The impact of a prospective 4-year longitudinal school intervention for improving oral health and oral health inequalities in primary schoolchildren in Flanders-Belgium.

BACKGROUND: Oral diseases and socio-economic inequalities in children are a persisting problem. AIM: To investigate the 4-year longitudinal impact of an oral health promotion programme on oral health, knowledge, and socio-economic inequalities in primary schoolchildren. DESIGN: The intervention was carried out between 2010 and 2014 within a random sample of Flemish primary schoolchildren (born in 2002). It consisted of an annual oral health education session. ICDAS/DMFT, care level, knowledge scores, and plaque index were used as outcome variables. Being entitled to a corrective policy measure was used as social indicator. Mixed model analyses were conducted to evaluate changes over time between intervention and control group and between higher and lower social subgroups. RESULTS: A total of 1058 participants (23.8%) attended all four sessions. The intervention had a stabilizing effect on the number of decayed teeth and increased knowledge scores. No statistically different effect on the two social groups could be demonstrated. Socio-economic inequalities were present both at T0 and T4 . CONCLUSION: The oral health promotion programme had a positive impact on oral health knowledge and stabilized the number of decayed teeth. No impact on inequalities could be demonstrated, although a higher dropout rate in children with a lower social status was seen.

Dental caries and periodontal diseases in the ageing population: call to action to protect and enhance oral health and well-being as an essential component of healthy ageing - Consensus report of group 4 of the joint EFP/ORCA workshop on the boundaries between caries and periodontal diseases.

BACKGROUND: Over the last two decades, progress in prevention and treatment of caries and periodontal diseases has been translated to better oral health and improved tooth retention in the adult population. The ageing population and the increasing expectations of good oral health-related quality of life in older age pose formidable challenges to clinical care and healthcare systems. AIMS: The objective of this workshop was to critically review scientific evidence and develop specific recommendations to: (i) prevent tooth loss and retain oral function through prevention and treatment of caries and periodontal diseases later in life and (ii) increase awareness of the health benefits of oral health as an essential component of healthy ageing. METHODS: Discussions were initiated by three systematic reviews covering aspects of epidemiology of caries and periodontal diseases in elders, the impact of senescence on caries and periodontal diseases and the effectiveness of interventions. Recommendations were developed based on evidence from the systematic reviews and expert opinion. RESULTS: Key messages included: (i) the ageing population, trends in risk factors and improved tooth retention point towards an expected increase in the total burden of disease posed by caries and periodontal diseases in the older population; (ii) specific surveillance is required to monitor changes in oral health in the older population; (iii) senescence impacts oral health including periodontitis and possibly caries susceptibility; (iv) evidence indicates that caries and periodontal diseases can be prevented and treated also in older adults; (v) oral health and functional tooth retention later in life provides benefits both in terms of oral and general quality of life and in terms of preventing physical decline and dependency by fostering a healthy diet; (vi) oral healthcare professionals and individuals should not base decisions impacting tooth retention on chronological age but on level of dependency, life expectancy, frailty, comfort and quality of life; and (vii) health policy should remove barriers to oral health care for vulnerable elders. CONCLUSIONS: Consensus was reached on specific actionable priorities for public health officials, oral healthcare professionals, educators and workforce planners, caregivers and relatives as well as for the public and ageing patients. Some priorities have major implications for policymakers as health systems need to adapt to the challenge by systemwide changes to enable (promote) tooth retention later in life and management of deteriorating oral health in increasingly dependent elders.

Higher education in Gerodontology in European Universities.

