Weight loss of endodontic sealers, cements and pastes in water

Abstract – A solubility test based on weight loss in water, as proposed for standard testing programs (ADA & ISO), was adapted for assessing the solubility of 10 root canal sealers, cements and pastes. The weight loss of the set materials during 24 hr in distilled water at 37°C ranged from –0.84 (AH26) to 22.71 (Kloroperka N-Ö) weight percent. The results were reproducible, and the test was considered suitable for routine testing of weight loss in water of endodontic materials. However, the test may not provide information which is directly related to the clinical behavior of the materials.
