Dental screening in schools: the views of parents, teachers and school nurses.

OBJECTIVES: To obtain insight into the views of relevant 'stakeholders' (parents, teachers and school nurses) in dental screening in schools. METHODS: Eight schools in Chester and Ellesmere Port in the UK formed the setting of this study. A teacher from each school participated in one-to-one interviews, and focus groups for parents were carried out in each school. A focus group for school nurses working in the locality was also held. The same trained researcher undertook the interviews and focus groups; all interviews and focus groups were tape recorded, transcribed verbatim and thematically analysed independently by two trained individuals. RESULTS: Teachers, school nurses and parents all perceived the process of negative consent and the current dental examination as acceptable. The follow up procedure for identification of screened positive children was seen as inadequate. There was a strong feeling within each group that parents were ultimately responsible for their children's oral health and that state institutions had a limited role in ensuring children attended and received dental treatment. CONCLUSIONS: All of the groups considered it was primarily the responsibility of parents to take screened positive children to see a dentist. The NHS has limited influence on this process. This fact represents a significant challenge to improving the effectiveness of school dental screening.

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.

The development of a consensus among primary care dentists of referral criteria for school dental screening.

OBJECTIVE: To obtain consensus amongst a sample of primary care dentists in the North West of England on a set of clinical criteria that should trigger referral following school dental screening. DESIGN: Delphi process. SETTING: Primary dental care, England 2002. METHOD: Primary care dentists in the North West of England were randomly selected to complete a two round 'Delphi exercise' that included 10 potential referral criteria. The dentists were invited to express their level of support for the inclusion of each referral criterion. MAIN OUTCOME MEASURES: Level of agreement for each referral criterion. Acceptance of any criterion was that the interquartile range should be no more than 3 scale points with the lower value being no less than 7. RESULTS: Eighty-eight dentists, (72.7%), completed the Delphi exercise. Six referral criteria met with the groups' approval: Child with caries in permanent dentition. Child with darkened/discoloured permanent incisors. Child aged 9-10 years with overjet greater than 10 mm. Child over six years with either gross plaque, calculus or swollen gums. Child with evidence of sepsis. Child registered with a GDP with caries in permanent dentition. CONCLUSION: It is possible for a representative sample of primary care dentists in the North West to agree referral criteria following school dental screening.

A randomised controlled trial of the effect of outreach placement on treatment planning by dental students.

UNLABELLED: Undergraduate dental students' curricula are being supplemented with primary care placements. OBJECTIVE: To compare the effect of outreach placement and traditional hospital-based training alone on students' treatment planning ability. DESIGN: Randomised controlled trial.Setting Four existing primary care placements in England during 2004. SUBJECTS AND METHODS: At follow-up the fourth-year students took a history from a standard 'patient' then recorded a treatment plan. Interview skill was scored. The history and plan were assessed by clinicians blind to the intervention. INTERVENTION: Five-week block outreach placements for 25 of 49 students. MAIN OUTCOME MEASURES: Interviewing skill, quality of dental and social histories, the appropriateness of planned treatments and the consideration of wider issues. RESULTS: The two groups were similar in the scores for interviewing and taking a dental history. The outreach group scored higher for capturing a social history (outreach mean 4.4, SD = 2.1, n = 22 and hospital 2.8, SD = 1.9, n = 23; p = 0.01) and for developing an appropriate treatment plan (5.6 [SD = 2.1] and 3.9 [SD = 2.3]; p = 0.01). There were no differences in scores relating to the wider issues. CONCLUSION: Dental outreach training was significantly more effective than traditional training alone in improving students' ability to capture relevant points of social history from a patient and to consider them when planning treatment.

Salaried services in the delivery of dental care in Western industrialised countries: implications for the National Health Service in England.

OBJECTIVE: To examine the provision of dental services by salaried personnel in the countries of Western Europe, together with Australia, Canada and New Zealand, and to weigh the merits of this method against alternatives, namely, capitation and fee for item of service. In light of the findings, to consider the future role of salaried dental services in the National Health Service (NHS) in England. METHOD: Information was gathered from published reports, the World Wide Web and by mailed questionnaire to national chief dental officers or equivalents. RESULTS: Narrative descriptions of service provision in the countries with salaried primary dental care services were compiled. Demographic, macro-economic, workforce, and oral health data for the broader spectrum of Western industrialised countries were tabulated. Examination of the quantitative data showed no strong associations between variables. CONCLUSIONS: Dental services delivered by a salaried workforce can be costly in relation to the volume of clinical activity produced. However, deployment of clinical auxiliary personnel can keep costs down. Salaried services foster a preventive approach to care and are particularly suitable where care is directed towards vulnerable groups within the community. Salaried staff generally receive a lower level of remuneration than private practitioners but usually work in an environment less subject to undue pressures of time.

