Formaldehyde release from selected root canal sealers
Journal Title: Journal of Stomatology (Czasopismo Stomatologiczne) - Year 2009, Vol 62, Issue 12
Abstract
Introduction. Is formaldehyde still useful in modern dental practice? Some practitioners still routinely use devitalizing pastes containing paraformaldehyde. Also there are some root canal sealers on the market which release this compound.Aim of the study: To examine four root canal fillingmaterials for the amount of released formaldehyde.Materials and methods: The chosen materials included: AH Plus, Endomethasone N, EZ-Fill and N2 cement. Tests were performed with High Performance Liquid Chromatography method with 2,4-dinitrofenylohydrazin derivatization.Results: N2 cement released the highest amount of formaldehyde (2.91 mg; 2.91%). Significantly less formaldehyde was released from EZ-Fill (1864ppm; 0.186%). The amounts released from Endomethasone N and AH Plus were negligible (ca. 2ppm; 0.0002%).Conclusion: Endodontic materials releasing significant amounts of formaldehyde are still available on the market. However, according to this study, formaldehyde release cannot be the only criterion of the safety of endodontic materials.
