A cluster randomized controlled trial of a dental health education program for 10-year-old children

OBJECTIVE: Using a cluster randomized trial, this study tested the effectiveness of a dental health education program designed to improve the oral hygiene and dental knowledge of 10-year-old children. METHODS: Thirty-two primary schools in the northwest of England participated. After a baseline assessment of plaque and the completion of a dental knowledge questionnaire by the children, the schools were allocated randomly to active or control groups. Children in schools allocated to the active group received the dental health program, which consisted of four one-hour lessons. After four months the children were examined clinically and scored for plaque, and a second questionnaire was administered. The schools in the control group were then allocated randomly to receive the program or not over the following three months, the program being withdrawn from the schools who initially received it. A further assessment of plaque was made and a questionnaire administered seven months after the baseline of the study. RESULTS: The active groups had 20 percent and 17 percent lower mean plaque scores than the control group at four and seven months (P < .001). The children's knowledge of which type of toothbrush should be used and the role of disclosing tablets improved in the initial test group when compared with the control group and this was retained over the second part of the study. CONCLUSION: The children receiving the program had significantly lower mean plaque scores and greater knowledge about toothbrushes and disclosing tablets than the control children who had not received the program.     

Improving oral health in institutionalised elderly people by educating caregivers: a randomised controlled trial

OBJECTIVES: This cluster-randomised controlled trial assessed whether oral health care education (OHCE) for nursing home caregivers would achieve improvements in clients' oral health. METHODS: Twenty-two nursing homes were randomly allocated to intervention or control group. Clients were examined at baseline and at follow-up visits 1- and 6-months after caregivers received OHCE. Main outcome measures were denture plaque, denture-induced stomatitis, dental plaque and gingivitis. Differences in group means/medians were compared with adjustment for cluster randomisation. RESULTS: Clients' baseline oral health was poor. After OHCE, the intervention group's oral health scores improved significantly. Reductions in denture plaque scores (0-4 scale) exceeded those of the control group by 1.15 (95%CI=0.83, 1.47) at 1 month and by 1.47 (95%CI=1.13, 1.80) at 6 months. Denture-induced stomatitis prevalence reduced significantly over 6 months compared to the control group (P<0.0001). Group differences in favour of the intervention group were 0.41 (95%CI=0.18, 0.65) at 1 month and 0.34 (95%CI=0.14, 0.53) at 6 months for dental plaque (0-3 scale), and 0.17 (95%CI= -0.01, 0.35) at 1 month and 0.28 (95%CI 0.15, 0.42) at 6 months for gingivitis (0-2 scale). Key differences remained significant after adjustment for clustering effects. The provider's costs would currently be approximately pounds 6700 per year to deliver the intervention to a Health Authority with 100 homes. CONCLUSIONS: Although final levels of residents' oral health were still short of ideal, this study clearly shows that, for a modest cost, OHCE can improve caregivers' knowledge, attitudes and oral health care performance for elderly, functionally dependent clients.     

Oral health care needs among the middle-aged and the elderly in Hong Kong

Abstract A sample of 372 35–44-yr-olds and 537 noninstitutionalized 65–74-yr-olds were clinically examined in an oral health survey of Hong Kong Chinese conducted in 1991. The examination procedures and diagnostic criteria for assessing restorative and extraction treatment need followed those recommended by the World Health Organization. The Community Periodontal Index-based periodontal treatment needs involving index teeth or their replacements were computed from separate clinic scores for maximum probing depth, presence of calculus, and bleeding after probing. A set of criteria for assessing prosthodontic treatment need was specially laid down for this survey. Examiners were calibrated before the survey, and the interexaminer reliability was found to be generally good. Besides reporting the various individual normative treatment need items in the traditional way, the present analysis used some holistic treatment-need categories which may have manpower-requirement implications for the classification of subjects. All dentate subjects surveyed required some treatment. Only 6% of the elderly, all edentulous, required denture work only. Of the 35–44-yr-olds, 42% needed scaling and oral hygiene instruction only, which could be provided by dental hygienists. The treatment needs of the vast majority of the middle-aged and the elderly (mainly scaling; simple fillings; and extractions, dentures, or both) could be easily handled by general dentists. Only about one-fifth of the subjects in both age groups required some complex care such as endodontics, crowns, and advanced periodontal treatment, which could be delivered by senior dentists or dentists with specialist training.     

