Dental RECUR Randomized Trial to Prevent Caries Recurrence in Children

The purpose of this study was to determine the efficacy of a dental nurse-delivered intervention-the Dental RECUR Brief Negotiated Interview for Oral Health (DR-BNI)-in reducing the recurrence of dental caries in children who have a primary tooth extracted. It was based on a 2-arm multicenter randomized controlled trial with blinded outcome assessment. Participants were 5- to 7-y-old children (n = 241) scheduled to have primary teeth extracted in 12 UK centers. Test intervention parents (n = 119) received DR-BNI led by trained dental nurses. DR-BNI is a 30-min structured conversation informed by motivational interviewing with a forward focus to prevent future caries. Preventive goals are agreed, and a review appointment is made with child's general dental practitioner, who is advised to treat the child as being at high caries risk. The control intervention (n = 122) was a parent-nurse conversation about child's future tooth eruption, with advice given to visit a general dental practitioner as usual. At baseline, the DR-BNI group's mean dmft was 6.8, and the control group's was 6.3. A median of 5 teeth were extracted, mainly under general anesthesia. Final dental assessments were conducted by a single examiner visiting 189 schools 2 y after intervention; 193 (80%) of 241 children were examined. In the control group, 62% developed new caries in teeth that were caries-free or unerupted at baseline, as compared with 44% in the test group, a significant reduction (P = 0.021). The odds of new caries experience occurring were reduced by 51% in the DR-BNI group as compared with control. There was a 29% decrease in the relative risk of new caries experience in the DR-BNI group as compared with control. This single low-cost, low-intensity intervention was successful in significantly reducing the risk of recurrence of dental caries in children. This trial has implications for changing pediatric dental practice internationally. Training in and implementation of a motivational interviewing-informed brief intervention provides opportunities for dental nurses to facilitate behavior change improving the oral health of children at high caries risk (ISRCTN 24958829).

Systematic review of post-treatment psychosocial and behaviour change interventions for men with cancer

OBJECTIVES

The psychosocial impacts of a cancer diagnosis include reduced quality of life, poorer inter-personal relationships, hopelessness and mental illness. Worse outcomes, including mortality rates have been found for single men with cancer compared with women and partnered men. The aim of this systematic review was to examine the effectiveness of post-treatment psychosocial and behaviour change interventions for adult men with cancer, in order to inform the development of an intervention. A focus on single men was intended.

METHODS

Ten databases were searched via Ovid and Web of Science. Papers were systematically extracted by title, abstract and full paper according to the inclusion/exclusion criteria. Full papers were assessed by two authors.

INCLUSION CRITERIA

participants at any stage of a cancer diagnosis, > or =50% male and aged 18+; psychosocial and/or behavioural post-treatment interventions, using any format; a one-three level of evidence. Couple/carer/family interventions were excluded.

RESULTS

From 9948 studies initially identified, 11 were finally included in the review. They implemented cognitive behaviour therapy, hypnosis or psychoeducational interventions. All studies had some positive results, however, lack of reporting of intervention content and methodological issues limit the findings. No studies intervened with single men, and none provided comparative outcomes for marital status.

CONCLUSIONS

Effectiveness of interventions was difficult to assess as, while all had benefits, their generalisability was limited due to methodological and reporting limitations. Improved reporting procedures are required to allow for replication.

Developing explanatory models of health inequalities in childhood dental caries

OBJECTIVE

Long-term aim is to determine optimum interventions to reduce dental caries in children in disadvantaged communities and minimise the effects of exclusion from health care systems, of ethnic diversity, and health inequalities.

DESIGN

Generation of initial explanatory models, study protocol and development of two standardised measures. First, to investigate how parental attitudes may impact on their children's oral health-related behaviours and second, to assess how dentists' attitudes may impact on the provision of dental care.

SUBJECTS

Core research team, lead methodologists, 44 consortium members from 18 countries. To complete the development of the questionnaire, the initial set of items was administered to parents (n = 23) with children in nursery schools in Dundee, Scotland and sent to the same parents one week later. A standardised measure examining barriers to providing dental care for children aged 3 to 6 years was developed. 20 dentists working in primary dental care in Scotland completed the measure on two different occasions separated by one week.

RESULTS

Explanatory models were developed. Family questionnaire: test-retest reliability excellent (r = 0.93 p < or = 0.001) with very good internal reliability (alpha = 0.89). Dentists questionnaire: excellent test-re-test reliability r = 0.88, (alpha = 0.90).

CONCLUSIONS

Interaction between consortium members enhanced the validity of the questionnaires and protocols for different cultural locations. There were challenges in developing and delivering this multi-centre study. Experience gained will support the development of substantive trials and longitudinal studies to address the considerable international health disparity of childhood dental caries.

International comparisons of health inequalities in childhood dental caries

OBJECTIVE

To undertake formative studies investigating how the experience of dental caries in young children living in diverse settings relates to familial and cultural perceptions and beliefs, oral health-related behaviour and oral microflora.

PARTICIPANTS

The scientific consortium came from 27 sites in 17 countries, each site followed a common protocol. Each aimed to recruit 100 families with children aged 3 or 4 years, half from deprived backgrounds, and within deprived and non-deprived groups, half to be "caries-free" and half to have at least 3 decayed teeth.

