This grant proposal aims to evaluate the efficacy of silver diamine fluoride (SDF) in arresting dental caries among nursing home residents. Despite advancements in dental care, caries remains a significant health issue for the elderly, particularly those in long-term care facilities. The proposed study will conduct a randomized controlled trial to assess the caries-arresting capabilities of SDF.

Silver diamine fluoride (SDF) offers several potential benefits in dental care, particularly in the management of dental caries. Its primary advantage lies in its ability to arrest caries effectively and efficiently, with studies showing it can stop around 40% of cavities in older adults. This is especially significant in populations like nursing home residents, who may face challenges in accessing traditional dental treatments. SDF's ease of application is another benefit; it can be applied quickly and without the need for drilling or anesthesia, making it a non-invasive option that is also painless. This aspect of SDF treatment is particularly advantageous for individuals with situational anxiety or special needs.

Moreover, SDF is cost-effective compared to other dental treatments, which can be a critical factor in public health settings and long-term care facilities where budgets may be limited. The fluoride in SDF helps to remineralize tooth enamel, strengthening teeth against future decay, while the silver component has antibacterial properties that kill the bacteria responsible for caries. 

Another significant benefit of SDF is its safety profile. Many studies and trials have indicated that there are no serious side effects associated with its use, aside from potential staining of the teeth, which is a cosmetic concern rather than a health issue. The application process is straightforward and it's simplicity contributes to the overall efficiency of the treatment.

The research will focus on the application of a 38% SDF solution in comparison to a fluoride varnish for caries arrest.

Apart from this trial, there will also be an in vitro evaluation of how SDF works in a simulated dry mouth.
