Randomized Clinical Trial of Oral Health Promotion Interventions Among Patients Following Stroke

ObjectiveTo evaluate the effectiveness of oral health promotion interventions on clinical oral health. DesignSingle-blind randomized controlled trial conducted over 3 weeks of in-hospital rehabilitation. SettingStroke rehabilitation ward in Hong Kong. ParticipantsPatients with stroke (N=102) admitted to the rehabilitation ward. InterventionsPatients were randomly assigned either: (1) oral hygiene instruction, (2) oral hygiene instruction and chlorhexidine mouthrinse, or (3) oral hygiene instruction, chlorhexidine mouthrinse, and assisted brushing. Main Outcome MeasuresDental plaque, gingival bleeding, and oral functional status were assessed at baseline and review. Development of infectious complications were also monitored during the clinical trial. ResultsPoor oral hygiene and an overall neglect of oral hygiene practices were observed at baseline. Reductions in dental plaque were significantly greater in the 2 groups receiving chlorhexidine compared with the group receiving oral hygiene instruction alone (P<.001). Reductions in gingival bleeding scores were 3- to 4-fold greater in groups receiving chlorhexidine. No cases of pneumonia were observed during the course of the clinical trial. ConclusionsThe oral health condition of patients may be safeguarded after acute stroke with the use of chlorhexidine mouthrinse in conjunction with a standard mechanical plaque removal tool, such as an electric toothbrush. These interventions are acceptable to the majority of patients, and their administration poses a minimal burden to rehabilitation ward staff.

Understanding oral health promotion needs and opportunities of tobacco quitline callers.

Improving oral health and oral health care are important public health goals. Tobacco users and smokers are at particularly high risk for oral disease and warrant targeted intervention efforts. We assessed the need for and acceptability of targeting tobacco quitline callers for an oral health promotion intervention. We surveyed 816 Washington State Quitline callers to assess their oral health, relevant self-care behaviors, and interest in oral health promotion intervention. Most respondents were female, cigarette smokers, of low socioeconomic status, with no dental insurance. Of the respondents, 79.3% (n=647) had some or all of their natural teeth (e.g., dentate); however, most of these respondents failed to meet recommendations for daily oral hygiene (brushing and flossing) (83.9%, n=543) and had no dental visits in the past year (52.6%, n=340). Similar findings were observed among respondents with no insurance. Many respondents were interested in learning more about how to improve their oral health (57.4%, n=468), willing to speak with a quitline coach about improving their oral health (48.2%, n=393), and open to receiving additional oral health information by mail (62.7%, n=512) or the Internet (50.0%, n=408). People who were receptive to learning how to improve their oral health were significantly more likely to be nonwhite, have a low income, have no dental insurance, and not have visited a dentist in the past year. There is a need and an opportunity to target quitline callers for oral health promotion services, as those most in need of these services were open to receiving them.

The influence of oral health conditions, socioeconomic status and home environment factors on schoolchildren's self-perception of quality of life

BackgroundThe objective this study was to investigate the influence of clinical conditions, socioeconomic status, home environment, subjective perceptions of parents and schoolchildren about general and oral health on schoolchildren's oral health-related quality of life (OHRQoL).MethodsA sample of 515 schoolchildren, aged 12 years was randomly selected by conglomerate analysis from public and private schools in the city of Juiz de Fora, Brazil. The schoolchildren were clinically examined for presence of caries lesions (DMFT and dmft index), dental trauma, enamel defects, periodontal status (presence/absence of bleeding), dental treatment and orthodontic treatment needs (DAI). The SiC index was calculated. The participants were asked to complete the Brazilian version of Child Perceptions Questionnaire (CPQ11-14) and a questionnaire about home environment. Questions were asked about the presence of general diseases and children's self-perception of their general and oral health status. In addition, a questionnaire was sent to their parents inquiring about their socioeconomic status (family income, parents' education level, home ownership) and perceptions about the general and oral health of their school-aged children. The chi-square test was used for comparisons between proportions. Poisson's regression was used for multivariate analysis with adjustment for variances.ResultsUnivariate analysis revealed that school type, monthly family income, mother's education, family structure, number of siblings, use of cigarettes, alcohol and drugs in the family, parents' perception of oral health of schoolchildren, schoolchildren's self perception their general and oral health, orthodontic treatment needs were significantly associated with poor OHRQoL (p < 0.001). After adjusting for potential confounders, variables were included in a Multivariate Poisson regression. It was found that the variables children's self perception of their oral health status, monthly family income, gender, orthodontic treatment need, mother's education, number of siblings, and household overcrowding showed a strong negative effect on oral health-related quality of life.ConclusionsIt was concluded that the clinical, socioeconomic and home environment factors evaluated exerted a negative impact on the oral health-related quality of life of schoolchildren, demonstrating the importance of health managers addressing all these factors when planning oral health promotion interventions for this population.

