A survey of school dental screening practise in community dental services of England and Wales in 2003

OBJECTIVE: To describe the school dental screening process in Community Dental Services across England and Wales. Basic research DESIGN: Cross-sectional study using a postal questionnaire. CLINICAL SETTING: Community Dental Services. Participants: Clinical Directors of Community Dental Services in England and Wales. MAIN OUTCOME MEASURES: Respondents answers about the objectives of school dental screening, criteria used for referring a child, methods of informing parents of screening results, and methods used to confirm subsequent dental attendance. RESULTS: The response rate for this study was 92.1%. Respondents identified dental registration (75.2%) and attendance at a dentist (82.9%) as objectives of school dental screening. Less than one third (29.5%) saw the activity as having a preventive role. Caries in the primary and secondary dentitions and soft tissue lesions were reported as key criteria for referral. Methods of follow-up of screened positive children differed and were often inadequate; approximately one third of respondents used a letter carried home by the child that did not allow parents to inform the CDS of action taken. Half of the respondents routinely collected data on the number of screened positive children who subsequently visit a dentist. CONCLUSIONS: School dental screening is delivered in a similar fashion throughout England and Wales but methods of informing parents of a positive screen and follow-up mechanisms for children with positive screens vary. Most school dental screening programmes do not collect sufficient data to evaluate the impact of their programmes on children's oral health.     

The effectiveness of school dental screening: dental attendance and treatment of those screened positive

OBJECTIVE: To determine dental attendance and treatment outcomes following two models of dental screening. DESIGN: An observational prospective cohort study. SETTING: Infant, primary and junior schools in the North West of England. SUBJECTS: Children aged six to nine years at the start of the study. INTERVENTIONS: Subjects received a screening examination according to either a 'Traditional model' or 'New model' of school dental screening. MAIN OUTCOME MEASURES: Attendance at a dentist within four months of the intervention and treatment received by children referred via the 'New model' with caries in their permanent teeth. RESULTS: In the 'New model' of school dental screening 46% of screened positive and 41% of screened negative children attended a dentist during the study period. Some 44% of children referred with caries in permanent teeth attended a dentist and 53% of those attending received treatment for the referred condition. Larger proportions of children from disadvantaged backgrounds were screened positive but higher proportions of children from more affluent backgrounds attended the dentist and subsequently received treatment. CONCLUSION: School dental screening has a minimal impact on dental attendance and only a small proportion of screened positive children receive appropriate treatment. The programme fails to reduce inequalities in utilisation of dental services.     

Time absent from school due to dental conditions and dental care in Thai schoolchildren

OBJECTIVES: To assess the number of school hours missed for dental reasons per 1,000 grade 5 primary school children in 1 school year and compare dentally related school absences with those related to medical and social reasons. METHODS: A longitudinal study using a multistage sampling technique was carried out on a sample of 1,211 children attending schools in Lampang province, Thailand. Data on absence were collected from daily school attendance records for 1 year and from children and parents questionnaires and school dental clinic records. Clinical examinations were done using the World Health Organization criteria. RESULTS: A total of 1,158 children (response rate: 95.7 percent) aged 9 to 13 years were examined and returned completed questionnaires. Their caries level was relatively low (DMFT 1.4 +/- 1.7). The children (22.5 percent) reported school absence for any dental reason. The mean number of hours of school absence per year for dental care was 434 hours per 1,000 children (613 hours per 1,000 children when dental screening was included). Among those who actually missed school for dental reasons, the numbers of hours missed were 1,923 hours per 1,000 children. CONCLUSIONS: The level of school absence for dental-related conditions and care was low per child but cumulatively was considerable. The time missed because of dental reasons was substantially less than the time missed because of other health and social reasons.     

Dental caries in schoolchildren in some Danish communities with and without school dental service

ABSTRACT The purpose of the investigation was to compare the caries prevalence (DMF-T) among 762 7th grade children, of whom one-hall had received regular school dental care throughout their school attendance and the other half had never received school dental care. The children were grouped according to social status in order to see if there was any difference in the caries prevalence between the social groups. The caries prevalence in children both with and without school dental service was high, 9.5 DMF-T and 10.5 DMF-T. The prevalence of untreated caries and secondary caries was lowest in the group with school dental service.     

