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.

Dental health knowledge and attitudes of regularly attending mothers of high-risk, pre-school children.

AIM: The aims of this study were to discover the knowledge of and attitudes towards dental health of a group of regularly attending mothers of young children at high-risk of caries, and to evaluate their toothbrushing techniques. METHOD: As part of the baseline examination of a randomised controlled trial to test the influence of dental health counselling on the caries increment of at-risk pre-school children, 268 mothers of 334 children completed a questionnaire enquiring about their dental health knowledge and attitudes, and were also observed brushing their children's teeth. RESULTS: Although most mothers (71%) knew that they should brush their children's teeth twice a day using a small toothbrush (94%) only 52% knew that they should use only a small pea-sized amount of paste, and only 3% knew the recommended level of fluoride in toothpaste for these at-risk children. 40% of the children insisted on brushing their own teeth and 40% of the mothers brushed their children's teeth inadequately. Although three-quarters of the mothers knew that sugary foods and drinks should be consumed only at mealtimes, only 7% knew the four foods and drinks supplying most sugar to a child's diet. Although three-quarters of mothers thought that dental decay in milk teeth was very important, only half wanted their children's carious teeth restored. CONCLUSION: Knowledge, attitudes and behaviour about dental health among these regularly attending mothers of at-risk, pre-school children were superficial. Their attitudes to dental health of primary teeth were equivocal and their demonstrated brushing behaviour on the part of their children was inadequate.

An evaluation of a training programme in primary care research for general dental practitioners.

AIMS: To determine whether general dental practitioners would find seminars on research methods in primary care research of interest and whether they would be stimulated to plan their own research. METHOD: Questionnaire with both open and closed questions distributed to participants at the end of the seminars. 10 seminars in locations throughout the north west of England were planned. RESULTS: 98 dentists attended the seminars of whom 81 returned questionnaires, giving a response rate of 82.6%. More than 60% found the seminars and the specially developed teaching manual very useful. However there was somewhat less enthusiasm for undertaking research projects. CONCLUSIONS: The findings suggest that some GDPs are interested in primary care research but are not keen to initiate or plan research themselves.

An investigation of the effects on children of tooth extraction under general anaesthesia in general dental practice.

OBJECTIVE: To describe the morbidity related to general anaesthesia provided in general dental practices for the extraction of teeth in school children. DESIGN: Observational study supported by structured questionnaires and interviews. SETTING: Three general dental practices in a Lancashire health district and children's homes. SUBJECTS: 80 children aged 5-15 years undergoing extractions under general anaesthesia. MAIN OUTCOME MEASURES: Observed demeanour of the children prior to, during and immediately after the surgical procedures. Reported morbidity during the following 24 hours and 1 month later. RESULTS: 92% of the children complained of symptoms associated with the surgery under general anaesthesia. Distress was noted in 16 (20%) patients during the induction of 26 (33%) during recovery. Continued crying was reported for 24 (39%) during the journey home and for 23 (37%) once home had been reached. Other symptoms included nausea, vomiting, sickness and prolonged bleeding. Six reported psychological trauma 1 month after; three had nightmares, two had continuing bad memories and one was depressed for several days. CONCLUSION: Morbidity following extractions under general anaesthesia in general dental practice is common and has distressing consequences for the young patients and their carers.

Levels of restorative care under capitation.

OBJECTIVES: 1. To compare the prevalences of fissure sealants in similar groups of 14-15-year-old, regularly-attending patients treated under fee-for-service in 1989 and capitation in 1994. 2. To calculate the effect of including sealants in the restorative index on estimates of interventional treatment carried out on 14-15-year-old regularly attending patients treated by general dental practitioners in 1994. DESIGN: A randomised epidemiological study. SETTING: Secondary schools in the Wycombe, Doncaster and Hereford/Worcester areas. METHOD: Random samples of 14-15-year-old, regularly attending patients treated by dentists practising under capitation in three contrasting areas of England were examined in 1994 for the presence of decayed, missing and filled teeth and fissure sealants. Restorative indices were calculated with and without the inclusion of sealants. The latter were compared with restorative indices calculated without the inclusion of sealants on regularly attending patients of the same age group when the dentists in the same three areas were working under fee-for-service in 1989. RESULTS: The prevalence of fissure sealants increased between 1989 and 1994 from 16% to 30% in Wycombe, from 13% to 50% in Doncaster and from 25% to 47% in Hereford/Worcester. Without fissure sealants the restorative indices fell between 1989 and 1994 from a range of 76.5-94.4 to 63.3-87.1. When sealants were included in the restorative indices for 1994, they ranged from 79.5-92.9. CONCLUSIONS: There were increases in the prevalences of fissure sealants between 1989-1994. When these sealants were included in the calculation of restorative indices for 1994, the level of restorative care provided by general dental practitioners remained relatively high since the introduction of capitation. Although there has been some increase in the level of untreated disease, if the restorative index is calculated without the inclusion of sealants then there is a risk of underestimating the treatment provided by general dental practitioners to control the carious process. Dentists appear to be redirecting their efforts into newer treatment/preventive items.