BACKGROUND: The rapid aging of the European population and the subsequent increase in the oral care needs in older adults necessitates adequate training of dental professionals in Gerodontology (Geriatric Dentistry). This study was designed to investigate the current status of Gerodontology teaching amongst European dental schools at the undergraduate, postgraduate and continuing education levels. METHODS: An electronic questionnaire was developed by a panel of experts and emailed to the Deans or other contact persons of 216 dental schools across 39 European countries. The questionnaire recorded activity levels, contents and methodology of Gerodontology teaching as part of dental education programs. Repeated e-mail reminders and telephone calls were used to encourage non-responders to complete the questionnaire. RESULTS: A total of 123 responses from 29 countries were received (response rate: 56.9%). Gerodontology was taught in 86.2% of schools at the undergraduate level, in 30.9% at the postgraduate level and in 30.1% at the continuing education level. A total of 43.9% of the responding schools had a dedicated Gerodontology program director. Gerodontology was taught as an independent subject in 37.4% of the respondent schools. Medical problems in old age, salivary impairment and prosthodontic management were the most commonly covered topics in Gerodontology teaching. Clinical teaching took place in 64.2% of the respondent schools, with 26.8% offering clinical training in outreach facilities. CONCLUSIONS: The vast majority of European dental schools currently teach Gerodontology at the undergraduate level. More training opportunities in oral care of frail elders should be offered, and more emphasis should be placed on interdisciplinary and interprofessional training, educational collaborations, and the use of modern technologies. Dedicated postgraduate Gerodontology courses need to be developed to create a significant number of specialized dentists and trained academics.

An oral health survey of vulnerable older people in Belgium.

OBJECTIVES: The aim of this study was to gain insight in the oral health of persons aged 65 years or more. MATERIALS AND METHODS: Data were obtained from 652 vulnerable older persons (≥65) by means of a clinical oral examination. Additional demographic data were gathered including age, gender, residence, and care dependency. RESULTS: The mean age of the total study sample was 83 (7.7) years and 71 % was female. Nearly 33 % of the sample was living at home with support, and 67 % was residing in nursing homes. The number of occluding pairs was low and the proportion of edentulous people was highest among persons with the highest care dependency. The mean Decay-missing-filled teeth index (DMFT) was 20.3 (9.0). A prosthetic treatment need and inadequate oral hygiene levels were observed in 40 % and more than 60 % of the subjects, respectively. The highest treatment need was observed in the oldest age group and the highest mean dental plaque in older persons with the highest care dependency. CONCLUSIONS: The oral health in frail older people in Belgium is poor. The restorative and prosthetic treatment need is high and oral hygiene levels are problematic. Age, residence, and care dependency seemed to have some influence on oral health parameters. CLINICAL SIGNIFICANCE: In the long term, the most important future challenge of oral health care policies is to identify older adults before they begin to manifest such oral health deterioration. Regular dental visits should be strongly promoted by all (oral) health care workers during the lifespan of all persons including older adults.

Effect of an oral healthcare protocol in nursing homes on care staffs' knowledge and attitude towards oral health care: a cluster-randomised controlled trial.

OBJECTIVE: To explore the impact of a supervised implementation of an oral healthcare protocol, in addition to education, on nurses' and nurses' aides' oral health-related knowledge and attitude. MATERIALS AND METHODS: A random sample of 12 nursing homes, accommodating a total of 120-150 residents, was obtained using stratified cluster sampling with replacement. The intervention included the implementation of an oral healthcare protocol and three different educational stages. One of the investigators supervised the implementation process, supported by a dental hygienist. A 34-item questionnaire was developed and validated to evaluate the knowledge and attitude of nurses and nurses' aides at baseline and 6 months after the start of the intervention. Linear mixed-model analyses were performed to explore differences in knowledge and attitude at 6 months after implementation. RESULTS: At baseline, no significant differences were observed between the intervention and the control group for both knowledge (p = 0.42) and attitude (p = 0.37). Six months after the start of the intervention, significant differences were found between the intervention and the control group for the variable knowledge in favour of the intervention group (p < 0.0001) but not for the variable attitude (p = 0.78). Out of the mixed model with attitude as the dependent variable, it can be concluded that age (p = 0.031), educational level (p = 0.009) and ward type (p = 0.014) have a significant effect. The mixed model with knowledge as the dependent variable resulted in a significant effect of the intervention (p = 0.001) and the educational level (p = 0.009). CONCLUSION: The supervised implementation of an oral healthcare protocol significantly increased the knowledge of nurses and nurses' aides. In contrast, no significant improvements could be demonstrated in attitude.

Opinions of dentists on the barriers in providing oral health care to community-dwelling frail older people: a questionnaire survey.

