Solubility of Resin Based Root Canal Sealers

Objectives: In order to achieve a complete root canal treatment, the root canal must be biomechanically prepared and obturated three dimentionally with hermetic apical seal. Currently accepted obturation tecnique is obturating root canal space by gutta-percha with nonresorbable sealer. Ideal root canal properties was standardized by International Standards Organization. ISO 6876 (2001). In this study solubility properties of eight resin based sealers (Epiphany, GuttaFlow, Roekoseal, AH26, AHPlus, Diaket, FibreFill, EndoRez root canal sealers) was investigated and compared with Kerr Pulp Canal sealer.

Methods: Sealers were mixed according to the manufacturers instructions. Moulds (diameter:20 mm, height:1,5) filled with the mixed root canal sealers were placed in a petri dish in the cabinet at 37 °C and 95% relative humidity for 24 h (n:10). They were weighted nearest 0,001 g. After that they were immersed in 50 ml distilled water for 24 h. After placing the petri dish in a desiccator, the weight change of specimens were recorded.

Results: Kerr Pulp Canal sealer showed the significantly greatest weight loss of all sealers tested (p<0.05). AH26 was the least soluble root canal sealer (p<0.05). The solubility of all sealers were in accordance with ISO (6876/2001) requirements.

Conclusion: Resin based sealers showed less solubility than ZOE based Kerr Pulp sealer.
