S. Huumonen, M. Lenander-Lumikari, A. Sigurdsson & D. Orstavik NIOM, Scandinavian Institute of Dental Materials, Haslum, Norway. University of Turku, Finland. University of North Carolina at Chapel Hill, USA. Aim. To assess the treatment results up to 1 year after endodontic treatment of apical periodontitis using a silicone-based sealer in comparison with Grossman’s sealer, and to compare the results at 3 months after treatment with the 12-month follow-up to assess the prognostic value of a 3-month control. Results and conclusions. Average PAI scores decreased from 3.43 at start to 2.21 at 12 months for Grossman’s sealer and from 3.40 to 2.26 for the silicon based material. No significant difference between the groups at start or any of the follow ups was seen. The 3-monthcontrolwas adequate in establishing significant healing in both groups. The improvement of the periapical condition continued at the12-monthexamination. Journal of Endodontics Research