OBJECTIVE: The aim of this study was to investigate to what extent dentists in the Netherlands experience barriers in providing oral health care to community-dwelling older people. BACKGROUND: As most publications on the barriers in providing oral health care to older people consist of surveys on oral health care in care homes, it was decided to investigate the barriers dentists experience in their own dental practices while providing oral health care to community-dwelling frail older people. MATERIAL AND METHODS: A representative sample of 1592 of the approximately 8000 dentists in the Netherlands aged 64 or younger were invited to respond to a questionnaire online. The dentists were asked to respond to 15 opinions concerning oral healthcare provision to community-dwelling frail older people aged 75 years or more who experience problems in physical, psychological and social areas, as well as possible financial problems. RESULTS: The total response rate was 37% (n = 595; male=76%; average age 49). The majority of those who responded agreed that the reimbursement of oral health care to older people is poor. Two thirds of those who responded (66%) agreed that there are limited opportunities to refer the frail and elderly with complex oral healthcare problems to a colleague with specific knowledge and skills. CONCLUSION: Dentists experienced barriers in two domains; a lack of knowledge and practical circumstances. It was concluded that the dentist's gender, age, year of graduation and the number of patients aged 75 years or more treated weekly were in some respect, related to the barriers encountered.

The integration of oral health care into day-to-day care in nursing homes: a qualitative study.

OBJECTIVE: This qualitative study explored barriers and enabling factors to the implementation of an oral hygiene protocol in nursing homes. BACKGROUND: Oral health care in nursing homes in Flanders (Belgium) is inadequate. MATERIALS AND METHODS: Qualitative data were obtained from nurses employed in 13 nursing homes involved in two randomised controlled trials in Flanders-Belgium. Data were collected by focus group and face-to-face interviews during April 2005 and December 2009. All transcripts were analysed with support of NVivo 8 (Version 2008). Transcripts were intuitively analysed in a two-step method. RESULTS: Most revealed barriers were consistent with previous findings in the literature. Newly reported barriers were respect for residents' self-determination, experience based oral health care by nurses, residents' oral health status and nurses' inability to notice residents' oral health status. Demand-driven oral health care was found to be a strong enabling factor. CONCLUSION: The integration of oral health care into day-to-day care seems to be a major problem due to a multitude of barriers. In future implementation innovations in oral health care an a priori assessment of influencing factors is recommended.

Effectiveness of supervised implementation of an oral health care guideline in care homes; a single-blinded cluster randomized controlled trial.

OBJECTIVES: The objective of this study was to assess the effectiveness of a supervised implementation of the "Oral health care Guideline for Older people in Long-term care Institutions" (OGOLI) in The Netherlands. MATERIALS AND METHODS: A sample of 12 care homes in the Netherlands was allocated randomly to an intervention or control group. While the residents in the control group received oral health care as before, the intervention consisted of a supervised implementation of the OGOLI. RESULTS: At baseline, the overall random sample comprised 342 residents, 52 % in the intervention group and 48 % in the control group. At 6 months, significant differences were observed between the intervention and the control group for mean dental as well as denture plaque, with a beneficial effect for the intervention group. The multilevel mixed-model analyses conducted with the plaque scores at 6 months as outcome variables showed that the reduction by the intervention was only significant for denture plaque. CONCLUSIONS: Supervised implementation of the OGOLI was more effective than non-supervised implementation in terms of reducing mean plaque scores at 6 months. However, the multilevel mixed-model analysis could not exclusively explain the reduction of mean dental plaque scores by the intervention. CLINICAL RELEVANCE: A supervised implementation of an oral health care guideline improves oral health of care home residents.

Effect evaluation of a supervised versus non-supervised implementation of an oral health care guideline in nursing homes: a cluster randomised controlled clinical trial.

OBJECTIVE: To compare a supervised versus a non-supervised implementation of an oral health care guideline in Flanders (Belgium). BACKGROUND: The key factor in realising good oral health is daily oral hygiene care. In 2007, the Dutch guideline 'Oral health care in care homes for elderly people' was developed to improve oral health of institutionalised elderly. MATERIALS AND METHODS: A random sample of 12 nursing homes was randomly allocated to the intervention or the control group. Representative samples of 30 residents in each home were monitored during a 6-month study period. The intervention included a supervised implementation of the guideline. RESULTS: At the 6-month follow-up, only a small but statistically significant (p = 0.002) beneficial effect (0.32) of the intervention was observed for denture plaque after adjustment for baseline value and the random effect of the institution. In the linear mixed regression models, including a random institution effect, difference in denture plaque level was no longer statistically significant at the 5% level. CONCLUSION: Only denture hygiene has been improved by the supervised implementation, although with lower benefits than presumed. Factors on institutional level, difficult to assess quantitatively, may play an important role in the final result.

