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.

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 fate of the carious primary teeth of children who regularly attend the general dental service.

OBJECTIVE: To describe the care and resultant outcomes of the carious primary teeth of children who regularly attend the General Dental Service (GDS). SETTING: Four districts in the North West of England SUBJECTS AND MATERIALS: A retrospective study of the case notes of 677 children who received their dental care from 50 general dental practitioners (GDPs). Each dentist must have had a minimum of 10 patients and a maximum of 20 patients whose care had been provided by the same dentist from or before the age of five to the age of 14. All of the children included in the study had a history of approximal caries. The outcomes of interest were extraction due to pain or sepsis, or exfoliation and whether or not a tooth had given rise to the prescription of a course of antibiotics. Teeth that did not have a history of extraction were assumed to have exfoliated naturally. Logistic regression models, taking into account the clustering of the teeth within patients, were fitted to compare the outcomes for restored and unrestored teeth according to size of lesion (one or two surface), age caries was first recorded and by tooth type. RESULTS: A total of 4,056 teeth had been either recorded as carious or had received an intervention of some kind. Some 44.1% (N=1,789) of these teeth were extracted, however only 475 (11.7%) were extracted due to pain or sepsis. Of the teeth with a documented history of caries or restoration and for which an outcome was recorded (N=3,145), most first (81.1%) and second (84.3%) carious primary molars were filled during their lifetime, but only 40.5% of primary carious anterior teeth were filled. The majority of carious primary teeth exfoliated naturally. There was no difference in the proportions of teeth extracted due to pain or sepsis whether a carious tooth was restored or left unrestored, either by cavity type or by tooth type, after controlling for age when caries was first recorded. There was also no difference in the number of filled or unfilled carious teeth that caused a course of antibiotics to be prescribed. CONCLUSIONS: Treatment by extraction was common, but GDPs restored the majority of carious primary molar teeth of their regularly attending child patients. The bulk of carious teeth exfoliated naturally irrespective of whether they were filled or not. The reasons for these findings require further investigation.

Dental caries, contact with dental services and deprivation in young children: their relationship at a small area level.

OBJECTIVE: To measure the relationship between tooth decay, contact with dental services and deprivation at electoral ward level. SETTING: The study was carried out in 1998 in Ellesmere Port in the North West of England. SUBJECTS AND MATERIALS: All children younger than six years resident in Ellesmere Port registered with GDS services and those using CDS services were matched against the HA population register to identify unregistered children. Rates for children aged 3-5 years 'in contact' with primary dental care services, whether CDS or GDS, were calculated at ward level. One calibrated examiner examined all 5-year-old children in Ellesmere Port and dmft scores were calculated at ward level. Ward deprivation was measured using the Jarman score. Bivariate linear regressions at ward level were performed in turn between: dmft and Jarman score; rates for 3-5-year-olds in contact with dental services and Jarman score; and dmft and rates for 3-5-year-olds in contact with dental services. RESULTS: A significant linear relationship was observed between dmft and Jarman score (P=0.02, R2 = 0.43). Significant inverse relationships were found between rates for 3-5-year-olds in contact with dental services and Jarman score (P=0.001, R2 = 0.67), and also between dmft and rates for 3-5-year-olds in contact with dental services (P=0.002, R2 = 0.65). CONCLUSIONS: A strong inverse relationship was found between dental caries and contact with primary dental care services at electoral ward level. This relationship needs to be explored over a wider geographical area to establish if it is consistent and independent of deprivation.

Socioeconomic and geographical influences on primary dental care preferences in a population of young children.

OBJECTIVE: To compare the socioeconomic profiles of children registered in the GDS, with those using the CDS services and unregistered children. Secondly to examine the effects of socioeconomic status on travelling to access primary dental care, and finally to map out the location of unregistered children in relation to primary dental care services. SETTING: The study was carried out in 1998 in Ellesmere Port in the North West of England. SUBJECTS AND MATERIALS: The study population was all children younger than 6 years who used primary dental care services in, or were residents of, Ellesmere Port. The study population was categorized into those registered with a GDS dentist, those using CDS services and those unregistered by matching GDS and CDS data to the HA population register. Socioeconomic status was measured using the Super Profiles geodemographic classification. The relationship between service preferences and travelling to access primary dental care with socioeconomic status were compared using cross-tabulations and chi square tests. RESULTS: There was a significant socioeconomic trend evident in the use of dental services. Two thirds of those using CDS services came from the most deprived area types. Of those who were unregistered half lived in the most deprived area types compared with one third of those registered with the GDS. Those who travelled into Ellesmere Port to access primary dental care were significantly more likely to live in an affluent area. Unregistered patients were homogeneously spread across the town. CONCLUSIONS: The ability to match GDS and CDS data to the HA population register is essential to understand how dental services are used by the local population. Children from deprived areas are more likely to use the CDS and a service local to their homes, therefore primary dental care services for deprived communities have to be provided locally.