OUTCOME MEASURES

Parents completed a questionnaire, developed using psychological models, on their beliefs, attitudes and behaviours related to their child's oral health. 10% of children had plaque sampled.

RESULTS

2,822 children and families were recruited. In multivariate analyses, reported toothbrushing behaviours that doubled the odds of being caries-free were a combination of brushing before age 1, brushing twice a day and adult involvement in brushing. Analyses combining beliefs, attitudes and behaviours found that parents' perceived ability to implement regular toothbrushing into their child's daily routine was the most important predictor of whether children had caries and this factor persisted in children from disadvantaged communities. 90% of children with lactobacillus had caries.

CONCLUSIONS

Parental beliefs and attitudes play a key role in moderating oral health related behaviour in young children and in determining whether they develop caries. Further research is indicated to determine whether supporting the development of parenting skills would reduce dental caries in children from disadvantaged communities independent of ethnic origin.

Risk factors for dental caries in young children: a systematic review of the literature

OBJECTIVE

To conduct a systematic review of the literature on risk factors for dental caries in deciduous teeth of children aged six years and under, to give a scientific framework for the international collaborative studies on inequalities in childhood caries.

METHOD

Accepted guidelines were followed. Studies were identified by electronic searching and reviewed on the basis of key words, title and abstract by two reviewers to assess whether inclusion criteria were met. Copies of all articles were obtained and assessed for quality according to the study design.

RESULTS

1029 papers were identified from the electronic search, 260 met the prima facie inclusion criteria. 183 were excluded once full copies of these papers were obtained. Of the 77 studies included, 43 were cross sectional, 19 cohort studies, 8 case control studies and 7 interventional studies. Few obtained the highest quality scores. 106 risk factors were significantly related to the prevalence or incidence of caries.

CONCLUSION

There is a shortage of high quality studies using the optimum study design, i.e. a longitudinal study. The evidence suggests that children are most likely to develop caries if Streptococcus Muttans is acquired at an early age, although this may be partly compensated by other factors such as good oral hygiene and a non-cariogenic diet. Diet and oral hygiene may interact so that if there is a balance of 'good' habits by way of maintaining good plaque control and 'bad' habits by way of having a cariogenic diet, the development of caries may be controlled.

Barriers to the treatment of childhood caries perceived by dentists working in different countries

OBJECTIVE

To explore whether dentists' beliefs and attitudes to providing preventive and restorative dental care for young children can form a barrier to the provision of care.

BASIC RESEARCH DESIGN

The Barriers to Childhood Caries Treatment (BaCCT) Questionnaire, a standardised international measure was developed and applied.

PARTICIPANTS

Through a research consortium, each site was asked to recruit 100 dentists. The sample participating was not intended to be nationally representative. Dentists were mainly randomly selected and contacted by mail with one or more mailings depending on site.

RESULTS

2,333 dentists in 14 countries and 17 sites participated. Factor analysis identified four factors as potential barriers. Two factors were found to be barriers in many sites. First, in most countries, dentists agreed that young children's coping skills limit their ability to accept dental care. Secondly, dentists with negative personal feelings, for example, that providing care can be stressful and troublesome and that they feel time constrained. Differences in dentists' beliefs can be partly explained by their work profile, with those treating children often, and those working under systems where they feel they can provide quality care being least likely to identify barriers to providing care for children.

CONCLUSIONS

The BaCCT Questionnaire was determined to be a valid psychometric measure. Separately, it was found that health systems do impact on dentists' ability to deliver preventive and restorative care for children but that these effects vary across countries and further work is needed to determine how best these should be examined.

Familial and cultural perceptions and beliefs of oral hygiene and dietary practices among ethnically and socio-economicall diverse groups

OBJECTIVE; The aim of this international study was to develop a valid and reliable psychometric measure to examine the extent to which parents' attitudes about engaging in twice-daily tooth brushing and controlling sugar snacking predict these respective behaviours in their children. A supplementary objective was to assess whether ethnic group, culture, level of deprivation or children's caries experience impact upon the relationships between oral health related behaviours, attitudes to these respective behaviours and to dental caries.

CLINICAL SETTING

Nurseries, health centres and dental clinics in 17 countries.

PARTICIPANTS

2822 children aged 3 to 4 years and their parents.

MAIN OUTCOME MEASURES

Dental examination of children and questionnaire to parents.

RESULTS

Factor analysis identified 8 coherent attitudes towards toothbrushing, sugar snacking and childhood caries. Attitudes were significantly different in families from deprived and non-deprived backgrounds and in families of children with and without caries. Parents perception of their ability to control their children's toothbrushing and sugar snacking habits were the most significant predictor of whether or not favourable habits were reported. Some differences were found by site and ethnic group.

CONCLUSIONS

This study supports the hypothesis that parental attitudes significantly impact on the establishment of habits favourable to oral health. An appreciation of the impact of cultural and ethnic diversity is important in understanding how parental attitudes to oral health vary. Further research should examine in a prospective intervention whether enhancing parenting skills is an effective route to preventing childhood caries.
