Assessing preferences from the perspective of different social actors in decision-making related to minimal intervention strategies - a protocol guiding discrete choice and willingness-to-pay experiments to link clinical evidence to implementation
This protocol outlines a multicenter study in Brazil that employs discrete choice experiments and willingness-to-pay assessments to evaluate the preferences of children, caregivers, and society regarding minimal intervention dentistry strategies, aiming to bridge the gap between clinical evidence and practical implementation in pediatric dental care.

For decades, the scientific community has known that the best way to treat tooth decay in children is often to do as little as possible. This approach, known as minimal intervention, focuses on stopping the spread of disease with gentle methods rather than aggressive drilling. Yet, a stubborn gap remains between what science says should happen and what actually occurs in dental clinics and public health policies. The missing link is often human preference. Just because a treatment is scientifically sound does not mean patients, their families, or the taxpayers who fund public health systems will accept it. To bridge this divide, researchers must understand what different people value when they face a choice about a child's dental care. Is it the cost? The number of visits? The fear of pain? Or the speed of recovery?
This question is particularly complex when children are involved. While parents usually make medical decisions for their young ones, the child is the one who experiences the treatment. Furthermore, in a public health system, the entire society acts as a stakeholder, funding these services through taxes. A new study protocol from a large team of researchers across Brazil aims to map these preferences with unprecedented detail. By listening to children, their caregivers, and the general public, the team hopes to create a roadmap for implementing evidence-based dental care that respects the values of everyone involved.
The researchers are launching a massive, multi-center effort across all five geographical regions of Brazil to gather these insights. They are not simply asking people what they prefer; they are using a method called a discrete choice experiment. In this setup, participants are presented with a series of hypothetical scenarios. Imagine a parent being asked to choose between two different ways to treat a cavity. One option might be a quick, painless procedure that costs more, while the other might be a slower process that requires multiple visits but is free. By forcing people to make trade-offs between different features like time, cost, and discomfort, the researchers can uncover what truly drives their decisions, rather than relying on what people say they would do in a perfect world.
To ensure these findings reflect the true diversity of the population, the study employs a strategy known as citizen science. Instead of relying solely on university students or clinic patients, the team is training ordinary citizens to recruit and interview their own peers. This approach reaches people in remote areas and from varied socioeconomic backgrounds, ensuring that the data captures a wide range of experiences. The study targets three distinct groups: children aged six to ten, their parents or caregivers, and adults without children who represent the broader society. This inclusion of children as direct participants is a significant departure from standard practice, where adults often speak on behalf of the young. The researchers recognize that a child's view of a dental visit is fundamentally different from their parent's, and both perspectives are necessary for a complete picture.
The project is carefully structured to handle the unique challenges of asking young children about complex medical choices. The team is developing special tools that use pictures and simple language to help children understand the scenarios. They are testing these instruments with small groups first to ensure the questions make sense and do not cause confusion or distress. Once the tools are refined, the main data collection will take place in a virtual environment, allowing participants to complete the surveys from their homes. Alongside the choice experiments, the researchers will also ask participants how much they would be willing to contribute financially to make these preferred treatments available to everyone. This "willingness to pay" assessment helps translate abstract preferences into concrete economic values, which is crucial for policymakers deciding how to allocate limited public funds.
The ultimate goal of this work is to generate evidence that can guide health officials and dental professionals. By understanding exactly what different groups value, the team hopes to design treatment plans and public health policies that people are more likely to accept and follow. If a new, gentle treatment is scientifically superior but fails because it requires too many visits, the data from this study could reveal that specific barrier. Conversely, if the public is willing to pay more for a faster solution, that insight could justify changes in funding. The researchers are not claiming to have solved the problem of dental care implementation yet; rather, they are building the essential foundation of knowledge required to do so. By aligning scientific evidence with the actual values and preferences of the people it is meant to serve, this study aims to make the transition from the laboratory to the clinic smoother, more equitable, and more effective for children across Brazil and potentially beyond.
