Periodontal disease as a possible cause for Alzheimer's disease
Kamer, Angela R; Craig, Ronald G; Niederman, Richard; Fortea, Juan; de Leon, Mony J
Approximately 47 million people worldwide have been diagnosed with dementia, 60%-80% of whom have dementia of the Alzheimer's disease type. Unfortunately, there is no cure in sight. Defining modifiable risk factors for Alzheimer's disease may have a significant impact on its prevalence. An increasing body of evidence suggests that chronic inflammation and microbial dysbiosis are risk factors for Alzheimer's disease. Periodontal disease is a chronic inflammatory disease that develops in response to response to microbial dysbiosis. Many studies have shown an association between periodontal disease and Alzheimer's disease. The intent of this paper was to review the existing literature and determine, using the Bradford Hill criteria, whether periodontal disease is causally related to Alzheimer's disease.

School-based caries prevention and longitudinal trends in untreated decay: an updated analysis with Markov chains
Ruff, Ryan Richard; Saxena, Deepak; Niederman, Richard
OBJECTIVE:Dental caries (tooth decay) is the most prevalent childhood disease in the world. A school-based program for the prevention of dental caries providing bi-annual sealants, interim therapeutic restorations, and fluoride varnish to children aged 5-12 years was previously associated with a significant reduction in the prevalence of untreated tooth decay over time. The objective of this study was to explore potential nonlinear change in the risk of untreated decay in children receiving caries prevention. RESULTS:Across all study participants, there was a significant increase in the odds of untreated tooth decay over time (OR = 1.90, 95% CI 1.51, 2.39), but the rate of this risk rapidly decreased with each observational visit (OR = 0.87, 95% CI 0.93, 0.91). Overall effects substantially depended on the oral health status of participants at baseline: for children with untreated decay at their first observation, the odds of untreated decay over time was 0.39 (95% CI 0.27, 0.55). A quadratic change for this subpopulation showed that the per-visit decrease in decay was attenuated with each subsequent observation (OR = 1.12, 95% CI 1.04, 1.20).

A Dental Response to the COVID-19 Pandemic-Safer Aerosol-Free Emergent (SAFER) Dentistry
Benzian, Habib; Niederman, Richard
Dental services are significantly impacted by the COVID-19 pandemic. Almost all dental procedures carry a high infection risk for providers and patients due to the spread of aerosols. As a consequence, public health agencies and professional associations have issued guidelines for enhanced infection control and personal protection equipment and have also limited care to urgent or emergency services. However, there is no dental service concept for pandemic disaster preparedness or response that might be applied. Moreover, pathways to dental care provision in a post-pandemic future with persisting risks are needed. We propose Safer Aerosol-Free Emergent Dentistry (SAFER Dentistry) as one approach to dental services during and emerging from the pandemic. The concept's starting point is the identification of the most common patient needs. The next step is to replace common treatments addressing the most frequent needs with alternative interventions involving a lower infection risk because they do not generate aerosols. SAFER Dentistry is innovative, avoids risk, and responds to the requirements of a pandemic and post-pandemic emergency where the risk of airborne disease transmission remains high. SAFER Dentistry thereby ensures continuity of dental services while protecting providers and patients from infectious pathogens. Moreover, SAFER Dentistry allows dental service providers to remain operational and generate income even under pandemic conditions. Potential implementation and policy options for SAFER Dentistry include universal availability without co-payments by patients and a uniform bundled payment scheme for providers to simplify budgeting, reimbursement, and administration during a pandemic. Adaptations and adjustments of the concept are possible and encouraged as long as the principle of avoiding aerosol-generating procedures is maintained.