The use of general anaesthesia for the extraction of children's teeth. Results from two UK dental hospitals.

AIM: To study the reasons forgiving children a general anaesthetic (GA) for the extraction of teeth, in two different paediatric dentistry centres and to compare them with draft guidelines disseminated for discussion by the British Society of Paediatric Dentistry (BSPD). METHODS: Data were collected on children who required GA extractions over a two month period (1st may to 30th June 2004) at the Paediatric Dental Units of Liverpool University Dental Hospital (LUDH) and the University Dental Hospital of Manchester (UDHM). The information collected included date of birth, gender, date of referral, date of assessment and date of GA. The reason for the GA was noted in terms of the proposed BSPD guidelines for short GA. RESULTS: A total of 264 and 268 children required extractions under GA at LUDH and UDHM respectively. At LUDH the main reason in 189 (72%) children was severe pulpitis requiring immediate relief of pain where a child does not have the intellectual maturity to cope with treatment under local analgesia (LA). This was followed by failed extractions under LA in 53 (20%) children. This reason is not listed under the proposed BSPD guidelines. At UDHM the main reason for GA in 114 (42%) children was symptomatic teeth causing pain in more than two quadrants (or in two quadrants necessitating the use of bilateral inferior dental blocks). CONCLUSIONS: There were differences in the clinical rationale for GA between children attending the two centres. Further information is needed to refine the proposed guidelines on the use of GA for dental extractions in paediatric dentistry. The guidelines need to be flexible and updated to reflect changes in practice and service provision.

General dental practitioners' views on the use of stainless steel crowns to restore primary molars.

AIM: To ascertain general dental practitioners' views on the use of stainless steel (pre-formed metal) crowns to restore carious primary molars. METHOD: Ninety-three general dental practitioners were selected at random from those practising in Lancashire, Cheshire and Greater Manchester in 2003 and interviewed separately about the clinical care they provide to the primary dentition. Before the interview participants recorded the care they would provide for a case scenario, describing a child with a carious lesion that the British Society of Paediatric Dentistry (BSPD) guidelines indicate should be treated with a stainless steel crown. RESULTS: In answering the case scenario only six (7%) of the dentists reported that they would fit a stainless steel crown. Of the 93 dentists interviewed 71% knew of the BSPD guidelines, but only 18% had ever fitted a stainless steel crown in general practice. Reasons given for not using stainless steel crowns were they are inappropriate for many children, time consuming to fit, difficult to manipulate, expensive, and ugly. CONCLUSION: The BSPD guidelines on the use of stainless steel crowns do not reflect the views of the majority of general dental practitioners who consider these crowns unsuitable for most children and an impractical restorative technique in busy daily practice.

Developing dental education in primary care: the student perspective.

A pilot outreach course in restorative dentistry based in community clinics began in 2001. As part of the evaluation, 48 fourth year students completed a questionnaire about their opinions of the new course, and about restorative dentistry clinics in the dental hospital. Time management was the most frequently mentioned gain from outreach. In relation to the dental school, students most often saw the specialised teaching staff as a gain. Outreach was equally or more important for students' confidence in clinical diagnosis of dental caries, treatment planning, direct restorations, communicating with patients, and managing patients, time, and resources. The dental hospital was equally or more important for their confidence in the diagnosis of periodontal disease, root planing, crowns, bridges, dentures, and communicating effectively with laboratory staff. Patients in outreach were seen as different from those at the dental hospital because they were unselected, and had different treatment needs. Meeting course requirements was the most frequent concern about outreach. In relation to the dental hospital, students were most often concerned about the quality of teaching and support available. Outreach and the dental hospital provided complementary experiences and the new course met its educational objectives.

Patients treated by dental students in outreach: the first year of a pilot project.

