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. 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. 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. 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.

The aim of this study was to gain insight in the oral health of persons aged 65 years or more. 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. 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. 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. 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.

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).

The present study aimed to explore the association between caries risk profiles and different sociodemographic factors . The study sample () was randomly selected within an urban population in Flanders, Belgium. Caries risk was assessed by anamnesis, clinical examination, salivary tests, and a questionnaire. Age, gender, and socio-economic status were extracted from social insurance data files. Social indicators were “occupational status,” “being entitled to the increased allowance for health care interventions” and having access to the “Maximum Bill” (MAF), initiatives undertaken to protect deprived families. In the bivariate analysis there were significant differences in risk profiles between occupational groups (), between entitled and non-entitled individuals to the increased allowance (), and between access or no-access to the MAF (). The multiple logistic model showed a significantly higher chance of being in the low risk group for individuals with no-access to the MAF compared to those with access (OR:14.33–95% C.I. 2.14–95.84).

Objective:  The aim of the study was to assess the dental students’ attitude towards tobacco cessation counselling in the dental setting and to explore the influence of knowledge, belief in effectiveness, smoking status, gender and curriculum.Material and methods:  The study group consisted of all undergraduate students from the 2002–2003 classes of the Ghent University (n = 96). A validated questionnaire was administered to all students involving four different sections: demographic characteristics, attitude related to tobacco cessation programmes in the dental setting, belief in their effectiveness and knowledge concerning tobacco health effects. Statistical analysis included simple univariate nonparametric tests for evaluating differences in attitude towards tobacco cessation programmes, belief in effectiveness of tobacco cessation programmes in the dental setting and knowledge of students concerning tobacco health effects by year of graduation, smoking status and gender. Multiple logistic regression was chosen to calculate adjusted odds ratios and 95% confidence intervals.Results:  Students view willingness to advise individual patients to quit using tobacco. Yet only 51.3% are willing to co‐operate in anti‐tobacco programmes at the community level, and the perception of students of the effectiveness of smoking cessation counselling in the dental setting is low. The variance of attitude towards tobacco cessation programmes was significantly affected by knowledge and the belief in effectiveness of tobacco cessation programmes in the dental setting. Better knowledge and belief in effectiveness of tobacco cessation counselling was associated with an increasing positive attitude towards tobacco cessation programmes expressed by an odds ratio of 3.12 (95% CI 1.00–9.67) and 1.17 (95% CI 1.00–1.37) respectively.Conclusion:  Belief in effectiveness and knowledge seem to influence the attitude of students towards tobacco cessation counselling.Practice implications:  Besides imparting knowledge, the attitude of newly graduated dentists could be improved by stressing the effectiveness of smoking cessation activities during lectures and integrated training modules in the undergraduate education.

This study aimed to contribute to the descriptive information of oral health status in the primary dentition, especially concerning the distribution and spatial correlation of lesions. Data were obtained from two surveys. In the Signal-Tandmobiel® project 4,468 7-year-old children in Flanders (Belgium) were selected by a stratified clustered random sample. In the Tandje de Voorste – Smile for Life (TDV) project, data were obtained from 1,291 3-year-old and 1,315 5-year-old children. The children were examined by trained dentists, using standardized and widely accepted criteria, based on the British Association for the Study of Community Dentistry criteria. At the population level, symmetry in the prevalence of caries experience across the midline was tested at the tooth and tooth surface levels using generalized estimating equations and alternating logistic regression (ALR) approaches. Individual symmetry was tested using an approach described by Hujoel et al. [J Dent Res 1994;73:1575–1580]. Descriptive observations suggested a symmetrical distribution of caries experience at the population level. The null hypothesis of symmetry could not be rejected at a 0.05 level, suggesting that caries experience might be symmetric in the deciduous dentition. Based on the ALR approach, 2 × 2 associations of caries experience at the tooth and surface levels, both in 5- and 7-year-olds, appeared to be strongest for the left-right pairs in the mandible, followed by the left-right pairs in the maxilla. At the individual level the hypothesis of random caries pattern was rejected (p < 0.0001). In conclusion, at the population level the null hypothesis of left-right symmetry could not be rejected, while at the individual level lesions tended to cluster on one side of the mouth.

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. 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. 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. 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.

This study was designed to explore variations in oral hygiene practices and facilities in long-term care institutions for elders. Reported level of caregivers' knowledge related to oral health, reported work-climate, management, size of the institution and the mean age and degree of dependency of residents were evaluated. Sixteen nursing homes were selected, using stratified random sampling, in the region of Gent (Flanders). Nine different strata were used based on size and management. Factors thought to be associated with the variation in oral hygiene practices and facilities were collected from 225 caregivers (75%) through a structured 45-item questionnaire. The questionnaire was validated and tested for reliability during a test-retest prior to the start of the study. The relation between rates of oral hygiene practices and facilities and explanatory variables was investigated using correlation analysis and subsequently by multiple regression analysis. The best fitted regression model explained 30% of oral hygiene practice variation. The most predictive variable was the knowledge of caregivers, which explained 17% of the variation, while mean age explained 7% and managerial behaviour 6.3%. There was a trend towards a negative relationship with mean age, degree of dependency and size of the institution. Most of the variance in oral health practices and facilities in long-term care institutions for elders in Gent remains unexplained. Knowledge, mean age and managerial behaviour were the most likely explanatory variables.