Developing primary health clinical teams for public oral health services in Tasmania

This paper reviews the problem of socio-economic health inequalities and highlights the relevance of these issues for the delivery of public oral health services in the Australian island State of Tasmania. It contends that unless there is reform of existing public oral health systems, inequities in oral health care linked to socio-economic factors and geographic location will remain. The challenge is, firstly, to understand the current situation and why it has occurred. Secondly, we need to ensure that this understanding is shared across educational and professional sectors for the development of innovative approaches to the problem. Thirdly, we must carry out preliminary research and evaluation for any reforms. Using a combination of approaches, i.e., primary health care, a 'common risk' approach and increasing workforce numbers has been identified as a method showing the most potential to improve access to equitable oral health care. An outline of a current research project evaluating the impact of the integration of primary oral health care clinical teams into public oral health services is provided. The clinical teams combine the skills of the dentist and an expanded role for dual trained dental therapists/dental hygienists. The teams focus on the development of innovative clinical practice in the management and prevention of common oral diseases that take into account the broader determinants of oral health inequality. This project will be conducted in Tasmania, where the dominance of small rural and remote communities, adverse socio-economic factors and shortage of oral health professionals are key issues to consider in planning public oral health services and programmes. The results of the evaluation of the Tasmanian pilot model will contribute to the evidence base that will support the introduction of new approaches to public oral health care.     

A cluster randomized controlled trial testing the effectiveness of a school-based dental health education program for adolescents

OBJECTIVES: This trial investigated the value of a school-based dental health education program in terms of changes in knowledge, reported behavior, and plaque scores. METHODS: A total of 2,678 pupils with a mean age of 12.1 years attending 28 schools participated in a school-based dental health education program. The study used a cluster randomized controlled study design. The health service administrators stipulated that all participants receive the intervention; to meet this requirement, a rolling program of two six-month periods was utilized. During the first six months, half the adolescents received the intervention program, the other half acting as controls. Throughout a further six-month period, all participants received the intervention program. This research design allowed comparisons between participants receiving the program for six and 12 months. At baseline, six, and 12 months, a random subsample of 40 children in each participating school had their plaque scores recorded and a questionnaire was used to record their knowledge of dental health and reported dental behavior. RESULTS: The analysis used the subjects clustered within the schools, which were the units of randomization. The intervention program produced statistically significant improvements (P < .001) in knowledge about periodontal disease and the frequency of sugar intake and dental caries in both assessment time periods. The reported frequency of brushing did not change, but the group who had received 12 months of the intervention were more likely (P < .05) to brush for over a minute. At six months the early intervention group had a statistically significant, 13 percent reduction in the mean proportion of sites with plaque compared with the late intervention group (P = .043). This difference was sustained at 12 months (P = .037). CONCLUSION: This cluster randomized control trial demonstrated that the intervention program resulted in an improvement in knowledge of dental disease and an increase in the reported duration of brushing. These improvements were accompanied by a significant improvement in oral hygiene and a reported reduction in gingival bleeding.     

The effect of different dental treatment strategies on the oral health of children: a longitudinal randomised controlled trial

The aim of the present study is to verify which strategy is the most effective in the treatment of dental decay of the deciduous dentition in a moderate to high caries child population under remote field conditions. This study was carried out in the rain forest of Suriname. Three hundred and eighty schoolchildren, mean age 6.1 years (SD 0.5, range 5.1–7.1 years), were randomly assigned to four different groups: full dental treatment, only extractions, only restorations (ART) and no treatment. Parameters for oral health were defined as caries prevalence (dmft), caries increment, sequela to dental caries and dental pain. Restorative dental care of the primary dentition, by means of ART, resulted in a caries increment from a dmft of 5.48 (SD 3.2) at baseline to 6.35 (SD 2.6) after 2 years (p < 0.001). Extensive dental treatment, performing only extractions, or no treatment did not render significant changes in the caries prevalence of children (p > 0.05). Full dental treatment should be the strategy of choice whenever oral health care programmes are developed. However, when priorities are required due to situational, practical or economical reasons, extraction of severely decayed teeth is an effective treatment strategy.     

