Analysis of trace elements released from glass ionomer restorative materials by inductively coupled plasma-mass spectrometry
The aim of this study was to determine the amount of trace elements released from a traditional glass ionomer, a bulk-fill glass ionomer, a resin-modified glass ionomer, a glass carbomer fill and a compomer material stored in ultra-distilled water.
Ten cylindrical (10×2mm) specimens were prepared from each material. Each sample was stored in 50mL ultra-distilled water at 37°C for fourteen days, and rinsed twice daily. The amount of elements in the solutions was determined using inductively coupled plasma-mass spectrometry.
Aluminum, boron, nickel, copper, zinc, barium and lead were detected in all solutions. The traditional glass ionomer and resin-modified glass ionomer released arsenic, the bulk-fill glass ionomer and compomer released selenium, and the resin-modified glass ionomer and compomer released antimony. Only the resin-modified glass ionomer released iron.
All materials tested released some trace elements, but the rates were quite low. Therefore, these glass ionomer materials can be used safely in dentistry.