Children's dental health: British expatriate residents in Tokyo, Japan

AIM: To identify in expatriate British parents resident in Tokyo, Japan, their levels of dental health knowledge, patterns of dental health behaviour, and caries status of their children compared to Japanese children. METHODS: 223 parents with children at one school were asked to complete a structured questionnaire. Data were collected on: parental knowledge and behaviours with respect to caries prevention, and sweet consumption of the children. The caries status of the children was established by a clinical examination, using standard criteria. RESULTS: The questionnaire response rate was 66.8%. The mean age of the children was 7.6 years (range 3-11 years). The responses related to 51 British, 21 Japanese, and 20 children who had British and Japanese mixed parents. 33% of British and none of Japanese children had sweet foods frequently. Fluoridated toothpaste was used by 67% of British and 10% of Japanese children. British parents knew about dental caries more than Japanese. 13% of British and 38% of Japanese children were found in the higher caries experience group. CONCLUSION: Parental access to information in the UK and to fluoridated toothpaste in Japan could have helped to prevent dental caries in these expatriate British children.     

The Community Dental Facilitator Project: reducing barriers to dental care

OBJECTIVES: This report describes an initiative developed and implemented by a low-income, urban, Canadian community to respond to their children's dental problems. METHODS: The first strategy pursued by the community was the development of the Community Dental Facilitator Project. This project facilitated children's access to existing government funding for dental treatment, and subsequently facilitated access to treatment at local dental offices. Children in need of treatment were identified by a school dental screening. The facilitation work was done by three lay workers hired from within the community who represented the community's predominant ethnic groups. RESULTS: Parents revealed that barriers to dental care in local dental offices were lack of information about funding programs, language, inflexible work situation, and mistrust of bureaucracy. By the project's end, with the assistance of the facilitators, a significantly increased number of children had been enrolled for government dental benefits (P<.001). In addition to the 123 children identified at the screening as needing treatment, another 30 children "self-referred" to the program. At the end of the project's original funding period, dental appointments had been made for 68 children: 60 (48.8%) of the "screened" group, 8 (26.7%) of the "self-referred" group. One-year telephone follow-up to parents of the screened children revealed that 42 of 59 (71.1%) had completed treatment. CONCLUSIONS: Barriers to dental care for low-income children go beyond economics. A community facilitation model can improve low-income children's access to existing dental services and may reduce the barriers to care for some children requiring treatment.     

The effectiveness of school dental screening: a cluster-randomized control trial

Dental screening of children in schools is undertaken in many countries. There is no evidence that this activity is effective. The objective of our study was to determine if school dental screening of children reduces untreated disease or improves attendance at the population level. A four-arm cluster-randomized controlled trial was undertaken in the northwest of England. In total, 16,864 children aged 6-9 years in 168 schools were randomly allocated to 3 test groups, which received screening according to different models, and a control, which received no intervention. There were no significant differences in caries increment in the primary and secondary dentitions or in the proportions of children attending a dentist after screening between the control group and the 3 intervention arms. School dental screening delivered according to 3 different models was not effective at reducing levels of active caries and increasing attendance in the population under study.     

School screening and parental reminders in increasing dental care for children in need: a retrospective cohort study

Objective: The objective of this study is to assess follow‐up dental care received by children given baseline screening and referrals as part of an ongoing clinical trial. Methods: A retrospective study with two cohorts of kindergarten children who had baseline and follow‐up (9 months later) dental exams was used. The parents/caregivers of children with routine restorative or urgent needs at baseline received a referral letter and telephone reminders to seek care for their child. Children with referrals were evaluated at follow‐up exam for the receipt of care. A baseline caregiver questionnaire provided information on the individual and family characteristics of the children. Results: A total of 303 children had dental exams at both time periods. At baseline, 42 percent (126/303) received referrals and among the referred group19 percent (24/126) received follow‐up care. A greater proportion with urgent referrals (10/30, 33 percent) received care than those with routine referrals (14/96, 15 percent). Baseline dmft decayed, missing, filled primary teeth and DMFT decayed, missing, filled permanent teeth was similar between children who did/did not receive follow‐up care (P = 0.178 and 0.491, respectively). Children receiving referrals had caregivers with less education, higher Medicaid participation, fewer routine care visits, poorer self‐rating of teeth, and a higher proportion of children reporting tooth pain. Children without receipt of follow‐up care had caregivers who were more likely to report not visiting a dentist within the last 5 years and a greater number of missed days from work because of tooth problems. Conclusion: The rate of dental utilization was low even with school screening, referral and parental reminders among poor, largely minority inner‐city kindergarten children.     

