Dental caries affects three quarters of five-year old children in Northern Ireland. It should be seen as a priority target for health education and health promotion initiatives, argue Grainne Quinn and Ruth Freeman. A study to investigate co-operation between health visitors and community dental officers demonstrates the importance of the frequent sharing of knowledge and expertise between the two professionals in the promotion of dental health.

AIM: To test the effectiveness of dental health educators in general dental practice. OBJECTIVE: To evaluate the effectiveness and cost of primary care trusts seconding dental health educators free of charge to suitable general dental practices to provide dental health counselling to mothers of regularly attending pre-school children at risk to caries. METHOD: Two-cell, parallel group, cluster randomised, controlled clinical trial of two years' duration. CLINICAL SETTING: 30 general dental practices in North-West England. PARTICIPANTS: 269 mothers of 334 pre-school children. INTERVENTIONS: Those in the test group were given visits to a dental health educator over a 2-year period to counsel mothers of at-risk, pre-school children. The rest were held as a control. MAIN OUTCOME MEASURES: Caries prevalence of the children and dental health knowledge, attitudes and toothbrushing skills of the parents. The full costs of the exercise were kept throughout. The statistical analysis controlled for the clustering of children within practices. RESULTS: After 2 years, 271 (81%) children and 248 (92%) mothers remained in the study. There was an 18% difference in mean dmft between the groups in favour of the test group children but this was not statistically significant. At the end of the study there was an 18% difference in mean dmft between the groups in favour of the test group children but this was not statistically significant. No difference in plaque levels was found. The mothers in the test group were more knowledgeable, had better attitudes towards the dental health of their offspring and better toothbrushing skills than those in the control. Each 2-hour session to counsel ten parents cost pound 40. CONCLUSION: Primary care trusts should carefully consider the cost value of seconding dental health educators to counsel parents of regularly attending, at-risk, pre-school children when considering such an option.
The aim of the study was to evaluate the Lothian 1991 dental health campaigns on 5-year-old schoolchildren's oral hygiene and gingival health in relation to deprivation. A stratified random sample of 486 children was selected from 92 primary schools in the city of Edinburgh. Clinical examinations took place immediately before (T1), a month after (T2) and 4 months after the campaign (T3). A total of 342 (70 per cent) children received all 3 examinations. Oral hygiene and gingival health were examined using a modified Silness and Löe and the Ainamo and Bay Index. Toothbrushes and take-home materials were distributed to all children. Dental officers provided 20 minute information sessions for each class and encouraged teachers to continue dental health activities within the classes. For the purpose of the evaluation, schools were categorised as deprived and non-deprived according to established social indicators. The results showed a statistically significant improvement in plaque scores at T2 and T3 (P < 0.05, P < 0.01). Also gingival health improved at T2 and T3 (P < 0.01, P = 0.001). However, the improvements took place only in the non-deprived schools. Thirty-one per cent of children in non-deprived schools and 18 per cent in deprived schools had a total plaque score of 0 at T1 and 41 per cent and 19 per cent respectively at T3. The differences in gingival health scores between deprived and non-deprived schools were statistically significant at T2 and T3 but not at T1. The campaign was therefore successful when evaluating the population as a whole.(ABSTRACT TRUNCATED AT 250 WORDS)

Eighteen-hundred rural children ages five through thirteen were randomly assigned for dental treatment to a school-based practice, and to private practitioners in the community. Simultaneously, five of the nine public schools attended by the children offered an enriched program of dental education while the remaining schools taught the regular health education courses. All children participated in a school based fluoride program and their dental treatment was provided without charge. Data indicating how the children utilized dental services were collected over the three-year treatment phase of the study. Evidence from the third treatment year indicates that children assigned to the school based practice who also attended a school offering enriched dental health education used dental services on a more regular basis than children in the other three groups. Evidence obtained from log-linear modeling supports the hypothesis that dental health education had a positive effect on children's utilization of dental service.

Approximately 25--30 per cent of operational time in the School Dental Programme is assigned to dental health education, representing a sizeable investment of public resources. If the full potential of dental health education is to be realized, the respective effectiveness of various dental health education activities need to be identified so that the more effective activities can be emphasized and developed further. As an essential prerequisite there is a need to refine the evaluation process by introducing: (1) improved dental indices; (2) improved methods of classifying and maintaining records of the dental health education activities undertaken; (3) better methods of quantifying dental care items and other social and environmental covariables; and (4) more sophisticated forms of multivariate analysis.
During their career, students of dentistry acquire techniques which they will employ later on their patients. Since the health of these patients and society itself cannot be left exclusively to the professional activity of these future dentist, an experimental extra-class experience was carried out with pupils from primary and secondary schools. The students gave the pupils presentations on Nutrition, Calcium and Phosphorus and Caries. The aim of this study was to evaluate: a) the influence of society on the teaching process, and training during the first university year, and b) epidemiologic aspects. Our results indicated that 32.2% of the primary and 15.6 % of the secondary school pupils were unfamiliar with the disciplines presented by the students. According to the evaluations 78.1% of the primary and 94.0% of the secondary school pupils achieved or exceeded the minimum requirements considered necessary for correct nutritional and oral health habits. Evaluations of the students demonstrated that the students who had participated in the activity did not have knowledge superior to that of non-participating students. Therefore this experience can be considered an exercise in utilizing human resources for primary prevention rather than an innovative methodology which improves the teaching-learning process. It also seems recommendable in view of the low cost of the exercise.