An oral health care guideline for institutionalised older people.

Institutionalized older people are prone to oral health problems and their negative impact due to frailty, disabilities, multi-morbidity, and multiple medication use. Until recently, no evidence-based oral health care guideline for institutionalized older people has been available. For that reason, the Dutch Association of Nursing Home Physicians developed the Oral health care Guideline for Older people in Long-term care Institutions (OGOLI), meeting the requirements of the AGREE instrument for assessing a guideline's quality. This short report presents the keynotes and the content of the Oral health care Guideline. Most recommendations are based on expert opinions. Only 4 recommendations (education, pneumonia, use of an electric toothbrush, and fluoride rinsing in case of a sudden increase of oral plaque amount) are based on evidence level A2 conclusions. This emphasizes the need for further research on oral health of institutionalized older people.

Supervised versus non-supervised implementation of an oral health care guideline in (residential) care homes: a cluster randomized controlled clinical trial.

BACKGROUND: The increase of the proportion of elderly people has implications for health care services. Advances in oral health care and treatment have resulted in a reduced number of edentulous individuals. An increasing number of dentate elderly people have tooth wear, periodontal disease, oral implants, and sophisticated restorations and prostheses. Hence, they are in need of both preventive and curative oral health care continuously. Weakened oral health due to neglect of self care and professional care and due to reduced oral health care utilization is already present when elderly people are still community-dwelling. At the moment of (residential) care home admittance, many elderly people are in need of oral health care urgently. The key factor in realizing and maintaining good oral health is daily oral hygiene care. For proper daily oral hygiene care, many residents are dependent on nurses and nurse aides. In 2007, the Dutch guideline "Oral health care in (residential) care homes for elderly people" was developed. Previous implementation research studies have revealed that implementation of a guideline is very complicated. The overall aim of this study is to compare a supervised versus a non-supervised implementation of the guideline in The Netherlands and Flanders (Belgium). METHODS/DESIGN: The study is a cluster randomized intervention trial with an institution as unit of randomization. A random sample of 12 (residential) care homes accommodating somatic as well as psycho-geriatric residents in The Netherlands as well as in Flanders (Belgium) are randomly allocated to an intervention or control group. Representative samples of 30 residents in each of the 24 (residential) care homes are monitored during a 6-months period. The intervention consists of supervised implementation of the guideline and a daily oral health care protocol. Primary outcome variable is the oral hygiene level of the participating residents. To determine the stimulating or inhibiting factors of the implementation project and the nurses' and nurse aides' compliance and perceived barriers, a process evaluation is carried out. DISCUSSION: The method of cluster randomization may result in a random effect and cluster selection bias, which has to be taken into account when analyzing and interpreting the results. TRIAL REGISTRATION: Current Controlled Trials ISRCTN86156614.

European College of Gerodontology: undergraduate curriculum guidelines in gerodontology.

Effective undergraduate teaching of gerodontology to present and future dental students is important if good oral health care of older people is to be assured. A review of the undergraduate curriculum for gerodontology is presented and indicates the need for a knowledge base from which new graduates can develop a special interest in care of older patients. The aim is improved care of older patients, satisfaction for teaching staff involved and improved professional standing for Dentistry. Motivation of students could also be achieved by the positive match between rising patient awareness and ethical responsibility of the profession for those older patients. As it stands, the undergraduate curriculum should include topics on specific care for the elderly and other patient groups, which extend the competences already agreed by the Association for Dental Education in Europe (ADEE). The logistics of teaching these topics will need co-ordination of those staff with appropriate skill and interest, preferably as a development of existing curriculum content.

Oral health and healthcare utilization in Belgian dentate adults.