Dental attendance and anxiety among public and private school children in Jordan

AIM: To evaluate the levels of dental attendance and anxiety among children of public (lower to middle socioeconomic groups) and private schools (higher socioeconomic groups), and to explore the perceived source of dental fear among them. METHOD: A group of 1,021 children selected by a simple random method from 10 public schools in the five geographic areas of Irbid Governate, Jordan and all 10 private schools were included in this study. All children (mean age 13.1 +/- 0.87 years) completed a questionnaire modified from the Dental Fear Scale (DFS) which also contained items related to dental attendance. RESULTS: Private school children (31.4%) visited the dentist regularly more significantly than public school children (15.0%) (P < 0.001). However, the majority of children (public = 82.6%, private = 67.4%) attended the dentist only in an emergency. The main reason for irregular attendance was 'treatment not needed' (42.2%). About 43-44% of children had dental fear of 'low to moderate type', while the prevalence of 'high dental anxiety' was slightly higher among children of public (11.6%) than those of private schools (6.9%). Fear of specific stimuli (pain and trauma) was the most common source of dental fear reactions among 60-65% of children. The sight and sensation of an anaesthetic needle and sight, sound and sensation of the drill were the most fear eliciting stimuli. Moreover, public school children were found to be more anxious with a significantly higher 'overall dental fear' than private school children (P < 0.05).     

School dental screening does not increase dental attendance rates or reduce disease levels

DESIGN: This was a cluster randomised controlled trial, in which the unit of randomisation was the school. INTERVENTION: Three models of screening were tested against a control. A 'new' model of school dental screening incorporated a consensus view, from clinicians in the northwest of England, on a set of clinical criteria that would prompt a referral following a screening examination. A 'traditional' model involved the delivery of the existing school dental screening programme according to the principle that a child is referred if, in the opinion of the screening dentist, dental care is required. The third intervention tested was a dental information leaflet, distributed via the schools, which encouraged parents to examine their child's mouth and to take their child to a dentist if any problems were noted. Children a ttending the control schools received no intervention during the study period. OUTCOME MEASURE: The main outcome measures were prevalence of teeth with active caries and mean number of teeth with active caries in the permanent or primary dentition. Secondary outcome measures were prevalence of oral sepsis, gross plaque or calculus, and dental trauma to incisor teeth. RESULTS: Seventeen thousand and ninety-eight children in 169 clusters (schools) were eligible for inclusion in the study. One school was withdrawn from the study because of failure to agree to follow the trial protocol. Of the total, 15 004 children were available for baseline examination in 168 schools and 13 570 children received a baseline and outcome examination, representing 80.5% of the eligible population. After adjustment for clustering of children in schools, there was no significant difference in the reduction from baseline in untreated caries between the study groups in either the primary or permanent dentition. Similarly there were no significant differences across the four arms of the study in the secondary outcome measures of prevalence of sepsis, presence of gross plaque or calculus, and trauma to the permanent incisor teeth. In the traditional arms, 42% of children attended a dentist during the study period, with 41% in the new-model arm, 37% in the information-leaflet arm and 38% in the control arm. Although more children in the traditional and new-model arms of the study attended a dental appointment these differences were not statistically significant.CONCLUSIONS: School dental screening delivered according to three different models was not effective at reducing levels of active caries and increasing dental attendance in the population under study.     

Periodontal awareness and knowledge,and pattern of dental attendance among adults in Jordan

AIMS: To provide baseline data on periodontal awareness and health knowledge, and to assess patterns of dental attendance behaviours among 20 to 60 year-old Jordanian adults. METHODS: A questionnaire incorporating items related to personal and socio-demographic data, periodontal awareness and health knowledge, and self-reported dental attendance behaviours. One-thousand questionnaires were distributed among adults attending dental clinics. RESULTS: 743 questionnaires were completed and statistically analysed. About one-quarter of adults reported 'gum bleeding' on brushing, but more subjects (40.4%) believed that they had periodontal disease. Also, 47% of the participants thought that they had a 'rough tooth surface', 16% had 'gum irritation' and 25% had 'bad breath'. There were no statistically significant differences between genders with regard to responses on periodontal awareness (P >0.05). The majority of adults incorrectly defined the meaning of dental plaque and did not know its role in the aetiology of gingival disease. Conversely, the majority of participants (60.8%) were aware that gingival bleeding upon brushing indicated the presence of periodontal disease that can be prevented by brushing and flossing (63.4%), mainly before going to bed (73.9%). The overwhelming majority of subjects (81.4%) were irregular attenders. 'Treatment not necessary' and 'cost' were found to be the common barriers for regular dental attendance. The most common treatment received by the subjects at their last visit was restorative therapy. CONCLUSION: Knowledge and awareness concerning periodontal disease is still poor in Jordan, therefore, more dental health education is needed to improve oral health.     