Quality Appraisal of Child Oral Health-Related Quality of Life Measures: A Scoping Review
Yang, C; Crystal, Y O; Ruff, R R; Veitz-Keenan, A; McGowan, R C; Niederman, R
BACKGROUND/UNASSIGNED:Children's oral health-related quality of life (COHQoL) measures are well known and widely used. However, rigorous systematic reviews of these measures and analyses of their quality are in absence. OBJECTIVES/UNASSIGNED:To systematically review and quantitatively assess the quality of COHQoL measures through a scoping review. DATA SOURCES/UNASSIGNED:Systematic literature search of PubMed, CINAHL (Cumulative Index to Nursing and Allied Health Literature), EMBASE (Excerpta Medica database), HaPI (Health and Psychosocial Instruments), and DOSS (Dentistry and Oral Sciences Source). STUDY ELIGIBILITY/UNASSIGNED:The measure's focus was COHQoL; the child age ranged from 5 to 14 years; the publication was either a research article or a systematic review and related to caries; and it was written in English or had an English abstract. Two authors independently selected the studies. Disagreements were reconciled by group discussions with a third author. APPRAISAL/UNASSIGNED:The International Society for Quality of Life Research minimum standards for patient-reported outcome measures were used for quality appraisal. SYNTHESIS/UNASSIGNED:Descriptive analysis. RESULTS/UNASSIGNED:We identified 18 measures. Their quality scores ranged from 9.5 to 15.0 on a scale of 16. The quality appeared to bear no relationship to the citation and use of these measures. However, elements of these measures might be more useful than others, depending on the age-specific use and primary quality concerns. LIMITATIONS/UNASSIGNED:Some of the information on the minimum standards of the 18 measures cannot be found in the existing literature. Measures published without English abstract were not searched. CONCLUSIONS/UNASSIGNED:The quality of these measures is suboptimal. Researchers and practitioners in this field should exercise caution when choosing and using these measures. Efforts at improving the quality of the COHQoL measures, such as refining existing ones or developing new measures, are warranted. KNOWLEDGE TRANSFER STATEMENT/UNASSIGNED:Researchers, clinician scientists, and clinicians can use the results of this study when deciding which oral health-related quality of life measure they wish to use in children.

An Economic Evaluation of a Comprehensive School-Based Caries Prevention Program
Huang, S S; Ruff, R R; Niederman, R
INTRODUCTION/UNASSIGNED:Current economic evaluations of school-based caries prevention programs (SCPPs) do not compare multiple types of SCPPs against each other and do not consider teeth beyond permanent first molars. OBJECTIVES/UNASSIGNED:To assess the cost-effectiveness of a comprehensive SCPP relative to an SCPP focused on delivering sealants for permanent first molars only and to a default of no SCPP. Based on a societal perspective, a simulation model was used that compared the health and cost impacts on 1) permanent first molars only and 2) all posterior teeth. METHODS/UNASSIGNED:To calibrate the model, we used data from CariedAway, a comprehensive SCPP that used glass ionomer to prevent and arrest active decay among children. We then evaluated the incremental cost-effectiveness of implementing 3 alternate school-based approaches (comprehensive, sealant only, and no program) on only first molars and all posterior teeth. Probabilistic, 1-, and 2-way sensitivity analyses are included for robustness. Cost-effectiveness is assessed with a threshold of $54,639 per averted disability-adjusted life year (DALY). RESULTS/UNASSIGNED:We first compared the 3 programs under the assumption of treating only first molars. This assessment indicated that CariedAway was less cost-effective than school-based sealant programs (SSPs): the resulting incremental cost-effectiveness ratio (ICER) for CariedAway versus SSPs was $283,455 per averted DALY. However, when the model was extended to include CariedAway's treatment of all posterior teeth, CariedAway was not only cost-effective but also cost-saving relative to SSPs (ICER, -$943,460.88 per averted DALY; net cost, -$261.45) and no SCPP (ICER, -$400,645.52 per averted DALY; net cost, -$239.77). CONCLUSIONS/UNASSIGNED:This study finds that economic evaluations assessing only cost and health impacts on permanent first molars may underestimate the cost-effectiveness of comprehensive SCPPs 1) preventing and arresting decay and 2) treating all teeth. Hence, there is an urgent need for economic evaluations of SCPPs to assess cost and health impacts across teeth beyond only permanent first molars. KNOWLEDGE TRANSFER STATEMENT/UNASSIGNED:The results of this study can be used by policy makers to understand how to evaluate economic evaluations of school-based caries prevention programs and what factors to consider when deciding on what types of programs to implement.

