Preventing Caries With Silver Diamine Fluoride

Background: Early childhood caries (tooth decay, ECC) affected 55% 5-year-old Hong Kong children, and 70% of these children had gross destruction of the upper anterior teeth with negative long-term impacts on health and quality of life. The existing standard of care for prevention of ECC, topical application of 5% sodium fluoride (NaF) varnish, is inadequate. In Hong Kong and other parts of the world, 38% silver diamine fluoride (SDF) solution, applied topically to cavities, is used to arrest ECC. Work published by our research group suggests it likely also has a preventive effect of ECC. Moreover, SDF has been shown to be preventive in tooth decay in permanent teeth. Nevertheless, no pivotal clinical trial has been performed to support a change in usual practice. Aim: This is a Phase II single-centre randomized, double-blind, active-controlled, parallel-group pragmatic trial with two arms to assess the effectiveness of 38% SDF to determine if it is superior to 5% NaF in preventing new caries lesions in primary anterior teeth. Methods: Approximately 700 three-year-old kindergarten children who are healthy will be recruited, stratified by school, and block randomized to receive either 38% SDF (treatment group) or 5% NaF (standard treatment group) therapy on primary upper anterior teeth. This sample size is sufficient for a superiority trial with power at 90%, allowing for a 15% dropout rate. The primary outcome is the number of sound tooth surfaces that become cavitated caries per child at 12-month follow-up. The secondary outcome is the number of carious tooth surfaces developed after baseline that become arrested at 12-month for each child. Dental examinations for the status of caries (active or arrested) will be conducted by the same calibrated examiner. The examiner, children and children's parents will be blind to treatment allocation. Parents will be surveyed to study the children's oral health-related behaviours and socioeconomic backgrounds, which will allow the adjustment for effect modification. Possible results and implications: If the results are as anticipated, it will help change the standard of care for caries prevention. If adopted in Hong Kong, SDF therapy will prevent 20,800 (13% of the 160,000) kindergarten children from having caries developed in their anterior teeth, thus reduce significantly the burden of ECC of the children and related stress of their family. Moreover, the results will be widely available and increase adoption of SDF in other countries to reduce the global burden of ECC among children.

Preventing Early Childhood Caries With Silver Diamine Fluoride

Background: Silver diamine fluoride (SDF) solution is effective in arresting early childhood caries (ECC). Previous studies suggested that it might exert a preventive effect in managing ECC. However, no well-designed clinical trial has been performed to study this topic. The aim of this randomised clinical trial is to assess whether 38% SDF is superior to 5% sodium fluoride (NaF) varnish in preventing new carious lesions in primary anterior teeth. Methods/Design: This is a Phase II single-centre randomized, double-blind, active-controlled, parallel-group pragmatic trial. The hypothesis tested is that 38% SDF is more effective than 5% NaF in preventing new caries development in primary anterior teeth. Approximately 2,100 three-year-old kindergarten children who are generally healthy and with parental consent will be recruited. This sample size is sufficient for an appropriate statistical analysis of superiority trial with power at 80%, allowing for a 15% drop-out rate. Stratified randomization will be adopted for the intervention allocation. The intervention is either 38% SDF or 5% NaF (as positive control) therapy on primary upper anterior teeth. Dental examination followed by fluoride therapy will be conducted every six months until 30 months in kindergartens by a single examiner. The examiner, children and children's parents will be blinded to the treatment allocation. Questionnaire survey will be conducted to study the children's oral health-related behaviours and their socioeconomic backgrounds. Discussion: The effectiveness of 38% SDF in preventing ECC remains uncertain. If the results are as anticipated, it will help change the standard of care that using 5% NaF for ECC prevention. In addition, the results will be widely available and increase adoption of SDF in other countries to reduce the global burden of ECC.