Development of a classification and index of dental treatment experience for adults.

OBJECTIVE: To develop and evaluate a classification and index of dental treatment experience for adults. DESIGN: Twenty-four general dental practitioners recorded treatment experience at baseline on 4,211 regularly attending adults of whom 3,878 were re-examined after one year and 3,698 patients completed a questionnaire on factors related to treatment. SETTING: Health authorities of Manchester and Salford. METHOD: Set theory was used to divide the baseline clinical data set into 7 mutually exclusive classes of dental treatment experience. Seven dental specialists used the nominal group technique to weight tooth status to form an index of dental treatment experience (DTE). The ability of the DTE classification and index to discriminate between groups of patients' responses to the questionnaire was compared with the THI and DMFT index. RESULTS: Ninety-nine per cent of the patients fell into 5 hierarchical classes ranging from fillings only to wearing a denture in addition to a crown and/or bridge. When calculated on the baseline data, the classification discriminated between 16 of the 20 variables investigated in the questionnaire. Fifteen significant differences were found between mean scores for groups of patients on the DTE index, 14 on the THI and 8 on the DMFT index. Fifty-five (1%) patients moved their class as a consequence of the treatment carried out during the year. All three indices found significant differences for the same four variables of the 20 tested. CONCLUSION: A classification of dental treatment experience together with an index to measure the severity of that experience has been successfully developed and tested. It appears to have advantages over the traditional DMFT index and is at least as discriminating as the THI.

An assessment of capitation in the General Dental Service contract 2. Patterns of treatment provided to regularly attending patients.

OBJECTIVE: To compare the patterns of treatment of general dental practitioners working under fee-for-service in 1987/88 with those working under capitation in 1992/93. DESIGN: 73 randomly selected general dental practitioners working under capitation in three contrasting areas in England retrospectively recorded the treatment provided during 1992/93 to a random selection of their regularly attending 6-12- and 14-15-year-old patients. RESULTS: Mean numbers of examinations per year reduced in the three areas from 1.7-1.8 in 1987/88 to 1.2-1.4 in 1992/93. Mean numbers of visits per patient dropped from 2.5-2.9 to 1.8-2.2. Mean numbers of fillings in permanent teeth reduced from 0.15-1.04 to 0.09-0.52 and in deciduous teeth from 0.28-0.53 to 0.24-0.31. Mean percentages of children per dentist having extractions fell from 9.3-28.1% to 4.7-16.2% while the radiographs reduced from 14.0-9.0% to 6.0-10.6%. Mean percentages of children per dentist receiving oral hygiene instruction rose from 18-31% in 1987/88 to 26-33% in 1992/93. Dietary advice increased from 3-18% to 11-20% and fissure sealants from 3-6% to 3-12%. CONCLUSIONS: In 1992/93, dentists working under capitation were carrying out fewer examinations, fillings and extractions and were taking fewer radiographs for their regularly attending child and adolescent patients than dentists working under fee-for-service in 1987/88. These patients also attended less frequently for treatment but received marginally more preventive care and advice.

An assessment of capitation in the General Dental Service Contract. 1. The level of caries and its treatment in regularly attending children and adolescents.