The identification of agreed criteria for referral following the dental inspection of children in the school setting.

AIM: To clarify the function of the school based dental inspection. OBJECTIVE: For representatives of the Community Dental Service, General Dental Service and Hospital Dental Service to identify an agreed set of criteria for the referral of children following school dental inspection. DESIGN: Qualitative research methodology used to establish a consensus for the inclusion of referral criteria following dental screening. SETTING: Ellesmere Port, Cheshire, England. MATERIALS: A Delphi technique was used to establish a consensus amongst the study participants on the inclusion of nine possible criteria for referral following dental screening. All participants scored each criterion in the range 1-9, with a score of 1 indicating that referral of individuals with the condition should definitely not take place, and a score of 9 indicating referral should definitely take place. Referral criteria were accepted only if they achieved a group median score of 7 or more, with an interquartile range of three scale points, with the lower value being no less than 7. RESULTS: Four of the nine possible criteria met the agreed group standard for inclusion: 'Sepsis', 'Caries in the secondary dentition', 'Overjet > 10 mm', and 'Registered & caries in the permanent dentition'. CONCLUSION: It is possible to agree clear criteria for the referral of children following the school dental inspection.

Is it better to leave or restore carious deciduous molar teeth? A preliminary study.

INTRODUCTION: The objective of this study was to compare the extraction and exfoliation experience of filled and unfilled carious deciduous molar teeth. METHOD: The study was carried out in 1997 in four general dental practices in south Cheshire, UK and involved a longitudinal retrospective review of case notes. A quota sample of 20 case notes of children from each practice was selected according to strict criteria. Subjects had to: Have had experience of approximal caries in one or more of the deciduous molar teeth. Have a date of birth between 1st January 1984 and 31st December 1985. Be a regular attender and in continuous contact with the practice. Data were collected on a common data abstraction form. Variables measured included: Base-line dmft. Site and number of filled teeth. Site and number of unfilled carious teeth. Number of courses of antibiotics. Site and number of pulp therapies. Site, number, method (local or general anaesthetic) of extractions. Reasons for extraction. All teeth not recorded as being extracted were assumed to have exfoliated. In addition, information was collected on the dentists' treatment philosophies. A series of group discussions revealed that the four dentists fitted into two groups according to treatment philosophies; two dentists shared a philosophy of minimal intervention, the other two shared the same views of treating more radically. RESULTS: There was no significant difference between the proportion of filled teeth and the proportion of carious unfilled teeth that were extracted (chi-square 0.05 P = 0.83). A logistic regression showed that for each course of antibiotics administered the odds of having an extraction was multiplied by 5.5 and children who were patients of the interventionist dentists were five times more likely to have an extraction than patients of non-interventionist dentists. CONCLUSION: Although the study was preliminary in nature no clear benefit could be found in filling deciduous molar teeth against leaving carious teeth unfilled, if avoidance of extraction was the desired outcome. The treatment philosophy of dentists was a major factor in determining extraction or exfoliation outcomes. This issue is complex with many interacting factors to be accounted for and will require multiple well-designed studies to provide an answer.

Enamel defects in 8-year-old children in fluoridated and non-fluoridated parts of Cheshire.

The aim of this study was to compare the prevalence of developmental defects of enamel in fluoridated (1 ppm F) and non-fluoridated (less than 0.2 ppm F) communities in Cheshire, England. Eight-year-old children were examined under blind conditions. Only lifetime residents were included and only children with no history of dietary fluoride supplements. Significantly more children living in the fluoridated community (60%) had enamel defects compared to those in the non-fluoridated community (44%). In the fluoridated community, significantly more children whose parents claimed to begin brushing at an early age exhibited enamel defects.
