The Queen Mary Cavity Free Incremental Children s Programme Programme Overview Oral diseases are preventable and treatable, yet national oral health surveys clearly show that children s oral health is still a significant public health problem in the UK. Almost a third (30.9%) of five year old children had experienced dental decay in 2007/2008 while 27.5% of five year olds had untreated decayed primary teeth (1, 2). Only 18% of five year olds with decay had had their teeth filled (1). Similarly, 33.9% of 12 year old children in the UK in 2008/09 had at least one decayed or filled permanent tooth or a permanent tooth extracted because of dental decay (3). Less than 50% (47%) of 12 year olds had had their decayed permanent filled. Untreated decay is the main cause of toothache and significantly affects children s ability to sleep, eat, and speak (4). Preventing dental decay and improving the quality of oral health care for children in the UK should be a commissioning priority in line with the recently published White Paper Healthy Lives, Healthy People: Our Strategy for Public Health in England (5). This paper underscored the Government s renewed commitment to oral disease prevention and evidence based oral health care specifically focused on children s oral health (5). Developing an effective oral health strategy that includes early preventive interventions and evidence based treatment modalities will have long term benefits for children reducing the need for future costly and more extensive dental treatment as children age through the life course from childhood to adulthood. There is a clear need for change. A dental public health approach is required to address the key issues related to the low uptake of preventive services and the inadequate provision of cost effective high quality dental treatment for children in the UK. Hence, we propose a new programme The Queen Mary Cavity Free Incremental Children s Programme. This school and practice based partnership will provide high quality dental care including the assessment of risk, appropriate evidence based treatment modalities, preventive dental services tailored to the risk level of each child and 1
continuing care with evaluated quality assurance. In addition, it will encourage pupil s family practice link. It will incorporate evidence based treatment and preventive services including the Atraumatic Restorative Treatment (ART), fissure sealants, topical fluorides varnish, and oral health education as recommended by the Department of Health, Delivering Better Oral Health: An evidence based toolkit for prevention (6). This incremental programme will target Year 2 children in the first year and include an additional new cohort every subsequent year (Figure 1). It uses an incremental approach that will avoid the high cost of attempting to treat the whole school child population with high levels of untreated decay immediately. Instead, it will distribute the total cost of treatment in year cohorts, treating only the 6 7 year old children cohort in the first year, adding additional cohorts of the same age in subsequent years. Adopting an early intervention strategy to identify children at risk when the first permanent molar teeth erupt will prevent dental decay, or arrest/treat decay in its earliest stages. This highly cost effective approach will follow up each cohort to monitor their risk level (Table 1), ensure continuity of care, and dramatically reduce the likelihood that children will have large cavities in their permanent teeth, which are costly to treat. Therefore, this programme will ultimately allow PCTs to use cost effective, long term cost saving, and continuing care based on preventive and less destructive treatment approaches that will preserve healthy tooth tissue, increasing the likelihood that people keep their teeth for life (7).

School dental screenings will first categorize Year 2 children into three risk groups, which will determine the core services prescribed for each child. All children will receive tailor made health care depending on their risk. All children will receive health education irrespective of their disease risk. If resources permit, moderate and high risk children will receive additional core evidence based preventive dental services namely fissure sealants, and fluoride varnish applications. Alternatively, only high risk children will receive these preventive services. High risk children will have decay in at least one of their first molars (Table 1), and will receive ART. The ART is a minimally invasive approach used to treat open cavities involving dentine in primary and permanent molar teeth. The ART uses hand instruments rather than mechanical drills to remove dental decay from open cavities, which avoids the need for local anaesthesia (reducing dental anxiety and pain (8, 9), expensive equipment and designated dental clinics (10). Cavities are then restored with Glass Ionomer Cement (GIC), a filling material that adheres to tooth tissue and releases fluorides into the tooth (7). The adhesive restorative material also seals the remaining pits and fissures at risk of decay. This early intervention can successfully arrest decay in children. The ART has a strong evidence base supporting its effectiveness for restoring small cavities in permanent (adult) teeth (8, 10, 11). Systematic reviews have demonstrated the long term benefits of ART, reporting no difference between the long term survival of conventional amalgam restorations and GIC restorations over a two year period (12 15). Four randomized control trials showed that ART GIC restorations had higher success rates than amalgam restorations (12). A South African study reported a 17.4% reduction in permanent teeth extractions resulting from ART over a one year period. We can anticipate significantly larger impacts and absolute reductions in extraction and cavity rates among UK children who have greater access to dental care and lower decay experience. The ART approach also reduces the overall cost of dental treatment because of the lower equipment and operational costs for ART compared to traditional restorative treatment (16). Topical fluoride varnish applications and fissure sealants applied to first permanent molars will adhere to the Department of Health s preventive toolkit recommendations and national clinical guidelines (6, 17). Topical fluoride varnish prevents dental decay by optimizing fluoride exposure which makes tooth surfaces more resistant to acid attack (2) Systematic reviews show that twice yearly 3
applications of 2.2% fluoride varnish applied to early decay tooth surfaces reduce decay by up to a third (18 20). The Department of Health preventive toolkit (6) supports the evidence base by recommending that children identified as high risk (Moderate/high risk Table 1) receive three applications of fluoride varnish (2.2%) annually. The occlusal (biting) surfaces of permanent teeth are the most susceptible sites for decay confirmed in the UK Children s Dental Health Survey in 2003 (21, 22). Fissure sealants help to prevent decay by sealing these deep fissures molar teeth with a plastic resin coating. Systematic reviews show that children who have had their molar teeth covered with a resin based fissure sealant are less likely to suffer from dental decay in their molar teeth than children without sealants (23, 24). The long term effectiveness of fissure sealants has been demonstrated by caries reduction rates ranging from 86% at 12 months to 57% at 48 to 54 months (23). The Department of Health prevention toolkit (6) recommends that children at risk of developing decay in their permanent teeth should have fissure sealants placed on all susceptible teeth and sites. 4