Survey of the oral health needs of institutionalised elderly patients in Western Australia

An epidemiological survey of the oral health needs of 1144 elderly patients was conducted in hospitals and nursing homes in Western Australia. Patients were categorised as being either totally dependent (requiring intensive nursing care) or partially dependent (requiring nursing supervision). Of all patients the mean age was 80.2 yr, 70% were women, 74% were edentulous, and 70% needed some form of prosthetic care. Of all dentate patients 56% needed dental scaling (and 17% needed complex periodontal treatment), 47% needed some restorative treatment (with a mean need per patient of 1.1 coronal restorations and 0.4 radicular restoration), and 29% needed one or more dental extractions (with a mean need of 1.4 extractions per patient). Partially dependent patients had statistically significant higher needs for prosthetic work than did totally dependent patients, while the converse applied to extraction needs, but in all other aspects the needs of the two categories of patient did not differ significantly.     

Integration of oral health into primary health care: the role of dental hygienists and the WHO stewardship

Abstract:  Interest in addressing the unmet oral health needs of the citizens of the world has manifested itself, lately, in noteworthy expressions of commitment. Oral health is integrated with general health and support for community programmes offering 'essential oral health' within primary health care (PHC) is increasing. The WHO Global Goals for Oral Health 2020 has assumed a more directed public health orientation, and the Global Oral Health Programme has its focus on modifiable oral risk behaviours. Last, but not the least, opportunities are being created, under the 'stewardship' of the World Health Organization (WHO), for the expansion of oral disease prevention and health promotion knowledge and practices in communities. A review of the literature on community-oriented oral health primary care reveals one dominant and disease-oriented practice model with dental practitioners being the principal and exclusive actors. One alternative to this biomedical model of care that may be better suited to translate health promotion principles into action at community levels is the practice that involves hygienists serving as primary oral health care providers. The WHO 'stewardship' should include the support of dental hygiene practice within PHC, many legislative restrictions and regulatory barriers would be relaxed, thus enabling dental hygienists to respond to the WHO's call for community-based demonstration projects. With their focus on preventive oral care, hygienists are 'best poised' to help accelerate the integration of oral health with primary care, particularly in the light of the compelling evidence confirming the cost-effectiveness of the care delivered by intermediate providers.     

Effect of a health-education program using motivational interviewing on oral health behavior and self-efficacy in pregnant women: a randomized controlled trial

Oral health problems are common among pregnant women. The objective of this study was to examine the effectiveness of motivational interviewing (MI) as a behavior-change technique to enhance self-efficacy and oral health among pregnant women. A randomized controlled trial was conducted with 112 pregnant Iranian women. Women in the intervention group received an education program on oral health using MI during two face-to-face sessions, along with routine health education (two 1-h lectures on oral health changes and needs during pregnancy presented as a lecture by an oral health technician over a 2-wk period). Those in the control group received two 1-h lectures on oral health changes and needs during pregnancy. Oral health behaviors, oral health self-efficacy, and general self-efficacy, were assessed, along with gingival and dental health from baseline to the 3-month follow-up. Analysis of covariance was used to determine differences between intervention and control groups. Scores for both general and specific self-efficacy and for healthy behaviors increased in the intervention group, whereas there was no significant change within controls from baseline to follow-up. Between-group analyses also indicated a significant difference in the scores for self-efficacy and behavior favoring the intervention group. Scores on the gingival inflammation index decreased, as did the number of decayed teeth in the intervention group relative to the control group. The number of filled teeth increased significantly in the intervention group. Health education interventions using MI techniques may help to improve oral health-related self-efficacy and behaviors among pregnant women.     

Effect of automated messaging on oral hygiene in adolescent orthodontic patients: A randomized controlled trial

Objective:To determine whether automated text messages sent daily to adolescent orthodontic patients improves oral hygiene more than weekly reminders.Materials and Methods:A blinded, prospective, randomized controlled trial was designed to evaluate the effects of automated messages on oral hygiene. Subjects were recruited from patients undergoing orthodontic treatment at the Texas A&M University College of Dentistry, Department of Orthodontics. They were being treated with a variety of fixed full appliances in both arches. Subjects were randomly assigned to either a once-a-week text message group or a daily text message group. There were 52 females and 27 males who were 12 to 17 years of age. Oral hygiene was measured at the beginning of the study and again 8.6 ± 0.9 weeks later.Results:The daily reminder group (N = 42) had significantly greater improvements in oral hygiene compliance than the weekly reminder group (N = 37). The daily score decreases were 48%, 21% and 19% for the bleeding index (BI), plaque index (PI), and gingival index (GI), respectively. The weekly score decreases were 27%, 14% and 13% for the BI, PI, and GI. There were no sex differences in hygiene changes during the study. The 42% of patients who completed the survey at the end of the study wanted more frequent messages and reported that messages related to decreasing treatment time were the most effective, while those related to oral hygiene were the least effective.Conclusions:Daily text messages are more effective at improving oral hygiene than weekly text messages.