OBJECTIVES: In 2012-2014, the Belgian National Oral Health Data Registration and Evaluation Survey, integrated in the Health Interview Survey (HIS), was carried out. The present study investigated, in a sample of 1340 dentate adults (≥25 years), the association between oral healthcare utilization, oral health status and sociodemographic status. METHODS: A multistage, stratified cluster sampling procedure was used. Oral examination for caries experience (World Health Organization, D3 MFT-Index), periodontal status (Dutch Periodontal Screening Index, DPS-Index), number of teeth present and occlusal contacts without wearing removable dentures was performed by calibrated examiners. Oral healthcare utilization data were retrieved from the records of the Belgian Intermutualistic Agency. Participants' oral health and sociodemographic data were linked to registered oral care utilization in the previous 5-year period. Regular attenders (annual attenders and those with at least one registered contact in three different years) were compared with irregular attenders (those having had dental visits but not according to the definition of regular attenders) and nonattenders. Data were weighted to compensate for sampling and participation bias. RESULTS: Six hundred and seventy-nine participants attended regularly, of whom 276 annually; 256 did not attend in the reference period. The overall D3 MFT-Index was not noticeably different between attendance patterns (varying between 11 and 13), although regular attenders had more restored teeth than nonattenders (P < 0.01). No difference was seen for DPS-Index and number of teeth/occluding pairs (χ2 test, P > 0.05). Females, participants with higher education, older participants and those in employment had higher rates of regular attendance. CONCLUSIONS: Regular attenders had fewer untreated caries lesions, but neither lower caries experience nor lower DPS-Index than irregular attenders. Regular attendance was associated with sociodemographic variables.

The impact of a preventive and curative oral healthcare program on the prevalence and incidence of oral health problems in nursing home residents.

AIMS: To assess the impact of an oral healthcare program in nursing homes on the initial treatment backlog and residents' oral health stability. MATERIALS AND METHODS: The study is a longitudinal cohort study in nursing home residents in Flanders, Belgium, to evaluate the oral healthcare programme Gerodent. The program consisted of: (1) the introduction of an oral healthcare team, (2) oral health education, (3) the implementation of oral health guidelines and protocols, and (4) regular visits of a mobile dental team. Data were extracted from the oral health records of 381 residents from 21 nursing homes who received treatments from the mobile dental team between October 2010 and March 2014 (mean follow-up period of 22.5 months). Oral health and treatment need between baseline and follow-up were compared. RESULTS: The mean age at baseline was 82.4 years and the mean number of consultations per resident was 3.61 during the follow-up period. The proportion of residents with an oral treatment need was reduced from 65.9% to 31.3%. Among residents with natural teeth, there was significantly lower prevalence of caries (from 70.5% at baseline to 36.5% at follow-up; p<0.001), residual roots (from 54.2% to 25.1%; p<0.001), and need for fillings (from 31.9% to 17.1%; p<0.001) or extractions (from 64.3% to 31.6%; p<0.001). In the group with partial or full dentures (n = 223), 38.1% needed a repair, rebasing or renewal of their existing dentures at baseline and the respective figure at follow-up was 9.0% (p<0.001). In terms of oral health stability, 53% of the residents had no incident restorative and prosthetic treatment need throughout the follow-up period. A lower number of natural teeth at baseline (p<0.001) and a shorter follow-up period (p = 0.002) were associated with higher chances of oral health stability. CONCLUSION: The oral healthcare program Gerodent significantly reduced the treatment backlog and contributed to a considerable proportion of residents being stable in terms of oral health without any incident treatment needs.

An Expert Opinion from the European College of Gerodontology and the European Geriatric Medicine Society: European Policy Recommendations on Oral Health in Older Adults.

This is an expert opinion paper on oral health policy recommendations for older adults in Europe, with particular focus on frail and care-dependent persons, that the European College of Gerodontology (ECG) and the European Geriatric Medicine Society (EUGMS) Task and Finish Group on Gerodontology has developed. Oral health in older adults is often poor. Common oral diseases such as caries, periodontal disease, denture-related conditions, hyposalivation, and oral pre- and cancerous conditions may lead to tooth loss, pain, local and systemic infection, impaired oral function, and poor quality of life. Although the majority of oral diseases can be prevented or treated, oral problems in older adults remain prevalent and largely underdiagnosed, because frail persons often do not receive routine dental care, due to a number of barriers and misconceptions. These hindrances include person-related issues, lack of professional support, and lack of effective oral health policies. Three major areas for action are identified: education for healthcare providers, health policy action plans, and citizen empowerment and involvement. A list of defined competencies in geriatric oral health for non-dental healthcare providers is suggested, as well as an oral health promotion and disease prevention protocol for residents in institutional settings. Oral health assessment should be incorporated into general health assessments, oral health care should be integrated into public healthcare coverage, and access to dental care should be ensured.