Oral health promotion interventions on oral reservoirs of staphylococcus aureus: a systematic review

The oral cavity serves as a reservoir of Staphylococcus aureus for infection of the lower respiratory tract and cross-infection to other patients. This systematic review was designed to examine the effectiveness of oral health promotion interventions on this pathogen. The PubMed, ISI Web of Science, and Cochrane Library databases were searched for clinical trials assessing the effect of oral health promotion interventions on oral and oropharyngeal carriage of S. aureus. Oral health promotion interventions on oral reservoirs of S. aureus in both systemically healthy and medically compromised groups consisted of oral hygiene interventions only. There was a lack of evidence pertaining to the effectiveness of mechanical oral hygiene interventions against this pathogen. Chlorhexidine delivered in oral hygiene products such as mouthrinses, gels, and sprays appeared to have some utility against S. aureus, although some studies found equivocal effects. There was a dearth of studies investigating the efficacy of other chemical agents. Although many chemical agents contained in oral hygiene products have proven in vitro activity against S. aureus, their clinical effectiveness and potential role as adjuncts or alternative therapies to conventional treatment remain to be confirmed by further high-quality randomized controlled trials.

Oral health promotion interventions on oral yeast in hospitalised and medically compromised patients: a systematic review

Yeast are major aetiological agents of localised oral mucosal lesions, and are also leading causes of nosocomial bloodstream infections. The purpose of this systematic review was to examine the effectiveness of oral health promotion interventions on the prevalence and incidence of these opportunistic oral pathogens in hospitalised and medically compromised patients. The PubMed, ISI Web of Science and Cochrane Library databases were searched for clinical trials assessing the effect of oral health promotion interventions on oral yeast. Chlorhexidine delivered in a variety of oral hygiene products appeared to have some effect on oral yeast, although some studies found equivocal effects. Although a wide array of other compounds have also been investigated, their clinical effectiveness remains to be substantiated. Likewise, the utility of mechanical oral hygiene interventions and other oral health promotion measures such as topical application of salivary substitute, remains unsettled. Although many chemical agents contained in oral hygiene products have proven in vitro activity against oral yeast, their clinical effectiveness and potential role as adjuncts or alternative therapies to conventional treatment remains to be confirmed by further high-quality randomised controlled trials. This is pertinent, given the recent emergence of yeast resistance to conventional antifungal agents.

Barriers to oral health promotion in the Republic of Ireland

This paper discusses the evaluation of a multi-sector oral health promotion intervention in the Republic of Ireland for children with disabilities. It argues that a lack of awareness about the context of interventions means that sometimes people's health concerns remain unaddressed through a lack of participation. This may actually increase rather than decrease health inequalities. Implementing qualitative methods to provide a context before proceeding with interventions may assist in providing approaches that are fit for purpose when trying to include people in health promotion. A purposive sample of 15 parents or carers of children with disabilities and 18 non-dental professionals were interviewed in either focus groups or on a one-to-one basis. The qualitative analysis indicated that budget constraints were affecting joint working because non-dental professionals were overstretched, feeling that they only had the capacity to carry out day-to-day work with parents and children. The daily demands of caring for a child with disabilities for many parents meant that they were tied to a day-to-day existence. The qualitative evaluation suggested that an initial lack of knowledge about structural, procedural, and budgetary barriers, coupled with insight into the daily demands on parents caring for children with disabilities, meant that all parents were not enabled. Therefore, achieving the aims of the plan could not be a total success for all parents and children from the outset.