This paper describes the patients treated by 4th year undergraduate students during the first year of a pilot outreach course to teach Restorative Dentistry in community clinics in 2001-02. Data were collected from 908 summaries of patient treatment completed by the students, and from 139 patient questionnaires. Some 75% of patients were aged between 16 and 64, 58% were female, and 16% had dental phobia or anxiety. Most lived locally to the clinic and 41% made their initial contact as an emergency or drop-in. Some 37% made only a single visit (including children treated as emergencies) but 22% made six or more visits. Did not attend (DNA) was a problem and 18% of patients DNA to complete their treatment. Students undertook the full range of restorative procedures, with the emphasis on direct restorations, preventive treatment and advice, scaling, extractions and emergency treatment. Patients' main reasons for attending the clinic were lay recommendation, the need for treatment, convenience, free treatment, or the lack of access to a dentist. Some 30% said they did not have or did not know of an alternative source of dental care, and half had not seen a dentist for at least 2 years. The study demonstrates that despite difficulties related to attendance, a suitable patient base can be established offering students the opportunity to provide comprehensive care for adults in a primary care setting.

The relationship between interleukin-10 gene polymorphism at position -1082 and susceptibility to gingivitis in children.

BACKGROUND: Interleukin (IL)-10 is an anti-inflammatory cytokine. The protective role of this cytokine against different diseases has been demonstrated in several studies. However, no such study has been carried out on gingivitis. The objective of this study was to determine whether differences exist between Caucasian children with and without gingivitis in the distribution of IL-10 alleles at position -1082. METHODS: A total of 260 Caucasian children (86 controls, 174 patients), aged 8 to 12 years, from the University Dental Hospital of Manchester, U.K., were examined. Plaque (PI), calculus (CI), gingival (GI), and bleeding on probing (BOP) indices were used to assess gingival health. DNA was obtained from buccal epithelial cells. Amplification refractory mutation system polymerase chain reaction (ARMS-PCR) was used for genotyping IL-10 polymorphism. Chi square tests were carried out to test the association between allele and genotype frequencies and the severity of gingivitis. Multiple logistic regression was used to determine the role of IL-10 gene polymorphism at position -1082 while adjusting for potential confounders such as plaque, age, and gender. RESULTS: Gingivitis was present in 67% of the children examined. Frequencies of alleles -1082*A and -1082*G were 45% and 55%, respectively. An increased risk of having gingivitis was found in allele A positive children (G/A, A/A); 75% versus 25% in allele A negative children (G/G); (P = 0.01). The -1082*A allele was significantly more common in children with gingivitis; 49% versus 37% in controls (P = 0.01). Multivariate logistic regression analysis showed that allele A remained a risk factor for gingivitis in children (P = 0.03) regardless of plaque or age. Also, allele A positive children were at increased odds of having gingivitis of 1.8 (95% confidence interval [CI]: 1.05 to 3.06) compared to allele A negative children after adjusting for plaque, age, and gender. CONCLUSION: These data suggest that the -1082*A allele could be a risk factor for gingivitis.

Dental caries experience of British children in an international context.

OBJECTIVES: To document data on current and past levels of dental decay in British children and compare trends with those in other countries, in Europe in particular. METHOD: Data were abstracted from multiple sources and collated and tabulated. RESULTS: The dental health of the majority of British children has improved dramatically since the early 1970s. Twelve-year-old children now have on average less than one decayed, missing (extracted) or filled tooth. Levels of dental decay in UK children at 5 and 12 years are among the lowest in the world. There are still marked inequalities in the dental decay experience of children between the territorial regions of the UK, high and low socio-economic groups, and regular and symptomatic dental attenders. Many children in areas of deprivation are either not motivated to seek dental treatment or experience barriers in obtaining it. In parallel with improvements in the dental health of the majority of children, the proportion of UK adults who have no natural teeth has fallen from 37% to 12% over the past four decades. Total tooth loss is now confined almost entirely to individuals over 45 years of age. Most of the improvements in children's dental health are attributable to environmental factors, in particular the widespread availability of fluoride containing toothpastes since the 1970s. There are clear benefits from fluoridation of public water supplies over and above those attributable to other factors. CONCLUSIONS: The findings suggest initiatives should be directed to bringing children from deprived backgrounds under the umbrella of dental care. To help alleviate the inequalities in dental health, water fluoridation should be implemented, in urban industrial areas in particular, where levels of dental decay are still unacceptably high.

A staged intervention dental health promotion programme to reduce early childhood caries.

