The goal of this observational study is to learn how well and how safely silver diamine fluoride (SDF) stops tooth decay (caries) in baby teeth when it is used in routine dental care. It will include children aged 14 years or younger with caries in their primary (baby) teeth who are treated with SDF at a public primary care dental clinic. The main questions it aims to answer are:
Dental caries is one of the most common chronic diseases in childhood and remains a public health problem, especially in primary teeth and in children from lower socioeconomic backgrounds attended in the public health system. Topical 38% silver diamine fluoride (SDF) is a minimally invasive treatment that arrests caries progression, with arrest rates above 70% in controlled trials. However, there is little evidence on its effectiveness and safety in routine clinical practice, particularly with current formulations that use water instead of ammonia as the vehicle and include potassium iodide to reduce staining.
This is a single-cohort prospective study conducted at the Dentistry Service of the Baix a Mar Integrated Primary Care Center (Consorci Sanitari de l'Alt Penedès i Garraf). Children with caries in primary teeth who have an indication for SDF according to the Catalan Health Department guideline "Implementation of silver diamine fluoride treatment in primary and community care dental clinics: rationale and protocol for use" will be invited to participate. SDF 38% (Riva Star) will be applied according to that guideline. Participants will be assessed at baseline and at 1, 6, and 12 months. At each follow-up, the investigator will rate caries progression (yes/no) based on visual appearance (dark, shiny, smooth surface), tactile assessment with a dental probe (hard, smooth, not sticky), absence of symptoms, stability over time, and radiographs if needed.
The primary analysis will estimate the proportion of treated lesions without progression at 12 months with its 95% confidence interval. Logistic regression will be used to explore factors associated with progression, and subgroup analyses by sex and age are planned. A sample of 101 participants allows the proportion of arrested lesions (expected around 70%) to be estimated with a precision of ±10 percentage points and 95% confidence, assuming a 20% loss to follow-up.
1,171 studies on the registry are indexed under Dental Caries; 209 are open to participants now.
This study's planned enrollment of 101 is below the median of 174 across 187 observational studies indexed under Dental Caries.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Children aged 14 years or younger with caries in primary teeth and an indication for SDF according to the Catalan Health Department guideline
Drug: Silver diamine fluoride 38%
Topical application of 38% silver diamine fluoride to caries lesions in primary teeth, following section 4.3 ("Guidelines for the use of SDF in primary and community care") of the Catalan Health Department guideline, as part of routine clinical practice.
Proportion of treated caries lesions without progression
Number of caries lesions without progression divided by the total number of caries lesions treated with SDF. Progression (yes/no) is rated by the investigator based on visual appearance, tactile assessment with a dental probe, absence of symptoms, stability over time, and radiographs if needed.
Time frame: 12 months after SDF application
Plan to share: Yes — IPD (without personal identification data) could be shared by requirement from other researchers after the end of the study, and only for research purposes and previous approval of promotor center of the study (CSAPG). Anyway, Spanish and European Union legal policy about data protection will strictly be followed (IPD will not be transferred outside European Union).
Supporting information: Study protocol
Time frame: After publication of main results of the study.
Access criteria: IPD will be shared only for scientific research purposes and following the Spanish and European Union normative law about data protection. The requirements will be directed to the IP of the study. The IP will evaluate the request to verify and evaluate the data that is requested and the purposes for which it is requested. Next, the IP will transfer the request to the promotor center the study for the final decision.

Started Sep 2026 (actual). Primary completion is estimated for Dec 2028, 27 months after the start.
Of 46 non-industry observational studies under Dental Caries, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 32. This study's planned 27 months is above that.
Counting every sponsor, half of 47 studies reached it within 12 months; a quarter within 7 and three quarters within 32.
