Abstract
Aim: One of the preventive interventions for early childhood caries is the use of silver diamine fluoride (SDF), which works uniquely in the prevention of caries. The suggested method to minimize the discoloration of SDF is the use of potassium iodide (KI). However, there are concerns about the bonding properties of dentin after the application of SDF-KI. Therefore, this study aimed to investigate how SDF-KI affects composite resin microleakage in primary teeth.
Materials and methods: In this in vitro study, class V cavities were created on the buccal surfaces of 60 extracted primary canines. The samples were divided into three groups: Group I: 38% SDF solution was applied to the cavity; Group II: SDF-KI solution was applied to the cavity; and group III: the cavities were irrigated with distilled water. All cavities were filled with composite resin and subjected to a thermocycling regime (500 cycles). The dye penetration of samples was evaluated following a 24-h immersion in 1% methylene blue. Microleakage at the occlusal and gingival margins was evaluated using a stereomicroscope at 40× magnification. Data were analyzed using the Chi-squared test (p < 0.05).
Results: There was no statistically significant difference between microleakage scores at the occlusal margin (p = 0.128). At the cervical margin, the SDF-KI group had significantly more microleakage than the SDF and control groups (p = 0.001).
Conclusion: Applying the SDF-KI significantly increased microleakage in the cervical margin but had no significant effect on the occlusal margin.
Clinical significance: Regarding the beneficial effects of SDF in preventing and arresting dental caries, application of it before composite resin is suggested in controlling caries without the negative effects on microleakage.

期刊介绍：
The Journal of Contemporary Dental Practice (JCDP), is a peer-reviewed, open access MEDLINE indexed journal. The journal’s full text is available online at http://www.thejcdp.com. The journal allows free access (open access) to its contents. Articles with clinical relevance will be given preference for publication. The Journal publishes original research papers, review articles, rare and novel case reports, and clinical techniques. Manuscripts are invited from all specialties of dentistry i.e., conservative dentistry and endodontics, dentofacial orthopedics and orthodontics, oral medicine and radiology, oral pathology, oral surgery, orodental diseases, pediatric dentistry, implantology, periodontics, clinical aspects of public health dentistry, and prosthodontics.
