INTRODUCTION: Although preventable, dental caries remains highly prevalent. Many children do not receive preventive dental services routinely in clinical settings. This review examined the effectiveness of school (preschool through high school) fluoride varnish delivery programs (SFVDP) in preventing caries. METHODS: Community Guide systematic review methods were followed. In 2024, databases were searched for studies published through December 2023 on SFVDP effectiveness in increasing fluoride varnish (FV) receipt and decreasing caries. Included studies had to be written in English, published in peer-reviewed journals, and conducted in upper-middle or high-income countries. Data synthesis conducted in 2024 used median RR and interquartile interval (IQI) to summarize findings across studies. RESULTS: Of 31 included studies with 60,780 students, 25 were randomized controlled trials-20 with good quality of execution. Most studies were conducted in low socioeconomic status (SES) areas among students at elevated caries risk. SFVDP reduced caries initiation by 32% (IQI: 21%, 37%) in permanent teeth (19 studies, 25,826 students) and by 25% (IQI: 4%, 37%) in primary teeth (12 studies, 4,304 students). Stratified assessments indicated findings were largely applicable to different settings, populations, and intervention characteristics. Two studies found SFVDP significantly increased the number of annual FV applications and two found that SFVDP effectiveness was inversely related to SES. DISCUSSION: About 30% of states report having no SFVDPs. Possible barriers to implementation include that Medicaid in some states only reimburses dental and medical professionals and does not reimburse non-dental providers for FV delivered to children older than 6 years.

INTRODUCTION: Employees are often placed within an organization based on their respective roles or duties, which can lead to vertical and horizontal organizational silos. Organizational silos may restrict information, resources, and stymie progress and innovation. This analysis presents a framework to mitigate silos and overcome communication barriers within an organization by increasing collaboration. METHODS: The project team examined results from the Centers for Disease Control and Prevention (CDC), the National Center for Chronic Disease Prevention and Health Promotion (NCCDPHP) 2020 Employee Viewpoint Survey Results and conducted 19 key informant discussions with NCCDPHP employees. Participants were asked to provide feedback on (1) understanding silos in the workplace and (2) best practices for reducing silos and fostering collaboration. A thematic analysis was conducted to understand organizational silos, the motivation to reduce silos, and identify best practices and strategies. RESULTS: Respondents felt that siloing exists at the division and branch levels; however, 95% of respondents were motivated to reduce silos. Fifty-eight percent of respondents identified that institutional factors such as the organizational structure (n = 8) and red tape/bureaucracy (n = 3) contribute to siloing. Additional behaviors and actions that perpetuate silos were identified, and efforts to reduce silos were categorized to propose a model: Framework to Foster Collaboration for improving organizational collaborative efforts. DISCUSSION AND CONCLUSION: Key themes included inclusion, shared goals and vision, bi-directional communication, and relationship building and developing trust as critical elements for improving collaboration and creating synergy across teams in efforts to reduce silos in the workplace.
