Best materials in the treatment of periodontitis
Recently scientists evaluated the healing outcomes of Intermediate Restorative Material (IRM) and mineral trioxide aggregate (MTA) materials as root-end seal of teeth with apical periodontitis. They found that both the methods are effective in the treatment of periodontitis. Teeth with previous conventional endodontic root-canal treatment may present persistent symptomatic or asymptomatic apical periodontitis. Such teeth could be a subject to periapical surgery using a modern technique with an expected good outcome. However, uninstrumented teeth with a need of conventional endodontic treatment can also benefit from such a surgical procedure. In a long-term perspective the orthograde retreatment of the root filling offers a more favorable outcome, 83% versus 72% for periapical surgeryafter 4-6 years. In contrast to that a meta-analysis from Kang et al. revealed a significantly higher success rate for periapical surgery in a short term perspective (less than 4 years) compared ...
