SDF With or Without Fluoride Varnish for Caries Arrest in Primary Teeth of Young Children

Tooth decay (dental caries) occurs when acids dissolve tooth structure. If not treated, cavities in primary teeth can progress quickly, leading to caries, infection and early tooth loss. These problems may affect chewing, speech, nutrition, and overall health. In Albania and many other countries, cavities in young children are very common. Standard dental treatments are often difficult in very young or uncooperative children and may require sedation or general anesthesia. Silver diamine fluoride (SDF) is a liquid medication that can be painted directly onto cavities. SDF stops cavities from worsening by killing bacteria and hardening softened tooth surfaces. The main side effect is dark staining of the treated area. Despite this, SDF is considered safe and effective, especially for children who cannot tolerate conventional treatment. Fluoride varnish (FV) is another preventive treatment applied to all tooth surfaces to strengthen enamel and help prevent new cavities. The purpose of this study is to compare two approaches for managing tooth decay in young children who have difficulty cooperating for dental care: * SDF applied to cavities every six months. * SDF applied every six months, with FV applied to all teeth every three months. A total of 104 children between the ages of 1.5 and 8 years with active cavities in their primary (baby) teeth were enrolled. Children were randomly assigned to one of the two treatment groups. The children were followed for 24 months. The main outcome measured is whether cavities became arrested, meaning the surface became hard and inactive with no further breakdown. Additional outcomes include whether combining SDF with FV provides added benefit and whether baseline factors such as oral hygiene and diet influence treatment success. The information from this study may help dentists and parents understand how SDF, with or without FV, can be used as a safe, effective, and child-friendly option to manage cavities in young children.