A randomised control trial of the effectiveness of personalised letters sent subsequent to school dental inspections in increasing registration in unregistered children

Background  

Recent studies have cast doubt on the effectiveness and efficiency of school based dental screening programmes in improving dental attendance or improving dental health. In 2002 the National Dental Inspection Programme was introduced in Scotland which categorises children by their dental health and informs parents of the findings via a personalised letter home and encourages dental registration. In addition, epidemiological data for local and national planning purposes is collected. This replaced an earlier school screening system in Lothian where a generic letter urging registration was sent to children who were identified as not being registered with a dentist. The objective of this study is to compare dental registrations rates among unregistered children in these two school inspection systems with a system where letters were sent home but no dental inspection was carried out.     

A paired comparison of dental care in Canadians with Down syndrome and their siblings without Down syndrome

OBJECTIVE: To test the hypothesis that, controlling for age, Canadians with Down syndrome (DS) have dental care that is different to that of their siblings without DS. METHODS: A cross-sectional survey of parents of children with DS among members of the Canadian Down Syndrome Society (CDSS), using a validated questionnaire. Parents were asked to complete two versions of the questionnaire: one for their child with DS and another for the sibling closest in age without DS. A total of 2327 questionnaires were distributed; 1221 questionnaires for people with DS and 950 for siblings without DS were returned. A paired analysis (McNemar test) of dental care indicators was performed on data from 938 family pairs, stratifying for age. RESULTS: For all the dental care indicators and age groups, many respondents indicated the same behaviours or experiences in their child with DS and a sibling without DS. However, depending on the particular form of dental care and the age group, 0-47% of families reported discordant dental care experiences for their child with DS and a sibling without DS. The greatest differences were observed for yearly consults (P = 0.029), restorations (P < 0.001), fluoride therapy (P = 0.013) and extractions (P = 0.029). CONCLUSION: These observations suggest that compared to their siblings without DS, Canadians with DS are receiving different dental care.     

A comparative radiographic investigation of caries prevalence in Danish schoolchildren

In order to assess the prevalence of untreated caries in two groups of Danish 7th grade (13- to 14-year-old) school children in a blind study, a radiographic investigation was carried out. Only half of the children (394) had received regular school dental care during their years of attendance of primary school; the other children (368) had not. A bitewing radiograph of the right side of the mouth of each child was taken, employing a standardized technique. The radiographs were read without the examiner knowing the group identity of the radiographs. The criteria for discarding poor radiographs, teeth, and tooth surfaces are described. Some of the radiographic results are compared with the clinical caries score of the same group. Most of the radiographs without untreated caries were found among those of the children who received school dental service. Uncertainty of method in connection with radiographic investigation is discussed.     

Dental anxiety and regularity of dental attendance in younger adults

Dental anxiety constitutes a major problem for patients and dental care providers alike. The aim of this study was to examine the relationship between dental anxiety and regularity of dental attendance among young adults. A random sample of 15 course directors (1:50) was asked to participate in the study. Of these, only 10 course-directors agreed to handout the 500 questionnaires. All undergraduate students who participated in this study were asked to complete a questionnaire modified from Dental Fear Survey (DFS) questionnaire and 368 (73.6%) filled forms were returned for statistical analysis. The results showed that only 20.9% were regular dental attendee while the majority (79.1%) were irregular attendee. The reasons given for irregular attendance were 'lack of time' (36%), 'treatment not needed' (34.1%), 'fear from dentist' (13.3%) and 'cost' (16.6%). The sight and sensation of the injection and sight, sound, and sensation of the drill were the most common fear-eliciting stimuli. Increased heart rate was the commonest reported physiological response. Females had higher mean ratings, therefore tended to be more anxious than males. Dental anxiety represented by the mean responses to the items, was found to be higher in irregular dental attendee than regular attendee. In conclusion, this suggests that dental anxiety may affect the seeking of dental care, therefore to be taken into account when training dental care providers.