Impact of an oral health intervention on pre‐school children &lt;3 years of age in a rural setting in Australia

Australian pre-school children living in rural areas experience higher levels of dental caries than those in metropolitan areas. This may be because of a lack of community water fluoridation. The aim of this study was to evaluate the effectiveness of a community-based intervention to improve the oral health of children in non-fluoridated rural Victoria, Australia. The study was conducted across three local government areas in Victoria, with two receiving the intervention and one remaining with standard care. Although multifaceted, the primary strategy of the intervention was the promotion of early exposure to fluoridated toothpaste, including the distribution, by maternal and child health nurses (MCHNs), of an oral health starter kit including toothpaste, toothbrush and information to parents at their child's 7-8-month health check. Children were followed up annually to the age of three. Infants in the intervention arm experienced less caries (cavitated and pre-cavitated lesions included) than infants in the control arm at the first and second examinations (3.1% with caries in the intervention vs. 6.9% in the control group at exam 1 (adjusted P= 0.07) and 10.8% vs. 19.5% at exam 2 (adjusted P= 0.11), respectively). However potential benefits disappeared at the third examination (29.5% vs. 28.9%, adjusted P= 0.67). This study suggests that an oral health promotion intervention delivered via local MCHNs promoting early exposure to fluoride may be successful in reducing caries in the second year of life but less so in older children when participants have less contact with MCHNs.

A Framework for Implementing Sustainable Oral Health Promotion Interventions.

The present paper addresses basic evaluation and procedural concepts that are involved in the process of implementing sustainable oral health behavioral and social interventions. It is part of a series of thematic articles describing cutting-edge methods for conducting oral health interventions research. Core components for effective intervention implementation are presented as part of a comprehensive model composed of four stages (training, adoption, implementation, and practice), along with sustaining influences involving preparation and maintenance. This model systematically addresses common barriers that can reduce innovation success and permanence. Special attention is given to the measurement and impact of organizational and related contextual influences across stages of the implementation process. Assessment tools and research strategies are recommended and illustrated based on evaluations of interventions implemented in addiction and mental health treatment systems. These tools and research strategies also hold promise for use within the National Institute of Dental and Craniofacial Research Practice-Based Research Networks, as well as other systems of oral health care delivery.

Oral health promotion programmes during orthodontic treatment beneficial

The Cochrane Central Register of Controlled Trials, Medline and Embase databases were searched. A hand search was made of the American Journal of Orthodontics and Dentofacial Orthopaedics, (British) Journal of Orthodontics, European Journal of Orthodontics and Angle Orthodontist, Google Scholar and the reference lists of relevant articles. Only randomised controlled trials (RCT) and quasi-randomised controlled clinical trials (CCT), which specifically stated that they assessed reductions in dental plaque levels and/ or gingival bleeding when comparing oral health promotion (OHP) interventions, were included. Trials that involved plaque removal by a professional (except at baseline) or the use of proprietary antiplaque agents were excluded. Data extraction was carried out independently by two reviewers. Study quality was assessed for their method of allocation, concealment of allocation, masking of assessment and reporting of withdrawals. Direct comparison between the trials was difficult because of the heterogeneity in the outcome measures between the included studies. Six RCT and quasi-randomised CCT met the inclusion criteria. Positive effects on plaque and/ or gingival health were produced in only four of the included trials. OHP did not result in any detectable difference in two of the included trials. None of the trials that were included produced a negative effect of orthodontic OHP on oral hygiene and gingival health. An OHP programme for people undergoing fixed appliance orthodontic treatment produces a short-term reduction (of up to 5 months) in plaque and improvement in gingival health. No particular OHP method produced a greater short-term benefit to periodontal health during fixed appliance orthodontic treatment. Further studies using appropriate methods and, in particular,r longer followup periods are required.