Practical Guidelines for Physicians in Promoting Oral Health in Frail Older Adults.

Good oral health in old age is particularly important for maintaining adequate oral function, preventing pain and discomfort, controlling localized or systemic inflammation, sustaining social interaction, and preserving quality of life. Given that oral health is an integral part of general health and well-being, and that major chronic systemic and oral diseases share common risk factors, oral health prevention and promotion should be embedded within routine medical assessment and care provision. The role of medical physicians, particularly primary care physicians, geriatricians, and elderly care physicians, in community and long-term care facilities in assessing and promoting oral health in frail older adults is critical and has been emphasized in recent European recommendations. All physicians should appreciate the importance of oral health and incorporate an initial oral health screening into routine medical assessment and care. A short interview with patients and carers on current oral health practices may help to assess the risk for rapid oral health deterioration. The interview should be followed by an oral health assessment, using validated tools, for nondental health care providers. Based on these findings, the physician should decide on necessary follow-up procedures, which may include oral health counseling and/or dental referral. Oral health counseling should include advice on daily oral, mucosal, and denture hygiene; denture maintenance; dietary advice; smoking cessation; limitation of harmful alcohol consumption; management of xerostomia; and frequent dental review. To enable physicians to perform the tasks recommended in this publication, appropriate teaching at both undergraduate and postgraduate levels must be delivered in addition to provision of appropriate continuing education courses.

Medication Use and Its Potential Impact on the Oral Health Status of Nursing Home Residents in Flanders (Belgium).

BACKGROUND: Polypharmacy is considered the most important etiologic factor of hyposalivation, which in turn can initiate oral health problems. OBJECTIVES: To describe the medication use of nursing home residents, to identify the medications related to hyposalivation and to find possible associations between the different classes of medication, the number of medications, and the oral health status of the residents. DESIGN: A cross-sectional study. PARTICIPANTS: The study population consisted of the residents of a nonrandom sample of 23 nursing homes from 2 Belgian provinces, belonging to the oral health care network Gerodent. All residents of the sample visited the Gerodent mobile dental clinic between October 2010 and April 2012. MEASUREMENTS: For each resident, oral health data, demographic data, and an overview of the total medication intake were collected. RESULTS: The study sample consisted of 1226 nursing home residents with a mean age of 83.9 years [standard deviation (SD) 8.5]. The mean number of medications per person was 9.0 (SD 3.6, range 0-23, median 9.0). Of all prescribed medication, 49.6% had a potential hyposalivatory effect with a mean number per person of 4.5 (SD 2.2, range 0-15, median 4.0). In the bivariate analyses, associations were found between medication use and oral health of residents with natural teeth: the higher the number of medications (with risk of dry mouth) and the overall risk of medication-related dry mouth, the lower the number of natural teeth (P = .022, P = .005, and P = .017, respectively). In contrast, the total treatment need tended to decrease with rising medication intake, resulting in a clear increase of the treatment index with rising medication intake (P = .003, P < .001 and P = .002). The logistic regression model analysis confirmed that the proportion of carious teeth diminished and the treatment index increased in case of rising medication intake, especially when considering the number of medications with a risk of dry mouth and the overall risk of medication-related dry mouth. A possible explanation for this trend might be the finding that in the group with a high medication use, the teeth most sensitive to caries and plaque retention could already have been extracted at the moment of screening for the study, because of a lifelong history of caries pathology. CONCLUSIONS: This study shows a high level of medication use, including the substantial intake of medication with a possible hyposalivatory effect. Moreover, clear associations were found between the medication intake and the oral status of the residents.

Socioeconomic inequalities in caries experience, care level and dental attendance in primary school children in Belgium: a cross-sectional survey.