The ''spread of effect'' of a school based dental health education project

A study was undertaken to evaluate the impact of a school based dental health education programme ("Natural Nashers') upon the families of adolescents receiving the programme. Interviews with 73 randomly selected parents were conducted. One group (n = 35) had a child who had recently received the programme, the other (n = 38) had not. During the interview they were asked if they or other family members (apart from the programme recipient) had changed their dental behaviour or received any new dental information in the previous 2 months. Changes in behaviour were reported from 12 parents in the study group compared with seven in the control. Twenty two parents from the study group reported receiving new dental information in the family compared with four in the control group. The information and reported changes in behaviour related primarily to aspects of disclosing. In 80% of these cases of change or new information in the study group the source was an adolescent who had recently been taught "Natural Nashers'.     

Prevalence of dental anxiety among 5- to 8-year-old Taiwanese children

OBJECTIVES: Many people experience discomfort to a greater or lesser degree about the prospect of dental treatment. Dental treatment can be a terrible experience, especially for children with dental anxiety. This study estimated the prevalence of dental anxiety among 5- to 8-year-old children in Kaohsiung City, Taiwan. METHODS: The Children's Fear Survey Schedule-Dental Subscale (CFSS-DS) was translated into Chinese, and a receiver operating characteristic (ROC) curve was made based on criteria determined from pretest clinical observations of a sample population to set a cutoff score. Then, the parental CFSS-DS was used as a screening tool to survey the dental anxiety levels of 5- to 8-year-old children at kindergartens and elementary schools in Kaohsiung City, Taiwan. Participants were selected by stratified random sampling. The stratification was done by geographic district, age group, and sex. A total of 3,597 valid questionnaires were collected. RESULTS: The Chinese version of the CFSS-DS had an optimal cutoff score of 38/39 (sensitivity was 0.857, specificity was 0.882) with an area under the ROC curve of 0.912. The estimated prevalence of dental anxiety among 5- to 8-year-old children in Kaohsiung City was 20.6 percent. The dental anxiety score was found to decrease as age increased; primary school boys had significantly lower scores. CONCLUSIONS: The prevalence of dental anxiety was found to be high for 5- to 8-year-old Taiwanese children. The study's findings point to the urgent need for preventive health education and intervention programs in Taiwan to promote children's oral health and reduce dental anxiety.     

The relationship between anxiety and dental treatment experience in 5-year-old children

OBJECTIVES: To examine the relationship between dental anxiety, dental attendance and past treatment history in 5-year-old children after taking into account confounding influences. METHODS: A cross sectional study of all 5-year-old children living in Ellesmere Port and Chester. All children were clinically examined and dmft and its components were recorded. A postal questionnaire was sent to parents of participating children to identify whether children attended the dentist on a regular asymptomatic basis or only when experiencing problems. Additionally parents were asked to judge whether they and their child were anxious about dental treatment. The socio-economic status of the family was measured using the Townsend Material Deprivation Index of the electoral ward in which they resided. The bivariate relationships between anxiety and reported attendance experience, past extraction and restoration history were using chi-square and t-tests. Multiple logistic regression analyses identify predictors for dental anxiety. RESULTS: A total of 1,745 children received both a clinical examination and a questionnaire and 1,437 parents responded, a response rate of 82.3%. One in ten parents (10.8b) judged their child to be dentally anxious. Anxious children had significantly (p<0.001] more caries experience (dmft 2.58 vs 1.12). Multiple logistic regression analyses confirmed that anxious children were more likely to be irregular attenders (OR 3.33, 95% Cl 2.22, 5.00), have anxious parents (OR 1.60,95% Cl 1.09, 2.36), and to have undergone dental extraction in the past[OR 3.50, 95% CI 2.10, 5.85), after controlling for gender and socio-economic status. A past history of restoration was not a significant predictor of anxiety after controlling for other factors. CONCLUSIONS: Dental anxiety is a fairly common condition in 5-year-old children in the North West of England. It is closely associated with asymptomatic, irregular attendance pattern, a history of extraction and having a dentally anxious parent. The cause and effect dynamics of these relationships need to be determined.