School‐based intervention to promote preadolescents’ gingival health: a community trial

Evaluation of the effectiveness of a school-based oral health promotion intervention on preadolescents' gingival health. A community trial designed for a 3-month intervention study in a representative sample of 9-year-olds (n = 457) in 16 schools in Tehran, Iran. The schools were randomly assigned to three intervention groups and one control group, each group comprising two boys' and two girls' schools. The first group of children (n = 115) received intervention via class work, solving a set of puzzles containing oral health messages, under supervision of their health counsellor. The second group (n = 114), intervention via parents, included an oral health education leaflet and a brushing diary for supervising the child's tooth-brushing; the third group (n = 111) received a combination of both these interventions. The control group (n = 117) had no intervention. Effects of the intervention were assessed as changes in dental plaque and gingival bleeding. Improvements in gingival health were recorded when half of the index teeth with plaque at baseline became clean (acceptable oral hygiene) or when all index teeth with bleeding at baseline became healthy (healthy gingiva). Statistical analysis included chi square, anova, t-test, Number Needed to Treat (NNT) and generalized estimating equations (GEE). At baseline, none of the children were free of plaque and all except for three boys had bleeding. After the trial, acceptable oral hygiene was more frequent in the parental-aid (P < 0.001) and the combined groups (P < 0.05), and healthy gingiva in both groups (P < 0.001) in comparison with the control group. Outcomes in the class-work group did not differ from those in the control group. The GEE models confirmed a strong intervention effect on healthy gingiva in both groups where parents were involved: parental-aid group (OR = 7.7, 95% CI: 2.2-27.7) and combined group (OR = 6.6, 95% CI: 2.0-22.1). In all intervention groups more girls than boys achieved healthy gingiva (OR = 2.5-2.6). Parents' education showed no impact on the outcome. When a school-based oral health intervention involves parents it may result in a significant improvement in the gingival health of preadolescents with poor gingival health at baseline.

Longitudinal association of adolescents’ sense of coherence with tooth‐brushing using an integrated behaviour change model

To determine the association between adolescents' sense of coherence (SOC) and their tooth-brushing behaviour. This 18-month longitudinal study involved a representative sample of 8th-graders (n = 1025) from 11 randomly selected public high schools in the Limpopo Province, South Africa. Data collected by means of a self-administered questionnaire included respondents' socio-demographic profiles, vulnerability to depression, smoking status, dental treatment attendance pattern, frequency of and motivation for tooth-brushing. Based on the responses to the question on readiness to change brushing behaviour and in line with the integrated change model, respondents were also categorized as being in the pre-contemplation, contemplation or preparation/action stages. Respondents' SOC was measured using a six-item adapted Antonovsky SOC scale. Data analysis included chi-squared analysis, t-tests and step-wise multiple logistic regression. At baseline, 72.6% (n = 744) of the respondents reported that they were not consistently brushing twice daily. Of those who did not brush twice daily and were followed up on (n = 578), those living with their mother at baseline not only presented with a greater increase in their SOC over time (follow-up minus baseline), but they were also more likely to be brushing twice daily at the time of the follow-up (15.4% versus 10.6%; P = 0.04). Adding baseline intention state to a multivariate model attenuated the influence of baseline SOC to a statistically insignificant level. However, increasing within-subject SOC changes (beta = 0.16; P < 0.01), living with the mother (beta = 0.11; P < 0.05), smoking (beta = -0.14; P < 0.05), being depression vulnerable (beta = -0.23; P < 0.01) and in the preparation/action stage (beta = 0.13; P < 0.05) remained associated with the transition to twice-daily tooth-brushing. In planning oral health promotion interventions, it should be considered that children's psychological predisposition and family environment might significantly influence their tooth-brushing behaviour.

Efficacy of an oral health promotion intervention in the prevention of early childhood caries

