[Iatrogenic risks during the obturation of the root canal system].
A hermetic seal is the main goal of obturation of the root canal system. For that purpose guttapercha still remains the filling material of choice. Most filling techniques use plasticized guttapercha and a condensation technique to fulfil the requirements of hermetic seal. The heat to plasticize and the forces applied to condense that material may have an influence on the periodontal ligament and/or the remaining tooth structure. Furthermore can overfilling of guttapercha and more likely the sealer, affect the periodontal tissue. Although rare, mandibular nerve damage and adverse effects on the sinus maxillaris can be the result of inadequate treatment.