OBJECTIVE: To assess the dental health of regularly attending 7-8- and 14-15-year-olds registered under capitation in 1994. To compare the dental health of regularly attending 14-15-year-olds registered under capitation in 1994 with regularly attending patients of a similar age treated under fee-for-service in 1989. DESIGN: Random samples of 7-8- and 14-15-year-olds. Data were recorded on decayed and filled teeth, extracted for caries and teeth fissure sealed. RESULTS: Prevalence of caries in first permanent molars of 7-8-year-olds was 15-16%. Mean caries experience of deciduous posterior teeth was 1.78-2.51. 83-86% had no more than two untreated, decayed, posterior deciduous teeth. Prevalence of caries in 14-15-year-olds was 44-60% while mean caries experience was 1.29-1.83. Reductions in caries experience of 30-39% in 14-15-year-olds for 1989-1994 were due mainly to falls of 42-45% in mean numbers of teeth filled. Increases in mean numbers of decayed, untreated teeth were 0.07-0.11. The proportion of patients with teeth extracted because of caries was 2.4-3.8%. 30-50% had fissure sealants in 1994 compared with 13-25% in 1989. CONCLUSIONS: Dental health of regularly attending capitation patients is generally satisfactory with little evidence of 'supervised neglect'. Prevalence of fissure sealants has increased while the numbers of filled teeth has reduced. Numbers of decayed, untreated teeth have increased but the numbers of teeth extracted for caries have remained low.

An investigation of dento-alveolar trauma and its treatment in an adolescent population. Part 2: Dentists' knowledge of management methods and their perceptions of barriers to providing care.

AIM: To assess dentists' knowledge of and perceived barriers to treatment of dental injuries. DESIGN: Cross-sectional postal questionnaire and personal interview. SUBJECTS AND METHODS: Questionnaires from 153 GDPs and 53 CDOs were received giving details of emergency options on 17 imaginary dental injuries and perceived barriers to treatment of trauma. Structured interviews with 21 of the GDPs and 19 CDOs seeking knowledge on diagnosis and long-term follow-up and treatment took place. Age and gender of dentist, type of practice and postgraduate courses attended were noted. MAIN OUTCOME MEASURES: Mean knowledge scores. RESULTS: Of a maximum of 14 correct responses on emergency treatment of injured teeth the mean was 7.5. Only 19% knew for how long avulsed teeth should be splinted. Of a maximum of 37 correct responses on long-term follow-up of treatment the mean was 15.4. Only 10% would correctly treat acute abscess on a traumatised tooth. 82% of dentists thought dental trauma should be treated in the primary care service, but 86% of GDPs thought fees for this type of treatment were too low. 72% of CDOs thought the treatment occupied too much clinic time and was not the responsibility of the CDS. CONCLUSIONS: Dentists in the primary care sector have insufficient knowledge to treat dental trauma.

An investigation of dento-alveolar trauma and its treatment in an adolescent population. Part 1: The prevalence and incidence of injuries and the extent and adequacy of treatment received.

AIM: To measure the prevalence and incidence of dental trauma and to assess the extent and success of treatment provided. DESIGN: Cross-sectional and one-year incremental study. SUBJECTS AND METHODS: 2022 11-14-year-old pupils were examined in schools for clinical evidence of trauma of anterior teeth. 1891 were examined 15 months later. A history of the trauma and treatment provided were obtained together with some social data. Radiographs were taken of affected teeth. MAIN OUTCOME MEASURES: Degree of trauma, whether treatment was provided and its quality, ACORN classification. RESULTS: 34% had suffered trauma but only 12% needed treatment for 332 teeth. 47% of these teeth had received treatment, of which 59% was inadequate. After 15 months 4% had experienced new injuries. 42% of boys and 28% of girls (P < 0.01) had sustained injuries, as had 38% from ACORN group III and 30% from groups I and II. 67% of those with pain and 40% of those without attended for treatment (P < 0.01), while 69% who were unhappy with the appearance and 35% who were not (P < 0.01) attended. CONCLUSIONS: The primary care services currently available for the treatment of dental trauma are inadequate.

Preventive technologies in dental practice in the UK.

Visits were made to 26 selected general dental practices in Greater Manchester, UK to record the preventive technologies used on 106 patients below the age of 18 years. In addition, the patterns of treatment of 72 general dental practitioners in three contrasting areas in England were recorded, 11 of whom used preventive dental units. No relationship could be found between the organisation of the practice and the amount or type of prevention supplied or the patterns of treatment provided. The value of the preventive technologies currently offered in general dental practice is questioned and further research is recommended to discover the best model of practice to achieve cost-effective prevention.
