multivariable regression, out of the three main explanatory variables, only having regular checkups was significantly associated with caries presence (OR?=?0.65, 95% CI?=?0.48, 0.88).

Conclusions: Lower odds of caries presence were associated with regular dental checkups but not with regular brushing or having sealant.     

Multilevel assessment of determinants of dental caries experience in Brazil

OBJECTIVE: To examine contextual and individual determinants of dental caries experience, documenting levels of the disease in Brazil. METHODS: The dental status of 34 550 12-year-old schoolchildren was informed by a country-wide survey of oral health comprising 250 towns and performed in 2002-2003. Indices assessing dental caries experience were compared by sociodemographic characteristics of examined children (gender, ethnic group, localization and type of school), and geographic characteristics of participating towns [the human development index (HDI), and access to fluoridated tap water]. A multilevel model fitted the adjustment of untreated caries to individual and contextual covariates. RESULTS: Better-off Brazilian regions presented an improved profile of dental health, besides having a less unequal distribution of restorative dental treatments between blacks and whites, rural and urban areas, and public and private schools. Girls [odds ratio (OR)=1.1; 95% confidence interval (CI): 1.0-1.1], blacks (OR=1.6; 95% CI: 1.5-1.7), and children studying in rural areas (OR=1.9; 95% CI: 1.7-2.0) and public schools (OR=1.7; 95% CI: 1.6-1.9) presented higher odds of having untreated decayed teeth. The multilevel model identified the fluoride status of tap water (beta=-0.3), the proportion of households linked to the water network (beta=-0.3), and the HDI (beta=-0.2), as town-level variables associated with caries levels. CONCLUSION: Dental caries experience is prone to sociodemographic and geographic inequalities. The monitoring of contrasts in dental health outcomes is relevant for programming socially appropriate interventions aimed both at overall improvements and at the targeting of resources for groups of population presenting higher levels of needs.     

Oral Health Knowledge and Habits of Senior Elementary School Students

Despite improvements in children's dental health, and significant resource allocation to health education programs, few recent studies have investigated the associations of oral health knowledge, behaviors, and status. This study of 11-year-old children (N = 6,329) in northeastern Ontario used a supervised self-complete questionnaire and a clinical examination to gather baseline data on, and test associations of, caries and periodontal knowledge, self-reported oral health behaviors and source of knowledge, and oral health status. Results show the children had poor knowledge of caries preventive measures such as water fluoridation, dental sealants, and choice of snack foods. Periodontal knowledge was better, but children confused plaque and calculus. Respondents claimed good oral health habits, with 73 percent claiming to brush at least twice daily, 88 percent claiming to use toothpaste, 42 percent claim to floss at least twice weekly, and 84 percent claiming an annual dental visit. Children with the best knowledge claimed dentist and school as the sources. High knowledge was associated with good oral health habits (P less than .001) and low DMFT score (P less than .001). Good habits were not related to DMFT score (P = .1095). Logistic regression showed high knowledge was associated with English cultural status, urban school area, good habits, having a dental sealant, and attending a fluoride-rinse school (P less than .05). Findings suggest a need to reinforce caries preventive teaching, to investigate the effect of cultural status, dental experience, and residence status on oral health knowledge, and to further test the efficacy of different oral health education programs delivered by different sources.     

Prevalence and correlates of traumatic injuries to the permanent teeth of school-children aged 9–14 years in Belo Horizonte, Brazil

Abstract – A cross-sectional survey was carried out on 3702 boys and girls aged 9–14 years, attending public and private primary schools in Belo Horizonte, Brazil. A multi-stage sampling technique using an equal probability scheme was adopted to select the children. The response rate for the total sample was 97%. Dental examinations were carried out by one dentist (MISC). Intra-examiner agreement was very good. The prevalence of dental injuries increased from 8% at the age of 9 years to 13.6% at 12 and 16.1% at 14 years. Adjusted results showed that children from high socio-economic backgrounds were 1.4 (95% CI=1.15–1.79) times more likely to present with a dental injury than children with low SES. Boys were 1.7 times (95% CI=1.41–2.16) more likely to have dental injuries than girls. Children with an overjet size greater than 5.0 mm were 1.37 times (95% CI=1.06–1.80) more likely to have a dental injury than children with an overjet size equal or lower than 5.0 mm. Finally, children with an adequate lip coverage were 0.56 times (95% CI=0.44–0.72) less likely to have a traumatic dental injury than those with inadequate lip coverage.     

