Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Objectives: This pilot study aims to evaluate the impact of SDF on the oral health of the elderly living in long-term care facilities.
Principal objective: evaluate effectiveness of SDF on arrestation of active caries when applied for the elderly with loss of autonomy in long-term care facilities.
Secondary objectives:
1. evaluate the relationship between SDF application and caries activity
2. Analysis of salivary biomarkers involved in the associated inflammatory processes.
Methodology: A randomized controlled feasibility and effectiveness study design will be employed. This study will span over 12 months and will include 3 data collection phases.
At T0 (baseline): SDF group participants will receive an SDF application on their active caries. Control group participants will receive a 0.9% saline solution (placebo) application.
AT T1, 6 months after T0: First phase of data collection, the two groups will receive SDF application.
At T2, 12 months after T0: second phase of data collection, and for ethical reasons, the control group, who received placebo at T0, will receive an SDF application.
At the end of the project, a fluoride varnish application will be carried out on both groups to prolong preventive effects of treatment. A short questionnaire will also be shared with participants to evaluate their satisfaction and identify unintended adverse effects.
Anticipated results:
Demonstrate the efficiency of SDF in controlling active caries in the elderly with autonomy loss.
Elaborate a clinical protocol for SDF application in long-term care facilities Establish the required sample size for a future bigger study.