OBJECTIVE: This paper reports the results of a community trial to assess the effects of a multi-stage dental health promotion programme in reducing Early Childhood Caries (ECC). RESEARCH DESIGN: Two health districts (Primary Care Groups) were matched for dental disease levels and socio-demographic factors. One was randomly allocated to be the test Primary Care Group (PCG), the other the control PCG. Children in the test PCG received a series of interventions to support positive dental health behaviour from the age of 8 to 32 months. Interviews were conducted with parents of children aged 21 months and clinical examinations were undertaken on a larger cohort of children aged 3-4 years in test and control PCGs. SETTING: The interventions were gift bags containing a trainer cup, toothpaste containing 1,450 ppm F and toothbrush, and advice given to the children's parents on attendance at designated clinics and medical practices and further paste and brushes posted to the children's homes. Parents were interviewed on the telephone. Examinations took place at Children's Centres and nursery departments attached to primary schools. OUTCOME MEASURES: Severity and prevalence of ECC and general caries and proportion of parents reporting adopting dentally healthy behaviours. RESULTS: In the test PCG the prevalence of ECC in children who had received the interventions was 16.6% compared with 23.5% of children in the control area, a reduction of 29% (p=0.003). The mean dmft (1.17) and prevalence of general caries experience (28.7%) in the test children were also significantly lower than for children in the control PCG (1.72: 39.2%) (p=0.001). Analysis from a community perspective, which included data from all children examined in both areas, showed the prevalence of ECC in the test and control PCGs was 21.3% and 22.8% respectively and the mean dmft 1.47 and 1.72. The proportion with general caries experience remained statistically significant in favour of the test area 33.8% vs 39.9% (p=0.01). Parents in the test PCG were more likely to report cessation of bottle use (33% vs 18%), use of sugar-free drinks (49% vs 24%), commencement of brushing before first birthday (45% vs 27%) and twice daily brushing (52% vs 34%). CONCLUSION: The parents who received this multi-stage intervention were more likely to report adoption of three positive oral health behaviours; using a trainer cup from one year of age, using safe drinks and brushing twice daily with a fluoride toothpaste. The programme failed to reduce the prevalence of ECC in the community but the prevalence of ECC and general caries experience among the children who participated was less than among children in the control PCG.

Thermal effects of the Er:YAG laser on a simulated dental pulp: a quantitative evaluation of the effects of a water spray.

OBJECTIVES: To quantify the temperature increments in a simulated dental pulp following irradiation with an Er:YAG laser, and to compare those increments when the laser is applied with and without water spray. METHODS: Two cavities were prepared on either the buccal or lingual aspect of sound extracted teeth using the laser. One cavity was prepared with water spray, the other without and the order of preparation randomised. Identical preparation parameters were used for both cavities. Temperature increments were measured in the pulp chamber using a calibrated thermocouple and a novel pulp simulant. RESULTS: Maximum increments were 4.0 degrees C (water) and 24.7 degrees C (no water). Water was shown to be highly significant in reducing the overall temperature increments in all cases (p<0.001; paired t-test). None of the samples prepared up to a maximum of 135 J cumulative energy prepared with water spray exceeded that threshold at which pulpal damage can be considered to occur. Only 25% of those prepared without water spray remained below this threshold. DISCUSSION: Extrapolation of the figures suggests probably tolerable limits of continuous laser irradiation with water in excess to 160 J. With the incorporation of small breaks in the continuity of laser irradiation that occur in the in vivo situation, the cumulative energy dose tolerated by the pulp should far exceed these figures. CONCLUSIONS: The Er:YAG laser must be used in conjunction with water during cavity preparation. As such it should be considered as an effective tool for clinical use based on predicted pulpal responses to thermal stimuli.

Relationship between area deprivation and the anticaries benefit of an oral health programme providing free fluoride toothpaste to young children.

