Abstract

Abstract
Purpose: This study aimed to determine whether pretreating primary molars with silver diamine fluoride and potassium iodide (SDF + KI) under resin modified glass ionomer restoration (RMGI) affect the fluoride uptake into dentine or not. Methods: Twenty carious extracted primary molars were sectioned mesio-distally forming two similar halves into forty sections. Each tooth was placed in a separate container with its 2 halves. Teeth were then randomly allocated either to the control or intervention group. In each tooth, the caries was excavated in each half. The control group received resin modified glass ionomer. The intervention group received silver diamine fluoride and potassium iodide followed by resin modified glass ionomer. After 2 weeks, fluoride percentage by weight in dentine was measured in both groups using energy dispersive x-ray analysis (EDX). Results: In the RMGI control group, there was a significant increase in the amount of fluoride weight percentage from (0.81±0.47) to (3.49±1.88) after restoration placement (p < 0.001). In the SDF + KI intervention group, there was a significant increase in the amount of fluoride weight percentage from (0.47±0.44) to (4.14±1.45) after restoration placement (p < 0.001). There was no significant difference between the mean amount of fluoride weight percentage measured in the control group (3.49±1.88) and the intervention group (4.14±1.45) with (p=0.398). Conclusion: The application of silver diamine fluoride and potassium iodide under resin modified glass ionomer restoration does not interfere with the fluoride uptake from glass ionomer into dentine.