Who has difficulty in registering with an NHS dentist?--A national survey.

AIMS: The aims of this paper are first, to determine the extent of difficulties the public are experiencing in obtaining a dentist undertaking NHS dental care. Second, to describe the personal and socio-demographic details of these groups using data from a national study. METHOD: The vehicle for this study was the Office for National Statistics Omnibus Surveys, undertaken in June and July of 1999. A random probability sample of 5,385 addresses was selected from the British Postcode Address File. Respondents were interviewed in their homes about how difficult they found it to obtain an NHS dentist. RESULT: A total of 3,739 adults took part in this study and the response rate was 69%. Nineteen per cent (705) claimed they found it difficult to get an NHS dentist. Bivariate analysis revealed that difficulty in obtaining an NHS dentist [excluding those who claimed they did not seek NHS dental care (781) and those who refused to answer or did not know (66)] was associated with age group (P < 0.01), gender (P < 0.05), social class (P < 0.01) and area of residency (P < 0.01). Moreover, difficulty in obtaining NHS dental care was also associated with time since last dental visit (P < 0.01), method of payment for last dental visit (P < 0.01) and use of 'out of hours' emergency dental services (P < 0.01). Further analysis revealed that among the socio-demographic variables, area of residency emerged as the most important factor in determining difficulty in obtaining an NHS dentist. Those who lived in the South of England (London, South-East or South West) were more than twice as likely to experience difficulty in obtaining an NHS dentist, OR = 2.40, 95% CI 2.00-2.88 compared with those who lived elsewhere in Great Britain. CONCLUSION: One in five adults in Britain claim that they are experiencing difficulties in finding a dentist who will provide NHS dental care. In particular, those using private dental services and residents of the South of England have experienced such difficulties.     

Caries in five-year-old children and associations with family-related factors

It is generally understood that the teeth of pre-school-aged children are healthy, but the improvement in the dmft index has halted in the industrialized countries. Those few children who have caries have more of it than before. Little is known of the family-related factors which are associated with this polarization of caries. A representative population-based sample consisted of 1443 mothers expecting their first child. The children were followed at well-baby clinics and public dental health clinics for over five years. The objective was to study the prevalence of dental caries and its predictors in five-year-old children and to assess children's own dental health habits and the meaning of family-related factors in dental health. The findings were based on questionnaire data from parents and on clinical dental examinations of the five-year-old children as completed by 101 public health dentists. In firstborn five-year-old children, dental health was found to be good in 72%, fair in 20%, and poor in 8% of the cases. The final multivariate analysis illustrated that the dmft index > 0 was independently associated with the mother's irregular toothbrushing (OR 2.2; 95% CI 1.4-3.5), annual occurrence of several carious teeth in the father (OR 2.6; 95% CI 1.9-3.6), daily sugar consumption at the age of 18 months (OR 2.4; 95% CI 1.4-4.1), occurrence of child's headaches (OR 3.7; 95% CI 1.5-8.8), parents' cohabitation (OR 3.3; 95% CI 1.5-7.6), rural domicile (OR 2.4; 95% CI 1.2-4.5), and mother's young age (OR 5.0; 95% CI 1.3-19.8). The findings indicated that attention should be paid not only to the child's dental health care but also to that of the whole family. Parents should be supported in their upbringing efforts and encouraged to improve their children's dental health habits. In everyday life, parents function as role models for their children, and therefore, parents' own dental hygiene habits are very meaningful.