Evidence-Based Dentistry Update on Silver Diamine Fluoride
Crystal, Yasmi O; Niederman, Richard
This article reviews current evidence on the effectiveness of silver diamine fluoride (SDF) as a caries arresting and preventive agent. It provides clinical recommendations around SDF's appropriate use as part of a comprehensive caries management program. Systematic reviews confirm that SDF is effective for caries arrest on cavitated lesions in primary teeth and root caries in the elderly. It may also prevent new lesions. Application is easy, noninvasive, affordable, and safe. Although it stains the lesions dark as it arrests them, it provides clinicians with an additional tool for caries management when esthetics are not a primary concern.

The Effect of Silver Diamine Fluoride in Preventing Caries in the Primary Dentition: A Systematic Review and Meta-Analysis
Oliveira, Branca Heloisa; Rajendra, Anjana; Veitz-Keenan, Analia; Niederman, Richard
OBJECTIVES/OBJECTIVE:To investigate whether silver diamine fluoride (SDF) is effective in preventing new caries lesions in primary teeth when compared to placebo or active treatments. METHODS:Systematic review (CRD42016036963) of controlled clinical trials. Searches were performed in 9 electronic databases, 5 registers of ongoing trials, and reference lists of identified review articles. Two researchers carried out data extraction and quality appraisal independently. The primary outcome was the difference in caries increment (decayed, missing, and filled surfaces or teeth - dmfs or dmft) between SDF and control groups. These differences were pooled as weighted mean differences (WMD) and prevented fractions (PF). RESULTS:Searches yielded 2,366 unique records; 6 reports of 4 trials that randomized 1,118 and analyzed 915 participants were included. Two trials compared SDF to no treatment, 1 compared SDF to placebo and sodium fluoride varnish (FV), and 1 compared SDF to high-viscosity glass ionomer cement (GIC). All studies had at least 1 domain with unclear or high risk of bias. After 24 months of follow-up, in comparison to placebo, no treatment, and FV, SDF applications significantly reduced the development of new dentin caries lesions (placebo or no treatment: WMD = -1.15, PF = 77.5%; FV: WMD = -0.43, PF = 54.0%). GIC was more effective than SDF after 12 months of follow-up but the difference between them was not statistically significant (WMD, dmft: 0.34, PF: -6.09%). CONCLUSION/CONCLUSIONS:When applied to caries lesions in primary teeth, SDF compared to no treatment, placebo or FV appears to effectively prevent dental caries in the entire dentition. However, trials specifically designed to assess this outcome are needed.

Silver diamine fluoride versus therapeutic sealants for the arrest and prevention of dental caries in low-income minority children: study protocol for a cluster randomized controlled trial
Ruff, Ryan Richard; Niederman, Richard
BACKGROUND:Dental caries is the most prominent childhood disease in the world. In the United States, more than 50% of children have experienced caries. Untreated caries can have negative impacts on quality of life, academic performance, and school attendance. To reduce oral health disparities, multiple organizations recommend school-based caries prevention. METHODS/DESIGN/METHODS:A longitudinal, cluster randomized, non-inferiority trial will be conducted in low-income children from primarily Hispanic/Latino backgrounds currently enrolled in public elementary schools in New York City, New York, United States, from 2018 to 2023. The primary objective is to compare the non-inferiority of silver diamine fluoride and fluoride varnish versus glass ionomer therapeutic sealants and fluoride varnish in the arrest and prevention of dental caries. Secondary objectives are to evaluate differences in effectiveness when care is provided by nurses versus dental hygienists and assess the impact of prevention on oral health-related quality of life and educational outcomes. Caries arrest will be evaluated after 2 years, and caries prevention and secondary outcomes will be assessed at the completion of the study. Data analysis will follow intent-to-treat, and statistical analyses will be conducted using a two-sided significance level of 0.05. DISCUSSION/CONCLUSIONS:The comparative effectiveness of alternative caries prevention delivery models is considered to be one of the highest research priorities in the United States. Many treatments are currently available to prevent and arrest dental caries. The simplicity and affordability of silver diamine fluoride may be a viable alternative for the prevention of dental caries in high-risk children.
