Formaldehyde release from ground root canal sealer in vitro
The formaldehyde release from three different ground root canal sealer materials was examined. Ten specimens each of AH26, Amubarut, and N2 were stored under dry conditions for 6 months. An amount of ∼100 to 200 mg ground material was obtained from each sample by using a round bur and stored for 10...

| Summary: | The formaldehyde release from three different ground root canal sealer materials was examined. Ten specimens each of AH26, Amubarut, and N2 were stored under dry conditions for 6 months. An amount of ∼100 to 200 mg ground material was obtained from each sample by using a round bur and stored for 10 min in distilled water. The formaldehyde concentration of the immersion water was determined by high-performance liquid chromatography. The mean formaldehyde release per mg material was 6.6 (±2.5) μg for AH26 and 8.3 (±1.0) μg for Amubarut. A lower formaldehyde release was detectable by our method from the N2 samples (0.3 ± 0.1 μg/g; p < 0.0001). In conclusion formaldehyde release from ground root canal material is low, although a risk of an allergic reaction in susceptible patients cannot be excluded. |
