Abstract
Objective To compare the capacity of silver diamine fluoride (30%) and the bioactive giomer light-curing varnish for arresting ICDAS score 5 non-retentive caries lesions. Material and Methods An in vitro analytical study was conducted using 36 healthy primary teeth, in which a cavity was created, divided into 3 groups: control (distilled and deionized water), giomer-based light-curing varnish – Barrier Coat, and Silver Diamine Fluoride 30% – Cariestop (SDF). The samples were analyzed for mineral loss as measured by surface microhardness (SMH).The Knoop microhardness test was performed using the HVS-1000 microhardness tester. The data were compared by two-way analysis of variance – treatment and time (before and after treatment) followed by Tukey’s post-test. The significance level adopted in all analyzes was 5%. Results The specimens treated with giomer showed higher SMH compared to the untreated group but were similar to those of the SDF group. The SDF group, on the other hand, showed no statistically significant difference from the control group (p=0.010). Conclusion The giomer varnish had a remineralizing effect on artificial dentinal caries.
Highlights
Dental caries remains a global health problem and is considered one of the most common chronic diseases in the world [1,2]
The 30% Silver Diamine Fluoride (SDF) is a medication used for caries arrest, whose mechanism of action is based on its ability to increase enamel surface microhardness (SMH) and reduce mineral loss [1]
The SDF group showed no significant difference from the control group
Summary
Dental caries remains a global health problem and is considered one of the most common chronic diseases in the world [1,2]. The most affected population is young children, and their cooperation during restorative procedures is not always satisfactory. Alternative, easy-to-perform, and cost-effective treatments are indicated to treat dental caries in children [3,4]. There has been a greater interest in non-invasive treatments, and studies show their comparable efficacy with conventional restorative methods [5,6]. More than 20 clinical studies conducted worldwide have demonstrated the effectiveness of SDF in arresting caries [3]. In a recent systematic review, 38% SDF was shown to be effective in arresting lesions in primary teeth, with an overall success rate of 81%, suggesting that this may be a promising strategy for treating caries in young children or in patients with special needs [2]. A disadvantage is that the arrested caries is discolored brown-black