Despite a marked improvement in oral health of Australian children over the last 30 years, severe early childhood caries (S-ECC) affects up to 17% of 2- to 3-year-old children with some requiring hospitalization and invasive treatment. This provided a compelling rationale to develop and test an oral health promotion programme which aimed to reduce this unnecessary suffering. The purpose of this study was to test the efficacy of an oral health promotion programme for the parents of infants, starting during the pregnancy, using a randomized controlled trial. A programme was developed around the provision of anticipatory guidance to nulliparous women (women expecting their first child) in Adelaide. Mothers in the test group received oral health promotion information during pregnancy, and later when the child reached 6 and 12 months of age. After the second round of information the test group mothers were randomized again. The information was reinforced in one of the test subgroups through a telephone consultation. There was no contact with mothers in the control group after enrolment. At the age of 20 +/- 2.5 months all test and control group children were examined by a dentist. The case definition of an incidence of S-ECC was one or more upper incisor teeth being carious at the level of a cavitated or noncavitated lesion. The differences in S-ECC incidence between the test and control groups, and the test subgroups were analysed. Of 649 women enroled in the programme (test group 327, control group 322), 441 had their child examined at follow-up. The incidence of S-ECC in the test group was 1.7% and in the control group 9.6% (P < 0.001). An oral health promotion programme based on repeated rounds of anticipatory guidance initiated during the mother's pregnancy was successful in reducing the incidence of S-ECC in these very young children.

Role of African‐American Fathers in Child‐Rearing and Oral Health Practices in an Inner City Environment ‐ A Brief Communication

This study assesses parenting behaviors, health behaviors and attitudes in a sample of disadvantaged African-American fathers and evaluates the potential of fathers as recipients of oral health promotion interventions. Participants were 60 African-American fathers whose children were enrolled in a childhood caries prevention study at Women and Infant Child Program (WIC) (n=25) or who were members of a Young Fathers' Program (n=35) at an urban health center. Demographic factors, oral health knowledge, dental self-efficacy, parenting behaviors, readiness to change, and health promotion behaviors were assessed. Participants averaged 30.8 years of age (sd=8.6); children averaged 2.1 years (sd=0. 9). Half of the fathers always have lived with their own children and 92% had regular physical contact with their children. Almost half of the sample reported 'fair/poor' oral health status, while less than 25% reported 'fair/poor' general health. Fathers had high oral health knowledge scores (x=7.7 correct of 9 items), and high readiness for change scores at the action stage (X=12.2 of 15; sd=1.9). dental self-efficacy scores were moderate (X=15.7 of 24; sd=5.5). Half of the fathers shared or had sole responsibility for brushing their children's teeth; 90% report children's teeth were brushed daily. African- American fathers participated in childrearing and oral health promotion behaviors.

Sociobehavioural risk factors in dental caries – international perspectives

Diseases probably have their roots in a complex chain of environmental and behavioural events which are shaped by broader socioeconomic determinants. Most studies of sociobehavioural risk factors in dental caries have been carried out in industrialized countries, but such reports from low- and middle-income countries have been published in recent years. World Health Organization international collaborative studies and other international studies of social factors in dental caries using the same methodology provide empirical evidence of social inequality in oral health across countries and across oral health care systems. The paper highlights the challenges to dental public health practice, particularly the importance of risk assessment in estimating the potential for prevention. In future public health programmes, systematic risk factor assessment may therefore be instrumental in the planning and surveillance of oral health promotion and oral disease intervention programmes.

Oral health promotion programme for older migrant adults

This study evaluated the impact of a community-based oral health promotion programme on the use of oral health services, oral health knowledge, attitudes, and practices of older Greek and Italian adults attending community clubs and living in Melbourne, Australia. The oral health promotion intervention consisted of three components: a series of oral health seminars, held at the clubs in the participants' native languages, the provision of oral health care products, and the production of oral health information sheets. The intervention programme was known as the Oral Health Information Seminars/Sheets (ORHIS). The content of each session was determined following suggestions and findings from the data collected. A pre-test-post-test non-equivalent control group quasi-experimental design was chosen to evaluate the intervention. A total of 520 independent-living older adults, members of Greek or Italian social clubs participated in this evaluation. Participants who took part in the intervention responded with higher levels of achievement than those in the control groups. After controlling for baseline variables, experimental groups were significantly more likely than the control groups at post-test to have improved oral health attitudes, oral health knowledge, and self-assessed physical health status, as well as, self-reported oral hygiene practices and use of oral health services. The ORHIS approach was successful within the setting of social clubs, and highly acceptable to these communities. As such, it represents a helpful approach for the design of (oral) health interventions in older adults. Further research is required to test the long-tem impact including the economic evaluation of the ORHIS approach.