Obesity and Oral Diseases in Adult Patients

Overweight and obesity are among the major chronic disorders of the 21st century and one of the fastest growing health problems worldwide. Obesity is accompanied by a state of low-grade inflammation which may contribute to the occurrence of diabetes mellitus, cardiovascular disease, hypertension, stroke, and certain cancers. Furthermore, obesity has been associated with oral health problems as hyposalivation, dental caries and periodontitis. The management and treatment of obesity is outlined in clinical guidelines from American Association of Clinical Endocrinologists/American College of Endocrinology and European Association for the Study of Obesity. The cornerstone is life-style modification programs aiming to reduce energy intake and increase physical activity, referred to as conservative treatment. All patients must undergo a thorough systematic work-up. The work-up concludes in a final multi-disciplinary meeting with a concrete individualized plan on how sustained weight-loss is to be achieved; either by a non-surgical or a surgical approach (Bariatric surgery). Periodontitis is cited to be the sixth most prevalent chronic condition globally. The mechanisms by which obesity affects the periodontal tissues is poorly understood, and the understanding of the key role of adipocytes in the inflammatory response to infections is crucial in comprehending how periodontal disease susceptibility may be modified in obese individuals. The main objectives of the present research project are to explore the association between obesity and oral diseases and further, to assess how weight changes following non-surgical and surgical interventions of obese patients may affect the cariological and periodontal health status. Four hundred patients referred to the Obesity Centre at Haukeland University Hospital, Norway will consecutively be screened and invited to participate in this prospective cohort study. At baseline, detailed medical and oral data will be obtained from health forms, questionnaires, clinical examinations, and by consulting the patient's care team. Following baseline examination, all patients will undergo a thorough systematic work-up consisting av interviews and consultations concluding in a final multi-disciplinary individualized non-surgical or surgical treatment plan on how sustained weight-loss can be achieved. New sets of medical, oral, and molecular data will be collected at 3-, 12- and 18-month following non-surgical/surgical interventions.

Providers Against Cavities in Children's Teeth

The study is a multi-site, multi-level, and multi-component cluster randomized clinical trial (RCT) to address poor dental utilization (attendance) and untreated caries among 3-6 year old Medicaid-enrolled children attending well-child visits (WCV) in primary care settings. The focus is on addressing factors (determinants) at the socio-ecological levels of the child's environment: provider (pediatrician and nurse practitioner), practice/organization level, and parent/caregiver level. Eighteen practices will be randomized to 2 arms: A) bundled multi-level intervention consisting of: 1. training medical providers in the Common-Sense Model of Self-Regulation theory-based education so that the provider delivers to the parent/caregiver the following: i) Core oral health facts about dental caries, and ii) prescription to visit the dentist and a list of dentists accepting Medicaid; 2. Integration of oral health assessments into EMR for the provider to document in the child's medical record; versus B) Control arm of medical providers receiving the American Academy of Pediatrics (AAP) based oral health education and providing usual AAP-based care for oral health. Each arm will consist of 9 practices. Children will be followed for 24 months to determine dental utilization and changes in oral health status. The primary aim is to examine the effectiveness of theory-based behavioral (provider-level) and implementation (practice-level) bundled interventions versus enhanced usual care (AAP based oral health education) delivered by providers at WCVs in increasing dental attendance among 3-6 year old Medicaid-enrolled children. The secondary aims are to 1) assess the effectiveness of interventions on secondary outcomes (e.g. development of new caries, changes in oral hygiene, oral health quality of life, frequency of sweet snacks and beverages, cost), 2) assess potential mediators and moderators to investigate the pathways through which the multi-level interventions affect child primary and secondary outcomes, and 3) assess the adoption, reach, fidelity, and maintenance of providers and practices that affect child primary and secondary outcomes. The hypothesis is that theory-based behavioral (provider-level) and implementation (practice-level) bundled interventions delivered by providers at WCVs will increase dental attendance among 3-6 year old Medicaid-enrolled children versus enhanced usual care (AAP based oral health education) delivered by providers at WCVs.