OBJECTIVES: Oral health inequality in children is a widespread and well-documented problem in oral healthcare. However, objective and reliable methods to determine these inequalities in all oral health aspects, including both dental attendance and oral health, are rather scarce. AIMS: To explore oral health inequalities and to assess the impact of socioeconomic factors on oral health, oral health behaviour and dental compliance of primary school children. METHODS: Data collection was executed in 2014 within a sample of 2216 children in 105 primary schools in Flanders, by means of an oral examination and a validated questionnaire. Intermutual Agency database was consulted to objectively determine individuals' social state and frequency of utilisation of oral healthcare services. Underprivileged children were compared with more fortunate children for their mean DMFt, DMFs, plaque index, care index (C, restorative index (RI), treatment index (TI), knowledge and attitude. Differences in proportions for dichotomous variables (RI100%, TI100% and being a regular dental attender) were analysed. The present study was approved by the Ethics Committee of the University Hospital Ghent (2010/061). All parents signed an informed consent form prior to data collection. All schools received information about the study protocol and agreed to participate. Children requiring dental treatment or periodic recall were referred to the local dentist. RESULTS: Underprivileged children had higher D1MFT (95% CI 0.87 to 1.36), D3MT (95% CI 0.30 to 0.64), plaque scores (95% CI 0.12 to 0.23) and lower care level (p<0.02). In the low-income group, 78.4% was caries-free, compared with 88.4% for the other children. Half of the low-income children could be considered as regular dental attenders, while 12.6% did not have any dental visit during a 5-year period. CONCLUSION: Oral health, oral hygiene, oral healthcare level and dental attendance patterns are negatively affected by children's social class, leading to oral health inequalities in Belgian primary school children.

Tooth brushing and social characteristics of families in 32 countries.

OBJECTIVES: To compare the reported tooth brushing behaviour among adolescents in relation to age, gender and parental occupation, family affluence, single parent family and at least one parent not working but staying at home. METHODS: Representative samples of 11-, 13- and 15 year old pupils in 32 countries completed an anonymous standardised questionnaire during school hours. RESULTS: Large differences in prevalences of reported tooth brushing were found between countries for both genders: from 16-80 % for boys and 26-89% for girls. In some countries the prevalence of more-than-once-a-day tooth brushing increased by increasing age, whereas in others it declined. High occupational status and family affluence were clearly related to a high prevalence of more-than-once-a-day tooth brushing. Children living in two parent families had higher prevalences of recommended tooth brushing in only a few countries. CONCLUSIONS: Within the European continent and in North America, gender, family affluence and parental occupation were significantly associated with reported tooth brushing frequency among adolescents. The association between family characteristics, such as absence of one of the parents and the supervisory role of the parents, and brushing behaviour of the children appeared to be rather weak and inconsistent.

Determinants of early childhood caries in a group of inner-city children.

OBJECTIVE: This study aimed to determine the prevalence of early childhood caries (ECC) and severe early childhood caries (s-ECC) in inner-city children in Ghent, Belgium, and to investigate the independent impact of its determinants. METHOD AND MATERIALS: In a non-randomized cross-sectional research design, all children between 24 and 34 months of age attending the final consultation at a participating Child and Family Health Clinic were included (n = 385). Data on oral hygiene and caries were collected by oral examination. Caries prevalence and oral hygiene were determined according to established criteria. Data on oral health habits and socioeconomic status were obtained by a validated questionnaire. All analyses were performed with ECC and s-ECC as response variables. RESULTS: The mean DMFS was 0.83 (SEM = 0.14). ECC was diagnosed in 18.5% of the children and s-ECC was found in 12.2%. Treatment need was 100%. From the multiple regression analysis it became clear that ethnicity and neighborhood significantly determined ECC. From all oral health-related behavioral variables, only daily use of a bottle with sweetened drinks other than milk or water, frequency of brushing, and quality of oral hygiene as expressed by Plaque Index scores remained significantly associated with ECC. CONCLUSION: Children whose mothers had an Eastern European nationality at birth and who live in a deprived neighborhood, daily use a bottle with sweetened drinks other than milk or water, brush less than once a day, and have plaque are at higher risk for ECC and s-ECC.
