Avaliação dos efeitos do diamino fluoreto de prata associado ao iodeto de potássio sobre a cárie dentária

Abstract

Introduction: Dental caries persist as a highly prevalent global disease. As an alternative solution, silver diamine fluoride (SDF) has been used, which acts in remineralization and as a cariostatic agent. However, it causes discoloration of the treated surface. To reduce this staining, potassium iodide (KI) as been applied after its use. Objective: To evaluate the current scientific literature on the effects of the SDF+KI combination on dental caries. Methodology: An analysis of articles from the PubMed, Lilacs, and Scielo databases was conducted in English and Portuguese, using the keywords: silver diamine fluoride; potassium iodide; dental caries, and their Portuguese equivalents, along with the boolean operator AND. Results: Twelve articles were identified, revealing that the combination of SDF+KI is beneficial for caries as it inhibits bacterial growth, though it removes important silver compounds necessary for treatment. While KI initially reduces discoloration, it is photosensitive and dissociates when exposed to light, resulting in darkening. Conclusion: Although the combination of SDF+KI is advantageous, SDF alone demonstrates greater efficacy. KI initially decreases discoloration, but the surface tends to darken over time.