Evaluation of a dental health education program for midwives

OBJECTIVE: The aim of the present study was to evaluate the effect of a dental health program for the midwives in primary health care services in Izmir, Turkey. METHODS: One hundred sixty-four midwives participated in the pilot project. The program was evaluated by quantitative and qualitative methods. The quantitative method assessed the improvement of the dental knowledge level, whereas the qualitative method was conducted to determine the assessments of the participants. RESULTS: The percentages of correct responses given to knowledge items were higher after the program. The midwives defined their role as an important first step for dental services. Education atmosphere was the best characteristic of the program, whereas lack of a written document was an important limitation. CONCLUSION: Despite some limitations, the program was an effective way of improving the oral health knowledge of the midwives and their motivation for dental services.     

Effectiveness of primary school-based oral health education in West Java,Indonesia

A study in West Java has indicated that involvement of primary health care personnel and schoolteachers in oral health education (OHE) at primary schools is a feasible approach that is sustainable. AIM: The present study aims to assess the effects of that school-based OHE programme on pupils who had completed the programme one and a half years ago. METHODS: Eight experimental and six control primary schools in the same area participated in the study. Out of each school 10 children, aged 8-12-years old, were randomly selected. RESULTS: ANOVA with age and gender as co-variables showed statistically significantly lower (21%) habitual plaque scores among children from experimental schools as compared to those from control schools. Tooth brushing effectiveness had significantly improved among experimental children and they took longer for tooth brushing when supervised. The dmft/dmfs values were comparable but the DMFT/DMFS values of children from experimental schools tended to be lower (not statistically significant) than of those from control schools. Differences in oral health knowledge were apparent but self-reported habits pertaining to oral health were comparable between children from experimental and control schools. CONCLUSION: This school-based OHE programme had a moderate positive effect on oral health knowledge and on habitual plaque levels and on the effectiveness of tooth brushing. The effects on caries levels and on self-reported behaviour were inconclusive.     

Chinese health beliefs and oral health practices among the middle-aged and the elderly in Hong Kong

Abstract The purpose of this paper was to study possible relationships between traditional Chinese health beliefs and health practices in adult Chinese in a modernized society. The study populations comprised 398 35–44-yr-old and 559 65–74-yr-old Hong Kong Chinese. The respondents were categorized into three groups with weak, moderate, or strong Chinese beliefs on the basis of interview questions on the causes of gum disease. Chinese preventive practices and Chinese pain practices were defined according to respondents' reported use of recommended traditional cures. Questions on generally accepted oral practices were phrased in terms of frequency of daily brushing of teeth, use of toothpicks the previous day, and whether or not teeth were flossed the previous day. Around one-third of the respondents had weak, almost one-half had moderate, and around one-quarter expressed strong Chinese health beliefs. No significant differences in Chinese health beliefs were found between men and women in either age group, or between the age groups. In the 35–44 age group, more of those with a higher education were in the “weak” Chinese health belief category, whereas, conversely, more of those with a lower education expressed stronger Chinese health beliefs (P<0.05). Women in both age groups reported significantly more frequent brushing. Toothpicks were used by around three-quarters of both age groups, but flossing was extremely rare. Chinese preventive practices were reported significantly more frequently by those in the older group who held strong Chinese health beliefs than those with moderate or weak beliefs, whereas the trend in the younger group was not significant. Chinese pain practices were reported very infrequently. Chinese health beliefs did not correlate with use variables. In the older group, Chinese health beliefs correlated strongly with preventive practices and with knowledge.     

The oral health of the elderly in Melbourne

A survey of 303 subjects over the age of 60 years collected demographic and oral health status data for analysis. The majority of the sample (64.2 per cent) were edentulous. Over 90 per cent of the dentate subjects required scaling and the removal of plaque (CPITN score of TN2); however, just less than half of the sextants examined were excluded because they contained fewer than two functional teeth. About one-third of the dentate subjects required no treatment for dental caries. Of those who required treatment, most needed only one restoration of any particular type. Total tooth loss was associated with gender, level of education, previous occupation, and birthplace. The need for complex periodontal treatment (TN3) was not high, nor was there a high prevalence of root or cervical dental caries.