OBJECTIVE: To determine the effectiveness of providing free toothpaste containing either 1450 or 440 ppm F on caries experience in 5-year-old children living in areas with different levels of material deprivation. DESIGN: Five-year, examiner-blind, randomized, controlled, parallel-group, clinical trial. Children were randomly assigned to three groups. SETTING: Health Districts in the north-west of England with high levels of dental caries. Clinical examinations were performed in schools during the period October 1999 to April 2000 when the children were 5-6 years old. PARTICIPANTS: Children from 3-month birth cohorts resident in nine, nonfluoridated health districts. INTERVENTIONS: Toothpaste containing either 440 or 1450 ppm F and dental health literature posted at 3-month intervals and toothbrush provided annually from the age of 1-5 years. Comparison group received no intervention. MAIN OUTCOME MEASURES: Mean dmft and proportion of participants with dmft > 0, dmft > or = 4, upper primary incisor caries and extraction of one or more primary teeth. Outcomes tabulated for quartiles of participants based on the distribution of the Townsend index of material deprivation. RESULTS: A total of 3467 children were included in the final data analysis. The Townsend index was found to be useful in identifying groups of children with increased caries risk. Overall, participants in the programme using the high-fluoride toothpaste had significantly (P < 0.002) less caries than the comparison group with similar absolute reductions in mean dmft for the most- and least-deprived groups. Relative to the comparison group the association between deprivation and dental caries was changed so that in the most-deprived quartile those using the low-fluoride toothpaste tended to have less dental caries than the comparison group whereas in the least deprived they tended to have more. This difference in the association (slope) was statistically significant (P < 0.05). Provision of both low- and high-fluoride toothpaste appeared to reduce the risk of extractions for participants in the most-deprived quartile (P < 0.05). CONCLUSION: The relative benefits of the programmes supplying the two toothpastes considered in this study are different depending on the deprivation status of the participants. For the most-deprived groups postal provision of either a low- or high-fluoride toothpaste provides similar levels of benefit. In the less deprived groups only provision of the high-fluoride toothpaste provided a benefit. The absolute caries reduction seen for provision of the high-fluoride toothpaste was not related to the deprivation status and hence the programme did not reduce deprivation-related health inequalities. Targeting the programme using the methods employed in this study is unlikely to improve the effectiveness of the programme.

Predictors of outcome for orofacial pain in the general population: a four-year follow-up study.

Orofacial pain is often persistent, but it is not clear why it lasts in some patients but not in others. We aimed to describe the natural course of orofacial pain in a general population sample over a four-year period and to identify factors that would predict the persistence of pain. A cross-sectional population-based survey was conducted in the United Kingdom, involving 2504 participants (participation rate 74%), of whom 646 (26%) reported orofacial pain. Overall, 424 (79% adjusted participation rate) of these individuals participated at the four-year follow-up, of whom 229 (54%) reported orofacial pain and 195 (46%) did not report such pain. Persistent orofacial pain was associated with females, older age, psychological distress, widespread body pain, and taking medication for orofacial pain at baseline. These findings may have implications for the identification and treatment of patients with orofacial pain.

Parental attitudes to the care of the carious primary dentition.

OBJECTIVES: To examine parents' attitudes to the dental care of their children, taking into account the family's socio-economic background, dentally-related behaviour including the child's level of dental anxiety and dental treatment history. METHODS: A cross sectional study of all 5-year-old children living in Ellesmere Port and Chester. All children were clinically examined; dmft and its components were recorded. A postal questionnaire was sent to the children's parents to measure their preferences for dental care with reference to two scenarios, (1) if their child had a carious but asymptomatic primary tooth, or (2) if their child had a carious primary tooth which was causing toothache. Parents were also asked to provide information on the dental attendance pattern of their child and an assessment of their child's dental anxiety. Family socio-economic status was recorded using the Townsend material deprivation index of the electoral ward in which they resided. RESULTS: Questionnaires were distributed to the home addresses of the 1,745 children who were clinically examined, and 1,437 were returned, giving a response rate of 82%. In both scenarios the majority of parents were happy to leave the decision on treatment to the dentist. In the asymptomatic tooth scenario, approximately one third of parents wanted the tooth to remain untreated but periodically monitored, only 6% expressed a desire to have their child's tooth restored. Multivariate analysis showed that parents of children who had a filling (OR 4.32 95%CI 2.21-8.43) or extraction (OR 2.24 95%CI 1.11-4.53) in the past were significantly more likely to want restorative care for their children. In the scenario where the child had toothache, multivariate analysis confirmed that parents had a preference for an intervention (extraction or filling) if they lived in a deprived area (Townsend score OR 1.10, 95% CI 1.04, 1.16) or if their child had had an extraction (OR 4.35, 95% CI 1.59, 11.88) or filling (OR 2.39, 95% CI 1.05, 5.45) in the past, after controlling for gender, attendance and parentally reported anxiety. When preference for an extraction was considered as the dependent variable, there was no significant relationship with past restorative treatment. In both scenarios there was no association between parentally reported anxiety of the child and parental preferences for treatment. CONCLUSIONS: In this part of the UK, there was little explicit support amongst parents for the restoration of asymptomatic carious primary teeth. Parental expectations for the dental care of young children with caries in their primary teeth, were closely related to the treatment experiences of the child. Families living in deprived areas expressed a preference for more interventionist care than their more affluent counterparts. Parentally judged anxiety of the child or their past dental attendance behaviour had no association with parents' preferences for the care of their children.

A cluster randomised, controlled trial of the value of dental health educators in general dental practice.

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 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.
